Dirty downside of 'return to office'; ending WFH could make climate crisis worse

Relatedly, I'd recommend watching the documentary The Year Earth Changed [2] which is about several environmental systems that recovered to some degree during COVID.
I don't think we should necessarily aim to restrict commuting to protect the environment, but now there's evidence that WFH + transitioning to cleaner energy sources can make a significant impact.

One though regarding this. I think complicated and expensive emission controls on cars became grudgingly acceptable because it reduced smog - which people can see.
I wonder if anything would have happened if smog wasn't visible. For example, I wonder if particulates might be worse than smog.
as well as switching from leaded gasoline. within my lifetime we no longer hear about acid rain. it took a lot of convincing to make the switch to unleaded, but the results are obvious. CFCs from spray cans are also an example.
essentially, we've known for decades that emission controls can allow for the climate to repair itself. it just takes a lot of convincing to get people/industry to accept those changes. we didn't need a global pandemic. or did we? GenZ has no experience with the examples i mentioned, so maybe this was their version???
When the COVID lockdowns in India kicked into enforcement, factories shut down, and millions of migrant workers from Eastern UP and Bihar left.
The area in the Doab and Kangra regions was better simply because factories shut down and haven't returned, fueling a localized recession that has resurrected the ghost of Khalistan, exacerbated the Heroin epidemic in the region, and further incentivized the (by Indian standards) highly educated and economically well off local population to emigrate to "Kaneda", "Noo Jeeland", and "Oostralia".
Hopefully with the massive $1.3 billion API/Pharmaceutial precursor industrial park the BJP and Congress Party are building together in that area [0] along with the high speed rail [1] making the commute time to Greater Chandigarh (the largest city and economy north of Delhi) and New Delhi doable within 1 hour and 2.5 hours respectively, we might see an economic recovery.

"Ty Colman, a cofounder and the chief revenue officer at Optera, a carbon-accounting firm that helps organizations quantify their emissions, said that in general, a fully remote company with no offices has the lowest impact-per-employee per year, at less than 1 metric ton of carbon-dioxide equivalent. That includes the uptick in energy used to power computers, keep the lights on, and maintain a comfortable temperature at home."
(versus 1.4 tons for hybrid and 1.7 tons for full time in the office). There's quite a lot more about the effects on the environment in the article.
I doubt there are all that many people meeting the following conditions: work for small companies with one office, live far enough away from that office to need to fly, work for a company with enough extra money sitting around to fly everyone out, work for a company that wants to fly everyone out, are willing to fly out. I really doubt there are enough to have much impact on carbon emissions.
If remote work means people switch their city flats for suburban or rural houses, the impact could reverse
Impact is pretty much more heating/cooling required for house and I'd imagine that would compensate at least part of that.

