Space shows way to Europe’s renewable energy future   View to Klettwitz, eastern Germany, 80 miles south of Berlin, Europe' s most powerful and biggest area for wind power plants. Solar power     Solar electricity represents a free, abundant and inexhaustible fuel source that already provides energy to hundreds of thousands of people and represents a billion Euro business. The possibilties for expansion are vast: the total energy shone from the Sun to our planet's surface is equivalent to 10,000 times annual global energy consumption. Wind energy     An offshore windfarm. Coastal installations have an output up to 50% higher than land-based winfarms and most future expansion is expected in this area. (Photo: AMEC Border Wind) Hydropower     Hydroelectric power - based on running water turning turbines - is the single largest contributor to the world's production of green energy. The next step     An ERS-2 Synthetic Aperture Radar (SAR) image of Horns Rev windfarm in the North Sea off Denmark. SAR satellite images can be used to accurately estimate offshore wind resources.
