The United States House of Representatives passed a landmark legislation H.R. 2454, the "American Clean Energy and Security Act," by a narrow margin of 219-212 on 26 June 2009. This bill requires the reduction of nationwide greenhouse gas emissions by 17 percent of the 2005 level by 2020 and 83 percent by 2050 through a "cap-and-trade" program under which companies would buy and sell emissions credits. The bill has more hurdles to cross before it becomes a law.

The idea is to launch giant orbiting solar collectors into space, where there is no night, and beam the power to receivers on the ground, where it is fed as electricity to the grid.
