Morocco Aims To Double Electric Vehicle Production In Two Years

Morocco aims to double its electric car production by 2024, Morocco World News reports. According to Ryad Mezzour, the Moroccan minister for trade and industry, the country is on track to start manufacturing as many as 100,000 electric cars per year within the next two to three years. Fortunately, Morocco’s existing industrial facilities alone are capable of reaching this lofty goal, although helpful international investment may also be on the table in coming years.

Electric Vehicle Production in Morocco

The need for electric vehicle production

Ramping up electric car production is becoming increasingly essential to maintain a competitive edge in a global market. Net zero carbon emission commitments, a sustainable goal pledged by countries around the world, now mean combustion engine vehicles no longer have a bright future in terms of market outlook.

The European Union, for example, Morocco’s largest trade partner, has voted to ban imports of fossil-fuel cars from 2035. Although Morocco is already the biggest carmaking hub in Africa, the country needs to prioritize the shift to electric vehicles in order to stay ahead. As such, Morocco’s now aiming for an electric vehicle production target of one million units per year, as well as to increase national auto part manufacturing in order to reduce dependence on imports.

Saving money while helping the environment

Better for the environment and offering lower servicing and maintenance costs, electric cars are becoming an increasingly popular choice across the world. Although Moroccan authorities have yet to roll-out financial incentives to further increase electric vehicle adoption, other countries do offer these as a way of boosting clean energy use.

The United States, for example, offers a $7,500 federal income tax credit for all new electric cars purchased in or after 2010. A number of states and utility companies also offer hundred-dollar rebates for at-home electric vehicle charger installation. Although a home charger is an ample investment (around $1,300 in total), it can help people save time and money by being able to charge their electric vehicles without leaving home. For standard 240-volt home outlets, plug-in chargers are ideal. Fortunately, plug-in charging systems can be easily upgraded without the need for an electrician.

Environmental Impact of Electric Vehicles

Morocco’s cobalt reserves attractive to electric car manufacturers

International car manufacturers are already favoring Morocco for the country’s ample cobalt reserves, a crucial material used to produce electric vehicle batteries. In fact, Morocco is home to the 11th largest cobalt reserves in the world. In particular, last year, Groupe Renault, the French multinational car manufacturer, partnered with Managem Group, a mining company, to secure a cobalt supply from Morocco. The agreement states Managem Group will provide Renault with 5000 tonnes of cobalt sulfate for seven years. The first shipment will be provided in 2025.

Car exports also play a key role in Morocco’s status as Africa’s auto manufacturing leader — cars are the country’s second biggest exporting sector with exports expected to reach $5.6 billion by the end of 2022. And, with the boost to electric vehicle production, Morocco’s transition  to green, zero-emission vehicles is set to be a success.

Energy from Wastes via Thermal Route

Thermal (or thermochemical) conversion systems consist of primary conversion technologies which convert the waste into heat or gaseous and liquid products, together with secondary conversion technologies which convert these products into the more useful forms of energy being heat and electricity.

A wide range of technologies exists to convert the energy stored in wastes to more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which oxygen is admitted to the conversion process (usually as air).

The three principal methods of thermall conversion corresponding to each of these energy carriers are combustion in excess air, gasification in reduced air, and pyrolysis in the absence of air.

Combustion

Conventional combustion technologies raise steam through the combustion of wastes. This steam may then be expanded through a conventional turbo-alternator to produce electricity. Fluidized bed combustors (FBC), which use a bed of hot inert material such as sand, are a more recent development. Bubbling FBCs are generally used at 10-30 MWth capacity, while Circulating FBCs are more applicable at larger scales.

Gasification

Gasification of wastes takes place in a restricted supply of oxygen and occurs through initial devolatilization of the biomass, combustion of the volatile material and char, and further reduction to produce a fuel gas rich in carbon monoxide and hydrogen. This combustible gas has a lower calorific value than natural gas but can still be used as fuel for boilers, for engines, and potentially for combustion turbines after cleaning the gas stream of tars and particulates. 

Pyrolysis

Pyrolysis is the term given to the thermal degradation of wood in the absence of oxygen. It enables wastes to be converted to a combination of solid char, gas and a liquid bio-oil. Pyrolysis technologies are generally categorized as “fast” or “slow” according to the time taken for processing the feed into pyrolysis products. Using fast pyrolysis, bio-oil yield can be as high as 80 percent of the product on a dry fuel basis. Bio-oil can act as a liquid fuel or as a feedstock for chemical production. 

Green Building Sector in the Middle East: Sustainability Perspectives

Green buildings are no longer a marginal concept but are becoming the standard for sustainable building construction and modernization in the Middle East. Forward thinking organizations can realize the benefits of being environmentally aware of the impact of each and every action undertaken in the present world of development. It is no longer about the financial bottom line and whether we are eco-friendly, it is a fundamental component of sustainability. Institutes and organizations in the Middle East can embrace green building initiatives as a mandate, while educational institutes can embrace it as a good citizen initiative developing the minds of young people into being caring and concerned citizens of the planet.

Certification of Green Buildings

The Leadership in Energy and Environmental Design (LEED), developed in the USA,  offer directives for both new construction and renovation of already existing buildings. In the USA, LEED certification is required for buildings over a specified floor area, namely 5,000 square feet. There are other green building initiatives originating in the UK and Europe, and in the GCC region as well. The basic premises are similar regardless which system one chooses for building certification.

This is not a single sustainable system but are a range of standards that can be incorporated into new construction or existing buildings. The basic premise is to provide standards for the building owner and the building operators to reference and adhere to in order to operate and manage a sustainable building environment.

With the LEED rating system, there are four levels of certification starting at Certified and progressing to Silver, Gold and Platinum ranking. The ranking is awarded based on number of credits achieved when the overall building performance is benchmarked against the standards. The main areas where the building is benchmarked is in terms of energy efficiency, water conservation and indoor air quality.

The challenge is in utilizing the system with existing buildings as the greater majority of buildings already exist compared with the number of proposed new construction sites. Energy consumption is the greatest sector that can be addressed in terms of efficiency. This is critical, especially with the urgency to mitigate climate change and lower greenhouse gas emissions (GHG), conserve water and manage waste product better.

