How the Hell did anyone get the idea that rating should be done by companies?
It sounds like a perfect job for government. Peak oil is not an energy crisis. It is a liquid fuel crisis.
Companies providing ratings are an example of the Private sector creating Wealth! (literally....)
Government providing ratings imposes an unacceptable Public Sector cost burden imposed upon Wealth Creators. "Any economic unit can emit money. The serious problem is to get it accepted" Hyman Minsky
