Be conservative about lighting and smart about personal safety.

Energy conservation is very important, and so is personal safety. If you decide to install the rope lights or icicle lights along the edge of your roof and you've never climbed that far up on a ladder before, it would be wise to hire a professional lighting company to attach them. A few dollars spent on personal safety is quite a few dollars saved on a hospital trip. Also, notice that your January light bill reveals the savings reaped from more conservative lighting. Another thing on the plus side of the ledger. You're a smart consumer; be proud of yourself.
