The power sector evolution continues unabated, marked by rapid growth of wind and solar, and a growing shift toward distributed energy resources such as rooftop solar, battery storage, and electric vehicles. Interest in batteries is accelerating as states seek to capitalize the multiple benefits the technology provides to the grid, while the smart grid evolution has unleashed opportunities for electric vehicles to serve as flexible grid balancing resources. State action to promote renewable energy continues in the face of weaker federal environmental regulations. After years of delays, the U.S. offshore wind industry is gaining momentum as several northeastern states have set procurement goals and awarded contracts.
