  1. U.S. Wind power since 1995 DATA FIT 18% annual growth From EIA website Annual Energy Report: 2005

  2. Hubbert Curve World Coal Production Curve Exponential extrapolation Data Finite resource -> Final answer is 0 H&K fig. 1.11 Exponential growth CANNOT be sustained in a World of FINITE resources!!

  3. Energy Conversions (Table 2.2) digestion thermal Automatically Happens! A key question to consider is with what EFFICIENCY can each of these Conversions be accomplished (Useful energy output/ total energy input)

  4. Inside a Nuclear Power Plant http://science.howstuffworks.com/nuclear-power.htm

  5. Seoinchon (?) Power plant: 57% i.e. for every 1000J of energy that comes into the plant (as natural gas), only 570 J, or only a bit more than half, goes out as useful electricity. In the next chapter, we will see that conversions on down the line are also less than 100% efficient. Conventional power plants may be closer to only 35%-40% efficient!

  6. Energy Losses in a Car http://www.fueleconomy.gov/feg/atv.shtml NOTE: only 13% gets to the wheels and ALL of that goes to thermal energy (eventually) See also: http://www.fueleconomy.gov/feg/hybrid_sbs_cars.shtml

  7. H&K Car Energy Losses

  8. CAFE standards(Corporate AverageFuel Economy)From the D.O.T. http://www.nhtsa.gov/cars/rules/CAFE/docs/Summary-Fuel-Economy-Pref-2004.pdf

  9. CAFE performance standard http://dmses.dot.gov/docimages/pdf102/480389_web.pdf

  10. ITAIPU (Brazil/Paraguay) http://www.solar.coppe.ufrj.br/itaipu.html

  11. http://www.solar.coppe.ufrj.br/itaipu.html ITAIPU (Brazil/Paraguay) 18 turbines, each producing roughly 715 MW 12.9 GW total output! (700 m3/s, effective height ~110m for each turbine)

  14. Residential Electric Power Bill $145.6/1948 kWh = $0.0747/kWh

  15. Commercial Power Costs Energy cost estimates for a project out at IUCF: use (i.e. energy) charge: $3105/(360hr*575kW)=$0.0147/kWh peak use (i.e. maximum power demand) charge: $13.11/kW Why is this different from the residential calculation?

  16. Not all hybrids are created equal! http://www.fueleconomy.gov/feg/hybrid_sbs.shtml

  17. Car Weight vs. Time

  18. Gas taxes in different countries
