I thought I'd take this away from the other thread.

There are a few people in the anti-turbine camp. However, saying 'not that' without proposing an alternative isn't exactly cricket. It is a bit NIMBYism.

So - given that wind turbines are part of a mixed bag of generation techniques and we can't have coal / gas / oil for ever, what do you propose? Other than nuclear, which should IMHO be a part of the answer.

Nuclear, gas, solar, wave.

The gas from abroad will last us ages and is fairly clean and safe

Takeover somewhere sunny, like Libya, fill it with solar panels, and lay a superconducting power cable back to Blighty.

Energy from waste
biomass
solar (PV and thermal)
more efficient building stock (requires no/minimal heating)
ground- and air-source heat pumps
hydro
hydrogen

Nooclear, preferably Thorium cycle, plus thin-film photovoltaics and massive cables from S. Europe & N Africa for piping in the power.

Yeah, Nuclear seems fine. At the end of the day we've already got loads of Nuclear power stations, either in service or being decommissioned, so we may as well go ahead and build new ones next to the old ones now - the workforce are already there, and the technology is only going to get better.

There was a bit on the news this morning about using fracking in the UK to release loads of natural gas from shale deposits.
What they didn't mention is that we would then have this too look forward to.

Beats lighting farts 🙂

Land based wind turbines are hideously inefficient. If we have to have them stick massive ones in the North Sea - or turn them upside down and use sea currents.

Combined heat and power makes a lot of sense here.

Tidal. New installation off Islay promises guaranteed power for 5,000 homes 23 hrs a day and the capacity around the rest of the coast dwarfs this.

Add on off-shore wind, biomass, hydro, solar etc

Energy efficiency to reduce waste has to be number 1 though.

There will be no new nuclear north of the border.

A mix of tech is needed. but the most important thing is a reduction in energy consumption.

Wind is a part of the answer as is wave, tidal, geothermal. chp. burning waste etc etc

No need for expensive unreliable polluting nukes

New build projects should be made to incorporate solar electricity and water heating panels and/or geothermal heat pumps. If fitted at the new build stage the cost would be greatly reduced.

This could apply to both commercial and domestic buildings.

The reality is though that the only viable source of future power for electricity is the latest generation of nuclear power.

The problem is

"tidal power for 5000 homes" - great, but it's not going to power london is it?

"biomass and waste incineration" - great, but there isn't enough biomass or waste to heat/power the cities that produce it. Take Sheffield, one of the newest plants, it manages to heat the hospital and bits of the university, the other 750,000 people still need energy.

We need big power stations or big renewable projects. Because theres not much you can make more efficient about living in a flat and commuting by tube.

If we want renewables we need to stop thinking "tidal power for 5000 homes" and start thinking "Hoover dam over Loch Ness to power Edinburgh and Glasgow".

Either that or build Nukes.

There is no single answer, it's a mix we need, differnet circumstances are best met with differnt solutons.

energy from waste seems a good way of getting rid of rubbish, but all the waste in the country would run 1, maybe 2 power stations

biomass needs huge areas of land to grow the fuel...if the fuel is a waste product frm somhig else then it makes sense to use it as part of a solution

solar, in the uk? Yeah it will add to the mix, but it isn't reliably sunny here for it to be the answer for us

wind, again winds vary...I'm for turbines though and think they are part of a solution

wave and tidal...now this could make a difference. The UK is in one of the best places in th world to harness this, island nation, edge of the atlantic, big tides and big waves. The Severn barage, if it was ever biult, could supply a significant chunk of power to the UK (I've not looked it up but IIRC it could be over 10%)....very costly to biuld though

Nuclear. We are getting it. The 'Need' doesn't seem t be solely for the electricity it produces.

Coal....I think there is still a place for coal fired stations possibly, possibly.

And a change of lifestyles, reduce the transportaton of people, of food, better insulation, less of the 'disposable' behaviour.

Perhaps I should have said sustainable rather than viable.

