Renewables Are Now Scotland's Biggest Energy Source

AmiMoJo writes Government figures revealed that Scotland is now generating more power from "clean" technologies than nuclear, coal and gas. The combination of wind, solar and hydroelectric, along with less-publicized sources such as landfill gas and biomass, produced 10.3TWh in the first half of 2014. Over the same period, Scotland generated 7.8TWh from nuclear, 5.6TWh from coal and 1.4TWh from gas, according to figures supplied by National Grid. Renewable sources tend to fluctuate throughout the year, especially in Scotland where the weather is notoriously volatile, but in six-month chunks the country has consistently increased its renewable output.

      NO ONE uses high-enriched uranium for anything except maybe experimental reactors. Do you understand this? 5% enrichment is NOT high-enriched uranium. Do you understand that? Do you also understand that there are nuclear reactors that run on unenriched uranium too? Like CANDU. But those are less efficient than slightly enriched since enrichment process is now very simple (and apparently classified because "no one" can think of the same method twice, given that fundamental technology has been there for decades)

      Or by stroke of other kind of magic, we turn all uranium reactor to thorium or other unproved stuff reactors overnight.

      Almost all reactors can be fed some thorium already. Some designs more than others.

      What everyone utterly fails at is thinking that thorium does not result in the same stuff as uranium. IT DOES!! Thorium biproducts are the same as uranium. Thorium "safety" in a reactor is virtually identical to uranium. If anyone says otherwise, they are talking BULLSHIT. And when they realize that they are talking bullshit, they will be so disappointed that they are likely to jump on the "nuclear can't be safe" bandwagon.

      Only the uninformed nutters would think that if something does not breed heavy plutonium isotopes, then it must be safe. But plutonium has nothing to do with safety of the reactor itself. The point that you "can't make bomb fuel using thorium reactor" is wrong too.

      Uranium == Thorium for the purposes of reactor safety and waste generation.

      As for example of reactor that can burn thorium *right now*, CANDU can do that.

      http://www.nuclearfaq.ca/brat_...

      On-power refuelling and small (half-metre-long) fuel bundles allow almost unlimited capability to shape the axial power distribution, if necessary. Variation of reactivity along a fuel channel can be largely controlled by the fuel shuffling strategy. This allows a variety of enrichments and fissile loadings to be utilized in existing CANDU designs, including slightly-enriched uranium (SEU), mixed oxides (MOX) of plutonium, uranium or thorium, and inert-matrix fuels (containing no fertile material).

      Finally, Nuclear power is 100% CO2 free. Just like hydroelectric, or wind, or solar. And do not bring up bullshit about "material cost in CO2". That cost is moot if CO2-neutral energy source is used to create such materials. Like this,

      http://www.scientificamerican....

      Talking about "material production results in CO2 today so power generation is CO2 intensive" is bullshit to muddle the waters.

The grid (high voltage power lines) was built to connect power stations that were usually less than 30 miles from cities and then smaller grid segments out to the less densely populated areas such as the highlands & islands.

    The challenge Scotland now faces is that a large amount of renewable energy is being produced in the highlands and islands and coastal projects resulting in power having to be shipped "the other way" through the grid. So Scotland has had an enormous new power line from Beauly in the north to Denny in central region to help.

    The biggest hand waving always comes with decommissioning

    Okay, I'll wave my hands about and gobble about 'decommissioning'.

    People tend to increase over time. Energy use increases over time. Globally we are not even close to providing the whole world with a grid coverage and capacity that provides the comfortable existence we ourselves would not tolerate losing. Every renewable dream has us whizzing around in electric vehicles. But this could come true only if the future is nuclear. The renewable numbers just don't work out, even when you imagine a magical solution to the storage problem, and especially when you include ground transportation.

    So where did this 'decommissioning fable' come from? When was it decided --- and by whom --- that ~60 or so years hence there must be a desolate public park at every site chosen for a gigawatt nuclear plant, today?

