Directory:Hydroelectric Dams

Hoover Dam

A directory of technologies and resources pertaining to hydroelectric dams.

This page is sparsely populated because this is a well-developed, well-understood technology that doesn't really need explanation.

The down-side to dams include:

Removal of land area and the population (human and other living things) that once resided on that land, as well as the beauties of nature that resided there.
Blockage to natural flow of fish and other river-based life, including beavers.
Build-up of methane from the decomposition of organic matter.

A better alternative to large dams is Run-of-the-River, low-impact hydro technologies that allow for the natural flow of the river.
