Why isn't the goal to provide Africa with the opportunities to generate and consume as much energy as I can?
The distribution of resources is grossly unequal.
It doesn’t make me feel bad and doesn’t strike me like it was meant to. My thought was “whoa, fascinating” and then I moved on with my morning.
Maybe the “feel bad” stuff is a you thing that your projecting out onto somebody else’s words?
The American way of life is not sustainable. Even among developed countries the US is an outlier in terms of their use of resources and energy.
So far tech has enabled us to keep up. Why can't it continue?
We have plenty of sun that hits the desert of the country to power 10x our current energey usage. We have plenty of places to put nukes. Lots of land for wind.
But in terms of resources it is simply not possible. If every human being consumed as many resources as an average American then the planet would go up in smoke in 6 months. That's not really an opinion, these are the numbers.
>Air conditioners use about 6% of all the electricity produced in the United States, at an annual cost of about $29 billion to homeowners.
Of course, all things are not equal between the US and Africa, so the comparison isn't worth mentioning.
Just some of them might be interesting, others not, this one certainly count as interesting to me.
If, for example only, this was a significant contributor to global warming and impending doom, does it matter that our first world comforts are to blame? We don't get special exception just because we're used to a certain standard of living.
I desperately hope we don't need to abandon first world comforts. And i really doubt we would need to. However if, for sake of argument, that was the only solution - our answer should be to acknowledge the burden and take action.
This is all for sake of illustration though. Just that your comment seemed to imply because our first world comforts use more energy that it was somehow unfair to question the impact of said comforts.
But if murder is the only solution, you'd have to murder 10 Nigerians to save the same power consumption as an American; you'd do a lot less murder by focussing your attention.
Where such a comparison does become intensely valuable is when the EU says things like "we will do whatever it takes" in relation to energy and food. The implication there is "we will out-bid anyone" and "anyone" happens to be Africa and much of Asia. That's quite a horrendous way of using your currency to export the famine and freezing that you deserve to people who had no say in your bad policy decisions.
(Or if in some corner of the US renewables production is reduced before fossil sources when load lightens, that's even a bigger wrong)
What if this said, "Reminder that the US use more electricity for its domestic-use TV than the entire African continent."
Electricity consumption is an indicator of economic success. FWIW, I own neither AC nor TV.
The negative externalities are interesting though: using air con inside makes your outside that much hotter on a hot day, whereas in winter, nobody worries about waste heat leaking out.
They're not interesting, because they're absolutely negligible. You're moving heat that was outside, back outside. Your house cooled the outside, and you're just undoing this insignificant amount of energy transfer. The only additional heating is from inefficiencies, which aren't so bad these days.
From a pure energy usage perspective, it may make more sense to live in a warm climate that never needs heating versus a cold climate that never needs AC.
> 88% of U.S. households use air conditioning (AC). Two-thirds of U.S. households use central AC or a central heat pump as their main AC equipment.
But where I live we still need AC, fan just allowed me to put it at 80 instead of 75.
I'm generally hot and without it ... can't imagine how I'd make it.
I sometimes think I"m not far from living life like the people in WALL-E, tied to my machines (in their case chair) unable to manage otherwise.
This is the case of most “I can’t imagine” situations, just do it for a bit and your fear will prove mostly unfounded.

Ah, do you have evidence that >65s weren't dying because of heat stress for those thousands of years? That'd be cheering.
Deciding the excess heat often now caused by climate change should be allowed to kill large numbers of the elderly when AC can prevent it is quite a take. I certainly hope everyone holding such a belief does so because they have already eliminated all sources of emissions in their life that are not literally life and death.
I think you and I agree that for e.g. a young healthy person it's bad and wasteful to keep the same temperature control. However, the comment to which I responded doesn't have the disclaimers you've added; it contributes to a "people should be able to tough it out" narrative that we shouldn't perpetuate when in reality, people are dying unnecessarily.
Something like one out of ten people around the world is over 65. In the US, something like one out of four. That's a huge chunk of humanity, not a corner case to handwave.
Not being an overweight and sedentary young person exaggerating the suffering of being in an 80 degree room.
Citation needed.
If only ~2 in a million die of heat or heat contributed causes per year, either people without air conditioning are incredibly rare (they’re not) or there have to be fairly extreme circumstances to risk death.
Do you really need more evidence or are you just being obtuse? Do you actually think healthy or even most unhealthy adults are risking death without AC in any but the most extreme circumstances?

