England Could Produce 13 Times More Renewable Energy, Using Less Than 3% of Land (theguardian.com) 222

England could produce 13 times more renewable energy than it does now, while using less than 3% of its land, analysis has found. The Guardian: Onshore wind and solar projects could provide enough electricity to power all the households in England two and a half times over, the research by Exeter University, commissioned by Friends of the Earth (FoE), suggested. Currently, about 17 terawatt hours of electricity a year comes from homegrown renewables on land. But there is potential for 130TWh to come from solar panels, and 96TWh from onshore wind. These figures are reached by only taking into account the most suitable sites, excluding national parks, areas of outstanding natural beauty, higher grade agricultural land and heritage sites.

Some commentators have argued that solar farms will reduce the UK's ability to grow its own food, but the new analysis suggests there is plenty of land that can be used without impairing agricultural production. More land is now taken up by golf courses than solar farms, and developers can be required to enhance biodiversity through simple measures such as maintaining hedgerows and ponds. Onshore windfarms were in effect banned in 2015 by the then prime minister, David Cameron. Rishi Sunak last year claimed to make moves towards lifting the ban, through small changes to the planning regulations, but campaigners say they were ineffectual and real planning reform is needed. No plans were submitted for new windfarms in England last year, and few new developments are coming forward, despite high gas prices, rising bills and onshore wind being the cheapest form of electricity generation.

    UK plans a fleet of small modular nuclear reactors to meet their energy needs.
    https://www.msn.com/en-us/mone... [msn.com]

    The fine article is an admission of concerns on land use from renewable energy in the UK. This is not a new concern as Dr David MacKay pointed out the problems of wind and solar power meeting the energy needs for UK years ago in his book and website. http://www.withouthotair.com/ [withouthotair.com]

    Dr. MacKay spoke on what UK needed to do for low CO2 energy for much of his life, making it a point to not state any conclusions but rather just point to the options and let the audience decide. In the last interview before his death Dr. MacKay deviated from this tactic and stated UK would need nuclear fission as a part of its energy mix or it will fail to meet future energy needs.

    Much ado has been made over rising costs and construction delays for new nuclear power in UK, but both become irrelevant if there's no better option offered. If Friends of the Earth are to live up to their name then they need to do more than express enthusiasm on how UK could grow their renewable energy supply quickly, they must also face the realities of a cold dunkelflaute which can put the nation into a very dangerous and expensive energy shortage. Dr. MacKay's study may be a few years old by now but it is still based on some fundamental realities that exist. Friends of the Earth must know that UK cannot operate on renewable energy alone if they did their study correctly. Thankfully we see reality being recognized by policy makers in the UK, and elsewhere around the world, with investment in nuclear power. We will still need renewable energy but we can't rely on renewable energy alone. Every nation that got to a point of technological and economic development to allow building nuclear power plants have found it difficult to do without. In the USA we've had decades of nuclear fission providing something like 20% of our electricity and with each closing of a nuclear power plant there's increased use of fossil fuels to replace them. This isn't because people hate clean air and a stable climate but because renewable energy cannot reliably provide energy when and where it is needed.

    To those that believe the solution to the problem of renewable energy being intermittent is energy storage then that shows a lack of understanding the problem. Uranium and thorium is stored energy, stores of energy upon which we can draw from as desired. These are energy stores that will not take up nearly as much valuable land, materials, and other resources as renewable energy and whatever else people have in mind as energy stores. It's great to read on how UK could put up many more affordable onshore windmills, and I'd believe Dr. MacKay would even agree, but that still doesn't eliminate the need for nuclear power in the UK.

      If the fully costed nuclear power stations plan hadn't been scrapped by the Government over a decade ago, they'd be on-stream by now, generating an excess of electricity for even a substantial growth in demand for the next 20 years minimum. Seems there wasn't enough personal enrichment for MPs and their cronies on offer...

        It was a combination of the astronomical cost and the fact that company wants to build them. In the end we had to give massive subsidies to EDF to do it (Hitachi and everyone else declined even with the free money), and get much of the money from Chinese investors. Now they are trying to buy the Chinese out because between them investing and today China became the new Big Bad.

        So all we get is a nuclear plant in 20 odd years, at insane cost, owned by the French government (EDF was nationalized because their

    From the article: "If this capacity was fully developed (although weâ(TM)re not advocating for this due to the abundance of offshore energy potential also available) and if wind was prioritised above solar on sites that are suitable for both, this land would produce 13 times the current onshore wind and solar electricity generation across England. This is equivalent to more than 3 times the electricity currently consumed by homes (20% of total energy consumption). "

    And notice the last bit: this would be 20% of the total energy consumption. A long ways to go.

      You have misunderstood the article.

      What it is saying is that 60% (3 times 20%) of the electricity consumed in the UK could be produced by solar farms and onshore wind.

      Just in case you are skeptical: Annual electricity demand in the UK was 310TWh in 2023 [statista.com] while this proposal is that onshore wind could produce 95TWh and solar 130TWh (from the article).

      What's missing: Offshore wind and rooftop solar.

