Fire officials say a powerful electricity surge that followed a four-hour blackout in Guyana's capital may have caused a fire that killed two children in their home.

Fire Department commanders say they don't know the precise cause of the early Easter blaze in the working-class Wortmanville section of the capital, Georgetown. But they say it's possible the surge may have sparked faulty wiring at the wooden home, where a 14-month-old boy and his 3-year-old brother were killed.

Residents of Georgetown have frequently complained about hazardous surges during rolling blackouts.

Yukon eyes connection to B.C. electricity grid

Yukon-BC Electricity Intertie could link Yukon to BC's hydroelectric power, enabling renewable energy integration, net-zero grid goals by 2035, transmission expansion for mining, and stronger Arctic energy security through a coast-to-coast network.

 

Key Points

A link connecting Yukon's grid to BC hydro to import renewables, cut emissions, and strengthen northern energy security.

✅ Enables renewable imports to meet 2035 net-zero electricity target

✅ Supports mining growth with reliable, low-carbon power

✅ Enhances Arctic energy security via national grid integration

 

Yukon's energy minister says Canada's push for more green energy and a net-zero electricity grid should spark renewed interest in connecting the territory's power to British Columbia, home to the Electric Highway network.

Minister of Energy, Mines and Resources John Streicker says linking the territory's power grid to the south would help with the national move to renewable energy, including new wind turbines being added in the Yukon, support the mineral extraction required for green projects, and improve northern energy and Arctic security.

"We're getting to the moment in time when we will want an electricity grid which stretches from coast to coast to coast. … I think that the moment is coming for this — it's sort of a nation-building moment. And I think that from the Yukon's perspective, we're very interested," Streicker said in an interview.

The idea of a link, originally proposed to span 763 kilometres between Whitehorse and Iskut, B.C., was first floated in 2016 but sat on the shelf after a viability study put the price tag at as much as $1.7 billion, even as a study indicates B.C. may need to double its power output to electrify all road vehicles.


Two years later, Yukon's then-energy-minister Ranj Pillai — now premier — mused again about the possibility of connecting to power from B.C., where green energy ambitions include the Site C hydro dam.

The idea appeared to have been resurrected at this year's Western Premiers' Conference in June, with both Pillai and B.C. Premier David Eby publicly mentioning early conversations about grid development and interties.

At the conference, Eby said British Columbia was fortunate to have the ability to support other jurisdictions with its hydro electricity.

"So certainly part of the conversation was how do we support each other in sharing our strength, including emerging hydrogen projects across the province?" he said.

"And one of those that British Columbia was able to put on the table is if we can find ways to enter ties with, for example, with the Yukon, to support them in their efforts to access more electricity to grow their economy and decarbonize their electrical grid, then that's very good news for everybody."

The federal government has set a target of making the country's electricity grid net-zero by 2035, while jurisdictions like the N.W.T. plan for more residents to drive electric vehicles as part of the transition.

N.W.T. green energy advocate urges using more electricity for heat

Taltson Hydro Electric Heating directs surplus hydro power in the South Slave to space heat via discounted rates, displacing diesel and cutting greenhouse gas emissions, with rebates, separate metering, and backup systems shaping adoption.

 

Key Points

An initiative using Taltson's surplus hydro to heat buildings, discount rates replace diesel and cut emissions.

✅ 6.3 cents/kWh heating rate needs separate metering, backup heat

✅ 4-6 MW surplus hydro; outages require diesel; rebates available

✅ Program may be curtailed if new mines or mills demand power

 

A Northwest Territories green energy advocate says there's an obvious way to expand demand for electricity in the territory's South Slave region without relying on new mining developments — direct it toward heating.

One of the reasons the N.W.T. has always had some of the highest electricity rates in Canada is that a small number of people have to shoulder the huge costs of hydro facilities and power plants.

But some observers point out that residents consume as much energy for heat as they do for conventional uses of electricity, such as lighting and powering appliances. Right now almost all of that heat is generated by expensive oil imported from the United States.

The Northwest Territories Power Corporation says the 18-megawatt Taltson hydro system that serves the South Slave typically has four to six megawatts of excess generating capacity, even as record demand in Yukon is reported. It says using some of that to generate heat is a government priority.

But renewable energy advocate and former N.W.T. MP Dennis Bevington, who lives in the South Slave and heats his home using electricity, says the government is not making it easy for people to tap into that surplus to heat their homes and businesses, a debate that some say would benefit from independent planning at the national level.

