In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.[1] Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls.[2] Aromatic hydrocarbons (arenes), alkanes, alkenes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons.
The majority of hydrocarbons found on Earth naturally occur in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chains.

Hydrocarbons are Substances containing only hydrogen and carbon. Fossil fuels are made up of Hydrocarbons.

Hydroelectric is relating to electric Energy produced by moving water.

Hydroelectric Power is the result of the process of generating electricity by harnessing the power of moving water is called hydroelectricity.

A Hydroelectric power plant is Structure in which the energy of fading or flowing water spins a turbine generator to produce electricity.

A hydroelectric power water use is the use of water in the generation of electricity at plants where the turbine generators are driven by falling water.
