Driving through my childhood area up north a few weeks back I was also surprised by the amount of solar going up, for comparison this is an area _north of_ Anchorage/Alaska with less than 3 hours of sun around Christmas, but already by late January (usually the coldest period of the year) there is over 6 hours of sun a day (so with high pressure cold peaks with less wind, the 6 hours probably eases the power bill quite a bit).
An interesting fact about those solar installations was that the panels were mounted almost vertically (probably to avoid being snowed over but also useful in the winter since the sun mostly just shines from the south anyhow).
Northern Germany is much more specialized into wind power, and the south is more solar intensive (though solar is more evenly spread throughout the country than Wind, thanks to ease of installation, and the fact that it still produces tonnes of electricity in the summer).
Solar should be built in Alaska, but wind and hydro is what should be actively subsidized and supported by the government. The market can take care of solar penetration in Alaska if you let it.
Doesn’t Germany now have some of the most costly electricity in the OECD?
For a while there we kept hearing about plug in balcony solar in Germany.
Electricity generation used to be a solved problem, now it’s so bad people want to connect solar on their apartment balcony.
And we’re supposed to believe this is progress?
Some of the deep south get by with electric heat, but they aren't in places where the cold is a typically a legitimate danger to health and safety.
That said most of Europe doesn't heat or cool adequately, Spain and Portugal barely heat their homes in winter and boy it gets cold with 41F/5C nights. Then Germany/Switzerland refuse to use A/C even though the summers get to 95F/35C. Just a few days ago a friend told me he went to the doctor and the doctor passed out during examination from the heat.
ps. Not sure why it's downvoted, I think people read something into my comment that I didn't want to express.
Long-term this is true, and it makes sense to ban gas boilers (potentially with some exceptions): electric heat is significantly more efficient, and can run on renewable energy. But that requires a big investment in infrastructure build-out (heat pumps) which will take decades, and we definitely need to be careful that we handle the transition without screwing people over.
Kitchen, dining, bathroom, three or four bedrooms.
I’ve never seen a split system in a bathroom, but I’ve definitely seen freezing cold bathrooms, or bathrooms with a radiant heater on the wall or heat lamps on the ceiling, which occasionally get left on all day and destroy electricity bills.
Ducted systems almost always extend to the bathroom, and almost always cost AU$15,000 or more to install.
Sure, insulation in ceilings is relatively easy to do, but swapping windows out for double glazed windows with solar thermal reflective film, very expensive.
New homes are much better designed, requiring wall and ceiling insulation and double glazed windows or better.
And yeah, the state of Victoria is still prompting banning new homes even connect to gas. Seems strange when we export around the same volume of LNG as Qatar.
So now we’re back to government subsidies, which routinely prove to drive up the price of whatever is being subsidised, especially at the scale of residential homes.
And your solution still results in the living room / dining room and other shared spaces being inhospitable in winter / summer, so you’ve underestimated the cost at least significantly.
Well we’re certifiably not going that.
No need to wait decades to look at the recent data.
London can’t even work out how to properly ventilate their underground rail network.
The solution is obvious: built nuclear power and refrigeration (heat pumps).
Where it’s too cold either nuclear and heat pumps and / or district heating, or burn gas.
Or people can melt in the summers and freeze in the winters. Because that is exactly what “renewables” have been delivering.
Don't disagree with you there.
> London can’t even work out how to properly ventilate their underground rail network.
This seems unrelated. It's not an energy problem: it's a problem with lack of space in the tunnels and lack of places to build ventilation shafts due to the issue not being considered 100 years ago when the tunnels were built.
> Or people can melt in the summers and freeze in the winters. Because that is exactly what “renewables” have been delivering.
I think this has very little to do with renewables. In particular, solar is perfect for reducing "melt in summer" cases (it's almost always sunny when it's hot) (and I'm not sure where has freeze in winter problems).
The issue seems to be more that weather has gotten hotter, and infrastructure needs to change in response to that (inevitably slow and expensive).
Cold weather kills more people than hot weather. By a huge margin.
People frequently move from cooler areas to areas that have comparatively hotter climates than even the worst (completely fabricated) global warming predictions.
But they rarely do the opposite.
Modern AC units are heat pumps the same box cools in summer and heats in winter, more efficiently than a gas boiler.
What is your stance on heat pumps? Conservatives here, who use the same talking points as you, are against them and they prefer to use oil and gas.
And is 5c a extreme night temperature? Where are you from? I'm not from Europe I think.
Aircon I need a lot more. If anything I'd invest in more of that and more insulation. But a heating installation is just wasted money really.
My point is I think somehow, to create and foster policy that focuses on the well-being of people, using a long-term plan that includes an abundance of everything, including energy. In an ideal scenario you could have your apartment at 18C if you wanted to, but since energy would be near-free and abundant, you could turn it up to whatever you want, guilt-free.
But I'm not from Spain. I have been to Romania a lot and I really hated how much they heated the office during winter. I'd go outside in the -15C in my shirt just to cool off during meeting breaks.
Honestly I'm super comfortable in Spain most of the year. Just 1 month I need a little extra heating and 3 months I need aircon, and a lot of it. But summer is also peak time for solar so energy wise it's not bad.
But I don't consider it poverty at all, really. It's also important not to have too much of a temperature mismatch with the outside because we spend a lot of time outdoors here. And not in airconditioned cars because I don't have (nor want) a car. I'm a lot happier with the freedom that public transport offers.
But not much else.
Earth is an incredibly poor heat conductor, as evidenced by the fact that you don’t have to dig very far, maybe a foot or four, and it’s a fairly constant 14 degrees C, and yet the core is molten lava (rock) and has been that way for billions of years predominantly from latent heat from the planets formation.
So you have to be very careful with heat exchange, lest you exceed the ability of the earth to conduct heat through the rock surrounding the boreholes.
Drilling deep boreholes is difficult as the rock becomes more like plasticine as it approaches temperatures where usefully higher temperatures occur.
Artificial in the sense of using solar energy (direct or electric) to heat mass insulated by earth and later extracting that heat to use (directly in district heating, or indirectly via heat -> electric conversion).
It’s not even a good idea. Water has a greater capacity to store heat than rocks and dirt.
I used my searchfoo and Sage Industries lands in more of the top results [1] [2] (may require careful attention to distinguish between natural and artificial geothermal) As well as an interview [youtube]
There's obviously different methods that have been employed / tried by other companies given [3] which outlines different methods of storage also includes some simple graphics ...

Weirdly all three fall under the description used ( "mass" ) and yet none of the three you mentioned are molten salt or silicon which perform even better than water.
If the point you're making is that you've made little effort to think this through or look to where this has been used, is being used, or at pilot plants going to longer time scales then congratulations, you've convinced me.
