TIDAL power extinguishes the arguments for new nuclear plants in Suffolk

Ian Blackford rubbishes case for Sizewell C on Question Time, The National, By Hamish Morrison 18 Nov 22

The SNP Westminster leader told the BBC Question Time audience in Suffolk – where the new Sizewell C nuclear plant will be built – he was “delighted” to assist them in objecting to the project.

It came on the same day the Chancellor confirmed the £30 billion project was going ahead as he announced the first £700 million contracts would be signed within weeks.

Citing a Royal Society report from 2021 which found the UK is capable of generating 11GW of tidal power by 2050 – 50% greater than current nuclear capacity, Blackford said: “We can produce safe, green energy, we don’t need nuclear.”

Blackford said the potential amount of energy that could be generated through tidal power – which generates electricity with waves in the sea – would be enough to meet the basic amount of demand for the UK.

And the technology, which uses underwater turbines to generate electricity, has the potential to support far more jobs in the country than does nuclear, Blackford added.

He said: “Between now and 2050, we could increase fivefold our green energy output in Scotland…………………………..

“Look at the Royal Society report, we don’t need nuclear because you can get the baseload from tidal.

“And if I can assist those that are objecting to Sizewell here [Suffolk], then I’d be delighted to do so. It’s expensive, it is a white elephant, we can produce safe, green energy we don’t need nuclear.”  https://www.thenational.scot/news/23135460.ian-blackford-rubbishes-case-sizewell-c-question-time/

India headed towards 100% renewables power by 2050

A new optimistic Nature paper from the LUT University in Finland looks to a
key role being played by renewables for rapid transitioning of the power
sector across states in India. Progress has been uneven at times, but LUT
says that a renewables-based power system by 2050 could be ‘lower in cost
than the current coal dominated system’ and have ‘zero greenhouse gas
emissions’ while providing ‘reliable electricity to around 1.7 billion
people’.

Renewable energy brings record savings to Europe

Renewable energies have allowed the European Union to avoid €99bn in
fossil gas imports since the beginning of the war in Ukraine, with an
increase of €11bn compared to last year thanks to record growth in wind
and solar capacity, according to a new report.

Low operating costs make the case for investing in utility-scale renewable projects

 Renewables met 100% of global electricity demand growth during the first
half of 2022. So says the ‘Global Electricity Mid-Year Insights 2022’
from Ember, a global energy think tank. In fact, it says there was a 389
TWh increase in the demand for electricity in the first half of 2022
compared to the first half of 2021, whereas the rise in renewables supply
was actually a bit more – 416TWh.

That’s not surprising given that
renewables are getting so cheap- including in the UK, with wind and solar
the most prolificate new sources across world. However, that in turn may
create a bit of a problem for older renewables, set up under quite
lucrative subsidy schemes, based on now high gas prices, like the
Renewables Obligation in the UK. As I have noted in earlier posts, there is
pressure on them to switch to the more competitive CfD system. Certainly
the RO system is based on adding a subsidy to wholesale gas prices, so
something has to change, since gas prices are now so high. But there are
issues- will every supplier be happy to accept less earnings? They may drag
their feet.

The record-breaking run in power prices, particularly in
Europe, is creating a favorable investment case for solar and wind
projects, making it increasingly compelling to develop renewable assets
purely based on project economics. According to Norwegian consultancy
Rystad Energy, current spot prices in Germany, France, Italy, and the
United Kingdom would all result in payback of 12 months or less.
Considering the average monthly spot prices for August in these countries
were all well over €400/MWh and the relatively low operating costs of
renewables, investing in utility-scale projects appear to be a no-brainer.

Renewables need minerals. Can their pollution and public health challenges be overcome?

 https://beyondnuclearinternational.org/2022/10/09/renewables-need-minerals/ By Linda Pentz Gunter,  by beyondnuclearinternational,

We are now both on the path to — and amidst the crisis of — resolving our past greed and irresponsibility in the energy and transport sector. But few, if any, human industries are without a carbon footprint. This has made the climb out of our carbon-intensive paradigm all the harder. 

