Middle Georgia could be home to the state's first new coal-fired power plant in two decades if state environmental officials approve a $2.1 billion project in Washington County.

In January, POWER4Georgians, a consortium of 10 electric cooperatives, applied for environmental permits to build and operate the proposed Plant Washington. It would generate about 850 megawatts of power a day on a 1,200-acre site about eight miles north of Sandersville.

Another new coal-fired power plant is also planned west of Albany by a different company, but that project is mired in court. As coal-fired power faces increasing opposition for its contributions to smog, soot and global warming, the Plant Washington proposal is being fought by environmental groups.

"I can't even tell you how it took the breath out of me to hear they were looking to build a new coal plant on the Oconee River," said Deborah Sheppard, executive director of the Altamaha Riverkeeper group.

"As long as our state and country continue to eek electricity through new plants, it will only increase the demand for more new plants, and that will only increase stresses on our water and air."

Sandersville Mayor Jimmy Evans said locals have questioned the effect of truck and rail traffic on neighbors and impacts to the groundwater table, but they seem to generally support the effort.

The plant, to be located on former farmland with few immediate neighbors, will bring about130 permanent jobs and a substantial but as-yet-undetermined boost to the county tax base. Local electricity provider Washington EMC is one of the 10 cooperatives that teamed to create POWER4Georgians, which would own the plant.

The cooperatives would sell the electricity. Other Middle Georgia partners include Central Georgia EMC and Upson EMC.

But some of the biggest players, such as Cobb EMC, are in fast-growing areas outside the region. POWER4Georgians maintains that without the plant, customers would soon have to pay perhaps twice as much for electricity, and the state would experience power shortages.

Most of the cooperatives had contracts with private utilities such as Georgia Power to provide some of their electricity. These contracts are expiring soon and cannot be renewed at affordable prices, said Dean Alford, whose Conyers company, Allied Energ Services, is the primary developer of the plant.

Oglethorpe Power was created by the state's electricity cooperatives in 1974 to deal with the same problem. But Oglethorpe has its plate full with the effort to add two nuclear reactors to Plant Vogtle, a joint project with Georgia Power and others.

Alford said some cooperatives can't wait.

By 2015, Alford said, growing population will mean the partners in POWER4Georgians need one-third more base power capacity than they have now. Critics say power companies should focus on energy efficiency and developing "green" power sources such as solar energy.

Alford said POWER4Georgians is involved in both these efforts, but "there's just no way around needing new generation."

POWER4Georgians needs at least six environmental permits for the plant: an air pollution permit, groundwater and surface water withdrawal permits, a water discharge permit for used water that goes back into the Oconee River, a permit for the storm water running off from the plant, and a permit for storing the solid waste such as gypsum and fly ash generated by the plant.

The state Environmental Protection Division is talking with the company and its experts. After satisfying any concerns, the EPD would then issue draft permits and let people comment on them. Public meetings and hearings must be held during this process.

Jack Capp, permitting manager for the EPD's air branch, said draft permits could be issued by the end of the year. Plant developers already held a public meeting in Sandersville days after filing the permit applications, and Alford has been meeting with community groups since then, he said.

New power plants are required to install the "best available pollution control technology" to limit air pollution.

Plant Washington is proposed to be the first in the state installed with wet scrubbers and other advances.

Power plants are some of the biggest contributors to ground-level ozone, the primary component of smog, and to fine particle pollution, such as soot that can be absorbed deep in the lungs. Both types cause heart and lung problems.

Macon is in a federal nonattainment zone for having dangerous levels of fine particle pollution, and it is expected to fall back into nonattainment for its ozone pollution under new federal rules. (Athens and Augusta, also not far from Sandersville, are also expected to fail the new ozone standard.) Scientists and regulators have identified Georgia Power's nearby Plant Scherer, the largest coal-fired power plant in the country, as one of the prime culprits for Macon's air pollution.

Washington County and neighboring Wilkinson County already struggle with unsafe levels of fine particle pollution. They have not yet been designated a nonattainment zone, but without improvements they probably will be, state regulators have said.

