I find people’s continued use of tumble dryers pretty surprising. The air will do it for free! We have a space-efficient drying rack so we can dry indoors.

Air drying clothes indoor is pretty bad. It is slow, takes space, and leaves textile in a bad state (at least for cotton and wool). Drying outside is good but not possible everywhere and not always. Also things like sheets and towels really should not be left to dry indoor.

> Air drying clothes indoor is pretty bad [because it] leaves textile in a bad state (at least for cotton and wool).

> Also things like sheets and towels really should not be left to dry indoor.

Can you elaborate on both statements? I currently leave everything, including sheets and towels, to air dry indoors.

Why are ACs awkward in Germany?

Because they are power-hungry and everyone knows that. More generally because the climate in central Europe is not like Arizona, Utah, New Mexico, California but hospitable during the summer season without AC. AC makes it more comfortable during hot days but it is still doable without. This is only true for private households. Since 10 years ACs are widely used in a business environment.

Meanwhile during the summer momnths offices in the US turn on the AC to such low temperatures that one needs to put on a sweater.

A while ago I had an idea for a device that has a light sensor on it. The device has in/out for the data cable. It basically overlays a dark image over the feed.

In dark conditions the device darkens the LED output and vice-a-versa for light conditions.

Too many signs are too bright to comfortably look at night.

> I would of course not be in favor of nuclear power. Ok, let's say I could convince you that it is possible to store nuclear waste safely, and show you that building up wind power takes at least as long. Could I convince you then?

No, because of the financial risks involved in constructing, operating and getting rid of them. The costs associated with Fukushima are estimated to be at least 200 billion dollars [1], Chernobyl 235 billion dollars [2]. Even leaving out disaster scenarios: A modern EPR nuclear power plant is at ~1.6 GW [3] at a cost of 11 billion euros, taking a decade or more to build, and about a billion dollars to tear down [4].…

You can't compare the price of a wind park with the price of a nuclear power plant, because the wind park does not offer base load. A wind park without base load is pretty useless. Base load is far more valuable. So if you say a power plant costs 12 billions, it is a steal compared to a two billion wind park. Most people will rather have electricity 24/7 than occasional electricity for 1/6th the price.

Beside that, in another comment you had a long list of things you say is required to make EE feasible. You need to include the price of all these things in your calculation.

The electricity you don't spend is electricity you don't need to produce. We don't really need electricity, we need to do useful stuff with it. Doing laundry with electricity is useful, as is having a computer network. Are massive glowing screens in the middle of the night useful? That would be a very long discussion, but I say no because any local usefulness is outweighed by their negative impact overall. Saving ele…

Actually they are as you need to maintain some base load on a grid.

"Add a few days of storage" This is very non-trivial and will take decades longer than building nuclear power.

Building enough nuclear power plants to power a country also takes decades and is very non-trivial. The quicker we reach 90% carbon-free, the more carbon budget we have left to figure out the remaining 10%. Renewables are the quickest, cheapest way to do that.

>Building enough nuclear power plants to power a country also takes decades

People in Germany said these things 10 years ago too. If Germany had started building nuclear in quantity 10 years ago then they would be coming online now and would get cheaper with each new plant. Instead you will have crippling and deindustrializing power prices for years to come.

Large scale nuclear power with current tech isn't feasible, because of the lack of good uranium sources

This is an insane take, there is plenty of uranium globally. Whoever says otherwise is lying.

Are they more power-hungry than heat? A window unit can be used in the room you sleep in, and if you've done a reasonable job at reducing leakage and insulation , and reducing light ingress (external shutters, etc.) can be pretty efficient. Even in San Diego with the sun bearing down on my flat we managed to have a pretty low load factor on our window AC to keep it around 24-25C at night.
