Fayette County Community Action Agency has opened the first green building in Uniontown.

"People have been asking me, 'What the heck is a green building?'," said James Stark, the CEO of Fayette County Community Action Agency. It's another name for an environmentally friendly building designed to cut operation costs and reduce carbon emissions and other waste that could be hazardous to the environment.

The 18,000-square-foot facility at 108 N. Beeson Ave. is fitted with bicycle storage, changing room, alternative fuel vehicle parking with charging station, special parking for car pooling, reduced heat island roof (painted white to reflect heat), water efficient landscaping, two flush toilets, waterless urinals, sensor-controlled faucets, optimized energy use, use of solar panels for power and hot water, a geothermal heat pump, sensor-controlled lighting and more.

"And it's powered by wind power, too," said Gregory R. Asbee, a graduate architect for Altman and Altman, the architectural firm that designed the building. Asbee said all the products used in the building were purchased locally to cut down on vehicle waste.

An estimated 95 percent of the materials from the demolition of the previous structure was recycled in some way. Along with the environmental benefits of the building, the heat sources and water usage will save on monthly utility bills and the building is healthier for employees and those who visit the site.

The indoor qualities include no tobacco smoking, carbon dioxide monitoring, continuous fresh air, indoor air quality measures, low VOC emitting materials with the use of specialized adhesives and sealants and paints, indoor chemical and pollutant source control and thermal comfort controls every 1,000 square feet.

"I went on a tour of this building, and I'm very impressed," said state Rep. Tim Mahoney, who added that the features of the new building go hand in hand with the services that the FCCAA provides the poor and elderly in the area. State Rep. Ted Harhai is familiar with green buildings. One was recently dedication in Monessen. "This is a growing movement, not a passing fad," Harhai said.

"These projects are valuable, and they benefit the community." Fayette County Commissioner Vincent Vicites said it was great to see more development happening in Fayette County, and lauded FCCAA. "They have a tremendous vision, and they're always looking to build," Vicites said.

"And now they have five buildings and one of them is a green building."

Uniontown Mayor James Sileo said the FCCAA has been instrumental in the process of the renovation of the Uniontown area and the resurgence of the local economy. "Uniontown has a bright, bright future," Sileo said.

Europe Is Losing Nuclear Power Just When It Really Needs Energy

Europe's Nuclear Energy Policy shapes responses to the energy crisis, soaring gas prices, EU taxonomy rules, net-zero goals, renewables integration, baseload security, SMRs, and Russia-Ukraine geopolitics, exposing cultural, financial, and environmental divides.

 

Key Points

A policy guiding nuclear exits or expansion to balance energy security, net-zero goals, costs, and EU taxonomy.

✅ Divergent national stances: phase-outs vs. new builds

✅ Costs, delays, and waste challenge large reactors

✅ SMRs, renewables, and gas shape net-zero pathways

 

As the Fukushima disaster unfolded in Japan in 2011, then-German Chancellor Angela Merkel made a dramatic decision that delighted her country’s anti-nuclear movement: all reactors would be ditched.

What couldn’t have been predicted was that Europe would find itself mired in one of the worst energy crises in its history. A decade later, the continent’s biggest economy has shut down almost all its capacity already. The rest will be switched off at the end of 2022 — at the worst possible time.

Wholesale power prices are more than four times what they were at the start of the coronavirus pandemic. Governments are having to take emergency action to support domestic and industrial consumers faced with crippling bills, which could rise higher if the tension over Ukraine escalates. The crunch has not only exposed Europe’s supply vulnerabilities, but also the entrenched cultural and political divisions over the nuclear industry and a failure to forge a collective vision. 

Other regions meanwhile are cracking on, challenging the idea that nuclear power is in decline worldwide. China is moving fast on nuclear to try to clean up its air quality. Its suite of reactors is on track to surpass that of the U.S., the world’s largest, by as soon as the middle of this decade. Russia is moving forward with new stations at home and has more than 20 reactors confirmed or planned for export construction, according to the World Nuclear Association.

