#DistrictThermalNetworks - well worth investigating everywhere.

The Dutch are implementing district heating based on district heat pumps that recapture waste heat from sewage (a more comprehensive approach would be #DistrictThermalNetworks ) - much more efficient than multiple Air Source Heat Pumps
An advantage for multi unit buildings - potentially a much smaller footprint.
Not sure why this is not being evaluated more in North America

All essential for energy efficiency which will reduce the cost of the renewable energy networks, and reduce cost to the end-user

"keeping a home steady at 75F requires about 30% more power when outside temperatures creep from 95F to 98F." is true for conventional air conditioning/air source heat pumps.
This is why esp. urban communities need district thermal networks that offer ground source heatpump efficiency. It's a lot easier to pump the heat to a 55 or 60 degree heat sink. And in northern climes, you can recover some of that heat in the winter!
