This Week in Brief G20 재무장관회의 경주 개막 – 국제수지 개선용 위안화 환율 문제 격론 프랑스 정년 연장, 연금 개혁안 파동 – 전국 노동계 파업, 학생 시위 격화 중국 희토류 금속 수출 규제, 세계 시장 95% – 일본 수입국 타격, 전자 hybrid car battery 소재 칠레 광부 33 인 700m 지하 구조 인간승리 – 69 일만에 기적적 생환, Mision Cumplida Chile!

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

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
15
Photo-Voltaic Panels are too Expensive for the Grid

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
