Canadian researchers have found a new way to harvest energy from the human body, a device that looks like a knee brace but can generate enough power in a relaxed stroll to power half a dozen cell phones.

Volunteers wearing one of the biomechanical energy harvesters on each leg were able to generate 5 watts of electricity with little extra effort, says Max Donelan, an assistant professor in the department of kinesiology at Simon Fraser University in Burnaby, B.C. If they walked quickly they could generate 13 watts.

The harvester looks like an orthopedic knee brace, and Dr. Donelan says it works on the same principle as regenerative breaking in hybrid cars, in which energy normally dissipated during braking drives a generator instead. They rigged a brace with a generator system that can turn physical motion into electrical energy as the hamstring muscle slows down the swinging knee.

“Think of the body as an amazing battery,” Dr. Donelan said in an interview. “The average person stores as much energy in fat as a 1,000 kilogram battery.”

He and his colleagues reported their invention in a recent edition of the prestigious journal Science.

Their harvester generates slightly less power than a backpack invented by University of Pennsylvania biology professor Lawrence Rome so that U.S. marines could power cell phones, night-vision goggles and other equipment without carrying extra batteries.

The backpack takes advantage of the hip's movement to generate electricity, but to produce the power, people have to carry a relatively heavy load. The packs Dr. Rome used in his experiments weighed between 20 and 38 kilograms, to generate up to 7.4 watts of power. He said he is hoping to produce a commercial product that weighs significantly less.

Energy harvesting shoes have also been invented, but are not yet on the market. They collect energy from the motion of walking, but generate only 0.8 Watts of power.

Dr. Donelan has set up a company, Bionic Power Inc., to develop a commercial model of his knee-brace device that should be ready for field testing in a year. The experimental version weights 1.5 kilogram each, but Dr. Donelan says he should be able to make one that is much lighter.

The company is hoping for military clients, says chief executive officer Yad Garcha. The idea is that soldiers would carry one battery to power all their various electronic devices. That battery would be recharged while they walked.

Mr. Garcha won't discuss how much the device would cost, but says right now it is too expensive for the average consumer in the developed world, let alone those in poor countries who now don't have access to electricity.

About a quarter of the world's population lives without an electricity supply, and Dr. Donelan hopes that one day kids in developing countries will be able to use the device to power laptop computers.

“They'll have to take a break from their homework to go outside and play to generate power to do their homework,” he says.

Rescue workers could use it to recharge batteries, he says. So could geologists or other people who work in remote locations.

Electric Ferries Power Up B.C. with CIB Help

BC Ferries Electrification accelerates zero-emission vessels, Canada Infrastructure Bank financing, and fast charging infrastructure to cut greenhouse gas emissions, lower operating costs, and reduce noise across British Columbia's Island-class routes.

 

Key Points

BC Ferries Electrification is the plan to deploy zero-emission ferries and charging, funded by CIB, to reduce emissions.

✅ $75M CIB loan funds four electric ferries and chargers

✅ Cuts 9,000 tonnes CO2e annually on short Island-class routes

✅ Quieter service, lower operating costs, and redeployed hybrids

 

British Columbia is taking a significant step towards a cleaner transportation future with the electrification of its ferry fleet. BC Ferries, the province's ferry operator, has secured a $75 million loan from the Canada Infrastructure Bank (CIB) to fund the purchase of four zero-emission ferries and the necessary charging infrastructure to support them.

This marks a turning point for BC Ferries, which currently operates a fleet reliant on diesel fuel. The new Island-class electric ferries will be deployed on shorter routes, replacing existing hybrid ships on those routes. These hybrid ferries will then be redeployed on routes that haven't yet been converted to electric, maximizing their lifespan and efficiency.

Environmental Benefits

The transition to electric ferries is expected to deliver significant environmental benefits. The new vessels are projected to eliminate an estimated 9,000 tonnes of greenhouse gas emissions annually, and electric ships on the B.C. coast already demonstrate similar gains, contributing to British Columbia's ambitious climate goals. Additionally, the quieter operation of electric ferries will create a more pleasant experience for passengers and reduce noise pollution for nearby communities.

Economic Considerations

The CIB loan plays a crucial role in making this project financially viable. The low-interest rate offered by the CIB will help to keep ferry fares more affordable for passengers. Additionally, the long-term operational costs of electric ferries are expected to be lower than those of diesel-powered vessels, providing economic benefits in the long run.

Challenges and Opportunities

While the electrification of BC Ferries is a positive development, there are some challenges to consider. The upfront costs of electric ferries and charging infrastructure are typically higher than those of traditional options, though projects such as the Kootenay Lake ferry show growing readiness. However, advancements in battery technology are constantly lowering costs, making electric ferries a more cost-effective choice over time.

