In his sort of State of the Union, President Obama said Febr 24:"So I ask this Congress to send me legislation that places a market-based cap on carbon pollution and drives the production of more renewable energy in America. And to support that innovation, we will invest fifteen billion dollars a year to develop technologies like wind power and solar power; advanced biofuels, clean coal, and more fuel-efficient cars and trucks built right here in America." And Obama may even have implicitely referred to the need to be more forward looking to purchase and bank allowances now when he said:"We have lived through an era where too often, short-term gains were prized over long-term prosperity; where we failed to look beyond the next payment, the next quarter, or the next election. Well that day of reckoning has arrived, and the time to take charge of our future is here."