Identifying the Best Sustainability Strategy

The first step is to identify the best sustainability strategy for an organization based on the present level of sustainability, possible options for achieving greater sustainability, as well as the estimated costs and likely benefits. The main areas of sustainability concerns include energy efficiency, water conservation, indoor air quality, environmental quality, construction materials and site sustainability. To undertake sustainable measures for all areas at once is not a good practice because of the cost involved.

net-zero-energy-building

Net Zero Energy Buildings rely on exceptional energy conservation and on-site renewable generation to meet energy requirements..

Therefore, the preferred area for implementing sustainable best practice measures often first address the energy efficiency areas as these measures can have significant cost savings. The evaluation focuses on electrical and mechanical systems, as well as the potential for renewable energy usage. The identification of possible changes to improve the energy efficiency should reduce energy consumption rates by modifying operational procedures. This may be achieved by installing energy efficient light sources, light sensors, and even retro-commissioning air conditioners and/or heat systems.

Water

Water consumption is of growing concern. Therefore, water usage and water recovery and reuse after treatment are all viable considerations. The best practices include managing the water flow at the faucet and the flush system in toilets. These are the two main consumer areas. Other measures depending on location could include harvesting of rainwater and method of irrigation.

Indoor Air Quality

Indoor quality covers several areas such as air quality, thermal comfort and lighting quality. Lighting quality can be improved significantly by using natural light source as mush as possible. Adequate clean, fresh air is critical for the overall well being of the building occupants. This may require the replacement of materials in the building that give of toxic fumes. It could also require changing processes conducted indoors.

Another critical area is to eliminate emission of ozone depleting gases from HVAC systems, fire suppressant materials and refrigerant gases. Many of the latter are already well addressed in developed regions of the globe.  But this is not the case in the less developed regions of the globe.

Waste Minimization

Waste reduction in materials and construction is achieved through waste management processes. This is best achieved through waste management and recycling initiatives. Analysis of cleaning products is another means of improving the overall air quality within buildings. Also, the use of natural building materials is preferable to man-made products.

Sustainable Indoors and Outdoors

The final area to consider is making the overall area – both indoors and outdoors –  more sustainable. This can be reflected in exterior lighting system, landscape of the grounds.  e.g. using xeriscape techniques in desert regions, selecting native plant species better suited to the outdoor conditions, and so on. Transportation options that are more favourable for “green” focus and sustainability are the ideal where employees are encouraged to carpool, as just one example. One measure that has become very popular in Bahrain is capturing solar energy from car parking shade roofing.

The Way Forward

By conducting energy, water and air quality audits, proposed sustainable measures can then be incorporated into large scale organizational planning strategies that make the organization operational procedures “green” and sustainable. These “green” initiatives can be implemented in operational procedures, maintenance and upgrade, as well as in new construction.

Initial implementation typically focuses on low-cost initiatives that have a short-term payback by reducing energy and other resource consumption rates. Over time, sustainable initiatives will highlight the short-term and long-term benefits in terms of environmental, economic and social factors. Ultimately buildings can ensure maximum operational efficiency while achieving a sustainable built environment.

مقدمة عن زراعه الاسطح الخضراء

green-roof-arabicتعتبر زراعه الاسطح من التكنولوجيا التي توفر مجموعة كبيرة من الفوائد الملموسه وغير الملموسه للمجتمعات المهتمة بتحسين وتعزيز بيئة جيدة.للأسقف الخضراء فوائد عديدة فهي تعمل على تنظيم حرارة المبنى ,فتقوم بتدفئته خلال الشتاء و تبريده خلال الصيف كما تساهم فى تقليل مياه الامطار المتسربة من الاسطح، ذلك لأنها تعمل كإسفنجة ماصة للمياه و في الوقت نفسه تستفيد النباتات من هذه المياه.

 كما تقوم الأسقف الخضراء على تقليل التلوث حيث تعمل كفلتر لتنقية الهواء. ومن فوائد الأسقف الخضراء قيامها  بدور هام فى تقليل الضوضاء و التى تعتبر من مشاكل العصر الحديث خاصة فى المدن. كما يجب ان لا  ننسى أن للأسقف الخضراء فوائد اقتصادية عديدة فهى تزيد من عمر المباني حيث تعمل كعازل حراري بحجبها أشعة الشمس عن أسطح المبانى كما تقلل من تكاليف تكييف الهواء خلال الصيف و التدفئة خلال الشتاء.

ما هي الاسطح الخضراء

النظم المستخدمة لزراعة أسطح المباني يجب ان تكون نظاماً خفيف الوزن لا يسبب حمولة زائدة علي المبني، كذلك يجب ان لا يحدث تسريب للمياه من النظام لسطح المبنى حتى يتم الحفاظ على المبنى بصورة جيدة ولفترة طويلة. و قد وجد أن الزراعة بدون تربة بأنظمتها المختلفة وأشكالها المتنوعة هي الاسلوب الامثل لزراعة السطح.

الاسطح الخضراء ممكن ان تتكون من اشجار, نباتات او شجيرات. وعمق وكثافه الطبقة المنبته للزراعه تنقسم الي نوعين مختلفين.

فالاسطح الخضراء ممكن ان تكون مكثفة او قليله الكثافة علي نطاق واسع. فالاسقف المكثفة تكون اكثر سمكا (اكثر من 15 سم عمق), وهي سماكة تسمح لنمو مجموعه متنوعه من النباتات والاشجار والشجيرات. ولكنها ثقيله علي السطح ومكلفه اكثر, وتتطلب المزيد من الصيانة والري.

والنوع الاخر يغطي طبقة خفيفة من الغطاء النباتي وذات سماكة اقل من 15 سم. وهي مخصصه للشجيرات والاعشاب التي لا تتطلب عمق كبير داخل التربة للنمو.

يستخدم نظام ترابيزات المراقد لانتاج المحاصيل التي لا تحتاج إلى حيز كبير لنمو جذور النباتات  مثل  المحاصيل  الورقية  كالجرجير،  الفجل،  البقدونس،  الكسبرة  والشبت.  كذلك يمكن باستخدام هذا النظام زراعة العديد من النباتات الطبية والعطرية والتي تستخدم في البيوت بكثرة كالنعناع، الزعتر، الريحان, وغيرهم.