Moreover, the transition presents opportunities for job creation in the clean energy sector, with complementary initiatives like the hydrogen project broadening demand. The development, construction, and maintenance of electric ferries and charging infrastructure will require skilled workers, potentially creating a new avenue for economic growth in British Columbia.

A Pioneering Example

BC Ferries' electrification initiative sets a strong precedent for other ferry operators worldwide, including Washington State Ferries pursuing hybrid-electric upgrades. This project demonstrates the feasibility and economic viability of transitioning to cleaner marine transportation solutions. As battery technology and charging infrastructure continue to develop, we can expect to see more widespread adoption of electric ferries across the globe.

The collaboration between BC Ferries and the CIB paves the way for a greener future for BC's transportation sector, where efforts like Harbour Air's electric aircraft complement marine electrification. With cleaner air, quieter operation, and a positive impact on climate change, this project is a win for the environment, the economy, and British Columbia as a whole.

Macron: France, Germany to provide each other with gas, electricity, to weather crisis

France-Germany Energy Solidarity underscores EU energy crisis cooperation: gas supply swaps, electricity imports, price cap talks, and curbs on speculation as Russian pipeline flows halt and winter demand rises across the bloc.

 

Key Points

A pact where France sends gas to Germany as Germany supplies power, bolstering EU cooperation and winter security.

✅ Gas to Germany; power to France amid nuclear outages.

✅ EU price cap, anti-speculation, joint gas purchasing.

✅ No new Spain-France pipeline unless case improves.

 

France will send gas to Germany if needed while Germany stands ready to provide it with electricity, President Emmanuel Macron said on Monday, saying this showcased European solidarity in the face of the energy crisis stemming from the war in Ukraine, which many view as a wake-up call to ditch fossil fuels across the bloc.

European gas prices surged, share prices slid and the euro sank on Monday after Russia stopped pumping gas via a major supply route, and Germany's 200 billion euro package sought to cushion the blow, in another warning to the 27-nation EU as it scrambled to respond to the crisis ahead of winter. read more

"Germany needs our gas and we need power from the rest of Europe, notably Germany," France's president told a news conference as EU electricity reform remains under debate following a phone call with German Chancellor Olaf Scholz.

The necessary connections for France to deliver gas to Germany when needed would be finalised in the coming weeks, he said, adding that France, which had long been a net exporter of electricity, will need help from its neighbours because of technical problems its nuclear plants face. read more

Macron, however, said that he did not understand demand for a third gas link between France and Spain, rejecting calls to increase capacity with a new pipeline.

He added he was open to changing his mind on that point, especially as Germany's utility troubles deepen, should Scholz or Prime Minister Pedro Sanchez argue convincingly for it.

Ahead of a meeting on Friday of EU energy ministers, Macron said France was in favour of buying gas at a European rather than a national level, as emergency electricity measures are weighed, and called for European Union measures to control energy prices.

He said it was necessary to act against speculation on energy prices at EU level, as the EU outlines possible gas price cap strategies for discussion, and also said France was in favour of putting a cap on the price of pipeline Russian gas.

Macron also repeated calls for all to turn down air conditioners when it's hot and to limit heating to 19 degrees Celsius this winter, noting that rolling back electricity prices is tougher than it appears this year.

"Everyone has to do their bit," he said.

New bill would close loophole that left hundreds of Kentucky miners with cold checks

Kentucky Coal Wage Protection Bill strengthens performance bond enforcement, links Energy and Environment Cabinet and Labor Cabinet notifications, addresses Blackjewel bankruptcy fallout, safeguards unpaid miners, ties mining permits to payroll bonds, penalizes violators via revocations.

 

Key Points

A Kentucky plan to enforce wage bonds and revoke mining permits to protect miners after bankruptcies.

✅ Requires wage bonds for firms under 5 years

✅ Links Energy and Environment Cabinet and Labor Cabinet

✅ Violators face permit revocation in 90 days

 

Following the high-profile bankruptcy of a coal company that left hundreds of Kentucky miners with bad checks last month, Sen. Johnny Ray Turner (D-Prestonsburg) said he will pre-file a bill Thursday aimed at closing a loophole that allowed the company to operate in violation of state law.

The bill would also compel state agencies to determine whether other companies are currently in violation of the law, and could revoke mining permits if the companies don't comply.

Turner's bill would amend an already-existing law that requires coal and construction companies that have been operating in Kentucky for less than five years to post a performance bond to protect wages if the companies cease their operations.

