Re: Solar Power in Hawai'i
You simply are not thinking.
I am thinking very clearly: Successful societies aren't built on the whims of electricity Nazis who make it their job to know when people 'need' power and when they don't.
How hard is it really to do your laundry at some time other than the peak time?
Very.
I have a job.
Don't you?
If you are doing dishes using the dishwasher, why can't that happen while you are at work?
It typically does. But waiting to turn the dishwasher on until right before you leave the house is hardly going to have any impact whatsoever on peak load times.
The few things that can reasonably be done on a population level will have little effect to relieve peak load stress.
But even implementing these sort of things is difficult, because now you're talking about building a system that rests on everyone synchronizing their daily tasks to avoid an overload on the system, and the only way to avoid that kind of devastating failure is to literally sit in everyone's fucking house and stop them from using a forbidden appliance outside its approved timeframe.
Otherwise the whole system is just waiting for Martha to start the dishwasher at the wrong time and plunge her whole state into darkness.
Even some seemingly time bound things like cooking can be scheduled so that the major power consuming portions are off peak.
You do know what causes the peak load, don't you?
If you reschedule the 'major power consuming portions', you've only moved the peak, not eliminated them.
It seems to me that you are taking contrary and silly positions just for the purpose of continuing to defend the indefensible.
There is nothing silly about believing that people in free societies should be able to wash their hair as they please.
Especially when we are talking about something as stupid as getting rid of peaking in the electricity demand cycle.
Why the hell does it even matter? The same amount of energy is used regardless. If we're talking about building a system that generates renewable energy when able and then stores it for later use, as long as there is enough captured and stored, then when it's used really doesn't make much difference.
Now if what you are really suggesting is that you would personally be unwilling to behave in such a fashion, then I'll accept that.
I can't. I have a life. My life works around a schedule similar to those of other people. The times I am home are the times when I need lights on (morning and evening); the times when I can do laundry (weekends); or wash dishes (after supper).
...
Also, I think I replied to half of your pre-edited post and half of your post-edited post. I don't feel like sifting through your edits though, so if I missed something important in between clicking 'reply' and submitting this, let me know.

Love your enemies!

Re: Solar Power in Hawai'i
If we move the peak into the valley then it is no longer a peak.
You mean midnight?
A balanced load requires less generating capacity to satisfy. A 1 kw generator will supply 24 kwh in a day running at it's designed capacity. If you want 18 of those kw during 12 hrs of the day then you need a 1.5 kw generator that is running at reduced efficiency for the other 12 hrs. So it ends up costing more for the same amount of power.
Our options are limited. We can either have a very stable system that runs somewhat inefficiently as load changes throughout the day or even year or we can have a very efficient system allowed to operate at maximum capacity but that runs into the problem of potentially crashing in on millions of consumers if Billy decides on having some toast at just the wrong time.
Though with large scale renewable energy systems, where the consumption of power is separated from its generation by the storage medium, these issues like peak load become less important. You just have to have enough power, period.
... but unlimited consumption is not sustainable.
It's not 'unlimited consumption' and it's not 'washing our hair so much' - it's just washing it at the time of our choosing.

Re: Solar Power in Hawai'i
When I what?
I forgot to finish my thought. And I don't know exactly what I was going to say, but the jist of it is that it is made scarce either by limiting it directly or enacting pricing policies that limit its use.
Scarce is scarce - however the scarcity is created.
The individual. You don't need the TV on when you're cooking dinner. And you can delay the start of your dishwasher for up to 6 hours so that it runs at a more appropriate time than when you also need the hot water for bathing.
It's already up to the individual. And individuals don't behave the way you think would be best for them to behave.
So how are you going to get them to behave the way you think best? Be specific.
I'm talking about supplementation.
In that case, you're talking about something that by definition can do nothing to reduce GHG emissions from electricity production.
My garden? Hardly any. Seeds are cheap and they last forever and I don't use many of them. I water a few times during the peak of summer. The cost is on the order of a handful of dollars per year, plus whatever time I spend out there (that I enjoy).
Right. You enjoy it as a hobby - that's why you do it. Not to get necessary food. Because if you did it for that reason you'd starve to death since the methods used in home gardening simply cannot provide the amount of food necessary to feed large societies. Alternatively, if we did use home gardening to supply our societies with food, we'd be running such an inefficient, wasteful, land-intensive operation that the effects on the environment would be orders of magnitude more severe than the effects our current food-production methods have.
Or to really cut to the chase, what we're talking about is economies of scale. Not only do fewer inputs per unit of output create more affordable goods, but since all inputs are ultimately derived from the environment, they create a smaller environmental footprint than producing the same number of goods without the advantages of economies of scale.
Sure, but it makes a nice supplement. Just like solar could.
Okay... But how will that reduce GHG emissions?
The cost of power to the consumer can be lower when the grid is supplemented by a solar system.
This is only true when the price of generation isn't placed directly on the consumers. Home-sized renewable power being put on to the grid, because it is unreliable and intermittent, requires the cycling on and off of the power companies primary generation devices - which run on FF - and the expenses of monitoring and scrambling to do these things. This cycling is inefficient and actually increases the costs of the electricity.
Regulations that establish buy-back programs simply prohibit power companies from charging those costs to their consumers - they don't make those costs go away.
Edited by Jon, : No reason given.

