Between the two I'd prefer coal use over methane. Not that either is better than renewables, but until there's enough supply we'll have to do something. Unfortunately, the energy companies have been saying that for decades while simultaneously dragging their feet. Imagine how far ahead we'd be if Exxon and BP had went toe to toe on wind vs solar.

As long as there's an uptick in renewable market share each year, I'll be content. At least it's being built faster than dirty power.
