> Heat pumps are geothermal masquerading as electric

Air-to-air heat pumps are quite common 1-4 family homes. Even in Nordic countries such as Finland: https://www.sulpu.fi/heat-pump-sales-returned-to-a-growth-pa...

> And the highest number I ever heard for a heat pump was 135% [...] Truth is that electricity is great for kinetic energy but terrible at making heat. Most forms of energy can be transformed into another form of energy at about 50%. Electricity is the weird one where its 90% to motion but only 10% to heat.

Sorry but absolutely not, that's wrong on several levels. First off, in its most basic form of resistive heating, electric heating is already close to 100%. Heat pumps are even better, and I'll just quote Wikipedia

> At a cost of 1 kWh of electricity, they can transfer 1 to 4.5 kWh of thermal energy into a building.
