3. Coal power can create high levels of radiation. A byproduct of burning coal for power, called "coal ash," produces radiation. This ash then settles around the surrounding areas of the coal plant. According to Scientific American, a coal power plant can produce up to 100 times more radiation than a nuclear power plant.