Alternative energy like tidal, wave, hydro etc is worth utilising but will not be able to provide for UK energy requirements.
Fossil fuels are getting harder to source.

That leaves nuclear as the main long term provider.

Yeah that's one of the challenges in this country, unfortunately. Something like 70% of current building stock will still be present in the UK in 2050.

This means retrofit options are required. In some cases, gutting buildings can be possible for installation of triple glazing, solar heating, insulation etc, but for others it may be a case of changing their boiler to a micro-CHP running on natural gas (or biomass pellets in the future).

Solar stands out as being different as its the only one external to the closed system of planet earth. It doesn't seem ridiculous to think that photovoltaic efficiencies will steadily increase.

I read a few fundamental photovoltaic papers in the chemistry journals now and again and they always sound exciting, but often involve quite sophisticated systems. Seems a long way from the lab to rolling them out at 10p a sq meter.

We need big power stations or big renewable projects.

Not necessarily - wouldn't energy be better provided through small local initiatives, where communities get to be more actively involved in generation and usage? Makes people more aware of where their energy comes from, and so may change attitudes to its use. Also BIG projects require BIG infrastructure, power losses on transmission, and what about all the waste heat from thermal power stations?

biomass
- growing fuel instead of food?

Biomass can include food waste and animal/people 'waste', so no biomass doesn't necessarily mean extra pressure on food and land use.

burning waste
- Nimby's love this.

Waste isn't necessarily 'burned' - anaerobic digestion and pyrolysis don't involve burning and can be contained in a sealed unit. Projects such as these need good public engagement to make sure that locals are educated and know what they're getting, instead of the knee-jerk reactions (such as on this thread).

"tidal power for 5000 homes" - great, but it's not going to power london is it?

The Islay scheme will generate around 10MW. It is generally recognised that schemes in the Pentland Firth could generate 8TW - around 8% of the total UK electricity requirement. That's just one location.

I know what you mean, but do you know how silicon chips are made? Amazing manufacturing process and incredible high tech to make CPUs that we can hand out for free and throw away when we've finished with them.

That's been around for decades. If you think wind turbines are bad for bird life...!

Burn every scrap of food/animal waste in the world and it won't be anything significant AFAIK.

Exactly, this is what we need.

I like the localy generated argument, but but what did the Islay scheme cost? And did 5000 local people pay for it? and would they have rather paid a smaller ammount for a share in a much bigger (economies of scale) project elswhere? In Holland each village gets its own wind-turbine and they love it, in the UK you cant build on in the middle of nowhere without someone crying "won't someone think of the view/aura/children/migrating lesser spotted wendyball bird" let along within sight.

Reducing consumption is a massive part of it. 'Fabric first' is a mantra that really works - 57% of the UK household energy is for space heating. Reduce that and you are on the way.

Yeah, but we're not talking about supply 100% of the world's energy needs from burning 100% of this waste! It's simply another option in delivering electricity and heat to communities that could benefit from it i.e. a rural Scottish lowlands community would be better suited to this (using excess manure) than central London. Energy provision in the future is about finding the best available solution to fit the needs of individual houses, communities and cities. It will have to be different in each case.

Absolutely. The amount we waste is staggering.
Retail is one culprit, showy sales lighting (often left on overnight), AC blowing with doors wide open.
Do we need 100A supplies into our houses?

No I know, but it's about costs too. Collecting manure from every cow farm would be really expensive for not much power and end up using more energy anyway.

This kind of thing is best for local generation imo.

Where do you live Binners? West Manchester? Davyhulme waste water treatment works (the one under Barton Bridge by the Trafford centre) CHP generates almost 10MW per hour. That's one of over 20 across the North West alone.

genuine question :

as oil rigs run out of oil and become useless in their current location, would there be an opportunity to stick a load of wave/wind/nuclear generation on them? there's a lot of energy out at sea, and if a power plant went pop in the middle of the north sea there's less impact than if it happens on land?