Evans said he feels comfortable that the new coal-fired plant won't put the county in jeopardy for nonattainment.

Alford said the plant is being designed to release zero measurable fine particles, and its technology will make ozone contributions far less than those of nearby power plants like Scherer. Capp said the EPD can't approve the plant if it will cause or contribute to violations of a national air standard.

That means it can't diminish a county's air quality enough to put the area in a nonattainment zone, and it can't contribute significantly to air pollution in an existing nonattainment area. However, there is a threshold for allowing some additional pollution, he said.

POWER4Georgians must provide computer modeling showing the effect of its air pollution on a broad area, and the state will do some of its own modeling, Capp said. The company has not yet specifically addressed its effects on Macon's air quality, Capp said. Alford said POWER4Georgians is not proposing a larger plant because that would require much more work to reduce harm to air and water.

"And I can assure you this will not be expanded in the future," he said.

Coal-fired power plants also emit mercury, which eventually accumulates in fish tissue. As a neurotoxin, mercury can damage fetuses and cause developmental problems in children.

Chandra Brown, the Ogeechee Riverkeeper, said the state already warns the public to limit consumption of fish from the Ogeechee River because of its mercury levels. "Any addition of mercury is just unacceptable," she said.

Like all coal-fired power plants, Plant Washington would use large amounts of water for its cooling towers. But POWER4Georgians' plan is unusual for its partial reliance on groundwater, as well as a 30-mile pipeline from the plant to its primary water source.

The plant is requesting to use 16 million gallons of water a day from the Oconee River.

Alford said the distance prevents any harm to wetlands and puts it near a major electricity transmission line.

Sheppard, with the Altamaha Riverkeeper, said the Oconee River already is under major stress from development in the Athens area, and it receives significant industrial pollution downstream. The less water in the river, the less there is to dilute the pollution.

"Is it fair to be using water in the Oconee to create energy for north Cobb County?" Sheppard asked. "There's serious equity issues here." However, Alford noted that at least all the power generated by Plant Washington would be used in Georgia - unlike power from some of the larger Georgia Power plants or the other proposed new coal-fired plant, Plant Longleaf.

During times when the Oconee River is low, POWER4Georgians wants approval to withdraw 16 million gallons a day from 16 ground water wells. Wells would be located at intervals along the plant's pipeline to the river and would tap into the Cretaceous aquifer, Alford said.

Having multiple wells reduces the impact on the water table at each site, said Bill Frechette, coordinator for the EPD groundwater permitting unit. All public water systems in Washington County - including the more than 6,000 households in Sandersville - rely on the same aquifer, and rural residents get their water from private wells, Evans said.

But he said the area has not experienced water shortages during the current drought.

"It's true the aquifer contains a lot of water," Frechette said. "On the other hand, there are a significant amount of users in Washington and Wilkinson counties and also the kaolin operations. We will be concerned about impacts on other users."

Alford said Plant Washington would probably rely on groundwater 40 percent of the time. He said the company's analysis shows this would have a negligible effect on the water table - but if anyone's well went dry, POWER4Georgians would replace it.

Frechette said that if the groundwater permit is granted, the plant will easily be among the top 25 groundwater users out of the 475 permitted in the state.

Alford said the company will augment its water supply by reusing storm water at the plant and reclaiming 4 million to 6 million gallons of water a day from local kaolin mines.

Brown praised the effort to use kaolin wastewater but voiced some questions about its effects. She noted that the state doesn't regulate the use of water in kaolin mining.

"We don't know anything about how much there is being used and what the impacts would be on the streams if that water goes somewhere else," she said. Alford said POWER4Georgians has been monitoring kaolin water use for almost a year to determine how much would be available for the power plant.

He declined to say which kaolin companies have been involved. The plant would return a million to 4 million gallons of water to the Oconee River daily, Alford said.

