Wallpaper which emits light could replace traditional light bulbs and cut carbon emissions within a few years.

The technology uses an electrical current to stimulate chemicals to produce light, and a Welsh company developing it has been awarded a grant of £454,000 from the Carbon Trust to help get it into homes and businesses.

The organic light emitting diodes (OLED), which can be coated on to a thin flexible film to cover walls like wallpaper, can also be used for flat screen televisions, computers and mobile phone displays. It needs a very low operating voltage and can be powered by solar panels or batteries, allowing it to be used outdoors to light road signs and barriers without the need for mains electricity.

Ken Lacey, the chief executive of LOMOX Ltd, said the company hoped to make it available to lighting and screen producers by 2012.

Tesla Electric is preparing to expand in the UK

Tesla Electric UK Expansion signals retail energy entry, leveraging Powerwall VPPs for grid services, dynamic pricing, and energy trading, building on Texas success and Octopus Energy ties to buy and sell electricity automatically.

 

Key Points

Tesla's plan to launch Tesla Electric in the UK, using Powerwall VPPs to retail energy, trade power, and hedge peaks.

✅ Retail energy model built on Powerwall VPP aggregation

✅ Automated buy-sell arbitrage with dynamic pricing

✅ Leverages prior UK approval and Octopus Energy ties

 

According to a new job posting, Tesla Electric, Tesla’s new electric utility division, is preparing to expand in the United Kingdom as regions such as California grid planners look to electric vehicles for stability to manage demand.

Late last year, after gaining experience through its virtual power plants (VPPs), including response during California blackouts that pressured the grid, Tesla took things a step further with the launch of “Tesla Electric.”

Instead of reacting to specific “events” and providing services to your local electric utilities through demand response programs, as Tesla Powerwall owners have done in VPPs in California, Tesla Electric is actively and automatically buying and selling electricity for Tesla Powerwall owners – providing a buffer against peak prices.

The company is essentially becoming an energy retailer, aligning with a major future for its energy business envisioned by leadership.

Tesla Electric is currently only available to Powerwall owners in Texas, but the company has plans to expand its products through this new division.

We recently reported on Tesla Electric customers in Texas making as much as $150 a day selling electricity back to the grid through the program.

Now Tesla is looking to expand Tesla Electric to the UK, where grid capacity for rising EV demand remains a key consideration.

The company has listed a new job posting for a role called “Head of Operations, Tesla Electric – Retail Energy.”

This has been in the works for a while now. Tesla used to have a partnership with Octopus Energy in the UK for special electricity rates for its owners, during a period when UK EV inquiries surged amid a fuel supply crisis, but it seemed to be a stepping stone before it would itself become an energy provider in the market.

In 2020, Tesla was officially approved as an electricity retailer in the UK. Now it looks like Tesla is going to use this approval with the launch of Tesla Electric.

Turkish powership to generate electricity from LNG in Senegal

Karpowership LNG powership in Senegal will supply 15% of the grid, a 235 MW floating power plant bound for Dakar, enabling fast deployment, base-load electricity, and cleaner natural gas generation for West Africa.

 

Key Points

A 235 MW floating plant supplying 15% of Senegal's grid with fast, reliable, lower-emission LNG electricity.

✅ 235 MW LNG-ready floating plant meets 15% of Senegal's demand

✅ Rapid deployment: commercial operations expected early October

✅ Cleaner natural gas conversion planned after six months

 

Turkey's Karpowership company, the designer and builder of the world's first floating power plants and the global brand of Karadeniz Holding, will meet 15% of Senegal's electricity needs from liquefied natural gas (LNG) with the 235-megawatt (MW) powership Ayşegül Sultan, which started its voyage from Turkey to Senegal, where an African Development Bank review of a coal plant is underway, on Sunday.

Karpowership, operating 22 floating power plants in more than 10 countries around the world, where France's first offshore wind turbine is now producing electricity, has invested over $5 billion in this area.

