Unfortunately, the price of oil seems to only rise, rarely fall, so I think everyone will have to find ways to reduce. I have started consolidating my messages, so I go out less often, walking more, leaving my car in the driveway.
My DH convinced me two years ago to install a geothermal heating system for our house. We live in the suburbs of Montreal, and paid a substantial amount to be rid of oil heating. Heating with geothermal is cheap, and green! Upfront costs are high, but with the ever increasing price of oil, we think it has a 5 year payback. I have started seeing a few houses in my city converting. Yes, DH was right, it was a good idea.
