Edward Norton (awesome actor), Gavin Newsom (dreamy mayor of San Francisco who does some awesome things and some questionable things), and others (who I can only assume to be awesome) are in Washington, D.C. today to speak about how green building policies can save on energy costs and prevent global warming.  From the Select Committee on Energy Independence and Global Warming (awesome committee),

The building sector is responsible for 48 percent of all heat-trapping emissions, and it is estimated that 76 percent of all electricity generated by U.S. power plants goes to operate buildings. As energy prices rise — increasing the costs of cooling, heating and construction — green building has become a popular mantra for homeowners, corporations and environmentalists alike. Yet the numerous definitions of green buildings can lead to confusion, inaction or ineffective policy. As Congress examines all sources and causes of global warming emissions, it must consider how the buildings we work and live in can contribute to reducing the impact of climate change.

Norton, it should be noted, is not being invited to Congress because Fight Club is such a good movie (which it is).  He is a trustee of the Enterprise Foundation, and “works to bring green building practices to low-income housing development.”  Newsom is trying to pass the strictest green building codes in the nation.  The others are doing other things.
