Solar and wind farms can easily power the UK by 2050, scientists say

A team at the University of Oxford claims that the two technologies could provide ten times our present need

Adam Vaughan, Environment Editor, Tuesday September 26 2023, The Times

Wind and solar power could comfortably supply all the UK’s energy needs by the middle of the century, according to a University of Oxford team.

The researchers calculated that the two renewable technologies could power the nation even after making a conservative estimate that accounted for the amount of land and sea available, energy storage needs, economics and a high future demand for energy.

The analysis found that the UK has enough wind and solar resources to generate 2,896 terawatt hours a year by 2050, or almost ten times today’s electricity needs.

Shotwick Solar Farm in Deeside covers 220 acres and is the biggest in Britain. Similar farms could provide almost of a fifth of our energy

The vast majority, 73 per cent, would come from offshore wind farms, followed by utility-scale solar in fields at 19 per cent. The Solar Energy Industries Association defines a solar project as utility-scale

if it generates greater than 1 megawatt of
solar energy.

Onshore wind farms, which the government this month promised
to unblock in England by changing planning barriers, would supply about 7
per cent. Solar on rooftops would provide less than 1 per cent, because it
was assumed the technology would be largely confined to the south of
Britain and only for south-facing rooftops.

The paper by the Smith School of Enterprise and the Environment said wind and solar had been underestimated in Great Britain, and “predominant narratives that
renewables are too expensive or impractical are wildly out of date”.

Professor Cameron Hepburn, director of the Smith School, said a renewable
powered Britain was now possible because of falling costs of wind and solar
power. He said a recent Royal Society report on energy storage showed the
intermittent nature of renewables could be cost-effectively tackled by
using hydrogen stored in the country’s network of salt caverns. “I
think the public would be stunned that we could power not just the entire
electricity system but the whole energy system of this country with wind
and solar,” Hepburn said.

The country was assumed to need 1,500 terawatts
of energy by 2050, far higher than most other estimates, to ensure the
analysis was conservative. The report assumed 2 per cent of land was given
over to utility-scale solar, 5 per cent of land to onshore wind farms and
10 per cent of the UK’s exclusive economic zone to offshore wind
turbines. Hepburn said wind turbines on land would coexist with farms.

Renewables boost in Germany: turning the corner after a bad year?

DAVID TOKE, SEP 15, 2023  https://davidtoke.substack.com/p/renewables-boost-in-germany-turning

Germany could be turning a corner after a bad year in 2022 as renewables increase and solar power deployment dramatically increases. 2022 saw coal electricity production increase driven by a mixture of the need to substitute for Russian natural gas and the phase-out of nuclear power. In the first half of 2023 compared to the same period in 2022 coal production as a proportion of electricity fell back from 31 per cent to 27 per cent. Renewable energy increased from 48 per cent to 53 per cent. See here.

On top of that solar pv deployment is surging ahead at the rate of over 1 GW a month according to PVMagazine. To put this in context this means that solar pv’s share of electricity production increases by somewhat over 2 per cent per annum. Of course, that’s certainly not enough on its own, but it is a start. Energy Minister Habeck hopes that planning reforms he oversaw will dramatically increase wind power deployment rates. These have been flagging in recent years.

The production of renewable energy is higher in Germany compared to other countries. Rapid progress in renewables growth is set to resume with reforms introduced by the current Government in which the Green Party’s Robert Habeck holds the Economic Affairs and Climate Action portfolio. However Germany is still to recover from the impact of the shutdown of Nordstream 1 gas pipeline from Russia and the big increase in energy costs involved in the pivot away from Russian gas.

Certainly, the embrace of Russia was not a choice favoured by Greens, who argued for energy conservation and renewables instead. But the geopolitical blunder, led by the the SDP’s former Chancellor, Gerhard Schroader, is costing Germany dearly. By contrast there was much greater consensus on phasing out nuclear power after the Fukushima accident in 2011.

The strength of coal interest in Germany has continued, with a completed phase-out now set for 2038. The strength of coal interests in Germany has been much higher compared to the UK because the UK has had (at least in the past) greater availability of cheap gas from the North Sea. Natural gas prices rose for the UK after 2006, but by then most of the coal electricity production had been replaced by natural gas.

There has been a big struggle recently over a heating law. The opposition was fiercely opposed to a mandatory phase-out of gas boilers by 2025. This was ultimately watered down so that, in effect, consumers can still replace gas boilers if there is no provision for local district heating networks.

