The Solar Action Energy Society has a page on their website that allows you to e-mail and/or call your local representative to make sure they support and include the important provisions (higher CAFE standards and a commitment to renewable energy) of this legislation. On this page they also have a hyperlink to more info on the bill, as well as an "alert" flyer you can print and hang at work or local coffee shops etc...
Check it out...and please DO SOMETHING! Renewable energy is important and cannot continue to be neglected!