In a statement to members of the press at Karmarine Shipyard, Karpowership Trade Group Chair Zeynep Harezi said they aimed to provide affordable electricity to countries in need of electricity quickly and reliably, as projects like the Egypt-Saudi power link expand regional grids, adding that they could commission energy ships capable of generating the base electric charge of the countries, as tidal power in Nova Scotia begins supplying the grid, in a period of about a month.

Harezi recalled that Karpowership commissioned the first floating energy ship in 2007 in Iraq, followed by Lebanon, Ghana, Indonesia, Mozambique, Zambia, Gambia, Sierra Leone, Sudan, Cuba, Guinea Bissau and Senegal, while Scottish tidal power demonstrates marine potential as well. "We meet the electricity needs of 34 million people in many countries," she stressed. Harezi stated that the energy ships, all designed and produced by Turkish engineers, use liquid fuel, but all ships can covert to the second fuel.

Considering the impact of electricity production on the environment, Harezi noted that they plan to convert the entire fleet from liquid fuel to natural gas, with complementary approaches like power-to-gas in Europe helping integrate renewables. "With a capacity of 480 megawatts each, the world's largest floating energy vessels operate in Indonesia and Ghana. The conversion to gas has been completed in our project in Indonesia. We have also initiated the conversion of the Ghana vessel into gas," she said.

Harezi explained that they would continue to convert their fleets to natural gas in the coming period. "Our 235-MW floating electric vessel, the Ayşegül Sultan, sets sail today to meet 15% of Senegal's electricity needs on its own. After an approximately 20-day cruise, the vessel will reach Dakar, the capital of Senegal, and will begin commercial operation in early October," Harezi continued. "We plan to use liquid fuel as bridging fuel in the first six months. At the end of the first six months, we will start to produce electricity from LNG on our ship. Thus, Ayşegül Sultan will be the first project to generate electricity from LNG in Africa, while the world's most powerful tidal turbine is delivering power to the grid, officials said. Our floating power plant to be sent to Mozambique is designed to generate electricity from LNG. It is also scheduled to start operations in the next year."

Ontario, Quebec to swap energy in new deal to help with electricity demands

Ontario-Quebec Energy Swap streamlines electricity exchange, balancing peak demand across clean grids with hydroelectric and nuclear power, enhancing reliability, capacity banking, and interprovincial load management for industry growth, EV adoption, and seasonal heating-cooling needs.

 

Key Points

10-year, no-cash power swap aligning peaks; hydro and nuclear enhance reliability and let Ontario bank capacity.

✅ Up to 600 MW exchanged yearly; reviews adjust volumes

✅ Peaks differ: summer A/C in Ontario, winter heating in Quebec

✅ Capacity banking enables future-year withdrawals

 

Ontario and Quebec have agreed to swap energy to build on an electricity deal to help each other out when electricity demands peak.

The provinces' electricity operators, the Independent Electricity System Operator holds capacity auctions and Hydro-Quebec, will trade up to 600 megawatts of energy each year, said Ontario Energy Minister Todd Smith.

“The deal just makes a lot of sense from both sides,” Smith said in an interview.

“The beauty as well is that Quebec and Ontario are amongst the cleanest grids around.”

The majority of Ontario's power comes from nuclear energy while the majority of Quebec's energy comes from hydroelectric power, including Labrador power in regional transmission networks.

The deal works because Ontario and Quebec's energy peaks come at different times, Smith said.

Ontario's energy demands spike in the summer, largely driven by air conditioning on hot days, and the province has occasionally set off-peak electricity prices to provide temporary relief, he said.

Quebec's energy needs peak in the winter, mostly due to electric heating on cold days.

The deal will last 10 years, with reviews along the way to adjust energy amounts based on usage.

“With the increase in energy demand, we must adopt more energy efficiency programs like Peak Perks and intelligent measures in order to better manage peak electricity consumption,” Quebec's Energy Minister Pierre Fitzgibbon wrote in a statement.

Smith said the energy deal is a straight swap, with no payments on either side, and won't reduce hydro bills as the transfer could begin as early as this winter.

Ontario will also be able to bank unused energy to save capacity until it is needed in future years, Smith said.

