More Managers Charged For Price Fixing At Ukraine Power Producer

Bitcoin energy consumption is driven by mining electricity demand, with TWh-scale power use, carbon footprint concerns, and Cambridge estimates. Rising prices incentivize more hardware; efficiency gains and renewables adoption shape sustainability outcomes.

Key Points

Bitcoin energy consumption is mining's electricity use, driven by price, device efficiency, and energy mix.

✅ Cambridge tool estimates ~121 TWh annual usage

✅ Rising BTC price incentivizes more mining hardware

✅ Efficiency, renewables, and costs shape footprint

"Mining" for the cryptocurrency is power-hungry, with power curtailments reported during heat waves, involving heavy computer calculations to verify transactions.

Cambridge researchers say it consumes around 121.36 terawatt-hours (TWh) a year - and is unlikely to fall unless the value of the currency slumps, even as Americans use less electricity overall.

Critics say electric-car firm Tesla's decision to invest heavily in Bitcoin undermines its environmental image.

The currency's value hit a record $48,000 (£34,820) this week. following Tesla's announcement that it had bought about $1.5bn bitcoin and planned to accept it as payment in future.

But the rising price offers even more incentive to Bitcoin miners to run more and more machines.

And as the price increases, so does the energy consumption, according to Michel Rauchs, researcher at The Cambridge Centre for Alternative Finance, who co-created the online tool that generates these estimates.

“It is really by design that Bitcoin consumes that much electricity,” Mr Rauchs told BBC’s Tech Tent podcast. “This is not something that will change in the future unless the Bitcoin price is going to significantly go down."

The online tool has ranked Bitcoin’s electricity consumption above Argentina (121 TWh), the Netherlands (108.8 TWh) and the United Arab Emirates (113.20 TWh) - and it is gradually creeping up on Norway (122.20 TWh).

The energy it uses could power all kettles used in the UK, where low-carbon generation stalled in 2019, for 27 years, it said.

However, it also suggests the amount of electricity consumed every year by always-on but inactive home devices in the US alone could power the entire Bitcoin network for a year, and in Canada, B.C. power imports have helped meet demand.

Mining Bitcoin
In order to "mine" Bitcoin, computers - often specialised ones - are connected to the cryptocurrency network.

They have the job of verifying transactions made by people who send or receive Bitcoin.

This process involves solving puzzles, which, while not integral to verifying movements of the currency, provide a hurdle to ensure no-one fraudulently edits the global record of all transactions.

As a reward, miners occasionally receive small amounts of Bitcoin in what is often likened to a lottery.

To increase profits, people often connect large numbers of miners to the network - even entire warehouses full of them, as seen with a Medicine Hat bitcoin operation backed by an electricity deal.

That uses lots of electricity because the computers are more or less constantly working to complete the puzzles, prompting some utilities to consider pauses on new crypto loads in certain regions.

The University of Cambridge tool models the economic lifetime of the world's Bitcoin miners and assumes that all the Bitcoin mining machines worldwide are working with various efficiencies.

Using an average electricity price per kilowatt hour ($0.05) and the energy demands of the Bitcoin network, it is then possible to estimate how much electricity is being consumed at any one time, though in places like China's power sector data can be opaque.

Maritime Electric Hurricane Irma Response details utility crews aiding Turks and Caicos with power restoration, storm recovery, debris removal, and essential services, coordinated with Fortis Inc., despite limited equipment, heat, and over 1,000 downed poles.

Key Points

A utility mission restoring power and essential services in Turks and Caicos after Irma, led by Maritime Electric.

✅ Over 1,000 poles down; crews climbing without bucket trucks

✅ Restoring hospitals, water, and communications first

✅ Fortis Inc. coordination; 2-3 week deployment with follow-on crews

Maritime Electric has sent a crew to help in the clean up and power restoration of Turks and Caicos after the Caribbean island was hit by Hurricane Irma, a storm that also saw FPL's massive response across Florida.

They arrived earlier this week and are working on removing debris and equipment so when supplies arrive, power can be brought back online, and similar mutual aid deployments, including Canadian crews to Florida, have been underway as well.

Fortis Inc., the parent company for Maritime Electric operates a utility in Turks and Caicos.

