Urban Piezoelectric Energy Textiles capture wind-driven motion on tunnels, bridges, and facades, enabling renewable microgeneration for smart cities with decentralized power, resilient infrastructure, and flexible lamellae sheets that harvest airflow vibrations.

 

Key Points

Flexible piezoelectric sheets that convert urban wind and vibration into electricity on tunnels, bridges, and facades.

✅ Installed on London Crossrail to test airflow energy capture

✅ Flexible lamellae panels retrofit tunnels, bridges, facades

✅ Supports decentralized, resilient urban microgrids

 

Charlotte Slingsby and her startup Moya Power are researching piezo-electric textiles that gain energy from movement, similar to advances like a carbon nanotube energy harvester being explored by materials researchers. It seems logical that Slingsby originally came from a city with a reputation for being windy: “In Cape Town, wind is an energy source that you cannot ignore,” says the 27-year-old, who now lives in London.

Thanks to her home city, she also knows about power failures. That’s why she came up with the idea of not only harnessing wind as an alternative energy source by setting up wind farms in the countryside or at sea, but also for capturing it in cities using existing infrastructure.

 

The problem

The United Nations estimates that by 2050, two thirds of the world’s population will live in cities. As a result, the demand for energy in urban areas will increase dramatically, spurring interest in nighttime renewable technology that can operate when solar and wind are variable. Can the old infrastructure grow fast enough to meet demand? How might we decentralise power generation, moving it closer to the residents who need it?

For a pilot project, she has already installed grids of lamellae-covered plastic sheets in tunnels on London Crossrail routes; the draft in the tube causes the protrusions to flutter, which then generates electricity.

“If we all live in cities that need electricity, we need to look for new, creative ways to generate it, including nighttime solar cells that harvest radiative cooling,” says Slingsby, who studied design and engineering at Imperial College and the Royal College of Art. “I wanted to create something that works in different situations and that can be flexibly adapted, whether you live in an urban hut or a high-rise.”

The yield is low compared to traditional wind power plants and is not able to power whole cities, but Slingsby sees Moya Power as just a single element in a mixture of urban energy sources, alongside approaches like gravity power that aid grid decarbonization.

In the future, Slingsby’s invention could hang on skyscrapers, in tunnels or on bridges – capturing power in the windiest parts of the city, alongside emerging air-powered generators that draw energy from humidity. The grey concrete of tunnels and urban railway cuttings could become our cities’ most visually appealing surfaces...

The gloves are off - Alberta suspends electricity purchase talks with B.C.

Alberta-BC Pipeline Dispute centers on Trans Mountain expansion, diluted bitumen shipments, federal approval, spill response capacity, and electricity trade, as Alberta suspends power talks and Ottawa insists the Kinder Morgan project proceeds in national interest.

 

Key Points

Dispute over Trans Mountain expansion, bitumen limits, and jurisdiction between Alberta, B.C., and Canada.

✅ Alberta suspends BC electricity talks as leverage

✅ Ottawa affirms federal approval and spill response

✅ BC plans advisory panel on diluted bitumen risks

 

Alberta Premier Rachel Notley says her government is suspending talks with British Columbia on the purchase of electricity from the western province.

It’s the first step in Alberta’s fight against the B.C. government’s proposal to obstruct the Kinder Morgan oil pipeline expansion project by banning increased shipments of diluted bitumen to the province’s coast.

Up to $500 million annually for B.C.’s coffers from electricity exports hangs in the balance, Notley said.

“We’re prepared to do what it takes to get this pipeline built — whatever it takes,” she told a news conference Thursday after speaking with Prime Minister Justin Trudeau on the phone.

Notley said she told Trudeau, who’s in Edmonton for a town-hall meeting, that the federal government needs to act decisively to end the dispute.

Speaking on Edmonton talk radio station CHED earlier in the day, Trudeau said the pipeline expansion is in the national interest and will go ahead, even as the federal government undertakes a study on electrification across sectors.

“That pipeline is going to get built,” Trudeau said. “We will stand by our decision. We will ensure that the Kinder Morgan pipeline gets built.”

B.C.’s environment minister has said his minority government plans to ban increased shipments until it can determine that shippers are prepared and able to properly clean up a spill, and, separately, has implemented an electricity rate freeze affecting consumers. He said he will establish an independent scientific advisory panel to study the issue.

The move infuriated Notley, who has accused B.C. of trying to change the rules after the federal government gave the project the green light. B.C. has the right to regulate how any spills would be cleaned up, but can’t dictate what flows through pipelines, she said.