Consequently, our first imperative — in order to do as little current or future environmental harm as possible — is to focus on solutions that have the lowest carbon footprint and environmental and human impact. This puts conservation at the pinnacle of our priorities, followed by energy efficiency. 

Particularly in developed countries — where we bear almost the entire responsibility for the mess we have made of our planet — we can, and must, consume less, become more energy efficient, live in smaller homes, use public transport routinely, walk and bicycle more and drive and fly less.

Using fossil fuels has to stop. Completely. And ideally now, but, realistically, as soon as possible. Replacement power will still be needed. But nuclear power, which creates long-lived lethal radioactive waste from the beginning to the end of its fuel cycle, and, as a large thermo-electric generator, relies on huge quantities of what will become increasingly scarce water supplies, is not the substitute for fossil fuels. Nuclear power cannot be an environmentally clean and just energy solution. And it has no answers for the transport sector, either.

Yet, as we decry the extraction of uranium — and all its attendant poisoning of the environment and ourselves along with human rights violations — we are met with the legitimate argument that increasing the use of renewables (and electric cars) in order to decarbonize, brings with it the same extractive environmental impacts.

But are they really the same? If we dig deeper, to use an unwelcome metaphor, we find parallels but not necessarily equity between the impacts of renewables and nuclear. This does not excuse or justify worker abuse, human rights violations or extractive contamination in any sector. But it’s an important distinction. 

First and foremost, we must look to carbon emissions. It makes sense, even if all the other downsides were equal — which they clearly are not — to at least focus on the lowest carbon emitters. And those are unquestionably renewables. Therefore, our responsibility now is to put things right in the renewable energy industry, even as we must point out, criticize and urge change in those areas that need improvement, including recycling, sustainable sourcing and human rights.

A second priority, is the ability and willingness of industries to make those improvements. 

We have seen how the wind industry has worked to minimize its impacts on migratory birds. It’s no coincidence that some of the biggest bird conservation groups, including BirdLife International, the American Bird Conservancy and the Audubon Society, cautiously support the development of wind power while scrupulously watchdogging its progress.

The renewable energy and electric vehicle industries recognize the fact that they rely on mineral extraction and, as such, must try to mitigate or avoid negative environmental, social and human rights impacts. Unlike the nuclear industry — which has been guilty of environmental and human rights abuses since it began — the renewable energy industry is working to resolve these significant drawbacks.

As Justine Calma wrote in The Verge at the end of last year: “There are ways to get the minerals the clean energy revolution needs while minimizing the impact on people and the planet. Startups are figuring out how to get better at recycling lithium batteries.” Mining companies are also looking to power their extraction using renewables rather than fossil fuels.

The World Bank program — The Climate-Smart Mining Initiative — aims to help “resource-rich developing countries benefit from the increasing demand for minerals and metals, while ensuring the mining sector is managed in a way that minimizes the environmental and climate footprint as it works to decarbonize”.

The nuclear industry, by contrast, has made no such effort to mitigate its environmental impact, and cannot do so, because splitting the atom to boil water is inherently dangerous and polluting. Worse, the industry actively pushes back against — or outright rejects — mitigation efforts because it would cost the already financially struggling nuclear sector money it can’t afford to expend if it is to stay in business.

The end product of nuclear power is long-lived highly radioactive waste with no long-term, safe, permanent management solution. While the renewable energy sector is looking into the recycling of batteries, there is no recycling of nuclear waste. Reprocessing — often misleadingly called “recycling” — does no such thing. 

In separating out the uranium and plutonium from irradiated reactor fuel, reprocessing produces even higher volumes of largely “low” and “intermediate”-level radioactive wastes, discharged into the air and sea or stored indefinitely.

The mining of uranium for use in nuclear power leaves behind radioactive waste and heavy metals that persistently contaminate the local environments, harming the health and safety of those communities and that of their land and water resources.

Nevertheless, there is no getting around the reality that the renewable industry, too, requires mining of minerals and rare earth metals, and that recycling, while beneficial, is not always done sustainably.

These hurdles are laid out in detail in a useful report prepared for Earthworks by the Institute for Sustainable Futures — Responsible minerals sourcing for renewable energy (Dominish, E., Florin, N. and Teske, S., 2019, Responsible Minerals Sourcing for Renewable Energy. Report prepared for Earthworks by the Institute for Sustainable Futures, University of Technology Sydney.) 