Do you think people riding public transit pollute more or less than people who don't commute at all?
>Heating/cooling office buildings might be more efficient than everyone doing this to their homes.
Not to mention the fact that houses aren't completely empty when the adults aren't there. Kids, pets, plants, and last but not least, pipes with water in them. All of these will die horribly in cold temperatures.
- What if they are two adults working from the same home vs two different office spaces. - What if you have kids or taking care of elderly at your home. They don't need heat? - What about the quality and amount of food consumed? Would restaurant/sandwich shop near your office have the same preferences for your vegetables? (e.g. not imported from the other side of world, organic, fair-trade?)
Having your home heat up to 90 degrees while you're doing some weekend errands only to crank the AC to cool it back down to 70 to 75 will often times use more electricity than if you just set the AC to 80 while you were gone.
I've seen similar statements a few times, even in this HN thread. Most articles just repeat the statement without showing any numbers. This article does show numbers and the graphs. From the article:
> What we found was that even when the A/C temporarily spikes to recover from the higher indoor temperatures, the overall energy consumption in the setback cases is still less than when maintaining a constant temperature throughout the day.
Full data on https://theconversation.com/does-turning-the-air-conditionin...
One main reason is that when AC is off is that humidity increases which causes cooling harder. This is because the cooling process of an AC unit involves removing humidity from the air as well as heat. When the air is humid, the AC unit has to work harder to remove the excess moisture from the air, which can decrease its overall cooling efficiency.
The other reason is that house and furniture will store heat and then cooling will get harder.
Also AC runs more efficiently if its constant.
I don't think it's always true, which is why I listed the factors that can influence it.
But I am also getting into home automation and just watched a video where some one ran through the numbers on their specific house after getting electricity monitoring connected to their heating and Home Assistant. It's not that clear cut and really depends on your specific home.
1. You run the A/C all day: the gas stays both cold, and dry. Cold, dry air is, it turns out, ok as an insulator. Not very good thermal conductivity at all.
2. You turn the A/C on at the end of the day in a warm, humid environment. The air is moist, which causes two compounding problems: first, the volume of air you need to cool just holds more energy than it would if it was dry. But second, because moist air is more thermally conductive, it's better at coupling heat in from the outside, so more energy is coming into the system as you're trying to cool it.
At least, that's the argument. I haven't run the numbers to check orders of magnitude or anything. I wasn't expecting the difference in thermal properties of dry and moist air to be that significant, but there are some very interesting numbers at https://www.engineeringtoolbox.com/moist-air-properties-d_12....
I only know of two mechanisms that could make holding a temperature more efficient. Heat pumps in winter time should be left to maintain a temperature. If it is well below freezing outside the heat pump may need to fallback to a secondary mechanism of resistive heating. Therefore it's better to not setback the temperature immediately when the home is unoccupied. Variable speed fans on higher end furnaces use less energy at lower RPM, so running a system at full effect requires more power.
Your refrigerator will also work harder as the ambient temperature climbs.
I think that's just power companies not wanting everyone to turn on AC at roughly same time is the reason for those power "saving" tips.
although personally i disregarded that because eight years of living in overpriced CA apartments that were built during the kennedy administration has conditioned (no pun intended) me to feel more comfortable with the AC off.
This seems pretty legit. I also remember getting similar tips from PG&E here in California. Do you have any citations as to why turning off AC/heater is better than leaving them on when we leave home?

> I also remember getting similar tips from PG&E here in California.
Company that sells you energy telling you to not stop consuming energy...
Aside from that, I'd imagine they also want to limit power usage spikes. Everyone coming back from the weekend then running AC on the full blast just consumes a lot of power.
Our office was actually given same advice (just leave AC running over weekend) but it was explicitly said it was to avoid power usage spikes, as cooling back down space that big just takes a lot of power for a long time.
There might be some truth about saving money, if say the rate for power when you'd be turning AC back on is high, vs having that spread over lower rates, but certainly not kWh, at least not if you go out for a whole day or two.
> Do you have any citations as to why turning off AC/heater is better than leaving them on when we leave home?
Basics of thermodynamics ? I think easiest comparison would be boiling water. What makes more sense, to turn off a pot of boiling water after making tea, or to keep it running till you want next cup of tea? You can keep it running to get the next tea instantly ready, or turn it off to not.
It's the same for AC. Turning it off saves power, but it will take longer to get back to the cold state)
You need to keep moving energy (whether heating or cooling) to/from the system to keep it at temperature different than ambient.
The bigger the difference, the more energy needs to be moved.
Keeping AC on constantly is like keeping a pot boiling, you need to pump that energy constantly.
Turning it off means that you stop, and while yes, you have to dump more power to get back to the desired temperature, you save all that power that you'd need to use to keep it at previous temp.
That might be the main reason behind PGE's suggestion - they charge more for 4-9pm usage and it is much cheaper to pre-cool the house between 12-2pm when the demand is lower.
I want to come home in a comfortable house. My parents used to do that. Turn off all heating. Come home, it's cold outside, cold inside and you have to wait until the radiators start to heat up. That takes a while.
But it worked, radiators can heat up a room quite fast.
On the other hand, if we consider heating with a heat-pump, or cooling with a heat-pump (i.e. just a normal AC) they rely on continuously heating up (or cooling down) air (or water in the case of an air-to-water or water-to-water heat-pump).
So you just can NOT quickly change the temperature in a room. So I leave the AC on 78 all day. If I go away for a couple of days I'll set it to 85, but anything higher than that is not recommended.
I would fully support legislation requiring a minimally-programmable thermostat in rental housing.
Most programmable thermostats need batteries, which now have to be changed on a maintenance schedule. One more task for the superintendent.
These batteries often fail without warning. Which means pipes can freeze, leading to property damage. Most homeowners don't even know they have batteries till the heat stops working and they call the HVAC guy.
When property management does not pay the utility bill they will furnish apartments with the cheapest energy hog appliances. When they do pay the utility bill they will lock the thermostat.
If you select an premium apartment and the market is not tilted in favor of landlords as it is in most cities then they tend to care about the customer experience. Since they're making their margin on the higher rent already and they know too much BS will lead to people switching away.
Cold house running during middle of hot day should be lowest efficiency during the day
The energy lost from your home to the environment is dependent on the temperature difference. A warmer house (during the summer) loses less energy than a house that's cooled the entire time. Therefore at least from a pure energy use perspective, it's always cheaper to only turn on the system when you actually need it (ie. when you get home) than trying to maintain the same temperature.
>remember to account for wear and tear on the relevant HVAC equipment.
Without an accurate wear/tear model of HVAC equipment this can easily go either way. You could argue that having the equipment run for longer cycles shortens life because it has to work "harder", but you could also argue the opposite because most of the wear originates from the system starting/stopping and/or thermal stress from it being on/off.
They had kennels but they didn’t have doors or anything.
They would nap in the snow and let it pile up to keep them warm.