The EPD has already received comments from some groups about the proposed plants, most of them urging denial of the permits. Rick and Jennifer Johnson, Washington County property owners who live in Big Canoe, in north Georgia, wrote that "Washington County does not need a new source of air pollution.... We do not need another contributor to asthma cases, chronic bronchitis a d other health problems."

Greenlaw, a firm of environmental advocacy lawyers, filed comments on behalf of 15 environmental organizations, saying POWER4Georgians has failed to sufficiently analyze the health risks of the plant.

"It's the worst modeling our experts have ever seen," said Justine Thompson, executive director of Greenlaw. Greenlaw also has appealed permits for the proposed Plant Longleaf.

Some environmental groups contend that the state also should limit the amount of carbon dioxide released by the new plant. The federal government doesn't regulate carbon dioxide, the primary "greenhouse gas" responsible for global warming, although Congress is now debating legislation that would change that. Thompson said if both Plant Washington and Plant Longleaf are approved by the state, they will contribute carbon dioxide equivalent to driving 2.5 million new cars about 12,000 miles annually.

According to the POWER4Georgians Web site, Plant Washington will require less than two-thirds the amount of coal and emit less than two-thirds the amount of carbon dioxide as traditional coal-fired power plants.

UK to End Coal Power After 142 Years

UK Coal Phase-Out signals an energy transition, accelerating decarbonization with offshore wind, solar, and storage, advancing net-zero targets, cleaner air, and a just transition for communities impacted by fossil fuel decline.

 

Key Points

A policy to end coal power in the UK, boosting renewables and net-zero goals while improving air quality.

✅ Coal electricity fell from 40% in 2012 to under 3% by 2022

✅ Offshore wind and solar expand capacity; storage enhances reliability

✅ Just transition funds retrain workers and support coal regions

 

The United Kingdom is poised to mark a significant milestone in its energy history by phasing out coal power entirely, ending a reliance that has lasted for 142 years. This decision underscores the UK’s commitment to combating climate change and transitioning toward cleaner energy sources, reflecting a broader global energy transition away from fossil fuels. As the country embarks on this journey, it highlights both the achievements and challenges of moving towards a sustainable energy future.

A Historic Transition

The UK’s relationship with coal dates back to the Industrial Revolution, when coal was the backbone of its energy supply, driving factories, trains, and homes. However, as concerns over air quality and climate change have mounted, the nation has progressively shifted its focus toward renewable energy sources amid a global decline in coal-fired electricity worldwide. The decision to end coal power represents the culmination of this transformation, signaling a definitive break from a past heavily reliant on fossil fuels.

In recent years, the UK has made remarkable strides in reducing its carbon emissions. From 2012 to 2022, coal's contribution to the country's electricity generation plummeted from around 40% to less than 3%, as policies like the British carbon tax took effect across the power sector. This dramatic decline is largely due to the rise of renewable energy sources, such as wind, solar, and hydroelectric power, which have increasingly filled the gap left by coal.

Environmental and Health Benefits

The move away from coal power has significant environmental benefits. Coal is one of the most carbon-intensive energy sources, releasing substantial amounts of carbon dioxide (CO2) and other harmful pollutants into the atmosphere. By phasing out coal, the UK aims to significantly reduce its greenhouse gas emissions and improve air quality, which has been linked to serious health issues such as respiratory diseases and cardiovascular problems.

The UK government has set ambitious net zero policies, aiming to achieve net-zero carbon emissions by 2050. Ending coal power is a critical step in reaching this target, demonstrating leadership on the global stage and setting an example for other countries still dependent on fossil fuels. This transition not only addresses climate change but also promotes a healthier environment for future generations.

The Role of Renewable Energy

As the UK phases out coal, renewable energy sources are expected to play a central role in meeting the country's energy needs. Wind power, in particular, has surged in prominence, with the UK leading the world in offshore wind capacity. In 2020, wind energy surpassed coal for the first time, accounting for over 24% of the country's electricity generation.

Solar energy has also seen significant growth, contributing to the diversification of the UK’s energy mix. The government’s investments in renewable energy infrastructure and technology have facilitated this rapid transition, providing the necessary framework for a sustainable energy future.