“I don’t think we’re ever going to see consensus across Europe with regards to the continued running of existing assets, let alone the construction of new ones,” said Peter Osbaldstone, research director for power and renewables at Wood Mackenzie Group Ltd. in the U.K. “It’s such a massive polarizer of opinions that national energy policy is required in strength over a sustained period to support new nuclear investment.” 

France, Europe’s most prolific nuclear energy producer, is promising an atomic renaissance as its output becomes less reliable. Britain plans to replace aging plants in the quest for cleaner, more reliable energy sources. The Netherlands wants to add more capacity, Poland also is seeking to join the nuclear club, and Finland is starting to produce electricity later this month from its first new plant in four decades. 

Belgium and Spain, meanwhile, are following Germany’s lead in abandoning nuclear, albeit on different timeframes. Austria rejected it in a referendum in 1978.

Nuclear power is seen by its proponents as vital to reaching net-zero targets worldwide. Once built, reactors supply low-carbon electricity all the time, unlike intermittent wind or solar.

Plants, though, take a decade or more to construct at best and the risk is high of running over time and over budget. Finland’s new Olkiluoto-3 unit is coming on line after a 12-year delay and billions of euros in financial overruns. 

Then there’s the waste, which stays hazardous for 100,000 years. For those reasons European Union members are still quarreling over whether nuclear even counts as sustainable.

Electorates are also split. Polling by YouGov Plc published in December found that Danes, Germans and Italians were far more nuclear-skeptic than the French, British or Spanish. 

“It comes down to politics,” said Vince Zabielski, partner at New York-based law firm Pillsbury Winthrop Shaw Pittman LLP, who was a nuclear engineer for 15 years. “Everything political ebbs and flows, but when the lights start going off people have a completely different perspective.”

 

What’s Behind Europe’s Skyrocketing Energy Prices

Indeed, there’s a risk of rolling blackouts this winter. Supply concerns plaguing Europe have sent gas and electricity prices to record levels and inflation has ballooned. There’s also mounting tension with Russia over a possible invasion of Ukraine, which could lead to disrupted supplies of gas. All this is strengthening the argument that Europe needs to reduce its dependence on international sources of gas.

Europe will need to invest 500 billion euros ($568 billion) in nuclear over the next 30 years to meet growing demand for electricity and achieve its carbon reduction targets, according to Thierry Breton, the EU’s internal market commissioner. His comments come after the bloc unveiled plans last month to allow certain natural gas and nuclear energy projects to be classified as sustainable investments. 

“Nuclear power is a very long-term investment and investors need some kind of guarantee that it will generate a payoff,” said Elina Brutschin at the International Institute for Applied Systems Analysis. In order to survive in liberalized economies like the EU, the technology needs policy support to help protect investors, she said.

That already looks like a tall order. The European Commission has been told by a key expert group that the labeling risks raising greenhouse gas emissions and undermining the bloc’s reputation as a bastion for environmentally friendly finance.

Austria has threatened to sue the European Commission over attempts to label atomic energy as green. The nation previously attempted a legal challenge, when the U.K. was still an EU member, to stop the construction of Electricite de France SA’s Hinkley Point C plant, in the west of England. It has also commenced litigation against new Russia-backed projects in neighboring Hungary.

Germany, which has missed its carbon emissions targets for the past two years, has been criticized by some environmentalists and climate scientists for shutting down a supply of clean power at the worst time, despite arguments for a nuclear option for climate policy. Its final three reactors will be halted this year. Yet that was never going to be reversed with the Greens part of the new coalition government. 

The contribution of renewables in Germany has almost tripled since the year before Fukushima, and was 42% of supply last year. That’s a drop from 46% from the year before and means the country’s new government will have to install some 3 gigawatts of renewables — equivalent to the generating capacity of three nuclear reactors — every year this decade to hit the country's 80% goal.

“Other countries don’t have this strong political background that goes back to three decades of anti-nuclear protests,” said Manuel Koehler, managing director of Aurora Energy Research Ltd., a company analyzing power markets and founded by Oxford University academics. 

