ever heard of concentrated solar power? most people haven't. basically you find an empty patch of ground with clear skies most of the time. cover it with mirrors. super-heat water to some 1000 degrees. store it for days or weeks. convert it to steam when you need it. use the steam to drive turbines to generate electricity. voila! solar power at night. pretty neat, huh? but wait. there's more. the technology is available today off the shelf. and it's cost competitive with coal burning power plants. even without subsidies. or carbon credits. or requiring coal plants to pay carbon penalties.
