Renewing our obligations
UKWatch.net - 27 Sep 2008
The government is committed to massive new nuclear build in Britain. We do not yet know the details of Gordon Brown’s nuclear plan, least of all how all the new nuclear power stations are to be paid for. But substantial public subsidy is definitely part of the deal, as described by David Lowry on Commentisfree and David Burke, writing in Prospect. After all, EDF would hardly have paid 12.5bn for British Energy if it did not have a clear promise of jam tomorrow. But while the Brown nuclear plan (I am referring here to Gordon Brown, of course, not his brother Andrew, EDF Energy’s head of media relations) glides serenely ahead, where does this leave the UK’s renewable ambitions? Remember that the UK already has a policy to generate 20% of its electricity from renewable sources by 2020, and that this target will need to be doubled to around 40% for the UK to achieve its share of the new EU-wide target to source 20% of all energy from renewables by the same date. So far, Brown has been far more active in trying to water down the UK’s EU renewable target than in finding ways to meet it, in spite of the enormous renewable resources of wind, wave and tide, which sweep our shores. But even if he succeeds in the latest ploy to knock 11% off the UK’s target by not counting the energy used in aviation, the UK still has a lot of renewable generation capacity to build ? approaching 50,000MW of wind for a start. And this creates a problem: nuclear power and intermittent renewables make a very poor match. Ministers and most nuclear advocates now insist that they have nothing against renewables ? on the contrary, they adore them, and all they are advocating is a sensible mix of nuclear power and renewables to give the UK a wonderful new low-carbon electricity system. But the idea does not add up. The wind turbines (onshore and increasingly offshore) that will have to produce most of our renewable electricity can only generate when and where the wind is blowing. The problems of over- and under-supply created by this intermittency can be minimised by spreading wind turbines over a broad geographical area, and by mixing them with other intermittent renewables, such as wave and solar PV. But as the renewable fraction increases, so the need to smooth out the intermittency in the electricity supply rises, and to do this with coal-fired power stations is to defeat our purpose. Nuclear power has a similar but opposite problem. Once a nuclear power station is up and running, the best way to run it is to keep on producing electricity at a constant rate ? until it develops some fault and cuts out altogether, that is. Add the two together, nuclear and intermittent renewables, and what do you get? You might imagine the two complement each other. But the opposite is the case. Because nuclear is “always on”, it does nothing to smooth the supply curve from wind, or to better match total supply to demand, which is also highly variable. Indeed, the renewable supply profile fits consumer demand better than the nuclear straight-line output because the wind blows more during periods of peak electricity demand ? that is mornings and evenings, and winter. By adding nuclear power into the mix, electricity supply actually fits demand worse, not better. So, the more the government backs nuclear power, the more it is undermining the future of renewables in the UK’s energy supply. By backing the nuclear horse so strongly, it is revealing its probable real long-term aim: to use the ineffective and costly Renewables Obligation to fail to meet its targets (which it is guaranteed to do) and then claim that its nuclear power should count as “renewable” because it is low-carbon. Anyway, 2020 is several elections away, and whoever is in charge at the time can deal with the problem then. But maybe I’m wrong and the government really does want renewables to have a major role. If so, here are five important things it ought to be doing to demonstrate its good intentions: 1. The natural companion to intermittent renewables is not nuclear but hydropower, which can be turned on and off to supply electricity when it is needed, and to store energy for when it is in surplus. So, we should seriously expand hydropower capacity in the UK, which currently stands at about 1,500MW, with a view to using it not for baseload generation but to balance gaps between supply and demand. The pumped storage facility at Dinorwig in Wales is already doing this on a huge scale, if for brief periods, with its ability to kick a colossal 1,320MW into the grid at 12 seconds’ notice. We need a large number of plants designed to perform a similar role, but over periods of hours and days, rather than minutes. Small-scale hydro could also have a big role in balancing the output from individual wind farms, perhaps sharing the same grid connections. The new 100MW station at Glendoe (Scotland’s first new large hydro plant in 50 years) is to be welcomed, but there is an even bigger role for small-scale hydro, which could produce a further 650MW. 2. We should also improve our connections to other European countries, as this will help to smooth the overall renewables supply curve, and so benefit all countries. Denmark, Germany, Spain and Portugal are far enough away from the UK for their wind farms to be out of sync with ours, so by linking them all together, wind power surges in one country can compensate for dips in others. There is also growing output from photovoltaic panels (PV) in Germany, Spain and Italy, which can further smooth the renewable supply curve. Also note that Denmark uses its connection to Norway, which gets 99% of its electricity from hydro, to dump surplus wind energy, and draw on the hydro when the wind drops. We should do the same. Concentrated solar power (CSP) from Spain, Portugal and North Africa will also make a huge contribution to renewable generation and supply stability. Like hydro (and unlike solar PV), CSP can store up energy (as heat) and use it to generate electricity when needed. 