Wave energy. Wave energy is a form of kinetic energy that exists in the motion of waves in the ocean. Wave motion causes the winds blowing over the surface of the ocean. This energy can be used to run turbines, and there are plenty of places where the winds are strong enough to produce a continuous wave motion.
Energy storage collects surplus energy from the grid during the day when demand is low, stores it, and sends it back to the grid when demand is higher, at night. Energy storage is an important tool to a clean energy future. Currently, the grid uses power plants to supply the grid at high demand points. Adding storage makes communities less
