I explain the pros and cons of geothermal energy in Chapter 12. The technology is not cheap, but it’s extremely clean and reliable. New homes, in particular, can benefit from the installation of geothermal because it’s much less expensive to start a geothermal system from scratch than to retrofit an existing home.
You will need to have access to the right soil conditions, but if you do, this option is an excellent investment, particularly where heating and cooling bills are high year-round. The upfront cost of geothermal equipment is high, but the power bills will be forever low. You’ll not only get lower power bills, but
you’ll be immune from energy price spikes in the future. The value of a home equipped with geothermal equipment is much higher than a conventional home, so you’ll recoup your investment if you decide to sell your home. The higher energy prices go, the more your geothermal system will be worth.
