1. Korea & the World(7)Alternate Energy & Global Warming 2010. 4. 13 김 병 구 bkkim9@gmail.com

2. This Week in Brief • 키르기스탄 반정부 유혈사태, 과도정부 출범 • 다임러-르노-닛산 전략적 제휴 발표 • 천안함 침몰 다국적 진상규명단 발족 • 미 2010 핵태세 검토보고서 발표 • 과거 약탈 유물 환수 국제회의 카이로 개최

3. Global Warming - Mitigations • Low carbon green growth economy • Energy efficiency, conservation efforts • Introduce carbon tax system • UN climate change initiatives • Kyoto Protocol expires in 2012 • New Protocol in Copenhagen, Dec. 2009

4. Copenhagen Protocol • UNFCCC (Framework Convention on Climate Change) • 192 Member States (S/N Korea 포함) • COP-15 held in Copenhagen, Dec. 2009 • New legally binding protocol by 2012 • Each MS commits to GHG emission level • Major polluters expected to ratify

5. Global Warming Summary • Mechanism: CO2 greenhouse gas from burning fossil fuels • Consequence: climate change, ecology disruptions • National strategy: low carbon, green growth • Post-Kyoto, Copenhagen Protocol • Carbon tax, credit trading • Develop alternate energy sources • Personal strategy • Energy conservation, back to nature

6. Alternatives to Fossil Fuel Energy • Electricity • Present: coal, oil, hydro, nuclear, natural gas • Alternate: wind, solar, tidal, fusion • Transportation • Present: oil, coal • Alternate: electric, hybrid, hydrogen • Process heat, space heating • Present: coal, oil • Alternate: high efficiency, insulation

7. Satellite View of the World at Night

9. 86% of World Energy Produced by Fossil Fuels World Energy Production by Source (not including wood or biomass)

10. Renewable Carbon-free Energy Alternatives • Hydro power • Potential sites already developed • Wind power • Low energy density, site limitations, expansion • Solar power • High capital cost, site limitations, expansion • Tidal power • Very high capital cost, only special sites

11. Hydro Supplies 20% of Global Electricity Production

12. China, Canada and Brazil Lead in Hydroelectric Generation

14. Photo-Voltaic Panels are too Expensive for the Grid

15. Transportation is the Greatest Challenge for CO2 Emissions Reduction Toyota Highlander Hybrid Energy-efficient Gas-Electric Hybrid

16. 10 Personal Conservation Means (1) • Change light bulbs • From regular bulb to fluorescent light • 1bulb effect: 70 kg CO2 savings/year • Drive less • Walk, bicycle, metro subway, public trasport • Every10 km not driving: 4 kg CO2 savings • Recycle more • Home garbage separation for recycle • Half recycle: 1200 kg CO2 savings/year/house

17. 10 Personal Conservation Means(2) • Check your tire air pressure • Proper pressure ~3% better gas milage • 1 liter fuel saving: 3 kg CO2 savings • Use less hot water • Save hot water while shower, washing • Avoid products with a lot of packaging • Resource conservation, reduce wastes • Adjust room temperatures • Summer less air-con, winter 1-2degrees lower • 1,000 kg CO2 savings/year/house

18. 10 Personal Conservation Means(3) • Plant a tree • 1tree: 1 tonCO2 absorption/30year Turn off electric devices • Unused lights, TV, PC, DVD, stereo etc. • Be a part of the solution • www.ClimateCrisis.net

19. Understanding Nuclear Power • Double faces of the atom • Military: Hiroshima, Nagasaki • Peaceful: nuclear electricity, nuclear medicine, agriculture, water, etc. • Pro/cons on nuclear electricity • Pro: no carbon, no pollution, large scale • High-tech infrastructure • Con: nuclear proliferation, waste disposal concerns