The report emphasizes that “recycling and responsible sourcing are fundamental to improving the sustainability of the renewable energy transition”.

However, it points out that while “the renewable energy and battery industries have made significant improvements to the efficiency of technologies, to improve performance, minimize demand for materials and reduce production costs,” attention to stewardship and human rights abuses has been less promising. “The industry experts interviewed noted that reducing the environmental and social impacts of supply is not a major focus of the renewable energy industry.”

Inevitably, many of the resources for the renewable energy industry (along with electric vehicles, not discussed here as these are outside our energy focus), are to be found in troubled parts of the world — most notably DR Congo. In turn, the manufacturing of those minerals into metals is largely carried out in China, where human rights are suppressed.

The impacts of mining to supply the renewable energy industry invariably result in “pollution and heavy metal contamination of water and agricultural soils, and health impacts on workers and surrounding communities”.

The wind energy industry emerges as the least offender, according to the report. “Material use for wind turbines is already very efficient. Recycling of bulk materials (steel, aluminium, copper) used in wind turbines is well established with high recycling rates.”

The report offers some glimmers of hope, noting that increased use of renewables means a reduction in coal mining, “which is responsible for the greatest number of fatalities, health and environmental issues.”

But we are undoubtedly now in the land of Faustian bargains. We have left it too late to make choices that are problem-free. Renewables, therefore, must be measured up against the alternatives and nuclear power isn’t one of them. Aside from the carbon footprint and human rights violations of nuclear power, and its high costs and long construction times, we must also factor in the lethal waste; the daily radioactive releases harming primarily children; the outcome of a catastrophic accident; and the inextricable link to nuclear weapons development, to name a few.

We must learn to live more simply; smaller. More quietly. Tread lightly. And yes, we must transition to renewables, energy efficiency and conservation, not tomorrow, not gradually, but immediately. Can we do it without leaving yet another mess? Without further abuses?

As the ISF study concludes, not yet, but we are getting there. “There are a large number of responsible sourcing initiatives that promote environmental stewardship and the respect of human rights in the supply chain, most of which are voluntary and industry-led,” the authors wrote. “If these initiatives are harmonized and widely adopted, it may lead to more responsible supply chains.”

Until then, renewables are our least worst power option, and, out of time as we are, it’s a choice we have brought upon ourselves.

A Nebraska county of only 625 people contained nearly 100 deep underground nuclear missiles, so the US Air Force halted a green-power project that would have revitalized its economy

MSN lvaranasi@insider.com (Lakshmi Varanasi) 22 Sept 22,

  • There are hundreds of underground nuclear missiles across Colorado, Nebraska, Wyoming, North Dakota, and Montana. 
  • The US Air Force says wind turbines can’t be constructed within a 2-mile radius of these missiles.
  • Due to underground missiles, a wind turbine project in Banner County, Nebraska, was limited in scope.

The Democrats’ new climate and tax bill will invest billions in clean energy. Here are 21 high-paying green careers for people who want to save the planet. (Business Insider)

  • There are many occupations out there that help the environment, such as wind turbine service technician.
  • The Inflation Reduction Act could mean more clean energy jobs created.
  • Here are the 21 fastest-growing green jobs that also have an annual pay greater than the overall median pay.

Saving the earth and having a lucrative career aren’t always mutually exclusive, and the Democrats’ big climate and tax bill that just passed could mean even more investment in green jobs.

The Inflation Reduction Act could mean many more workers will be needed to fill various clean energy and other jobs in the coming years. The bill also says it will cut carbon emissions by about 40% by 2030……………………………… (Read the original article on Business Insider)

In Nebraska’s Banner County, the remains of Cold War America are buried right below the surface. 

During the 1960s, when the US was locked in a nuclear stalemate with the then-Soviet Union, it began planting hundreds of nuclear missiles across rural swaths of the country like Colorado, Nebraska, Wyoming, North Dakota and Montana in case it needed to shoot them into the enemy camp at a given moment. 

