Solar thermal energy

liberation The conventional generations of electricity have stymied the promotion of solar energy because its widespread use is deemed as bad news for the fossil fuel industry. But Africa can no longer play “their” game if we are to pull ourselves out of poverty. We have to start, now by utilizing the vast amount of solar energy that hits the continent’s surface each year. 5 The sun should be the future energy powerhouse if the continent is to attain a better and meaningful development that will

INITIATIVE: A WIN-WIN PARTNERSHIP Boukhalfa Yaici, Cevital Energies Renouvelables MENA Regional Concentrated Solar Power Scale-Up Program Tunis, October 21-22, 2009 Agenda 1. Industrial perspective from Cevital’s side • Current situation • Opportunities 2. Desertec Industrial Initiative: • • • Focus on the activities in the field of power generation on the sun and wind as sources of energy Creating the political framework Benefits for all Industrial perspectives from Cevital’s side Current

Alternative source of energy No other problem is today Traditionally exploited source of energy More than 90% of the world’s energy supply comes from the burning of fossil fuels: petroleum, coal and natural gas. • Petroleum This is the most widely used source of energy. It supplies about 45% of the world’s requirements. However, it is an exhaustible resource, it create environmental problems as removing large quantities of petroleum from under the ground may cause land to sink, it can

Abundant and economical energy is the life blood of modern civilizations, Oil has been dominant in powering almost all machines that move and this makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are clearly ubiquitous and our dependence on oil as fuel and source of energy cannot be over-emphasized. Clearly, we live in the age of oil, but

Clyde Space are based in Glasgow, Scotland and offer cost-effective, off-the-shelf and tailored small satellite power management systems, solar arrays and batteries. Our team has extensive industry experience having worked on over 25 small satellites. Clyde Space is Glasgow’s first indigenous space company and is proud to carry on the Scottish tradition of innovative, reliable engineering

favourite destination IV – Energy in Greece Greece’s comprehensive energy policy, to establish sustainable, competitive, and secure sources of energy Wind is driving growth (= le moteur) in the renewables sector and represents a huge investment potential in Greece . It is estimated that today, 1300 MW of wind farms are operating, while the target is 7,500 MW to be installed by 2020 In future , one of the core components of Greece’s energy profile will be solar. Greece has a superb sun radiation

sector, the thermal sector and finally the part energy. For the electric part the made tasks go of the realization of the post of delivery, power transformer, lighting forces engine by way of the running low distribution, but also the cabling of electric cupboard, the outside tertiary lighting of monuments, industrial buildings and the street lighting. The thermal sector operates the realization of the treatment of the air, of the air conditioning, the classic heating, the solar heating, the
