That sets wind power apart from many of its fellow energy sources. Coal, for example, has been widely been proven to cancer as well as heart and lung problems. According to the National Cancer Institute, people who work in coal manufacturing have a higher risk of developing skin, lung, bladder, kidney, and digestive tract cancer. Byproducts of the industry impact public health, too. Coal- and oil-burning power plants release pollutants like mercury into the air. The neurotoxin makes its way into public water sources, while air pollution causes health problems including asthma and yes, cancer.
