You’re right to a certain degree. Three things about this: * When you combine renewables together you don’t need to maintain an identical gas backup. Although this will depend on resources at individual locations, some places you will need 100% backup, others substantially less. * Gas is the dominant, cheapest form of electricity in the US and UK, and a very large percentage of the cost of producing a unit of gas electricity is fuel. Even in the worst case scenario of 100% backup, the price that renewables are competing with is the marginal cost of burning fuel to produce the same unit of electricity. Once renewables get below that level it’s cheaper to incur the capital cost for renewables as well as gas, as a combined system, to avoid some of the marginal cost for gas operating on its own. * The Great Global Warming Swindle is an intellectual embarrassment.
