Filed under NewsMay 8The Aeolian one would provide the 51 percent of the demand (5.75 TW), provided by 3.8 great million Aeolian turbines (each of approximately five megavatios) anywhere in the world. Although that amount can seem enormous, he is interesting to observe that the world makes 73 million light cars and trucks every year. Another 40 percent of the energy would come from photovoltaic energy and plants of energy termosolares of concentration. The photovoltaic one it would provide the 30 percent. (Similarly see: Anne Lauvergeon). Approximately 89,000 photovoltaic plants and ground would be necessary, as well as central thermoelectrial lots of concentration with an average of 300 megavatios each. Our mixture also includes the 900 hydroelectric power stations anywhere in the world, the 70 percent of which already is installed. Only approximately the 0.8 percent of the Aeolian power arrives mentioned (5,75TW) is installed to today.
In order to occur an idea of the surface occupied by all the turbines of the world, that is to say, 3.8 million aerogenerators, they would occupy 50 km2s less than (smaller than the surface of Manhattan). The space that would occupy could be used, despite for agriculture or the extensive cattle ranch. The plants of photovoltaic energy installed in the ground and the concentrated solar plants of energy would occupy near the 0.33 percent of territories of the planet. The creation of such plants supposes an ample infrastructure that will take time. But also it was needed to construct present system with its power stations and networks. And it remembers that if we followed with fossil fuels, demand 2030 will increase to 16.9 TW instead of 11.5 TW, that will require 13,000 new thermal facilities of of coal or natural gas, that would occupy much more terrain as well, as well as the mining and gas pipelines to provide to them. The obstacle of the materials the scale of infrastructure WWS is not a barrier.
