“But doing so is possible, and best accomplished through mass electrification, the report found.”
And just where is all this clean electricity going to come from?
Coal powered auxiliary generators in everyone's house? You can also use the excessive waste heat to warm your Minnesota house between October and April when the heat pump can't heat your house.
More seriously, if I had to have a heat pump in Minnesota, I would pay extra to install a geothermal heat pump because the air would be far too cold to use as a heat source there. Even in Ohio you will spend too much time with the resistive heater to afford the bill.
In the Midwest, the major renewable source is wind.
I have no knowledge of winds in a Minnesota winter.

There are massive farms raising Unicorns and their excrement will generate all the clean electricity we need.
