I mean I guess this has energy-saving potential, but isn’t it just nice to have some darkness for the environment’s sake? It’s pretty awful living in such brightly lit places that have psychological effects on humans and animals alike. For example in humans light pollution alters our melatonin hormonal levels, so sleep is impacted. It can also thwart animal migration. https://education.nationalgeographic.org/resource…

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.

Not when you consider that it's still heating the room with 3 of those watts. If you asked me to build a house and I threw away more than half of the bricks you'd call me crazy. But when it comes to leds it's called "incredible efficiency". It's only efficient in comparison to the other options, not in any objective sense.
“Efficient” is a relative comparison. Any absolute threshold would be arbitrary anyway
Now sure there are subcategories where 100% efficiency is the maximum theoretical efficiency (like the carnot cycle limit of 37% for heat engines), but that's already misleading info if not specified.

Russia claims it would deliver as much gas as we need if we were to open Nordstream-2 though.
The same Russia invading Europe on its eastern borders? Hasn’t dependence on Russian gas earned some suspicions among ordinary Germans?

The German Green Party was basically founded on anti-nuclear sentiment. The older members see it as their absolute life goal to stop nuclear power. They would rather see everything burn to the ground than change their mind. As long as they are in government any compromise will be difficult. Also, the situation in Germany is much worse than people from the outside think. Our best-case scenarios actually plan for prett…
You make it sound like it's just the greens. In reality, it was a conservative Christian Democrat lead government that decided to get rid of nuclear power. Together with SPD, the socialists. Both are moderate parties and quite representative of the German attitude towards nuclear. There hasn't been a government without either SPD or CDU leading it. No other party has ever supplied a chancellor in post war Germany. An…
Wind and Solar have the drawback of not being a constant or reliable source of energy. Yes, they provide cheap and clean energy but not always when you need it.
Yes, the solution would be to save the energy when you need it BUT we don't have that, yet. I really hope we will figure something out but we need not face reality: The tech is not there yet. It might take decades that we don't have.
This is so frustrating to argue with people. Like, I really like your optimism but we don't have a saving solution. We have some ideas but scaling them up towards the scope that we actually need is not easily done.
I really wish you were right but the facts don't add add.
> However, that will cause industry to respond by investing in reducing their dependency on those energy sources.
Since when do they know that they should be transitioning to other sources? Decades? What have the done? Nothing.
As long there are other countries with cheap gas I am not so optimistic. Yes, some will make the transitions, other will move production to other countries and lot's of them we will simply lose. The next years will be brutal.
Only when the international community actually starts to take climate change and dependence on gas more serious will we see some change.

Not the OP, but indoor drying in winter at least where I live has the issue that (a) it tends to be so slow that the wash sometimes starts smelling stale, (b) it's just extracting heat from the house by evaporation, so it's going to raise your heating bills anyhow, perhaps? (c) you might end up having issues with indoor humidity, such as moldy walls. Heat pump or condensing dryers may well be a better option. Almost…
> you might end up having issues with indoor humidity Winter air tends to be much drier than summer air, so much so that my bath towels dry on the rack in the winter overnight, but may stay damp for a whole day in the summer. That said, water will condense at heat bridges (?)(poorly/not insulated parts of the wall) in the winter, causing mold, if the place is poorly insulated.
Where I lived before, that's still 80% (usually 90-95% in summer)

As household made of 4 persons, with me permanently in Home-Office, have a consumption of roughly ~2300kWh/year, including heating, in Germany. Waschmaschine and Dryer are almost on a daily basis used (the dryer is used less during hot season) If you tend to buy energetic-efficient devices, your power bill is lower, in front of higher costs for the equipment.
~2300kWh/year, including heating And how do you achieve this? What is your energy source for heating?
Re: German digital signage ban prompts confusion
#388Here in Germany, there was recently a leak in the news. It said that a single LED sign consumes as much energy as 10 single households[0]. Of course, the companies don't want to give any official information. That is pretty high for no real value for society in my opinion...

> That is pretty high for no real value for society in my opinion... There is a widespread belief that Advertising serves no purpose to humanity. Advertising is like anything in life: In high doses it is harmful. In lower doses it is useful. If there are regulators in your country that prevent advertisers from making false claims, even better. Advertising has helped me hone onto products and services in my whole life…
It's worse than that. Advertising persuades people to buy ever more stuff they don't need, thereby causing enormous damage to the planet. Advertising is among the top of things we should ban to reduce climate change.

> 1300 kwh/year Wow that is low. In most states in the South average household consumes that per month. https://www.chooseenergy.com/news/article/the-states-that-us...
> In most states in the South average household consumes that per month. That's what happens when you live in cardboard houses in the middle of a literal desert. In Europe more people live in better build houses or flats with centralised heating and no AC. I used 1500kwh last years while working full time from my living room and spent maybe 100 euros on heating
Re: German digital signage ban prompts confusion

Not sure where this number comes from. Statistisches Bundesamt says it's 1,958 kwh. https://www.destatis.de/EN/Themes/Society-Environment/Enviro... Interestingly, for 2 person households they state 3,196 kwh and for 3+ person households 4,919 kwh. Energy consumption scales worse than I expected. I assumed there would be more synergy in shared households.
2 person household without much saving is ~1500kWh in my experience. LEDs and laptop instead of desktop computers lowered these stats quite a lot for me. I'm sure if I bought a newer fridge it would also help.
I use more than that by myself per month. Granted, I have all electrical appliances, heat, and a car, but even without those I have to imagine I'd still use significantly more.
Thank god for being on hydro I guess.
