Wind/Solar/biodiesel all need to be a part of the equation, but if we are actually seriously about doing anything quickly enough to actually make a difference there is only one answer and you're not gonna like it - NUCLEAR POWER - We all need to get over three mile island here. The good news is we can buy up all the old russian nukes that osama is trying to get and burn it up and put the waste somewhere WE control. Seriously, nuclear is the only effective solution in the near term. If something terrible happens, a couple of tens of thousands of people may die, but modern reactors are extremely safe. When was the last nuclear incident, oh yeah North Korea tested a bomb while we were bravely tied down somewhere that has more oil for us to kill ourselvs with. If we dont deal with climate change a couple of billion people will be affected hundreds of millions dying. It is painfully obvious what needs to be done - Nuclear energy as a stepping stone to a hydrogen economy run on renewables with the ultimate goal being fusion. Why arent I in charge?
