Hydroelectricity and hydrokinetic turbines

In the province of Quebec, 96% [1] of the electricity production comes from hydroelectricity.

The potential energy of water elevation in an artificial reservoir constitutes the basic energy source of hydroelectricity. Electricity is produced when the water flows through hydraulic turbines down the dam ducts.  

Instead of building a dam on a river, it is possible to install turbine units converting the kinetic energy of flowing water to electricity in a manner very similar as wind turbines do in air. These turbines are named hydrokinetic turbines.

Hydrokinetic turbines may be installed in river or on the seabed to capture tidal energy and many units can be deployed and gathered in favorable sites, within farms of underwater turbines.
