It is scientifically established that the discharged water from a coal power plant is chemically hazardous. But, is coal really the answer to affordable and sustainable energy? Global warming is driven by emissions of heat-trapping gases, primarily from human activities, that rise into the atmosphere and act like a blanket, warming the earth’s surface. Elizabeth MacLennan is a fact checker and expert on climate change. As an advanced concept of a changeover from a coal-burning power plant, California is building a new replacement gas-fired power plant in Utah. Methane is 34 times stronger than carbon dioxide at trapping heat over a 100-year period and 86 times stronger over 20 years; roughly 10 percent of all US methane emissions come from coal mining. Toxins in the air have reached "hazardous" levels in Pristina, Kosovo, last week. China is the world's biggest investor in nuclear power -- 49 reactors are up and running, to be joined by 18 more in the coming years -- but the capacity of its planned coal plants exceeds that of .

Coal ash is stored near power plants, both in open-air landfills (“ash pits”) and ponds of water or impoundments (“ash ponds”). As well as being more expensive, it takes a lot longer to build a new coal-fired power plant than it does to build large-scale solar and/or wind farms with battery storage. Coal is polluting the world's oceans and streams with mercury, arsenic and other dangerous chemicals. But when coal is combusted or burned — such as in a power plant, when coal is burned in a boiler; heat from the furnace converts boiler water to steam; and the steam spins turbines to turn generators — it releases a hazardous brew of toxic pollutants into the air, including: Coal’s non-gaseous remnants, coal ash, contain arsenic, lead, mercury, and other heavy metals that are known to cause cancer, developmental disorders, and reproductive issues.

Other harmful pollutants emitted in 2014 by the US coal power fleet include: Most of these emissions can be reduced through pollution controls—sometimes by a significant amount—though many plants don’t have adequate controls installed. In the past, fly ash was released into the air this way, but laws now require that fly ash emissions be captured by filters. The company has said that closing coal plants and adding solar power can save customers more than $6 billion over the next 35 years. Hydropower plants are more restricted in where they can be built. The Union of Concerned Scientists supports continued federal incentives for research for a limited number of full-scale integrated CCS demonstration projects, alongside private sector efforts. "EPA Response to Kingston TVA Coal Ash Spill." The same chemistry that enables coal to produce energy—the breaking down of carbon molecules—also produces a number of profoundly harmful environmental impacts and pollutants that harm public health. Generally, coal fired plants are considered safer than nuclear power plants. According to ACAA, in 2014 U.S. coal power plants generated 129.7 million tons of coal ash.