Both provinces are preparing for future energy needs, as electricity demands are expected to grow dramatically in the coming years with increased demand from industry and the rise of electric vehicles, and Ontario has tabled legislation to lower electricity rates to support consumers.

Utility giant Electricite de France acquired 50pc stake in Irish offshore wind farm

Codling Bank Offshore Wind Project will deliver a 1.1 GW offshore wind farm off the Wicklow coast, as EDF Renewables and Fred Olsen Renewables invest billions to support Ireland's CAP 2030 and cut carbon emissions.

 

Key Points

A 1.1 GW offshore wind farm off Co Wicklow, led by EDF and Fred Olsen, advancing Ireland's CAP 2030 targets.

✅ Up to 1.1 GW capacity; hundreds of turbines off Co Wicklow

✅ EDF Renewables partners with Fred Olsen Renewables

✅ Investment well over €2bn, supporting 70% electricity by 2030

 

It’s been previously estimated that the entire Codling Bank project, which will eventually see hundreds of wind turbines, such as a huge offshore wind turbine now coming to market, erected about 13km off the Co Wicklow coast, could be worth as much as €100m. The site is set to generate up to 1.1 gigawatts of electricity when it’s eventually operational.

It’s likely to cost well over €2bn to develop, and with new pipelines abroad where Long Island offshore turbine proposals are advancing, scale economies are increasingly relevant.

The other half of the project is owned by Norway’s Fred Olsen Renewables, with tens of millions of euro already reportedly spent on surveys and other works associated with the scheme. Initial development work started in 2003.

Mr Barrett will now continue to focus on his non-Irish renewable projects, at a time when World Bank wind power support is accelerating in developing countries, said Hazel Shore, the company that sold the stake. It added that Johnny Ronan and Conor Ronan, the developer’s brother, will retain an equity interest in the Codling project.

“The Hazel Shore shareholders remain committed to continuing their renewable and forestry businesses,” noted the firm, whose directors include Paddy Teahon, a former secretary of the Department of the Taoiseach and chairman of the National Offshore Wind Association of Ireland.

The French group’s EDF Renewables subsidiary will now partner with the Norwegian firm to develop and build the Codling Bank project, in a sector widely projected to become a $1 trillion business over the coming decades.

EDF pointed out that the acquisition of the Codling Bank stake comes after the government committed to reducing carbon emissions. A Climate Action Plan launched last year will see renewable projects generating 70pc of Ireland’s electricity by 2030, with more than a third of Irish electricity to be green within four years according to recent analysis. Offshore wind is expected to deliver at least 3.5GW of power in support of the objective.

Bruno Bensasson, EDF Group senior executive vice-president of renewable energies and the CEO of EDF Renewables said the French group is “committed to contributing to the Irish government’s renewables goals”.

“This important project clearly strengthens our strong ambition to be a leading global player in the offshore wind industry,” he added. “This is consistent with the CAP 2030 strategy that aims to double EDF’s renewable energy generation by 2030 and increase it to 50GW net.”

Matthieu Hue, the CEO of EDF Renewables UK and Ireland said the firm already has an office in Dublin and is looking for further renewable projects, as New York's biggest offshore wind farm moves ahead, underscoring momentum.

Last November, the ESB teamed up with EDF in Scotland, reflecting how UK offshore wind is powering up, with the Irish utility buying a 50pc stake in the Neart na Gaoithe offshore wind project. The massive wind farm is expected to generate up to 450MW of electricity and will cost about €2.1bn to develop.

EDF said work on that project is “well under way”.

Bitcoin mining uses so much electricity that 1 city could curtail facility's power during heat waves

Medicine Hat Bitcoin Mining Facility drives massive electricity demand and energy use, leveraging natural gas and nearby wind power; Hut 8 touts economic growth, while critics cite carbon emissions, renewables integration, and climate impact.

 

Key Points

A Hut 8 project in Alberta that mines bitcoin at scale, consuming up to 60 MW and impacting energy and emissions.

✅ Consumes more than 60 MW, rivaling citywide electricity use

✅ Sited by natural gas plant; wind turbines nearby

✅ Economic gains vs. carbon emissions and climate risks

 

On the day of the grand opening of the largest bitcoin mining project in the country, the weather was partly cloudy and 15 C. On a Friday afternoon like this one, the new facility uses as much electricity as all of Medicine Hat, Alta., a city of more than 60,000 people and home to several large industrial plants.

