On June 17th, as new covid cases declined in the UK, Sweden's increased and Sweden posted more new C virus cases than the UK. This is despite the fact that the UK has 6.5 times as many people. This is especialy surprising given that overall, Sweden is on average much less densely populated and thus less naturally prone to easy covid transmission than the UK (and as is widely known, neighbouring Denmark Norway and Finland have had much lower death rates).
But maybe it is less surprising if you factor in the very ageist profile of Swedish political representation and the rampant ageism that is said to happen in Sweden. Despite the fact that the over 65s are a quarter of the Swedish population only 2 per cent of MPs in the Parliament, the Rikstag, are over 65 and old age discrimination is intense.
Indeed whilst in the UK it seems to be the political right that opposes (and. no doubt, weakens) the UK's restrictive policy response, in Sweden, things are such that the nationalist Sweden Democrats are attacking the Social Democrat led Government in Sweden for its 'relaxed' attitude to the coronavirus crisis.
Of course there's many in the UK eager to promote the Swedish solution as a preferred strategy, but alas it often seems to go along with tropes about how the disease is mostly the problem of old men who don't have long to live anyway. Apart from the fact that many young people are worried about getting seriously ill, these ageist stereotypes, which seem to have taken over Swedish politics, are misguided. In fact the people dying of coronavirus likely have many years still to live, as discussed by the recent radio programme 'More or Less'.
But perhaps even worse than this the biggest losers of this trope are older women who are nearly as vulnerable to the old men to the coronavirus. Let's put it this way, if you are a 70-80 year old woman you might be 20-30% less vulnerable than a man of the same age, but you are still hundreds of times more likely to die than someone in their 20s. Old women are becoming invisible in this crisis. And the poorer you are, the worse are your chances.
Sweden has achieved much in terms of gender equality in the Riksdag in that practically half of the MPs are now female - but the success in sidelining the old males has obscured the fact that old women (who are usually poorer and less powerful than older men anyway) have very little representation. Gender equality is a vitally important aim, but it should go hand in hand with reducing ageism, not increasing it. More women MPs should mean an effort to get more older women MPs as well.
There's a big problem here. What it means in practice is that old people are now, in view of the covid crisis, are being ever more oppressed through what should be called severe institutionalist ageism in Sweden. There's some pretty torrid tales that have come out of Sweden of the old being denied oxygen to fight off coronavirus. It would be disastrous politically if this state of affairs led to a far right party taking power in Sweden. But that now looks like becoming a serious possibility, and rampant agesim will be a significant cause of this.

Blue hydrogen - a Trojan horse from oil and gas
The announcement by the German Government that their hydrogen strategy will include support for so-called blue hydrogen as a transitional measure must be regarded as a huge setback for a sustainable energy transition. Essentally what is being proposed is the propping up of oil and gas rather than the alternative – an energy efficient decentralised system based on renewable energy.
The danger is that the British Government will now follow suit.
Blue hydrogen is hydrogen produced from natural gas with the carbon captured and stored – with the caveat of course that the process, for cost reasons, is unlikley to abate more than 85% of the carbon content of the natural gas.
Essentially what the natural gas industry will succeed in doing with ‘blue’ hydrogen is to preserve their multinational gas extraction business by the trick of branding their product differently in different countries. Gas from the same fields will be either branded (further downstream) as ‘blue’ or nothing at all (in other words, normal carbon producting stuff).
Of course it will only be in a few places that the gas will be marketed as ‘blue’. I’m sure lots of fancy consultants will be employed to convince us that really blue gas comes from particular places, but the reality is that in a complex world of international gas trading such distinctions will be window dressing.
Instead of the spending extra investment to kick start the blue hydrogen distribution business we should be spending it on building up energy supplies from renewable energy.
