Why Are Dams Built?
The reason why dams are constructed is to store water for future use particularly in areas where the rainfall is unreliable. The water stored in the dams may be used for a variety of purposes. During the drier seasons, cities can be supplied with water stored in the dams ensuring that the residents have a constant supply of water.

Energy storage important to creating affordable, reliable, deeply ...
The MITEI report shows that energy storage makes deep decarbonization of reliable electric power systems affordable. "Fossil fuel power plant operators have traditionally responded to demand for electricity — in any given moment — by adjusting the supply of electricity flowing into the grid," says MITEI Director Robert Armstrong, the …
How Energy Storage Works | Union of Concerned Scientists
Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the ...