والاسطح الخضراء علي مساحات واسعه وكثافه بسيطة يتم صيانتها مرتين سنويا عندما تحتاج التربه للترطيب والتسميد, فلها ميزة ان استدامتها ذاتية .

بيئة الزراعة المستخدمة

يجب ان تتوافر في بيئة الزراعة المستخدمة فوق الاسطح عدة مواصفات يمكن ان تلخص بما يلي :

1.      ان توفر البيئة الرطوبة اللازمة لنمو الجذور.

2.      ان توفر البيئة التهوية اللازمة لنمو الجذور.

3.      ان لا  تحتوي البيئة علي مواد ضارة او سامة.

4.      ان تكون البيئة خالية من المسببات المرضية.

5.      ان تكون البيئة خالية من الاملاح .

6.      ان تكون البيئة خالية من بذور الحشائش.

7.      أن تكون البيئة خفيفة الوزن.

8.      أن تتميز البيئة بسهوله تنظيفها و تعقيمها.

9.      سهوله توفر البيئة, مع سهوله عمليات النقل.

10.  ان تكون تكلفه البيئة معتدلة.

ويوجد العديد من المواد التي يمكن استخدامها كبيئة للزراعه فوق الاسطح. وتنقسم الي قسمين رئيسين هما: بيئات عضوية مثل بيئة سرس الارز. او البيئات غير العضوية مثل بيئة البرليت. ويمكن ان تسنخدم البيئات السابقة بصورة منفردة او تخلط معا للوصول الي افضل توليفه تلائم النباتات المزروعه.

اما بالنسبة للاشكال المختلفة لنظم مزارع البيئات فوق الاسطح, فهناك نظام الترابيزات المراقد وتستخدم للنباتات التي لا تحتاج الي حيز كبير لنمو الجذور. نظام ترابيزات الاصص وتسنخدم للنباتات التي تحتاج الي  حيز كبير نسبيا حتي تنمو الجذور مثل الطماطم. وهناك نظام لانتاج بعض اشجار الفاكهة فوق الاسطح مثل البراميل سعه 60 لتر لانتاج بعض الاشجار مثل الليمون.

بسبب الحمل المنشأ من استخدام الاسطح الخضراء الكثيفه فانها تستخدم بشكل اكبر في المباني التجاريه. حيث ان المباني التجارية اكثر تحمل لكونها اقوي من الناحية الخرسانيه, فانها تستطيع تحميل الاوزان الزائدة عنها في المباني السكنية.

بمجرد تجهيز التربة ووضع النباتات المطلوبة وترطيب تربتها, فان السطح المزروع ممكن ان يزن 150 بوند/القدم المربع. ويراعي لخلق جو اخضر وطبيعي للزائريين. ان ييكون هناك اماكن جلوس, مناضد, كراسي وممرات. الامر الذي يخلق بيئة من الطبيعه والهدوء.

والاسطح الكثيفة ذات الاشجار الاكبر حجما تساعد اكثر من النباتات علي الهدوء والاستراخاء, وخلق بيئة قريبة من المتنزهات والحدائق.

وعلي جانب اخر فان الاسطح الاكثر انتشارا والاقل كثافة تكون افضل للمباني السكنية و المدارس. فهي سهله التركيب والصيانة وممكن ان تضاف الي المبني بعد بدء الاسكان بدون تخوف من الاحمال الزائدة. ايا كان نوع النباتات او الشجيرات المستخدمة فانه يمكن اضافة وزن 10-35 بوند/القدم المربع, لاجمالي أحمال السطح. الحشائش والنباتات غير المستهلكة لكثير من الماء من الانواع التي تجد استحسان للزراعة فوق السطح وذلك نظرا لاستخدامها القليل للماء وجذورها القصيرة.

 ومن أهم فوائد الاسطح الخضراء انها صالحة للمباني القديمة والحديثة.

 والانظمة المستخدمة للزراعه يمكن ان تكون وحدات بطبقة صرف وطبقة فلترة من القماش وطبقة انبات بنوع معين, وشبكة ري وصرف متشابكة. والنباتات المستخدمة والتي تكون مسبقة التجهيز خارجيا, البوتقات المستخدمة التي تكون منفصله عن النظام او مركبة جزء منه. وهذا النظام يسمح بتكوين النظام بشكل منفصل.

green-roofs-middle-east

تختلق التقارير  التي توضح تكلفة النظام المتسع والاقل كثافه للتربه المستخدمة ليكن في المتوسط لزراعه النظام المتسع ما بين 8-20 دولار/ للقدم المربع. وبالنسبة للنظام الكثيف مابين 15-50 دولار/القدم المربع. وبالمقارنة للاسطح التقليدية المزروعه والتي تكون في المتوسط 16 دولار/القدم المربع وقد يعلو عن ذلك في التكلفة. ولكن بالرغم من ذلك فان ما توفره الاسطح الخضراء من فوائد بيئية وجمالية وصحية هي اكثر بكثير من التكلفه المتوقعه للتنفيذ.

فوائد الاسقف الخضراء

الاسطح الخضراء لديها القدرة علي خفض متطلبات الطاقة بطريقيتين:

امتصاص الحرارة واعتبارها عازل حراري للمبني. فاضافه طبقه من التربة والنباتات الي السطح يزيد طبقة العزل الحراري علي السطح. فالاسطح هي اكثر الامكان التي تفقد الحرارة الداخلية في الشتاء وتزيد سخونة المبني في الصيف. الاسطح الخضراء يمكن ان تقلل من كمية الطاقة اللازمة لتلطيف الحرارة داخل المبني وبالتالي الحد من متطلبات الطاقة والتي لها تاثير ايجابي علي نوعية الهواء وتخفيض نسبة تلوثه.