Economic Implications

While the transition away from coal power presents environmental benefits, it also carries economic implications. The coal industry has historically provided jobs and economic activity, particularly in regions where coal mining was a mainstay, a dynamic echoed in analyses of the decarbonization of Canada's electricity grid and its regional impacts. As the UK moves toward a greener economy, there is an urgent need to support communities that may be adversely affected by this transition.

To address potential job losses, the government has emphasized the importance of investing in retraining programs and creating new opportunities in the renewable energy sector. This will be vital in ensuring a just transition that supports workers and communities as the energy landscape evolves.

Challenges Ahead

Despite the progress made, the journey toward a coal-free UK is not without challenges. One significant concern is the need for reliable energy storage solutions to complement intermittent renewable sources like wind and solar. Ensuring a stable energy supply during periods of low generation will be critical for maintaining grid reliability.

Moreover, public acceptance and engagement will be crucial, as illustrated by debates over New Zealand's electricity transition and its pace, as the UK navigates this transition. Engaging communities in discussions about energy policies and developments can foster understanding and support for the changes ahead.

Looking to the Future

The UK’s decision to phase out coal power after 142 years marks a significant turning point in its energy policy and environmental strategy. This historic shift not only aligns with the country’s climate goals but also showcases its commitment to a cleaner, more sustainable future.

As the UK continues to invest in renewable energy and transition away from fossil fuels, it sets an important example for other nations, including those on China's path to carbon neutrality, grappling with similar challenges. By embracing this transition, the UK is not only addressing pressing environmental concerns but also paving the way for a greener economy that can thrive in the decades to come.

Britain Goes Full Week Without Coal Power

Britain Coal-Free Week signals a historic shift to clean energy, with zero coal power, increased natural gas and renewables, lower greenhouse gas emissions, and ambitious UK energy policy targeting a 2025 coal phase-out and decarbonization.

 

Key Points

A seven-day period with no coal power in the UK, signaling cleaner energy and progress on emission reductions.

✅ Seven days of zero coal generation in the UK

✅ Natural gas and renewables dominated the electricity mix

✅ Coal phase-out targeted by 2025; emissions cuts planned

 

For the first time in a century, Britain weaned itself off of coal consumption for an entire week, a coal-free power record for the country.

Reuters reported that Britain went seven days without relying on any power generated by coal-powered stations as the share of coal in the grid continued to hit record lows.

The accomplishment is symbolic of a shift to more clean energy sources, with wind surpassing coal in 2016 and the UK leading the G20 in wind share as of recent years; Britain was home to the first coal-powered plant back in the 1880s.

Today, Britain has some aggressive plans in place to completely eliminate its coal power generation permanently by 2025, with a plan to end coal power underway. In addition, Britain aims to cut its total greenhouse gas emissions by 80 percent from 1990 levels within the next 30 years.

Natural gas was the largest source of power for Britain in 2018, providing 39 percent of the nation's total electricity, as the Great Britain generation dashboard shows. Coal contributed only about 5 percent, though low-carbon generation stalled in 2019 according to reports. Burning natural gas also produces greenhouse gases, but it is much more efficient and greener than coal.

In the U.S., 63.5 percent of electricity generated in 2018 came from fossil fuels. About 35.1 percent was produced from natural gas and 27.4 percent came from coal. In addition, 19.3 percent of electricity came from nuclear power and 17.1 percent came from renewable energy sources, according to the U.S. Energy Information Administration.

Beating Covid Is All About Electricity

Hospital Electricity Reliability underpins ICU operations, ventilators, medical devices, and diagnostics, reducing power outages risks via grid power and backup generators, while energy poverty and blackouts magnify COVID-19 mortality in vulnerable regions.

 

Key Points

Hospital electricity reliability is steady power that keeps ICU care, ventilators and medical devices operating.

