1 Korea & the World(7) Alternate Energy & Global Warming 2011. 4. 26 김 병 구 bkkim9@gmail.com

2 This Week in Brief “Earth Day ( 지구의 날 )” 4 월 22 일 축제 – 1970 년부터 지구 환경, 자원 절약 행사 소말리아 해적 피습 상황 지속 – 최영함 현지급파로 위기 구출 외규장각 도서 프랑스에서 영구 반환 – 1866 병인양요시 프 함대 강화도에서 강탈 – 약탈 문화재 반환의 효시 (?)

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

9 CO2 Emissions = Wealth? Per Capita CO2 Emissions for the World

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

11 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

12 Hydro Supplies 20% of Global Electricity Production

13 China, Canada and Brazil Lead in Hydroelectric Generation

14

15 Photo-Voltaic Panels are too Expensive for the Grid

16 Toyota Highlander Hybrid Energy-efficient Gas-Electric Hybrid Energy-efficient Gas-Electric Hybrid Transportation is the Greatest Challenge for CO 2 Emissions Reduction

17 10 Personal Conservation Means (1) Change light bulbs – From regular bulb to fluorescent light – 1 bulb effect : 70 kg CO2 savings/year Drive less – Walk, bicycle, metro subway, public trasport – Every 10 km not driving: 4 kg CO2 savings Recycle more – Home garbage separation for recycle – Half recycle: 1200 kg CO2 savings/year/house

18 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 1-2 degrees lower 1,000 kg CO2 savings/year/house

19 10 Personal Conservation Means (3) Plant a tree – 1 tree : 1 ton CO2 absorption/30 year Turn off electric devices – Unused lights, TV, PC, DVD, stereo etc. Be a part of the solution – www.ClimateCrisis.net www.ClimateCrisis.net

20 Home work What can I do as an individual to lessen the global worming and climate change?
