State cuts Duke's expansion plans in half at Cliffside facility

Bitcoin Energy Consumption drives debate on blockchain mining, proof-of-work, carbon footprint, and emissions, with CCAF estimates in terawatt hours highlighting electricity demand, fossil fuel reliance, and sustainability concerns for data centers and cryptocurrency networks.

Key Points

Electricity used by Bitcoin proof-of-work mining, often fossil-fueled, estimated by CCAF in terawatt hours.

✅ CCAF: 40-445 TWh, central estimate ~130 TWh

✅ ~66% of mining electricity sourced from fossil fuels

✅ Proof-of-work increases hash rate, energy, and emissions

The University of Cambridge Centre for Alternative Finance (CCAF) studies the burgeoning business of cryptocurrencies.

It calculates that Bitcoin's total energy consumption is somewhere between 40 and 445 annualised terawatt hours (TWh), with a central estimate of about 130 terawatt hours.

The UK's electricity consumption is a little over 300 TWh a year, while Argentina uses around the same amount of power as the CCAF's best guess for Bitcoin, as countries like New Zealand's electricity future are debated to balance demand.

And the electricity the Bitcoin miners use overwhelmingly comes from polluting sources, with the U.S. grid not 100% renewable underscoring broader energy mix challenges worldwide.

The CCAF team surveys the people who manage the Bitcoin network around the world on their energy use and found that about two-thirds of it is from fossil fuels, and some regions are weighing curbs like Russia's proposed mining ban amid electricity deficits.

Huge computing power - and therefore energy use - is built into the way the blockchain technology that underpins the cryptocurrency has been designed.

It relies on a vast decentralised network of computers.

These are the so-called Bitcoin "miners" who enable new Bitcoins to be created, but also independently verify and record every transaction made in the currency.

In fact, the Bitcoins are the reward miners get for maintaining this record accurately.

It works like a lottery that runs every 10 minutes, explains Gina Pieters, an economics professor at the University of Chicago and a research fellow with the CCAF team.

Data processing centres around the world, including hotspots such as Iceland's mining strain, race to compile and submit this record of transactions in a way that is acceptable to the system.

They also have to guess a random number.

The first to submit the record and the correct number wins the prize - this becomes the next block in the blockchain.

Estimates for bitcoin's electricity consumption
At the moment, they are rewarded with six-and-a-quarter Bitcoins, valued at about $50,000 each.

As soon as one lottery is over, a new number is generated, and the whole process starts again.

The higher the price, says Prof Pieters, the more miners want to get into the game, and utilities like BC Hydro suspending new crypto connections highlight grid pressures.

"They want to get that revenue," she tells me, "and that's what's going to encourage them to introduce more and more powerful machines in order to guess this random number, and therefore you will see an increase in energy consumption," she says.

And there is another factor that drives Bitcoin's increasing energy consumption.

The software ensures it always takes 10 minutes for the puzzle to be solved, so if the number of miners is increasing, the puzzle gets harder and the more computing power needs to be thrown at it.

Bitcoin is therefore actually designed to encourage increased computing effort.

The idea is that the more computers that compete to maintain the blockchain, the safer it becomes, because anyone who might want to try and undermine the currency must control and operate at least as much computing power as the rest of the miners put together.

What this means is that, as Bitcoin gets more valuable, the computing effort expended on creating and maintaining it - and therefore the energy consumed - inevitably increases.

We can track how much effort miners are making to create the currency.

They are currently reckoned to be making 160 quintillion calculations every second - that's 160,000,000,000,000,000,000, in case you were wondering.

And this vast computational effort is the cryptocurrency's Achilles heel, says Alex de Vries, the founder of the Digiconomist website and an expert on Bitcoin.

All the millions of trillions of calculations it takes to keep the system running aren't really doing any useful work.

"They're computations that serve no other purpose," says de Vries, "they're just immediately discarded again. Right now we're using a whole lot of energy to produce those calculations, but also the majority of that is sourced from fossil energy, and clean energy's 'dirty secret' complicates substitution."

The vast effort it requires also makes Bitcoin inherently difficult to scale, he argues.

"If Bitcoin were to be adopted as a global reserve currency," he speculates, "the Bitcoin price will probably be in the millions, and those miners will have more money than the entire [US] Federal budget to spend on electricity."

"We'd have to double our global energy production," he says with a laugh, even as some argue cheap abundant electricity is getting closer to reality today. "For Bitcoin."

He says it also limits the number of transactions the system can process to about five per second.

This doesn't make for a useful currency, he argues.

