ENV221H1 Lecture Notes - Lecture 9: Sulfur Dioxide, Smog, Peak Oil
Document Summary
15 multiple choice and 4/5 short answer questions. Clean coal technology being developed that reduce environmental impacts of coal energy generation: chemically washing minerals and impurities from the coal, treating the gases with steam to remove sulfur dioxide, carbon capture and storage. *critics claim that money is spent on clean coal rather than research into technologies. Co2 is captures from gases produced by fossil fuel combustion, compressed into dense liquid like state, transported and injected into deep geologic formations. Cons: increase fuel needs of coal fired plant with carbon capture and storage by 25-40%. Considered superior to coal not as dirty. Easily transported through pipes or barrels less pollution. Provides more than 90% of transportation energy. Donuts getting bigger = finding new supplies of. Middle east has oil, south and central america, then north america. Energy security desire to have a safe and secure form of their own energy.
