Physicists have developed a way to turn heat into sound and then electricity, suggesting a new way to effectively recycle waste energy.

“We are converting waste heat to electricity in an efficient, simple way by using sound,” said the scientist who led the effort, Orest Symko of the University of Utah. “It is a new source of renewable energy from waste heat.”

Symko’s recycling devices are cylinder-shaped “resonators” that fit in the palm of your hand. Each cylinder contains a stack of material with a large surface area — such as metal or plastic plates, or fibers made of glass, cotton or steel wool — placed between cold and hot heat exchangers.

When heat is applied, the heat builds to a particular threshold where hot, moving air produces sound at a single frequency — like air blown into a flute.

“You have heat, which is so disorderly and chaotic, and all of a sudden you have sound coming out at one frequency,” Symko said.

The sound waves then squeeze what is called a piezoelectric device (“piezo” means pressure or squeezing). The pressure created produces an electric voltage. Symko says it is similar to when you hit your "funnybone" or the nerve on outside of your elbow, thereby generating  that weird, painful pinch, which is actually an electrical nerve impulse.

Symko plans to test the devices within a year at a military radar facility and the University of UtahÂ’s hot-water-generating plant. (The U.S. Army funded the study in hopes the technology can be used to create a portable source of energy.)

Symko expects these devices could be used within two years as an alternative to the photovoltaic cells that currently convert sunlight into electricity, and could also provide a new way to cool laptops and other computers, and a to generate electricity from the heat released by nuclear power plant cooling towers.

Former B.C. Hydro CEO earns half a million without working a single day

B.C. Hydro Salary Continuance Payout spotlights executive compensation, severance, and governance at a Crown corporation after a firing, citing financial disclosure reports, Site C dam ties, and a leadership change under a new government.

 

Key Points

Severance-style pay for B.C. Hydro's fired CEO, via salary continuance and disclosed in public filings.

✅ $541,615 total compensation without working days

✅ Salary continuance after NDP firing; financial disclosures

✅ Later named Canada Post interim CEO amid strike

 

Former B.C. Hydro president and chief executive officer Jessica McDonald received a total of $541,615 in compensation during the 2017-2018 fiscal year, a figure that sits amid wider debates over executive pay at utilities such as Hydro One CEO pay at the provincial utility, without having worked a single day for the Crown corporation.

She earned this money under a compensation package after the in-coming New Democratic government of John Horgan fired her, a move comparable to Ontario's decision when the Hydro One CEO and board exit amid share declines. The previous B.C. Liberal government named her president and CEO of B.C. Hydro in 2014, and McDonald was a strong supporter of the controversial Site C dam project now going ahead following a review.

The current New Democratic government placed her on what financial disclosure documents call “salary continuance” effective July 21, 2017 — the day the government announced her departure — at a utility scrutinized in a misled regulator report that raised oversight concerns.

According to financial disclosure statements, McDonald remained on “salary continuance” until Sept. 21 of this year, and the utility has also been assessed in a deferred operating costs report released by the auditor general. During this period, she earned $272,659, a figure that includes benefits, pension and other compensation.

McDonald — who used to be the deputy minister to former premier Gordon Campbell — is now working for Canada Post, which appointed her as interim president and chief executive officer in March, while developments at Manitoba Hydro highlight broader political pressures on Crown utilities.

She started in her new role on April 2, 2018, and now finds herself in the middle of managing a postal carrier strike.

US Electricity Prices Rise Most in 41 Years as Inflation Endures

US Electricity Price Surge drives bills as BLS data show 15.8 percent jump; natural gas and coal costs escalate amid energy crisis, NYISO warns of wholesale prices and winter futures near $200 per MWh.

 

Key Points

A sharp rise in power bills driven by higher natural gas and coal costs and tighter wholesale markets.