And that view is echoed by many eminent figures in finance and economics.

The two essential features of a successful currency are that it is an effective form of exchange and a stable store of value, says Ken Rogoff, a professor of economics at Harvard University in Cambridge, Massachusetts, and a former chief economist at the International Monetary Fund (IMF).

He says Bitcoin is neither.

"The fact is, it's not really used much in the legal economy now. Yes, one rich person sells it to another, but that's not a final use. And without that it really doesn't have a long-term future."

What he is saying is that Bitcoin exists almost exclusively as a vehicle for speculation.

So, I want to know: is the bubble about to burst?

"That's my guess," says Prof Rogoff and pauses.

"But I really couldn't tell you when."

Trump Offshore Wind Pledge signals a push for deregulation over renewable energy, challenging climate policy, green jobs, and coastal development while citing marine ecosystems, navigation, and energy independence amid state-federal permitting and legal hurdles.

Key Points

Trump's vow to cancel offshore wind projects favors deregulation and fossil fuels, impacting climate policy and jobs.

✅ Day-one plan to scrap offshore wind leases and permits

✅ Risks to renewable targets, grid mix, and coastal supply chains

✅ Likely court fights and state-federal regulatory conflicts

During his tenure as President of the United States, Donald Trump made numerous promises and policy proposals, many of which sparked controversy and debate. One such pledge was his vow to scrap offshore wind projects on "day one" of his presidency. This bold statement, while appealing to certain interests, raised concerns about its potential impact on U.S. offshore wind growth and environmental conservation efforts.

Trump's opposition to offshore wind projects stemmed from various factors, including his skepticism towards renewable energy, even as forecasts point to a $1 trillion offshore wind market in coming years, concerns about aesthetics and property values, and his focus on promoting traditional energy sources like coal and oil. Throughout his presidency, Trump prioritized deregulation and sought to roll back environmental policies introduced by previous administrations, arguing that they stifled economic growth and hindered American energy independence.

The prospect of scrapping offshore wind projects drew mixed reactions from different stakeholders. Supporters of Trump's proposal pointed to potential benefits such as preserving scenic coastal landscapes, protecting marine ecosystems, and addressing concerns about navigational safety and national security. Critics, however, raised valid concerns about the implications of such a decision on the renewable energy sector, including progress toward getting 1 GW on the grid nationwide, climate change mitigation efforts, and job creation in the burgeoning green economy.

Offshore wind energy has emerged as a promising source of clean, renewable power with the potential to reduce greenhouse gas emissions and diversify the energy mix. Countries like Denmark, the United Kingdom, and Germany have made significant investments in offshore wind in Europe, demonstrating its viability as a sustainable energy solution. In the United States, offshore wind projects have gained traction in states like Massachusetts, New York, and New Jersey, where coastal conditions are conducive to wind energy generation.

Trump's pledge to scrap offshore wind projects on "day one" of his presidency raised questions about the feasibility and legality of such a move. While the president has authority over certain aspects of energy policy and regulatory oversight, the development of offshore wind projects often involves multiple stakeholders, including state governments, local communities, private developers, and federal agencies, and actions such as Interior's move on Vineyard Wind illustrate federal leverage in permitting. Any attempt to halt or reverse ongoing projects would likely face legal challenges and regulatory hurdles, potentially delaying or derailing implementation.

Moreover, Trump's stance on offshore wind projects reflected broader debates about the future of energy policy, environmental protection, and economic development. While some argued for prioritizing fossil fuel extraction and traditional energy infrastructure, others advocated for a transition towards clean, renewable energy sources, drawing on lessons from the U.K. about wind deployment, to mitigate climate change and promote sustainable development. The Biden administration, which succeeded the Trump presidency, has signaled a shift towards a more climate-conscious agenda, including support for renewable energy initiatives and commitments to rejoin international agreements like the Paris Climate Accord.

In hindsight, Trump's pledge to scrap offshore wind projects on "day one" of his presidency underscores the complexities of energy policy and the importance of balancing competing interests and priorities. While concerns about aesthetics, property values, and environmental impact are valid, addressing the urgent challenge of climate change requires bold action and innovation in the energy sector. Offshore wind energy presents an opportunity, as seen in the country's biggest offshore wind farm approved in New York, to harness the power of nature in a way that is both environmentally responsible and economically beneficial. As the United States navigates its energy future, finding common ground and forging partnerships will be essential to ensure a sustainable and prosperous tomorrow.

