Most of human contribution to global warming is as a consequence of greenhouse gasses. This is considerably larger than our actual contribution in terms of thermal energy. By converting to CF globally, we would eliminate the greenhouse gas contribution. In the near term, our contribution to thermal energy would be minimal. The Sun supplies 10000 times more power than we currently use, so our actual contribution is insignificant. Nevertheless wasteful use of CF combined with a growing and wealthier population, would eventually put us back where we are today. So it would be wise to continue along the path of energy efficiency.
