You can do better now. It has been helping people weatherize their houses for over 8 years, and as a result has cut costs so much over revenues that it prepaid all its debts and cut rates 5 times in 5 years, so they are now half the average in the state. This attracted two big factories and helped existing ones expand. In addition, the money saved on energy by consumers becomes purchasing power to keep local businesses thriving. The local economy is doing quite well, thank you.
Individual actions have cumulative effects, and the aggregate consequences can be quite dramatic.
If we in the U.S. spent as much to make our buildings energy-efficient as we do in just one year to protect the flow of oil through the Persian Gulf, we would reduce our energy demand so much that we would no longer have any need to import any oil from the Persian Gulf at all. The amount of artificial energy you use is a measure of how far out of whack you are with natural energy flows. If you are short-sighted you will only pay attention to the immediate price. If you are smart you will calculate the cost over the long run. For some things like refrigerators, the energy cost over its lifetime can exceed the initial purchase price, so the one with the lower sticker price can easily be a trap costing much more in the end.
