Health reasons: The American Lung Association estimates that there are 26,000 deaths and 1.5 million cases of acute bronchitis and aggravated asthma caused by small particulates, much of it emitted from coal-fired power plants and from coal ash disposal. They estimate the economic benefits of reduced exposure to particulates alone could reach as much as $281 billion annually. Recently, fine particles have been implicated as a cause of Alzheimer’s and Parkinson’s disease and new research has revealed a troubling link between mental illness and air pollution that seems to particularly effect children.
Economic reasons: Besides reducing health care costs, a switch to renewable energy will help keep our future electric rates low. Wind and solar are falling in cost and are now competitive with energy from coal-fired power plants. Recently AEP/PSO in Oklahoma purchased 800 MW of wind energy saying the cost was now less than building new coal fired plants, and that the purchase will save an estimated $53 million in the first year and even more thereafter. Kansas currently has 27,000 jobs in the clean energy sector. Of those jobs 75% are in wind energy, and are growing at a rate of 2.3% per year. By the end of 2016, 32% of Westar’s retail electricity will come from the wind.
Environmental reasons: Coal is 65 to 95 % carbon. What about the rest? Burning coal releases mercury, chromium, lead, cadmium, arsenic, sulfur oxides, nitrogen oxides, carbon dioxide, particulates, and radioactive isotopes. Burning coal releases millions of tons of pollutants into the air and leaves several hundred million tons behind in the coal ash. Some pollutants stay in the air and others eventually find their way into the water, the food chain, and into us. For comparison, mercury is 100 times as toxic as cyanide, arsenic is 20 times as toxic, and chromium(VI) is 4 times as toxic. These three are also are carcinogenic and accumulate in tissue. Even exposure below the allowed levels increases the chance of cancer over time. The sulfur, nitrogen oxides, and carbon dioxide released by coal combustion harm plants, produce acid rain, and increase the greenhouse gas concentrations. Switching to renewable energy would greatly reduce these pollutants and help preserve the environment for future generations.
Summary: Investing in clean energy protects the environment, reduces death and disease from air pollution, and creates good, local jobs. We must develop policies to encourage the development of renewable energy investments and energy conservation. Our energy needs will best be served by a mixture of traditional and alternate energy sources, and we must be proactive in developing our renewable energy resources.
