Implications of the decision by Germany to shut down its nuclear energy reactors in the light of the nuclear disaster in Fukashima Japan .
“With a total of 133 gigawatts of installed generating capacity in place at the start of this year, “there was really a huge amount of space to shut off nuclear plants,” Harry Lehmann, a director general of the German Federal Environment Agency and one of Germany’s leading policy makers on energy and environment, said of the road map he helped develop. The country needs about 90.5 gigawatts of generating capacity on hand to fill a typical national demand of about 80 gigawatts a day. So the 25 gigawatts that nuclear power contributed would not be missed — at least within its borders.
To be prudent, the plan calls for the creation of 23 gigawatts of gas- and coal-powered plants by 2020. Why? Because renewable plants don’t produce nearly to capacity if the air is calm or the sky is cloudy, and there is currently limited capacity to store or transport electricity, energy experts say.”
