Saving Lives and Money: The Potential of Solar to Replace Coal

In a new study published in Renewable & Sustainable Energy Review, a team from Michigan Technological University calculated the cost of combusting coal in terms of human lives along with the potential benefits of switching to solar.
Solar energy has a multitude of
advantageous over coal.
Tens of thousands of Americans die prematurely each year from air pollution-related diseases associated with burning coal. By transitioning to solar photovoltaics (PV) in the US, up to 51,999 American lives would be saved at $1.1 million invested per life.

“Unlike other public health investments, you get more than lives saved,” says Joshua Pearce, a professor of materials science and electrical engineering at Michigan Tech. “In addition to saving lives, solar is producing electricity, which has economic value.”

Using a sensitivity analysis on the value of electricity, which examines the different costs of electricity that varies by region throughout the country, saving a life by using solar power also showed potential to make money—sometimes as much as several million dollars per life, says Pearce.