At the heart of the issue is that countries with a history of nuclear weapons will be more likely to use the fuel for power generation. They will also have built an industry and jobs in civil engineering around that.

Germany’s Greens grew out of anti-nuclear protest movements against the stationing of U.S. nuclear missiles in West Germany. The 1986 Chernobyl meltdown, which sent plumes of radioactive fallout wafting over parts of western Europe, helped galvanize the broader population. Nuclear phase-out plans were originally laid out in 2002, but were put on hold by the country's conservative governments. The 2011 Fukushima meltdowns reinvigorated public debate, ultimately prompting Merkel to implement them.

It’s not easy to undo that commitment, said Mark Hibbs, a Bonn, Germany-based nuclear analyst at Carnegie Endowment for International Peace, or to envision any resurgence of nuclear in Germany soon: “These are strategic decisions, that have been taken long in advance.”

In France, President Emmanuel Macron is about to embark on a renewed embrace of nuclear power, even as a Franco-German nuclear dispute complicates the debate. The nation produces about two-thirds of its power from reactors and is the biggest exporter of electricity in Europe. Notably, that includes anti-nuclear Germany and Austria.

EDF, the world’s biggest nuclear plant operator, is urging the French government to support construction of six new large-scale reactors at an estimated cost of about 50 billion euros. The first of them would start generating in 2035.

But even France has faced setbacks. Development of new projects has been put on hold after years of technical issues at the Flamanville-3 project in Normandy. The plant is now scheduled to be completed next year. 

In the U.K., Business Secretary Kwasi Kwarteng said that the global gas price crisis underscores the need for more home-generated clean power. By 2024, five of Britain’s eight plants will be shuttered because they are too old. Hinkley Point C is due to be finished in 2026 and the government will make a final decision on another station before an election due in 2024. 

One solution is to build small modular reactors, or SMRs, which are quicker to construct and cheaper. The U.S. is at the forefront of efforts to design smaller nuclear systems with plans also underway in the U.K. and France. Yet they too have faced delays. SMR designs have existed for decades though face the same challenging economic metrics and safety and security regulations of big plants.

The trouble, as ever, is time. “Any investment decisions you make now aren’t going to come to fruition until the 2030s,” said Osbaldstone, the research director at Wood Mackenzie. “Nuclear isn’t an answer to the current energy crisis.”

Trump's Proposal to Control Ukraine's Nuclear Plants Sparks Controversy

US Control of Ukraine Nuclear Plants sparks debate over ZNPP, Zaporizhzhia, sovereignty, safety, ownership, and international cooperation, as Washington touts utility expertise, investment, and modernization to protect critical energy infrastructure amid conflict.

 

Key Points

US management proposal for Ukraine's nuclear assets, notably ZNPP, balancing sovereignty, safety, and investment.

✅ Ukraine retains ownership; any transfer requires parliament approval.

✅ ZNPP safety risks persist amid occupation near active conflict.

✅ International reactions split: sovereignty vs. cooperation and investment.

 

In a recent phone call with Ukrainian President Volodymyr Zelenskyy, U.S. President Donald Trump proposed that the United States take control of Ukraine's nuclear power plants, including the Zaporizhzhia Nuclear Power Plant (ZNPP), which has been under Russian occupation since early in the war and where Russia is reportedly building power lines to reactivate the plant amid ongoing tensions. Trump suggested that American ownership of these plants could be the best protection for their infrastructure, a proposal that has sparked controversy in policy circles, and that the U.S. could assist in running them with its electricity and utility expertise.

Ukrainian Response

President Zelenskyy promptly addressed Trump's proposal, stating that while the conversation focused on the ZNPP, the issue of ownership was not discussed. He emphasized that all of Ukraine's nuclear power plants belong to the Ukrainian people and that any transfer of ownership would require parliamentary approval . Zelenskyy clarified that while the U.S. could invest in and help modernize the ZNPP, ownership would remain with Ukraine.