✅ ICU loads: ventilators, monitors, infusion pumps, diagnostics

✅ Grid power plus backup generators minimize outage risk

✅ Energy poverty increases COVID-19 mortality and infection

 

Robert Bryce, Contributor

During her three-year career as a registered nurse, my friend, C., has cared for tuberculosis patients as well as ones with severe respiratory problems. She’s now caring for COVID-19 patients at a hospital in Ventura County, California, where debates about keeping the lights on continue amid the state’s energy transition. Is she scared about catching the virus? “No,” she replied during a phone call on Thursday. “I’m pretty unflappable.”

What would scare her? She quickly replied, “a power outage,” a threat that grows during summer blackouts when heat waves drive demand. About a year ago, while working in Oregon, the hospital she was working in lost power for about 45 minutes. “It was terrifying,” she said. 

C., who wasn’t authorized by her hospital to talk to the media, and thus asked me to only use the initial of her first name, said that COVID-19 patients are particularly reliant on electrical devices. She quickly ticked off the machines: “The bed, the IV machine, vital signs monitor, heart monitor, the sequential compression devices...” COVID-19 patients are hooked up to a minimum of five electrical devices, she said, and if the virus-stricken patient needs high-pressure oxygen or a ventilator, the number of electrical devices could be two or three times that number. “You name it, it plugs in,” she said.  

Today In: Energy

The virus has infected some 2.2 million people around the world and killed more than 150,000,including more than 32,000 people here in the U.S. While those numbers are frightening, it is apparent that the toll would be far higher without adequate supplies of reliable electricity. Modern healthcare systems depend on electricity. Hospitals are particularly big consumers. Power demand in hospitals is about 36 watts per square meter, which is about six times higher than the electricity load in a typical American home, and utilities are turning to AI to adapt to electricity demands during surges. 

Beating the coronavirus is all about electricity. Indeed, nearly every aspect of coronavirus detection, testing, and treatment requires juice. Second, it appears that the virus is more deadly in places where electricity is scarce or unreliable. Finally, if there are power outages in virus hotspots or hospitals, a real risk in a grid with more blackouts than other developed countries, the damage will be even more severe. 

As my nurse friend in Ventura County made clear, her ability to provide high-quality care for patients is wholly dependent on reliable electricity. The thermometers used to check for fever are powered by electricity. The monitors she uses to keep track of her patients, as well as her Vocera, the walkie-talkie that she uses to communicate with her colleagues, runs on batteries. Testing for the virus requires electricity. One virus-testing machine, Abbott Labs’ m2000, is a 655-pound appliance that, according to its specification sheet, runs on either 120 or 240 volts of electricity. The operating manual for a ventilator made by Hamilton Medical is chock full of instructions relating to electricity, including how to manage the machine’s batteries and alarms. 

While it may be too soon to make a direct connection between lack of electricity and the lethality of the coronavirus, the early signs from the Navajo reservation indicate that energy poverty amplifies the danger. The sprawling reservation has about 175,000 residents, but it has a higher death toll from the virus than 13 states. About 10 percent of Navajos do not have electricity in their homes and more than 30 percent lack indoor plumbing. 

The death rate from the virus on the reservation now stands at 3.4 percent, which is nearly twice the global average. In the middle of last week, the entire population of Native American tribes in the U.S. accounted for about 1,100 confirmed cases of the virus and about 44 deaths. Navajos accounted for the majority of those, with 830 confirmed cases of coronavirus and 28 deaths. 

On Saturday night, the Navajo Times reported a major increase, with 1,197 positive cases of COVID-19 on the reservation and 44 deaths. Other factors may contribute to the high infection and mortality rates on the reservation, including  high rates of diabetes, obesity, and crowded residential living situations. That said, electricity and water are essential to good hygiene and health authorities say that frequent hand washing helps cut the risk of contracting the virus. 

The devastation happening on Navajoland provides a window into what may happen in crowded, electricity-poor countries like India, Pakistan, and Bangladesh. It also shows what could happen if a tornado or hurricane were to wipe out the electric grid in virus hotspots like New Orleans, as extreme weather increasingly afflicts the grid nationwide. Sure, most American hospitals have backup generators to help assure reliable power. But those generators can fail. Further, they usually burn diesel fuel which needs to be replenished every few days. 

