Document Summary

These lectures will help you understand: contributions to world energy by fuels that are alternatives to fossil fuels, fundamentals and pros and cons of, hydroelectric power, nuclear energy, biomass energy. Hydropower is clean and renewable: hydropower has advantages over fossil fuels for producing electricity: It is renewable: as long as precipitation fills rivers we can use water to turn turbines. It is clean: no carbon dioxide is emitted. It is efficient: has an eroi of 10:1, as high as any modern-day energy source. Fission releases nuclear energy: nuclear energy = the energy that holds together protons and neutrons within the nucleus of an atom, nuclear fission = the splitting apart of atomic nuclei. Nuclear power delivers energy more cleanly than fossil fuels: advantages of nuclear power over fossil fuels, clean . Helps us avoid emitting 600 million metric tons of carbon each year (8% of global ghg emissions)