PG&E Wildfire Assistance Program offers court-approved aid and emergency grants for Northern California wildfires and Camp Fire victims, covering unmet needs, housing, and essentials; apply online by November 15, 2019 under Chapter 11-funded eligibility.

Key Points

A $105M, court-approved aid fund offering unmet-needs payments and emergency support for 2017-2018 wildfire victims.

✅ $5,000 Basic Unmet Needs per household, self-certified

✅ Supplemental aid for extreme circumstances after basic grants

✅ Apply online; deadline November 15, 2019; identity required

Beginning today, August 15, 2019, those displaced by the 2017 Northern California wildfires and 2018 Camp fire can apply for aid through an independently administered Wildfire Assistance Program funded by Pacific Gas and Electric Company (PG&E). PG&E’s $105 million fund, approved by the judge in PG&E’s Chapter 11 cases and related bankruptcy plan, is intended to help those who are either uninsured or need assistance with alternative living expenses or other urgent needs. The court-approved independent administrator is set to file the eligibility criteria as required by the court and will open the application process.

“Our goal is to get the money to those who most need it as quickly as possible. We will prioritize wildfire victims who have urgent needs, including those who are currently without adequate shelter,” said Cathy Yanni, plan administrator. Yanni is partnering with local agencies and community organizations to administer the fund, and PG&E also supports local communities through property tax contributions to counties.

“We appreciate the diligent work of the fund administrator in quickly establishing a way to distribute these funds and ensuring the program supports those with the most immediate needs. PG&E is focused on helping those impacted by the devastating wildfires in recent years and strengthening our energy system to reduce wildfire risks and prevent utility-caused catastrophic fires. We feel strongly that helping these communities now is the right thing to do,” said Bill Johnson, CEO and President of PG&E Corporation.

Applicants can request a “Basic Unmet Needs” payment of $5,000 per household for victims who establish basic eligibility requirements and self-certify that they have at least $5,000 of unmet needs that have not been compensated by the Federal Emergency Management Agency (FEMA). Payments are to support needs such as water, food, prescriptions, medical supplies and equipment, infant formula and diapers, personal hygiene items, and transportation fuels beyond what FEMA covered in the days immediately following the declared disasters, aligning with broader health and safety actions the company has taken.

Those who receive basic payments may also qualify for a “Supplemental Unmet Needs” payment. These funds will be available only after “Basic Unmet Needs” payments have been issued. Supplemental payments will be available to individuals and families who currently face extreme or extraordinary circumstances as compared to others who were impacted by the 2017 and 2018 wildfires, including areas affected by power line-related fires across California.

To qualify for the payments, applicants’ primary residence must have been within the boundary of the 2017 Northern California wildfires or the 2018 Camp fire in Butte County. Applicants also must establish proof of identity and certify that they are not requesting payments for an expense already paid for by FEMA.

Applicants can find more information and apply for assistance at https://www.norcalwildfireassistanceprogram.com/. The deadline to file for aid is November 15, 2019.

The $105 million being provided by PG&E was made available from the company’s cash reserves. PG&E will not seek cost recovery from its customers, and its rates are set to stabilize in 2025 according to recent guidance.

U.S. Energy Dominance envisions deregulation, oil and gas growth, LNG exports, pipelines, and geopolitical leverage, while facing OPEC pricing power, infrastructure bottlenecks, climate policy pressures, and accelerating renewables in global markets.

Key Points

U.S. policy to grow fossil fuel output and exports via deregulation, bolstering energy security, geopolitical influence.

✅ Deregulation to expand drilling, pipelines, and export capacity

✅ Exposed to OPEC pricing, global shocks, and cost competitiveness

✅ Faces infrastructure, ESG finance, and renewables transition risks

Former President Donald Trump has consistently advocated for “energy dominance” as a cornerstone of his energy policy. In his vision, the United States would leverage its abundant natural resources to achieve energy self-sufficiency, flood global markets with cheap energy, and undercut competitors like Russia and OPEC nations. However, while the rhetoric resonates with many Americans, particularly those in energy-producing states, the pursuit of energy dominance faces significant real-world challenges that could limit its feasibility and impact.

The Energy Dominance Vision

Trump’s energy dominance strategy revolves around deregulation, increased domestic production of oil and gas, and the rollback of climate-oriented restrictions. During his presidency, he emphasized opening federal lands to drilling, accelerating the approval of pipelines, and, through an executive order, boosting uranium and nuclear energy initiatives, as well as withdrawing from international agreements like the Paris Climate Accord. The goal was not only to meet domestic energy demands but also to establish the U.S. as a major exporter of fossil fuels, thereby reducing reliance on foreign energy sources.

This approach gained traction during Trump’s first term, with the U.S. achieving record levels of oil and natural gas production. Energy exports surged, making the U.S. a net energy exporter for the first time in decades. Yet, critics argue that this policy prioritizes short-term economic gains over long-term sustainability, while supporters believe it provides a roadmap for energy security and geopolitical leverage.

Market Realities

The energy market is complex, influenced by factors beyond the control of any single administration, with energy crisis impacts often cascading across sectors. While the U.S. has significant reserves of oil and gas, the global market sets prices. Even if the U.S. ramps up production, it cannot insulate itself entirely from price shocks caused by geopolitical instability, OPEC production cuts, or natural disasters.

For instance, despite record production in the late 2010s, American consumers faced volatile gasoline prices during an energy crisis driven by $5 gas and external factors like tensions in the Middle East and fluctuating global demand. Additionally, the cost of production in the U.S. is often higher than in countries with more easily accessible reserves, such as Saudi Arabia. This limits the competitive advantage of U.S. energy producers in global markets.

Infrastructure and Environmental Concerns

A major obstacle to achieving energy dominance is infrastructure. Expanding oil and gas production requires investments in pipelines, export terminals, and refineries. However, these projects often face delays due to regulatory hurdles, legal challenges, and public opposition. High-profile pipeline projects like Keystone XL and Dakota Access have become battlegrounds between industry proponents and environmental activists, and cross-border dynamics such as support for Canadian energy projects amid tariff threats further complicate permitting, highlighting the difficulty of reconciling energy expansion with environmental and community concerns.

Moreover, the transition to cleaner energy sources is accelerating globally, with many countries committing to net-zero emissions targets. This trend could reduce the demand for fossil fuels in the long run, potentially leaving U.S. producers with stranded assets if global markets shift more quickly than anticipated.

Geopolitical Implications

Trump’s energy dominance strategy also hinges on the belief that U.S. energy exports can weaken adversaries like Russia and Iran. While increased American exports of liquefied natural gas (LNG) to Europe have reduced the continent’s reliance on Russian gas, achieving total energy independence for allies is a monumental task. Europe’s energy infrastructure, designed for pipeline imports from Russia, cannot be overhauled overnight to accommodate LNG shipments.

Additionally, the influence of major producers like Saudi Arabia and the OPEC+ alliance remains significant, even as shifts in U.S. policy affect neighbors; in Canada, some viewed Biden as better for the energy sector than alternatives. These countries can adjust production levels to influence prices, sometimes undercutting U.S. efforts to expand its market share.

The Renewable Energy Challenge

The growing focus on renewable energy adds another layer of complexity. Solar, wind, and battery storage technologies are becoming increasingly cost-competitive with fossil fuels. Many U.S. states and private companies are investing heavily in clean energy to align with consumer preferences and global trends, amid arguments that stepping away from fossil fuels can bolster national security. This shift could dampen the domestic demand for oil and gas, challenging the long-term viability of Trump’s energy dominance agenda.

Moreover, international pressure to address climate change could limit the expansion of fossil fuel infrastructure. Financial institutions and investors are increasingly reluctant to fund projects perceived as environmentally harmful, further constraining growth in the sector.

While Trump’s call for U.S. energy dominance taps into a desire for economic growth and energy security, it faces numerous challenges. Global market dynamics, infrastructure bottlenecks, environmental concerns, and the transition to renewable energy all pose significant barriers to achieving the ambitious vision.

For the U.S. to navigate these challenges effectively, a balanced approach that incorporates both traditional energy sources and investments in clean energy is likely needed. Striking this balance will require careful policymaking that considers not just immediate economic gains but also long-term sustainability and global competitiveness.

France Nuclear Heatwave Restrictions signal reduced nuclear power along the Rhone River as EDF imposes output limits due to high water temperatures, grid needs, with minimal price impact amid strong solar and exports.

Key Points

Temporary EDF output limits at Rhone River reactors due to hot water, protecting ecosystems and grid reliability.

✅ EDF expects halved output at Bugey and Saint Alban.

✅ Cuts align with water temperature and discharge rules.

✅ Weekend midday curtailments offset by solar supply.

The high temperature warning has come early this year but will affect fewer nuclear power plants. High temperatures could halve nuclear power production, with river temperature limits at plants along France's Rhone River this week. 

Output restrictions are expected at two nuclear plants in eastern France due to high temperature forecasts, nuclear operator EDF said. It comes several days ahead of a similar warning that was made last year but will affect fewer plants, and follows a period when power demand has held firm during lockdowns across Europe.

The hot weather is likely to halve the available power supply from the 3.6 GW Bugey plant from 13 July and the 2.6 GW Saint Alban plant from 16 July, the operator said.

However, production will be at least 1.8 GW at Bugey and 1.3 GW at Saint Alban to meet grid requirements, and may change according to grid needs, the operator said.

Kpler analyst Emeric de Vigan said the restrictions were likely to have little effect on output in practice. Cuts are likely only at the weekend or midday when solar output was at its peak so the impact on power prices would be slim.

He said the situation would need monitoring in the coming weeks, however, noting it was unusually early in the summer for nuclear-powered France to see such restrictions imposed.

Water temperatures at the Bugey plant already eclipsed the initial threshold for restrictions on 9 July, as European power hits records during the heatwave. They are currently forecast to peak next week and then drop again, Refinitiv data showed.

"France is currently net exporting large amounts of power – and, despite a nuclear power dispute with Germany, single nuclear units' supply restrictions will not have the same effect as last year," Refinitiv analyst Nathalie Gerl said.

The Garonne River in southern France has the highest potential for critical levels of warming, but its Golfech plant is currently offline for maintenance until mid-August, as Europe faces nuclear losses, the data showed.

"(The restrictions were) to be expected and it will probably occur more often," Greenpeace campaigner Roger Spautz said.

"The authorities must stick to existing regulations for water discharges. Otherwise, the ecosystems will be even more affected," he added.

BC Hydro Bitcoin Scam targets small businesses with utility impersonation, call spoofing, and disconnection threats, demanding prepaid cards, cash cards, or bitcoin. Learn payment policies and key warning signs to avoid costly power shutoffs.

Key Points

A phone fraud where impostors threaten power disconnection and demand immediate payment via bitcoin or prepaid cards.

✅ Demands bitcoin, cash cards, or prepaid credit within minutes

✅ Uses caller ID spoofing and utility impersonation tactics

✅ BC Hydro never takes bitcoin or prepaid cards for bills

'I've gotta give him very high marks for being a good scammer,' says almost-fooled business owner

It's an old scam with a new twist.

Fraudsters pretending to be BC Hydro representatives are threatening to disconnect small business owners' power, mirroring Toronto Hydro scam warnings recently, unless they send in cash cards, prepaid credit cards or even bitcoin right away.

Colin Mackintosh, owner of Trans National Art in Langley, B.C., said he almost was fooled by one such scammer.

It was just before quitting time on Thursday at his shop when he got an unpleasant phone call.

"The phone rings. My partner hands me the phone and this fellow says to me that he's outside, he works with BC Hydro and he has a disconnect notice," Mackintosh said.

The caller, Mackintosh said, claimed that if an immediate payment wasn't made they'd cut off the company's power.

'Very well done'

BC Hydro says the scam has been around for a while, and amid commercial power use during COVID-19 in B.C., demanding payment in bitcoin is a new wrinkle.

Fraudsters mostly target small businesses because losing their power for a day or two would be a huge financial hit, a spokesperson said.

Mackintosh said the scammer knew all about the business. His number even showed up as BC Hydro on the call display, and the utility has faced scrutiny in a regulator report unrelated to such scams.

"He had all the answers to every question I seemed to have for him.  Very professional. Very well done. I've gotta give him very high marks for being a good scammer," Mackintosh said.

The caller demanded Mackintosh make an immediate payment at the nearest BC Hydro kiosk. Mackintosh was directed to drive to a certain address to make the payment.

He was ready to pay hundreds of dollars but when he got to the address, there was no kiosk: just a tire shop and inside something that looked like a cash machine but was actually a bitcoin ATM.

"At the very top of it, in little letters, it said 'Bit Coin,'" Mackintosh said. "As soon as I saw those two words, I told him in two expressive words what I thought of him and I hung up the phone."

Scam increasing

BC Hydro spokesperson Mora Scott said fraudsters target small businesses because their livelihoods depend on power, and customers face pressures highlighted in a deferred costs report as well.

"Fraudsters will reach out to our customers pretending to be B.C. Hydro representatives," said Scott.

"They'll demand an immediate payment or they'll disconnect their power. This did start to surface around 2015 but we have seen an increase recently."

Scott said that BC Hydro will never ask for banking information over the phone and does not accept cash card, prepaid credit cards or bitcoin as payment, and customers can consult BC Hydro bill relief for legitimate assistance.