No, they're mobile platforms that move off elsewhere.

in the UK you cant build on in the middle of nowhere without someone crying "won't someone think of the view/aura/children/migrating lesser spotted wendyball bird" let along within sight.

Onshore is not as good as offshore so I'm not so keen on planting a giant whirlygig in beautiful places, but I know of a couple of schemes where local villages have "adopted" one of the turbines in a farm for their own generation as part of the proviso for planning permission.

Ultimately we waste too much and there are too many of us for current technology and energy reserves.

Japan is a fine example of how even in a dangerous part of the world when a natural disaster far beyond what was thought probable when several fails safes stop working, some material has to be vented, that the risk has been very small and well managed. The UK is a piece of cake in comparison.

Liquid Fluoride Thorium Reactors

None of the dangers of reacting solid fuels. The fuel is very abundant. The energy density, although lower than Uranium, is very good. The waste product is much less radioactive. I'm not fully convinced but it is very interesting.

The amount of thorium present in surface mining coal waste is enormous and would provide all the power human society needs for thousands of years, without resorting to any special mining for thorium, or the use of any other form or energy recovery.

A summary of how this technology works:
1) You start with a fluoride salt. In this reactor it will be heated so much that it melts.
2) You dissolve thorium fluoride in the liquid salt.
3) Thorium-232 absobs neutrons and turns info Uranium-233.
4) The Uranium-233 fissions and produces heat plus more neutrons.
The fission products are relatively benign and short-lived compared to those of a traditional reactor.
Advantages include:
1) There is no pressure – unlike traditional nuclear reactors which contain high pressue steam. So the reactor cannot explode.
2) The fuel does not need to be shaped into pellets
3) The reactor can add fuel and remove waste at any time
4) There are no weapon-grade materials involved
5) Thorium is abundant and most of it is used up in the reaction

and even after all that has gone wrong there is very little risk.
Could you be specific about what "is tosh"? The Japanese disaster has proved how safe nuclear can be even in the toughest situations. Everything is built to standards and to a point of failure. Occasionally these standards are found not to be high enough and the next generation is safer.

Plenty of other industrial plants provide risks.

The info I've read says it is as under control as an ongoing heating thing can be - i.e. it's still hot but being cooled. The failsafe failure has not been explained by anyone but since there were either triple or quadruple redundant diesel generators and apparently the plant was not damaged by the quake, that leaves the possibility of what - maintenance?

I'm kind of on the fence about nuclear, I can see it has potential to cause big problems but it also has potential to prevent even bigger ones. Accidents will always happen and newer reactor designs are effectively self-limiting and self containing.

The most obvious solution is to have less people.

Every woman should get one 'breeding voucher'. If they use it they lose their ovaries. Population halves every generation.

It would solve world hunger and poverty too. Just allow the trade in vouchers. Women in crappy parts of the world can sell their voucher to rich people in nice parts of the world. The population of crappy places drops to sustainable levels rapidly and wealth flows in making them less crappy.

And we can burn all the oil we like...

More people get killed mining coal or producing oil per kw/h than get killed by nuclear. More radiation is released by coal stations than nuclear too. And... if you're a believer in global warming the long term human impact of fossil fuels is massively worse than nuclear could ever be.

I've heard this mentioned before - can someone point me in the direction of the evidence and effects of this please?

And... if you're a believer in global warming the long term human impact of fossil fuels is massively worse than nuclear could ever be

Only if you consider climate change as not being a catastrophe

The thing with climate change is that to a certain extent it is predictable (if you believe in it) and so we can adapt to the effects of it, plan for change of land use, moving populations, increased intense weather and so on, over years or decades. You cannot adapt to nuclear fallout, which is unpredictable (as in you don't know if or when it will happen).

Secondly, while it may be safer now relative to other traditional power sources, will this be necessarily true in the future, or do we build nuclear plants which in decades time are actually less safe than the alternatives?

