I'm through with all of these so called "Energy Efficient" appliances, light bulbs, and everything else. 2 years ago I went through our entire house and replaced every incandescent bulb I could find with CFL's. Including all of my outside lighting around my pool. I think I replaced somewhere in the neighborhood of 43 light bulbs total. I didn't notice a dime in savings. This in spite of the fact they claim these new CFL's require only 18% of the energy it takes to power a similar incandescent bulb.
Next we replaced all of our appliances over the last year and a half. Again we went with premium, "energy efficient" appliances. New water heater, new electric stove, new fridge and dishwasher, and we went from a builder grade 4,000 watt electric clothes dryer, to a top of the line gas model. Again, I have yet to see any savings. If there is I sure as hell can't detect it.
The final straw came this last spring when we replaced our original, 13 year old A/C system. We went with a SEER 16 premium Rheem unit that was........you guessed it, "Energy Efficient". My electric bill isn't any less now, than it was before we bought all of this crap. My intention was with retirement coming in another 3 years or so, to get my monthly utilities down as low as possible to minimize my monthly expenditures. Nothing has changed. I was even willing to add more insulation, but the installer said I didn't need it. He told me my attic was one of the better insulated ones he's been in. Moral of story, they can ram all of this so called "Energy Efficient" nonsense. I think most all of it is nothing more than a big sales ploy. My appliances were getting old, and needed replacing. But if I had to do it over again, I wouldn't have spent premium dollars to purchase anything "Energy Efficient". If there in fact is any savings, the stuff will crap out long before it pays for itself. Bill T.
