We had a home energy audit done recently. We learned a lot about our house. Josh, the auditor, checked the exterior walls for insulation. He drills a hole then probes with a wire. I knew most of our walls that were insulated, but he was able to calculate how much was left to do. He checked the water heater and the furnace for the combustion and CO level. We changed all the light bulbs in the house. So for example, instead of each light bulb using 75 watts of juice, it would now be using 15 watts of juice. The exchange of light bulbs was a $300 value in itself! More importantly, Josh is passionate about using energy wisely. I learned how big screen TV’s (unless they are LED) use tons of power, even when they are not turned on! I also learned about a great bathroom fan, that can act as an air exchanger for our whole house. It is in our energy companys’ best interest for us to conserve power, because it is so costly for them to upgrade/expand the regional/national power grid. Hence, they partner up with a non profit organization (Conservation Services Group) to support this service. They also offer no interest loans up to $15,000 (7 years) to take advantage of replacing the “worn out parts” of our house (old windows, furnaces, appliances, increasing insulation) that are costing us more money then we need to spend on power. It all starts with an energy audit, so call 1-866-527-7283, (Masssave.com) and do your self an energy favor.