كما ان الاسطح الخضراء ممكن ان تقلل من انبعاثات غازات الاحتباس الحراري وثلوث الهواء المرتبطة بزيادة نسبة ثاني اكسيد الكربون في الجو. وتعتبر محطات الطاقة والمعروف انها مسببة لانبعاثات ثاني اكسيد الكربون تكون الاسطح الخضراء حلا ايجابيا علي تقليل هذه الانبعاثات عن طريق تحويله الي اكسجين مما يساعد علي تحسين نوعية الهواء في البيئة المحيطة.

Different Types of Docks and Its Environmental Sustainability

Like anything else, docks have variations for every function you need. It provides a functional outstretch to an adjacent shoreline. Docks are used for commercial and residential purposes. The different types of docks available in the market range from lightweight to heavy-duty, which depends on the usability of the docks.

Property owners who are planning to install docks need to consider the sustainability of the components. It would be best to use those docks that are not harmful to the marine environment. Let us be conscious of the things we use!

Types of Docks

Each type of docks has its own distinct feature which makes it beneficial for a certain function. When you know the types of docks, you can easily determine the configurations and components of the docks. By then, you can confidently customize the docks based on the features you need.

Removable Docks

Removable docks are the most known and chosen dock for consumers who are living in a harsh climate. They are easy to install and quick to remove. There are two popular removable docks known in the market:

  1. Floating Docks: This removable dock is independent of its stability from the sea bed. It is quite impressive that it only has minimal to no obstruction to the marine life environment. Do not worry. There are anchors to stabilize the float, it is attached to heavy-duty ropes that are tied on the shore.  For those property owners who need an economical, environmentally-friendly, and cheaper dock, floating docks are the answer.
  2. Pipe Docks: For property owners who are looking for the cheapest dock installation and a lightweight alternative, pipe dock is the solution. Pipe docks stand up on legs and sit above the water. Originally, pipe docks are made stationary, but they are customized to have wheels to easily remove them. This type of dock have little impact on the marine environment since it is not submerged in the water.

As we can say, both removable docks have only minimal to no impact on the marine environment. Let us go over the permanent docks!

Permanent Docks

From its name, permanent docks are purposely built to last for years. Permanent docks are stable, they are in a fixed installation. It is expected that these permanent docks can withstand harsh weather and constant use. There are two permanent docks mentioned in this article.

  1. Crib Docks: This dock is termed crib as it is a weighted-down container. The container is filled with rocks or other weights to build an anchor for the dock. These cribs are a solid foundation for a permanent dock. As the anchor is secured, a deck is installed and built on top of the cribs.
  2. Concrete Docks: An alternative option for alternative marine activity is made possible with concrete docks. It is expensive to construct, yet the ideal option for heavy-duty uses. Both foundation and deck are made from concrete to provide a durable and long-lasting structure for decades.

These permanent docks are both installed using heavy equipment, and they are affixed to the sea bed. They may have simple or complex configurations depending on the property owner. But, any configuration of the permanent docks will cause disturbance to the marine environment. Permanent docks are mostly used for commercial properties.

Removable Docks are Environmentally-Friendly

As discussed above, floating docks and pipe docks have minimal to no impact on the marine life environment. Floating docks are a good option to install for waterfront properties. It offers quick access for those who enjoy waterside leisure. Property owners will enjoy their floating dock system for commercial, residential, or marina activities. The floating cubes provide any needs on the shoreline.

These floating dock systems are a revolutionary product. They are made out of high-quality plastic that can endure up to 20 years. You can configure any system you want depending on your application options. You will see the difference in floating docks when you compare it with other types of docks. It has an outstanding lifespan and high-resistance to harsh weather, dangerous chemicals, and punctures.

Lastly, it is easy to maintain floating docks. You only need water and broom to clean it. Refrain from using harsh chemicals, it may go down the water. Its molded polyethylene docks are resistant to oils, salt, and UV ray exposure. Thus, it does not peel, splint, or rot like other docks. Even if it is a low maintenance dock, it is ensured that it has long-term durability and reliable performance.

Are you looking for a reliable floating dock to install in your property? Hisea Dock offers a secure and stabilized floating dock system. You can design any system you would like, their team offers assistance for further inquiries. Moreover, the components they use for their floating docks are sustainable and environmental-friendly.

Why Colleges Should Go for Online Education to Save the Environment

Climate change has been established as an actual, factual event that is changing everyone’s lives, and not for the better. Polar caps are melting, the temperature of the entire Earth is rising, and our oceans are filling with garbage. People across the world are responding in different ways, including reusing products and recycling others, but what about colleges and universities? What can they do to help the environment?

There are several ways that colleges can make a positive impact on the environment, but one of the best ways is to move towards online education. Here’s why:

It Reduces Electrical Use

Electricity is the top service in demand today, along with the Internet. Without it, modern society would cease to function. It’s also what’s eating up an incredible amount of resources on a day-to-day basis.

In cases where the electricity is being provided by a clean fuel source, like hydro, wind, or nuclear power, there isn’t’ as much of an impact on the environment. Unfortunately, there are still many cities that still supply their power through fossil fuels and coal, both of which are incredibly damaging to the environment and only accelerate climate change.

Either way, using less electricity is good for the environment. Online classes mean that students aren’t traversing hallways and sitting in classes. They are, instead, accessing a custom made website from home. As a result, the lights are off in those rooms not in use. That means that the buildings on-campus are using less electricity than before, which is better for the environment.

Online Education Reduces the Use of Heat and Air Conditioning

It’s beyond question that this world is full of different climates ranging from freezing cold to hotter than an oft-mentioned netherworld. People like to stay within a comfortable zone, and so some regions have people turning up the heat while others are putting on their air conditioners.

College campuses know that they’ll be inundated with complaints if their buildings aren’t kept cool on hot days and warm on the cold ones. It’s these very systems that are also contributing to climate change, however, and the best way to take care of it is to be able to turn down those thermostats and turn off those air conditioners.

The best way to do that, without an uprising that is, is to not have students in those classrooms at all so that those thermostats can be turned down. Online classes allow for that to happen.

It Uses Less Paper

The biggest issue affecting climate change is the clearcutting of forests in countries like Brazil for paper production and land for farming. This is something that contributes to the buildup of carbon dioxide in the atmosphere. Why? Because we’re cutting down the one thing that absorbs carbon dioxide and emits oxygen: trees.