Oh those dumb stupid Americans, like Willis Carrier.
Heating/AC might be the only area where energy consumption isn't reduced by WFH.
If we don't decide social norms by what we consider to be pragmatism, how the hell do we decide them at all? I'm not a big believer in climate change, but when people are driving less, the price of gasoline tends to go down even as I need less of it myself. I can get behind that.
The idea that people must work in the office, even when no one can articulate why that's a good idea, is some obscure form of lunacy that is transmitted by being bitten by rabid upper management.
So while the impact of a public transport user is higher than someone staying at home, it's still smaller than that of someone driving to work each day and has greater potential for being shrunk in short order.
If they need fewer because of WFH, they build fewer.
WFH is a net win, if you care about this stuff. And, it turns out, it's a net win even if you don't. Might want to pull your money out of commercial real estate if you have any of that though.
Yeah, at least for busses that's annoying. Like sure, buy the ecological ones but don't just trash a perfectly good bus
- public transport does not run "anyway". If no-one goes on a route, any sane transit system will schedule less frequent services
- heating a big building may be more efficient than a house, but isn't it really dumb to heat it efficiently if you don't have to heat it at all? It's not like people can switch off 100% of their home climate control when they go to the office. Likewise, the building is likely kept in a certain temperature range 24/7.
On the flipside, how many people even have climate-controlled homes year-round? When I used to live in California, air-conditioning was a rare and valuable treasure in a $3k/month apartment. I think I've heard euros claim they don't have air conditioning, too.
This. I don't know about Italy, Spain, and the like, but here in Paris, people mostly don't have A/C in their homes, but basically every office does.
So yeah, carting people to the office and back consumes energy, then you have to consume some more to keep them cool. Bonus points for an impossible number of people burning gas in their cars while waiting around on gridlocked highways and polluting the air. At least public transit uses (mostly) nuclear power here.
In the mild climates of the Bay Area and similar places, sure, but not, at least in the last half century or so, in the LA Basin and the Central Valley.
Go up to the Bay area, and I'd think it was fairly rare.
Basic physics shows that energy = force * distance = mass * acceleration * distance.
So moving more mass, further distances uses more energy than not, especially via the personal cars that are used in the US.
That might be true but doesn’t this assume that people stop heating/cooling their homes whilst they are at work?
Add to that many apartment buildings share utility cost across the unit so there’s even less incentive.
What i see as more likely is people moving o suburbs. Suburbs, especially north american ones, are terrible for the environment and city finances.
More like boomer bosses taking full volume phone calls in cube farms, people eating stinky lunches, zero privacy, and high anxiety as a function of feeling the need to 'look busy'
In London, taking public transport means massively dense crowds. The city is still choked with traffic. Seriosuly, we have to move away from the mindset of uber dense cities to a more sparse living style. Everything in between filled with trees and vegetation.
We built all this tech so that customers can shop remotely, I dont see why workers couln't work from their homes too.
Only the most common use-cases are catered for in a reasonable way. As soon as you take a journey that's an edge-case in any way, get ready for major discomfort. Furniture shopping, major grocery shops, moving house, going from one out-of-the-way place to another, travelling at an odd time.