I'm relatively far north in the USA, but even where I am, I found the 85F+ heat waves unbearable for WFH and sleep. I grew up without AC and grew to hate summers as a result. This summer I discovered that I just do not function intellectually above 80F indoors.
It's a bit different if you're outside with a breeze, enjoying nature, hiking, walking, biking, etc. I seem perfectly capable of reading a book or having a stimulating chat in those situations. But even with a fan going, there's a pretty low temperature ceiling for me where I can't work productively. And if it doesn't get below 70F at night, I can't sleep well, which has even more impact on my happiness and productivity.
So I can survive without AC. But I broke and got an AC unit a couple of weeks ago. This heat wave for the past week or so in the northeast convinced me that I was right to do so. I'm just not happy without it.
It's not "nobody needs AC", but the "oh my god I can't live without AC" is mostly fear. If you push yourself into situations where you're uncomfortably hot/code for a while, you'll find your dependance lessened. That's all.
I'm quite happy with my well-air-conditioned apartment, I have no problem with using it, and it's helpful. But I'm also fine with being outside the perfect temperature bubble sometimes.
A trick that can help with that is have "cold rooms" and let the other rooms raise in temperature.
I'm very comfortable above 80° if I haven't been moving around a bunch, but after I come in from outside work I like a cool room for awhile.
Other than the certainty of frozen pipes
1950, 10% of Americans lived in NYC
The share of Americans living in NYC hasn't fallen all that much: 12M in 1950 to 19M in 2021 [1], during which the US population has gone from 151M to 332M. So 8% to 6%.

I'm not sure they got municipal water service until after he was out of the house, probably in the 70s. They used hand-pumped well water, and had an outhouse.
From his stories about his childhood and young adulthood, it seems lots of poor folks and especially the rural poor were still kickin' it like it was the 1920s, well into the second half of the 20th century.
I assure you, in that climate, it's miserable. After a few years though I guess you just get used to it. Take a shower and never get dry. Sleep with every window open and still sweat constantly and be covered in bugs, too. I remember during a hurricane the power went out and stayed out for nearly a week in mid-August. We pretty much spent that time in our neighbor's swimming pool.
Our refrigerator couldn't handle the heat or humidity and more than a few times we'd pour the milk and it would come out solid.
That said, I survived. You'd be surprised what you can get used to and live through, even if it's unpleasant.
Basically screened in doesn't mean bug-proof, unfortunately. You might be thinking of mesh bug nets which are very fine and do provide more protection.
Now its so hot that she can't imagine not having air-conditioning. An elderly woman (you know how they love the heat) that worked in the fields and cannery her entire life thinks its too hot outside.
Europe gets to 35C and people die. In poorer SE Asian countries they have no AC and temperatures regularly hit 35C with far more humidity, but they do just fine.
Hell, you see workers doing construction work in full gear at those temperatures.
Discovering how much better I sleep when the temp is in the 62-66F range has made a big difference. I'd hate to go back to trying to sleep with temps over 68F, certainly. Over 72F and I basically can't sleep. I mean I'm sure I'd acclimate to some degree, but it's not like I was already used to sleeping in colder temps before I tried it, so I'm pretty sure that range is absolutely better for me, regardless of what I'm accustomed to or able to tolerate.
I think it's more a about if you have lived with AC most of your life or not.
While being fat does mean I get more heat, I have witnessed drastic differences in body temperature adaptation that are independant of the weight of the person. Your ability to change your blood vessels dilatation, produce sweat, and work out your mitochondrias probably plays a big role, and I would imagine they are worse when you are overweight, and better if you lived in Africa or Canada.

