Within 20 years, all new homes will be enviro-misers, producing as much energy as they consume.

By the time teenagers are hitting their mid-life-crisis years, roughly 2030, all new homes built should be net zero energy - they produce as much energy as they consume in a year.

That's a goal the Net-Zero Energy Home Coalition is working toward. And it's a vision shared by federal government housing policy people.

"This is not something that's rocket science," coalition chairman Gordon Shields told a recent gathering of building industry people interested in net-zero principles.

"We can do it and with today's technology."

Over at the CANMET Energy Technology Centre, director general John Marrone agrees. "Net-zero energy is the proverbial holy grail. By 2025 to 2030, this could be a reality, a standard home."

Houses produce 33 per cent of all greenhouse gases and every year we waste as much energy as 10 Pickering, Ont., nuclear power plants produce. Marrone says if you put today's electricity-generating solar photovoltaic panels on all Toronto homes, you could provide enough electricity for the province.

Woyteck Kujawski, a senior housing researcher at Canada Mortgage and Housing Corp., says CMHC would like new homes at net-zero standards by 2030.

Meanwhile, it will continue its EQuilibrium program to help 12 builders across Canada construct net-zero demonstration homes this year. And in the next five years, he wants 1,500 demonstration homes built.

The National Round Table on the Environment and the Economy, set up by the federal government to give advice on such issues, has a housing vision that extends to 2050.

By the time my teenagers are senior citizens, 70 per cent of Canadians will live in multiple dwellings, the round table says. Fully 33 per cent of single-family homes will have solar water heating and 10 per cent will make their own electricity with photovoltaic panels.

And here's an interesting prediction: 66 per cent of the buildings standing in the year 2050 have been built already. That means there will be a huge market for energy-efficient renovations. The remaining 34 per cent must be built to the highest standards or they'll join the list of buildings needing renovations.

Those numbers don't surprise Minto Developments architect Bill Ritcey, who agrees people will be living more densely in multiple dwellings.

Others at the net-zero seminar speculated homes may become their own little power generators. Who knows? Maybe Hydro Ottawa will pay homeowners to "rent" their roofs for solar panels. Ritcey isn't sure about that, although he envisions more community-based power projects, whether for solar electricity or geo-thermal power.

Indian government takes steps to get nuclear back on track

India Nuclear Generation Shortfall highlights missed five-year plan targets due to uranium fuel scarcity, commissioning delays at Kudankulam, PFBR slippage, and PHWR equipment bottlenecks under IAEA safeguards and domestic supply constraints.

 

Key Points

A gap between planned and actual nuclear output due to fuel shortages, reactor delays, and first-of-a-kind hurdles.

✅ Fuel scarcity pre-2009-10 constrained unsafeguarded reactors.

✅ Kudankulam delays from protests, litigation, and remobilisation.

✅ FOAK PHWR equipment bottlenecks and PFBR slippage.

 

A lack of available domestically produced nuclear fuel and delays in constructing and commissioning nuclear power plants, including first-of-a-kind plants and the Prototype Fast Breeder Reactor (PFBR), meant that India failed to meet its nuclear generation targets under the governmental plans over the decade to 2017, even as global project milestones were being recorded elsewhere.

India's nuclear generation target under its 11th five-year plan, covering the period 2007-2012, was 163,395 million units (MUs) and the 12th five-year Plan (2012-17) was 241,748 MUs, Minister of state for the Department of Atomic Energy and the Prime Minister's Office Jitendra Singh told parliament on 6 February. Actual nuclear generation in those periods was 109,642 MUs and 183,488 MUs respectively, Singh said in a written answer to questions in the Lok Sabah.

Singh attributed the shortfall in generation to a lack of availability of the necessary quantities of domestically produced fuel during the three years before 2009-2010; delays to the commissioning of two 1000 MWe nuclear power plants at Kudankulam due to local protests and legal challenges; and delays in the completion of two indigenously designed pressurised heavy water reactors and the PFBR.