3. We also need to beef up our own UK grid to link the places our renewable power will be coming from far away from existing power stations ? and using undergound power lines so as not to disfigure our upland landscapes. A new west coast interconnector would be an excellent way to link the many power sources along the UK’s western seaboard, and link to Ireland at the same time. The electricity distribution system also needs to be re-engineered to accommodate small- and medium-scale embedded generation, from local combined heat and power plants to solar PV tiles on domestic roofs. We also need to use price signals on the grid to make our demand responsive to supply, so that, for example, freezers stock up on cold when electricity is cheap, and coast along when the price is high. 4. Scrap the failed Renewables Obligation and replace it with a feed-in tarriffs system, or another system of fixed-price contracts to give renewable developers much needed security for long-term investment. This system would aim to deliver electricity quality ? that is a smooth output matching demand ? not just quantity. To do this, it would pay a premium for diversity of supply to bring in less productive locations, and less economic technologies such as wave power and solar PV. Note that the British Pelamis wave power technology has now been deployed in Portugal thanks to the far greater commitment to renewables of the Portuguese government. 5. Finally, the government should come clean about the deals it has made with EDF and other nuclear generators. It must be seen to hold firm to its promise not to subsidise nuclear power, either overtly or covertly, made in the 2006 Energy Review: “It will be for the private sector to initiate, fund, construct and operate new nuclear plants and to cover the full cost of decommissioning and their full share of long-term waste management costs.”
Lost in Transition
UKWatch.net - 27 Sep 2008
SCHNEWS fails to understand the logic of climate group As global capitalism and its failing markets threaten to fall around our ears, it must be worth imagining what a different way of doing things might look like. And working towards it. That?s what the Transition Towns (TT) supporters want to do. TT’s are a ‘think global act local’ strategy for fighting climate change first put forward by an permaculture academic, Rob Hopkins, in 2005/6 in Kinsale, Ireland. It was first exported to the UK in Totnes, Devon – and converts have been eagerly promoting the idea ever since. And the message seems to be getting through. In the past couple of years the concept (and the leafleting) has been spreading around the country, nay, the world, with over a 100 communities signed up from all over the UK as well as Australia, New Zealand, Chile, the US and most recently, Japan. The movement has also been hitting the headlines here in the UK recently, with just the other week a small town a few miles down the road from SchNEWS towers, Lewes, proudly launching it?s own currency to much media fanfare. With such an emergent new force for social change, you?d think we might have mentioned it in SchNEWS before ? it?s obviously long overdue for us to put the boot in, er we mean, provide an unbiased and dispassionate rational analysis of the whole shebang. So what?s the big idea? Transition Towns (TT) make a good case for the need to change. They recognise the pressing threats of climate change and peak oil (OK, well, the end of super-abundant cheap oil we can agree on, at least – see SchNEWS 644). This means that the globalised, air-mile, oil-driven nonsense needs to stop and more locally based, lower carbon living solutions are needed. The question is, how are we going to get there? But they are not calling for major reform or revolution ? the clue is in the name, folks! – they are looking for an ordered gradual switch over ? a transition. The way they propose this should come about is a somewhat tortuous affair, with the resultant danger that the eco-system or global economic system (or both) may collapse in the meantime. To start the process of your whole town, or city, being designated a ?TT?, all that is needed is a small group of well-meaning committed do-gooders, usually PR friendly middle-class types, to form a Transition Group. This group then works on publicising themselves, arranging film showings, printing leaflets and networking. Once momentum has been sufficiently built, the group can then hold a great ?public unleashing? where the plan goes ?live?. As well as a wave of talks, trades and skills workshops and green-inspired local projects such as tree planting and small permaculture schemes, the main plank of the plan involves gradually formulating a Local Energy Descent Plan? (LEDP), to map out how the local community might one day become more self sufficient, less oil dependant and much greener. If enough local businesses, people and