The provision of district heatimng networks, already a lot more common than in the UK, is to be radically increased. They will be supplied by large-scale heat pumps. It should be mentioned that a law since 2021 effectively bans gas boilers in new buildings – something that is not yet the case in the UK.

Solar energy boost for France

CNR is leading a consortium in the development of “Ombrières
PHotovoltaïquE grand LIneAire”, a solar shading project along the
ViaRhôna cycling route in southern France’s Caderousse department,
alongside the Rhône River.

The pilot project aims to evaluate the
integration of a PV facility into the landscape and assess its energy
performance. The project partners include French cable supplier Nexans,
Schneider Electric, railway operator SNCF, and the SuperGrid Institute.

The PV system will span 900 meters in length and have an installed capacity of
900 kW. It will consist of 30 shaded structures with west-east oriented
solar panels. The consortium will conduct tests on the system’s overall
architecture and the equipment needed for transporting medium voltage
direct current (MVDC) electricity to the delivery point. Construction and
testing are scheduled for the 2025-28 period, following a three-year phase
of engineering studies, research and development (R&D), and prototyping.

In Australia, big batteries and solar push new boundaries on the grid

 The rapid evolution of Australia’s energy system continues apace as the
mild weather of spring and new production benchmarks give voice to the new
capacity that has been added over the past 12 months. As noted earlier this
week, spring is the season for new records because of the good conditions
and moderate demand.

In South Australia on Sunday, solar set a new record
of 120 per cent of local demand in the state (the excess was exported to
Victoria) and on Wednesday and Thursday it was the turn of wind and battery
storage. Wind hit a peak of 141.4 per cent of local demand at 4.35am on
Thursday morning. That wasn’t a record in itself, but the big share of
wind and later solar during the daytime was accompanied by a record amount
of activity from the state’s growing fleet of big batteries.

Ukraine plans up to 1GW wind farm in Chernobyl nuclear disaster zone

Five years after a small solar farm was built at the site, Ukraine has
unveiled plans to develop a potentially huge wind power plant in the
Chernobyl exclusion zone – the site of the worst nuclear power plant
disaster in world history. Der Spiegel reports that a declaration of intent
was signed this week between German-based developer Notus Energy, the
Ukrainian government and electricity transmission system operator
Ukrenergo, to build an up to 1,000MW wind farm, capable of supplying power
to around 800,000 homes – including in the capital Kyiv.

Windfarm bid withdrawn after Ministry of Defence raises nuclear testing station concerns

Midlothian View, by Local Democracy Reporter, Paul Kelly, Wednesday September 13th 2023

A bid for a domestic windfarm in Hawick has been withdrawn after the Ministry of Defence (MoD) raised concerns over its potential impact on a nearby nuclear testing station.

Scottish Borders Council received a planning application for the erection of a 10.4m high turbine on land south east Of Wynburgh Cottage at Langburnshiels.

But the MoD objected to the application due to its potential impact on the Eskdalemuir Seismological Recording Station.

The normally unmanned station was established by the UK Atomic Energy Authority in 1962 as the British contribution to an international network intended to identify and locate underground nuclear tests and, later, monitor compliance with the Comprehensive Nuclear Test Ban Treaty…………………………more https://www.midlothianview.com/news/windfarm-bid-withdrawn-after-mod-raises-nuclear-testing-station-concerns

How a nuclear disaster spurred Fukushima to become a renewables leader

Japan Times, BY FRANCESCO BASSETTI, MINAMISOMA, FUKUSHIMA PREF. – 5 Sept 23

As you reach the coast on Fukushima Prefectural Route 74, which runs between the towns of Minamisoma and Soma, scenes typical of the Japanese countryside — rice paddies and hills blanketed by lush green forests — undergo a swift transformation.

Now, expanses of metal, glass and silicon shimmer in the midday sun, stretching out to a horizon dotted with four white wind turbines, blades humming as they turn in the summer breeze.

Following the 2011 triple disaster — and the subsequent cratering of support for nuclear energy — Fukushima Prefecture has positioned itself at the forefront of Japan’s low-carbon transition.

