@janrosenow I love my GSHP. However my analysis shows that at least in Ontario the electrons to run my heat pump can’t be supplied in any practical fashion from either our solar or wind resources. The issue is not that we don’t have sufficient renewable potential it is that the heating load falls well outside the peak production for both wind and solar resources.
Similar situation in the UK: solar panels peak production is when the heat pump (#ASHP) needs the least power (just for hot water).
In the #UK, Winters are windy, and harvesting energy from wind would be ideal. Alas, current options aren't suitable: either a massive mast with large blades away from buildings to avoid turbulences (at a huge expense), or nothing.
Installers have so far been reluctant to offer any rooftop options, stating these don't work in practice and end up as net consumers of electricity (some need power to spin up when wind picks up), citing various council-driven initiatives that ended up with wind turbines being sold for scrap after a couple of years.
If someone comes up with a relatively inexpensive rooftop wind turbine capable of operating under turbulent wind input as expected around houses, that would transform domestic energy supply in windy countries like the UK. A huge business opportunity.

Household wind power doesn't make sense: The power per cost scales very well with increasing size, wind speeds are higher above ground etc. @icanbob@janrosenow