Paperless offices are the best approach to reducing the number of trees fallen every year, like the one PaidPaper, the website that provides truthful reviews of the best writing services, has, but many schools require handouts and other materials to be given out, and paper is the default method for their delivery. This situation also means that reviews, an essay, or any other kind of writing usually ends up on paper.

Online classes, however, make using paper almost impossible as all of the materials that students need have to be accessible online. It won’t affect ideas like students need to think like scientists, at all. Essays and tests are done electronically, rather than in person. Online classes mean a paperless class for an essay, reviews, or just to do the best writing they can, and that will save dozens, if not hundreds, of trees every year.

Online Classes Mean No Cars and Buses

Staff and at least some students tend to live off-campus and usually away from the college. For them to get to work and class, they have to have some form of transport.

Yes, some do use bicycles to get to work, but most use another form of transit like a car or a city bus. Both use fossil fuels, and both contribute to negative environmental effects on the world. The best way to negate the effects of fossil fuels is to stop using them.

Again, the best way to accomplish this is to ensure that those students don’t have to get into a car or bus in the first place. Online classes make sure that they can stay at home and save on gas.

It’s Cheaper

What do all of these reductions in electricity, heating, air conditioning, and paper use add up to? Lower budget costs and happier board members, which makes any college administrator smile. The only thing that’s still needed is electronic media and technology, which the university would purchase, anyway.

Those additional funds can be put towards a higher profit margin, or they can be diverted back into the university in ways that save even more money, like improving the insulation in older buildings and the installation of heat-efficient windows.

In conclusion, the benefits of going online for both the college and the environment are many, the disadvantages few. That’s why many universities are getting on board with the idea of online classes.

السياسات المناخية في تونس : ناجعة رغم ضعف الإمكانيات

أصبح التغير المناخي حقيقة واقعة في تونس التي تعاني الأمرين  لمجابهة مشاكل  التصحر وندرة المياه وتدهور الموارد الطبيعية. وبالرغم من إسهامها المحدود في انبعاثات غازات الدفيئة على مستوى العالم، إلا أن أخطار التغير المناخي الواقعة عليها قد تكون عالية التأثير و هو ما يسيل الكثير من الحبر حول مدى نجاعة السياسات المناخية بتونس.

وضعت تونس، وهي رابع دولة عربية قدّمت مساهماتها المعتزمة المحددة وطنيا في مجال خفض الإنبعاثات من الغازات الدفيئة ، تغيّر المناخ في مرتبة متقدّمة على جدول أعمالها السياسي والاقتصادي باعتبارها  البلد الأول في المنطقة الذي ضمّن دستوره الوطني الجديد إقرارا بتغيّر المناخ تفرض من خلاله الدولة  الحق في “بيئة سليمة ومتوازنة والمساهمة في سلامة المناخ بكافة السبل المتاحة”. كما  كانت تونس من أوائل الدول التي صادقت على اتفاقية الأمم المتحدة بشأن تغير المناخ (UNFCCC) في سنة 1993 وبروتوكول كيوتو في سنة 2002. من ناحية أخرى ، إستفادت وزارة البيئة التونسيّة من تواجد فروع لمنظمات  تعنى بالجانب البيئي على أراضيها على غرار المنظمة الألمانية للتعاون الدولي (GIZ) و منظمة فريدريش إيبرت (Friedrich-Ebert-Stiftung) لإنشاء استراتيجية وطنية بشأن تغير المناخ (SNCC)، تأخذ في الاعتبار التحديات والاتجاهات الجديدة لتونس ما بعد الثورة.

كما تبدي تونس  نيّتها العمل بجد  لخفض كثافة انبعاثاتها الكربونية بنسبة 13 في المئة بحلول سنة 2030. هذا ومن المنتظر أن تزداد حصّة الطاقة المتجدّدة في إنتاج الكهرباء لديها إلى 14 في المئة بحلول سنة 2020، و30 في المئة بحلول سنة 2030. هذه المؤشرات الطموحة عزّزها تأكيد رئيس الحكومة يوسف الشاهد  خلال افتتاحه لندوة “تسريع تنفيذ برامج النجاعة الطاقية” يوم الخامس من أبريل نيسان الجاري بأن تونس مطالبة أكثر من أي وقت مضى بتنفيذ إستراتيجيات ناجعة للإنتقال الطاقي قائم على الطاقات المتجددة لبلوغ الأهداف الطاقية والمناخية المرسومة .

في سياق متصل، شرعت تونس منذ عدة سنوات في عملية حقيقية تقليص الاقتصاد القائم على الكربون في خطوة التخفيف من انبعاثات غازات الدفيئة . هذا الأمر تطلب حزمة من الإجراءات الاستباقية طويلة المدى في مجال التحكم في استخدام الطاقة ومع ذلك، هذه العملية تحتاج لمزيد التوطيد و التعزيز.

إلا أن عديد الإشكاليات تطفو على السطح  قد تهدد استدامة هذا التوجه، إذ تفتقر تونس للتمويل اللازم لتغيير نظم إنتاج الطاقة علاوة على غياب واضح للتوعية والإعلام والترشيد سواء لدى العامة أو لدى اصحاب القرار.

هذا الأمر، يجب أن يقابل بتطوير الخطاب الإتصالي للمنظمات البيئية المحلية والعالمية لاتخاذ إجراءات أكثر جرأة على هذا الصعيد. إن نشر المعلومة بشكل مبسط و سلس وتكوين الأطراف ذات الصلة بالشأن البيئي   تعتبر من الثوابت الرئيسية لتنفيذ استراتيجية طويلة المدى. لهذا الغرض، يجب أن تستهدف هذه الإجراءات أساسا  الجهات الفاعلة في الدولة ناهيك عن عامة الناس، أعضاء المجتمع المدني، وسائل الإعلام، الأكاديميين والباحثين وغيرهم وإنشاء قواعد بيانات كاملة عن البحوث والدراسات التي تجرى في تونس أو عنها في الخارج حول قضية تغير المناخ يتم تحديثها باستمرار. في هذا الإطار ، يجب إيلاء عناية خاصة بتوظيف الحلول الطبيعية سهلة التطبيق على غرار القيام بحملات تشجير بالمناطق الصحراوية و حماية التربة من الانجراف و حسن ادارة النفايات. خصوصا مع عدم آمتلاك تونس  للتقنية اللازمة لتطبيق الهندسة الجيولوجية ذات التكلفة العالية والنتائج غير المضمونة.