Trudeau said Canada needs to get Alberta’s oil safely to markets other than the U.S. energy market today. He said the federal government did the research and has spent billions on spill response.

“The Kinder Morgan pipeline is not a danger to the B.C. coast,” he said.

Notley said she thanked Trudeau for his assurance that the project will go ahead, but the federal government has to do more to ensure the pipeline’s expansion.

“This is not an Alberta-B.C. issue. This is a Canada-B.C. issue,” she said. “This kind of uncertainty is bad for investment and bad for working people

“Enough is enough. We need to get these things built.”

B.C. Premier John Horgan said his government consulted Alberta and Ottawa about his province’s intentions, noting that Columbia River Treaty talks also shape regional electricity policy.

“I don’t see what the problem is,” Horgan said Thursday at a school opening north of Kelowna, B.C. “It’s within our jurisdiction to put in place regulations to protect the public interest.

“That’s what we are doing.”

He downplayed any possibility of court action or sanctions by Alberta.

“There’s nothing to take to court,” Horgan said. “We are consulting with the people of B.C. It’s way too premature to talk about those sorts of issues.

“Sabre-rattling doesn’t get you very far.”

Speaking in Ottawa, Natural Resources Minister Jim Carr wouldn’t say what Canada might do if British Columbia implements its regulation.

“That’s speculative,” said Carr.

He noted at this point, B.C. has just pledged to consult. He said the federal government heard from thousands of people before the pipeline was approved.

“That’s what they have announced — an intention to consult. We have already consulted.”

B.C.’s proposal creates more uncertainty for Kinder Morgan’s already-delayed Trans Mountain expansion project that would nearly triple the capacity of its pipeline system to 890,000 barrels a day.

Wind and Solar Double Global Share of Electricity in Five Years

Wind And Solar Energy Growth is reshaping the global power mix, accelerating grid decarbonization as coal declines; boosted by pandemic demand drops, renewables now supply near 10% of electricity, advancing climate targets toward net-zero trajectories.

 

Key Points

It is the rise in wind and solar's share of electricity, driving decarbonization and displacing coal globally.

✅ Share doubled in five years across 83% of global electricity

✅ Coal's share fell; renewables neared 10% in H1 2020

✅ Growth still insufficient for 1.5 C; needs ~13% coal cuts yearly

 

Wind and solar energy doubled its share of the global power mix over the last five years, with renewable power records underscoring the trend, moving the world closer to a path that would limit the worst effects of global warming.

The sources of renewable energy made up nearly 10% of power in most parts of the world in the first half of this year, according to analysis from U.K. environmental group Ember, while globally over 30% of electricity is renewable in broader assessments.

That decarbonization of the power grid was boosted this year as shutdowns to contain the coronavirus reduced demand overall, leaving renewables to pick up the slack.

Ember analyzed generation in 48 countries that represent 83% of global electricity. The data showed wind and solar power increased 14% in the first half of 2020 compared with the same period last year while global demand fell 3% because of the impact of the coronavirus.

At the same time that wind turbines and solar panels have proliferated, coal’s share of the mix has fallen around the world. In some, mainly western European countries, where renewables surpassed fossil fuels, coal has been all but eliminated from electricity generation.


China relied on the dirtiest fossil fuel for 68% of its power five years ago, and solar PV growth in China has accelerated since then. That share dipped to 62% this year and renewables made up 10% of all electricity generated.

Still, the growth of renewables may not be going fast enough for the world to hit its climate goals, even as the U.S. is projected to have one-fourth of electricity from renewables soon, and coal is still being burnt for power in many parts of the world.

Coal use needs to fall by about 79% by 2030 from last year’s levels - a fall of 13% every year throughout the decade to come, and in the U.S. renewable electricity surpassed coal in 2022, Ember said.

New installations of wind farms are set to hold more or less steady in the next five years, according to data from BloombergNEF on deployment trends. That will make it difficult to realize a sustained pace of doubling renewable power every five years.

“If your expectations are that we need to be on target for 1.5 degrees, clearly we’re not going fast enough,” said Dave Jones, an analyst at Ember. “We’re not on a trajectory where we’re reducing coal emissions fast enough.”

'Transformative change': Wind-generated electricity starting to outpace coal in Alberta

Alberta wind power surpasses coal as AESO reports record renewable energy feeding the grid, with natural gas conversions, solar growth, energy storage, and decarbonization momentum lowering carbon intensity across Alberta's electricity system.