Kim Griffin, spokesperson for Maritime Electric, said there are over 1000 poles that were brought down by the storm, mirroring Florida restoration timelines reported elsewhere.

"It's really an intense storm recovery," she said. 'Good spirits'

The crew is working with less heavy equipment than they are used to, climbing poles instead of using bucket trucks, in hot and humid weather.

Griffin said their focus is getting essential services restored as quckly as possible, similar to progress in Puerto Rico's restoration efforts following recent hurricanes.

The crew will be there for two or three weeks and Griffin said Maritime Electric may send another group, as seen with Ontario's deployment to Florida, to continue the job.

She said the team has been well received and is in "good spirits."

"The people around them have been very positive that they're there," she said.

"They've said it's just been overwhelming how kind and generous the people have been to them."

Alberta Electricity Rate Cap stays despite carbon tax repeal, keeping the Regulated Rate Option at 6.8 cents/kWh. Levy funds cover market gaps as the UCP reviews NDP policies to maintain affordable utility bills.

Key Points

Program capping RRO power at 6.8 cents/kWh, using levy funds to offset market prices while the UCP reviews policy.

✅ RRO cap fixed at 6.8 cents/kWh for eligible customers

✅ Levy funds pay generators when market prices exceed the cap

✅ UCP reviewing NDP policies to ensure affordable rates

Alberta's carbon tax has been cancelled, but a consumer price cap on electricity — which the levy pays for — is staying in place for now.

June electricity rates are due out on Monday, about four days after the new UCP government did away with the carbon charge on natural gas and vehicle fuel.

Part of the levy's revenue was earmarked by the previous NDP government to keep power prices at or below 6.8 cents per kilowatt hour under new electricity rules set by the province.

"The Regulated Rate Option cap of 6.8 cents/kWh was implemented by the previous government and currently remains in effect. We are reviewing all policies put in place by the former government and will make decisions that ensure more affordable electricity rates for job-creators and Albertans," said a spokesperson for Alberta's energy ministry in an emailed statement.

Albertans with regulated rate contracts and all City of Medicine Hat utility customers only pay that amount or less, though some Alberta ratepayers have faced deferral-related arrears.

If the actual market price rises above that, the difference is paid to generators directly from levy funds, a buffer that matters as experts warn prices are set to soar later this year.

The government has paid more than $55 million to utilities over the past year ending in March 2019, due to that electricity price cap being in place.

Alberta Energy says the price gap program will continue, at least for the time being, amid electricity policy changes being considered.

Hydro-Québec Northeast Clean Energy Transmission delivers surplus hydropower via HVDC interconnections to New York and New England, leveraging long-term contracts and projects like CHPE and NECEC to support carbon-free goals, GHG cuts, and grid reliability.

Key Points

An initiative to expand HVDC links for Quebec hydropower exports, aiding New York and New England decarbonization.

✅ 37,000 MW hydro capacity enables firm, low-carbon exports

✅ Targets NY and NE via CHPE, NECEC, and upgraded interfaces

✅ Backed by long-term PPAs to reduce merchant transmission risk

With roughly 37,000 MW of installed hydro power capacity, Quebec has ample spare capacity that it would like to deliver into Northeastern US markets where ambitious clean energy goals have been announced, but expanding transmission infrastructure is challenging.

Register Now New York recently announced a goal of receiving 100% carbon-free energy by 2040 and the New England states all have ambitious greenhouse gas reduction goals, including a Massachusetts law requiring GHG emissions be 80% below 1990 levels by 2050.

The province-owned company, Hydro Quebec, supplies power to the provinces of Quebec, Ontario and New Brunswick in particular, as well as sending electricity directly into New York and New England. The power transmission interconnections between New York and New England have reached capacity and in order to increase export volumes into the US, "we need to build more transmission infrastructure," Gary Sutherland, relationship manager in business development, recently said during a presentation to reporters in Montreal.

TRANSMISSION OPTIONS

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, as the province has closed the door on nuclear power and continues to prioritize hydropower, Sutherland said.

The company is looking to sign long-term power supply contracts that could help alleviate some of the investment risk associated with these large infrastructure projects.

