Comment Re:So short sighted, and dumb.. (Score 1) 334

You ask: "And how does *also* allowing non fossil-fuel energy, like wind and solar, hurt any of that?"

Answer: intermittency. Adding wind and solar to the generating system just adds cost for no benefit.

If you want detailed case histories of this look at the UK, the usual canary. You will find that the useless intermittent supply from wind and solar comes in, on the bids, far higher than conventional. Regulation is needed to force utilities to buy it. And that is for an intermittent supply. There is no way to deliver dispatchable power from wind and solar at a cost which is competitive with conventional, ie gas or coal.

You doubt it? Go through the UK wind bids and add up the total cost of the UK electricity Net Zero push. Adding wind and solar to a conventional generation system just pushes up costs. Among the costs it adds are constraint payments. There are wind farms in the UK which are making a majority of their income from being paid not to generate, because the wind is supplying when there is no demand.

By the time you factor in the increase in gas consumption consequent on having to rely on open cycle rapid start gas to cover calms and nights its doubtful you even save any emissions either.

Its a great mystery why people who are persuaded of a climate crisis from CO2 emissions have this blind faith in wind and solar generation. Whether or not there is a climate crisis, wind and solar are not a viable generating technology and are not any kind of solution to it.

Paul Homewood has covered the UK wind constracting process in detail if you want that. Most advocates of wind do not. But here he is, as a for example, on constraint payments:

and here he is on the recent AR7 auction

Lots more on costs, subsidies and constraint if you explore the site. The political consensus in the UK seems to be turning against the so called energy transition. The situation in the Gulf is clarifying minds. The absurdity of the idea that moving to intermittent wind and solar is either possible or is going to increase energy security or reduce energy prices is becoming obvious.

Comment Never have really understood these suits (Score 1) 243

Never really understood these suits. They ask for damages, but does this mean they envisage Exxon (just as a for instance) carrying on extracting and selling fossil fuels? Because that is where the money would have to come from to pay the damages if they won.

Or do they want Exxon to close down and stop extracting and selling? At which point the company would be worthless, so it would have little prospect of paying any damages to (for instance) the residents of Colorado (just as a for instance) or anyone else.

And then you have the problems of scale and attribution. Take the problem of scale first. If you look at the percentage of total global emissions that are due to Exxon, they are rather small. Chinese emissions from coal, for instance, will dwarf them. So there is a real problem proving that Exxon has caused significant amounts of the current warming. But it gets worse, the current warming is not itself very large, Globally its around 1C. Very hard to prove that this much warming has caused significant damage, and even harder to prove that anything Exxon has done has caused significant amounts of it.

This would be the first defense. But the second defense would be attribution. Colorado, for instance, is suing because of the damage done to its residents. How do you prove it was Exxon's emissions, as opposed to the Chinese emissions from burning coal? And if the remedy requested is to close down Exxon, how much effect will that have on global emissions, global temps and local weather?

They seem to be suing people for unproven damage which may have been caused (though you'd have to prove this) by a global phenomenon to which Exxon has been a minor contributor. And requesting remedies which will be either ineffective or impossible to obtain.

Its completely different from a case where a company pollutes a bay with mercury, it enters the local food chain and poisons the locals who eat the local fish. And then sue for being poisoned. Or asbestos, where the companies can be sued by people who worked with the stuff and got asbestosis. Or tobacco, where the product has harmed those who used it, and they can sue. Or a state government can sue based on damage to its citizens. The harm done by the habit to the damaged is provable.

Here we have Colorado trying to sue for damage which may or may not have been caused by global emissions, which have only been contributed to minorly by Exxon, and where there is no provable connexion between the damage and the Exxon emissions and where an award of remedy will either be impossible to pay or will have no effect on the problem..

Simply do not understand either how they are goiing to prove what they need, or what remedy they can obtain.

Sue China, maybe. China is mining and burning more coal than the rest of the world put together, and is accounting for more than one third of global emissions. China stops emitting, global emissions really do fall by an amount which will have an effect. Exxon,,,?

"It abandons its core mandate to protect human health and the environment to boost polluting industries and attempts to rewrite the law in order to do so."

This is complete nonsense. There is no threat to American health from American CO2 emissions. No-one has ever shown that.

Reducing US emissions will have no or minimal effect on the level of global emissions. So even if you think the level of global emissions will produce heat which is a danger to health globally (which is again pretty hard or impossible to prove) you still have no case for the Endangerment Finding.

