A quick google search tells me that 30.1% of US energy generation comes from coal [1] (at least in 2017), with 62.7% coming from fossil fuels overall.
Unless you’re proposing switching to a ‘cleaner’ fossil fuel source, there’s only so much wind/solar/geothermal can contribute until we see major leaps in the available technologies. Until that time I will continue to view them as a supplemental power source, rather than a primary one.