Security Concerns

The ZNPP, Europe's largest nuclear facility, has been non-operational since its occupation by Russian forces in 2022. The plant's location near active conflict zones raises significant safety risks that the IAEA has warned of in connection with attacks on Ukraine's power grids, and its future remains uncertain. Ukrainian officials have expressed concerns about potential Russian provocations, such as explosions, especially after UN inspectors reported mines at the Zaporizhzhia plant near key facilities, if and when Ukraine attempts to regain control of the plant.

International Reactions

The proposal has elicited mixed reactions both within Ukraine and internationally. Some Ukrainian officials view it as an opportunistic move by the U.S. to gain control over critical infrastructure, while others see it as a potential avenue for modernization and investment, alongside expanding wind power that is harder to destroy in wartime. The international community remains divided on the issue, with some supporting Ukraine's sovereignty over its nuclear assets and others advocating for a possible agreement on power plant attacks to ensure the plant's safety and future operation.

President Trump's proposal to have the U.S. take control of Ukraine's nuclear power plants has sparked significant controversy. While the U.S. offers expertise and investment, Ukraine maintains that ownership of its nuclear assets is a matter of national sovereignty, even as it has resumed electricity exports to bolster its economy. The situation underscores the complex interplay between security, sovereignty, and international cooperation in conflict zones.

GM president: Electric cars won't go mainstream until we fix these problems

Electric Vehicle Adoption Barriers include range anxiety, charging infrastructure, and cost parity; consumer demand, tax credits, lithium-ion batteries, and performance benefits are accelerating EV uptake, pushing SUVs and self-driving tech toward mainstream mobility.

 

Key Points

They are the key hurdles to mainstream EV uptake: range anxiety, sparse charging networks, and high upfront costs.

✅ Range targets of 300+ miles reduce anxiety and match ICE convenience

✅ Expanded home, work, and public charging speeds adoption

✅ Falling battery costs and incentives drive price parity

 

The automotive industry is hurtling toward a future that will change transportation the same way electricity changed how we light the world. Electric and self-driving vehicles will alter the automotive landscape forever — it's only a question of how soon, and whether the age of electric cars arrives ahead of schedule.

Like any revolution, this one will be created by market demand.
Beyond the environmental benefit, electric vehicle owners enjoy the performance, quiet operation, robust acceleration, style and interior space. And EV owners like not having to buy gasoline. We believe the majority of these customers will stay loyal to electric cars, and U.S. EV sales are soaring into 2024 as this loyalty grows.

But what about non-EV owners? Will they want to buy electric, and is it time to buy an electric car for them yet? About 25 years ago, when we first considered getting into the electric vehicle business with a small car that had about 70 miles of range, the answer was no. But today, the results are far more encouraging.

We recently held consumer clinics in Los Angeles and Chicago and presented people with six SUV choices: three gasoline and three electric. When we asked for their first choice to purchase, 40% of the Chicago respondents chose an electric SUV, and 45% in LA did the same. This is despite a several thousand-dollar premium on the price of the electric models, and despite that EV sales still lag gas cars nationally today, consumer interest was strong (but also before crucial government tax credits that we believe will continue to drive people toward electric vehicles and help fuel market demand).

They had concerns, to be sure. Most people said they want vehicles that can match gasoline-powered vehicles in range, ease of ownership and cost. The sooner we can break down these three critical barriers, the sooner electric cars will become mainstream.

Range
Range is the single biggest barrier to EV acceptance. Just as demand for gas mileage doesn't go down when there are more gas stations, demand for better range won't ease even as charging infrastructure improves. People will still want to drive as long as possible between charges.

Most consumers surveyed during our clinics said they want at least 300 miles of range. And if you look at the market today, which is driven by early adapters, electric cars have hit an inflection point in demand, and the numbers bear that out. The vast majority of electric vehicles sold — almost 90% — are six models with the highest range of 238 miles or more — three Tesla models, the Chevrolet Bolt EV, the Hyundai Kona and the Kia Niro, according to IHS Markit data.