✅ BLS reports electricity bills up 15.8% year over year

✅ Natural gas bills up 33% as fuel costs soar

✅ NYISO flags winter wholesale prices near $200/MWh

 

Electricity bills for US consumers jumped the most since 1981, gaining 15.8% from the same period a year ago, according to the US Bureau of Labor Statistics, and residential bills rose 5% in 2022 across the U.S.

Natural gas bills, which crept back up last month after dipping in July, surged 33% from the same month last year, labor data released Tuesday showed, as electricity and natural gas pricing dynamics continue to ripple through markets. Broader energy costs slipped for a second consecutive month because of lower gasoline and fuel oil prices. Even with that drop, total energy costs were still about 24% above August 2021 levels.

Electricity costs are relentlessly climbing because prices for the two biggest power-plant fuels -- natural gas and coal -- have surged in the last year as the US economy rebounds from the pandemic and as Russia’s war in Ukraine triggers an energy crisis in Europe, where German electricity prices nearly doubled over a year. Another factor is the hot and humid summer across most of the lower 48 states drove households and businesses to crank up air conditioners. Americans likely used a record amount of power in the third quarter, according to US Energy Information Administration projections, even as U.S. power demand is seen sliding 1% in 2023 on milder weather.

New York’s state grid operator warned of a “sharp rise in wholesale electric costs expected this winter” with spiking global demand for fossil fuels, lagging supply and instability from Russia’s war in Ukraine driving up oil and gas prices, with multiple energy-crisis impacts on U.S. electricity and gas still unfolding, according to a Tuesday report. Geopolitical factors are ultimately reflected in wholesale electricity prices and supply charges to consumer bills, the New York Independent System Operator said, and as utilities direct more spending to delivery rather than production.

Electricity price futures for this winter have increased fourfold from last year, and potential deep-freeze disruptions to the energy sector could add volatility, with prices averaging near $200 a megawatt-hour, the grid operator said. That has been driven by natural gas futures for the upcoming winter, which are more than double current prices to nearly $20 per million British thermal units.

BMW boss says hydrogen, not electric, will be "hippest thing" to drive

BMW Hydrogen Fuel Cell Strategy positions iX5 and eDrive for zero-emission mobility, leveraging fuel cells, fast refueling, and hydrogen infrastructure as an alternative to BEVs, diversifying drivetrains across premium segments globally, rapidly.

 

Key Points

BMW's plan to commercialize hydrogen fuel-cell drivetrains like iX5 eDrive for scalable, zero-emission mobility.

✅ Fuel cells enable fast refueling and long range with water vapor only.

✅ Reduces reliance on lithium and cobalt via recyclable materials.

✅ Targets premium SUV iX5; limited pilots before broader rollout.

 

BMW is hanging in there with hydrogen, a stance mirrored in power companies' hydrogen outlook today. That’s what Oliver Zipse, the chairperson of BMW, reiterated during an interview last week in Goodwood, England. 

“After the electric car, which has been going on for about 10 years and scaling up rapidly, the next trend will be hydrogen,” he says. “When it’s more scalable, hydrogen will be the hippest thing to drive.”

BMW has dabbled with the idea of using hydrogen for power for years, even though it is obscure and niche compared to the current enthusiasm surrounding vehicles powered by electricity. In 2005, BMW built 100 “Hydrogen 7” vehicles that used the fuel to power their V12 engines. It unveiled the fuel cell iX5 Hydrogen concept car at the International Motor Show Germany in 2021. 

In August, the company started producing fuel-cell systems for a production version of its hydrogen-powered iX5 sport-utility vehicle. Zipse indicated it would be sold in the United States within the next five years, although in a follow-up phone call a spokesperson declined to confirm that point. Bloomberg previously reported that BMW will start delivering fewer than 100 of the iX5 hydrogen vehicles to select partners in Europe, the U.S., and Asia, where Asia leads on hydrogen fuel cells today, from the end of this year.

All told, BMW will eventually offer five different drivetrains to help diversify alternative-fuel options within the group, as hybrids gain renewed momentum in the U.S., Zipse says.