Now, those missiles are preventing the region from harnessing its most valuable resource: strong, gusty winds.

The Flat Water Free Press, an independent news outlet in Nebraska, reported last week that in 2019, the US Air Force began to thwart a wind turbine project in the state’s southwest Banner County. 

Two renewable energy companies, Invenergy and Orion Renewable Energy Group, had singled out Banner for its “world class winds,” the Flat Water Free Press reported. They were ready to construct a combined 300 turbines across the region. 

Each turbine would have brought in an additional $15,000 in annual income to the landowner whose property it would be built on. The capital from the turbines would have flushed into Banner’s school system and revitalized the 625-person county. 

But the Air Force contended that the turbines would pose a “significant safety hazard” to pilots — especially during storms or blizzards. The Air Force decided that the turbines needed to be constructed 2.3 miles away from each other to ensure that pilots had enough space to land without potentially digging their wheels into a missile. Until then, a quarter mile between each turbine was had been sufficient.

 “The new guidelines, explained to residents earlier this spring, significantly cut the number of possible turbines that could be constructed.”

Banner’s residents have been left frustrated and disillusioned by the Air Force’s new guidelines. “This resource is just there, ready to be used,” one Banner landowner said. “”How do we walk away from that?” Read the full story by The Flat Water Free Press here.  https://www.msn.com/en-us/news/us/a-nebraska-county-of-only-625-people-contained-nearly-100-deep-underground-nuclear-missiles-so-the-us-air-force-halted-a-green-power-project-that-would-have-revitalized-its-economy/ar-AA126fRl?li=BBnbcA1

It was set to be Nebraska’s largest wind project. Then the military stepped in.

Flatwater Free Press. By Natalia Alamdari, 16 Sept 22,

“…………………….. With about 150,000 acres leased by energy companies, this county of just 625 people stood poised to become home to as many as 300 wind turbines. 

It would have been the largest wind project in the state, bringing in loads of money for the landowners, the developers, the county and local schools.

But then, an unexpected roadblock: The U.S. Air Force.

Under the dusty fields of Banner County are dozens of nuclear missiles. Housed in military silos dug more than 100 feet into the ground, the Cold War relics lie in wait across rural America, part of the country’s nuclear defenses.

For decades, tall structures like wind turbines needed to be at least a quarter mile away from the missile silos.

But earlier this year, the military changed its policy. 

Now, they said, turbines now can’t be within two nautical miles of the silos. The switch ruled out acres of land that energy companies had leased from locals — and wrested a potential windfall from dozens of farmers who’d waited 16 years for the turbines to become reality.

The stalled Banner County project is unique, but it’s one more way that Nebraska struggles to harness its main renewable energy resource.

Oft-windy Nebraska ranks eighth in the country in potential wind energy, according to the federal government. The state’s wind energy output has improved markedly in recent years. But Nebraska continues to lag far behind neighbors Colorado, Kansas and Iowa, all of whom have become national leaders in wind.

The Banner County projects would have grown Nebraska’s wind capacity by 25%. It’s now unclear how many turbines will be possible because of the Air Force’s rule change.

“This would have been a big deal for a lot of farmers. And it would have been an even bigger deal for every property owner in Banner County,” Young said. “It’s just a killer. Don’t know how else to say it.”

LIVING WITH NUKES………………………..

Today, there are decommissioned silos scattered throughout Nebraska. But 82 silos in the Panhandle are still active and controlled 24/7 by Air Force crews.

Four hundred intercontinental ballistic missiles — ICBMs — are burrowed in the ground across northern Colorado, western Nebraska, Wyoming, North Dakota and Montana. The 80,000-pound missiles can fly 6,000 miles in less than a half-hour and inflict damage 20 times greater than the bombs dropped on Hiroshima in World War II.

“If we ever get bombed, they say this is the first place they’re going to bomb, because of the silos that we’ve got here,” said farmer Tom May.

Every acre of May’s property sits within the two miles of a missile silo. Under the new Air Force rule, he can’t put a single wind turbine on his ground……….

Banner County had what developers called “world-class wind.” Many landowners were eager – signing away their acres came with the promise of roughly $15,000 per turbine per year. The turbines were also going to pump money into the county and school system, said county officials and company executives.