يُرتقَب أن يشكّل اتفاق باريس الأخير، مع مختلف الفرص المالية والتقنية التي يُتيحها، حافزا مهما لتونس كي تعزّز جهودها في مجابهة التغير المناخي  وهو ما يتطلب آلتفاف جميع الأطراف و تقديم خارطة طريق للتقليل من الانبعاثات وتزيد من مجهودات التكيف لأن إرساء منوال تنموي مستدام ينطلق من هناك.

Saudi Arabia’s Road to Fuel Economy

Saudi Arabia is a private car-oriented society, and has one of the world’s highest per capita fuel consumption in the transportation sector. This is primarily due to lack of efficient public transportation and current fuel subsidy policy. The country is witnessing an escalating demand on its domestic energy needs and it is imperative on policymakers to devise policies for conservation of energy resources and reduction of GHGs emissions in the transportation sector. Adapting energy-efficient fuel standards will help Saudi Arabia country to bridge the gap with the developed countries. The enforcement mechanism for the establishment of Saudi fuel economy standards will lead to achievement of strategic energy conservation objectives.

Energy intensity in Saudi Arabia has set high records reflecting the growth of the economy and the increasing demand on fossil energy in the domestic use and heavy industries operations. Energy intensity in the Kingdom was twice the world average in 2010 and with unbalanced growth between energy use and economy, this should rang the bell for the Saudi government to adapt a bundle of energy policies that curtail the increasing growth of energy demand domestically.

CAFE Standards

Corporate Average Fuel Efficiency standard (CAFE) was first enacted after the Energy Policy and Conservation Act of 1975 in the USA. That policy was due to energy security concerns and environmental objectives. The USA current standard is 27.5 mpg for passenger’s vehicle and 20.7mpg for light trucks. Similarly to the USA CAFE objectives, the Kingdom approach is to reduce gasoline consumption and induce conservation and increasing efficiency of the light-duty vehicles (LDV).The proposed standard mandates require that all new and used passenger vehicles and light trucks either imported or locally manufacture should comply with new fuel standards. The framework for this law to be effective will start by January 1, 2016 and fully phased out by December 31, 2025. The Saudi Energy Efficiency Center (SEEC) and other entities including the Saudi Standards, Metrology and Quality Organization, Saudi Customs, and Ministry of Commerce and Industry have been asked to monitor the implementation of the CAFE standards.

The purpose of the fuel standards is to commit the light-duty vehicle manufactures sell their cars in the kingdom and comply with the Saudi CAFE. This standard has a double dividends from the automobile manufacturer side its incentivize them to introduce the up-to-date efficiency technologies and cut the supply the low-efficient technologies to the Saudi market. The Saudi CAFE standard targets an improving in the overall fuel economy with an average of 4% annually. This would lift up the Kingdom’s fuel economy LDVs from its current level of 12 km per liter to 19 km per liter by 2025.

The Saudi CAFE standard shows a focused strategy to setting long-term standards over the course of a given time frame and its committed efforts to manage both newly imported or used LDVs. According to Prince Abdulaziz bin Salman al-Saud, the Saudi transportation sector consumes about 23 percent of the total energy in the kingdom and about 12 million vehicles consume about 811,000 barrels of gasoline and diesel per day. Moreover, there are 7 LDVs entering the market every year with a forecast to reach 20 million by 2030.

Conclusion

Saudi Arabia’s CAFE standard is a means to stimulate energy efficiency and encourage resource conservation and contribute to the environment. This will enable consumers to save money, reduce fossil fuel consumption and strengthen the Kingdom’s role in the fight against climate change.

Gas Vs Electric Mowers: Are You Ready to Go Green?

There are many factors to take into account when deciding whether to purchase an electric-powered lawn mower or a gas-powered lawn mower. Today there are more options than ever due to advances in technology in both gas motors and batteries. As you weigh your options you should consider the size of your lawn and how you wish to mow it.

compare electric vs gas lawn mower

Gas-powered mowers

Gas-powered motors have traditional gas engines that use gas tanks and oil reservoirs. When operating they produce carbon monoxide, also known as combustion exhaust, which is detrimental to the environment. Also, you have to make sure you have enough gas on hand and that it is the correct grade.

Electric-powered mowers

Electric mowers operate using the same concepts as gas mowers; however, their motors operate using batteries that are charged by connecting them to typical garage outlets, a process which is greener and cleaner. While this does give them many eco-friendly benefits, there are many other factors to consider.

Noise Pollution

Environmental pollution isn’t the only pollution to be considered when comparing gas-powered mowers to electric-powered mowers. There is also the matter of noise pollution to consider. Gas-powered lawn mowers are loud. Electric-powered mowers, on the other hand, purr like kittens by comparison.

You might want to take into account how close you are to your neighbors; or you might want to consider whether you or your neighbors have small children or pets that might be frightened by the sounds of a loud gas-motor.

Maintenance

While the battery used to operate an electric mower is a quieter and cleaner source of power, it does need maintenance. The battery’s posts need to be cleaned from time to time and the battery itself needs to be charged regularly, regardless of how often it is used.

Still, this is much less than the maintenance required for a gas-powered mower that needs to have spark plugs, filters, oil and other components regularly replaced.

Battery life vs Gas-power

How long will an electric-powered mower’s battery hold a charge if it is well maintained? For about an hour, which should be more than enough time to mow a small or mid-sized lawn. If you have a lawn that is larger than an acre, you might want to consider purchasing a riding lawn mower. At this time an electric-powered lawn mower will cost around twenty percent more than a gas-powered lawn mower of similar size, so for an electric-powered riding lawn mower you may be looking at several hundred dollars more than its gas-powered equivalent.

