Is there anyone on here that is completely free of fossil energy for domestic heating?
I include oil, solid fuel (but not wood), gas (bio gas exempted) and electric generated partly by gas turbine etc.
Yes and no.
We have ground source heating from a vertical bore. It uses electricity from the grid to drive the pump and the controller that handles thermostats and the responses of the valves of the system to ambient conditions. However, we also have solar panels that generate more electricity than is used by the heating pump, water pump (another bore hole) and some of the other electric thingies of the house. Some not all.
We could install a few more solar panels and a large battery to increase (and store) the extra watt-hours we get from the sun - possibly up to the number we use for all our electric things, even the tablesaw and planer-thicknesser. But that would be very costly, especially the battery. And it would make us hostage to fortune (or the weather) if we gave up the grid.
It must be possible to go off-grid but it would take a major investment in the gubbins to provide not just enough juice but a high enough degree of resilience against bad weather or other factors reducing the generation of juice for a significant period. A windmill would help (loadsa money again) but the big cost would be significant storage capacity against a long period of non-generation of juice.
The alternative is to reduce the consumption of electricity. But there would go the woodworking and the electric car. I'd rather find a way to generate and store as much as I want, from renewables only. Perhaps a long lost relative will leave me a wodge? Perhaps the gubbins will get a lot less expensive if government encourages it's use whilst penalising the use of the toxic stuff we all use now?
