In simplest terms, energy storage enables electricity to be saved for a later, when and where it is most needed. This creates efficiencies and capabilities for the electric grid—including the ability to reduce greenhouse gas (GHG) emissions. . Energy storage is an enabling technology, which – when paired with energy generated using renewable resources – can save consumers money, improve reliability and resilience, integrate generation sources, and help reduce environmental impacts. It helps maintain the balance between energy supply and demand, which can vary hourly, seasonally, and by location. Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep. . As America moves closer to a clean energy future, energy from intermittent sources like wind and solar must be stored for use when the wind isn't blowing and the sun isn't shining. The Energy Department is working to develop new storage technologies to tackle this challenge -- from supporting. .
