A wind farm doesn’t care about your forecast. It produces what the weather gives it, and someone still has to make that unpredictable output fit into a grid built for steady coal and gas plants. That’s the gap most renewable energy consultants get hired to close. Below are 15 firms doing that work right now, from household names in energy engineering to small teams most people outside the industry have never heard of. So What Are Companies Actually Paying For? Talk to anyone running grid operations and DER integration comes up fast. Rooftop solar, home batteries, EV chargers on every … Continue reading →

A Primer on Biodiesel

By | |
4 Comments

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. This biofuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases. Where available, biodiesel can be used in compression-ignition (diesel) engines in its pure form with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics. It is usually used as a petroleum diesel additive to reduce levels of particulates, carbon monoxide, hydrocarbons and toxics from diesel-powered vehicles. When used as an additive, the resulting diesel fuel may be called B5, B10 … Continue reading →

المغرب، كونها أكبر مستورد للطاقة في شمال أفريقيا، تبذل جهودا مركزة للحد من اعتمادها على الوقود الأحفوري المستورد. وتعتبر الطاقة المتجددة  مصدر موثوق في بلد مثل المغرب العربي التي لديها الاعتماد الكامل تقريبا على شركات الطاقة المستوردة.والمغرب تنفق سنويا  أكثر من 3 مليارات دولار على واردات الوقود والكهرباء في حين انها تشهد نمو الطلب على الطاقة بمعدل 6.5 في المئة سنويا. وفقا لتقرير الوزارة المغربية للطاقة والتعدين، الطاقة الإجمالية المركبة للطاقة المتجددة (باستثناء الطاقة المائية) ما يقرب من 300ميجا وات في عام 2011. وقد حققت الحكومة المغربية بالفعل هدفها المتمثل في توفير حوالي 8٪ من إجمالي الطاقة الأولية من مصادر … Continue reading →

An Introduction to Solar Pond

By | | ,
2 Comments

A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading →

Desertec: What Went Wrong?

A plan to power Europe from solar power plants in Sahara desert, popularly known as Desertec, seems to have stalled, but several large North African solar projects are still going ahead despite local concerns. Where did the Desertec project go wrong, and can desert solar power yet play a role in a democratic and sustainable future? If you use social media, you may well have seen a graphic going around, showing a tiny square in the Sahara desert with the caption: ‘This much solar power in the Sahara would provide enough energy for the whole world!’ Can this really be true? It is … Continue reading →

Solar Energy Prospects in Tunisia

By | | ,

Tunisia is an energy-dependent country with modest oil and gas reserves. Around 97 percent of the total energy is produced by natural gas and oil, while renewables contribute merely 3% of the energy mix. The installed electricity capacity at the end of 2015 was 5,695 MW which is expected to sharply increase to 7,500 MW by 2021 to meet the rising power demands of the industrial and domestic sectors. Needless to say, Tunisia is building additional conventional power plants and developing its solar and wind capacities to sustain economic development. Wind Energy in Tunisia Wind power represents the main source of renewable energy in … Continue reading →

Mega Green Energy Projects in Jordan: How Do We Reduce the Cost?

Leave a comment

Jordan has a huge natural advantage. It gets excellent sunshine all year round and has powerful wind corridors. The country is also in a perfect location to sell clean energy to Europe and Asia. Jordan wants to build massive solar and wind plants, and it plans to create a major green hydrogen network by 2030. However, building these mega projects costs billions of dollars. Because these projects are so expensive to build upfront, the cost of borrowing money from banks is the biggest barrier holding them back. If interest rates and financing costs are too high, the clean energy produced … Continue reading →