The sort of scheme we should be supporting, indeed being made mandatory is like one being piloted in Wales. This involves local houses being power systems in themselves that generate, store and use the energy efficiently. The Swansea City scheme involves new energy efficient housing being built complete with solar pv panels, batteries and also heat pumps. This will lead to a system that (because of the efficiency of heat pumps) lead to carbon emissions that are 4xs (yes, four times) less than using ‘blue’ hyrdogen. Not only that but the system will also manage fluctuating renewable energy supplies in a way that avoids extra investment in peak power plants and also reduces investment in transmission and distribution wires.
It may be difficult to retrofit some existing houses with heat pumps, although fitting them to district heating systems powered by large scale heat pumps may often be possible. In such cases electric storage heaters can be deployed. These can also be managed so that their electricity use can be timed to fit in with the vailability of renewable energy, again so reducing investment in power plant and distribution wires.
Of course hydrogen has important uses – (although not in space heating where it is inefficient compared to renewable electriciytm, especially with heat pumps). Important uses for green hydrogen include making steel, fertiliser, shipping fuel, cement and storing renewable electricity – but here we should be making investments in green hydrogen – hydrogen supplied from renewable energy via electrolysis – not wasting the money on propping up the oil and gas companies. We face a crucial crossroads here. Do we want to channel lots of money into propping up the existing gas industry or instead use it to build up markets for decentralised sustainable energy?

Nuclear Power switches off wind power in Scotland
A report published today by a newly formed pressure group, 100percentrenewableuk, says that that nuclear power is instrumental in forcing the National Grid to turn off large amounts of wind power in Scotland. Nuclear power is also heavily responsible for the large payments paid by the National Grid to windfarms to turn off (be ‘constrained’) when there is too much electricity on the network. These so-called compensation payments (paid for by electricity consumers in general) have focussed on the Scottish part of the British electricity system. This means that nuclear power is a poor means of balancing wind power.
The newly formed initiative 100percentrenewableuk commissioned a leading energy consultancy, Cornwall Insight, to estimate how much of this practice of turning off wind farms could potentially have been avoided if nuclear power plants were shut down. This allows us to estimate what might happen to windfarm compensation payments if nuclear power plant were able to operate as flexibly as wind farms, that is in being able to turn off production when required by the grid. Two years were selected; 2019 as the most recent completed calendar year, and 2017 the most recent year when both nuclear plants in Scotland (Hunterston B and Torness) were fully operational.
It was found that, in 2017, 94 per cent of the windpower that was turned off could have been generated had nuclear power plant not been operating. In 2019, 77 per cent of windfarm output which was turned off (constrained) could have been generated had the nuclear power plant not been operating. These results indicate a direct relationship between nuclear power and the payments made to windfarms to turn off. Essentially, wind power receives the blame because it would cost a lot more to induce the nuclear power stations to reduce their generation.
Windfarm compensation payments in 2017 were close to £100 million, and around £130 million in 2019. The operation of nuclear power is associated with about £100 million each year paid in compensation to windfarm operators – ie the large bulk of windfarm compensation payments. In 2017, when most nuclear power was being generated, almost all of the constrained wind generation could have been avoided if nuclear power plant had operated flexibly, or shut down.
Dr David Toke, author of the report said: ‘It is wrong for wind power to be ”blamed” by the media for these compensation payments. Inflexible operation of nuclear power plants is switching off wind turbines. Essentially, cheaper electricity production from windfarms is being turned off in order to protect production from nuclear power plant whose production is much more expensive to manage. These nuclear plants either cannot or will not help to balance the grid in these circumstances. This undermines renewable energy and increases the costs to the consumer of operating windfarms’.
This pattern of the failure of nuclear power in the UK to participate effectively in grid balancing has been entrenched in the system of contracts awarded by Government to new nuclear and renewable energy generators, that is Hinkley Point C and offshore windfarms in 2017 and 2019.
These contracts further insulate the inflexible balancing position of new nuclear power. Nuclear power will be guaranteed compensation if they are constrained whilst windfarms will be forced off the grid without being paid for electricity production or compensation for constraints. This will pass the hidden costs of nuclear inflexibility onto wind and solar farms.
