Q: “...who considers a ground-sourced geothermal heat pump system without thinking about the cost of electricity?”
A: Ignorant liberals who have no idea how the world works.
To answer my own question, I think people who do not think about the cost of electricity when installing a heat pump are the same people who believe that Governments have money and that free stuff costs nothing. These are all forms of magical thinking. Small children, teenagers and liberals all fall into this category.
It is the same small child thinking that Socialism and Communism will work if only done by the “right people.”