"It`s interesting to recall that in the 1980s, two decade-long contracts paved the way for construction of Phase II of the multi-terminal direct-current system (MTDCS), a cross-border line that delivers up to 2,000 MW from northern Quebec to New England," Hydro Quebec spokeswoman Lynn St-Laurent said in an email.

Long-term prices have been persistently low since 2012, following the shale gas boom and the economic decline in 2008-2009, St-Laurent said. "As such, investment risks are too high for merchant transmission projects," she said.

Northeast power market fundamentals "remain strong for long-term contracts," on transmission projects or equipment upgrades that can deliver clean power from Quebec and "help our neighbors reach their ambitious clean energy goals," St-Laurent said.

NEW ENGLAND

In March 2017 an HQ proposal was selected by Massachusetts regulators to supply 9.45 TWh of firm energy to be delivered for 20 years. HQ`s proposal consisted of hydro power supply and possible transmission scenarios developed in conjunction with US partners.

The two leading options include a route through New Hampshire called Northern Pass and New England Clean Energy Connect through Maine.

The New Hampshire Site Evaluation Committee in March 2018 voted unanimously to deny approval of the $1.6 billion Northern Pass Transmission project, which is a joint venture between HQ and Eversource Energy`s transmission business. Eversource has been fighting the decision, with the New Hampshire Supreme Court accepting the company`s appeal of the NHSEC decision in October.

Briefs are being filed and oral arguments are likely to begin late spring or early summer, spokesman William Hinkle said in an email Tuesday.

After the Northern Pass permitting delay, Massachusetts chose the New England Clean Energy Connect project, which is a projected 1,200 MW transmission line, with 1,090 MW contracted to Massachusetts, leaving 110 MW for use on a merchant basis, according to St-Laurent.

NECEC is a joint venture between HQ and Central Maine Power, which is a subsidiary of Avangrid, a company affiliated with Spain`s Iberdrola. The NECEC project has received opposition from some environmental groups and still needs several state and federal permits.

NEW YORK

"The 5% of New York`s load that we furnish year in and year out ... is mostly going into the north of the state, it`s not coming down here," Sutherland said during a discussion at Pace University in New York City in 2017.

One potential project moving through the permitting phase, is the $2.2 billion, 1,000-MW Champlain Hudson Power Express transmission line being pursued by Transmission Developers -- a Blackstone portfolio company -- that would transport power from Quebec to Queens, New York.

Under New York`s proposed Climate Leadership Act which calls for the 100% carbon-free energy goal, renewable generation eligibility would be determined by the Public Service Commission. The PSC did not respond to a question about whether hydro power from Quebec is being considered as a potential option for meeting the state`s clean energy goal.

Germany 2030 Electricity Demand Forecast projects 658 TWh, driven by e-mobility, heat pumps, and green hydrogen. BMWi and BDEW see higher renewables, onshore wind, photovoltaics, and faster grid expansion to meet climate targets.

Key Points

A BMWi outlook to 658 TWh by 2030, led by e-mobility, plus demand from heat pumps, green hydrogen, and industry.

✅ Transport adds ~70 TWh; cars take 44 TWh by 2030

✅ Heat pumps add 35 TWh; green hydrogen needs ~20 TWh

✅ BDEW urges 70% renewables and faster grid expansion

Gross electricity consumption in Germany will increase from 595 terawatt hours (TWh) in 2018 to 658 TWh in 2030. That is an increase of eleven percent. This emerges from the detailed analysis of the development of electricity demand that the Federal Ministry of Economics (BMWi) published on Tuesday. The main driver of the increase is therefore the transport sector. According to the paper, increased electric mobility in particular contributes 68 TWh to the increase, in line with rising EV power demand trends across markets. Around 44 TWh of this should be for cars, 7 TWh for light commercial vehicles and 17 TWh for heavy trucks. If the electricity consumption for buses and two-wheelers is added, this results in electricity consumption for e-mobility of around 70 TWh.

