Can we produce electricity from gravitational force?


See the power that water falls through the Hoover Dam and Three Gorges Dam (see below). This power is used to create hydroelectricity. Although it is possible to generate electricity using tidal energy, it is much more difficult to make it economically feasible. Hydropower was responsible for 16.6% of world’s electricity in 2015 and 70% of all electricity.