Few projects better exemplify that than the Minamisoma Mano-Migita-Ebi solar power plant, which was the largest in Fukushima Prefecture until 2019 and is made up of 220,000 solar panels that, if laid end to end, would cover 350 kilometers — roughly the distance between Nagoya and Tokyo. The panels can generate up to 60 megawatts of electricity, enough to power 20,000 households.

Because of projects like the Minamisoma facility, Fukushima Prefecture has claimed the crown as the Tohoku region’s leader in cumulative solar power generation since 2013, and this is a direct consequence of the reconstruction policies that were put in place after the March 2011 earthquake, tsunami and nuclear disaster.

But today, grid connection issues, opposition by incumbent energy companies and a return to nuclear energy in some parts of the country are slowing progress in Fukushima and beyond. In 2022 almost 80% of the increase in total electricity generation in Japan came via fossil fuels — a worrying signal that, although renewable energy generation continues to increase, it is not keeping up with the pace of electrification.

Renewable recovery

Particularly in the coastal areas of Fukushima Prefecture, solar panels have a strong presence: They cover fields, occupy clearings that have been carved out of forests and hillsides, and rest on the rooftops of houses. Cars and trucks brandishing the names of the companies that operate them are a regular feature as they carry equipment and workers along well-kept roads…………………………………………………………………………………………………………………….

“Recovery plans have always been tied to developing a society that is no longer dependent on nuclear power,” says Masaki Moroi, deputy director of Fukushima Prefecture’s Energy Division.

By the end of 2021, Fukushima Prefecture had covered 47% of its energy demand with renewables, compared with just 23.7% in 2011. That’s a particularly impressive feat when compared with Japan’s national average of just 22.7% in 2022.

“Fukushima took the lead after 2011 because of its direct experience with disaster and clear commitment by policymakers to quit nuclear energy and back renewables,” says Hikaru Hiranuma of the Tokyo Foundation for Policy Research.

According to Hiranuma, the single most influential policy in the initial boom in renewable energy was the introduction of a feed-in-tariff program by the Ministry of Economy, Trade and Industry in July 2012………………………………………………………………………………………..

Beyond Minamisoma, Fukushima Prefecture implemented policies promoting renewable energy projects in areas affected by the tsunami and nuclear fallout where there were high rates of abandoned land………………………………………………………………………………………………………………………. more https://www.japantimes.co.jp/environment/2023/09/05/fukushima-renewable-energy-leader/

Focus on renewables, not nuclear, to fuel Canada’s electric needs

Relying on nuclear power goes against the evidence. The smart money is on renewables. Solar and wind energy make much more sense.


Policy Options, by Martin Bush, September 1, 2023

The demand for electricity continues to rise as countries transition to an electrified economy. To ensure an adequate and reliable supply during peak hours, governments must decide which energy technologies should be prioritized and developed to help with this transition.

Nuclear power is certainly in the running for providing this essential service, but it’s not the best option. Refurbishing aging CANDU reactors and investing in unproven nuclear technology, such as small nuclear reactors (SMRs), will waste money that could otherwise be invested in renewable energy solutions.

That’s where the smart money is – renewables – and all the evidence points to why.  Electricity from nuclear energy is too expensive.

According to the World Nuclear Industry 2022 Status Report, nuclear energy’s share of global electricity generation in 2021 was 9.8 per cent – its lowest level in four decades – and substantially below its peak of 17.5 per cent in 1996.

Nuclear energy is being outpaced by non-hydro renewables, which in 2021 increased their share of global power generation to 12.8 per cent.

Between 2009 and 2021, utility-scale solar energy costs plummeted by 90 per cent, while similar wind energy costs dropped by 72 per cent. In contrast, nuclear costs increased by 36 per cent.

The cost of electricity generated by solar and onshore wind is in the range of 2.4 to 9.6 U.S. cents per kilowatt hour, (¢/kWh) while the cost of electricity from nuclear is estimated as anywhere between 14 and 22 ¢/kWh. It’s not even close.

In 2021, total investment in non-hydro renewable electricity capacity reached a record US$366 billion, 15 times the reported global investment in nuclear power plants of US$24 billion. Investments in solar energy were 8.5 times and wind six times the investments in nuclear energy.

Globally, the cost of renewable-produced electricity is now significantly below not only nuclear power but also gas. According to an analysis by Bloomberg New Energy Finance, wind and solar power are now the cheapest form of new electricity in most countries, including Canada. Bloomberg anticipates it will be more expensive to operate existing coal or fossil gas power plants within five years than to build new solar or wind farms.

