Electricity Records Explorer Peak months
Electricity grids around the world are undergoing a faster transformation than they have ever seen. A clear way to see this transition in action is to follow when new national highs in generation or share for various fuel sources are set. In some months, dozens of these records are broken around the world, particularly in wind and solar generation.
