The U.S. power grid isn't prepared for severe weather. This vulnerability will become more acute as climate change worsens extremes and if the grid doesn't adjust to managing more renewable energy.
This summer is reflective of the tensions extreme weather is bringing to bear on the electricity system. Last month, grid operators in both Texas and California asked people to conserve power, fearful of having to impose outages on high-demand hot summer days. In addition, California energy regulators announced on July 1 they would procure additional energy resources from out of state throughout the summer to ensure the lights stay on.