 

Key Points

AESO data shows wind surpassing coal in Alberta, driven by coal retirements, gas conversions, and growing renewables.

✅ AESO reports wind output above coal several times this week

✅ Coal units retire or convert to natural gas, boosting renewables

✅ Carbon intensity falls; storage and solar improve grid reliability

 

Marking a significant shift in Alberta energy history, wind generation trends provided more power to the province's energy grid than coal several times this week.

According to data from the Alberta Energy System Operator (AESO) released this week, wind generation units contributed more energy to the grid than coal at times for several days. On Friday afternoon, wind farms contributed more than 1,700 megawatts of power to the grid, compared to around 1,260 megawatts from coal stations.

"The grid is going through a period of transformative change when we look at the generation fleet, specifically as it relates to the coal assets in the province," Mike Deising, AESO spokesperson, told CTV News in an interview.

The shift in electricity generation comes as more coal plants come offline in Alberta, or transition to cleaner energy through natural gas generation, including the last of TransAlta's units at the Keephills Plant west of Edmonton.

Only three coal generation stations remain online in the province, at the Genesee plant southwest of Edmonton, as the coal phase-out timeline advances. Less available coal power, means renewable energy like wind and solar make up a greater portion of the grid.

 

EVOLUTION OF THE GRID
"Our grid is changing, and it's evolving," Deising said, adding that more units have converted to natural gas and companies are making significant investments into solar and wind energy.

For energy analyst Kevin Birn with IHS Markit, that trend is only going to continue.

"What we've seen for the last 24 to 36 months is a dramatic acceleration in ambition, policy, and projects globally around cleaner forms of energy or lower carbon forms of energy," Birn said.

Birn, who is also chief analyst of Canadian Oil Markets, added that not only has the public appetite for cleaner energy helped fuel the shift, but technological advancements have made renewables like wind and solar more cost-efficient.

"Alberta was traditionally heavily coal-reliant," he said. "(Now) western Canada has quite a diverse energy base."


LESS CARBON-INTENSIVE
According to Birn, the shift in energy production marks a significant reduction in carbon emissions as Alberta progresses toward its last coal plant closure milestone.

Ten years ago, IHS Markit estimates that Alberta's grid contributed about 900 kilograms of carbon dioxide equivalent per megawatt-hour of energy generation.

"That (figure is) really representing the dominance and role of coal in that grid," Birn said.

Current estimates show that figure is closer to 600 kilograms of CO2 equivalent.

"That means the power you and I are using is less carbon-intensive," Birn said, adding that figure will continue to fall over the next couple of years.


RENEWABLES HERE TO STAY
While many debate whether Alberta's energy is getting clean enough fast enough, Birn believes change is coming.

"It's been a half-decade of incredible price volatility in the oil market which had really dominated this sector and region," the analyst said.

"When I think of the future, I see the power sector building on large-scale renewables, which means decarbonization, and that provides an opportunity for those tech companies looking for clean energy places to land facilities."

Coal and natural gas are considered baseline assets by the AESO, where generation capacity does not shift dramatically, though some utilities report declining coal returns in other markets.

"Wind is a variable resource. It will generate when the wind is blowing, and it obviously won't when the wind is not," Deising said. "Wind and solar can ramp quickly, but they can drop off quite quickly, and we have to be prepared.

"We factor that into our daily planning and assessments," he added. "We follow those trends and know where the renewables are going to show up on the system, how many renewables are going to show up."

Deising says one wind plant in Alberta currently has an energy storage capacity to preserve renewably generated electricity during summer demand records and peak hours as needed. As the technology becomes more affordable, he expects more plants to follow suit.

"As a system operator, our job is to make sure as (the grid) is evolving we can continue to provide reliable power to Albertans at every moment every day," Deising said. "We just have to watch the system more carefully."

The German economy used to be the envy of the world. What happened?

Germany's Economic Downturn reflects an energy crisis, deindustrialization risks, export weakness, and manufacturing stress, amid Russia gas loss, IMF and EU recession forecasts, and debates over electricity price caps and green transition.

 

Key Points

An economic contraction from energy price shocks, export weakness, and bottlenecks in manufacturing and digitization.

✅ Energy shock after loss of cheap Russian gas

✅ Exports slump amid China slowdown and weak demand

✅ Policy gridlock on power price cap and permits

 

Germany went from envy of the world to the worst-performing major developed economy. What happened?

For most of this century, Germany racked up one economic success after another, dominating global markets for high-end products like luxury cars and industrial machinery, selling so much to the rest of the world that half the economy ran on exports.

