> 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

Average American "cardboard house" is better insulated than average European brick or concrete house. Having heavy walls make your house feel "sturdy" but it has nothing to do with energy efficiency. A lot of houses in Europe are just brick or concrete with no additional insulation. In US it's it's rare to have uninsulated houses.

In US more people live in very hot places like Texas and Arizona and people mostly live in single-family houses. Single-family houses obviously takes more energy to cool than "flats". Plus average American house/flat has twice the living area.

I wish the whole world would do this stuff. Light pollution sucks. It's understandable from street lights but other sources aren't as excusable.

Even outdoor lighting is not without problems, especially two recent trends are worrying: - shift from low-pressure sodium lamps (which emit 95%+ of light in the narrow peak, so are a bit easier to filter out in astronomy application, and also don't trigger blue-light neural response in humans, and animals alike) to LEDs (which pollute across the visible spectrum, with plenty of blue light component); - as light effi…

I really missed the sodium lamps after my university "upgraded" to LED. There was something peaceful about the monochrome, and their gentle whine when they got too old.

> 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.

> Winter air tends to be much drier than summer air Where I lived before, that's still 80% (usually 90-95% in summer)

That's relative humidity, not absolute. Absolute humidity has an additional Arrhenius (https://en.wikipedia.org/wiki/Arrhenius_equation) factor. For instance, 100% relative humidity at 40 C is 51.1 g/cm^3, while at 20 C it's only 17.3 g/cm^3.

The South (which means southeast in US parlance) would be cardboard houses in the middle of a literal swamp. The houses in the middle of a literal desert are in the Southwest.

Remember that when you're too hot in an office, there's really nothing you can do about it and you just have to suffer. At least you have the option to do things like put on a sweater when you're too cold. Given that, it seems to make sense to keep the office at the coolest temperature preferred by anyone in it.

I like your logic And like lower temperatures when working. The idea that someone would ask for the whole company to be set at the temperature they want and everyone else wears a jumper quite funny.

My girlfriend strongly believes this comes from "patriarchal society" and specifically a "study" that said office thermostats are set based on an old formula designed in like the 60s and that only looked at how HVAC interacted with men.

I thought the idea that offices set thermostats to an actual standard instead of just whoever cries the loudest or has the most power to be almost laughable, so I looked for the "study" she got it from. Indeed, I don't remember the details, but the governmental bureaucracy involved in recommending HVAC did actually use a formula that was obsolete and didn't consider women. However, there was zero evidence in the study that anyone actually used that formula in consideration of anything.

Your source includes "Electricity for heating, hot water". Maybe this includes households using heat pumps for heating, so this could explain the difference?

Not just heat pumps, but also electric water heaters, which are standard issue for older apartment buildings (those without central hot water).

And also probably the single least efficient source of heat for a home. An apartment using resistive heat instead of a heat pump should not be allowed anymore.

This will chiefly affect commercial billboards and the like, which should not be even allowed to ever emit light (or exist) IMNSHO.

Maine banned billboards a long time ago. One of the best things ever and somehow customers in Maine still find their products and services.

Germany is well able to produce enough energy to sustain its needs. It actually had to produce quite a surplus this year so far to support the European grid as a lot of French nuclear power plants had to be shut down for unscheduled maintenance and due to the drought. But of course, gas is scarce, as Russia is only supplying a fraction of its normal supply, so there is a lot of reason to be energy efficient. Also, as…

> Germany is well able to produce enough energy to sustain its needs > But of course, gas is scarce, as Russia is only supplying a fraction of its normal supply So what energy can Germany actually produce on it's own? Because this just makes it sound like Russia is doing the actual work here.

Depends on what you call "producing energy". Germany is generating enough electricity for its needs. Of course, that depends on importing fuels, like for most other countries, including the US. But it is already able to generate 50% of the electricity by renewables, which is rather high amongst the industrial nations.

Well, in that case we shouldn't improve anything as long as children are starving to death in this world. That should be our only and biggest "bug" to fix. Feel free to recommend another one, but we'll pause all other improvements meanwhile. ¯\_(ツ)_/¯

How about not jeopardizing the economy by ever more constraints and instead investing in better energy technology?

Maine banned all billboard style advertising decades ago. Our economy functions just fine thank you.
