Expanded deployment of renewable energy technologies can help society mitigate climate change. However, solar and wind energy resources are inherently variable. In this issue of Joule, Hunter and colleagues quantitatively compare a diverse set of energy storage and backup power technologies that can help variable energy resources meet demand. They estimate current technology costs, consider improvement potential, and approximate the uncertainties.
