Re: But you can't cut energy usage by 1/2 without some extreme lifestyle changes

Electricity usage in air conditioned spaces can see some dramatic changes, though, since the energy used by lighting and appliances is dissipated as heat that must then be removed.

Replace a 500 watt Halogen torchiere with a nearly identical 27 watt fluorescent model and you no longer have to pump that 500 watts out of the space using the A/C.

So, if your A/C unit can pump a watt of heat using a watt of power, switching that one bulb could save about 1,000 watts of electrical energy.

Admittedly that's the extreme case.

But one of my neighbors claims his total annual electricity use has dropped by about one third since he replaced his 20+ year old refrigerator with a new energy efficient model.

Regards,

Dan