“In Banner County, it would have reduced property taxes to damn near nothing,” Young said they were told.

Eventually, two companies – Invenergy and Orion Renewable Energy Group – finalized plans to put up wind turbines in Banner County. 

Environmental impact studies were completed. Permits, leases and contracts were signed. 

Orion had 75 to 100 turbines planned, and hoped to have a project operating by this year. 

Invenergy was going to build as many as 200 turbines. The company had qualified for federal tax credits to start the project and had even poured the concrete pads that the turbines would sit upon, covering them back up with earth so farmers could use the land until construction began. 

But discussions with the military starting in 2019 brought the projects to a screeching halt. Wind turbines pose a “significant flight safety hazard,” an Air Force spokesman said in an email. Those turbines didn’t exist when the silos were built. Now that they dot the rural landscape, the Air Force said it needed to reevaluate its setback rules. The final number it settled on was two nautical miles —  2.3 miles on land …….

…………………………………… For most landowners, the news came as a gutpunch. They said they support national security and keeping service members safe. But they wonder: Is eight times as much distance necessary?

“They don’t own that land. But all of a sudden, they have the power to strike the whole thing down, telling us what we can and can’t do,” Jones said. “All we’d like to do is negotiate. 4.6 miles [diameter] is way too far, as far as I’m concerned.”

………………………………………. By 2010, Nebraska was 25th in the country at producing wind-generated power — the bottom of the pack among windy Great Plains states.

The reasons fueling the lag were uniquely Nebraskan. Nebraska is the only state served entirely by publicly owned utilities, mandated to deliver the cheapest electricity possible.

Federal tax credits for wind farms only applied to the private sector. With a smaller population, already cheap electricity and limited access to transmission lines, Nebraska lacked the market to make wind energy worthwhile.

A decade of legislation helped change that calculus. Public utilities were allowed to buy power from private wind developers. A state law diverted taxes collected from wind developers back to the county and school district — the reason the Banner wind farms may have shrunk taxes for county residents………………………………..

John Hansen, president of the Nebraska Farmers Union, said pushback over wind farms has ramped up in recent years. But it’s a loud minority, he said. Eighty percent of rural Nebraskans thought more should be done to develop wind and solar energy, according to a 2015 University of Nebraska-Lincoln poll……………

“This resource is just there, ready to be used,” Brady Jones, John Jones’ son, said. “How do we walk away from that? At a time when we’re passing legislation that would vastly increase investment in wind energy in this country? That energy’s got to come from somewhere.” https://flatwaterfreepress.org/it-was-set-to-be-nebraskas-largest-wind-project-then-the-military-stepped-in/

World’s richest countries fall short on renewable energy targets

Eleven of the 20 largest economies got a C or worse on a renewable energy report
card, which assessed their plans to reach net zero and their targets for
producing and using renewable energy. Most of the world’s 20 largest
economies, known as the G20, lack ambitious renewable energy targets or are
falling short of their climate commitments, according to a report by
climate and renewable energy advocacy groups.

The G20, which includes 19 countries and the European Union (EU) and Spain as a permanent guest, is
responsible for around 80 per cent of global energy-related emissions. This
gives the group significant responsibility to reduce emissions as well as
influence over the world’s pace to decarbonise, says Mike Peirce at the
Climate Group, a UK nonprofit that advocates for climate action.

Peirce, along with others from the Climate Group and a renewable energy research
group called REN21, analysed data on renewable energy development within
G20 countries to rank their progress towards renewable energy goals. A
“sustainable energy transition” is a top priority to be discussed
during the G20’s annual conference in Bali in November.

Australian Capital Territory consumers reap rewards of 100 pct renewables as wind and solar farms hand back windfall profits.

The ACT is the only region of Australia’s main grid spared from sharp
increases in electricity bills, and its consumers can thank the shift to
100 per cent renewables and the structure of their deals with wind and
solar farms.

The ACT government has written contracts with 11 wind and
solar farms to provide the equivalent amount of electricity consumed by
homes and businesses in the ACT each year. The nature of these deals –
called contracts for difference (CfDs) – means that if the wholesale market
trades below the agreed strike price, the government (and consumers), top
up the difference to the wind and solar farms.