Kudankulam 1 and 2 are VVER-1000 pressurised water reactors (PWRs) supplied by Russia's Atomstroyexport under a Russian-financed contract. The units were built by Nuclear Power Corporation of India Ltd (NPCIL) and were commissioned and are operated by NPCIL under International Atomic Energy Agency (IAEA) safeguards, with supervision from Russian specialists, while China's nuclear program advanced on a steady development track in the same period. Construction of the units - the first PWRs to enter operation in India - began in 2002.

Singh said local protests resulted in the halt of commissioning work at Kudankulam for nine months from September 2011 to March 2012, when he said project commissioning had been at its peak. As a consequence, additional time was needed to remobilise the workforce and contractors, he said. Litigation by anti-nuclear groups, and compliance with supreme court directives, impacted commissioning in 2013, he said. Unit 1 entered commercial operation in December 2014 and unit 2 in April 2017.

Delays in the manufacture and supply by domestic industry of critical equipment for first-of-a-kind 700 MWe pressurised heavy water reactors -  Kakrapar units 3 and 4, and Rajasthan units 7 and 8 - has led to delays in the completion of those units, the minister said, as well as noting the delay in completion of the PFBR, which is being built at Kalpakkam by Bhavini. In answer to a separate question, Singh said the PFBR is in an "advance stage of integrated commissioning" and is "expected to approach first criticality by the year 2020."

Eight of India's operating nuclear power plants are not under IAEA safeguards and can therefore only use indigenously-sourced uranium. The other 14 units operate under IAEA safeguards and can use imported uranium. The Indian government has taken several measures to secure fuel supplies for reactors in operation and under construction, amid coal supply rationing pressures elsewhere in the power sector, concluding fuel supply contracts with several countries for existing and future reactors under IAEA Safeguards and by "augmentation" of fuel supplies from domestic sources, Singh said.

Kakrapar 3 and 4, with Kakrapar 3 criticality already reported, and Rajasthan 7 and 8 are all currently expected to enter service in 2022, according to World Nuclear Association information.

 

Joint venture discussions

In February 2016 the government amended the Atomic Energy Act to allow NPCIL to form joint venture companies with other public sector undertakings (PSUs) for involvement in nuclear power generation and possibly other aspects of the fuel cycle, reflecting green industrial strategies shaping future reactor waves globally. In answer to another question, Singh confirmed that NPCIL has entered into joint ventures with NTPC Limited (National Thermal Power Corporation, India's largest power company) and Indian Oil Corporation Limited. Two joint venture companies - Anushakti Vidhyut Nigam Limited and NPCIL-Indian Oil Nuclear Energy Corporation Limited - have been incorporated, and discussions on possible projects to be set up by the joint venture companies are in progress.

An exploratory discussion had also been held with Oil & Natural Gas Corporation, Singh said. Indian Railways - which has in the past been identified as a potential joint venture partner for NPCIL - had "conveyed that they were not contemplating entering into an MoU for setting up of nuclear power plants," Singh said.

Investor: Hydro One has too many unknowns to be a good investment

Hydro One investment risk reflects Ontario government influence, board shakeup, Avista acquisition uncertainty, regulatory hearings, dividend growth prospects, and utility M&A moves in Peterborough, with stock volatility since the 2015 IPO.

 

Key Points

Hydro One investment risk stems from political control, governance turnover, regulatory outcomes, and uncertain M&A.

✅ Ontario retains near-50% stake, affecting autonomy and policy risk

✅ Board overhaul and CEO exit create governance uncertainty

✅ Avista deal, OEB hearings, local utility M&A drive outcomes

 

Hydro One may be only half-owned by the province on Ontario but that’s enough to cause uncertainty about the company’s future, thus making for an investment risk, says Douglas Kee of Leon Frazer & Associates.

Since its IPO in November of 2015, Hydro One has seen its share of ups and downs, including a Q2 profit decline earlier this year, mostly downs at this point. Currently trading at $19.87, the stock has lost 11 per cent of its value in 2018 and 12 per cent over the last 12 months, despite a one-time gain boosting Q2 profit that followed a court ruling.

