> I used to think solar and wind power were the best ways to reduce CO2 emissions. But the biggest reduction in CO2 emissionsduring the past 15 years (over 60%) has come from switching from coal to natural gas. That one needs a citation to back it up. It might be true, but natural gas leaks a lot of Methane (CH4) into the atmosphere, which way stronger greenhouse gas effect than CO2. So it might be worse than coal actually.
