I was just looking over old White House transcripts about the "energy crisis" in California in 2001. I'd forgotten that Bush used the Enron-provoked scam to justify not capping CO2 emissions as he'd promised on the campaign trail:
We're now in an energy crisis. And that's why I decided to not have mandatory caps on CO2, because in order to meet those caps, our nation would have had to have had a lot of natural gas immediately flow into the system, which is impossible.
We don't have the infrastructure able to move natural gas.
