This is incredible- we really can meet the energy needs of the whole world with solar power! It depends entirely on social and political will to do so. Thanks to Sam Lieberman for giving the citation to this paper (see link at end of this description). Its really worth taking the time to read this and consider this real option for our global future and what will be needed to implement it. An area of 3.49 million km² is available for potential locations of solar thermal power plants in the North African countries Morocco, Algeria, Tunisia, Libya and Egypt (DLR, 2005). If a solar electricity yield of 250 GWhel/km² is taken as base for this area, a yield of 872,500 TWhel/y would result. The actual world’s energy demand of 16,076 TWh/y could theoretically be met many times better (BMU, 2004b; Statistisches Bundesamt, 2004). In other words, an area of 254 km x 254 km would be enough to meet the total electricity demand of the world. The amount of electricity needed by the EU-25 states could be produced on an area of 110 km x 110 km. For Germany with a demand of 500 TWh/y an area of 45 km x 45 km is required, which concerns 0.03 % of all suited areas in North Africa (BMU, 2004b). dlr.de/tt/Portaldata/41/Resources/dokumente/institut/system/projects/Ecobalance_of_a_Solar_Electricity_Transmission.pdf