councillors go along with it, or palatable parts of it, the town can officially adopt the mantle of a ?Transition Town? and brand itself accordingly. Measures suggested include the laudable aims of reducing the reliance on multinational corporations for food and goods production, improving energy use and efficiency, increasing recycling, reducing car dependency and a host of other lefty-green objectives. It?s a ?big tent? which allows it to scoop up the efforts of a range of social change groups under one large banner. So what?s the problem? Whilst it?s hard to be too disparaging ? these are all people with the best intentions, attempting to actually take some sort of action as opposed to sitting idly by and waiting for the big collapse – and some change for the good is obviously better than none, there are some flaws in the thinking. Firstly, TT acknowledge that they have no desire to do away with all the trappings of capitalist society ? merely reduce local dependence on it, gradually. They avoid taking on the political roots of all the problems and concentrate on symptoms. A key aim is to get the local council on board. Which many have been surprisingly willing to do…up to a point. Local government itself is charged by central government with working out how to roll out various greenish initiatives, such as to minimise energy needs and increase recycling levels for example, and the LEDP overlaps to some degree with many of their own blueprints for the future ? as long as it?s controlled and the results leave the status quo as little changed as possible, with power flowing upwards, private money still in charge of all those recycling facilities and a capitalistic model still underpinning the local economy. So the council can now use the TT brand wagon to increase uptake of these plans on a wave of public enthusiasm, whilst simultaneously seeming uber green and championing the local over the national. Put this way, its easy to see why many a town hall bigwig are talking up the scheme. Which explains why Lewes council are so behind the latest big venture in the TT vision of the future ? launching local currencies. As people previously used to get hanged for such impertinence as starting yer own money, there must be a catch. And there is. The Lewes Pound (LP) was unveiled last week with a windfall of media coverage. As global financial markets have been taking a beating, perhaps this was a model for the brave new world? Er, not really. Because it isn?t actually a currency at all. It?s actually an ingenious scheme using existing book token legislation. It involves effectively buying a certain amount of sterling (in Lewes? case, 10,000) and then issuing vouchers to the equivalent value, accepted in local shops signing up the scheme. Which many local shops in Lewes were of course only too happy to do ? a welcome free boost to trade as consumers voluntarily pledge to spend their cash with them. Who wouldn?t? The idea is that the LP will increase interest in spending more cash locally, which in theory keeps more of the profit generated circulating locally, as opposed to being syphoned out of the community and into the pockets of global institutions (like Tesco, for example) and their shareholders. Which is great, surely. Well yes, except that the vouchers are redeemable back into cash any time you, or a business-owner wishes – presumably for going shopping at Tesco or making more import deals with third-world tat suppliers. And one of the stated aims of the year long test project is to get national chains accepting them ? which seems a rather strange measure of success and contradicts the whole stated purpose. Money already spent in local shops will continue circulating with little effect on the outside world. While OK for PR and raising public awareness of the explotation by global corporations, it’s not achieving more than affecting a few better-off people?s spending habits. In any event, in Lewes, the big launch has not really gone as planned. Whilst there was massive interest and local flag-waving parochial support for the LP, the well-meaning urging of the TT organisers to keep circulating the vouchers and not change them back into cash has not exactly been heeded. All the LP notes ?sold out? in hours… only to be hoarded and swiftly offered on Ebay for up to 40 for one Lewes Pound as the local populace immediately capitalised on the opportunity to indulge in some rampant currency speculation! They reasoned that as there is a limited supply of individually numbered LP?s, they will in the future be highly collectable – and there have been no shortage of over-the-odds buyers, leaving the whole scheme looking somewhat farcical. The TT group ? having considered but eventually rejected the idea of selling LPs itself for 10 each in order to lesson the black marketeering, have now pledged to print up some more stock – although whether they?ll ever be able to afford to devalue the LP enough to out-bankroll the speculators remains to be seen! As does the overall effect of the Transition Towns movement itself. Whilst we broadly support many of its stated objectives, we cannot see how failing to plan for the much more radical reform of society needs will really work. Attempting to push the existing power structures into implementing some of the required measures will only ever lead to partial change and speaks mainly to people who want things more or less as they are, only slightly greener. ...But we could be wrong!