Blackjewel LLC., which employed hundreds of miners in Eastern Kentucky, failed to post that bond. When it shut its mines down and filed for bankruptcy last month, it left hundreds of miners without payment for 3 weeks and one day of work.

The bond issue has sparked criticism from various state officials, including Attorney General Andy Beshear, who said Tuesday that he would investigate whether other companies are currently in violation, similar to an external investigation of utility workers in another jurisdiction.

Blackjewel issued cold checks to its employees June 28, and when the checks bounced days later, many employees were left with bank accounts overdrawn by more than $1,000. The bankruptcy left many miners and their families with concerns over upcoming bill and mortgage payments, and, as unpaid days off at utilities elsewhere show, the strain on workers can be severe, and fostered a ongoing protest that blocked a train hauling coal from one of the company's Harlan County mines.

Blackjewel had been operating in Kentucky for about two years before it filed for bankruptcy, so it should have paid the performance bond, according to state law.

David A. Dickerson, the Kentucky Labor Cabinet Secretary, said the law as it's currently written does not set up any mechanism that notifies the cabinet, or provides comparable public reporting at large utility projects elsewhere, when a company opens in Kentucky that is supposed to pay the bond.

That allowed Blackjewel to operate for two years without any protection for workers before it closed its mines. Had the company posted the bond according to state law, miners likely would have been paid for the work they had already completed, officials said.

The law requires companies to set aside enough money to cover payroll for four weeks.

Turner's bill would compel the state Energy and Environment Cabinet to notify the Labor Cabinet's Department of Workplace Standards of any application for a mining permit from a company that has been doing business in Kentucky for less than five years.

It also compels the EEC to notify the Labor Cabinet of any companies that already have permits that are subject to the bond.

"It should have already been that way, but I'm happy so our children don't have to go through this," said Jeff Willig, a former Blackjewel miner who helped launch the protest at the railroad.

Willig said he and other miners will continue to block the tracks until they receive payment for their past work.

Any company currently operating in violation of the law would have 90 days to become compliant before its mining permits are revoked. New companies that are applying for permits will be required post the bond before permits are issued.

"Hopefully it will take care of the loopholes that had been exploited by Blackjewel," Turner said.

The bill will be taken up by the legislature when it returns to session in January. It would also cover attorneys' fees if workers are forced to sue their employer to cover wages, underscoring broader worker safety concerns during health emergencies.

Turner said he has reached out to Republican leadership in the Senate, and expects the bill to have bipartisan support come January.

Turner announced the legislation at a press conference in Harlan, the county with the highest population of Blackjewel employees affected by the bankruptcy, and as prolonged utility outages after tornadoes have strained other Kentucky communities.

State rep. Angie Hatton (D-Whitesburg) was also in attendance, along with rep. Chris Fugate (R-Chavies) and state Sen. Morgan McGarvey (D-Louisville).

Hatton said the bankruptcy has had serious economic impact throughout Eastern Kentucky, including in Letcher County, which is home to more than 130 former Blackjewel workers.

"This is something that has done a lot of damage to Eastern Kentucky," Hatton said.

Hatton plans to file the same bill in the state House of Representatives.

Fugate commended community members in Harlan County and elsewhere who have banded together in support of the miners by donating children's clothing, school supplies, food and other goods, while other regions have created a coal transition fund to help displaced workers.

Mosley called the bankruptcy "totally unprecedented" and said the current performance bond law, which has been on-the-books since 1986, lacked the enforcement necessary to protect miners in bankruptcies like Blackjewel's, even as a workplace safety fine in another case shows regulatory consequences in other industries.

"There was a law, there wasn't good enough process," Mosley said.

Blackjewel received court approval to sell many of its mines last month, including many in Kentucky, to Kopper Glo Mining, LLC.

As part of the sale agreement, Kopper Glo said it would pay $450,000 to cover the past wages of Blackjewel miners, and collect a per ton fee accumulating up to $550,000 that it will also contribute to pay back wages.

That total $1 million is less than half of all back wages owed to Blackjewel miners, but attorneys who filed a class action suit against the company said miners have a priority lien on the purchase price. That could allow former Blackjewel employees to make good on their back wages as bankruptcy proceedings continue.

Mosley said he spoke with a Kopper Glo official Thursday, who said the company is working to re-open the mines as quickly as possible. The official did not give an exact timeline.

27 giant parts from China to be transported to wind farm in Saskatchewan

Port of Vancouver Wind Turbine Blades arrive from China for a Saskatchewan wind farm, showcasing record oversized cargo logistics, tandem crane handling, renewable energy capacity, and North America's longest blades from Goldwind.

 

Key Points

Record-length blades for a Canadian wind farm, boosting renewable energy and requiring heavy-lift logistics at the port.