The EPA is not concerned with the global, but with the American, not with global temps, global emissions, the welfare of the rest of the world. If you could show that US emissions were driving warming and that warming was a threat to health, maybe you'd have a point.

But US emissions are not driving global emissions, so you cannot show that. Its at the level of eat your dinner because of the starving children in Africa. How, asks the kid, will that help them? Don't argue with your mother, is the reply.

Comment Re:Seems hostile but has a point (Score 1) 157

I think the idea was the same as the idea of runnng MacOS on generic Intel. People wanted to do that because they liked the OS but did not want to pay over the odds for generic hardware. The Mac people always claimed that the Apple hardware was premium quality, but it never has been, its always just been commodity stuff at an inflated price.

So finally Apple comes up with what seems to be genuinely better hardware - faster, lower power consumption in packages that are at least as good as premium Intel machines. They aren't cheap, but they do seem very nice as hardware.

But, people are now saying, yes to the hardware but no to that awful locked down OS. So they naturally enough try to get Linux working on the hardware.

The difficulty they are running into is the same in both cases. Apple is determined, whenever it gets a market lead in either OS or hardware, to use that to force sell the other. So back in the day we had an OS people really wanted, but which would only run, and later was only permitted to be packaged with, hardware which was either garbage stuff like the Motorola chips or later the PowerPC ones which were too expensive and also real heaters. But the idea was, force them to buy the hardware to get the OS.

Now its force them to use the OS they don't want to be able to use the hardware they want.

The solution is not to deal with these people. Wait a while and the industry will catch up on hardware. Meanwhile just buy the best hardware you can afford and run the OS you want on it. As long as you deal with Apple you will always be in a similar situation, the only thing on their mind is how to lock you in. The specifics will vary, but the song remains the same. Some people are fine with that, some even positively like it, it makes them feel safe and special.

A lot of us don't like it and won't have anything to do with Apple. And then there are the real open source heroes, like the Asahi team, who are ready to throw themselves into a real struggle, Applaud them, support them, and they seem to be winning bit by bit. But its a struggle, its a few guys against one of the largest tech companies in the world. Wish them luck, support them, but its a bit like Wine, its an uphill struggle and probably not ready for production yet, if it ever will be.

Comment An interesting idea (Score 1) 59

I have no desire to add any renewable power generation devices to my home. It was never designed with that in mind, starting with the siting. It will never be optimal. However, I am more than ready to be a consumer of renewable energy, the economics are very compelling. Installing bi-directional batteries, however, will have a negligible impact on my home -- maybe take up some space on my garage wall, that's about it. But having backup power right at hand is a great incentive. And, distributing power storage makes for a far more robust system.

This is a very interesting idea. I'm for it.

As usual no quantification, just the usual hysterical alarmism. Current global emissions are about 37 billion tons a year. How much will these US installations add to that? And how much additional warming will this additional amount lead to?

Can you even say by how much its going to increase US emissions? When doing this, might be an idea to start by saying what these are right now. Then we can see how important it is.

It would help if you could be more specific about who you want destroyed. If you read the detail of the report and look at the tables (which the Guardian fails to give much information about) you will find that most of the emitting is being done by entities which are

(a) outside the West
(b) doing something other than oil extraction and sale.

So are you urging people to get out there and destroy Chinese cement plants and the HQs of the Chinese cement producers? What about the Chinese coal extraction companies, do you want to head up a delegation which goes over there and destroys them? Good luck with that! Or do you want to try persuasion? Join the club, the West has been trying to persuade China and India etc to stop or slow down for the last 20+ years, with absolutely no results.

The key entities are the nation states. That is the only place you will ever get action on curbing emissions. China, for instance, is emitting over one third of global emissions. China is using and extracting more coal than the rest of the world put together. They could stop tomorrow if they wanted to. Which entities are doing this within China is immaterial, they all have such close ties to government that they can be considered extensions of government.

Slashdot should really stop linking to the Guardian. As in this report its disconnected hysterical alarmist rants put together by literature grad. Nothing wrong with being a literature grad. But keep them away from science and engineering topics. All you will get is vague rants, like this one.

Comment Re:But I thought... (Score 1) 38

The question is whether the consequences have any bearing on the rightness or wrongness of the decision. Of decisions in general. The question is, should you consider the consequences at all? Are they relevant?

Whether there is agreement or disagreement as to what the consequences will be is not relevant to this particular question. The question is, are they, whatever they are, relevant?