      • by AmiMoJo ( 196126 )

        Rooftop solar is going to become the next big social divide in the UK. People who have it will enjoy cheap electricity, everyone else will get shafted as the energy companies try to make up for the lost demand and keep their old fossil infrastructure going.

        Same with EV charging. People who can charge at home will enjoy cheap motoring, everyone else gets to pay commercial prices that are as high as for fossil cars.

        The only solution is for the grid itself to become mostly renewable and for individuals to have

          • by AmiMoJo ( 196126 )

            Solar doesn't require direct sunlight to generate electricity. It's overcast today, but solar is still producing 2GW in the UK (estimated due to there being no central way to measure private PV generation).

            Typical payback time is around 5 years, but it varies with climate.

            It's going to get better as climate change takes effect. We are already seeing demand for air conditioning increase.

    • I think you have misunderstood the point of the statistic.

      This is considering just onshore wind and non-rooftop solar which could supply all that our homes need in England. This is significant politically because the current government has effectively banned onshore wind and is very negative to onshore solar largely justified by one of their many culture wars. It's also significant technologically, because the supply could be located closer to the demand which is important because our grid needs a massive a

    3% of the UK landmass is an absolutely massive area.

    This is dumb. Build nuclear reactors. Done.

    • No part of the UK is absolutely massive.

    • I was about to say the same thing, 2.7% of the land is currently covered by buildings which includes cities, industry and their adjacent non-agricultural property (yards, parks, gardens etc).

      You are basically asking humanity to double its footprint so that it you can produce approximately a quarter to half of the energy required to function as a society.

      • TFA is about England, not the UK. 8.7% of England is developed: https://www.gov.uk/government/... [www.gov.uk]

        • Even so that is an absolutely massive increase in land footprint use for a relatively small portion of the energy needed to supply the country.

        Almost 100% of the UK's landmass is already altered through human intervention. There's no "wild" part of the UK to speak of. The human footprint covers the entirety of the UK. We can cope with adding this much extra infrastructure.

      • by Ichijo ( 607641 )

        Let's be consistent here. If agricultural property isn't part of humanity's footprint, then neither are solar and wind farms.

      • Just to put "3% of UK Landmass" into perspective, 1.4% of landmass in England (the most built-up part of the UK) is covered by residential buildings [*].

        So saying 3% we could do this by using just 3% of landmass means covering between twice and three times as much landmass with solar panels and wind turbines as is currently covered by all the houses that exist in the UK, put together.

        That seems quite a lot to me.

      Britain's land mass is actually quite sparsely used overall, with the amount actually developed being around 8%.

      They don't include solar on buildings in their 3% figure, so there is probably a fraction of a percent there. Line roads and railways with them too, as they do in other countries.

      Of course a lot of land can't be used for development, especially up in Scotland. Or at least not for housing and the like, but for wind farms and solar farms, or pumped storage...

      And as they note, they aren't considering

    • Yes, it's a square about 50 miles on a side, or about 115% of the size of Manchester. Build nuclear reactors.

Re-read Dune on hemp paper. Burn the dank and save electricity by turning off your TV. I could go on, but I have to scrub up for the OR.
  • My understanding is that the UK is overcast a lot. Is that right and, if so, does solar really make sense there? How about Wyoming instead? Oops, except they're dedicated to drillin 'n frackin'.
    • No, the UK is a better fit for wind than solar.

      However, as the number of sunny days increases, the viability of solar does too.

    • Solar panels have been designed for cloudy countries. They're a no-brainer for sunny countries but will be viable for covering warehouses, out-of-town supermarkets et al in Britain.

    • Yes it is overcast a lot and for weeks at a time.

      Only during spring and autumn will you find variability with sunny intevals. During recent summers however it can be clear skies for weeks at a time.

      In winter due to the high lattitude even a clear sky generates a fraction of the amount you'd want from solar.

  • The southern most point of the UK, at 49 51 0N is more up North than the entire continental Northern US border (excluding Alaska).

Then comes political issues, corporate control etc. If the entire world wanted to play nice together, we could use that 1.2% in the sahara, power entire world, everyone plays nice, but transportation of that power becomes a big

    • > 1.2% of the sahara could power the entire world

      No. It could genereate the power the world needs but as you will never be able to get the power across the world without loss (unless you use superconductors) then you power Egypt with loads of excess energy.

      Perhaps then EV ships could use such a power system to recharge, while the rebels permit.

  • I checked a wind map and uphill slopes might be possible there but "130TWh to come from solar panels"
    Ummm England doesn't really "do" sunlight. For example: London gets 35 clear days, 180 partly cloudy days, and 150 overcast days annually.
    • So that's 35 days at 100% rated generation, 180 days at 70%+ generation, and 150 days at 30%-70% generation. What number of TWh did you compute from that to make it 'utterly ridiculous'?

      • and 150 days at 30%-70% generation

        I seriously doubt you could get anywhere near that on a typical grey day in England. Id say 35 days a year of actual heat is about right, but the rest of the time its neither warm nor sunny - just grey. I honestly think there are some Scandanavian countries that might actually get more usable sunlight in the days despite the constant snow and ice