Lithium-ion batteries, which power virtually all electric cars on the road today, are rapidly improving, increasing range with each generation. At GM, we recently announced that our 2020 Chevrolet Bolt EV will have a range of 259 miles, a 21-mile improvement over the previous model. Range will continue to improve across the industry, and range anxiety will dissipate.

Charging infrastructure
Our research also shows that, among those who have considered buying an electric vehicle, but haven't, the lack of charging stations is the number one reason why.

For EVs to gain widespread acceptance, manufacturers, charging companies, industry groups and governments at all levels must work together to make public charging available in as many locations as possible. For example, we are seeing increased partnership activity between manufacturers and charging station companies, as well as construction companies that build large infrastructure projects, as the American EV boom approaches, with the goal of adding thousands of additional public charging stations in the United States.

Private charging stations are just as important. Nearly 80% of electric vehicle owners charge their vehicles at home, and almost 15% at work, with the rest at public stations, our research shows. Therefore, continuing to make charging easy and seamless is vital. To that end, more partnerships with companies that will install the chargers in consumers' homes conveniently and affordably will be a boon for both buyers and sellers.

Cost
Another benefit to EV ownership is a lower cost of operation. Most EV owners report that their average cost of operation is about one-third of what a gasoline-powered car owner pays. But the purchase price is typically significantly higher, and that's where we should see change as each generation of battery technology improves efficiency and reduces cost.

Looking forward, we think electric vehicle propulsion systems will achieve cost parity with internal combustion engines within a decade or sooner, and will only get better after that, driving sticker prices down and widening the appeal to the average consumer. That will be driven by a number of factors, including improvements with each generation of batteries and vehicles, as well as expected increased regulatory costs on gasoline and diesel engines.

Removing these barriers will lead to what I consider the ultimate key to widespread EV adoption — the emergence of the EV as a consumer's primary vehicle — not a single-purpose or secondary vehicle. That will happen when we as an industry are able to offer the utility, cost parity and convenience of today's internal combustion-based cars and trucks.

To get the electric vehicle to first-string status, manufacturers simply must make it as good or better than the cars, trucks and crossovers most people are used to driving today. And we must deliver on our promise of making affordable, appealing EVs in the widest range of sizes and body styles possible. When we do that, electric vehicle adoption and acceptance will be widespread, and it can happen sooner than most people think.

Mark Reuss is president of GM. The opinions expressed in this commentary are his own.

Philippines Ranks Highest in Coal-Generated Power Dependency

Philippines coal dependency underscores energy transition challenges, climate change risks, and air pollution, as rising electricity demand, fossil fuels, and emissions shape policy shifts toward renewable energy, grid reliability, and sustainable development.

 

Key Points

It is rising reliance on coal for power, driven by demand and cost, with climate, air pollution, and policy risks.

✅ Driven by rising demand, affordability, and grid reliability.

✅ Worsens emissions, air pollution, and public health burdens.

✅ Policy shifts aim at renewable energy, efficiency, and standards.

 

In a striking development, the Philippines has surpassed China and Indonesia to become the nation most dependent on coal-generated power in recent years. This shift highlights significant implications for the country's energy strategy, environmental policies, and its commitment to sustainable development, and comes as global power demand continues to surge worldwide.

Rising Dependency on Coal

The Philippines' increasing reliance on coal-generated power is driven by several factors, including rapid economic growth, rising electricity demand, and regional uncertainties in China's electricity sector that influence fuel markets, and the perceived affordability and reliability of coal as an energy source. Coal has historically been a key component of the Philippines' energy mix, providing a stable supply of electricity to support industrialization and urbanization efforts.

Environmental and Health Impacts

Despite its economic benefits, coal-generated power comes with significant environmental and health costs, especially as soaring electricity and coal use amplifies exposure to pollution. Coal combustion releases greenhouse gases such as carbon dioxide, contributing to global warming and climate change. Additionally, coal-fired power plants emit pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which pose health risks to nearby communities and degrade air quality.