But if the wholesale prices are above the strike price – as they have been by a big distance over the
last six months – then the wind and solar farms must return these windfall
gains to ACT consumers. And in the last quarter, as wholesale prices soared
to record highs – and an average of more than $300/MWh in NSW – the wind
and solar farms paid back a total of $58 million to electricity consumers
in the ACT, shielding them from any significant bill hikes.

What’s the real price tag for renewable energy for the planet?

A new Stanford study calculated the cost of global renewable energy would
be $62 trillion (yes, with a “t”). But the big upfront investment would
create jobs, drastically reduce carbon emissions, and pay for itself in
just six years.

It was hot this summer—record-shatteringly hot, in many
places. And the extreme heat around the world in the last few months is
only one symptom of the climate change caused by greenhouse gasses, which
are released into the atmosphere when fossil fuels like coal and gas
burn—more extreme droughts, wildfires, flooding, storms, and unseasonable
weather patterns are also symptoms.

Unless we significantly curb how much
coal and gas we burn in the next few decades, scientists are pretty much in
agreement that the consequences will keep getting more severe.

One of the simplest ways to cut back greenhouse gas emissions is in how the
electricity we use is generated. Even though the current system is
dominated by coal, oil, and natural gas, the technology for producing
energy from renewable sources like wind, hydro, and solar is effective,
available, and increasingly economical.

A new study by Stanford engineer
Mark Jacobson and his team published in the journal Energy & Environmental
Science calculates that the world would need to spend around $62 trillion
to build up the wind, solar, and hydro power generating capacity to fully
meet demand and completely replace fossil fuels. That looks like a huge
number, even spread out across the 145 countries cited in the study.

But after crunching the numbers, estimates show that countries would make the
money back in cost-savings in a relatively short period of time: Between
one to five years. The study also projected that shifting to 100 percent
renewable energy generation would result in a net increase of over 28
million jobs when factoring in the fossil fuel industry jobs that would be
lost.

It also only requires 0.36 percent more land than is currently used
for energy generation, addressing two major concerns about switching from
fossil fuels to renewables. Making the shift, and soon, is important to
slow and limit planetary warming. The study called for 100 percent clean
energy by 2035 ideally, and 2050 at the latest, with an interim goal of 80
percent by 2030.

This lines up with the roadmap laid out in the UN’s most
recent climate report and the Paris Agreement, a 2015 international treaty
for climate action that includes reducing global emissions to net-zero by
2050 to avoid worst-case levels of warming.

Fast transition to renewables will save the world up to $12tn (£10.2tn) by 2050

Switching from fossil fuels to renewable energy could save the world as
much as $12tn (£10.2tn) by 2050, an Oxford University study says. The
report said it was wrong and pessimistic to claim that moving quickly
towards cleaner energy sources was expensive. Gas prices have soared on
mounting concerns over energy supplies. But the researchers say that going
green now makes economic sense because of the falling cost of renewables.

“Even if you’re a climate denier, you should be on board with what we’re
advocating,” Prof Doyne Farmer from the Institute for New Economic Thinking
at the Oxford Martin School told BBC News. “Our central conclusion is that
we should go full speed ahead with the green energy transition because it’s
going to save us money,” he said.

Plunging costs of renewable energy – as nuclear power costs increase

The tumbling cost of renewable energy means transitioning away from fossil
fuels over the next 30 years will save the world “at least $12 trillion”,
according to researchers at the University of Oxford.

The decarbonisation
of the energy system will not only see a major reduction in the cost of
producing and distributing energy, but will also allow for greater levels
of energy to be produced and therefore help expand energy access around the
planet.

The faster the transition to renewables occurs, the greater the
potential for savings, the team found, and urged governments to recognise
the enormous boost to the global economy, that abandoning fossil fuels will
bring about.

“There is a pervasive misconception that switching to clean,
green energy will be painful, costly and mean sacrifices for us all – but
that’s just wrong,” said Professor Doyne Farmer, who leads the team that
conducted the study at the Institute for New Economic Thinking at the
Oxford Martin School. The research team analysed thousands of transition
cost scenarios produced by major energy models and examined data on: 45
years of solar energy costs, 37 years of wind energy costs and 25 years for
battery storage.

