Now that Barack Obama is the presumptive nominee for the Democratic party, there will be much comparison made between his energy policy and John McCains. According to, www.cutyourfootprint.com, Obama, like McCain supports a cap and trade system where companies are required to pay for the carbon they emit, which essentially acts as a tax against pollution in which the proceeds go to developing greener technologies. Obama is a supporter of coal to liquid technology and ethanol production (which I disagree with) in hopes of achieving a drop in oil consumption by 35% within 20 years. He also favors phasing out incandescent light bulbs in favor of LED energy saving bulbs by 2014.