The vast amount of electricity needed for bitcoin mining is why the city of Medicine Hat has championed the economic benefits of the project, while environmentalists say they are wary of the significant energy use.

Toronto-based Hut 8 has spent more than $100 million to develop the 4½-hectare site on the northern edge of the city. It has 56 shipping containers, each filled with 180 computer servers that digitally mine for bitcoin around the clock.

The company said it has already mined more than 3,300 bitcoins in Alberta, including at its much smaller site in Drumheller. On average, the Medicine Hat facility mines about 20 bitcoins per day. The value of bitcoin can fluctuate daily, but has sold recently for around $9,000.

The bitcoin mining facility is located right beside the city of Medicine Hat's new natural gas-fired power plant and four wind turbines are a short distance away. The bitcoin plant can consume more than 60 megawatts of power, more than 10 times more electricity used by any other facility in the city, according to the mayor.

That's why, in the event of a summer heat wave, the city has provisions in place to pull the plug on the electricity it provides to Hut 8, mirroring utility pauses on crypto loads seen elsewhere, so there won't be any blackouts for residents, according to the mayor.

Still, some say the bitcoin mining industry wastes far too much energy

"It's a huge magnitude when you talk about the carbon emissions," said Saeed Kaddoura, an analyst with the Pembina Institute, an environmental think-tank. "Moving forward, there needs to be some consideration on what the environmental impact of this is."

Medicine Hat owns its own natural gas and electricity generation and distribution businesses. The city leases the land to Hut 8 and the facility employs 40 full-time workers. Add up the economic benefits and the city of Medicine Hat will receive a significant financial boost from the new project, says Ted Clugston, the city's mayor.

Financial details of the city's deal with Hut 8 are not disclosed.

For more than a century, the city has attracted business by offering low-cost energy, and the mayor said this project is no different.

"They could have gone anywhere in the world and they chose Medicine Hat," said Clugston. "[Hut 8] is not here for renewable energy because it is not reliable. They need gas-fired generation and we have it in spades."

Environmental groups are concerned by the sheer amount of energy consumed by bitcoin mining, with some utilities warning they can't serve new energy-intensive customers right now, especially in places like Medicine Hat where most of the electricity is produced by fossil fuels.

The bitcoin system is designed, so only a limited number of the cryptocurrency can be mined everyday. Over time, as more miners compete for a decreasing number of available bitcoins, facilities will have to use more electricity compared to the amount of the cryptocurrency they collect.

"The way the bitcoin algorithm works is that it's designed to waste as much electricity as possible. And the more popular bitcoin becomes, the more electricity it wastes," said Keith Stewart, a spokesperson for Greenpeace.

Stewart questions whether natural gas should be used to produce a digital product.

"If you live in Alberta, you want to have heat and light, those types of things. I don't think bitcoin is a necessity of life for anyone," he said.

The CEO of Hut 8 completely disagrees, arguing the cryptocurrency is essential.  

"Bitcoin was created during the financial crisis. It has really served a purpose in terms of providing the opportunity for people who don't necessarily trust their government or their central banks," said Andrew Kiguel.

Clocks are running slow across Europe because of an argument over who pays the electricity bill

European Grid Frequency Clock Slowdown has made appliance clocks run minutes behind as AC frequency drifts on the 50 Hz electricity grid, driven by a Kosovo-Serbia billing dispute and ENTSO-E monitored supply-demand imbalance.

 

Key Points

An EU-wide timing error where 50 Hz AC deviations slow appliance clocks due to Kosovo-Serbia grid imbalances.

✅ Clocks drifted up to six minutes across interconnected Europe

✅ Cause: unpaid power in N. Kosovo, contested by Serbia

✅ ENTSO-E reported 50 Hz deviations from supply-demand mismatch

 

Over the past couple of months, Europeans have noticed time slipping away from them. It’s not just their imaginations: all across the continent, clocks built into home appliances like ovens, microwaves, and coffee makers have been running up to six minutes slow. The unlikely cause? A dispute between Kosovo and Serbia over who pays the electricity bill.

