Energy – by the Numbers

Energy facts as reported in the book Plan B 4.0 by Lester R. Brown:

  • 2 – the number of times more expensive is the cost of a CFL bulb compared to an equivalent incandescent bulb
  • 4 – the number of times more energy used by a large screen plasma television, compared to an old-style cathode ray tube television
  • 10 – percentage of the world’s total energy consumption used by appliances in standby mode
  • 10 – the number of times longer that a CFL bulb will last compared to an equivalent incandescent bulb
  • 17 – the number of coal-fired power plants which could be closed if appliance standby mode electricity usage were reduced by just 1 percent
  • 40 – the percentage drop in residential energy use in California between 1975 and 2002 due to stringent building codes (compare to 16 percent reduction in the U.S. for the same time period)
  • 50 – the number of times longer that LED lights last compared to incandescent bulbs
  • 75 – the percentage reduction in electricity use for lighting which can be saved by replacing incandescent bulbs with the new CFL’s