The number of purely battery-powered vehicles is increasing according to the investigation by the BMWi to 16 million by 2030, reflecting the global electric car market momentum, plus 2.2 million plug-in hybrids. In 2018 there were only around 100,000 electric cars, the associated electricity consumption was an estimated 0.3 TWh, and plug-in mileage in 2021 highlighted the rapid uptake elsewhere. For heat pumps, the researchers predict an increase in demand by 35 TWh to around 42 TWh. They estimate the electricity consumption for the production of around 12.5 TWh of green hydrogen in 2030 to be just under 20 TWh. The demand at battery factories and data centers will increase by 13 TWh compared to 2018 by this point in time. In the data centers, there is no higher consumption due to more efficient hardware despite advancing digitization.

The updated figures are based on ongoing scenario calculations by Prognos, in which the market researchers took into account the goals of the Climate Protection Act for 2030 and the wider European electrification push for decarbonization. In the preliminary estimate presented by Federal Economics Minister Peter Altmaier (CDU) in July, a range of 645 to 665 TWh was determined for gross electricity consumption in 2030. Previously, Altmaier officially said that electricity demand in this country would remain constant for the next ten years. In June, Chancellor Angela Merkel (CDU) called for an expanded forecast that would have to include trends in e-mobility adoption within a decade and the Internet of Things, for example.

Higher electricity demand
The Federal Association of Energy and Water Management (BDEW) is assuming an even higher electricity demand of around 700 TWh in nine years. In any case, a higher share of renewable energies in electricity generation of 70 percent by 2030 is necessary in order to be able to achieve the climate targets and to address electricity price volatility risks. The expansion paths urgently need to be increased and obstacles removed. This could mean around 100 gigawatts (GW) for onshore wind turbines, 11 GW for biomass and at least 150 GW for photovoltaics by 2030. Faster network expansion and renovation will also become even more urgent, as electric cars challenge grids in many regions.

UK Renewables Surpass Nuclear Milestone as wind farms and solar panels outpace atomic output, cutting greenhouse gas emissions. BEIS data show low-carbon power generation rising while onshore wind subsidies and auction timelines face policy debate.

Key Points

It is the quarter when UK wind and solar generated more electricity than nuclear, signaling cleaner, low-carbon growth.

✅ BEIS reports wind and solar at 18.33 TWh vs nuclear 16.69 TWh

✅ Energy sector emissions fell 8% as coal use dropped

✅ Calls grow to reopen onshore wind support via CFD auctions

Wind farms and solar panels, with wind leading the power mix during key periods, produced more electricity than the UK’s eight nuclear power stations for the first time at the end of last year, official figures show.

Britain’s greenhouse gas emissions also continued to fall, dropping 3% in 2017, as coal use fell and the use of renewables climbed, though low-carbon generation stalled in 2019 according to later data.

Energy experienced the biggest drop in emissions of any UK sector, of 8%, while pollution from transport and businesses stayed flat.

Energy industry chiefs said the figures showed that the government should rethink its ban on onshore wind subsidies, a move that ministers have hinted could happen soon.

Lawrence Slade, chief executive of the big six lobby group Energy UK, said: “We need to keep up the pace ... by ensuring that the lowest cost renewables are no longer excluded from the market.”

Across the whole year, low-carbon sources of power – wind, solar, biomass and nuclear – provided a record 50.4% of electricity, up from 45.7% in 2016, when wind beat coal for the first time.

But in the fourth quarter of 2017, high wind speeds, new renewables installations and lower nuclear output saw wind and solar becoming the second biggest source of power for the first time.

Wind and solar generated 18.33 terawatt hours (TWh), with nuclear on 16.69TWh, and the UK later set a new record for wind power during 2019, the figures published by the Department for Business, Energy and Industrial Strategy show.

But renewables still have a long way to go to catch up with gas, the UK’s top source of electricity at 36.12TWh, which saw its share of generation fall slightly, though at times wind became the main source as capacity expanded.

Greenpeace said the figures showed the government should capitalise on its lead in renewables and “stop wasting time and money propping up nuclear power”.

Horizon Nuclear Power, a subsidiary of the Japanese conglomerate Hitachi, is in talks with Whitehall officials for a financial support package from the government, which it says it needs by midsummer.

By contrast, large-scale solar and onshore wind projects are not eligible for support, after the Conservative government cut subsidies in 2015.

However the energy minister, Claire Perry, recently told House Magazine that “we will have another auction that brings forward wind and solar, we just haven’t yet said when”.