“To say in the U.K. about 2030 or the U.K. and in Europe in 2035, there’s only one drivetrain, that is a dangerous thing,” he says. “For the customers, for the industry, for employment, for the climate, from every angle you look at, that is a dangerous path to go to.” 

Zipse’s hydrogen dreams could even extend to the group’s crown jewel, Rolls-Royce, which BMW has owned since 1998. The “magic carpet ride” driving style that has become Rolls-Royce’s signature selling point is flexible enough to be powered by alternatives to electricity, says Rolls-Royce CEO Torsten Müller-Ötvös. 

“To house, let’s say, fuel cell batteries: Why not? I would not rule that out,” Müller-Ötvös told reporters during a roundtable conversation in Goodwood on the eve of the debut of the company’s first-ever electric vehicle, Spectre. “There is a belief in the group that this is maybe the long-term future.”

Such a vehicle would contain a hydrogen fuel-cell drivetrain combined with BMW’s electric “eDrive” system. It works by converting hydrogen into electricity to reach an electrical output of up to 125 kW/170 horsepower and total system output of nearly 375hp, with water vapor as the only emission, according to the brand.

Hydrogen’s big advantage over electric power, as EVs versus fuel cells debates note, is that it can supply fuel cells stored in carbon-fiber-reinforced plastic tanks. “There will [soon] be markets where you must drive emission-free, but you do not have access to public charging infrastructure,” Zipse says. “You could argue, well you also don’t have access to hydrogen infrastructure, but this is very simple to do: It’s a tank which you put in there like an old [gas] tank, and you recharge it every six months or 12 months.”

Fuel cells at BMW would also help reduce its dependency on raw materials like lithium and cobalt, because the hydrogen-based system uses recyclable components made of aluminum, steel, and platinum. 

Zipse’s continued commitment to prioritizing hydrogen has become an increasingly outlier position in the automotive world. In the last five years, electric-only vehicles have become the dominant alternative fuel — as the age of electric cars dawns ahead of schedule — if not yet on the road, where fewer than 3% of new cars have plugs, at least at car shows and new-car launches.

Rivals Mercedes-Benz and Audi scrapped their own plans to develop fuel cell vehicles and instead have poured tens of billions of dollars into developing pure-electric vehicle, including Daimler's electrification plan initiatives. Porsche went public to finance its own electric aspirations. 

BMW will make half of all new-car sales electric by 2030 across the group, with many expecting most drivers to go electric within a decade, which includes MINI and Rolls-Royce.

Ford's Washington Meeting: Energy Tariffs and Trade Tensions with U.S

Ontario-U.S. Energy Tariff Dispute highlights cross-border trade tensions, retaliatory tariffs, export surcharges, and White House negotiations as Doug Ford meets U.S. officials to de-escalate pressure over steel, aluminum, and energy supplies.

 

Key Points

A trade standoff over energy exports and tariffs, sparked by Ontario's surcharge and U.S. duties on steel and aluminum.

✅ 25% Ontario energy surcharge paused before White House talks

✅ U.S. steel and aluminum tariffs reduced from 50% to 25%

✅ Potential energy supply cutoff remains leverage in negotiations

 

Ontario Premier Doug Ford's recent high-stakes diplomatic trip to Washington, D.C., underscores the delicate trade tensions between Canada and the United States, particularly concerning energy exports and Canada's electricity exports across the border. Ford's potential use of tariffs or even halting U.S. energy supplies, amid Ontario's energy independence considerations, remains a powerful leverage tool, one that could either de-escalate or intensify the ongoing trade conflict between the two neighboring nations.

The meeting in Washington follows a turbulent series of events that began with Ontario's imposition of a 25% surcharge on energy exports to the U.S. This move came in retaliation to what Ontario perceived as unfair treatment in trade agreements, a step that aligned with Canadian support for tariffs at the time. In response, U.S. President Donald Trump's administration threatened its own set of tariffs, specifically targeting Canadian steel and aluminum, which further escalated tensions. U.S. officials labeled Ford's threat to cut off U.S. electricity exports and energy supplies as "egregious and insulting," warning of significant economic retaliation.

