Here's what I've done to save a few watts. Replaced a bunch of incandescent bulbs with compact flourescents. A few in high usage areas. Actually removed a couple bulbs from circuits that have multiple bulbs that seemed unnecessary. Reduced the winter time thermostat setting on the natural gas forced air furnace with the help of space heaters. Unfortunately, one of the two space heaters I bought has already bit the dust. That was the $39 Honeywell (Kaz) 600W carbon tube radiant heater (like a quartz heater). Very disappointed at the short life of that little sucker, even though I liked the design a lot. Kind of defeats the economic advantages. I would avoid this heater if I were you. Ohters on E-pinions seem to have had similar experiences with this heater. http://tinyurl.com/rbff2 I plan on buying one of those Kill-a-watt power measuring devices: http://www.the-gadgeteer.com/review/kill_a_watt_electric_usage_monitor_review http://tinyurl.com/sx433 Anybody know if this thing is worth the extra money? I couldn't see much difference other than the price: http://tinyurl.com/pg4ts Neither seem to work with 220V.
