I remember a recent investor report posted on HN about declining health of permian basin, and the economics of extraction will increasingly not make sense in 10 years. Seems like no brainer if shale and by connection LNG is on way out. Might also explain Biden stalling LNG expansions especially with NATO on the hook, maybe it's cynical electioneering to his base, but maybe the future of cheap US LNG is not bright vs…
Vaclav Smil's books about energy give some extra context. I have read his Power Density book (eye opening comparison of solar, wind, nuclear, fossil). IIRC Gas extraction has an extremely high EROI (30x) initially, making it a highly productive extractive resource. But each gas well has a productive lifespan of approx 7 years requiring constant activity to sustain development.
Huge fan of Valclav Smil’s work. Note that the significant amount of water required to frack those wells is in the order of 1 million galls or more. Both sides of that is impacting the Edwards Aquifer[1]. Wastewater from wells is finally being treated, but it doesn’t seem to be a widespread practice, yet. It’s also possible that production declines after each subsequent refracking process.

People should be able to live wherever they want. That doesn't imply others should have to subsidize them doing so. It is really quite simple. If someone remote wants power, they should secure power and pay for it at a market clearing rate, given the cost and risk to deliver it.
This is something else. California has wildfires, and climate change has made them worse. Then the people who built their houses in a silly place prone to wildfires watch them burn down. This is becoming a problem as the frequency which with it happens increases, because it can bankrupt fire insurance companies (who then can't pay claims), or make fire insurance there unaffordable and then people don't buy it, their…
I pretty strongly disagree.
There is some liability on the state and voters for anti burn policy. However, there is more liability on the PG&E for failure to adequately mitigate risk, and failure to asses and frontload charges for probable payment.
If homes are uninsurable, then they shouldn't be. That should only be an issue for an insurer and home owner to work out.
If people want to live somewhere uninsurable, or with more expensive power, I have no issue whatsoever, and won't call them silly. That is their perogitive and values. I view it the same way as if someone wants to base jump, or eat a $500 steak. I fully support them doing whatever makes them happy, as long as they don't expect me to pay for it

#624"supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch." If you really want to make it super easy to switch, design new heat pumps that people can install themselves without having to pay a contractor to install one. Start with window units that look like air conditioners.
Window heat pumps already exist. Ex: https://www.lg.com/us/air-conditioners/lg-lw1216hr-window-ai... or https://www.compactappliance.com/koldfront-12000-btu-heat-co... Mini splits are also fairly easy to install and don’t take up a window.
These units use electric resistance heating, they do not heat using heat pumps. Mini splits require some gas handling equipment like a pressure gauge that most people will not have. I'm talking about something plug-n-play that anyone can install easily without hiring a contractor. There were a few actual heat pump window units in the past but they are no longer sold and they never made many of them to start with (or promoted them much). I think window heat pumps should be ubiquitous. Even if they don't heat/cool the entire house/apartment, they would be a very quick way to reduce some significant use of fossil fuels. For any solution that requires a contractor, the contractor will become a bottleneck to deployment and also raise the cost. If you want a quick global warming benefit enlist the millions of ordinary people to make a difference. Don't wait on the utility companies and government.

I live in the Bay Area California and get electricity from PG&E. I use a minimal amount of electricity and I paid 43 cents/kWh last month. Gas from Costco is $4/gal right now. I have a plugin-hybrid which does 4miles/kwh and 45mpg or in terms of money: 9.3miles/$ on electricity and 11.25gas-miles/$ on gasoline. But maybe you don't actually care about fuel efficiency, then you have an argument that it's cheaper to fue…
That’s astonishingly cheap for petrol, wow. We’re paying at least four times in my country minimum…
Wow, where is it 4x the price? Even in places like Norway, it's only double https://www.globalpetrolprices.com/gasoline_prices/

#626Are these reversible, as air conditioners? I'd expect so, but the article doesn't say.

There's a reason NH is called "The Granite State." Planning to put things underground in at least that part of New England is not likely to go very well. It can be done (plenty of places have septic tanks, for example), but it's not easy.
Unless you live in one of the few big cities in NH, you'll likely already have an Artesian (drilled) well. Swap out the pump for a variable speed pump and you should be good to go for a GSHP -- a much better option for NH vs an Air Source Heat Pump. Otherwise, it'll cost $15-20K for a well to be drilled. You get about 1-ton of heating/cooling per 100' of drilled well.
"Artesian" does not mean "drilled". It means the well emits water without pumping.
You have to be downhill from the watershed for that to work.

Is the correct strategy to wait to regulate gas usage until every country on earth does the same? That doesn't seem like a winning strategy. Someone always has to be last.
It is stupid, with less Gas available on the LNG Market other LNG Producers will increase production or they will use other Energy sources such as coal.
It's banning the installation of NEW LNG appliances in homes in Victoria.
It doesn't impact commercial use of LNG, or the extraction or export of LNG.

> will do nothing for emissions How can that be? Direct consumption emissions are eliminated. Those with solar (a growing percentage) reduce their indirect emissions from grid non-renewable generators. And there is a growing percentage of green generation on the grid.
>> will do nothing for emissions > How can that be? Because a reduction of domestic gas usage will just be diverted to less efficient LNG exports. Given that by far the largest source of Victoria's electricity generation capacity is from dirty brown coal [1] if anything banning domestic gas usage might even make emissions worse since it will force people to use only electricity for cooking and heating. > Direct consu…
The chart you link to shows that Brown Coal, as both a total, and as an overall percentage of the grid, is decreasing, with renewables increasing.
Indeed, if you look at the three Brown Coal generators in Victoria[1], Yallorn is due to shut down in 2028 taking ~30% (1480MW) of that away, followed by Loy Yang A in 2035 which will take another ~40% (2200MW) of that capacity.
So, banning new LNG appliances now, and starting that migration will have a net positive impact.
This is true even if the LNG continues to be burned overseas if it's replacing coal fired generation capacity.

I mean, instead of an argument you responded with some kind of rant about your Airbnb experience. So his point still stands.
The reply made no point, so what exactly stands? Reply just said I don't know what I'm talking about, so I explained where my knowledge came from, which is more than the reply did. And somehow that's a better "point"? kids these days.