    Suggest to anyone that a water or sewage treatment plant cannot cost what it costs, it must also gather funds to fund its own destruction and demise and people will shake their heads. But this is crazy! The sewage will always flow downhill to here. We're not going to move a water plant, tear the pipes out of the ground and route them somewhere else. Oh, it's soo much different.

    But is it really? Who is telling us we will be using less energy in the future? Should we listen to them?

    Decommissioning funds gathered for nuclear plants may seem like a great idea, but it has also become an awful idea. It does not make nuclear energy any safer. It has promoted technological sloth, dissuaded investors from supporting (and injecting R&D to improve) the only clean base load energy source on the table. It has handicapped nuclear from being THE cheapest source of energy. It has enabled the most short-sighted and fuck-stupid forms of corporate vandalism. This is because when anyone owns or acquires an aging nuclear plant, they are faced with a choice --- whether to re-invest and re-structure to replace aging components, as they would for any other source, or trigger its destruction and unlock the magic chest of decommission funding. Getting a little kick to the balance sheet by rendering a productive energy source into a blight on the landscape, something intentionally broken that cannot be fixed.

    Such as the Kewaunee Power Station which went offline in 2013 despite that it is in good condition, has maintained a healthy balance sheet, perfect safety record, operating license extended to 2033 and had six months' fuel left in the reactor. All because Dominion is riding the natural gas 'glut' at this brief moment in time. When the glut peaks out Dominion will invest in some other, dirtier short-term solution.

    We should be upgrading these plants and taking them to the next level as we do with every other utility. Given the gigawatt-year track record they have demonstrated It is ludicrous to assume that any nuclear plant operating today deserves to be destroyed rather than upgraded. There are too few of them and they are too precious.

It is a fund owned by customers, held in trust for complete plant dissolution. It cannot be borrowed from or against or used to upgrade the plant, even if this would result in a longer useful life. Typically these funds are held conservatively, though there have been attempts to tax them to higher heaven or play risky games.

      Don't get me wrong, decommissioning funds are a good idea in general for industry, especially for anything involving radioactivity or stored chemicals. But you have to ask yourself for anything, such as my water or sewer plant example, is it likely that we will really want this thing to close and completely disappear in (x) years? If the answer is NO, the return-on-investment burden costs everyone money over it's lifetime because it stifles renovation and innovation. The higher cost and lower profit margin repels good stewards and attracts bad ones (like Dominion). Just as for life insurance, it's not healthy for any one or thing that is truly useful to be considered worth more dead than alive.

If that means that you need to move the office staff off site (seen it ; been employed carrying document boxes and loading desks into lorries ; keeps me out of the pub and the cash is tax-free), then demolish the offices to make room for the new plant, then transfer production (maintaining production to existing contracts - a fucking important point), then tear down the old plant, then build new offices and move office staff back from their (rented) temporary space.

      You're right of course, and drawing any correlation between a nuclear power plant (or any electric plant) and water treatment plants seemed silly at first. They light up whole different areas of the brain. I started asking myself, why is this so?

      Have we become conditioned to think of electricity as something aside from a dire necessity?

      Water and sewer plants are usually sited geographically, and people tend to settle along lakes, rivers and coastlines. Our city is fortunate to be within a gently sloping river valley so treated water is carried to the tap and wastes to the sewer plant mostly by gravity alone. You could be shown a blank topo map of most areas and draw a circle where each plant should be.

      Power plants follow a similar rule of minimizing distance from their primary loads. Our grid was built out as-needed and not for surplus. Therefore aside from a few sad glaring exceptions such as the de-population of Detroit, one will never spot an electric plant somewhere on the landscape and conclude, an electric plant is no longer necessary here. Natural gas plants are being built to supplant coal generation on the grid so there is an emerging phenomenon where a plant here and there is deemed obsolete because "electricity is being generated elsewhere, cheaper, today." In many cases this is being played out by cents on the kWh, where the demise of something locally 'irreplaceable' is triggered by investor sentiment from the glut of natural gas distribution. Some day (perhaps sooner than many think) easily extractable natural gas will peak and begin its inexorable decline, and residents will turn once again to coal. Because of the ridiculous impossibility and expense of completely dismantling coal generation plants, that plant will still be there.

