The goal of the AGW cult is not to reduce CO2 emissions but to extract money more effectively than ever before. The big government people do not like working alternative energy. Unreliables like wind and solar are expensive enough to rise the prices of carbon based energy which is good news for those who want to earn tax money.
Cheap abundant energy is their worst nightmare. They want dependent people who rely on the government. People are difficult to control if the cost of living goes down. Biofuels were shoot down. Nuclear is destroyed with propaganda and regulations.