Jobs were plentiful, the government’s financial coffers grew as other European countries drowned in debt, and books were written about what other countries could learn from Germany.

No longer. Now, Germany is the world’s worst-performing major developed economy, with both the International Monetary Fund and European Union expecting it to shrink this year.

It follows Russia’s invasion of Ukraine and the loss of Moscow’s cheap Russian gas that underpinned industry — an unprecedented shock to Germany’s energy-intensive industries, long the manufacturing powerhouse of Europe.

The sudden underperformance by Europe’s largest economy has set off a wave of criticism, handwringing and debate about the way forward.

Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, said Christian Kullmann, CEO of major German chemical company Evonik Industries AG.

From his 21st-floor office in the west German town of Essen, Kullmann points out the symbols of earlier success across the historic Ruhr Valley industrial region: smokestacks from metal plants, giant heaps of waste from now-shuttered coal mines, a massive BP oil refinery and Evonik’s sprawling chemical production facility.

These days, the former mining region, where coal dust once blackened hanging laundry, is a symbol of the energy transition, as the power sector’s balancing act continues with wind turbines and green space.

The loss of cheap Russian natural gas needed to power factories “painfully damaged the business model of the German economy,” Kullmann told The Associated Press. “We’re in a situation where we’re being strongly affected — damaged — by external factors.”

After Russia cut off most of its gas to the European Union, spurring an energy crisis in the 27-nation bloc that had sourced 40% of the fuel from Moscow, the German government asked Evonik to turn to coal by keeping its 1960s coal-fired power plant running a few months longer.

The company is shifting away from the plant — whose 40-story smokestack fuels production of plastics and other goods — to two gas-fired generators that can later run on hydrogen amid plans to become carbon neutral by 2030 and following the nuclear phase-out of recent years.

One hotly debated solution: a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition, amid an energy crisis that even saw a temporary nuclear extension to stabilize supply.

The proposal from Vice Chancellor Robert Habeck of the Greens Party has faced resistance from Chancellor Olaf Scholz, a Social Democrat, and pro-business coalition partner the Free Democrats. Environmentalists say it would only prolong reliance on fossil fuels, while others advocate a nuclear option to meet climate goals.

Kullmann is for it: “It was mistaken political decisions that primarily developed and influenced these high energy costs. And it can’t now be that German industry, German workers should be stuck with the bill.”

The price of gas is roughly double what it was in 2021, with a senior official arguing nuclear would do little to solve that gas issue, hurting companies that need it to keep glass or metal red-hot and molten 24 hours a day to make glass, paper and metal coatings used in buildings and cars.

A second blow came as key trade partner China experiences a slowdown after several decades of strong economic growth.

These outside shocks have exposed cracks in Germany’s foundation that were ignored during years of success, including lagging use of digital technology in government and business and a lengthy process to get badly needed renewable energy projects approved.

Solar changing shape of electricity prices in Northern Europe

EU Solar Impact on Electricity Prices highlights how rising solar PV penetration drives negative pricing, shifts peak hours, pressures wholesale markets, and challenges grid balancing, interconnection, and flexibility amid changing demand and renewables growth.

 

Key Points

Explains how rising solar PV cuts wholesale prices, shifts negative-price hours, and strains grid flexibility.

✅ Negative pricing events surge with higher solar penetration.

✅ Afternoon price dips replace night-time wind-led lows.

✅ Grid balancing, interconnectors, and flexibility become critical.

 

The latest EU electricity market report has confirmed the affect deeper penetration of solar is having on wholesale electricity prices more broadly.

The Quarterly Report on European Electricity Markets for the final three months of last year noted the number of periods of negative electricity pricing doubled from 2019, to almost 1,600 such events, as global renewables set new records in deployment across markets.

Having experienced just three negative price events in 2019, the Netherlands recorded almost 100 last year “amid a dramatic increase in solar PV capacity,” in the nation, according to the report.

Whilst stressing the exceptional nature of the Covid-19 pandemic on power consumption patterns, the quarterly update also noted a shift in the hours during which negative electric pricing occurred in renewables poster child Germany. Previously such events were most common at night, during periods of high wind speed and low demand, but 2020 saw a switch to afternoon negative pricing. “Thus,” stated the report, “solar PV became the main driver behind prices falling into negative territory in the German market in 2020, as Germany's solar boost accelerated, and also put afternoon prices under pressure generally.”

