A 100 W light bulb running 4 h/d will cost you $14.61/year. If you
replaced it with a high-efficiency bulb which generated MORE light
(lumens) but used only 25 W you'd be paying $3.65/year and saving
$10.96/year off your electricity bill.

Assuming you run at least 600 W for 4 h/night and morning for lighting
(which is an underestimate for most NA houses) you'd be paying $21.92
with high efficiency bulbs vs. $87.66 with regular incandescent bulbs.
High efficiency bulbs only cost $2-3/ for a good 25 W bulb (equivalent
to 100W+) and last many years longer than regular incandescent bulbs
to boot.

Over five years you'd have saved $328.70 (assuming 600 W for 4 h/day)
with a $12-20 investment!!!

Anyway, that's my environmental plug for the day.
