I also want to say how MUCH TIME the florescent bulbs save.

I used to feel like I was changing light bulbs all the time. Some of the places were not so easy, like in stairwells and/or requiring a ladder.

The florescent bulbs really do seem to last for years. And I would save receipts in case you get a dud. I believe most of them are guaranteed for years, often 5-7 years. What I did was just started buying those bulbs instead of the regular ones and whenever one I had going went dead I replaced it with a florescent one.

I'm glad to know about the paint Aaron posted about. Blown-in insulation is a good idea, but it can be pricey. If you are handy you can rent the machine at some Home Depots and do it yourself. It's more important when your home is siding or something not as well insulating as say brick.

Another one I want to get soon is a solar powered attic fan. That seems like a great idea.

They say if your refridgerator is over 10 years old it will be very worth it to upgrade. You will save a lot in your electric bill and it pays for itself quickly. If your fridge is well over 10 years old you will save even more for upgrading.

I've looked some into solar powered roof tiles. They replace a section of roof tiles and are very durable, I think stronger than regular roof tiles. In Germany they have like football fields full of solar panels and Pittsburgh gets a little more sun than there so it's gotta be worth it.

If you have a flat roof and ever need to replace it, it will pay to go with a green rooftop. It insulates better and absorbes water.

In Chigago all new roofs are required to either be green or reflective because of the city heat problems caused by other roofs.
