What does it cost to burn a bulb for a year?

Real Estate Agent with Excellent Service Realty

Did you know that a 100 watt incandescent bulb left burning one year would cost about $87 and an equivalent fluorescent bulb of 13watts ( same amount of lumens ) would be $21 for the year. Fluorescent bulbs may cost more ( about $8 ) but they can last for 10000+ hours versus about 750 hours for a regular bulb. I use a fluorescent to work by. It's a daylight fluorescent which has a broader spectrum and is less eye strain. It costs more, but it's worth it. If every American home replaced just one light with an ENERGY STAR light, we would save enough energy to light more than 3 million homes for a year, about $700 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to the emissions of about 800,000 cars. Isn't that amazing !

I've been changing mine as the old ones burn out.  The only thing I don't like is they can';g be used on dimmer switches, or it there a special one made for them?

We switched all our bulbs out for fluorescent ones and the reduction in our electric bill paid for it the first month.  It is amazing.  We also purchased a programmable thermostat for our furnace and air conditioner.  You would not believe the savings.

AR Friends,

I switched all my bulbs to CFL's then changed a couple back. The light was too harsh in some areas. Leaving the light on is the LEAST of most electricity problems because the lighting in the majority of peoples homes only account for a very small portion of their bill.

HVAC and Hot Water usually are the major wallet drainers.

I feel torn between regular old stlye bulbs and the CFLS.  Mostly because the CFLs contain mercury in them and once they get worn out, where else does the mercury go but into our waters and land...and bodies.