      A properly operating sewer plant removes human toxicity from the environment, making its water discharge safe for human contact and subsequent drinking water treatment plants downstream. Likewise, a properly operating nuclear power plant is the only viable industrial-scale way to remove human toxicity from burning fossil fuel from the environment.

      Despite its vilification and shortage of investment, the nuclear industry has innovated. The Candu and AP1000 light water reactor are the most "walk away safe" designs we can muster from the inherently dangerous combination of fission and water. Molten salt reactors could take this many steps further. Though the radioactivity of the salts is extreme the fissile is bound to the salts and your worst case scenario is a real mess, but it is a manageable mess that would remain there waituing for cleanup, not seep into the environment, as Tepco attempts to chase down Cesium tainted water molecules dispersed to air and sea.

      It is my personal belief that every utility class wind farm will be a silent rusted blight within fifty years, and the electricity customers of those regions will be struggling to overcome the financial hardships imposed by them --- both the subsidized cost of their construction and insufficient generation over their brief lifetime --- but principally the wasting of human resource that diverted them away from better paths that could have been taken.

      Central to all this is the question, do we think there will come a time when we simply do not need this (or that) nuclear power plant anymore? Decommissioning mentality not only forces your hand in that decision, by making nuclear power more expensive than it really is, it encourages a more insidious 'disposable culture' thinking, can't we just close this thi

I'm used to working in projects with decades of planning, years of implementing and hardware that is required to work for decades, then need further decades of deconstruction and site remediation.

      In an attack of small world syndrome I was talking to a friend of 3 decades literally 5 minutes ago about renovating a 1950s War Department Geiger counter, in particular to go hunting for 'hot' particles. Seems an interesting material to have in the house. Though in deference to the wife's sensitivity I might melt down a few kilos of diving lead weights to store them in. (The wife was working 50 odd km down wind from Chernobyl when it went up.)

      If you fancy calling me "reckless", feel free. But I think I've reckoned the hazards quite carefully. I' cautious about radioactivity, but not hysterical. Unless you work in a pretty unusual business, it's likely that I've done more radiation surveys and measurements than you have, and have more friends, colleagues and university class - mates who are registered radiation workers than you. Risk, of various sorts up to and including death under torture, is something I include in pricing up a job. Which is why we (work 'we') declined the proposed job in Somalia 3 years ago : we didn't believe the security plans were adequate. TTBOMK the job has gone back onto the back burner for a decade or so. OTOH I'm pissed that the politicos stopped the North Korea job.

      Sigh, I know what a heat pump does, you seem not so.
      In theory you can generate electricity ... but in practice you wont. A typical steam turbine uses steam in the range of 400 - 500 degrees celsius.
      Generating such a temperature from 15 degrees warm water from the underground is impractible.
      The other simple way to generate electricity from 'warmth' is using thermo electric elements. They work good around and above 200 degrees C. But they are not very efficient, I doubt you get enough electric power back in terms of what you invested to pump heat from 12 - 15 degrees to 200 C.

      So yes, heat pumps are cool ... for heating. Not for generating electric power unless in rare circumstances (like pumping from a 200 degrees reservoir into a 400 degrees one, and generating steam there).

      Yes, you can read a dictionary but don't seem to be able to grasp the concept of what is going on in this situation.
      There's a temperature difference of 50C+ between the solar hot water and the 12C mine water. Making sense yet?
      Heat flows from hot to cold and can be used to do work in the middle. That clear enough yet?

    I was just reinforcing the concept. No argument here.

    It is a good thing the Chinese are building the AP1000 because at this rate the US will not be building a reactor like that any time soon. Plus as we saw with Fukushima nuclear reactors should be made passively safe and the alternative to not having nuclear reactors in a lot of places is increased energy costs and economic misery. There is more than one report than Japan slumped back into their long economic depression in a large part because of the added energy costs of coal imports since the shut down of their nuclear power plants.
