In Robert Zubrin's latest book Energy Victory he argues that liberal, wealthy countries should wean themselves off oil as a prime mover because OPEC and most specifically the House of Saud funds Muslim terrorism and radicalises moderate Muslims.
The money to fund this radicalism comes from oil revenues that come from us in Europe, North America, and Asia. This money is then used to radicalise the Muslims amongst us.
Also, because OPEC sets the price of oil over what the free market would set it at, OPEC prevents developing countries from accessing the cheap energy they need to develop.
A line quoted in this article on Zubrin's book at The Register concerns the "hydrogen economy" - something I've always felt was a canard:
"It’s all pure bunk. To get serious about energy policy, America needs to abandon, once and for all, the false promise of the hydrogen age... Hydrogen, therefore, is not a source of energy. It simply is a carrier of energy... an extremely poor one."
It's nice to have my own opinions vindicated by people who know what they're talking about.