They said the research reveals that the real cost of solar
energy dropped twice as fast as the most ambitious projections in these
models, revealing that, over the past 20 years, previous models “badly
overestimated the future costs” of renewable energy technology compared to
the reality of cheap renewables we are already seeing today.

The research also suggests nuclear power will play a diminishing role in the future
global energy mix due to the rising costs of building reactors. “The costs
of nuclear have consistently increased over the last five decades, making
it highly unlikely to be cost competitive with plunging renewable and
storage costs,” the researchers said. Meanwhile, the study showed the costs
for storage technologies, such as batteries and hydrogen electrolysis, are
also likely to fall dramatically.

Researchers agree: The world can reach a 100% renewable energy system by or before 2050

Oxford Brookes University , 09 August 2022

  New analysis of energy research by 23 scientists around the
world has concluded that the world can reach a 100% renewable energy system
by or before 2050.

The findings, explained in a recent paper On the History
and Future of 100% Renewable Energy Systems Research published by the IEEE
(Institute of Electrical and Electronics Engineers) are that such systems
can power all energy in all regions of the world at low cost. As such,
society will not need to rely on fossil fuels in the future.

In the early
2020s, there is growing scientific consensus that renewable energy
generated by solar panels and wind turbines and the associated
infrastructure will dominate the future energy system, and new research
increasingly shows that 100% renewable energy systems are not only feasible
but also cost effective. This provides the key to a sustainable
civilization and the long-lasting prosperity of humankind.

A concerted push now for renewable energy would save Britons billions of pounds

The UK would be paying “billions” of pounds less for its energy, if it had
stuck with plans to reduce fossil fuel use, an energy boss has said. Greg
Jackson, chief executive of Octopus energy, told the BBC there should be a
concerted push now. The same “sense of urgency” should be applied to the
switch to green energy, as there was for finding a Covid vaccine, he said.


The government said it had delivered a 500% increase in renewables since
2010. “Without the clean energy we have deployed over the past decade,
bills would be even higher today,” a spokesperson for the Department for
Business, Energy and Industrial Strategy (BEIS) said. There were already
plans to invest further in renewables, BEIS said.

In 2013, the coalition
government led by David Cameron made a series of changes, including cutting
back support for energy efficiency and later ended subsidies for onshore
wind. “If we hadn’t done that, energy bills this year would be billions of
pounds lower than they are,” Mr Jackson told the Big Green Money Show on
BBC Radio 5. “It’s short term behaviour that has left us even more exposed
than we need to be.”

Octopus Energy generates electricity from renewable
sources, including wind and solar and supplies energy to three million UK
customers. A report earlier this year by energy analysis site Carbon Brief
said bills in the UK were nearly £2.5bn higher than they would have been if
climate policies had not been scrapped over the past decade.

Expert forum Claverton Energy Group concludes that renewable energy +battery storage can meet UK’s needs – nuclear is not needed.

 Open University Professor Bill Nuttall’s updated version of his 2005 ‘Nuclear Renaissance’ book makes a case for nuclear power as low carbon and reliable, although, as the promotional blurb says, it accepts that
‘in recent years it has struggled to play a strong role in global plans for electricity generation in the 21st century’.

The new book also accepts that the much-hyped renaissance didn’t in the event happen- with Fukushima blowing it off course. Do we really want to build new nuclear plants to be ready on standby to provide spinning reserve backup and/or to provide rotational grid stability? Hydro can do that, and wind too to some extent, and virtual inertia can be provided by battery systems fed by PV solar.

Claverton Energy Group (CEG), a UK energy expert forum, has recently summarised some of the key conclusions of current research on energy system mixes and say they show that renewables can supply all our needs, with grid balancing provided in part by battery and heat storage.

Nuclear is not needed. The newly revised and updated 100% renewables global energy scenario produced by Prof Mark Jacobson and his team at Stanford University has come to similar conclusions, with 4 hour battery storage playing major balancing roles. All at competitive costs.
