John McCain's and Barack Obama's energy policies

Barack Obama, and John McCain is the presidential candidates of Untied States in 2008. They both support about renewable energy. Obama have more specific idea about how to work with renewable energy, he say he will spend more money in renewable, this will help us have 5 million green jobs. However, McCain have no targets to do renewable. I know the renewable energy is important for world, because that will decrease that Global Warming effect. So I will agree Barack Obama said. Renewable energy will effect environment that we live, I hope Obama will change our lives.
