Environmental Impact
Solar power systems generate no air pollution during operation. In California, bird deaths from electrocution or collisions with spinning rotors have increased. Over 30 gold eagles, and 75 red tail hawks have been killed or severely injured due to electrocution or collisions with spinning rotors. Cow manure is an environmental impact because it pollutes the water. This sludge is generally high in silica compounds, chlorides, arsenic, mercury, nickel, and other toxic heavy metals. One costly method of waste disposal involves drying it as thoroughly as possible and shipping it to licensed hazardous waste sites.
