The energy in the flowing water can be used to produce electricity. When water flows down a natural gradient turns turbines to generate electricity by constructing dams across rivers. Energy can be extracted from tides by creating a reservoir or basin behind a barrage and then passing tidal waters through turbines in the barrage to generate electricity. The first hydro electric dam was built in late 1800s by Tatas in the Western Ghats of Maharashtra. They use the high rainfall areas in the hills as storage areas
Hydrogen energy
When hydrogen is combusted, it combines with oxygen to form water and release a large amount of energy, which is used in rocket engines.