The essential point here is that our hospitals and critical health care machines aren’t running on solar panels and batteries. Instead, they are running on grid power that’s being provided by reliable sources — coal, natural gas, hydro, and nuclear power — which together produce about 89 percent of the electricity consumed in this country, even as Russian hacking of utilities highlights cyber risks. The pandemic — which is inflicting trillions of dollars of damage on our economy and tens of thousands of deaths — underscores the criticality of abundant and reliable electricity to our society and the tremendous damage that would occur if our health care infrastructure were to be hit by extended blackouts during the fight to stop COVID-19.

In a follow-up interview on Saturday with my friend, C., she told me that while caring for patients, she and her colleagues “are entirely dependent on electricity. We take it for granted. It’s a hidden assumption in our work,” a reminder echoed by a grid report card that warns of dangerous vulnerabilities. She quickly added she and her fellow nurses “aren’t trained or equipped to deal with circumstances that would come with shoddy power. If we lost power completely, people will die.”

Biden Imposes Higher Tariffs on Chinese Electric Cars and Solar Cells

U.S. Tariffs on Chinese EVs and Solar Cells target trade imbalances, subsidies, and intellectual property risks, bolstering domestic manufacturing, supply chains, and national security across clean energy, automotive technology, and renewable markets.

 

Key Points

Policy measures raising duties on Chinese EVs and solar cells to protect U.S. industry, IP, and national security.

✅ Raises duties to counter subsidies and IP risks

✅ Supports domestic EV and solar manufacturing jobs

✅ May reshape supply chains, prices, and trade flows

 

In a significant move aimed at bolstering domestic industries and addressing trade imbalances, the Biden administration has announced higher tariffs on Chinese-made electric cars and solar cells. This decision marks a strategic shift in U.S. trade policy, with market observers noting EV tariffs alongside industrial and financial implications across sectors today.

Tariffs on Electric Cars

The imposition of tariffs on Chinese electric cars comes amidst growing competition in the global electric vehicle (EV) market. U.S. automakers and policymakers have raised concerns about unfair trade practices, subsidies, and market access barriers faced by American EV manufacturers in China amid escalating trade tensions with key partners. The tariffs aim to level the playing field and protect U.S. interests in the burgeoning electric vehicle sector.

Impact on Solar Cells

Similarly, higher tariffs on Chinese solar cells address concerns regarding intellectual property theft, subsidies, and market distortions in the solar energy industry, where tariff threats have influenced investment signals across North American markets.

The U.S. solar sector, a key player in renewable energy development, has called for measures to safeguard fair competition and promote domestic manufacturing of solar technologies.

Economic and Political Implications

The tariff hikes underscore broader economic tensions between the United States and China, spanning trade, technology, and geopolitical issues. While aimed at protecting American industries, these tariffs could lead to retaliatory measures from China and impact global supply chains, particularly in renewable energy and automotive sectors, as North American electricity exports at risk add to uncertainty across markets.

Industry and Market Responses

Industry stakeholders have responded with mixed reactions to the tariff announcements. U.S. automakers and solar manufacturers supportive of the tariffs argue they will help level the playing field and encourage domestic production. However, critics warn of potential energy price spikes for consumers, supply chain disruptions, and unintended consequences for global clean energy goals.

Strategic Considerations

The Biden administration's tariff policy reflects a broader strategy to promote economic resilience, innovation, and national security in critical industries, even as cross-border electricity exports become flashpoints in trade policy debates today.

Efforts to strengthen domestic supply chains, invest in renewable energy infrastructure, and foster international partnerships remain central to U.S. economic competitiveness and climate objectives.

Future Outlook

Looking ahead, navigating U.S.-China trade relations will continue to be a complex challenge for policymakers. Balancing economic interests, diplomatic engagements, and environmental priorities, alongside regional public support for tariffs, will shape future trade policy decisions affecting electric vehicles, renewable energy, and technology sectors globally.

