Document Summary

Sources of methane: 40% are from natural source, 60% is from human sources. How: climate mitigation, reducing consumption of electricity not likely, focus on energy efficiency, new ideas for co2 emissions, new energy source, cap and trade: companies are given allowances for co2 emissions. If allowance is exceeded, extra can be purchased from other companies. Cap of allowances is set each year: carbon capture and storage (ccs): developing technology aimed at slowing rate of. Co2 emission by capturing and isolating gas after combustion. Ccs technologies are currently available and can dramatically reduce (by 80-90%) co2 emissions from power plants that burn fossil fuels. Inexpensively isolated, allow for safe and efficient storage and transport: leave little residue behind. Law of conservation of energy: the total energy of the universe is constant. Day 14 notes: energy is conserved, and is neither created nor destroyed, energy is transferred from one form to another (often as heat and/or work).
