energy conservation / how to conserve/ save energy

  1. 1. Energy conservation
  2. 2. A VIDEO ON GLOBAL WARMING IT WILL START AUTOMATICALLY JUST WAIT FOR FOR 2 -3 MIN
  3. 3. What is Energy Conservation • Energy conservation refers to reducing energy consumption through using less of an energy service. Energy conservation differs from efficient energy use , which refers to using less energy for a constant service.
  4. 4. WHY U.S. • With 5% of the world’s population, the U.S. uses 26% of the world’s energy. • A U.S. resident consumes 12,000 kWh of electricity a year, nine times the world’s avg. • The average American household emits 23,000 pounds of CO2 annually. • Two billion people in the world do not have electricity. • Just using off the shelf technology we could cut the cost of heating, cooling, and lighting our homes and workplaces by up to 80%.
  5. 5. Electric Energy Conservation in the Home • Art Rosenfeld, Former Commissioner of the California Energy Commission, and pioneer of the Environmental Energy Technologies Division of the Lawrence Berkeley National Lab • Some slides from his aide, John Wilson
  6. 6. California Electricity Consumption
  7. 7. Annual Electricity Use Per California Household (5,914 kWh per household)
  8. 8. Total Electricity Use, per capita, 1960 - 2001 0 2,000 4,000 6,000 8,000 10,000 12,000 14,000 1960 1962 1964 1966 1968 1970 1972 1974 1976 1978 1980 1982 1984 1986 1988 1990 1992 1994 1996 1998 2000 KWh 12,000 8,000 7,000 California U.S. kWh Estimate some of the causes of this 2%/year gain. Each year, the cost of conservation programs, public interest R&D, and standards adds ~1% to electric bills, but cuts 1/2% off the bill. So an investment of $1 in say 1990 saves $.50 per year for 10 to 20 years. Calif annual electric bill in 2004 ~ $32 B, so we’ve avoided ~$16 B of bills, but net saving is only ~$12B/year, i.e. $1000/family/yr.
  9. 9. Average Energy Use per Refrigerator, 1947 to 20091947 1949 1951 1953 1955 1957 1959 1961 1963 1965 1967 1969 1971 1973 1975 1977 1979 1981 1983 1985 1987 1989 1991 1993 1995 1997 1999 2001 2003 2005 2007 2009 0 200 400 600 800 1000 1200 1400 1600 1800 2000 AverageEnergyUseperUnitSold(kWhperyear) Refrigerator kWh per Unit 1978 Cal Standard 1990 Federal Standard 1987 Cal Standard 1980 Cal Standard 1993 Federal Standard 2001 Federal Standard Estimated Standby kWh (per house)
  10. 10. How to save energy?
  11. 11. Tips on saving energy • Unplugging devices when they’re not in use is a simple way to cut your energy costs. • Use a timer to reduce the amount of energy used to light your home. • Use LED bulbs they use 70% less energy an lasts for more than 10 years
  12. 12. Some management programs on saving energy
