E.g. Clean Development Mechanism (CDM) allows developed countries to sponsor gas cutting projects in exchange for carbon credits o UK invested in scrubbers for Chinese power stations
Green Strategies Biofuels o Strengths: Provides renewable energy o Weaknesses: Takes away land Deforestation Reduces biodiversity Tree planting Dams o Strengths Provides green electricity Controls flooding o Weaknesses Increased malaria Reduces fish migration Wind farms o Strengths Most effective renewable energy source Generate green electricity o Weaknesses Ugly Takes up space Conserving biodiversity-why? o Ethic o Food o Medicine o Products o Prevent destruction of undiscovered species
Efficiency of fossil fuels-why? o Reduces global warming o Saves money o Increasing population so its necessary o How to: Redesign houses with full insulation and modern boiler systems Green transport Greener power stations Remodel factories with better energy use and processes
Case Studies Biomass - More than 2.5 billion people burn biomass for cooking and heating - NGOs provide cleaner fuels to countries like Sudan and Kenya e.g. liquefied petroleum gas in Sudan. Kenya Community Hydropower Provides lighting, telecommunications and radio to 200 households Saves 42 tonnes of carbon dioxide emissions annually