Discount rate for heating, but there are catches
The power corporation offers hydro electricity from Taltson to use for heating at a much lower price than it charges for electricity generally. The discounted rate is not available to residential customers.

According to the corporation, consumers pay only 6.3 cents per kilowatt hour compared to the regular rate of just under 24 cents, while Manitoba Hydro financial pressures highlight the risks of expanding demand without new generation.

But to distinguish between the two, users are required to cover the cost of installing a separate power meter. Bevington, who developed the N.W.T.'s first energy strategy, says that is an unnecessary expense.

Taltson expansion key to reducing N.W.T.'s greenhouse gas emissions, says gov't
"The billing is how you control that," he said. "You establish an average electrical use in the winter months. That could be the base rate. Then, if you use power in the winter months above that, you get the discount."

Users are also required to have a back-up heating system. Taltson hydro power offers heating on the understanding that when the hydro system is down — such as during power outages or annual summer maintenance of the hydro system — electricity is not available for heating.
The president and CEO of the power corporation says there's a good reason for that. "The diesels are more expensive to run and they're actually greenhouse gas emitting," said Noel Voykin. "The whole idea of this [electric heat] program is to provide clean energy that is not otherwise being used."

According to the corporation, there have been huge savings for the few who have tapped into the hydro system to heat their buildings, and across Canada utilities are exploring novel generation such as NB Power's Belledune seawater project to diversify supply.

It's being used to heat Aurora College's Breynat Hall, and Joseph B. Tyrrell Elementary School and the transportation department garage in Fort Smith, N.W.T. Electricity is also used to heat the Jackfish power plant in the North Slave region.

The corporation says that during a four-year period, this saved more than 600,000 litres of diesel fuel and reduced greenhouse gas emissions by about 1,700 tonnes.

Bevington says the most obvious place to expand the use of electrical heat is to government housing.

"We have a hundred public housing units in Fort Smith," he said. "The government is putting diesel into those units [for heating] and they could be putting in their own electricity."

Heating a tiny part of energy market
The corporation says it sells only about 2.5 megawatts of electricity for heating each year, which is less than four per cent of the power it sells in the region. It says with some upgrades, another two megawatts of electricity could be made available for electrical heat.

Bevington says the corporation could do more to market electricity for heating. Voykin said that's the government's job. There are three programs that offer rebates to residents and businesses converting to electric heating.

If you build it, will they come? N.W.T. gov't hopes hydro expansion will attract investment
There are better options than billion dollar Taltson expansion, say energy leaders
There may be a reason why the government and the corporation are not more aggressively promoting using surplus electricity in the Taltson system for heating, as large hydro ambitions have reopened old wounds in places like Quebec and Newfoundland and Labrador during recent debates.

It is anticipating that new industrial customers may require that excess capacity in the coming years, and experiences elsewhere show that accommodating new energy-intensive customers can be challenging for utilities. Voykin said those potential new customers include a proposed mine at Pine Point and a pellet mill in Enterprise, N.W.T., even as biomass use faces environmental pushback in some regions.

The corporation says any surplus power in the system will be sold at standard rates to any new industrial customers instead of at discount rates for heating. If that requires cutting back on the heating program, it will be cut back.

Ottawa won't oppose halt to Site C work pending treaty rights challenge

Site C Dam Injunction signals Ottawa's neutrality while B.C. reviews a hydroelectric dam project on the Peace River, amid First Nations treaty rights claims, federal approval defenses, and scrutiny of environmental assessment and Crown consultation.

 

Key Points

A legal request to pause Site C while courts weigh First Nations treaty rights, environmental review, and approvals.

✅ Ottawa neutral on injunction; still defends federal approvals

✅ First Nations cite treaty rights over Peace River territory

✅ B.C. jurisdiction, environmental assessment and Crown consultation at issue

 

The federal government is not going to argue against halting construction of the controversial Site C hydroelectric dam in British Columbia while a B.C. court decides if the project violates constitutionally protected treaty rights.

 

Work on Site C suspended prior to First Nations lawsuit

However a spokeswoman for Environment Minister Catherine McKenna said Monday the government will continue to defend the federal approval given for the project in December 2014, even though that approval was given using an environmental review process McKenna herself has said is fundamentally flawed.

