Unformatted text preview: What is the problem? What is the problem? Our energy needs fall into two categories: Power Transportation Both are presently dominated by fossil fuels but can be met with a realistic combination of fossil, renewable and nuclear. The pressing issues: Adverse environmental effects of fossil fuel use, particularly the use of coal in power generation is, arguably, the most destructive activity humans can engage in, outside of large-scale war World peak oil (gas and even coal) will be achieved relatively soon oil ~ 2010 (gone by 2065; unc. > 2140) (unconventionals will change gas ~ 2020 (gone by 2040; unc. > 2120) the oil and gas peaks) coal ~ 2050 (gone by 2110) Millions of Barrels per year Millions of Barrels per year World World Peak Peak Oil Oil Energy Used for Power Primarily electricity - to produce light, heat and power Unit: kWhr = thousand watts for an hour U.S. = 9 per kWhr CA = 12 per kWhr NM = 8 per kWhr TN = 5 per kWhr Usually uses some energy source to turn a dynamo - a turbine or a big wheel that turns a metallic shaft inside a stationary metallic wrapping Usually use some energy source to turn a dynamo - a turbine or a big wheel that turns a metallic shaft inside a stationary metallic wrapping wind turning a rotor that turns a turbine Energy Used for Power Primarily electricity - to produce light, heat and power Unit: kWhr = thousand watts for an hour U.S. = 9 per kWhr CA = 12 per kWhr NM = 8 per kWhr TN = 5 per kWhr Usually use some energy source to turn a dynamo - a turbine or a big wheel that turns a metallic shaft inside a stationary metallic wrapping wind turning a rotor that turns a turbine, or falling water that turns a turbine Energy Used for Power Primarily electricity - to produce light, heat and power Unit: kWhr = thousand watts for an hour U.S. = 9 per kWhr CA = 12 per kWhr NM = 8 per kWhr TN = 5 per kWhr Usually use some energy source to turn a dynamo - a turbine or a big wheel that turns a metallic shaft inside a stationary metallic wrapping wind turning a rotor that turns a turbine, or falling water that turns a turbine, or coal, gas, geothermal or nuclear that heats water into steam that turns a turbine Energy Used for Power Primarily electricity - to produce light, heat and power Unit: kWhr = thousand watts for an hour U.S. = 9 per kWhr CA = 12 per kWhr NM = 8 per kWhr TN = 5 per kWhr Usually use some energy source to turn a dynamo - a turbine or a big wheel that turns a metallic shaft inside a stationary metallic wrapping wind turning a rotor that turns a turbine, or falling water that turns a turbine, or coal, gas, geothermal or nuclear that heats water into steam that turns a turbine photovoltaic solar, one of few sources that changes incident solar radiation into electricity through heat without a turbine....
