"Hydroelectric Energy Production by Country." Grolier Multimedia Encyclopedia. 2008. Grolier Online. 14 Apr. 2008 .

This table gives specific numbers about hydropower's use and distribution throughout the world. It also talked about the potential energy of each country. This table was useful to me because it confirmed details from previous articles that I had read, and it gave me an idea of how much hydroelectricity is produced and could be produced.