The Site C project is an 1,100-megawatt dam and generating station on the Peace River in northern B.C. that will flood parts of the traditional territory of the West Moberly and Prophet River First Nations.

#google#

In January, they filed a civil court case against the provincial government, B.C. Hydro and the federal government asking a judge to decide if their rights were being violated by the dam. A few weeks later, West Moberly asked the court for an injunction to halt construction pending the outcome of the rights case, similar to other contested transmission projects like the Maine electricity corridor debate in New England.

On May 11, lawyers for Attorney General Jody Wilson-Raybould filed a notice that Canada would remain neutral on the question of the injunction, meaning Canada won't argue against the idea of postponing construction for months, if not years, while the rights case winds through the court.

Wilson-Raybould has been silent on Site C since being named Canada's minister of justice in 2015, but in 2012, when she was the B.C. regional chief for the Assembly of First Nations, she said the project was "running roughshod" over treaty rights. The Justice Department on Monday directed questions to Environment and Climate Change Canada.

 

Defence of environmental assessment

McKenna's spokeswoman, Caroline Theriault, said the injunction request is just a procedural step regarding construction and that it is B.C. jurisdiction not federal.

However, she said Canada will defend the environmental assessment and Crown consultation processes and the federally issued permits required for construction.

 

B.C. auditor general set to scrutinize Site C dam project

McKenna has legislation before the House of Commons to overhaul the process for environmental assessment of major projects like hydro dams and pipelines, arguing the former government's procedures had skewed too far towards proponents. The overhaul includes requiring traditional Indigenous knowledge be taken into account, a consideration also central to the Columbia River Treaty talks underway on both sides of the border.

However, Theriault said the commitment to overhaul the process also included a promise not to revisit projects that had already been approved, such as Site C.

"The federal environmental assessment process for the Site C project has already been upheld in other court actions," said Theriault.

 

'It feels kind of odd'

West Moberly Chief Roland Wilson said he was both excited and yet concerned by Canada's decision last week not to oppose the injunction.

"It feels kind of odd and makes me wonder what they're up to," Wilson said.

However he said all he has ever wanted was for the project to be stopped until the question of rights can be answered. Wilson said two previous dams on the Peace River already flooded 80 per cent of the functional land within West Moberly's territory and that Site C will flood half of what's left. That land is used for fishing and hunting and there is also concern the dam will allow mercury to leak into Moberly Lake, he said.

 

Retiree undaunted by steep odds against his petition to stop Site C dam

Construction began in 2015 and more than $2.4 billion has already been spent on a project that will at the earliest, not be completed until 2024 and will cost an estimated $10 billion total, with cost overrun risks underscored by the Muskrat Falls ratepayer agreement in Atlantic Canada.

The province continues to argue against the injunction and will also fight the rights case, even as Alberta suspends power purchase talks with B.C. over energy disputes. Premier John Horgan campaigned on a promise to review the Site C approval. A B.C. Utilities Commission report in November found there are alternatives to building it and that it will go over budget. Nevertheless Horgan in December said he had to let construction continue because cancelling the project would be too costly both for the province and its electricity consumers, despite the B.C. rate freeze announced around the same period.

New fuel cell could help fix the renewable energy storage problem

Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

 

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

 

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

Electrifying: New cement makes concrete generate electricity

Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

 

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

 

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”

New York Finalizes Contracts for 23 Renewable Projects Totaling 2.3 GW

New York Renewable Energy Contracts secure 23 projects totaling 2.3 GW, spanning offshore wind, solar, and battery storage under CLCPA goals, advancing 70% by 2030, a carbon-free 2040 grid, grid reliability, and green jobs.

 

Key Points

State agreements securing 23 wind, solar, and storage projects (2.3 GW) to meet CLCPA clean power targets.

✅ 2.3 GW across 23 wind, solar, and storage projects statewide

✅ Supports 70% renewables by 2030; carbon-free grid by 2040

✅ Drives emissions cuts, grid reliability, and green jobs

 

In a significant milestone for the state’s clean energy ambitions, New York has finalized contracts with 23 renewable energy projects, as part of large-scale energy projects underway in New York, totaling a combined capacity of 2.3 gigawatts (GW). This move is part of the state’s ongoing efforts to accelerate its transition to renewable energy, reduce carbon emissions, and meet the ambitious targets set under the Climate Leadership and Community Protection Act (CLCPA), which aims to achieve a carbon-free electricity grid by 2040.

