How gravity batteries will help us switch to renewable energy
Gravity batteries might be the answer. The idea sounds simple – when there is plenty of green energy, the batteries use the power to lift a heavy weight either high into the air or to the top of a deep shaft. Then when the power is needed, winches gradually lower the weight, and produce electricity from the movement of the cables.
