Looking at the last week's production, there's a fair way to go before gas is only being used at times of scarcity: https://electricityproduction.uk/from/all-sources/?t=7d https://electricityproduction.uk/from/all-sources/?t=7d Notice how the gas usage cycles up and down, tracking the inverse of solar and wind. But add another 10GW of wind and solar, which is likely by the mid 2020s, and gas won't be used at all pretty often. But it isn't going away completely unless storage gets much cheaper. The biggest challenge now is to start moving residential heating from gas to electric heat pumps. That's a large fraction of our CO2 emissions, and it requires individuals to spend money.
