If everyone did a little energy conservation, it could result in a fairly significant savings.
I replaced 30 bulbs of varying wattage, from 40 to 100. A compact fluorescent bulb (cf) that provides the same lumens (light, dummy) as a 40 watt incandescent uses 9 watts. The other 31 watts is wasted energy and is mostly converted to heat. For a 100 watt bulb, a 23 watt cf produces more light, the 77 watts again is lost as heat. So in total, I replaced 1940 watts of incandescent bulbs with 449 watts of cf, for a saving of 1491 watts with no loss in lumens. At an average daily usage of 2.4 hours for each bulb times 365 days times 1491 watts, the savings is 1306116 w/hr or 1306 kwh.
The cost of electricity = 5.5 (electr) + 1.04 (trans) + 1.41 (distr) + 0.62 (reg) + 0.7 (debt) = 9.27 c/kwh
For me, that means an annual savings of 1306 x 9.27 = $121.07. The bulbs cost me about $150 total and are supposedly guaranteed for 5 years. So these bulbs will pay for themselves in just over 1 year. Over 5 years, I should save [(121. x 5) -150] = $455. (that's 4 or 5 bj's
)
That's probably typical of most households, with the number of lights in use. In Toronto, say if 100,000 homes did that, it would result in total energy savings of $45,500,000., not to mention a significant reduction in greenhouse gases.
I'm doing my bit, how about you?
