ISLAMABAD (AP) — A new study by the United Nations children’s agency says developing resilient energy systems to power health facilities in Pakistan could avert over 175,000 deaths by 2030.

UNICEF said improved energy resilience would also contribute $296 million to the country’s fragile economy over the next 20 years by reducing maternal, adult and infant mortality.

The study, conducted by UNICEF’s Economist Impact Unit and released Friday, comes as Pakistan is experiencing an intense heatwave that has sickened thousands of people, further burdening the country’s health care system.

Temperatures in various parts of Pakistan soared as high as 49 degrees Celsius (120 degrees Fahrenheit) on Friday. Authorities are urging people to stay indoors, hydrate and avoid unnecessary travel. Demand for power has surged because of the high temperatures, putting a strain on existing electricity sources.
