GEOG 101 Lecture Notes - Lecture 10: Nuclear Fuel Cycle, Uranium Dioxide, Thermal Pollution
Document Summary
Fuelwood and other biomass sources provide 10% of the world"s energy: nuclear power provides 6. 3%, and hydropower provides 2. 2% One method diverts a portion of a river"s ow through a pipe or channel, passing it through a powerhouse and then returning it to the river. Another method has water owing over a dam small enough not to impede sh passage, using the water to turn the turbines and then returning the water to the river: hydropower bene ts: Is renewable as long as precipitation falls from the sky and lls river and reservoirs, we can use water to turn turbines. Because no combustion is involved, no carbon dioxide or other pollutants are emitted during the production of hydropower: hydropower negatives: Nuclear power is usable energy extracted from the force that binds atomic nuclei together. Ssion is the reaction that drives the release of nuclear energy in power plantsby splitting apart of atomic nuclei.
