so just to put this in context: we're having a doubling of installed solar capacity around every 3 years. currently we have 3% of total energy supply from solar energy. so it will take maybe another 15 years to get close to 100% renewable energy (if we assume that exponential growth continues). source: ourworldindata (go to website and hover over solar energy to see numbers)
so we'll end up in 2040 with roughly ... let me do the math ... 1.6°C total temperature difference compared to 1970 in 2040?
what i kinda don't get about this whole thing ... is that kinda, in other countries (look at the middle east), they get bombed daily and none of you bats an eye (well, some do, but still, this has been going on for 50 years and i hardly ever hear anyone talking about it). meanwhile you get one terrorist attack and everyone's supposed to lose their minds over this.
edit: the reason why i am posting that is because i knew that the US was pretty fucking big, but this just kinda puts numbers on the game, if you know what i mean.
well yeah subsidies, partially, but a whole lot of area in the US is good for grazing, but not good enough for grains. so cows are a natural way to use that landscape, otherwise it goes completely unused. that's also a reason why there exists animal products in the first place.
Although, all that’s about to change since 1/3 of the planet’s fertilizer production was wiped out.
i wouldn't worry about that too much. these things sound scary but we're damn good at industry in basically any country these days, we'll make new fertilizer somehow.
eh, i'd say, here in central europe, all the ingredients for a proper meal are to be had for probably 4€ (roughly $5) but still, restaurants add like a 300% markup to that or sth
i basically stopped going out to eat like a few years ago. i used to go to restaurants basically daily when it was like 6€ for a full, filling lunch. that was the good stuff.
now it's like 8€ for a tiny sandwich and if you go to a "proper restaurant", you easily pay 16€ just for the main course, then add drinks, etc. it's just not worth it.
meanwhile if i eat at home, it's basically never over 10€/day for all the day's food. just mix potato salad with tuna and call it dinner, that's what i do :)
basically "higher quality" laws always make it very difficult for new players (such as your friend) to enter the market, because you have to have a whole lot of assets to start. which means there's less competition -> providers don't have to optimize on price so much -> they can get away with higher mark-ups.
the same is happening with cars, and housing. in the EU for example they require that every car have a few extra sensors (such as driving assistance, check whether the driver falls asleep, etc.). this makes manufacturing cars more expensive -> cars get more expensive. we all (everyone who buys a car) pay for this. they "improve quality" (mandatorily) at our expense.
quantencomputer konnten immer schon bei raumtemperatur laufen, die frage ist nur, was dann noch der kohärenzgrad ist. also wie viele rechenschritten können hintereinander ausgeführt werden, bevor der zustand im system zerfällt?
edit: sry english translation:
Quantum computers have always been able to run at room temperature, the only question is what the degree of coherence then is. So how many calculation steps can be executed in a row before the system's internal state decays?
i never said that other people find all work unpleasant to do. there are many people who do a whole lot of activities voluntarily. (just look at how many people go to the gym, etc.)
But plenty of people, per OP, don’t “like” anything other than shoving food into their mouths, and sleeping.
the only real solution to climate change is renewable energy, and solar energy in particular. capitalism or no capitalism basically doesn't matter.
