Solid Gravity Energy Storage (SGES) SGES utilizes the same principles as all gravity energy storage systems. The distinction being solid GES uses solid materials, such as concrete. Large blocks of these heavy materials are raised and dropped vertically, storing, and releasing the gravitational potential energy.
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity
