Bitcoin’s electricity use is boundless. No wonder that Elon Musk etc now want nuclear power to fuel it.
Here’s what a modern massive Bitcoin mining operation in upstate New York looks like:
How Bitcoin is Heating This Lake and Warming the Planet more https://earthjustice.org/blog/2021-june/bitcoin-dirty-power?utm_source=facebook&utm_medium=social&utm_term=page&fbclid=IwAR30Z3V5q_FlRtyr1NnIZCQ6tU34tMs1AQUp8rgFRVGNTYaNoXl7I6Au8dg
Bitcoin is bringing dirty power plants out of retirement. Earthjustice is fighting this new trend in order to put an end to fossil fuels once and for all.By Ben Arnoldy | June 1, 2021 Seneca Lake in upstate New York is drawing attention to Bitcoin’s impact on the environment. A nearby Bitcoin mining plant is heating the lake waters — and the climate.
Bitcoin, the first and most famous cryptocurrency, is now burning through as much energy and pumping out as much greenhouse gas as entire nations.
Current estimates put the currency’s electricity usage on par with countries like the Netherlands. This is, shall we say, not helpful at a time when humanity is racing to switch to clean energy before we cook the planet.
In fact, Bitcoin’s energy demands are so high that the people who get rich from producing it want to pull dirty power plants out of retirement to power their operations. Earthjustice is urging regulators not to let that happen.
Bitcoins aren’t physical coins, so you might be asking why does a virtual currency require much energy?
The appeal of Bitcoin for some people is it allows them to trust no person, bank, or government. Bitcoin is entirely decentralized. But there needs to be some system to prevent fraudsters from making copies of the coins and trying to spend them twice.
To solve this, the system incentivizes many people rather than one trusted entity to devote computing power to validating transactions. The system is competitive, awarding new Bitcoins only to one “miner” who completes the validating and other tasks first, leading to an arms race of ever faster and more powerful computer rigs. While other cryptocurrencies use much less energy, Bitcoin’s particular solution to security without trust, it turns out, is extremely energy-intensive.
That monster requires a lot of energy to run the machines and to keep them from overheating. The cooling system for this rig uses cold water from Seneca Lake and discharges it back at temperatures reportedly as high as 98 degrees — with a permit to go even higher — harming trout and promoting algal blooms. For years, Bitcoin miners have sleuthed for places to set up shop where power is cheap and the climate cool, such as China’s Inner Mongolia or the hydro-abundant Pacific Northwest.
But the mining operation pictured above went next level. They own their own damn power plant:
Investors bought this plant in 2014. It was a fixer-upper. Mothballed power plants lying around for sale tend to be dirty fossil fuel plants.
The Greenidge Generation station in New York had been built in the 1930s as a coal-fired power plant. By 2011, there was not enough demand for its costly, dirty power and it was shut down. After not operating for several years, the new owners switched its fuel to dirty gas and re-started its operations, using the plant’s old pollution permits.
The plant struggled to find demand for its electricity, and the operators turned their attention instead to mining Bitcoin. Pollution started to skyrocket. In just one year, emissions of greenhouse gases increased ten-fold. The plant currently uses 19 MW of power, enough to power 14,500 homes if it weren’t mining Bitcoin. And it has plans to go to 55 MW and the capacity to go to 106 MW. At full capacity, the plant would blow past its current pollution permit — but that permit is up for renewal.
Earthjustice and the Sierra Club have sent a letter to regulators urging them not to allow the company, Greenidge Generation LLC, to expand the air permit and to take notice of the emerging trend of cryptocurrency miners taking over power plants and operating them 24 hours a day, 7 days a week, 365 days a year. At least one other plant in the region is planning to get in on the game, and there are nearly 30 plants in upstate New York alone with the potential to convert to full-time Bitcoin mining. A coal plant in Montana is also ramping back up for cryptocurrency mining.
“The aim of the letter to the New York Department of Conservation is to say this is not some random or isolated thing. Cryptocurrency is real and increasingly important, and dirty power plants are coming back from the dead,” says Earthjustice attorney Mandy DeRoche. “Greenidge just gave other retired, retiring, or peaking plants a roadmap of how to do it, how to recruit investors, how to go public on NASDAQ.”
Earthjustice has spent years fighting in public utility commissions around the country to ensure old, dirty power plants get pushed into retirement — and if replacement power is needed, steer clear of dirty gas in favor of clean energy. Our goal is to hasten the day when everything is powered with 100% clean energy.
New York state has a new climate law, and DeRoche says the commitments made in that law won’t be met if dirty power plants get resurrected and operate 24/7. That should spur legislators and regulators to clarify the regulatory gray zone that miners have exploited here with power generation that’s not sent to the grid.
There are many ways to tackle this issue, and we are exploring them,” says DeRoche. “One solution may be to require renewable generation for cryptocurrency mining, with an excess renewable generation requirement on top, so that the mining is not preventing renewables from going directly into the grid. We need that clean power on the grid as fast as possible to mitigate the unequal and most harmful impacts of climate change.”
The climate crisis is accelerating, and we have less than a decade to dramatically cut our carbon emissions if we hope to preserve a livable planet. Tell your members of Congress it’s time to build a sustainable and just future with the American Jobs Plan.
Australia’s carbon emissions down 20% due to wide take-up of renewable energy
Telegraph UK, 29th July 2021, For Australia’s part, our experience with technology-orientated pathways
gives us confidence that with the right investments and partnerships, a prosperous net-zero world is well within our reach.
On the ground, our real-world rollout of renewables has made clear to Australian firms and families the immense benefits of investing in clean technology. Because of their embrace of our new energy future, Australia’s emissions are down over 20 per cent on 2005 levels and green technology continues to be taken
up at record levels right across our nation.

Japan’s new Basic Energy Plan looks to increased renewable energy. Nuclear power unlikely to go ahead much.
The Ministry of Economy, Trade and Industry (METI) has compiled a draft
revision to Japan’s Basic Energy Plan, which indicates the direction of the
government’s energy policy. The revision brings our attention to the
predicted ratios of various power sources in fiscal 2030.
In order to reduce our dependence on carbon, renewable energy sources were increased
from 22 to 24% three years ago to 36 to 38% in the latest draft revision.
Some view this increase as being insufficient in making renewable energy
Japan’s main energy source.
But we commend the willingness expressed to
undertake the maximum possible implementation of renewable energy as an
utmost priority.
Meanwhile, doubts remain about the percentage of power
generation comprising nuclear reactors. The new Basic Energy Plan is trying
to maintain the 20 to 22% set in the 2015 revisions to the Basic Energy
Plan, but that is unrealistic. To achieve that kind of ratio, Japan would
need to be operating around 27 nuclear reactors at a high rate in fiscal
2030. However, since the major incident at Tokyo Electric Power Co.
Holdings Inc.’s Fukushima Daiichi Nuclear Power Station, only 10 nuclear
reactors have resumed operations. The percentage of power generated by
nuclear reactors in fiscal 2019 was a mere 6%.

By contrast, costs of power generation using renewable energy sources have shown a steady decline. Solar power generation for businesses will produce 1 kilowatt-hour of electricity at estimated costs in the lower 8-yen range to the higher 11-yen range in 2030.
Even though the draft energy supply blueprint calls for reducing Japan’s reliance on nuclear power as much as possible, it nevertheless sets an unrealistic target for the share of nuclear power……..
…..The first order of business for the ministry is to define the composite of power sources in 2050 required to achieve carbon neutrality. Currently, the only imaginable main source of electricity to ensure a greener energy future is renewables.
Clean energy accounted for 21.7 percent of Japan’s total power output last year, close to the target for 2030 (22-24 percent). It would be wiser to make utmost use of the huge potential of renewable energy…………. https://www.asahi.com/ajw/articles/14402202

Greenpeace Rainbow Warrier aims to help workers to transition to renewable energy work
The Greenpeace Rainbow Warrior III ship is in Aberdeen Harbour as part of its Just Transition Tour. The campaign calls on government to train oil and gas workers for a smooth transition to renewable energy schemes. The 190-ft vessel will moor overnight in Aberdeen before heading for Wick with sights set on the 84-turbine Beatrice offshore windfarm sitting lying nine miles off the Caithness coast. The intrepid crew are keen to assess “the challenges and opportunities” facing the platforms’ workers.
Greenpeace UK’s oil campaign leader Mel Evans, head said offshore workers had their full support. He added: They have powered our economy through difficult times and they have plenty of transferable skills which will be vital to our transition to renewable energy. “Politicians must sit down with offshore workers and take urgent action to make the funds, retraining opportunities and jobs available to make Scotland’s clean energy transition a success.”

UK government’s pointless pursuit ofnuclear power, as renewable energy proving to be cheaper and faster.
Renewable energy, mainly wind and solar, is rising on the back of rapidly falling costs. So much so that the International Energy Agency, which has in the past been rather guarded about their potential, has switched over to seeing them as the main way ahead, supplying 90% of global electric power by 2050.
| Dave Elliott: No room for nuclear. As noted in an article in Regional Life, a local conservation e-magazine linked to a local anti nuclear group, the flat landscape of the Dengie peninsula in Essex is punctuated by a line of tall wind turbines, slowly turning and the massive grey-blue hulk of the former Bradwell ‘A’ nuclear power station. These two features it says graphically express the contrast between rise of renewable energy and the demise of nuclear power, the past and the future of electricity generation. Renewable energy, mainly wind and solar, is rising on the back of rapidly falling costs. So much so that the International Energy Agency, which has in the past been rather guarded about their potential, has switched over to seeing them as the main way ahead, supplying 90% of global electric power by 2050. That is actually quite conservative compared to some projections for the UK: renewables are supplying over 43% of UK power at present and the Renewable Energy Association says that reaching 100% is possible by 2032 – indeed Scotland is already almost there. All of which raises thequestion of why we are still pursuing nuclear power- which just about everyone agrees is very much more expensive than wind and solar. The recent BBC TV documentary series on construction work at Hinkley Point C in Somerset made stunningly clear the massive scale and environmental footprint of nuclear projects like this. Especially notable was the vast amount of concrete that had to be poured- the production of which involves significant release of carbon dioxide gas. That is one reason why nuclear plants are not zero carbon options, another being the fact that mining and processing uranium fuel are energy and carbon intensive activities. By contrast, renewable energy systems like solar cells and wind turbines need no fuel to run, and, although energy is needed to make the materials used in their construction, the net carbon/energy lifetime debt is less than for nuclear- one study suggested nuclear produces on average 23 times more emissions than onshore wind per unit electricity generated. The Government’s stated aim is to generate ‘enough electricity from offshore wind to power every home by 2030’. That means many more offshore wind farms, off the East coast and also elsewhere around the UK. With the other renewables also added in and more of them planned (we have 14 GW of solar capacity so far) it is hard to see what the nuclear plants are for – the 9 GW or so of old plants and the new 3.2 GW Hinkley Point C plant, much less any other proposed new ones. The nuclear lobby sometimes argues we need more nuclear to replace nuclear plants that are being closed and also to back up renewables. It is hard to see how that could work, unless the new plants were flexible, and able to compensate for the variable output of the 30GW or so of wind and solar capacity we have at present. As yet there are no plans to run the Hinkley Point C plant that way, or for that matter, the proposed 3.2 GW Sizewell C. In which case, adding more nuclear will mean that, at times of low demand, some cheap renewable output, or some low cost flexible gas plant output, would have to be curtailed. What a waste! All of this to keep the £22bn Hinkley Point, and any that follow, financially viable. Renew Extra 17th July 2021 https://renewextraweekly.blogspot.com/2021/07/no-room-for-nuclear.html |
Japan’s government acknowledges that solar power will be cheaper than nuclear
Solar power eclipses nuclear energy in terms of costs, Asahi Shimbun, By SATOSHI SHINDEN/ Staff Writer, July 13, 2021 For businesses looking ahead to reduce costs, solar power would definitely seem to be the way to go. Households could possibly benefit as well.
A new estimate by the industry ministry on future costs of power generation found that solar power will eclipse nuclear energy in terms of costs as of 2030.
The finding, released July 12, is expected to have significant implications for the nation’s energy policy.
This is the first time for the Ministry of Economy, Trade and Industry to acknowledge that the cost to generate solar power will be lower than that for nuclear power.
The estimates were presented at a meeting of a working group of the Advisory Committee for Natural Resources and Energy the same day.
Estimated costs for nuclear power came to close to the 12 yen level or more per kilowatt-hour as of 2030, about 1 yen higher than the previous estimate in 2015.
Costs for solar power ranged from the lower 8 yen level to close to 12 yen for businesses. The rate for homes was estimated at between the last half of the 9 yen level to the first half of the 14 yen level.
The government and electric utilities have continued to champion nuclear power generation even after the 2011 triple meltdown at the Fukushima No. 1 nuclear plant, citing cost efficiency over other energy sources.
However, the latest estimates would seem to call the legitimacy of that argument into question and will likely have an impact on the government’s Basic Energy Plan, for which officials are working to revise.
The Basic Energy Plan is updated almost every three years.
“The industry ministry has finally acknowledged it can no longer maintain the position that nuclear power is the most economical source of energy,” noted Kenichi Oshima, a professor of environmental economics at Ryukoku University who studies the nation’s nuclear policy, referring to the latest findings about costs.
The estimated costs for generating electricity with nuclear energy have risen each time calculations were made.
The ministry was forced to include ballooning costs for decommissioning of nuclear reactors and decontaminating crippled facilities in the aftermath of the Fukushima nuclear disaster…..
solar energy is getting cheaper.
The latest estimate for solar power was down from the previous calculation in 2015 because the costs of installing solar panels are dropping.
Charges for generating electricity are calculated as follows: the total cost of building a new power facility, operating it for decades and finally dismantling it divided by the overall amount of power produced during the period…… https://www.asahi.com/ajw/articles/14394069
Rapid growth of renewable energy: it’s the major energy source in Europe
Renewable energy capacity around the world grew by a record amount during 2020, even as China continued to build new fossil-fuel burning coal plants. Capacity of wind and solar power grew by 238GW globally – about 50pc larger
than any previous expansion, according to the latest annual review of world energy by oil and gas giant BP.
The jump in renewable output amounts to about seven times the total installed capacity in the UK, and came in a
year marked by a slump in energy use as the pandemic triggered a slowdown in global travel. The share of renewable power, including wind and solar, in the global power mix also rose from 10.3pc to 11.7pc. In Europe, that share reached 23.8pc, making it the first region where renewables are the main source of fuel, BP said.

Even this conservative journal recognises renewables as the only meaningful future energy source – nuclear is irrelevant
Regardless of what the nuclear industry itself wants, the signs are that renewables may be defining themselves not only as the cheapest, but also as the only meaningful energy proposal for the future.
Let’s Leave Nuclear Power In The Past https://www.forbes.com/sites/enriquedans/2021/06/30/lets-leave-nuclear-power-in-thepast/?sh=4beadbb23864 Enrique Dans, Senior Contributor
It makes a lot of sense to start this article by linking to the old smiling sun badge that symbolizes the opposition to nuclear energy, to talk about the increasingly negative perceptions of nuclear power around the world, to the point where, with the exception of a few unconditional enthusiasts, it is beginning to be seen as a technology with less and less of a role in the world’s energy future.
During the 1950s, the term atomic age was widely used to describe a future where all energy would be based on nuclear fission, one in which energy would be so cheap and inexhaustible that it wouldn’t be worth metering it, to the point that it would be used not only to make weapons or provide energy, but even to power cars like the Ford Nucleon, to heat water in swimming pools, to keep artificial hearts beating and even for the mechanism of a ballpoint pen.
What happened? First, the obvious problem of safety: in a world with an increasingly unstable climate and more extreme weather phenomena, nuclear power plants are, as the tenth anniversary of the Fukushima accident on March 11 reminded us, a reckless option. Germany became the first major economy to commit to retiring its nuclear power plants by 2022, but China also seems to be losing interest in the technology due to cost and safety concerns, while nuclear power is relegated to a token role in the US energy map.
Large reactors cannot compete with low renewable energy prices. Many of them have already closed, and furthermore, due to their high cost, complexity and difficulties, it seems very unlikely that any new large plants will be built in the coming decades. Nuclear power has turned out to be a promise that never materializes, and looks increasingly remote as an answer to the climate emergency.
Some point to small modular reactors (SMRs) as the only option that could be implemented on a significant scale in the climate-critical period of the next few decades, but quite a few analyses suggest this is extremely unlikely to happen.
The option that seemed the most obvious can easily be sidelined as new technologies develop and undergo their own economies of scale. Nuclear power, which still generates around 10% of the world’s total energy, is now seen as too slow, too expensive and too dangerous, something no one wants to see being built near their home or town. Regardless of what the nuclear industry itself wants, the signs are that renewables may be defining themselves not only as the cheapest, but also as the only meaningful energy proposal for the future.
Germany’s success in phasing out nuclear energy, and remarkable uptake of solar.
Germany’s nuclear phase out expected to be complete by 2022 as country
cuts capacity by over 60% last decade, says GlobalData. Between 2010 and
2020, installed nuclear capacity in Germany declined from 20.5GW to 8.1GW,
according to GlobalData, which estimates the country will reach 4.1GW by
the end of this year.
The leading data and analytics company notes that
this progression sets Germany on track to completely phase out nuclear by
2022. Rohit Ravetkar, Power Analyst at GlobalData says: “The German
Government has made steady progress towards the elimination of nuclear
power following the Fukushima nuclear disaster in Japan.
Under the Energiewende policy, the country’s aim to fill its power generation void
with renewable power includes a planned increase of solar PV capacity to
100GW by 2030.
The expansion of solar PV systems has been the most
successful in Germany, increasing at an impressive compound annual growth
rate (CAGR) of 11.6% between 2010 and 2020.” Germany has been at the
forefront in the adoption of solar PV technology since 2000. The country
launched the 100,000 rooftop PV program way back in 1999, providing a
significant push to the solar PV technology.

New UK energy report – need for investment in wind and solar, no need for new nuclear.
The UK should grow its solar capacity to 210GW by 2050, unlocking a low
cost transition to net zero, a new report has found. Wind and solar will
need increased investment to grow to generate 98% of the electricity mix,
up from 27% in 2020, according to the report, published by energy provider
Good Energy with modelling from the Energy Systems Catapult (ESC).
Solar Power Portal 22nd June 2021
This will require over 200GW of solar, as well as 150GW of wind and 100GW of
lithium-ion battery energy storage, the Renewable Nation: Pathways to a
Zero Carbon Britain report has said. A substantial amount of that growth is
possible by the end of this decade, with 100GW of solar and 70GW of wind
needed to produce 84% of the country’s electricity by 2030.
The report – which is the first to use the ESC’s Storage and Flexibility model,
which itself combines long-term investment planning with hour-by-hour grid
balancing – found that no new nuclear beyond that under construction
currently was needed for net zero.
Renewable energy consumption grew in 2020 as fossil fuels and nuclear shrank.
Sunrise brief: Renewable energy consumption grew in 2020 as fossil fuels and nuclear shrank, PV Magazine , 17 June 21,
Also on the rise: Black & Veatch unit sets financing for 137 MW Texas project, Rockefeller Foundation partners to fund distributed renewable projects in Africa, and DroneBase closes a funding round as it expands its solar presence.JUNE 16, 2021 DAVID WAGMAN Consumption of renewable energy grew for the fifth year in a row in 2020, reaching a record high of 11.6 quadrillion British thermal units (Btu), or 12% of total U.S. energy consumption.
