One of the best known clean energy technologies is Hydroelectricity. This technology uses flowing water in a river or dam to drive turbines that generate electricity. All water is returned to its source, and the system as a whole is carbon negative.
Generally, hydro-electric power stations operate on major bodies of water, but it is also possible to design a Micro-Hydro system for an individual building.
When analysing a site for a remote area power supply system one should take into account the potential of a micro-hydro system to provide the power that is needed. If there is a permanent running stream or a permanent dam in a suitable location, power may be available 24 hours a day.
