Note: lectures purged periodically so keep up with these! There is “board work” in class, so you need to come. Don’t just rely on Powerpoint notes.

Energy Management North American Oil Consumption Year 1015Btu (1.055EJ, Exa Joules) 1990 40.4 2001 45.9 2010 54.2 2020 64.3 2025 69.3 Source: International Energy Outlook 2003 and US DOE 2003 Note: world oil consumption for 2020 is projected at 250 Quads, North America would be about 28% of that. North America population is 6.7% of world population.

8. Energy Management (2000-2025) Total World Oil Resources US Resources Proved Reserves 1,212 billion barrels 22.45 Reserve Growth 730 billion barrels 76.03 Undiscovered 938 billion barrels 83.03 Includes crude oil and natural gas plant liquids Energy content: 5.8x106 Btu/bbl 1,212 billion barrels is approx. equal to 7030 Quads. We ave. 244 Quads/yr consumption for this time period for a total of 6100 Quads!! That leaves enough to get to 2029 if we could keep the use at 244 Quads/yr. Source:US Geological Survey, 2000

18. GHG Emissions Targets Climate Action Plans Renewable Portfolios GHG Reporting Registries Efficiency Standards Regional Climate Initiatives Responses among the states The costs of climate change for Florida are possibly the highest of any state

19. Florida emissions among US states Florida Overall, Florida ranks 6th among the states in total CO2 emissions Center for Climate Strategies

20. Gains from efficiency & renewables • The Bottom Line • 45% of Florida’s electric power can be met by efficiency savings and renewables by 2023. • Florida generates 0.1% from renewables; national average = 2.3%. • Savings in electricity costs over 15 years could total $84 billion.
