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
  • 705 – the number of coal-fired power plants that could be closed through a worldwide shift to CFLs in homes, advanced fluorescents in office buildings, commercial outlets and factories, and LEDs in traffic lights
  • 2,911 – the distance a Toyota Prius hybrid car can drive on the energy saved by replacing one 100 watt incandescent bulb with an equivalent CFL, over its lifetime (New York to San Francisco)
  • 7,000 – the equivalent number of cars’ carbon emissions that would be saved by the action described in the last bullet below
  • 8,000,000 – the number of American homes that could be powered by new wind electric generation facilities which opened worldwide in 2008
  • 48,000,000 – the taxpayer dollars which will be saved over seven years in Los Angeles as a result of replacing the city’s 140,000 street lights with LEDs

    Those statistics are pretty clear cut. I realize you have to spend money to make money, but it would seem that there are tradeoffs with exchanging each and every incandescent bulb with CFLs as it takes an lot more dough to buy all new bulbs when the ones you have are still working and have life in them, not to mention all the carbon wasted getting them from the factory in China to each and every local store around you.

    What still amazes me is that places like gyms have all these spin bikes and treadmills that we walk use for hours on end, and each of those devices could be charging a generator to power the whole device (instead of plugging it in and using grid power) or for more efficient uses, electrify an EV charging station for a patron’s Nissan LEAF. Maybe even the whole gym’s electrical system could be offset by a day of spin classes.

    If we’re going to make it, we have to rethink things from the ground up and stop thinking ways to improve existing systems.
