Global warming does not really matter (and we can't do anything about it). Oil production of almost all countries has already peaked (this is undisputed). The only nations where production hasn't peaked yet (Iraq, Kuwait, Saudi Arabia) are expected to peak in this century. What will happen when we have a global peak? Just look at the state of the current economy and imagine energy costs exponentially rising. There are also economic scenarios that do not predict a huge rise in energy costs, but most (all?) of them predict a shrinking economy. "Green energy" is not the solution to this problem. Yes, it's a replacement for oil (at a much smaller scale), but it does not prevent rising energy costs. In the short-term things like coal will be a replacement for oil and will dramatically increase CO2 emissions. And it's rather unlikely that any country will abide to CO2 emission agreements, when its own energy supply is at stake. I think that we'll see some rather large changes during the next decades. And global warming is only one among many other larger problems.
