But isn't the point of all of this to get us off of using up nonrenewable resources? Natural gas would only be short term solution.

Actually Natural Gas ( Methane ) is not non-renewable. Methane is generated as a pollutant from most decaying waste. Sewage treatment plants, waste storage silos at places like poultry processing plants, manure from dairy and hog operations, grass clippings, and many more waste streams from our everyday lives produce methane that is essentially wasted.

I saw one project where a dairy farm placed all of its manure into a large pit covered with what was essentially a tent, then piped the methane produced from it to power a portable generator that powered the lights in the barn. Methane converted to carbon dioxide converted to plant material converted to manure converted back to methane. That would be completely recycled carbon leading to power with no net carbon emissions. Biological processes are much more efficient at converting the forms of carbon, so let nature do the work between burning and reproducing the methane.