Besides, the safety of an industry has a lot to do with safety standards, regulations, corruption and so on - the mention of coal as being less safe than nuclear is to do with the extraction of the fuel, not the inherent safety of the technology. Improvements in working conditions etc could (although probably never will) negate this argument. Many industries are terrifyingly unsafe, but we still support them for one reason or another, because it doesn't represent a personal danger to ourselves (e.g. diamond mining, deep sea fishing etc), whereas those living in the vicinity of a nuclear plant live with that ever-present danger day to day.

I've lived in the general vicinity of a nuclear plant most of my life. It's never crossed my mind.

The fact that I rarely wear a helmet on a mountainbike is undoubtedly more dangerous. It's a wonder I'm not dead*

No radioactivity is released from the stations while they are running - or almost none. However there is all the waste created and all the "accidental" releases of radioactivity which add up to a huge pollution load over the lifetime of the plant.

Tootall - it is utter tosh and the nuclear aoplogists who have any intelligence know it.

I think this was really nice success story.

Tidal power is the most consistently reliable UK renewable I guess, its a shame wind power has taken so much investment away from tidal and wave.

Failing that harness the energy of people what like in the matrix - London would be a good start! runs away....

"No radioactivity is released from the stations while they are running - or almost none"

[url= http://www.scientificamerican.com/article.cfm?id=coal-ash-is-more-radioactive-than-nuclear-waste ]...the waste produced by coal plants is actually more radioactive than that generated by their nuclear counterparts. In fact, the fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy[/url]

I assume they mean a uranium reactor plant that isn't leaking radiation.

More radiation is released by coal stations than nuclear too.

I've heard this mentioned before - can someone point me in the direction of the evidence and effects of this please?

I believe it comes from this article: http://www.sciencemag.org/content/202/4372/1045.short

which shows that, per megawatt produced, coal produces more airborne radiological dose than nuclear generation. However, as with all good research, it has limits and "[i]does not assess the impact of non-radiological pollutants or the total radiological impacts of a coal versus a nuclear economy.[/i]"

Populist write-up of it here in Scientific American: http://www.scientificamerican.com/article.cfm?id=coal-ash-is-more-radioactive-than-nuclear-waste.

For what it's worth (and I don't think I'm going to change any minds here) I am pro-nuclear, mainly because I like electricity and it is the least worst alternative. [b]All[/b] power generation damages human health. People die in coal mines, helicopters crash in the North Sea etc etc. If anything the way these ancient Japanese reactors have coped reassures me about the safety systems built into these things.

In other words the claim

More radiation is released by coal stations than nuclear too.
is tosh as it ignores waste and "accidental" discharges.

Or more correctly, the claim is not supported by that piece of research. The claim may or may not be true but that paper does not set out to examine it.

It's also worth noting that the paper was published over thirty years ago. Both coal and nuclear technologies have moved on substantially in that time - I'd be surprised if coal stations release anything like the amount of fly ash these days.

Also the vast majority of 'discharges' are not accidental - they are allowable low-level releases.

Thanks for the links.

However, as with all good research, it has limits and "does not assess the impact of non-radiological pollutants or the total radiological impacts of a coal versus a nuclear economy."

Correct, and the study also assumes 1% particulate release in 1977. 34 years later I'd hope that particulate removal efficiency was a bit better than that! The study also admits that coal source/type has an influence on concentrations of radioactive material. In most cases too, the increase in dose was not significant.

In the UK, as in the US, fly ash is routinely used in the building trade. SEPA/EA/Defra don't seem to view it as radioactive waste, and I believe they take these things very seriously indeed. And as TJ says, the study counts day-to-day emissions, and not spent fuel rods, cooling water, accidents etc from nuclear.

I'm a fence-sitter with regard to nuclear. I have no problem with existing plants, but I believe there are better solutions for any new builds.

edit: higgo kinda covered some of this in his response while I was typing 🙂