However, shortly after these heated exchanges, Trump’s commerce secretary, Howard Lutnick, extended an invitation to Ford for a direct meeting at the White House. Ford described this gesture as an "olive branch," signaling a potential de-escalation of the dispute. In the lead-up to this diplomatic encounter, Ford agreed to pause the energy surcharge, allowing the meeting to proceed, amid concerns tariffs could spike NY energy prices, without further escalating the crisis. Trump's administration responded by lowering its proposed 50% tariff on Canadian steel and aluminum to a more manageable 25%.

The outcome of the meeting, which is set to address these critical issues, could have lasting implications for trade relations between Canada and the U.S. If Ford and Lutnick can reach an agreement, the potential for tariff imposition on energy exports, though experts advise against cutting Quebec's energy exports due to broader risks, could be resolved. However, if the talks fail, it is likely that both countries could face further retaliatory measures, compounding the economic strain on both sides.

As Canada and the U.S. continue to navigate these complex issues, where support for Canadian energy projects has risen, the outcome of Ford's meeting with Lutnick will be closely watched, as it could either defuse the tensions or set the stage for a prolonged trade battle.

Ontario's EV Jobs Boom

Honda Canada EV Supply Chain accelerates electric vehicles with Ontario assembly, battery manufacturing, CAM/pCAM and separator plants in Alliston, creating green jobs, strengthening domestic manufacturing, and reducing greenhouse gas emissions across North America.

 

Key Points

A $15B Ontario initiative for end-to-end EVs, batteries, and components, creating jobs and cutting emissions.

✅ Alliston EV assembly and battery plants anchor production.

✅ CAM/pCAM and separator facilities via POSCO, Asahi JV.

✅ $15B build-out drives jobs, R&D, and lower emissions.

 

The electric vehicle (EV) revolution is gaining momentum in Canada, with Honda Canada announcing a historic $15 billion investment to establish the country's first comprehensive EV supply chain in Ontario. This ambitious project promises to create thousands of new jobs, solidify Canada's position in the EV market, and significantly reduce greenhouse gas emissions.

Honda's Electrifying Vision

The centerpiece of this initiative is a brand-new, world-class electric vehicle assembly plant in Alliston, Ontario. This will be Honda's first dedicated EV assembly plant globally, marking a significant shift towards a more sustainable future. Additionally, a standalone battery manufacturing plant will be constructed at the same location, ensuring a reliable and efficient domestic supply of EV batteries.

Beyond Assembly: A Complete Ecosystem

Honda's vision extends beyond just vehicle assembly. The investment also includes the construction of two additional plants dedicated to critical battery components, mirroring activity such as a Niagara Region battery plant in Ontario: a cathode active material and precursor (CAM/pCAM) processing plant and a separator plant. These facilities, established through joint ventures with POSCO Future M Co., Ltd. and Asahi Kasei Corporation, will ensure a comprehensive in-house EV production capability.

Jobs, Growth, and a Greener Future

This large-scale project is expected to create significant economic benefits for Ontario. The construction and operation of the new facilities are projected to generate over one thousand well-paying manufacturing jobs, similar to GM's Ontario EV plant announcements that underscore employment gains across the province. Additionally, the investment will stimulate growth within Ontario's leading auto parts supplier and research and development ecosystems, bolstered by government-backed EV plant upgrades that reinforce local supply chains, creating even more indirect job opportunities.

But the benefits extend beyond the economy. The transition to electric vehicles plays a crucial role in combating climate change. By bringing EV production onshore, Honda Canada is contributing to a significant reduction in greenhouse gas emissions, aligning with Canada's ambitious climate goals for transportation.

A Catalyst for Change

Honda's investment is a significant vote of confidence in Canada's potential as a leader in the EV industry, as recent EV manufacturing deals put the country in the race. The establishment of this comprehensive EV supply chain will not only benefit Honda, but also attract other EV manufacturers and solidify Ontario's position as a North American EV hub.