It is up to you, based on the size of your lawn and how often it needs mowed and the current price of gasoline, to do the math in order to determine whether an electric riding lawn mower is cost-effective.

Raw Power

Another point to take into account when considering gas vs electric mowers is that a battery’s charge will drain and so will the mowers power right along with it. In other words, a mower with a fully charged battery will be able to cut thicker grass than it will at a half or a quarter charge; whereas, a gas-powered mower will cut grass with consistent force whether it is fully gassed or it is running on fumes.

If the weight of the machine is an issue, you should know that electric powered mowers are much lighter than their gas-powered counterparts. This is due to the fact that gas-powered engines need metallic parts in order to function properly; while electrical engines can work just as well if certain metal parts are replaced with plastic parts. A lighter mower will be easier to push through well maintained lawns, yet harder to push through overgrown lawns.

Safety

Finally, there is the issue of safety. It takes a great amount of force to bust open a battery. All batteries, from the AAA you use in your television’s remote control to the car battery that can withstand a head-on collision, are designed to stay intact. As long as they do, they are completely safe.

Gas-powered engines, however, require gasoline and oil which are both flammable and combustible, not to mention toxic if inhaled or swallowed (again thinking of small children and pets).

Bottom Line

In conclusion, there are pros and cons to switching to electric and it is up to you to evaluate your individual needs and their requirements as to whether or not the switch is warranted. Remember, for smaller or mid-sized lawns electric mowers are an eco-friendly option; while commercial lawn mowing may benefit more from the power of a gas-powered mower. Whichever you choose, keep in mind that, due to technological advancements, both options offer an efficiency and an ease of use that surpasses mowers of yesterday.

Why Water Pollution Is a Major Worry in the USA: 4 Water Contamination Events and Their Effects

According to a Gallup poll, the majority of Americans are deeply concerned about water pollution. 56% are concerned about drinking water quality and 53% are concerned about the water quality of rivers, reservoirs, and lakes.

Americans have cause for concern. Over the years, there have been multiple water contamination events in the US.

Why Water Pollution is a Major Worry in the USA

Water pollution in the US is actually a growing problem, though it has been a problem for a long time. In the nineteenth century, water quality was improved in many bodies of water thanks to new mining processes and mechanized agriculture.

However, with a lack of regulation, into the twentieth century, rapid urban growth and extensive industrialization resulted in discharges of toxic chemicals, sewage, and other pollutants that affected both surface water and groundwater.

Such problems were not addressed with any sense of urgency until the late twentieth century, and various water contamination events continued to occur.

These have left a lasting impact on ecosystems, water quality, and public health across the nation.

While the implementation of pollution prevention, control and treatment methods are now widely used throughout the country to help ensure water quality is at the safe level determined by federal and state regulations, many bodies of water throughout the US sadly violate those water quality standards.

Let’s take a look at four well-known water contamination events and see what their effects were.

1. The Woburn, Massachusetts Water Contamination

Between 1969 and 1979, industrial solvent polluted the river in Woburn, Massachusetts. The chemicals that contaminated the water were trichloroethylene and perchloroethylene.

Sadly, twelve children in the area who were exposed to the contaminated water developed leukemia and residents saw an increased risk of other types of cancer and birth defects.

2. The Flint Water Crisis

In recent years, there has been an ongoing drinking water crisis in Flint, Michigan. The problem began when the water source was changed from Lake Huron and the Detroit River to the Flint River.

The water has been contaminated with dangerous levels of lead as well as other pollutants. Tragically, that has left many local residents with health issues, including skin lesions, memory loss, vision loss, hair loss, and high lead levels in their blood.

3. The Camp Lejeune Water Contamination in the 1950s – 1980s

At the military base Camp Lejeune, in North Carolina, there was contamination of the water supply for more than three decades.

Between the 1950s and the 1980s, contaminants like trichloroethylene, perchloroethylene, vinyl chloride, and benzene caused military personnel, their families, and civilians on the base to develop symptoms that may be an indication of contamination.

Indeed, the Camp Lejeune water contamination caused many people to develop a number of cancers, such as bladder cancer, kidney cancer, and breast cancer, and other health problems, including birth defects, miscarriages, and Parkinson’s disease.

The scandal has led to many lawsuits. In fact, lawsuits continue to this day

4. The Deepwater Horizon Oil Spill

In 2010, the BP semi-submersible oil rig, Deepwater Horizon, saw an explosion that tragically killed eleven of the crew and displaced the rig from the well at the bottom of the sea. As a result, the oil in the well spread into the ocean.

Bioremediation is a popular method to treat oil spills in seas and on beaches.

Due to the difficulty in sending a probe over 5,000 feet beneath the surface, the well wasn’t capped for a further eighty-seven days, contaminating the water and causing untold damage to the sea life.

The oil spill, which happened in the Gulf of Mexico, saw 3.19 million barrels of oil spread into the ocean, and 1,000 miles of shoreline were impacted.

Trash Talk from Gaza

gaza-garbageSolid waste management is considered to be one of the most severe environmental and civic problems in the Gaza Strip. Solid waste in the Gaza strip consists mainly of household waste, building debris, agricultural waste, industrial waste (mainly from worksites), medical wastes, and wastes from car workshops. Solid waste in the Gaza Strip is dumped in the same landfill without separation except for medical waste, which is dumped separately in the main Gaza landfill site. The solid waste generation rate varies between 0.35 to 1.0 kg/capita/day.

Scale of the Problem

Trash generation in the Gaza Strip varies between 830 to 894 tons/day in cities and villages and from 276 to 300 tons/day in the refugee camps. Local surveys and estimates indicate that household waste accounts for 45 to 50% of the total solid waste, construction and industrial wastes 22 to 25%, and the remaining types (e.g. commercial and institutional) 25 to 30%. Bad practices in the Gaza Strip with the absence of legislation and inspection mechanisms during the occupation resulted in inefficient and inconsistent waste collection services. On many occasions, waste is being dumped in open areas, in various places in the Gaza Strip. And to add fuel to the fire, present landfills in the Gaza Strip are overloaded. This represents a looming danger to the public health and the environment, and particularly to the ground water resources, which are already poor. Not only that but also, hazardous emissions, which are resulted from waste incineration, contain thousands of carbon tones (CO2 gas), causing the temperature to rise. Thus in turn, would be probably the cause of climate change.

