I'm not looking forward to all the power cuts though. There's a notable lack of migrant birds getting through the east coast windfarms too.

They left out... All 30 million British homes could be powered by offshore wind in 2030 one at a time

Meanwhile in other news..... "Physicists build circuit that generates clean, limitless power from graphene
A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current.
"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery.
The findings, published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene—a single layer of carbon atoms—ripples and buckles in a way that holds promise for energy harvesting.
The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado's team found that at room temperature the thermal motion of graphene does in fact induce an alternating current (AC) in a circuit, an achievement thought to be impossible.
In the 1950s, physicist Léon Brillouin published a landmark paper refuting the idea that adding a single diode, a one-way electrical gate, to a circuit is the solution to harvesting energy from Brownian motion. Knowing this, Thibado's group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide separate paths through the circuit, producing a pulsing DC current that performs work on a load resistor."phys.org/news/2020-10-physicists-circuit-limitless-power-graphene.amp

Here we see yet another deleterious effect - in some people - of having contracted COVID-19. It shrinks brain cells.

The 46% rise in electricity prices in UK is a little surprising. It must be all the cheap renewable energy they are adding to the grid.

"German Wind Energy Woes Intensify, “A Farce”… Construction Licenses Plummet 70 Percent In 3 Years
Wind energy investment plummeted in the third quarter of this year in Germany, reports the online IWR here.
“The nine-month figures now available make it clearer that this trend will continue in 2020,” writes the IWR.
Issued construction licenses drop 70 percent in 3 years
Installation of wind energy in Germany peaked in 2017 (see bar chart here), but has since fallen sharply after the German federal government enacted new rules and regulations against their construction.
According to Clean Energy Wire here,
An analysis by energy industry lobby group BDEW found that the falling number of permits issued for onshore wind turbines was the main factor behind the decline, with issued licenses dropping by 70 percent over three years. About 11 GW, roughly 2,000 turbines, were stuck in bureaucratic procedures as of mid-2019.”"More Here> notrickszone.com/2020/10/11/german-wind-energy-woes-intensify-a-farce-construction-licenses-plummet-70-percent-in-3-years/

"What a con! Your overwhelming verdict on the wind power scandal
SINCE Boris Johnson announced his intention to have every home in Britain running on wind-generated power within ten years, TCW has run three articles on the topic.
On Friday we pointed out that the wind does not blow all the time, so there is always a need for back-up generation, unless we are prepared for kettles that won’t boil, washing machines that won’t wash, cookers that won’t cook and electric cars standing useless on our driveways.
On Saturday we discussed the ludicrous situation that environmental activists are pushing for wind turbines regardless of the environmental damage they do. The Royal Society for the Protection of Birds is quite deliberately ignoring evidence that millions of birds are slaughtered every year, a rate which is unsustainable in the short term for many threatened breeds and almost certainly in the long term even for common birds. Some ‘Protection’!"www.conservativewoman.co.uk/your-overwhelming-verdict-on-the-wind-power-scandal/

If you've got hydro, you really don't need anything else, even nuclear (and I say that as a big proponent of nuclear power in general).

Here in Middle Earth, us deplorables have a rate very comparable to Poland ... $0.13 per KWH. Perhaps the Poles have a higher IQ than their EUian comrades. No more Polish jokes.

"First Dutch climate refugees fleeing wind turbines: “The noise is unbearable” Date: 02/11/20Edwin Timmer, De Telegraaf AMSTERDAM – The first Dutch climate refugees are a fact. Not because of wet feet, but because citizens cannot cope with the noise of wind farms.
Residents close to biomass power stations also complain bitterly. Are health and the environment in the Netherlands subordinate to our climate goals? “I do see a similarity with the Groningen gas and the Limburg mines: energy interests outweigh other interests.”"www.thegwpf.com/first-dutch-climate-refugees-fleeing-wind-turbines-the-noise-is-unbearable/

"London, 6 November: The Global Warming Policy Forum (GWPF) is today calling on MPs to start an urgent inquiry into the economic and national security implications of the growing fragility of the UK electricity system.
For two days running, (4th and 5th November), National Grid, UK’s Electricity System Operator has issued System Warnings in the form of an Electricity Margin Notice, alerting the markets to a reduced system margin. In large part this is due to low levels of wind power as a result of a very large high pressure system that covers the whole of the UK, bringing the first frosts of the winter.
At peak load on the 4th of November the UK’s entire transmission connected wind fleet of 18,000 MW in capacity was providing a mere 17% of its possible output (3,000 MW)."wattsupwiththat.com/2020/11/08/gwpf-calls-for-urgent-inquiry-into-rising-blackout-risk-threatening-national-security/And original GWPF article here: "Britain faces an energy emergency as lack of wind exposes tottering electricity system, rescued by coal "www.thegwpf.com/gwpf-calls-for-urgent-inquiry-into-rising-blackout-risk-threatening-national-security/Well what a surprise! The politicians cannot say that they were not warned - but they carried on anyway believing nameplate capacity rather than achieved capacity.
