Outline • Problem and Background • Progress • Cooking Methods • Fuel Sources for Electricity • Programs • Government and U.S. Roles
Rural Energy Crisis • Dependent upon biomass • 1/3 of all consumed energy in the developing areas • Grid extension costly • Rural areas have sporadic energy needs • Require a small amount of energy • Primary areas of concern • China (largest amount of success) • India • Latin America (Brazil) • Africa
Progress • 1970’s • 23 % of rural population have access to electricity • Major concern on energy crisis, not rural areas • 1980’s • 33 % have access to electricity • 1990’s • 44 % have access to electricity • 33% if Chinese efforts excluded
Cooking Methods • All from biomass • Animal dung • Crop residues • Wood Charcoal • Low efficiency • Biomass: 10%, LPG: 65% • Alternatives (move away from raw biomass) • Biogas (animal waste biomass) • Producer Gas (crop residue biomass)
Fuel Sources for Electricity • Diesel-engine generators • Small-scale biopower and hydropower • Photovoltaics • Wind • LPG (only viable in specific situations)
Diesel-Engine Generators • 2-3 times the cost of implemented grid electricity • Less than cost of grid extension • Assists in general energy needs and agricultural needs
Small-Scale Biopower and Hydropower • Biopower replaces the diesel needed • Use producer gas • Improves economic growth • Micro, mini, and small hydropower • Mini is the most common • Unreliable • Droughts, slow river speeds
Photovoltaics • Small-scale electricity • Largest use in Kenya • Joint venture with Shell and Eskom (South Africa) • Leasing methods • >90% collection rate
Wind • Standalone and hybrid systems • Hybrids in densely populated areas • Decrease air pollution • Standalone systems manufactured in house to reduce costs • Hybrids eliminate some diesel fuel • Hybrid technology in industrialized countries • Imports raise the price • Joint ventures
Energy Extension Programs • Chinese National Improved Stoves Program • Largest program to date • Biomass stoves • Kenyan charcoal stove movement • Did not require chimneys • Indoor CO pollution • Bangladesh rural cooperatives • Government supported take-over • Rapid expansion of grid-based electricity
Current Policy • Free-enterprise • Credit/rental program for renewable energy equipment • Private sectors very successful • Government subsidies • Hurts the situation in most areas • U.S. government has little involvement • Technology development