The report also highlighted two instances of scarce electricity–in mid September and on December 9–as evidence of the problems associated with accommodating a rising proportion of intermittent clean energy capacity into the grid, and called for more joined-up cross-border power networks, amid pushback from Russian oil and gas across the continent.

Rising solar generation–along with higher gas output, year on year–also helped the Netherlands generate a net surplus of electricity last year, after being a net importer “for many years.” The EU report also noted a beneficial effect of rising solar generation capacity on Hungary‘s national electricity account, and cited a solar “boom” in that country and Poland, mirroring rapid solar PV growth in China in recent years.

With Covid-19 falls in demand helping renewables generate more of Europe's electricity (39%) than fossil fuels (36%) for the first time, as renewables surpassed fossil fuels across Europe, the market report observed the 5% of the bloc's power produced from solar closed in on the 6% accounted for by hard coal. In the final three months of the year, European solar output rose 12%, year on year, to 18 TWh and “the increase was almost single-handedly driven by Spain,” the study added.

With coal and lignite-fired power plunging 22% last year across the bloc, it is estimated the European power sector reduced its carbon footprint 14% as part of Europe's green surge although the quarterly report warned cold weather, lower wind speeds and rising gas prices in the opening months of this year are likely to see carbon emissions rebound.

There was good news on the transport front, though, with the report stating the scale of the European “electrically-charged vehicle” fleet doubled in 2020, to 2 million, with almost half a million of the new registrations arriving in the final months of the year. That meant cars with plug sockets accounted for a remarkable 17% of new purchases in Q4, twice the proportion seen in China and a slice of the pie six times bigger than such products claimed in the U.S.

New York State Moratorium on Utility Disconnections During Emergencies

New York Utility Disconnection Ban protects residents during state emergencies, covering electric, gas, water, telecommunications, cable, and internet services, with penalties for noncompliance and options like deferred payment agreements and consumer protections.

 

Key Points

A proposed law barring shutoffs in state emergencies across electric, gas, water, telecom, cable, and internet.

✅ Applies during declared state and local emergencies statewide.

✅ Covers electric, gas, water, telecom, cable, and internet services.

✅ Noncompliance triggers penalties; payment plans required for arrears.

 

Governor Andrew M. Cuomo has announced a proposal to prohibit utility disconnections in regions that are under a state of emergency, addressing the energy insecurity many households face, as part of the 2021 State of the State. The Governor will propose legislation that will apply to electric, gas, water, telecommunications, cable and internet services. Utilities that fail to comply will be subject to penalties.

“In a year in which we dealt with an unprecedented pandemic, ferocious storms added insult to injury by knocking out power for hundreds of thousands of New Yorkers,” Governor Cuomo said. “Utility companies provide essential services, and we need to make sure they continue to provide them, rain or shine. That’s why we’re proposing legislation to make sure that New Yorkers, especially those living in regions under states of emergency, have access to these critical services to provide for themselves and their families.”

Governor Cuomo has taken a series of actions to protect New Yorkers’ access to utilities during the COVID-19 pandemic, including a suspension of shut-offs in New York and New Jersey, among other measures. Last year, the Governor signed legislation extending a moratorium that prevents utility companies from disconnecting utilities to residential households that are struggling with their bills due to the COVID-19 pandemic, a move mirrored by reconnection efforts in Ontario by Hydro One. Utility companies must instead offer these individuals a deferred payment agreement on any past-due balance. 

On November 19, Governor Cuomo announced that Con Edison now faces $25 million in penalties and possible license revocation from the New York State Public Service Commission, amid a broader review of retail energy markets by state regulators, following an investigation into the utility’s failed response during large-scale power outages in Manhattan and Brooklyn in July 2019. On November 2, Governor Cuomo announced that more than $328 million in home heating aid is now available, similar to Ontario bill support during the pandemic, for low- and middle-income New Yorkers who need assistance keeping their homes warm during the coming winter season.

The Governor has previously enacted some of the strongest and most progressive consumer protection and assistance programs in the country, including smart streetlights in Syracuse that reduce energy costs, and other initiatives. Governor Cuomo established New York’s energy affordability policy in 2016, as states pursue renewable energy ambitions that can affect rates, underscoring the need for affordability. The policy extended energy bill support to more than 152,000 additional New York families, ensuring that more than 920,000 New York families spend no more than 6 percent of their income on energy bills. Through this program, New York commits more than $238 million annually helping to keep the lights and heat on for our most vulnerable New Yorkers, while actively striving to expand coverage to additional families.
