Energy Solutions — Gravity Batteries?

Abandoned mines could be a solution to the world's growing energy storage needs. Gravity batteries, also known as pumped hydroelectric energy storage (PHES), use the Earth's gravity to store energy. When there is excess energy, such as from solar or wind power, water is pumped uphill into a reservoir. When there is a demand for energy, the water is released downhill, spinning turbines to generate electricity.
