I mentioned earlier that I had made a minor improvement at work using compact fluorescent bulbs, but I forgot to note the energy savings in my tally. As a reminder, here's the breakdown:
The two incandescent bulbs I replaced use:
50 watts ÷ 1,000 = 0.05 kWh
0.05 kWh × 8 hrs. = 0.4 kWh/day
0.4 kWh/day × 260 workdays/year = 104 kWh/yr
The new CFL bulbs use:
26 watts ÷ 1,000 = 0.026 kWh
0.026 kWh × 8 hrs. = 0.208 kWh/day
0.208 kWh/day × 260 workdays/year = 55 kWh/yr
Thats a difference of 49 kWh/yr which, considering we are now in April, represents a savings of approximately 37 kWh for 2011. With a vigorous pat on my own back, I now add that total to my tally.
