Yeah my eyes saw Iceland when fuzzy this morning as I was waking up before a good dose of breakfast tea. In true FR fashion I only read the title and saw Iceland who are well off in the energy world.
Iceland is gloomy and solar is not high for them but not zero. They have PVOUTs of 1.5-2 which is not great but with large systems you can power a house with it.
A 20000 watt system would out out 30-40 kWh per day even in Iceland bifacial panels add 40% to that and bifacial work better in winter when the sun is low when they are installed vertically they catch the low rays better than horizontal panels.
A 20kWh system at a PVOUT of 2 would make 14,600kWh per year in a 30 year average.

Ireland like Scotland has wind for days and anyone who has spent anytime in either place knows the wind absolutely howls day and night particularly at night. I grew up in the Midlands UK and we would go to Aberdeen in the regular dad was with BP. It’s windy all the time and look at all the class 5+ red and purple.

You can get a 10kw wind turbine for under $5000 today and in and anywhere in the red let alone purple it’s 30% capacity factor FOR THE YEAR that’s 10,000 watts every hour for 30% of 8760 hours purple is 40% CF Iceland has wind out their backsides and then some.
A ten kw turbine in the red should make 26280 kWh in a year that’s more than 5 times.
[average Irish household uses around 4,200 kWh of electricity per year]
Heating??
In the EU they don’t use MMBTU or Therms it’s kWh or MWh.
[11,000 kWh for gas annually]
So 15,000kWh for both then a 10kw turbine has 3.25 meter long blades. Not large at all and well suited for country side homes and homesteads.
The tech is there it’s how much will is there. I prefer to be grid independent myself I could care less what the grid.does other than to sell power to it. Blackout nope.don’t care I won’t even notice other than one back yard light out that’s behind the inverters specially to show if the grid is up or down.
*Iceland is gloomy = Ireland grrr autocorrect seems to think I only want Iceland now.
