Renewable energy has created a hidden infrastructure challenge. While solar and wind power now make up a larger share of the electricity supply, the power grid wasn’t designed to handle them. WSJ asked a power grid engineer to break down the mechanics of renewable energy to explain three ways to make the grid more resilient to disruptions.