Unsurprisingly, it is wind farms and large solar installations that are being built in record numbers……………………………………………………………………………………… more https://policyoptions.irpp.org/magazines/september-2023/renewables-not-nuclear-electric-canada/

French energy regulator: Nuclear alone not enough for carbon neutrality

“renewable energies to be brought on stream as quickly as possible, as there will be no new reactors in operation by 2035” to meet the need to decarbonise the energy mix.

By Clara Bauer-Babef and Paul Messad | EURACTIV.fr 27 Aug 23  https://www.euractiv.com/section/politics/news/french-energy-regulator-nuclear-alone-not-enough-for-carbon-neutrality/

If France is to achieve carbon neutrality by 2050, it must integrate renewables into its energy mix, according to the head of the country’s energy regulator, RTE, who believes nuclear power alone will not be enough.

As part of its EU targets, France has pledged to become carbon neutral by 2050 and contribute to the bloc’s efforts to cut greenhouse gases by 55% by 2030.

“To achieve carbon neutrality by 2050, nuclear power alone will not be enough,” said Xavier Piechaczyk, Chairman of RTE, on France Inter radio on Saturday.

Instead, France needs to diversify further its energy mix, which is currently 40% nuclear, 28% oil, 16% natural gas, 14% renewables and 2% coal, according to the French Ministry for Ecological Transition.

All the more so as “energy consumption will fall, but electricity consumption will rise to replace fossil fuels”, with a 25% increase in decarbonised electricity, writes RTE in its reference report on the French energy mix in 2050.

As such, Piechaczyk calls for “renewable energies to be brought on stream as quickly as possible, as there will be no new reactors in operation by 2035” to meet the need to decarbonise the energy mix.

France plans to build six new small nuclear reactors (EPR), although these will not be operational until 2035. Construction for the first reactor is only set to start in 2027.

“France is struck by a pathology, which is to spend its time arguing between nuclear versus renewable: it’s not the first question to be asked”, Piechaczyk said.

Piechaczyk referred in particular to the conflict between the radical left and ecologists, who are opposed to nuclear power,  and the presidential majority and the right, supported by the Communists, who favour the development of nuclear power.

Power-starved North Korea turns to solar energy to keep the lights on

1North Korea is increasingly turning to solar power to help meet its energy
needs, as the isolated regime seeks to reduce its dependence on imported
fossil fuels amid chronic power shortages. Prices of solar panels have
dropped in recent years thanks to an influx of cheap Chinese imports and a
rise in domestic assembly of panels within North Korea, according to the
Stimson Center think-tank in Washington.

This has allowed many North
Koreans to install small solar panels costing as little as $15-$50,
bypassing the state electricity grid that routinely leaves them without
reliable power for months. Larger solar installations have also sprung up
at factories and government buildings over the past decade.

Military interest in nuclear-powered space travel, but solar-powered is just as good, -and safer.

2 Government, Industry Explore Nuclear, Solar Space Engines

COLORADO SPRINGS, Colorado — More commercial and military activity is taking place in space, and the Defense Department and industry are investing in emerging propulsion technologies to move systems in orbit faster, farther and more efficiently.

……………………………………..In 2021, the Defense Advanced Research Projects Agency selected Lockheed Martin as one of three prime contractors — along with General Atomics and Blue Origin — for Phase 1 of its Demonstration Rocket for Agile Cislunar Operations, or DRACO, program to showcase the potential of a nuclear thermal propulsion system in space, a DARPA release said.

This January, NASA announced it had partnered with DARPA on the DRACO program, describing a nuclear thermal rocket engine as “an enabling capability for NASA crewed missions to Mars.” The goal is to demonstrate the system in orbit in fiscal year 2027, with the Space Force providing the launch vehicle for the DRACO mission, a DARPA statement said.

The program is about to enter Phase 2, which “will primarily involve building and testing on the non-nuclear components of the engine” such as valves, pumps, the nozzle and “a representative core without the nuclear materials in it,” DARPA’s program manager for DRACO Tabitha Dodson said during a panel discussion at the Space Foundation’s Space Symposium in April. Dodson said then a Phase 2 decision is “quite close.” However, at press time in mid-July, no contracts have been awarded.

