I'm very very unconvinced by this, why can't we have a green jobs revolution and sensible environmental protections and growth! These are not exclusive, just caused by a lack of imagination.

They may well be exclusive: https://www.tandfonline.com/doi/abs/10.1080/13563467.2019.15...

Commuting being a hard requirement for modern life in an industrialised country is both a fallacy and perpetuated cargo cult. Most people working in offices today effectively wouldn't have to commute but they still do because employers require them to do so, basically because "that's the way it's always been".

> Most people working in offices today effectively wouldn't have to commute but they still do because employers require them to do so, basically because "that's the way it's always been". It is not just the employers — I’ve worked with many people that think nothing of commuting an hour to work ONE WAY (in their pickup trucks and SUVs no less), even when living closer to work is a perfectly valid option (this is part…

I imagine there's a big difference between a 15 minute commute with a tiny car that doesn't have time to warm up and ends in a crowded parking lot, and an hour in a comfortable roomy Cheverolet Movie-Theater SUV with music playing and heated seats and no family or work or pedestrians and being in the biggest vehicle on the road.

A big SUV is one of the most expensive, most luxurious, nicest things, nicest places to spend time that a lot of people will own - way more overall spent on that seat and its driver-supporting-surroundings than on any Lay-Z-Boy or Aeron chair.

I think "everyone must pay" is even more politically infeasible than setting the tax at 5%, sadly.

> I think "everyone must pay" is even more politically infeasible than setting the tax at 5%, sadly. This surfaces how little say individuals have in our public policy. I specifically added a clause that would more than offset this tax for a modest one bedroom unit for each individual over the age of eighteen. However, I suspect you are right. However, there will be massive lobbying to kill this proposal before it ca…

Outside of the US is my guess for data centers.

They need their electricity and washing machine, but do they need exotic vacations and long commutes in powerful cars? Do they need clothes that are made to be worn for a very short time? Do they need technology that's cheap to the point of it being wasted without an afterthought?

So are you in favor of government telling people where to live and work? I've seriously heard your position many times but no one ever puts forward a solution to making it happen other than the government forcing people to do it. Sounds like a dictatorship to me. and no I don't think employers are all gonna just let people not "come in" to work.

A million times this. My entire office could do their job from home as even when we need something we have to email our team leads and CC our manager so I could be doing that at home, in comfortable clothes, not fighting 50-something…

I friend of mine always asked during job interviews how many bathrooms the office had. The reason for this was that he spent a considerable amount of time in an office, where there was one bathroom for somewhere around two hundred people. Madness.

In the US, that would be illegal:

I think there is only limited correlation between physical energy and money. Money is directly tied with human work: wages for time and effort. Physical energy can vary widely depending on the specific work, even when the price is the same.

The cost of fossil fuel is low because the human work necessary to extract it is very low- it's a problem for the ecology due to no (immediate) human work cost for the Co2 damage. The cost of solar is even lower (which is why it's disruptive)- once you have the solar panel, you don't need any human work.

Do we need a future? If we aren't going to stick to higher density fuels like fossil, nuclear or some sort of interesting synthetic then we are going to struggle to get off the planet earth. There are two very-long-term futures. One where humanity ends up in space, and one where we get the Chicxulub treatment. One of those paths involves us having so much energy that wasting a bit on holidays is irrelevant, and the o…

The way I see it the two paths are: sobriety then fusion then space ortherwise waste then generalized Syria-like conditions then low-budget mad-max reruns.

labor that are still uneducated and do physical work like mining are plenty. so there is not shortage of labor and that keeps wages low. When something is produced on a mass scale, the costs gets lower and that explains why panels are cheap.

The title is misleading in that it's not exactly the conclusion the article arrives at. The article has it quite the other way round: Once energy consumption doesn't grow anymore we either need more efficient means of growth (i.e. less energy consumption per growth unit) or we have to forego growth. It's pre-Industrial-Age Malthus all over again: Barring paradigm shifts that allow for more efficient production planet…

"There have always been paradigm shifts, therefore there will be more", isn't that the very definition of wishful thinking?

Jancovici's proposal isn't to artificially limit growth, it's to do realistic accounting. When you pull out a barrel of oil from the ground, you gain something (in GDP, etc) but you also lose something. If you never account for the losses in biodiversity, resources, clean water, etc then you can pretend you're "growing" while actually having net losses accumulating.
