> a house with high, quality, modern insulation?

How much is society willing to spend collectively to upgrade our housing stock for this? Not to mention triple-paned windows are not standard by any sufficiently large builder on new construction. Double-paned? Certainly.

Geothermal is great. But in an already built city, it's not feasible to install quickly. There is also a lack of legal framework or precedent in place to heat multiple properties from a single source. I tried very hard to obtain a quote for this and it was well over 50k for a single family home, and nobody would actually do it because of the big city I live in. Want a heat pump too? That's another 25k. Throwing down 100k up-front is not a reasonable request to a typical homeowner.

It's less "spend" as it is "invest". The problem with investment is the cost of capital. But if we're thinking of spending massive amounts of money for nuclear, capital must be very cheap indeed, and we absolutely must consider instead investing that in reducing our need for as much energy.

Geothermal is also a great shift for natural gas utilities. Delivery of weak heat sources to heat pumps is being explored in many areas.

Nuclear is the equivalent of throwing down 100k on a house for a massive custom-drilled ground-source heat pump solution. So in these difficult areas, we need to consider the alternatives.

It's not a reasonable request to a typical homeowner, but if we're looking at a path to a society-wide greener tomorrow, it's worth looking at.

I wonder how much upgraded insulation and geothermal heat pump(/district heating) could be paid for by the cost to build a new nuclear power plant - or even by the difference in cost to build that power plant versus to get sufficient solar and batteries to, in combination with the insulation, generate comparable temperature control.
