Because it's the most efficient, low-cost, and *low-carbon* way of heating Minnesota homes and businesses. And not by a little bit.https://twitter.com/brucenilles/status/1087939524762701840 …

Yes. Have to look at the whole system. 1. Heat pumps will not be operating at 300-400% efficiency during the depths of a Minnesota winter. And 2. It takes more than 3x the BTUs to get the electricity to the customer before its consumed.https://twitter.com/brucenilles/status/1088132164389089283?s=19 …

Geothermal heat pump efficiency is not tied to outside air temperature. In any case, electric grid is not 100% fossil fueled. Thus, fossil fuel consumption is reduced when using heat pumps. As grid decarbonizes, so do all the attached heat pumps, electric vehicles, etc.

Bob, regardless of the efficiency of geothermal pump systems, what is economic benefit of installing these systems vs Nat Gas How many homes across US already have these systems in place? Are you proposing transition through gov subsidies?

Due to volumetric electric pricing, heat pumps effectively "subsidize" fossil fuel use since they pay more of grid delivery costs than they cause. Gas also receives more subsidies from govt... Without inequitable rates and subsidies for gas, heat pumps would be cheaper than gas.
