Gas is behind the phase out of coal, partly because gas is cleaner than coal. Never the less, in places like the UK, as coal plants have all been turned off, there is then a requirement to turn off gas as well. However, perhaps first, we need to move away from gas heated homes. This accounts for 38% of the uk gas use (a further 29% is used in gas power plants). We have the means to eliminate both of these gas uses, and need to do so as soon as possible.
