"The ability to use renewables for the lion’s share of a grid’s supply, coupled with the fact that renewables have been made cheap and are getting yet cheaper, is the basis of a decarbonisation strategy all but universally accepted by those determined to stabilise the climate. Make the power on electric grids emissions-free, cheap and copious. Start electrifying all processes that now require fossil fuels - such as powering cars, or heating homes and steel foundries - where electrification is clearly possible. It does not deliver everything that is needed. But it delivers a lot."
