The U.S. electric grid has virtually no storage space for renewable energy sources such as wind and solar that lower greenhouse gas emissions.

Charles Barnhart, a postdoctoral fellow at Stanford University’s Global Climate and Energy Project, was lead author of a study to calculate how much energy is required to build batteries and other large-scale storage technologies for the electrical grid.

“We calculated how much energy it will cost society to build storage on future power grids that are heavily supplied by renewable resources,” he said. “I would like our study to be a call to arms for increasing the cycle life of electrical energy storage.”