✅ 27 blades unloaded via tandem cranes with cage supports

✅ 50 turbines headed to Assiniboia over 21 weeks

✅ Largest 250 ft blades to arrive; reduced CO2 vs coal

 

A set of 220-foot-long wind turbine blades arrived at the Port of Vancouver from China over the weekend as part a shipment bound for a wind farm in Canada, alongside BC generating stations coming online in the region.

They’re the largest blades ever handled by the port, and this summer, even larger blades will arrive as companies expand production such as GE’s blade factory in France to meet demand — the largest North America has ever seen.

Alex Strogen described the scene as crews used two tandem cranes to unload 27 giant white blades from the MV Star Kilimanjaro, which picked up the wind turbine assemblies in China. They were manufactured by Goldwind Co.

“When you see these things come off and put onto these trailers, it’s exceptional in the sheer length of them,” Strogen said. “It looks as long as an airplane.”

In fact, each blade is about as long as the wingspan of a Boeing 747.

Groups of longshoremen attached the cranes to each blade and hoisted it into the air and onto a waiting truck. Metal cage-like devices on both ends kept the blades from touching the ground. Once loaded onto the trucks, the blades and shaft parts head to a terminal to be unloaded by another group of workers.

Another fleet of trucks will drive the wind turbines, towers and blades to Assiniboia, Saskatchewan, Canada, over the course of 21 weeks. Potentia Renewables of Toronto is erecting the turbines on 34,000 acres of leased agriculture land, amid wind farm expansion in PEI elsewhere in the country, according to a news release from the Port of Vancouver.

Potentia’s project, called the Golden South Wind Project, will generate approximately 900,000 megawatt-hours of electricity. It also has greatly reduced CO2 emissions compared with a coal-fired plant, and complements tidal power in Nova Scotia in Canada’s clean energy mix, according to the news release.

The project is expected to be operating in 2021, similar to major UK offshore wind additions coming online.

The Port of Vancouver will receive 50 full turbines of two models for the project, as Manitoba invests in new turbines across Canada. In August, the larger of the models, with blades measuring 250 feet, will arrive. They’ll be the longest blades ever imported into any port in North America.

“It’s an exciting year for the port,” said Ryan Hart, chief external affairs officer.

The Port of Vancouver is following all the recommended safety precautions during the COVID-19 pandemic, including social distancing and face masks, Strogen said, with support from initiatives like Bruce Power’s PPE donation across Canada.
As for crews onboard the ships, the U.S. Coast Guard is the agency in charge, and it is monitoring the last port-of-call for all vessels seeking to enter the Columbia River, Hart wrote in an email.

Vessel masters on each ship are responsible for monitoring the health of the crew and are required to report sick or ill crew members to the USCG prior to arrival or face fines and potential arrest.

Senate Committee Advised by WIRES Counsel That Electric Transmission Still Faces Barriers to Development

U.S. Transmission Grid Modernization underscores FERC policy certainty, high-voltage infrastructure upgrades, renewables integration, electrification, and grid resilience to cut congestion and enable distributed energy resources, safeguarding against extreme weather, cyber threats, and market volatility.

 

Key Points

A plan to expand, upgrade, and secure high-voltage networks for renewables integration, electrification, reliability.

✅ Replace aging lines to cut congestion and customer costs

✅ Integrate renewables and distributed energy resources at scale

✅ Enhance resilience to weather, cyber, and physical threats

 

Today, in a high-visibility hearing on U.S. energy delivery infrastructure before the United States Senate Committee on Energy and Natural Resources, WIRES Executive Director and Former FERC Chairman Jim Hoecker addressed the challenges and opportunities that confront the modern high-voltage grid as the industry strives to upgrade and expand it to meet the demands of consumers and the economy.

In prepared testimony and responses to Senators' questions, Hoecker urged the Committee to support industry efforts to expand and upgrade the transmission network and to help regulators, especially the Federal Energy Regulatory Commission (FERC action on aggregated DERs), promote certainty and predictability in energy policy and regulation. 

 

His testimony stressed these points:

Significant transmission investment is needed now to replace aging infrastructure like the aging grid risks to clean energy, reduce congestion costs, and deliver widespread benefits to customers.

Increasingly, the role of the transmission grid is to integrate new distributed resources and renewable energy into the electric system and make them available to the market.

The changing electric generation mix, including needed nuclear innovation, and the coming electrification of transportation, heating, and other segments of the American economy in the next quarter century will depend on a strong and adaptable electric system. A robust transmission grid will be the linchpin that will enable us to meet those demands.