Policy and Regulatory Landscape

The Philippines' energy policies have evolved to address the challenges posed by coal dependency while promoting sustainable alternatives. The government has introduced initiatives to encourage renewable energy development, improve energy efficiency, and, alongside stricter emissions standards on coal-fired power plants, is evaluating nuclear power for inclusion in the energy mix to meet future demand. However, balancing economic growth with environmental protection remains a complex and ongoing challenge.

International and Domestic Pressures

Internationally, there is growing pressure on countries to reduce reliance on fossil fuels and transition towards cleaner energy sources as part of global climate commitments under the Paris Agreement, illustrated by the United Kingdom's plan to end coal power within its grid. The Philippines' status as the most coal-dependent nation underscores the urgency for policymakers to accelerate the shift towards renewable energy and reduce carbon emissions to mitigate climate impacts.

Challenges and Opportunities

Transitioning away from coal-generated power presents both challenges and opportunities for the Philippines. Challenges include overcoming entrenched interests in the coal industry, addressing energy security concerns, and navigating the economic implications of energy transition, particularly as clean energy investment in developing nations has recently declined, adding financial headwinds. However, embracing renewable energy offers opportunities to diversify the energy mix, reduce dependence on imported fuels, create green jobs, and improve energy access in remote areas.

Community and Stakeholder Engagement

Engaging communities and stakeholders is crucial in shaping the Philippines' energy transition strategy. Local residents, environmental advocates, industry leaders, and policymakers play essential roles in fostering dialogue, raising awareness about the benefits of renewable energy, and advocating for policies that promote sustainable development and protect public health.

Future Outlook

The Philippines' path towards reducing coal dependency and advancing renewable energy is critical to achieving long-term sustainability and resilience against climate change impacts. By investing in renewable energy infrastructure, enhancing energy efficiency measures, and fostering innovation in clean technologies, as renewables poised to eclipse coal indicate broader momentum, the country can mitigate environmental risks, improve energy security, and contribute to global efforts to combat climate change.

Conclusion

As the Philippines surpasses China and Indonesia in coal-generated power dependency, the nation faces pivotal decisions regarding its energy future. Balancing economic growth with environmental stewardship requires strategic investments in renewable energy, robust policy frameworks, and proactive engagement with stakeholders to achieve a sustainable and resilient energy system. By prioritizing clean energy solutions, the Philippines can pave the way towards a greener and more sustainable future for generations to come.

Australia to head huge electricity and internet project in PNG

Australia-PNG Infrastructure Rollout delivers electricity and broadband expansion across PNG, backed by New Zealand, the US, Japan, and South Korea, enhancing telecom capacity, digital connectivity, and regional development ahead of the APEC summit.

 

Key Points

A multi-billion-dollar plan to expand power and broadband in PNG, covering 70% of users with allied support.

✅ Delivers internet to 70% of PNG households and communities

✅ Expands electricity grid, boosting reliability and access

✅ Backed by NZ, US, Japan, and S. Korea; complements APEC investments

 

Australia will lead a new multi-billion-dollar electricity and internet rollout in Papua New Guinea, with the PM rules out taxpayer-funded power plants stance underscoring its approach to energy policy.

The Australian newspaper reported New Zealand, the US, Japan, whose utilities' offshore wind deal in the UK signaled expanding energy interests, and South Korea are supporting the project, which will be PNG's largest ever development investment.

The project will deliver internet to 70 percent of PNG and improve access to power, even as clean energy investment in developing nations has slipped sharply, according to a recent report.

Both China and the US are also expected to announce new investments in the region at the APEC summit this week, and recent China-Cambodia nuclear energy cooperation underscores those energy ties.

Beijing will announce new mining and energy investments in PNG, echoing projects such as the Chinese-built electricity poles plant in South Sudan, and two Confucius Insitutes to be housed at PNG universities.

Some old dams are being given a new power: generating clean electricity

Hydroelectric retrofits for unpowered dams leverage turbines to add renewable capacity, bolster grid reliability, and enable low-impact energy storage, supporting U.S. and Canada decarbonization goals with lower costs, minimal habitat disruption, and climate resilience.