Re: Solar Power in Hawai'i
When the average usage to the grid is low, the battery gets charged by the grid, and when the average usage to the grid is high, your house uses the power from the battery.
I see what you're talking about.
But what is the point of getting rid of the peak?
Adding a solar panel to the situation allows you to generate and store your own power that you don't have to buy from the grid. You can still buy from the grid all you want, but now you have an additional option of not to.
That in no way makes the power more scarce.
Sure. But what you're talking about is something that is not really going to have any effect on GHG emissions - the topic of this thread.
Simply using batteries to flatten out the peaks and valleys in the consumption rates improves efficiency and reduces emissions.
A small amount, yes; because you are basically increasing the baseload, which allows more generators to run non-stop at max capacity.
But how much is saved? And at what additional environmental costs?
No, the cycling off and on is the inefficiency that we are currently dealing with. We already have problems with peaks and valleys in the usage.
Those peaks and valleys aren't the same thing as the intermittency of renewable energy at all. They are predictable and rather steady - the peak 'ramps up' once and then 'ramps down' once.
When it comes to renewables, you have one minute where there is a bunch of power, then a cloud comes over head and you're 'generators' are knocked out so you have to kick on a few gas turbines; once the cloud moves, you've got to shut the gas turbines back off or you overload the system. Then you're good for a while... until the next cloud. And this goes on and on all day long.
The ramping up and ramping down of the peak power period causes some inefficiency, but it is nothing at all like the inefficiency caused by the constant and unpredictable on and off of renewable generation.

Re: Solar Power in Hawai'i
... but of course you are ignoring energy storage technologies which can smooth out the power generation of wind and solar technology.
But on what scale?
Isn't that what this is all about? LNA made some bogus claims about entire populations running on nothing but solar power and I challenged him to prove it.
If you just want to talk about some renewable energy replacing some FF energy some of the time, I am not going to argue with you about that; but I'm also not going to pretend that that's at all meaningful or helpful in solving the problems of global warming.
If we want to make any kind of real impact on GHG, we need to be really upping the scale of our renewable energy sources. And I'm just not convinced the technology's really there yet.

Re: Solar Power in Hawai'i
So you cannot wash your closes in the wee hours of the morning when most people in your locality are asleep.
No.
Because I am also asleep.
I don't have to be awake while the machine's washing - but I do have to be awake to put the clothes in it, and then move them to the drier/hang them.
And all this has to be completed well before I go to work, since I don't so much care to wear wet underwear.
But really: the fact that you're railing on me because I don't wake up at 2:00 am to do my laundry really shows how pathetic your position is.
But waiting to turn the dishwasher on until right before you leave the house is hardly going to have any impact whatsoever on peak load times.
It's one of a collection of things you can do.
And when everyone else does it, then what?

Love your enemies!

Re: Solar Power in Hawai'i
In fact, LNA hasn't made a single post since his suspension about two weeks ago.
Sure he has.
You've made statements to the effect that using solar power to generate large percentages of power (and not all of our current usage) will cause us to have an economy like Kenya ...
Not really.
... and you persist in talking about 100% replacement even when you are not addressing people talking about running on nothing but solar power.
Again, not really.
If you want to talk about something other than 100% replacement, go for it.
But LNA started this thread to harp about global warming and then started pissing on about the miracle of solar power. I'm just going with the flow.
Let's talk about partial replacement. We can start with you getting some figures showing where it's decreased GHG.

Re: Solar Power in Hawai'i
Shallowing down the peaks allows for FF generators to not run non-stop at max capacity.
But that's what you want them to do. When they run at max capacity, they run the most efficiently (unless by 'max' you mean at the point where they're about to blow).
Look at your car. Idling is the least efficient thing you can do with your engine - it runs and burns gas yet propels you nowhere. Going very slow is only a step above idling and your car is still burning up more fuel just in keeping the engine running than what actually goes toward moving you forward. As you increase speed, though, you increase the ratio of fuel being used to move the car to fuel being used just to keep the pulleys spinning - you get more efficiency.
Those peaks and valleys aren't the same thing as the intermittency of renewable energy at all.
Of course not. They're one of the benefits of supplementing traditional energy with renewable ones.
Peaks and valleys are never 'benefits'.
Actually, there's a shorter peak in the morning and then a larger peak in the evening. And then on top of that the height of those peaks varies by day, by week, by month, and by year.
Yes. They are predictable and steady. The power ramps up and ramps down smoothly. Unlike renewables which generate one second and go dead the next.
That's why storage is such a key component, as I've been harping on.
I agree. But the storage technology isn't there; not at a cost that makes it feasible for the majority of people anyway.
Have you looked into the Tesla PowerWall yet?
Yes. Remember? I pointed out how ridiculously expensive it is and how little power storage you get with it: Message 279.

Re: Solar Power in Hawai'i
Okay, so you do understand the concept I'm trying to get across. Thank you.
That's it?
I've always agreed that running on pure renewables would be the ideal as far as reducing electricity-related GHG emissions.
And I've always agreed that the big hurdle to overcome is the storage.
I personally do not see chemical batteries as being the answer to the storage problem. I'd be interested in Dogmafood going further into depth on his concrete-lifting battery idea.

With Great Power...
If it's true we can effect drastic changes in the climate system, then I suppose a few questions need to be answered:
  • What do we want the climate system to look like? What is optimal for our survival and how do we make that happen?
  • If we have to change the climate as part of improving our lives, what level of change is acceptable in return for what level of improvement?
I don't honestly believe any discussion about what we should/can do about anthropogenic climate change can really begin until these questions are answered.
This thread's probably not the place for that discussion... so I started a new one:
The Optimal Climate & Optimal Human Development
