Why Natural Gas Is So Popular During This New Era of Power Generation

Unlike coal and unlike nuclear, natural gas combined cycle plants are actually quite good at ramping up and down to complement those swings in solar and wind power.

And that's really bad for base load generators because their kind of economic proposition is that they have pretty high upfront fixed costs.
