There are those in the non-thinking, arrogant, ignorant Big Green movement who demand (they always demand) that everyone (except themselves) stop using fossil fuels. Now. Or the earth is dead in 10-20 years. (It’s always 10-20 years, ever notice that?) And then there are those who kind of believe there may be something to man-made global warming who are looking for ways to reduce carbon emissions realistically. Those in the latter camp, people who actually think rationally, say there is one way to reduce CO2 emissions over the next 30 years: by using more (not less) natural gas.
