Um, reality smacked us in the face today when we opened our latest utility bill. Our energy bills have increased 10x since we bought our house. We pay two now - gas and electric. I guess we never realized before how much the apartment paid for us (hot water, washer and dryer). I guess we can write some of it off as paying for two places during 10/1-10/15, but really...we were both a little shocked. I promptly went around adjusting thermostats and turning lights out. Time to buckle down. Plus it's winter, which costs more in general - more lights on longer, more hot water for showers, more heat. What are your favorite tips for keeping your energy bill low?
