 By 2007, Germany accounted for about half the entire world's solar market. Just that one year, 2007, saw 1,300 megawatts, and a megawatt is a million watts, 1,300 megawatts of solar generating capacity brought online just across Germany. For comparison, consider the average generating capacity of each of the last five nuclear power plants brought online in the United States. That capacity is 1,100 megawatts.
