Power plants that burn coal for the production of energy pollute the air and ultimately the river. Alabama Power Company’s Gorgas Steam Plant on the Mulberry Fork, Miller Steam Plant on the Locust Fork, and the Greene County Steam Plant on the lower Black Warrior River are old plants that need to have their pollution controls updated.
Jun 15, 2016 than 200 coal fired power plants nationwide have even with outdated equipment. Since many power plants have installed pollution trucks or other impacts of mining.
In a coal power plant, water is used for washing coal, circulating in the boiler furnace to produce steam and cooling of equipment. The dust from coal cleaned water contaminates groundwater. The hot water, if let out into water bodies without cooling, causes a rise in temperature and affects aquatic flora and fauna.
With data and modelling from almost 8,000 coal power plants, researchers present the most comprehensive global picture to date of climate and human health impacts from coal power generation.
Power plant operators thus have an economic interest in keeping their plants running for a long time. The best option is therefore to not build any new coal power plants. From a health and.