Promising Initiative of AYCM Palestine

As regard with potential solutions, Governments and many NGO’s have tried to solve the problem as much as possible or at least alleviate the effects, which are resulted from it. As an example of these efforts, Natuf Organization for Environment & Community Development in partnership with Arab Youth Climate Movement “AYCM” – Palestine,  implemented “ Environmental Leaders toward a Sustainable Community” project which funded by the European Union and the United Nations Development Programme through GEF. During this project, an environmental initiative titled “Separation and recycling of different waste materials into reusable objects” in cooperation with ‘Zero Waste MENA’ team in Gaza.

The initiative was carried out in Shalehat Resort located at the Gaza beach with the participation of vacationers. The main activities included a 10-day awareness campaign, which targeted more than 200 families (about 1,400 people overall) and focused on the impacts of solid waste as well as the importance of sorting and reuse. On the final day, children event with clowns and games was held in order to raise their interest in environmental issues and encourage them to become future environmental leaders.

Recycling-Gaza1In addition, this initiative aims to create a practical model for waste recycling in the Gaza Strip in order to promote the environmental and the general awareness among residents in Gaza. Such processes, as an illustration, contribute to reducing the consumption of fresh raw materials, energy usage, air pollution (from incineration) and water pollution (from landfilling) by decreasing the need for “conventional” waste disposal and lowering greenhouse gas emissions which are considered as the main cause of climate change. As a result, Recycling can be regarded as a good strategy for waste reduction and mitigation of the climate change impacts in the long term.

Conclusions

To conclude, Gaza Strip has encountered from many serious environmental issues, solid waste management, in particular. Such issues may pose detrimental threats to our environment as well as our health. Consequently, I deeply believe that all of us, governments and individuals, should be responsible and careful about our Earth as much as we can. We should work hard together in order to save the whole environment for all of us and for the future generation.

The Concept of Generalised Extended Producer Responsibility (GEPR)

The notion of Extended Producer Responsibility (EPR) has been part of the waste policy for a long time, particularly within the OECD countries. According to the OECD, EPR “aims to make producers responsible for the environmental impacts of their products throughout the product chain, from design to the post-consumer phase” [1]. EPR alleviates the burden of Public Administrations for managing end-of-life products, while -if properly designed- incentivising waste prevention and recycling.

Current Limitations of EPR

After years of implementation it can be argued that Extended Producer Responsibility has not in fact been so extended. Several limitations are common: a) producer responsibility organisations (PRO) managing the EPR do not assume the entire cost of managing the corresponding waste flows, and therefore Public Administrations (through taxes) continue to sustain part of the costs that should be borne by producers (and transferred into prices paid by consumers); b) Through their tariffs, PRO do not sufficiently incentivise recyclability and eco-design amongst individual producers; c) Insufficient transparency makes it difficult for Public Administrations to assess compliance; amongst others. [2]

However, a crucial limitation of EPR (even where this has been most developed) is that it is reduced to a very limited number of products. For example, within the European Union (EU), the application of EPR has only been made compulsory for waste from electric and electronic equipment, batteries and accumulators, and end-of-life vehicles. For other waste streams, EU legislation includes a specific mention to the option for Member States (MS) to promote EPR, such as for packaging waste, and oils, but ultimately the adoption of EPR depends on national legislation. [3]

For most products, EPR simply does not exist. Producers are allowed to put any product on the market, no matter how difficult and costly to manage it is when it turns into waste. This is truly unacceptable.

In some cases, products without EPR are a significant percentage of waste generation, such as for the case of graphic paper, furniture or textiles. In some other cases, these products are not so relevant in weight, but very environmentally problematic and/or very costly to manage, such as: disposable nappies, sanitary pads, cleaning wipes, paint pots, chewing gum, mattresses, cigarette buds, etc. The list could be much longer.

Of course, one could favour the idea of extending EPR specifically to other waste streams, but it seems unlikely that a product-by-product approach manages to cover a broad range of products. In the EU, for example, the Circular Economy Package, which is the most comprehensive effort to update the EU waste legislation in years, includes provisions for the improvement of EPR, but no plans for its extension to additional waste streams.

The idea of this article is to suggest the implementation of the concept of Generalised Extended Producer Responsibility (GEPR), whereby ALL products put into the market -all of them likely to become waste at some point- would be subject to extended producer responsibility.

The Concept of Generalised EPR

Whereas in traditional EPR, there is one or more PRO for each specific waste stream, and producers have to contribute to these PRO, in Generalised Extended Producer Responsibility (GEPR), specific EPR schemes could continue to exist, and maybe a few more would be created, but there would be also general PRO for all those products with no specific EPR schemes:

Public administrations would need to define how the different products contribute to collection and treatment costs (including street cleaning, littering prevention and clean-ups, etc.), and allocate the costs to the different EPR/GEPR schemes. Ultimately only costs related to biowaste –as they derive from endosomatic consumption of energy– should be borne by public administrations and transferred to taxpayers; all other costs should be borne by PRO and transferred to producers, and from them to consumers.

Many details would need to be discussed (links among existing EPR and new GEPR schemes and the corresponding PRO, legal nature, compatibility with other existing or potential economic incentives, etc.).

Of course, implementation of GEPR would entail more paperwork and the need of additional data on impact and cost of the different waste streams. However, this would be less burdensome, faster and cheaper to regulate and monitor than the never ending process of creating one new EPR scheme after another. This would also ensure a consistent application of EPR across a range of different products, which is lacking amongst the different existing EPR schemes.

This approach would be useful in places where application of EPR schemes is already halfway (like in most OECD countries), but also in other geographical contexts, where EPR is not applied or only at a very initial stage.

All in all, GEPR could generalise incentives towards recyclability and cleaner production, particularly if some lessons are learned from past initiatives; and would suppose a much fairer distribution of costs, shifting them from Public Administrations to producers, and ultimately from taxpayers to consumers.
