It’s often an undiscussed detail, but energy efficiency is not something you want to skimp on, since it can save you money in the long run. Reader Lisa shares, “My husband built our house 20 years ago, and no expense was spared to make it as energy-efficient as possible. We’re in the Midwest, and when we got hit with the polar vortex of -55 degrees with windchill, our heating bill was only $50, while our neighbor’s was almost $400.” If you’re heating your home for six months out of the year, that is over $40,000 in savings over 20 years!