 

Key Points

They add turbines to existing dams to make clean power, stabilize the grid, and offer low-impact storage at lower cost.

✅ Lower capex than new dams; minimal habitat disruption

✅ Adds firming and storage to support wind and solar

✅ New low-head turbines unlock more retrofit sites

 

As countries race to get their power grids off fossil fuels to fight climate change, there's a big push in the U.S. to upgrade dams built for purposes such as water management or navigation with a feature they never had before — hydroelectric turbines. 

And the strategy is being used in parts of Canada, too, with growing interest in hydropower from Canada supplying New York and New England.

The U.S. Energy Information Administration says only three per cent of 90,000 U.S. dams currently generate electricity. A 2012 report from the U.S. Department of Energy found that those dams have 12,000 megawatts (MW) of potential hydroelectric generation capacity. (According to the National Hydropower Association, 1 MW can power 750 to 1,000 homes. That means 12,000 MW should be able to power more than nine million homes.)

As of May 2019, there were projects planned to convert 32 unpowered dams to add 330 MW to the grid over the next several years.

One that was recently completed was the Red Rock Hydroelectric Project, a 60-year-old flood control dam on the Des Moines River in Iowa that was retrofitted in 2014 to generate 36.4 MW at normal reservoir levels, and up to 55 MW at high reservoir levels and flows. It started feeding power to the grid this spring, and is expected to generate enough annually to supply power to 18,000 homes.

It's an approach that advocates say can convert more of the grid from fossil fuels to clean energy, often with a lower cost and environmental impact than building new dams.

Hydroelectric facilities can also be used for energy storage, complementing intermittent clean energy sources such as wind and solar with pumped storage to help maintain a more reliable, resilient grid.

The Nature Conservancy and the World Wildlife Fund are two environmental groups that oppose new hydro dams because they can block fish migration, harm water quality, damage surrounding ecosystems and release methane and CO2, and in some regions, Western Canada drought has reduced hydropower output as reservoirs run low. But they say adding turbines to non-powered dams can be part of a shift toward low-impact hydro projects that can support expansion of solar and wind power.

Paul Norris, president of the Ontario Waterpower Association, said there's typically widespread community support for such projects in his province amid ongoing debate over whether Ontario is embracing clean power in its future plans. "Any time that you can better use existing assets, I think that's a good thing."

New turbine technology means water doesn't need to fall from as great a height to generate power, providing opportunities at sites that weren't commercially viable in the past, Norris said, with recent investments such as new turbines in Manitoba showing what is possible.

In Ontario, about 1,000 unpowered dams are owned by various levels of government. "With the appropriate policy framework, many of these assets have the potential to be retrofitted for small hydro," Norris wrote in a letter to Ontario's Independent Electricity System Operator this year as part of a discussion on small-scale local energy generation resources.

He told CBC that several such projects are already in operation, such as a 950 kW retrofit of the McLeod Dam at the Moira River in Belleville, Ont., in 2008. 

Four hydro stations were going to be added during dam refurbishment on the Trent-Severn Waterway, but they were among 758 renewable energy projects cancelled by Premier Doug Ford's government after his election in 2018, a move examined in an analysis of Ontario's dirtier electricity outlook and its implications.

Patrick Bateman, senior vice-president of Waterpower Canada, said such dam retrofit projects are uncommon in most provinces. "I don't see it being a large part of the future electricity generation capacity."

He said there has been less movement on retrofitting unpowered dams in Canada compared to the U.S., because:

There are a lot more opportunities in Canada to refurbish large, existing hydro-generating stations to boost capacity on a bigger scale.

There's less growth in demand for clean energy, because more of Canada's grid is already non-carbon-emitting (80 per cent) compared to the U.S. (40 per cent).

Even so, Norris thinks Canadians should be looking at all opportunities and options when it comes to transitioning the grid away from fossil fuels, including retrofitting non-powered dams, especially as a recent report highlights Canada's looming power problem over the coming decades.

"If we're going to be serious about addressing the inevitable challenges associated with climate change targets and net zero, it really is an all-of-the-above approach."
