Older cars actually followed good practices about the interior and gauges lighting. All used red, yellow or orange backlights to not impact your night vision.
Now cars are full of bright white screens…

Then I don’t know why, but I am sure over 30% of heat in my house escapes through the roof.
Yeah I lived in flats before, it’s a totally different story, unless your flat is on the last floor or on the corner there is not much heat loss assuming your neighbors also use the heating.
Invoice from yesterday for December 2023. I used 201 m3 of gas, calculated by provider as being equal to 2224kWh of power for which I paid 682.81 PLN (157 € to be exact) in total including taxes and surcharges. So 3.397 PLN or around 0.78 EUR per m3.
December was one of the coldest months this season. Last year I used maximum of 250 m3 per month which happened to be January/February. This then exceeded 200€
This includes both warm water and heating using low-temperature floor heating. Current thermostat settings give me 22C on the base floor and 20C on the first floor (where most heat escapes, obviously). I also have mechanical ventilation with recuperation.
Shit’s expensive.
With current prices of electricity, the same heating power with perfect constant COP of 3 (not possible with December temps for air heat pump) would cost me 666 PLN. (Nice). How can I offset the cost of installing it in the first place LOL.
Lucky you. 175 square meters, 25cm styrofoam on walls and 30cm rock wool on ceiling and I pay 200€ per month in winter for gas heating in Poland. Solar panels are not economical in current regulations and billing rules have changed so those with heat pumps pay at least twice us much in coldest months.
We are fucked from every angle.
Ah yes, Harold :) I forgot

Power draw for cellular tower equipment has become a major concern and product differentiator for mobile operators. I work in telco sector.
AFAIK Apple develops their modem in Germany. The initial effort to get into this market is tremendous. After that it’s incremental improvements, but you must start somewhere.
Hah look at the downvotes, you can’t have civilized discussion these days.
Your last paragraph and my last sentence is the whole culprit for me. The money I have to pay here for good heat pump with COP 2 at -30 and the associated electric bills have currently no chance here to ever be cheaper than burning gas either nor more friendly for the climate where my government burns coal to produce electricity.
And no, I cannot install enough solar to power this heat pump in the winter or offset the cost of electricity during summer (inverters already turn off in the summer, no electricity is produced as too many neighbors have solar and voltage rises above shutdown threshold in the grid)
The COP coefficient falls down drastically to 1 as soon as temperature drops below -5C and they basically start working as an electric heater. It wouldn’t be a problem if I wasn’t living in a country with the most expensive electricity in Europe which is produced mainly from coal…
You are right, solar panels in which lead is used in manufacturing are definitively easiest and cheapest to recycle.
I can’t wait to see how this solar will power their heat pumps in cold dark cloudy European winter :)
Haha, same here, but you know who gets my money now after their cycles of enshittification?
