Prior to 2018 I drove a petrol car, used a heating oil (kerosene) powered boiler to heat my house and butane to power my stove top.
Including electricity and converting all the energy sources to kWh, I used between 50-60 kWh annually. Of that, 5-6 MWh was electricity.
Starting in 2018 and finishing in 2021 I changed to an EV, a heat pump, an induction stove top, added solar PV and boosted insulation. Now I only use electricity to power my home and transport.
I now use 16-18 MWh annually and generate between 5-6 MWh locally.
This is far more energy efficient than I was, which shows just how much more efficient electrical solutions are compared to thermal ones. However it also means that my need for electricity from the grid doubled. And it's actually worse than that because local generation largely offsets my electricity usage in summer but hardly makes a dent in my usage in winter - which is when my electricity demand is highest. So it's more like the grid had to generate 3 to 4 times more electricity in winter.
Now, I like in Ireland where wind generation peaks during winter. And if we'd do offshore wind around the island we'd have a constant source of electricity. So this is all *technically* doable. What we're missing is the political will/vision.