In addition, as the proportion of fluctuating renewable energy on the grid increases there will be an increasing number of occasions when wholsesale power prices are negative. But production from Hincley C will always be paid at the premium price even when power prices are negative. On the other hand in future wind and solar generators will lose money irf they generate during periods of negative power prices.
The new group behind the report, 100percentrenewableuk, calls for the idea of providing so-called ‘baseload’ through large centralised generators including nuclear power and fossil fuel power plant to be scrapped in favour of a 100 per cent renewable energy system. Under this system renewable energy should not be constrained but instead stored using various techniques to provide power through both short and long term storage purposes.

EDF in last gasp drive to get blank cheque for Sizewell C
EDF is struggling, but may well still succeed, to persuade the Government to give it what amounts to a blank cheque to build Sizewell C nuclear power plant by wrapping it up in an opaque mechanism called the Regulated Asset Base (RAB). Parallel to this a lot of people in Britain are engaging in a process of self-kiddology. They so deeply believe that nuclear power is necessary for the UK that they will gladly be hoodwinked by a bogus financial scheme that allows another nuclear construction debacle.
Let's cut to the chase. EDF is in big financial trouble - and that's before the current virus crisis. Last December I wrote about the massive financial problems experienced by EDF, http://realfeed-intariffs.blogspot.com/2019/12/the-secret-massive-losses-edf-is.html. If the UK Government commits to the RAB finding of Sizewell C it will be a lifeline to EDF. This will attenuate its problems of trying to get its own French Government to fund its liabilities by getting a different Government, the UK, to offer it what is a virtually unlimited cash facility. EDF is now struggling to afford to build Hinkley C, and so it badly needs the cash fillip of unlimited funds on a a notionally different, but related (and difficult to separate) project.
The trick, as far as EDF is concerned, will be to get the UK Government to agree to fund cost overruns from when it says it starts building Sizewell C. That's the key point of the RAB mechanism. There's a load of tosh being talked about how the biggest problem for nuclear power is the high interest rates on capital it has to pay privately. No, that's not the central issue - the issue is the length of time it takes to build the plant (which makes banks unwilling to lend money of course).
Nuclear developers usually say it takes 5 years for the construction of a nuclear power plant, when in reality it takes at least 8 years, producing a cost overrun of at least 60 per cent. In reality, for the EPR design (being built at Hinkley and Sizewell), given the evidence of EPR reactors being built in France and Finland, construction time is more like 15-20 years - that's maybe 300+ per cent cost overrun before you even count the interest rate payments!
Despite all this evidence a lot of people want to believe in nuclear, however unlikely the financial narrative maybe and however expensive nuclear may be compared to its renewable energy competitors. Cognitive dissonance comes into play and they swallow the EDF story. They refuse to look at all of the other options that allow us to increase low carbon energy shares much more cost-effectively. People also refuse to consider the possibility that actually, you can have a 100 per cent renewable electricity system (or 100 per cent renewable energy system as a whole). We certainly have plenty of cheap offshore wind resources, not to mention onshore wind, solar pv and the possibility of wave and tidal technologies being developed. So why not?
There are very credible means of long term storage of renewable energy ranging from compressed air to ammonia, hydrogen and flow batteries. Biogas from food and farm wastes is another option, already existing, that can be expanded to provide storage. We should be market-testing these options not spending time guaranteeing multi-billions of pounds to EDF for a technology that takes decades to deliver and which will be woefully obsolete by the time it generates anything. Renewable energy can provide energy security for a lot less uncertainty and cost than nuclear power.
But in the UK we proudly prefer to do our own 'traditional' thing (in this case doing nuclear power badly) despite what other countries are doing in a much more modern way, that is until disaster occurs (as with the current C virus crisis). For once we should buck this habit and commit to a 100 per cent renewable energy target (just like Spain has done). We should be far-sighted, and not waste tremendous amounts of taxpayers and consumers money for decades on building nuclear power stations that never seem to be delivered.
