Document Summary
The intergovernmental panel on climate change (ipcc) suggests improved energy efficiency as a key strategy to reduce co2 emissions. Ipcc states in its 2007 report mitigation opportunities with negative costs have the potential to reduce emissions by 6 gt co2eq/yr in 2030. However realizing the energy efficiency gains requires dealing with implementation barriers. Limited access to capital (up front costs) Misplaced, or split incentives where the economic benefits of energy conservation do not accrue to the person who is trying to conserve (golove and eto 1996) There are growing efforts and attention to increasing energy efficiency (ee) Some projects guarantee a payback in less than 2 years. Some projects can improve other variables: quality of life, health, etc. Us electricity generation > 40% of co2 emissions. Household electricity is invisible to the consumer. Electricity is cheap (residential electricity bills are small compared to total household budget) Monthly electric bill: -135 (50 largest utilities); price per kwh: ~11-13 cents/kwh.
