Free home winterization and free light bulbs: In many areas your power company may provide low income homeowners with a free winterization home inspection and certain power-saving fixes for the home. In other areas they may provide winterization kits for your windows free.
These kits can include: Plastic window and door covers, weather stripping for windows and doors, switch plate insulators, along with compact fluorescent bulbs and other goodies.
Even if you're not low income, in many areas you may be able to pick up free florescent light bulbs from your local home center or drug store. Last year I "bought" 8 bulbs at Home Depot, all I had to pay was the tax! I got 8 light bulbs for around 60 cents! At my local Walgreen's they were doing the same thing. You got the light bulbs free, you just paid the tax they didn't have limit, so I stocked up! The ones at Walgreen's were limited to the 60 watt, but Home Depot had larger wattage bulbs too. The cost of these light bulbs was picked up by our local power company, the cashier just scanned a special coupon into the register. If you are interested, call your local power company or ask at Home Depot or Walgreen's the next time you stop in.