A Strong Commitment to Renewable Energy

The 23 projects secured under these contracts represent a diverse range of renewable energy sources, including wind, solar, and battery storage. Together, these projects are expected to contribute significantly to New York’s energy grid, generating enough clean electricity to power millions of homes. The deal is a key component of New York’s broader strategy to achieve a 70% renewable energy share in the state’s electricity mix by 2030 and to reduce greenhouse gas emissions by 85% by 2050.

Governor Kathy Hochul celebrated the agreements as a major step forward in the state’s commitment to combating climate change while creating green jobs and economic opportunities. “New York is leading the nation in its clean energy goals, and these projects will help us meet our bold climate targets while delivering reliable and affordable energy to New Yorkers,” Hochul said in a statement.

The Details of the Contracts

The 23 projects span across various regions of the state, with an emphasis on areas that are well-suited for renewable energy development, such as upstate New York, which boasts vast open spaces ideal for large-scale solar and wind installations and the state is investigating sites for offshore wind projects along the coast. The contracts finalized by the state will ensure a steady supply of clean power from these renewable sources, helping to stabilize the grid and reduce reliance on fossil fuels.

A significant portion of the new renewable capacity will come from offshore wind projects, which have become a cornerstone of New York’s renewable energy strategy. Offshore wind has the potential to provide large amounts of electricity, and the state recently greenlighted the country's biggest offshore wind farm to date, taking advantage of the state's proximity to the Atlantic Ocean. Several of the contracts finalized include offshore wind farm projects, which are expected to be operational within the next few years.

In addition to wind energy, solar power continues to be a critical component of the state’s renewable energy strategy. The state has already made substantial investments in solar energy, having achieved solar energy goals ahead of schedule recently, and these new contracts will further expand the state’s solar capacity. The inclusion of battery storage projects is another important element, as energy storage solutions are vital to ensuring that renewable energy can be effectively utilized, even when the sun isn’t shining or the wind isn’t blowing.

Economic and Job Creation Benefits

The finalization of these 23 contracts will not only bring significant environmental benefits but also create thousands of jobs in the renewable energy sector. Construction, maintenance, and operational jobs will be generated throughout the life of the projects, benefiting communities across the state, including areas near Long Island's South Shore wind proposals that stand to gain from new investment. The investment in renewable energy is expected to support New York’s recovery from the economic impacts of the COVID-19 pandemic, contributing to the state’s clean energy economy and providing long-term economic stability.

The state's focus on clean energy also provides opportunities for local businesses, highlighted by the first Clean Energy Community designation in the state, as many of these projects will require services and materials from within New York State. Additionally, Governor Hochul’s administration has made efforts to ensure that disadvantaged communities and workers from underrepresented backgrounds will have access to job training and employment opportunities within the renewable energy sector.

The Path Forward: A Clean Energy Future

New York’s aggressive move toward renewable energy is indicative of the state’s commitment to addressing climate change and leading the nation in clean energy innovation. By locking in contracts for these renewable energy projects, the state is not only securing a cleaner future but also ensuring that the transition is fair and just for all communities, particularly those that have been historically impacted by pollution and environmental degradation.

While the finalized contracts mark a major achievement, the state’s work is far from over. The completion of these 23 projects is just one piece of the puzzle in New York’s broader strategy to decarbonize its energy system. To meet its ambitious targets under the CLCPA, New York will need to continue investing in renewable energy, energy storage, grid modernization, and energy efficiency programs.

As New York moves forward with its clean energy transition, and as BOEM receives wind power lease requests in the Northeast, the state will likely continue to explore new technologies and innovative solutions to meet the growing demand for renewable energy. The success of the 23 finalized contracts serves as a reminder of the state’s leadership in the clean energy space and its ongoing efforts to create a sustainable, low-carbon future for all New Yorkers.

New York’s decision to finalize contracts with 23 renewable energy projects totaling 2.3 gigawatts represents a bold step toward meeting the state’s clean energy and climate goals. These projects, which include a mix of wind, solar, and energy storage, will contribute significantly to reducing the state’s reliance on fossil fuels and lowering greenhouse gas emissions. With the additional benefits of job creation and economic growth, this move positions New York as a leader in the nation’s transition to renewable energy and a sustainable future.