RTO is pretty much incompatible with having a family.
At the end of the day you lost up to 4h of your time and you paid for it - 1.5h commute - 0.25-0.5h getting presentable - 1h lunch - 1h total in many small bits getting the dishwasher / dryer / washer running
We as workers should form some sort of collective union to push back against these policies.
All employees are replaceable. If we don't fight back now then we will ultimately go back to where we were pre-pandemic.
I've been saying the following for a couple years now:
If you believe governments believe climate change is real(and I phrase it this way to avoid debating people on the reality of AGW), then you accept that incentives will align to reduce energy usage(assuming no mass carbon neutral energy on the horizon, which I believe is a safe assumption) and goad the population away from inefficent suburbs/exburbs and back into higher density urban environments.
And I say this as a lover of suburbia who generally hates urban areas(save Tokyo, which is wonderful).
You don't even have to go down the list very far, the 2nd or maybe 3rd most populous city is any random European country is much more affordable and less crowded than the capital.
And since high earners are all in large cities then so does everyone else move there because that's where the money is.
Instead we should facilitate spreading out, so that wealth can also spread out, and people can enjoy what you just mentioned.
Urban areas may also fix one issue, that of AGW and the looming energy crisis, but you also run into other issues like air pollution increasing in urban areas whilst more people are concentrated inside of them. 80% of urban areas exceed UN air pollution standards. So uh, this change will spike lung cancer deaths and such.
https://www.un.org/sustainabledevelopment/blog/2016/05/un-he...
Urbanisation is already a growing the trend as it is I think in no small part due to the factors you point out.
https://www.un.org/development/desa/en/news/population/2018-...
Examples in California include: car companies killing off successful street cars in SoCal, car dealers and residents block the expansion of BART down the SF Peninsula, residents in northwestern Bay Area blocking BART from entering their area for fear of criminals accessing their area easily from the East Bay.
You're referencing a conspiracy theory/urban legend: https://en.wikipedia.org/wiki/General_Motors_streetcar_consp...
> residents block the expansion of BART down the SF Peninsula, residents in northwestern Bay Area blocking BART from entering their area for fear of criminals accessing their area easily from the East Bay.
This one I believe. I live near a BART station and it is where most crime happens. My next place will be far, far away from any public transportation.
There are a lot of political barriers to that throughout the West.
The result? California is about 3-4 million housing units short of what it needs. And it is getting steadily worse. There is no prospect of this changing any time soon: https://en.wikipedia.org/wiki/California_housing_shortage
When it comes to rent, we're boiling the frog. And the frog is already well-cooked.
> about 3-4 million housing units short of what it needs
Completely separate rant, but I take issue with this. You can go find stats and articles from 2006 saying the same thing, and then, suddenly, we had enough housing. It's almost as if economics drives the housing people choose and when circumstances change they can opt for something else(relocation, MFH, living with family, delaying household formation, etc).

The way we have things arranged now, those with the authority to determine how much carbon does or doesn't get used are not the same people who actually pay carbon taxes.

Kids are the worst.
Even the environment seems to have a negative effect on itself once the ball starts rolling.
ignoring our apparent inability to do anything at all about anything of course
That's also primarily an American issue. They tend to view everything through the lens of 2 political camps and "whose side are you on?".
That kind of view is completely antithetical to actually solving problems.
Yeah, hockey is popular here in Canada, but it's not nearly on the same level as the NFL in the US. And "college sports" etc. is not even a thing. I feel like the American mindset is ever more leaning towards framing everything in a "my team vs your team" dynamic.
But, spreadsheet at hand, it is.
It's always the parents that get offended by this. We are not judging anyone's lifestyle. Relax.
Saying that basically sounds like saying "don't have children peasants, so our the world is better for our overlord's children"
It's always the Americans that get offended by this. Relax. It just happens to be your fault.
Earth _has_ had periods both much warmer than that and with more CO2! There are checks and balances to any system - like Life - that has been around a billion years. So Life will go on. And so I'm skeptical of a claim that "the environment seems to have a negative effect on itself" generally given its longevity. Life will go on -- though...that might be with or without Sapiens.
Migrants from incompatible bring crime and strife. Countries don't want to have more crime and strife.
Hell, my countrymen had reputation for "stealing immigrants" in Germany before the way worse ones arrived there in droves...
Similar cultures can mix. Different ones cause at best strife. AT BEST. Usually worse.
If you live all your life in "every man for himself" and absolute zero regard for law and other human beings then come to country that has those values, well, France happens.
And the appropriate attitude to uncertainty and risk is not to bet everything on the mean outcome.
"could" is typical for wild speculation and at attempts at news-making rather than news-reporting.
Other words in that category "might, potentially, risks"
There is no climate crisis. The climate is changing, we will adapt. It's that simple.