To make sense of all this, you need to know that the clocks in many household devices use the frequency of electricity to keep time. Electric power is delivered to our homes in the form of an alternating current, where the direction of the flow of electricity switches back and forth many times a second. (How this system came to be established is complex, but the advantage is that it allows electricity to be transmitted efficiently.) In Europe, this frequency is 50 Hertz — meaning a current alternating of 50 times a second. In America, it’s 60 Hz, and during peak summer demand utilities often prepare for blackouts as heat drives loads higher.

Since the 1930s, manufacturers have taken advantage of this feature to keep time. Each clock needs a metronome — something with a consistent rhythm that helps space out each second — and an alternating current provides one, saving the cost of extra components. Customers simply set the time on their oven or microwave once, and the frequency keeps it precise.

At least, that’s the theory. But because this timekeeping method is reliant on electrical frequency, when the frequency changes, so do the clocks. That is what has been happening in Europe.

The news was announced this week by ENTSO-E, the agency that oversees the single, huge electricity grid connecting 25 European countries and which recently synchronized with Ukraine to bolster regional resilience. It said that variations in the frequency of the AC caused by imbalances between supply and demand on the grid have been messing with the clocks. The imbalance is itself caused by a political argument between Serbia and Kosovo. “This is a very sensitive dispute that materializes in the energy issues,” Susanne Nies, a spokesperson for ENTSO-E, told The Verge.

Essentially, after Kosovo declared independence from Serbia in 2008, there were long negotiations over custody of utilities like telecoms and electricity infrastructure. As part of the ongoing agreements (Serbia still does not recognize Kosovo as a sovereign state), four Serb-majority districts in the north of Kosovo stopped paying for electricity. Kosovo initially covered this by charging the rest of the country more, but last December, it decided it had had enough and stopped paying. This led to an imbalance: the Kosovan districts were still using electricity, but no one was paying to put it on the grid.

This might sound weird, but it’s because electricity grids work on a system of supply and demand, where surging consumption has even triggered a Nordic grid blockade in response to constrained flows. As Stewart Larque of the UK’s National Grid explains, you want to keep the same amount of electricity going onto the grid from power stations as the amount being taken off by homes and businesses. “Think of it like driving a car up a hill at a constant speed,” Larque told The Verge. “You need to carefully balance acceleration with gravity.” (The UK itself has not been affected by these variations because it runs its own grid.)

 

“THEY ARE FREE-RIDING ON THE SYSTEM.”

This balancing act is hugely complex and requires constant monitoring of supply and demand and communication between electricity companies across Europe, and growing cyber risks have spurred a renewed focus on protecting the U.S. power grid among operators worldwide. The dispute between Kosovo and Serbia, though, has put this system out of whack, as the two governments have been refusing to acknowledge what the other is doing.

“The Serbians [in Kosovo] have, according to our sources, not been paying for their electricity. So they are free-riding on the system,” says Nies.

The dispute came to a temporary resolution on Tuesday, when the Kosovan government stepped up to the plate and agreed to pay a fee of €1 million for the electricity used by the Serb-majority municipalities. “It is a temporary decision but as such saves our network functionality,” said Kosovo’s prime minister Ramush Haradinaj. In the longer term, though, a new agreement will need to be reached.

There have been rumors that the increase in demand from northern Kosovo was caused by cryptocurrency miners moving into the area to take advantage of the free electricity. But according to ENTSO-E, this is not the case. “It is absolutely unrelated to cryptocurrency,” Nies told The Verge. “There’s a lot of speculation about this, and it’s absolutely unrelated.” Representatives of Serbia’s power operator, EMS, refused to answer questions on this.

For now, “Kosovo is in balance again,” says Nies. “They are producing enough [electricity] to supply the population. The next step is to take the system back to normal, which will take several weeks.” In other words, time will return to normal for Europeans — if they remember to change their clocks, even as the U.S. power grid sees more blackouts than other developed nations.
