Renewables to make up half the UK’s power supply

Wind turbines towering over the landscape


When they say ‘flexible power sources’ they mean the ones that are needed when unreliable renewables have largely gone to sleep, for example at night or when it’s not windy. The costs of running such a dual system or the consequences of power shortages, especially in winter, are not mentioned, although they admit that there will be “entire weeks and months” where solar and wind will produce “little energy”. It all sounds unreal.

Renewable energy will account for more than half of the UK’s power supply by 2026, according to a new study, reports Utility Week.

The report by Bloomberg New Energy Finance and commissioned by Eaton and the Renewable Energy Association, claims there will be a “significant acceleration” in the shift to renewable sources over the next 20 years and that this move will create new opportunities for new flexible power sources.

By 2040, almost two thirds (63 per cent) of power will be generated from renewable sources, according to the report and at “certain times” wind and solar energy along could meet total power demand in both the UK and Germany.

But the report also warns that at other times, there will be “entire weeks and months” where solar and wind will produce “little energy”.

It adds high levels of variable generation will create a “very challenging environment” for baseload technologies, such as nuclear and coal and the total back-up capacity needed by 2040 in this country will be much the same as it is today.

According to the study, 70GW will be needed in the UK and 97GW will be needed in Germany in 2040 to meet peak demand during periods of low wind and solar generation.

    This is a plan created by Idiots.
    Even they know it won’t work and yet they insist it be done anyway! A primary electrical power supply that may not contribute for days or months is not a supply! It is an expensive annoyance.
    Insanity runs strong in them…pg

    At around 30% penetration by renewables, conventional electricity generation becomes financially unviable.

    ‘Renewable energy will account for more than half of the UK’s power supply by 2026’

    This is possible quite literally only if the UK is without power occasionally.

    ‘By 2040, almost two thirds (63 per cent) of power will be generated from renewable sources’

    Okay, they are just getting stupid.

    1) ‘By 2040, almost two thirds (63 per cent) of power will be generated from renewable sources’

    2) ‘According to the study, 70 GW will be needed in the UK and 97 GW will be needed in Germany in 2040 to meet peak demand during periods of low wind and solar generation.’

    Put the two together and 70 GW of non-renewable capacity (mostly gas and nuclear) will be doing nothing for about 2/3rds of the time. By their definition that’s enough to power the entire country.

    Even when not needed these places have to be manned and ready to run 24/7/365. Who pays for all that – as if we didn’t know?

    Bollox; told FoE in 2001 that including biomass, it could be 20%, but would lead to halving of the population in the new LIA.

    They must live in another world not this one. At the moment, 15:50 20171115, Gridwatch is showing Coal, Nuclear and CCGT almost maxed out while wind and solar are supplying sweet FA.

    This rush for unreliables is the reason for the push for the so called smart meters (they should be called what they are – remote controlled load shedding devices) to allow the privileged to maintain power.

  6. Roger,

    Does anyone ever still look at past data and comment on how well temperature has behaved for ten thousand years?

    There is nothing in actual data to support this crazy alarmism.

    We need to come together and study the actual data and understand why it is well behaved.

    I believe I understand and can explain, but even skeptics don’t work with each other to understand which of them is right.

    A correct understanding of temperature change is the only way to beat the alarmists.

    Climate obsessives will just say there were no fuel-intensive industrial economies or billions of humans in those days.

    Difficult to know whether these people ( Bloomberg New Energy Finance and commissioned by Eaton and the Renewable Energy Association) are congenital idiots or rent-seekers of the worst possible kind.
    Either way they should not have a public voice.

    B&T: the word ‘Finance’ is probably a clue 😎

    Huh, just like watching “the Apprentice” – but WE have to pay the Salaries and suffer the effects of their actions. Those people making and enacting the decisions, are self-styled full of their own importance, etc. A political party system encourages this and unless we can stop them by NOT paying, etc and getting them held to account for this , I really do feel we are going back into the Dark Ages, – Anarchy and all that to come around again? I never liked History at school but watching stuff recently, I disagree with the Arrogance of those who tell us to “not look Back” – so what’s the Point of History ? We yabble on about all this for the past few years, put up with the Eco loons, etc. WHY? The best Question to ask anyone is simply WHY ?

  11. Saighdear says:

    Ivan, I note that NOW at approx 1am we have :
    Demand 29.63GW
    Frequency 50.017Hz
    Frequency 50.017Hz
    CCGT 12.72GW
    CCGT 12.72GW
    (42.93%)
    Wind 3.76GW
    Wind 3.76GW
    (12.69%)

    Just for the record – I regularly watch this website and it wants to make you C R Y ! – yes congenital idiots around….. once upon a time the Good shepherd would have hit the newborn ower e heid tae pit it oot o it’s misery !

    I think “whistling in the wind” is the usual term for such wishful thinking. By saying that it will happen, they hope to persuade others to make it become a reality, even though it is unachievable. The free money for wind and solar is coming to an end, but the marketing is becoming more desperate.

  13. tom0mason says:

    ‘By 2040, almost two thirds (63 per cent) of power will be generated from renewable sources’

    And by that time the huge maintenance cost of whirly-gig windmills would be kicking-in.
    Current solar farms will have had at least 20 years of weathering, any guesses as to how well they have survived?

  14. Damian says:

    Right now wind is providing 3.49GW (12.50%)
    I pass a number of turbines on my way to work and they are all spinning merrily despite there being no wind whatsoever.
    Last year these turbines were sitting becalmed most mornings, what has changed?
    It isn’t the weather, how much of our wind energy is provided by diesel turbines?
