==Small hydropower plants==
===parameters for the determination of a project===
For centuries, power from hydroelectric resources has been captured by man: it is in 1688, that the MARLY machine, build from 14 wheels and pipes, allowed to pump back water from the Seine, located at an altitude of 162m, to supply in the needs of the ponds and fountains of Versailles. Today, to transform hydropower to electrical power, it is possible to construct very large but also small-sized plants. This article lists the parameters to determine small hydroelectric facilities. They have a place in the process of the development of small communities and in the process of [[sustainable development]] because of the economy in terms of CO²-emissions.