"Transmission is the common element that will support all future electricity needs and provide a hedge against uncertainties and potential costly outcomes. The time is now to be proactive in encouraging additional investments in our nation's most crucial infrastructure: the electric transmission system," Hoecker said. 

Hoecker's testimony also emphasized that transmission investment will contribute to the overall resilience of the electric system by bringing multiple resources and technologies to bear on threats to the power system, including extreme weather and proposals like a wildfire-resilient grid bill, cyber or physical attacks, or other events. Visit WIRES website for recently filed comments on the subject (supported by a Brattle Group study). 

"Transmission gives us the optionality to adapt to whatever the future holds, and a modern and resilient transmission system, informed by Texas reliability improvements, will be the most valuable energy asset we have," says Nina Plaushin, president of WIRES and vice president of federal affairs, regulatory and communications for ITC Holdings Corp. 

Hoecker closed his testimony by emphasizing that the "electrification" scenario that is being discussed across multiple industries demands action now in order to ensure policy and regulatory certainty that will support needed transmission investment. More studies need to be conducted to better understand and define how this delivery network must be configured and planned in anticipation of this potential transformation in how we use electrical energy.

COVID-19 Response: Electric Power Industry Closely Coordinating With Federal Partners

ESCC COVID-19 Response coordinates utilities, public power, and cooperatives to protect the energy grid and electricity reliability, aligning with DOE, DHS, CDC, FERC, and NERC on continuity of operations, mutual assistance, and supply chain resilience.

 

Key Points

An industry government effort ensuring reliability, operations continuity and supply chain stability during COVID-19.

✅ Twice weekly ESCC calls align DOE, DHS, HHS, CDC, FERC, NERC priorities.

✅ Focus on control centers, generation, quarantine access, mutual aid.

✅ Resource Guide supports localized decisions and supply chain resilience.

 

The nation’s investor-owned electric companies, public power utilities, and electric cooperatives are working together to protect the energy grid as the U.S. grid addresses COVID-19 challenges and ensure continued access to safe and reliable electricity during the COVID-19 global health crisis.

The electric power industry has been planning for years, including extensive disaster planning across utilities, for an emergency like the COVID-19 pandemic, as well as countless other types of emergencies, and the industry is coordinating closely with government partners through the Electricity Subsector Coordinating Council (ESCC) to ensure that organizations have the resources they need to keep the lights on.

The ESCC is holding high-level coordination calls twice a week with senior leadership from the Departments of Energy, Homeland Security, and Health and Human Services, the Centers for Disease Control and Prevention, the Federal Energy Regulatory Commission, and the North American Electric Reliability Corporation. These calls help ensure that industry and government work together to resolve any challenges that arise during this health emergency and that electricity remains safe for customers.

“Electricity and the energy grid are indispensable to our society, and one of our greatest strengths as an industry is our ability to convene and adapt quickly to changing circumstances and challenging events,” said Edison Electric Institute President Tom Kuhn. “Our industry plans for all types of contingencies, with examples such as local response planning, and strong industry-government coordination and cross-sector collaboration are critical to our planning and response. We appreciate the ongoing leadership and support of our government partners as we all respond to COVID-19 and power through this crisis together.”

The ESCC quickly mobilized and established strategic working groups dedicated to identifying and solving for short-, medium-, and long-term issues facing the industry during the COVID-19 pandemic, with utilities implementing necessary precautions to maintain service across regions.

The five current areas of focus are:

1. Continuity of operations at control centers, including on-site staff lockdowns when needed
2. Continuity of operations at generation facilities
3. Access to, and operations in, restricted or quarantined areas
4. Protocols for mutual assistance
5. Supply chain challenges

“The electric power industry has taken steps to prepare for the evolving coronavirus challenges, while maintaining our commitment to the communities we serve, including customer relief efforts announced by some providers,” said National Rural Electric Cooperative Association CEO Jim Matheson. “We have a strong track record of preparing for many kinds of emergencies that could impact the ability to generate and deliver electricity. While planning for this situation is unique from other business continuity planning, we are taking actions to prepare to operate with a smaller workforce, potential disruptions in the supply chain, and limited support services for an extended period of time.”

The ESCC has developed a COVID-19 Resource Guide linked here and available at electricitysubsector.org. This document was designed to support electric power industry leaders in making informed localized decisions in response to this evolving health crisis. The guide will evolve as additional recommended practices are identified and as more is learned about appropriate mitigation strategies.

“The American Public Power Association (APPA) continues to work with our communityowned public power members and our industry and government partners to gather and share upto-date information, best practices, and guidance to support them in safely maintaining operational integrity,” said APPA CEO Joy Ditto.