…………………………………“There are no facilities on Earth that we could use for our DRACO reactor’s power test … so we’ve always baselined doing our power test for the reactor in space,” Dodson said. Once in space, DARPA will “very gradually” ramp up the system to “full power thrust,” she said…………………………………………………………………………………………………………………………………………
Despite DARPA’s commitment to safety, nuclear propulsion systems face an uphill battle getting deployed on spacecraft at scale, said Joel Sercel, founder and CEO of TransAstra, a space technology company.

………………………………………………………………………………..In May, the Space Force awarded TransAstra a Phase One Small Business Innovation Research contract to explore new applications for the company’s propellant-agnostic Omnivore thruster.

The Omnivore thruster uses solar reflectors to focus sunlight onto a solar absorber, which then superheats the system’s propellant to generate thrust “typically six times faster and eight times cheaper than electric systems,” a company release said.

Additionally, TransAstra calculated an Omnivore thruster “using liquid hydrogen propellant … will perform similarly to nuclear rockets, but without nuclear materials, costs or risk.”

Sercel said Omnivore has “80 percent of the performance of nuclear at 1 percent of the cost.” The system is essentially nuclear powered, “but the nuclear reactor in question is the fusion reactor at the center of the solar system called the Sun,” he added.

“The nice thing about nuclear reactors is that you have a small, compact reactor versus large deployable solar reflectors, but the basic performance of solar thermal rockets and nuclear rockets is about the same,” he said. And with Omnivore “you don’t have all these safety concerns and radioactive material and reactor control issues and so on. So, we think it’s a much more practical approach.”

Omnivore could have multiple mission applications for the Defense Department, Sercel said. Using liquid hydrogen propellant, the thruster “can deliver hundreds of kilograms” of spacecraft to geosynchronous orbit “on small launch vehicles, and the Space Force seems to be very excited about this,” he said. The system could also deliver spacecraft weighing more than 100 kilograms to cislunar space, he said.

Additionally, TransAstra has an Omnivore variant that uses water as the propellant, the solar absorber superheating the water vapor and releasing the gas through a nozzle to generate thrust.

The water-based variant can be placed on the company’s Worker Bee small orbital transfer vehicles, about 25 of which can fit on a single Falcon 9 rocket, Sercel said.

“Each [Worker Bee] could deliver up to six small [satellites] to their orbital destinations. So, we can deliver a full constellation of 100 small or micro [satellites] to all different inclinations, and you would get global coverage in one launch.”…………………………………………………………more https://www.nationaldefensemagazine.org/articles/2023/7/31/government-industry-explore-nuclear-solar-space-engines

Old Nuclear Weapons Sites Targeted for Clean Energy Projects.

Daniel Moore, 28 Jul 23 https://news.bloomberglaw.com/environment-and-energy/former-nuclear-weapons-sites-targeted-for-clean-energy-projects

  • Agency identifies 70,000 acres at five weapons sites
  • DOE land could host largest US solar farm at Hanford Site

The Energy Department plans to turn some of its Cold War nuclear weapons development sites into grounds for clean energy generation, including what could be the largest US solar project, agency leaders announced Friday.

The department has identified about 70,000 acres at five sites that hosted nuclear weapons development and testing and have since been cleaned up, according to details of the announcement shared in advance with Bloomberg Law. The announcement is part of the agency’s new Cleanup to Clean Energy initiative, an effort to repurpose parts of DOE-owned lands into clean energy generation sites.

“It’s a good deal and a huge opportunity,” Energy Secretary Jennifer Granholm said at the outset of a daylong event with clean energy industry representatives held in an auditorium space at the agency’s headquarters in Washington.

Developers would have a unique opportunity to lease land from the Energy Department, Granholm said. The sites have massive tracts of land whose characteristics are already mapped out. The decades of site analysis and remediation would speed up environmental and permitting reviews, too.

“Therefore, it will take less time to get shovels in the dirt,” Granholm said.

One former nuclear testing facility, the Hanford site in Richland, Wash., has the potential to host the largest solar farm in the country, Granholm said.

Another site, the Idaho National Laboratory in Idaho Falls, Idaho, sprawls 890 square miles and purchased about 50 megawatts of power in fiscal year 2020 to support 5,400 employees, 600 vehicles, and 300 buildings and trailers, according to the agency. The other sites under consideration include: Nevada National Security Site, in Nye County, Nev.; the Savannah River Site, in Aiken, S.C.; and the Waste Isolation Pilot Plant, near Carlsbad, N.M.

