See how much pollution coal plants produce near you

The country's electric grid has transformed over the past two decades. Once the backbone of energy production, coal-generated electricity has dwindled, giving way to natural gas as the top source of electricity generation. Meanwhile, renewable alternatives, though progressing at a more leisurely pace, have made significant strides.

At the start of the century, coal supplied about half of the country's electricity. Today, that share has plummeted below 17%. Nearly 400 plants have shuttered in the past two decades, including a combined 60 retirements in Ohio and Pennsylvania, the states with the most closures. Currently, around 220 coal plants remain operational, with several already slated for retirement within the next decade.
