Yes, but at the moment most of the propane is fossil fuel, and the fossil fuel people are best placed to make and distribute the sustainable stuff.

nope, history suggests they are the problem.

Hairyloon, methane and propane can be made by biodegrading, but most of that is used where it is made; often to power farms and such like. I don't think that using 'rubbish' would produce enough for a reliable alternative to power vehicles or much else, even if all rubbish of all sorts was used. Unfortunately we are already using crops to power digestiors in some cases, which isn't a good use of the crop, unless the edible part is removed first.

Producing electricity by sustainable means, which could include digestors, is I think, the best way forward, particularly if home solar or wind can be used to charge cars, and home batteries for other uses. There are losses in any grid; gas or electricity, but they are a good way of circulating the power to where it is needed.

wind turbine, water tidal turbine, pv, gshp, etc use victorian style over-engineering to make em last greener than old cheese using potential compost for energy seems wasteful

It makes sense where the methane would be produced regardless, and where the heat can be useful. The trouble is that those opportunities are fleeting, and eventually the infrastructure existing perverts incentives and suddenly we can't reduce yeah generation because the energy plant needs the feedstock, and we don't manure the field, etc.....

It's hard to compete with the cost of solar, and one day it'll be even harder to compete with fusion.

Agree Slim. Not too sure about fusion; it has proved elusive so far. While I admit that it took quite a while for nuclear fission energy to become available; the first plant in the UK 'went critical' the year I was born I believe, and we didn't get nuclear power here for about another 10 years. Fission requires some rather difficult conditions, which so far haven't been achieved in more than very tiny volumes and certainly not enough for a reactor. I can't remember how long they have been working on it, but certainly more than 40 years.

I have always regarded nuclear as a stopgap until we find ways of producing electricity more cleanly. I first came across solar in the mid 1960s when Bell were working on it. I still have a tiny solar cell that powers a buzzer that they gave my father.

At present, solar and wind look like our best ways of producing electricity in the quantity we need. We may find others that don't produce dangerous waste, and with work on solar cells and batteries, we may find ways of avoiding the damaging mining that is currently their problem.

things that move, tidal flow/gravity flow for water, wind flow, solar, geothermal/heat pumps etc

so far nukes have a very worrying history, legacy cleaning has not been factored in to the profit/mil aspects of them
the odd shell of mustard gas ploughed up in belgium is harmless compared to poking about in high level nuke waste for the next million yrs or so
ps much of it is either too hot to handle or undocumented and probably "somewhere over there"

mil is messy, civil to create mil is even messier, nuke leccy is energy washing mil or hideous expensive per KWH

i would rather use less leccy than agree to more or new nuke leccy

ps by using well designed grid and battery tech , pump storage, tidal reliability etc. very green, safe and affordable energy sources at large or small scale can cover baseline and peak regardless of weather based energy harvest at a given time

pity the fossil/nuke lobby shills have prevailed with public opinion for at least 6 decades
i have met "the public" ........ umm

Agreed, but fusion will be a different animal.
I know the breakthrough has been ten years away for many decades now, and don't put complete faith in it coming through in time to save us from ourselves. But it is nice to know that they've gotten to net positive energy generation, and longer sustained runs. Makes me hopeful that maybe my kids' generation could see the cheap energy needed to reverse some of the climate harms we're creating.
Whether we can fix politics, economic systems, culture, etc. enough to use it equitably is perhaps an even more concerning question.

a bit quick although a decent yield for dumb apes gravity helps

Battery claims
The following link is to the complete list of claims I have been compiling.

https://martindavidwalker.blogspot.com/2024/09/battery-claims.html

The new claims in the last week are as follows.
March 14th 2925, BYD to show off 1000kw fast chargers
That's enough to fill batteries In 5 minutes. It's obviously a great thing for trucks but EVs generally stop to charge where people actually want to take a break, you really don't want 5 minutes till you get charged for not charging!

It's a long time window for plans to fall apart or be changed, but the first grid scale plant has in fact been planned to produce within the next decade: https://en.m.wikipedia.org/wiki/Commonwealth_Fusion_Systems

"planned" and working are not the same

Nice to know things are progressing, but not sure if I will see the long touted fusion in a useable state. I might be proved wrong, but as has been said; if it works, not sure that it will be used equitably.
