Flows through a Dam. Hydroelectric Plants can be responsible for significant Greenhouse Gases. A typical hydroelectric power can generate 0.5 lbs. of CO2 per kilowatt-hour (compared to 0.6-2 lbs. for natural gas burning and 1.4-3.6 lbs. for coal burning). Some hydroelectric power plants can produce 2 to 3 times the greenhouse gases of natural ...

A review of dams and their common materials can be found in Refs. [45], [46]: Arch dams are typically constructed today of mass concrete, with a relatively low cement content, whereas gravity dams are made of loose material. Dams built of loose material are called embankment dams and, in particular, earth dams or rockfill dams.