The Energy Information Administration (EIA) reported the data and said that renewable energy was the only source that increased in 2020 from 2019; fossil fuel and nuclear consumption declined.
Hydroelectric power accounted for about 22% of U.S. renewable energy consumption. Consumption has remained relatively flat since the 1970s, but fluctuates with seasonal rainfall and drought conditions.
Financing set for Texas solar project
Black & Veatch unit Diode Ventures said it reached financial close on the Grizzly Ridge Solar Project, a 137.7 MW solar project located in Hamilton County, Texas, southwest of Fort Worth. The project was co-developed with RKB Energy. Details of the financing were not disclosed.
Once complete, Grizzly Ridge will provide energy to the ERCOT North Zone, a growing economy and power market where there is high demand for all forms of electricity.
The project has an executed interconnection agreement with Brazos Electric Cooperative, the transmission service provider. The area will undergo an upgrade from 69 kV to 138 kV. Diode also is in discussions to add an on-site battery energy storage system to the project.
Rockefeller Foundation partners to bolster renewables
The International Finance Corp., the private sector arm of the World Bank Group, and The Rockefeller Foundation announced a partnership to deploy $150 million of capital in blended finance to leverage up to $2 billion of private sector investment in distributed renewable energy.
The two will prioritize countries in Sub-Saharan Africa and other regions, where both organizations have identified immediate opportunities.
By blending philanthropic and private investment funding, the Rockefeller Foundation and IFC hope to de-risk capital investment in distributed renewable projects in emerging markets and help to address global energy access needs.
An initial “rapid deployment” phase will distribute $30 million in blended concessional finance and grant capital to leverage an active pipeline of distributed renewable energy projects developed by IFC. The funding will go toward IFC’s prototype scaling mini-grid program in addition to distributed renewable energy generation, battery energy storage, and other clean energy technologies to facilitate access………. https://pv-magazine-usa.com/2021/06/16/sunrise-brief-renewable-energy-consumption-grew-in-2020-as-fossil-fuels-and-nuclear-shrank/
We don’t need costly, slow, nuclear power: solar, wind, tidal and wave power can amply do the job
WHEN I visited Orkney in the 1970s, it was deeply involved in the North
Sea Oil boom. The Flotta oil terminal is still operating but renewable
energy – mainly wind and some tidal – generates up to 120 percent of the
electricity needed by Orkney’s 22,000 inhabitants.
The European Marine Energy Centre based in Stromness is trialling 48 tidal and wave power
projects. These include the world’s most powerful tidal turbine, Orbital
Marine Power’s O2 which from the air looks like a giant 250ft long rowing
boat off the isle of Eday. Its 2MW capacity means it could generate enough
clean, predictable electricity to meet the demand of around 2,000 UK homes
and offset approximately 2,200 tonnes of CO2 production per year.
It is just one of countless schemes around the world testing the potential of
renewables other than wind and solar to power the world and save it from
climate change. At an earlier stage of development and planned for near
Liverpool is the £3billion TPGen24, the brainchild of engineer Stuart
Murphy. Its promotional video says: “There is more than enough energy in
the UK’s tidal waters to satisfy the entire needs of the country, if only
it could be captured.
Does Britain need nuclear power to turn us green?
Yes, says Professor Ian Fells, Technical Director of Penultimate Power UK
Ltd which builds compact nuclear High Temperature Gas-cooled Reactor Energy
Hubs.
NO Says Dale Vince Eco-entrepreneur Energy independence from clean,
green renewables is a prize well worth having – and perfectly feasible. We
have enough wind and sun to power this country many times over. Throw in
other sources, such as geothermal – heat from deep under the ground – and
marine power and there should be no need for the UK to waste £50billion a
year and rising on importing oil and gas.
Nuclear has many problems. It is hugely expensive. Nuclear power stations take 10 years to design, 10 years
to build and another 10 years to pay back their carbon debt. We don’t
have time. And at three times the cost of renewables, we don’t need to
pay for that. We can power the grid entirely from renewable energy, at a
fraction of the price in a fraction of the time and have real carbon
reductions almost straight away.
