Right...but at a retail cost of $1.20 (which mean cost to the merchant of about 70¢ and cost to the producer of probably 50¢) the amount of energy would be next to nothing and hardly anything more than a regular light bulb. That ignores the fact that the normal CFL lasts for 5 years and a normal bulb lasts 1 year (meaning you’d have to purchase 5 bulbs). You also would be cutting off (according to the DOE) 18% of your energy use at your home to switch. I saw a 20% decline in energy use and a monthly savings of $30, personally.
I haven't had such luck. I bought 5 or 6 CFLs and only ONE has lasted a reasonable time. It's in the kid's closet where it's used as a nightlight. The rest lasted no better than an incandescent bulb. A couple didn't make 4 months.
I'd like to see the LED lights come along faster.
