Saving the Earth via choice of light bulb

Now lets calculate the total cost over the lifetime of the fluorescent bulb assuming a cost rate of 10 cents per KWH.

So, over a 10,000 hour period, the fluorescent bulb has a total cost of $30 and the Incands have a total cost of $82.50.

You just saved 50 bucks as well as 600 KWH of energy.

Clearly always use fluorescent bulbs if you are interested in saving energy and money.