The road ahead for Canada's EV industry is bright. With Honda's commitment and this groundbreaking project, and with Ford's Oakville EV plans underway, Canada is well on its way to a cleaner, more sustainable future powered by electric vehicles.

Green energy could drive Covid-19 recovery with $100tn boost

Renewable Energy Economic Recovery drives GDP gains, job growth, and climate targets by accelerating clean energy investment, green hydrogen, and grid modernization, delivering high ROI and a resilient, low-carbon transition through stimulus and policy alignment.

 

Key Points

A strategy to boost GDP and jobs by accelerating clean power and green hydrogen while meeting climate goals.

✅ Adds $98tn to global GDP by 2050; $3-$8 return per $1 invested

✅ Quadruples clean energy jobs to 42m; improves health and welfare

✅ Cuts CO2 70% by 2050; enables net-zero via green hydrogen

 

Renewable energy could power an economic recovery from Covid-19 through a green recovery that spurs global GDP gains of almost $100tn (£80tn) between now and 2050, according to a report.

The International Renewable Energy Agency’s new IRENA report found that accelerating investment in renewable energy could generate huge economic benefits while helping to tackle the global climate emergency.

The agency’s director general, Francesco La Camera, said the global crisis ignited by the coronavirus outbreak exposed “the deep vulnerabilities of the current system” and urged governments to invest in renewable energy to kickstart economic growth and help meet climate targets.

The agency’s landmark report found that accelerating investment in renewable energy would help tackle the climate crisis and would in effect pay for itself.

Investing in renewable energy would deliver global GDP gains of $98tn above a business-as-usual scenario by 2050, as clean energy investment significantly outpaces fossil fuels, by returning between $3 and $8 on every dollar invested.

It would also quadruple the number of jobs in the sector to 42m over the next 30 years, and measurably improve global health and welfare scores, according to the report.

“Governments are facing a difficult task of bringing the health emergency under control while introducing major stimulus and recovery measures, as a US power coalition demands action,” La Camera said. “By accelerating renewables and making the energy transition an integral part of the wider recovery, governments can achieve multiple economic and social objectives in the pursuit of a resilient future that leaves nobody behind.”

The report also found that renewable energy could curb the rise in global temperatures by helping to reduce the energy industry’s carbon dioxide emissions by 70% by 2050 by replacing fossil fuels, with measures like a fossil fuel lockdown hastening the shift.

Renewables could play a greater role in cutting carbon emissions from heavy industry and transport to reach virtually zero emissions by 2050, particularly by investing in green hydrogen.

The clean-burning fuel, which can replace the fossil fuel gas in steel and cement making, could be made by using vast amounts of clean electricity to split water into hydrogen and oxygen elements.

Andrew Steer, chief executive of the World Resources Institute, said: “As the world looks to recover from the current health and economic crises, we face a choice: we can pursue a modern, clean, healthy energy system, or we can go back to the old, polluting ways of doing business. We must choose the former.”

The call for a green economic recovery from the coronavirus crisis comes after a warning from Dr Fatih Birol, head of the International Energy Agency, that government policies must be put in place to avoid an investment hiatus in the energy transition, even as the solar and wind industry faces Covid-19 disruptions.

“We should not allow today’s crisis to compromise the clean energy transition, even as wind power growth persists despite Covid-19,” he said. “We have an important window of opportunity.”

Ignacio Galán, the chairman and CEO of the Spanish renewables giant Iberdrola, which owns Scottish Power, said the company would continue to invest billions in renewable energy as well as electricity networks and batteries to help integrate clean energy in the electricity.

“A green recovery is essential as we emerge from the Covid-19 crisis. The world will benefit economically, environmentally and socially by focusing on clean energy,” he said. “Aligning economic stimulus and policy packages with climate goals is crucial for a long-term viable and healthy economy.”
