California Gov. Arnold Schwarzenegger
At one point, California Gov. Arnold Schwazenegger was floated as a potential candidate to be President Obama's climate czar. Of all the green Republicans, Schwazenegger might just be the greenest. Recently he burnished his eco-bona fides when he was attacked by right-wing attention junkie Sarah Palin for pushing for a cap-and-trade system, an attack he brushed off by questioning Palin's motives.
In 2006, Schwazenegger signed major legislation that created a market-based program to regulate and reduce greenhouse gas emissions with a stated goal of cutting back to 1990 levels by 2020 and 80 percent below 1990 levels by 2050. California is the most energy-efficient state in the country, so the guy must be doing something right when it comes to energy.