I'm going to continue running my AC at night when it's hot.
If in less than a century of introducing a tech your body becomes so dependant to it it impairs a critical body function if you don't have it, yes, it's a handicap.
Also food was different. I noticed that some food make my body temperature rise a lot, and that may play a role.
Complaining about not sleeping well in the middle of a hot summer is very different from not being able to sleep at all in the middle of spring without an AC.
Spring nighttime temps are more like 35-55.
The main trouble's the damn humidity. A very-humid 72 still feels gross. And maybe I could sleep like a baby on a night when it gets down to 60, but if that's a spring or summer night I'll wake up nasty and covered in sweat unless I've got some serious dehumidification going (that's what happens when I go camping—might be cold enough to sleep well, but unless it's Winter or late Fall the high humidity still has unpleasant effects). Plus you get mildew and mold problems if you let a modern, very-sealed-up (so, efficient for AC) house get very humid too often, so it's better to just dehumidify with the AC even if the outdoor temp matches what I'd like it to be indoors.
20 years ago people still bought cars without AC, because we had like 10 actually hot days every year.
For the last 3-4 years people have been buying heat pump ACs like crazy every year, because the heat is getting unbearable.
They'd take more to heat because they often leaked, but they were cooler in the summer also.
Now we heat and cool all the rooms, even on those same older houses.
Now, there are some indoor air quality drawbacks associated with mechanical ventilation, but new standards around higher rates of fresh air intake and new technologies like energy recovery ventilators (which now even come in ductless options) are fixing that.
I used a fan. On especially hot days I would have a bowl of water with a wash rag to help cool me down.
Living in the Midwest in a climate controlled house has definitely changed my tolerance for the heat, and I find it difficult to sleep in the heat when I travel back to my hometown.
Meanwhile... few similar statements about air conditioning. Which in my house -- and that of everyone else I know with an EV -- uses many times the amount of energy that charging a car does. Even when I was commuting 100km a day.
Air conditioning is the cause of pretty much all brownouts where I live here in southern Ontario.
Grid resiliency is obviously important on both fronts. And AC is critical. But it's also really expensive from an energy POV.
My uncle (and a friend of mine in his 50s) is constantly posting stuff about how much pollution EVs cause and I’m confused because the guy lives in LA. “Didn’t you live through smog? Don’t you think even a coal power plant with million dollar scrubbers producing your cars fuel is going to be cleaner than your combustion engine?” My line of thinking is, even if EVs DID create more pollution like he seems to think, it’d be better for the entire population of LA or any other city that the power be generated away from the city in a power plant and not from a million tiny poison spewing vehicles in LA!
He just tells me I “need to do the research” and it annoys the crap out of me. For cities with pollution problems it’s so obvious that EVs are a win it hurts.
It's currently a barrage of two FUD and misinformation talking points "they're actually worse for the environment cuz [rare earth metals|lithium mining|they actually run off coal]" and "they're going to destroy the electrical grid."
It's a remarkably effective campaign, and I suspect ultimately the propagation of these points were financed.
I suspect a lot of the incredulity about energy use and EVs at this point comes down to people's inability to grasp that they're spending so much money on gas [cuz ICE vehicles are inefficient], but the equivalent milage on an EV at regular electrical rates charging at home is so much less. It's inconceivable to people how badly they're currently being ripped off. "There has to be a big catch."
There really isn't. Hence I've been told I'm full-of-it when I make the entirely truthful point that AC costs way more than charging an EV for most commutes. People don't want to believe they're being ripped off that badly.
I think this is an easy one. For people who live in hot climates, not having an AC can be a significant health/safety issue. Same with heat in cold climates. Having a ICE car over an EV car poses no immediate health risk, like this potentially does.
EVs adoption adds stress to an already overstressed power grid. The grid needs to be improved if we want EV charging to be available to the masses. It's not FUD, it's just obvious.
My point is that the specific grid related needs of EVs are not the roadblock to their adoption.
My point is that: A far more serious problem for the grid is increasing temperatures and heat waves and the demands that increased AC puts on it.
So in terms of emphasis ... "the grid" as a talking point about EV adoption is mostly thrown up as a smoke screen to discourage their adoption. And it is intellectually dishonest.
I visited Texas this summer and the consistency of the 100+ degree days turned me off from ever considering that part of the country. I find that it's just too hostile to life; heaven forbid you experience a power outage for a week causing your AC to become a useless heap of metal; what then?
Edit: Does this data count heating as well? Whenever I hear "AC" I typically think cooling, thus my main comment is focused on that aspect. Heating here really only needs to be enough to keep pipes from freezing, beyond that, it's very easy to stay warm with enough clothing, blankets, and body movement.

I remember when we moved in to our current house in 2015; we did the first summer without AC, but had it installed for the next year. Felt like a comfort/luxury thing. We had a bit of cash and thought it would be fun to have central air for the first time. Now I honestly don't know what we'd do if it broke.
One century ago no-one had AC, and even today I suspect that billions of people live in hot climates without AC. Sure you may argue that some of them may not have running water or toilets, either, but I think AC has to be on the 'luxury' side of the scale and also something really 'needed' when people fight the local climate instead of adapting to it.
One aspect is that the US (and other countries) follow a mostly Northern European way of life even in tropical or otherwise hot areas.
For instance, having to wear a suit to work in a glass office in Florida makes no sense and happens because of a disconnect between the dominant culture and the local environment, and modern technology makes this disconnect persist because they can, in this case, just install AC and keep the suit (and the glass walls).
... "By 1980 that number had risen to 63%, and in the 40 years since then air conditioning has grown exponentially and is now present in a whopping 95% of homes in the US according to the most recent US Census." https://www.fixr.com/blog/2021/06/22/presence-of-air-conditi...
You might say that this is because we need it more now, but I think it's actually just that we can afford to install it now in every new home and so we do. It's just considered standard equipment.
I think there's still a lot of low hanging fruit to pick to keep structures cool that we just aren't utilizing because of aesthetics/tradition/fashion. Solar reflective paint, retractable sun shades, etc. "Low-Tech" solutions to knock a few degrees off of the structure's internal temp could make a lot of difference.

Come at me, bro...
For instance, what if we used masonry instead of wood frame houses (masonry tends to insulate better; look at infrared pictures of American wood frame houses and European masonry). Also, orienting houses in proper relation to the sun and arranging rooms in a way that facilitates better air flow (embrace the summer draft). Also, evaporative cooling. I am not proposing we eliminate A/C, only find ways and build in a way that allows us to cool houses for cheaper or even for free.
We will have more deadly heat waves as a result.
We desperately need to install even more air conditioning.
