Morocco leans on Renewable Energy
Morocco has no gas or oil gas resources on its territory. Therefore, the realm has to import about 90% of its electricity, totaling about one quarter of its overall importation. Buying energy from oversea is a huge investment for the country and Morocco is now turning to renewable energy to become self-sufficient in terms of energy. The country will soon produce its own energy, mainly through ...

Solar Thermal Power Plants
THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...