The agency’s Office of Environmental Management, Office of Legacy Management, Office of Nuclear Energy, and National Nuclear Security Administration all worked to locate the best sites.

The industry officials included those “with proven experience in implementing successful clean electricity projects generating 200 MW or larger,” according to the department.

After the panel, DOE officials told reporters they’re looking forward to project proposals that could power not just DOE facilities but the surrounding region.

Power generators could even propose an arrangement with a customer—a hydrogen producer, semiconductor manufacturer, or other type of facility, said Katy Huff, assistant secretary for the Office of Nuclear Energy.

At the Hanford site, the biggest nuclear cleanup site in the country, “there are certainly plenty of developers who have expressed interest” but the department hasn’t made any decisions, said Ike White, who leads the Office of Environmental Management.

“The department is just opening up this for ideas,” White said, adding the agency is open to a range of clean energy technologies.

Not nuclear, but wind and solar still cheapest – CSIRO

By Peter Roberts https://www.aumanufacturing.com.au/not-nuclear-but-wind-and-solar-still-cheapest-csiro 18 July 23

There is a huge amount of hype around new energy sources to replace fossil fuels and none more so than the phenomenon of small modular nuclear reactors (SMR).

But the hype remains just that according to the latest GenCost 2022–23 study released today by CSIRO and Australian Energy Market Operator.

While SMRs are likely cheaper to build that traditional large nuclear power stations, renewable power from onshore wind turbines and solar PV are increasingly important as the cheapest sources of new energy generation capacity according to the report.

This holds true whether the costs of integration into the grid are taken into account, or not.

Each year the two bodies work with industry to give an updated cost estimate for large-scale electricity generation in Australia, and each year wind and solar come out on top

The 2022-23 report found that onshore wind and solar PV are ‘the lowest cost generation technology by a significant margin’, despite cost increases averaging 20 per cent for new-build electricity generation in Australia.

Offshore wind is higher cost but competitive with other alternative low emission generation technologies.

CSIRO Chief Energy Economist Paul Graham said: “Innovation in electricity generation technology is a global effort that’s strongly linked to climate change policy ambitions.

“Technology costs are one piece of the puzzle, providing critical input to electricity sector analysis.

“To limit emissions, our energy system must evolve and become more diverse.”

GenCost said the next lowest cost flexible technology in 2023 is gas generation with carbon capture and storage, but only if it could be financed at a rate that does not include climate policy risk.

Fossil fuels were more expensive and faced hurdles such as government legislation and net zero targets, and historically high energy costs.

GenCost said that with SMRs, ‘achieving the lower end of the nuclear SMR range (of cost estimates) requires that SMR is deployed globally in large enough capacity to bring down costs available to Australia’.

As for SMRs, none of this should not be surprising as even the International Atomic Energy Agency does not claim nuclear power is cheaper.

The agency claims only that SMRs, advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit or about one-third of typical sizes, provide cheaper power than traditional large nuclear stations.

Their advantage over traditional nuclear is linked to the nature of their design – small and modular.

According to the IAEA more than 70 commercial SMR designs are being developed around the world.

The IAEA says on its website: “Though SMRs have lower upfront capital cost per unit, their economic competitiveness is still to be proven in practice once they are deployed.”

Welsh campaigners call for Wylfa to be at heart of Ynys Mon ‘green energy’ island

 Campaigners from several organisations opposed to new nuclear power
developments in Wales have written to Climate Change Minister Julie James
calling for the Welsh Government to acquire the Wylfa site as a national
asset to develop a range of cutting-edge renewable energy technologies.

Last week, the Welsh Affairs Committee in Westminster called on the British
Government to acquire the former nuclear power plant site at Wylfa to
redevelop for nuclear power, but, in their response, ministers indicated
that it was a ‘commercial decision’ for Hitachi, the owners of the
site, to determine who they sell the site to.

Anti-nuclear activists
believe this represents an opportunity for the Welsh Government to approach
Hitachi to see if they can purchase the site to become the hub of an Ynys
Mon (Anglesey) that is truly a ‘green energy island’. This would be in
line with Cardiff’s aspiration to ensure that all electricity consumed in
Wales is from renewable sources by 2035, and that such generation should be
ramped up in line with demand in the future.
