We need to develop electrical storage technologies and smart grid to increase renewable usage above a certain fraction. Plus we need better grid infrastructure. All this is under development, but it is some time off. Natural gas is far, far better than coal in the meantime.
Agree with first bolded, but to fair, as to the second, there are reservoirs, flywheels, compressed air, batteries, and liquefied hydrogen
