MM,
I think that it is pretty accepted, some proof would for sure be volcanos and hot springs. I agree with you and many others, that manipulations with the worlds crust, could result in unwanted geological stress and unexpected natural disasters. I do however think that the risks, compared with other human foolishness, could be less. But if Bush decided to have a go on geothermal, he could achieve almost anything, that is already proved. I would not include geothermal as renewable, only because it is in a technical sense not. It is however maybe the only non-renewable and potentially least damaging source of energy. But then, nothing everything is combined with risks. The reason that I am resentful to many technologies, is that they need very large investments and project size, which puts the large corporations in the driving seat. I will continue to push for KIS (Keep It Simple), because it is the only way to bridge the enormous inequality that we now have. Up till now, the biofuel solutions do offer the best economy and very feasible for the developing countries. I know that it is dangerous for the new "World Order", but I do not care about that.
