Solar technologies get way too much attention when, in reality, the benefits today of geothermal energy and putting “geoexchange” systems in homes and businesses are much more compelling. The payback is shorter, and avoidance of greenhouse gas emissions is greater. That said, I kind of know the reason why geothermal gets less respect. For one, investors love patent-protected technologies, and the different approaches to making solar cells and the variety of materials used creates a lot of opportunity in a booming market. Geothermal system are more expensive upfront, and the installation itself is labour-intensive and complex. Most of the cost, in fact, comes with drilling and laying tubes in the ground. The heat pump systems at their core are simple devices — easy to mass-produce but little in terms of intellectual property worth protecting.
