Earth2Tech has a nice summary of the features of the bill here http://earth2tech.com/2007/08/05/house-passes-energy-bill/.
I want to disuss what the bill doesn't do. The Bill does not remotely address our dependence on fossil fuel and coal. It basically just nibbles around the edges, establishing programs like the Advanced Research Projects Agency-Energy, for energy research, and requiring the Department of Energy to establish a green building clearinghouse, and providing funds and incentives for alternative fuel research and use. An increase in the fuel efficiency standards for cars, for example, was removed from the bill.
What really needs to happen is large scale, expensive change--a carbon tax, and a cap-and-trade program for emissions. The Federal government needs to create legislation to build the actual cost of environmental damage into each and every energy transaction to effect real change. Now that Democrats have some governmental power, they must push for the large scale change that will really make a difference, as opposed to wasting political capital on band-aid pallitives.
The bill does have some positive aspects--it cuts the $16b subsidy to Big Oil, and it creates milestones for the Federal government to reduce its carbon footprint. But we need to stop playing around, global warming is not a problem that lends itself to partial solutions. It requires large scale political change which will impact large corporate players. The Democrats in Congress do not appear to be ready to think big.
