For U.S. Energy Secretary Jennifer Graholm, the transformation of Puerto Rico's power grid to solar and other renewable power, after hurricanes wiped it out in 2017 and 2022, is an imperative that goes beyond addressing climate change.
When the lights go out in the U.S. territory, rooftop solar panels backed up with battery storage can provide power to keep medicines like insulin refrigerated, ventilators running and phones charged, potentially saving lives during hurricanes.
