Heat is already the leading contributor to weather-related deaths in the United States. And the increase in extreme heat events puts an extra strain on the country’s power grids, sometimes resulting in blackouts. This can be a deadly combination, depending on where you live.

Recent research aims to show how blackouts during heat waves amplify the number of both heat-related emergency room visits and deaths.
