Researchers from Michigan Technological University (MTU) recently published a study, “Potential Lives Saved by Replacing Coal with Solar Photovoltaic Electricity Production in the U.S.” According to the study, ditching coal in favor of solar power would save nearly 52,000 lives in the United States each year. The deaths arise from such medical conditions as asthma, lung cancer, other pulmonary diseases, heart attacks, congestive heart failure, and strokes.