Bennett tried to isolate this question by focusing on a case where there was no doubt at all about the consequences. His case was one in which most people would have strong feelings about what the certain consequences meant for the decision. Reflected actually in the laws of almost all jurisdictions - even in Ireland after a couple of well known cases revealed the consequences of a total 'whatever the consequences' ban. Then he could ask why those who thought the consequences were irrelevant took that view, what arguments they could have for that position. His conclusion was that the only argument they had was religious authority.

In the climate case there is little dispute about many of the consequences. You can take the IPCC sensitivity estimates for example. Then the argument will be, in cases where the proposed action will have minimal or no effect on climate according to them, should we still do it? Should the UK go to net zero when the effect of its doing so will be to reduce global emissions from 39 billion tons a year to 38.5, and this will have too small an effect to be measurable?

Put it in a simpler way, should the UK take some actions with the justification of reducing global emissions and temperatures if in fact those actions will not do that? And if so, why? Is it relevant that their actions will not have the desired effect? Or is it that emitting is just intrinsically wrong and should be stopped 'whatever the consequences'?

Comment Re:But I thought... (Score 1) 38

Yes, it is a slightly different form of the issue, but it touches the same point. The questions it raises in this form are probably harder ones.

In the Analysis paper (By Johnathan Bennett by the way) the case was of a real condition that does occur (or did occur in the day) where if an abortion was not carried out the mother would certainly die. The Catholic position (as argued by Elizabeth Anscombe) was that abortion was taking innocent life and so was wrong, absolutely. Anscombe argued that to take the consequences into account was arguing for doing evil for the sake of good, and that people who took that view were of 'corrupt mind' and there was no point talking to them.

This is a relatively simple case in that its a choice between two lives, or was in the scenario Bennett was considering. The public policy case seems to be more complicated and harder to see what exactly the issues are. You can imagine Anscome arguing, in the Texas case, that the link between the policy and maternal deaths was not at all clear. In Bennett's case there was an inescapable choice between two lives. Bennett was able to ask, of Anscombe's position, what other than a religions prohibition could justify taking the view that the mother's life should always be the one to go. Anscombe was able to argue that in principle it was wrong to kill one person to save another. The underlying issue was whether the consequences of the action are ethically relevant. Bennett was arguing yes, Anscombe no. It was about whether the goodness or badness of an act is intrinsic to it, or is a property it has in virtue of its consequences.

Part of the sharpness of the difference is caused by the fact, in the example, that there was no way out of the choice. So Bennett took some time to show that much of the theological pleading on these cases depended on refusing to accept this, arguing that the mother's death, in continuation, was not in fact certain, when it was.

In the Texas case this is an easier argument to make. There are, you could argue, many ways in which the maternal deaths can be prevented. Proper public policy can simply make abortion not a necessary choice for anyone by providing alternatives. The argument would be that it is the choice to go for backstreet abortion that is causing the death increase, so the ethical thing is to remedy that. The Texas argument might continue that the consequences of policies are of course relevant. But that its not correct to make public policy on this basis that if we do something ethically correct people will make bad and unnecessary decisions leading to harming themselves.

The difficulty with this argument occurs if you construct limiting cases, because the proponent will almost be forced into a position analogous to that Anscome was faced with: they will end up having to deny human nature as experience shows it to be. it may be that you just cannot provide alternatives which people will choose. At that point the Republicans are forced to the argument, explicit or not, that they wish to ban what they regard as just intrinsically wrong.

The climate and emission case is rather different from either of these. The consequentialist view here is just don't do things which have few or no effects on the supposed problem, but which (hypothetically) have very high costs. You can see it most clearly in the case of the UK, which emits about 450 million tons a year out of a global total of 39 billion. Cut it in half, even eliminate it, and it will make no measurable difference.

Now, do you argue that emitting is intrinsically wrong, and should be stopped whatever the consequences? Or do you try and construct climate consequences of stopping that will justify stopping? Its interesting that the UK has pretty much stopped doing that. They are no longer justifying Net Zero on climate grounds. Or do you decide that it may be best if everyone were to stop, but they are not going to, and so we, US or UK, are living in a world where for us to stop will make no difference, have no benefit, and so cannot be justified. Spend the money on health or literacy.

Its a bit more complicated than China isn't doing it as an excuse for the US not doing something which has a strong justification in itself. The question is what that justification is.
