there are different systems with different efficiency ratings. However even the worst don't use much water - you don't drink much water in a day.

it goes to the sewer system which needs to be able to take care of things anyway. The amount of waste water through a RO system insignificant - your toilet flushing needs will use more water than your RO drinking water needs. (a typical low flush toilet, though some camping toilets use less)
A reverse osmosis filter will run you $150 for parts - plus install and yearly filter changes. Start with that for costs. I would assume eu costs are similar but that is sometimes very wrong.
If you don't have a sensor then that is cheaper in the short term, but it quickly wastes a lot of energy running when the humidity is under control. For a dehumidifier you need more energy to get lower so the room well generally will be fairly consistent not too low humidity even as outside humidity changes, but you will use a lot more energy than a system that turns off when humidity is good.
there are purely mechanical systems that used to be used. However they have some weird machining requirements so it isn't clear they are cheaper than a digital system (this partially depends on volume - make more and the machining gets cheaper per unit). The digital system is as we already have established is very cheap and lets you put buttons and LEDs on the unit for a few cents more - this is far more valuable to marketing than the possible savings (if any!) from a mechanical control.
Almost no cars, trucks, or tractors are steam based anymore. I believe most ships are ICE as well, not to mention rockets, and animal/muscle power. As such I'd need a very deep analysis of the situation to believe any claim. (deep because in an ICE a large part of the power comes from burning fuel producing steam, so we can start debating how much of an ICE is steam - have fun).
In any case my local electric utility generated more power from wind than all customers used last year, so I can make a good claim most of my power isn't from steam. If your utility isn't in the same situations or close you should be demanding they get with the times.
Tap complete got worse when llm replaced the AST for tabs.
Hr. Somehow this is considered acceptable speach in those formal circles.
If trump could think stratigically a eu-us embargo on china would change china for the better 'ast. But he lets china play us both.
America is not a capitalist society. It is a clasical liberal society. The core concept is you can work for whatever you want and thus obtain it.
Chicago is known as a democrat stronghold. The republicans don't have power to fight anything there.
they do open windows. They also close them. When they do that depends on the situation.
livewise they sit outside at times. They also sit insides.
There are many different hot climates with different situations. You cannot make a blanket statement. And you cannot look at what they do today when ac is common to figrue it out (where at is common)
I have a tuner app, drum machine, and recording apps on my phone. I like to pretend I can play trumpet, mandolin, piano, hammered dulcimer... which means I practice something nearly every day.
