Photovoltaic energy, batteries and electricity
Here in the UK, sometimes you can get subsidies to upgrade older property, so a few months ago I had a green energy survey done, and then I had a new boiler installed and much thicker loft insulation – the energy savings for these will pay the cost off quickly.
I could also have joined a scheme where electricity from solar panels would be fed into the grid, and the profit from this would repay the cost of the loan over (say) 15 years (I forget the exact details of how it could have worked).