Conclusion

The Biden administration's decision to impose higher tariffs on Chinese electric cars and solar cells represents a strategic response to economic and geopolitical dynamics reshaping global markets. While aimed at protecting American industries and promoting fair trade practices, the tariffs signal a commitment to fostering competitiveness, innovation, and sustainability in critical sectors of the economy. As these measures unfold, stakeholders will monitor their impact on industry dynamics, supply chain resilience, and international trade relations in the evolving landscape of global commerce.

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!”

Solar power is the red-hot growth area in oil-rich Alberta

Alberta Solar Power is accelerating as renewable energy investment, PPAs, and utility-scale projects expand the grid, with independent power producers and foreign capital outperforming AESO forecasts in oil-and-gas-rich markets across Alberta and Calgary.

 

Key Points

Alberta Solar Power is a fast-growing provincial market, driven by PPAs and private investment, outpacing AESO forecasts.

✅ Utility-scale projects and PPAs expand capacity beyond AESO outlooks

✅ Private and foreign capital drive independent power producers

✅ Costs near $70/MWh challenge >$100/MWh assumptions

 

Solar power is beating expectations in oil and gas rich Alberta, where the renewable energy source is poised to expand dramatically amid a renewable energy surge in the coming years as international power companies invest in the province.

Fresh capital is being deployed in the Alberta’s electricity generation sector for both renewable and natural gas-fired power projects after years of uncertainty caused by changes and reversals in the province’s power market, said Duane Reid-Carlson, president of power consulting firm EDC Associates, who advises renewable power developers on electric projects in the province.

“From the mix of projects that we see in the queue at the (Alberta Electric System Operator) and the projects that have been announced, Alberta, a powerhouse for both green energy and fossil fuels, has no shortage of thermal and renewable projects,” Reid-Carlson said, adding that he sees “a great mix” of independent power companies and foreign firms looking to build renewable projects in Alberta.

Alberta is a unique power market in Canada because its electricity supply is not dominated by a Crown corporation such as BC Hydro, Hydro One or Hydro Quebec. Instead, a mix of private-sector companies and a few municipally owned utilities generate electricity, transmit and distribute that power to households and industries under long-term contracts.

Last week, Perimeter Solar Inc., backed by Danish solar power investor Obton AS, announced Sept. 30 that it had struck a deal to sell renewable energy to Calgary-based pipeline giant TC Energy Corp. with 74.25 megawatts of electricity from a new 130-MW solar power project immediately south of Calgary. Neither company disclosed the costs of the transaction or the project.

“We are very pleased that of all the potential off-takers in the market for energy, we have signed with a company as reputable as TC Energy,” Obton CEO Anders Marcus said in a release announcing the deal, which it called “the largest negotiated energy supply agreement with a North American energy company.”

Perimeter expects to break ground on the project, which will more than double the amount of solar power being produced in the province, by the end of this year.

A report published Monday by the Energy Information Administration, a unit of the U.S. Department of Energy, estimated that renewable energy powered 3 per cent of Canada’s energy consumption in 2018.

Between the Claresholm project and other planned solar installations, utility companies are poised to install far more solar power than the province is currently planning for, even as Alberta faces challenges with solar expansion today.

University of Calgary adjunct professor Blake Shaffer said it was “ironic” that the Claresholm Solar project was announced the exact same day as the Alberta Electric System Operator released a forecast that under-projected the amount of solar in the province’s electric grid.

The power grid operator (AESO) released its forecast on Sept. 30, which predicted that solar power projects would provide just 1 per cent of Alberta’s electricity supply by 2030 at 231 megawatts.

Shaffer said the AESO, which manages and operates the province’s electricity grid, is assuming that on a levelized basis solar power will need a price over $100 per megawatt hour for new investment. However, he said, based on recent solar contracts for government infrastructure projects, the cost is closer to $70 MW/h.
