I know that incandescent light bulbs use far more power than cfl's but that excess energy is converted into heat so wouldn't it be the greener thing to do by using those bulbs in the winter until our existing supply of the old bulbs are used since we would not be spending energy to cool the heat coming from the bulbs in the winter?

I had this thought a few days ago because of all the hype of lets throw all the stuff we have away and be green by buying new cars, appliances, light bulbs, everything instead of using an item until it's lifespan is over and then replacing it.

I did however replace all the bulbs in my house after I bought it with CFL's, now I've got 40 old bulbs that still work fine, it just seems to make sense that from a energy standpoint I'd not be wasting it by using these bulbs in the winter
