Hydroelectric Dams

Paper Summary:

In the United States, hydroelectric dams once provided as much as one-half of all electrical power needs. This paper discusses how since they require so much land, there is also a natural limit to how many new dams can be built and debates their true efficiency as opposed to use of other forms of renewable energy such as fossil fuels.

Outline:
Background and History
Hydroelectric Dams for Power Production and Flooding Prevention in the United States
Evaluating the Contemporary Efficiency and Economics of Hydroelectric Dams

From the Paper:

"Before electricity was harnessed for use as a convenient power source, many early post-Industrial Revolution factories and textile mills relied on water, either for mills driven by the natural power of gravity, or steam engines. Modern hydroelectric dams are complex structures capable of controlling immense volumes of water to reduce the likelihood of natural floods, to provide electric power, irrigate land, and allow open reservoirs and aqueducts to store and deliver water supplies to remote areas far from natural fresh water sources."
