Microgrids May Provide Distributed Energy
jobcello wrote to mention a BBC article discussing a new technique for power distribution that might provide electricity using a series of small "microgrids", in a manner similar to peer-to-peer software. From the article: "'This would save something like 20 to 30% of our emissions with hardly anyone knowing it ... A microgrid is a collection of small generators for a collection of users in close proximity ... It supplies heat through the household, but you already have cables in the ground, so it is easy to construct an electricity network. Then you create some sort of control network.' That network could be made into a smart grid using more sophisticated software and grid computing technologies."
the RIAA will never allow it...
from the post:
I believe if you'll check the documentation, that sophisticated smart-grid controller software is part of the new Office 12 release.

And you can bet on countless participants finding ways to not share at a 1:1 ratio, just like on most P2P networks...

I've been investigating solar and wind power generation for my home. I'm on an acre and a half, with well and septic. I run some web and mail servers. It would be really nice to be able to have a water supply and electricity supply independent of the grid. If this sort of grid system gets implemented, it may be incentive for me and others to go ahead with local power generation systems so that we can share. I've been reading about in-home control systems that can regulate when and how power is used so that you can immediately get a 15-30% power savings. If this is also done with these micro-grids, a cumulative savings of 50% might be possible. That would be a substantial factor in reducing entropy buildup (emmissions, heat, etc.). Cool stuff!!!
Helping with organizational effectiveness is our job.
It would not have to. Just because you lose one generator, does not mean that the grid loses electricity. In fact, the neighboring grids would just provide for it.
I prefer the "u" in honour as it seems to be missing these days.
This seems somewhat far-fetched to me.
From what I remember of physics in highschool, the production and transport of electricity is much more efficient when it is done in high volume with high voltages. In a small grid, you'd lose the benefits of that efficiency. It would also require separate maintenance crews, hardware, etc.
It would also raise concerns about standardization. Will the product I just purchased work on a grid down the street? Would you have to replace your appliances when you moved? The biggest benefit of consolitation is, imo, that you don't have to ask these questions. The systems are large enough to span areas well beyond the majority of general user's environments and thus there are few, if any compatability issues (i.e. Currently, if you leave the country, you might need to change your plug type / voltage, but anywhere in the country it should be the same).
Interruption also raises an issue. I'm inclined to think that a larger factility is easier to keep in operation because it's consolidated and more easily accessed by technicians / engineers / etc.
There are some benefits.
Solar power is made feasible, at least partially, in this case. I've always wondered why we don't all just have solar panels on our houses and batteries in the basements. I suppose that living in Southern California gives me a bit of a bias in terms of estimating the feasibility of such a system, but it certainly seems more reasonable than burning copious amounts of fossil fuels.
There are also other "alternative" power sources listed in the article, although it seems to me that large-scale, consolidated power production is still superior, given that the production facilities are clean.
Having grids separated increases security of those facilities in a disaster as there is no single facility whose compromise would cause a power loss to an entire large grid. With small grids, even if your grid goes down, surrounding grids should still be operational. That does, however, raise concerns about maintenance and repair--who's doing it and when?
Why not nuclear?
Nuclear energy is some of the cleanest and most efficient energy production available. Even with the waste being very toxic, its concentration levels are high. It is arguably easier to control the pollution from nuclear by-products than from a coal power plant. In a well-maintained and operated plant, there is virtually no risk of a meltdown, and I'm sure modern technology can be used to further increase the safety of nuclear power.
Chernobyl is the bloody poster-child of anti-nuclear groups, but that's certainly not par for the course in terms of nuclear power. San Onofre is down here in SoCal, and I dare say we have any mutated sea bass or deathclaw walking around. ;)
My vote is for nuclear, hydroelectic, and other efficient, clean, large-scale power sources, or for solar panels on my roof. It'll be interesting to see how this issue plays out.
I thought the reason we built big power plants was that:
1: By putting all your eggs in one basket and Watching That Basket, reliability was increased.
2: Many small generators would cost more and not be as efficient as one big generator, even allowing for larger transmission line losses.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
The reasons are many and varied and mostly center on physics. If you look at best case scenarios with current off the shelf technology and the efficiencies as you scale up, there's a sweet spot where the size versus distribution versus etc. all reaches an optimum level. Our present system is much closer to that sweet spot than microgrids or the other end of the spectrum, one giant planet-wide power station.
We could use high temperature superconductors, fission reactors and with fusion later when they get it to work, and a lot of clearing of the way by the federal government for deployment which is now held up by people using the environment as a smokescreen when what it comes down to is a lot of NIMBY and more to the point a bountiful opportunity for pitiful and pathetic unimportant people to make themselves feel important.
I live in a state where every highway project takes years longer and millions more because the enviros hold up everything *after* the damage is already done until they've milked out the publicity for themselves and finally it gets done in the end and there was no change and nothing saved in terms of environment and plenty of time and money wasted. All for their inane ego festivals.
Right now those same imbeciles are doing everything they can to keep the power transmission companies from fixing outdated and antiquated transmission lines and equipment which first keeps efficiency low and cost of the power transmission high, second it keeps jacking up the danger of massive local outages every year, third it increases the danger to the workers who maintain the system, fourth it increases the chance of creating a regional chain reaction outage, and fifth it increases the chance of a catastrophic failure on one of the big circuits going through the woods and starting a fire.
They are also trying everything they can do to prevent us from tying into regional grids through the west side of CT into New York and across the sound to Long Island. And lastly doing all they can to stand in the way of a gas tanker and pipeline facility. The sanity of putting liquid natural gas ships more than ten miles offshore is obvious in this new age of mega-terrorism and conversely the insanity of making the tankers put into ports near population centers equally obvious. They just don't care. It's all about them.
The best thing we can do with our end of things as consumers is insulate, make efficient use of what we consumer, and use solar electric, thermal, and hydro *where* economical and efficient on our homes. When superconductive storage systems finally come around, we can store the energy compactly that way onsite and until then, unless we want to deal with the danger of poisonous battery chemicals and five thousand pounds of them per home, we're better off simply having a system where we use the energy we generate first and the main grid's power secondly.
But generators aren't going to cut it. We're going from a few hundred stations to a few million and with less efficiency and more pollution and no inspection. Tack on inspection and you can add the psycho enviro leftists to the far right terrorist under every bed paranoids as one more group pushing us closer to a police state; no way would they let fossil fuel generators increase like that without mandating mandatory inspections on your property at any time for any or no reason with no prior notice and reserve the right to shut you down whenever they felt like it.
I don't see a need to create a massive new intrusion on our rights. Like I said, insulate, make efficient use, be efficient in generation where it is fitting to generate it yourself.
Fittingly a lot of the enviros of today were the Mother Earth News types of twenty-five years ago advocating that we all use wood and coal stoves, forge and smelt our own metals, and operate pig farms to feed methane stills. Their former zeal for old low tech is utterly incompatible with their stated beliefs of today. Much like the pictures of them in mullets, gold chains, and neon orange leisure suits were twenty-five years ago.

The utilities will never allow it.
They may fight it, but allowing it isn't up to them. Ever since Travis Price won his first lawsuit against Con Ed over the windmill in New York that was driving his power meter backwards, the utilities have been on the defensive.
