Lowered our electric bill in the winters from $400-$500 a month to <$100 by installing a pellet stove instead of using the electric heat pump. Looking to update our AC units (17 years old) with new, more energy efficient/high SEER units. Every time I replace a light bulb I make sure its replaced with LED bulbs. We bought black out shades for the south side of our house to keep the sun out in the dead of the summer. When we replace the AC units I want to replace the thermostats with a Nest or similar "smart" device. Solar just doesn't seem to be beneficial yet. I like the idea but the 30 year payback on your investment isn't ideal.
