Here’s an interesting and fun fact: In just 12 years electricity generated by coal plants has gone from powering 87% of Ohio’s homes and businesses to just 47%. So-called renewables (solar and wind) make up a whopping 3% of Ohio’s electric generation. So what’s replacing coal? Natural gas, which now generates 34% of the state’s electricity. Gas still hasn’t beaten coal, but give it a few more years and it will.