This year has been a turbulent one, to say the least, as newly elected Ontario premier Doug Ford made good this summer on his campaign promise re Hydro One by forcing the resignation of the company’s 14-person board of directors along with the retirement of its chief executive, an event that saw Hydro One shares fall amid the turmoil. An interim CEO has been found and a new 10-person board and chairman put in place, but Kee says it’s unclear what impact the shakeup will ultimately have, other than delaying a promising-looking deal to purchase US utility Avista Corp, with the companies moving to ask the U.S. regulator to reconsider the order.

 

Douglas Kee’s take on Hydro One stock

“We looked at Hydro One a couple of times two years ago and just decided that with the Ontario government’s still owning a big chunk of the company … there are other public companies where you get the same kind of yield, the same kind of dividend growth, so we just avoided it,” says Kee, managing director and chief investment officer with Leon Frazer & Associates, to BNN Bloomberg.

“The old board versus the new board, I’m not sure that there’s much of an improvement. It was politics more than anything,” he says. “The unfortunate part is that the acquisition they were making in the United States is kind of on hold for now. The regulatory procedures have gone ahead but they are worried, and I guess the new board has to make a decision whether to go ahead with it or not.”

“Their transmissions side is coming up for regulatory hearings next year, which could be difficult in Ontario,” says Kee. “The offset to that is that there are a lot of municipal distributions systems in Ontario that may be sold — they bought one in Peterborough recently, which was a good deal for them. There may be more of that coming too.”

Last month, Hydro One reached an agreement with the City of Peterborough to buy its Peterborough Distribution utility which serves about 37,000 customers for $105 million. Another deal to purchase Orillia Power Distribution Corp for $41 million has been cancelled after an appeal to the Ontario Energy Board was denied in late August. Hydro One’s sought-after Avista Corp acquisition is reported to be worth $7 billion.

Marine Renewables Canada shifts focus towards offshore wind

Marine Renewables Canada Offshore Wind integrates marine renewables, tidal and wave energy, advancing clean electricity, low-carbon power, supply chain development, and regulatory alignment to scale offshore wind energy projects across Canada's coasts and global markets.

 

Key Points

An initiative to grow offshore wind using Canada's marine strengths, shared supply chains, and regulatory synergies.

✅ Leverages tidal and wave energy expertise for offshore wind

✅ Aligns supply chain, safety, and regulatory frameworks

✅ Supports low-carbon power and clean electricity goals

 

With a growing global effort to develop climate change solutions and increase renewable electricity production, including the UK offshore wind growth in recent years, along with Canada’s strengths in offshore and ocean sectors, Marine Renewables Canada has made a strategic decision to grow its focus by officially including offshore wind energy in its mandate.

Marine Renewables Canada plans to focus on similarities and synergies of the resources in order to advance the sector as a whole and ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

“Many of our members working on tidal energy and wave energy projects also have expertise that can service offshore wind projects both domestically and internationally,” says Tim Brownlow, Chair of Marine Renewables Canada. “For us, offshore wind is a natural fit and our involvement will help ensure that Canadian companies and researchers are gaining knowledge and opportunities in the offshore wind sector as it grows.”

Canada has the longest coastlines in the world, giving it huge potential for offshore wind energy development. In addition to the resource, Canada has significant capabilities from offshore and marine industries that can contribute to offshore wind energy projects. The global offshore wind market is estimated to grow by over 650% by 2030 and presents new opportunities for Canadian business.

“The federal government’s recent inclusion of offshore renewables in legislation, including a plan for regulating offshore wind developed by the government, and support for emerging renewable energy technologies are important steps toward building this industry,” says Elisa Obermann, executive director of Marine Renewables Canada. “There are still challenges to address before we’ll see offshore wind energy development in Canada, but we see a great opportunity to get more involved now, increase our experience, and help inform future development.”

Like wave and tidal energy, offshore wind projects operate in harsh marine environments and development presents many of the same challenges and benefits as it does for other marine renewable energy resources. Marine Renewables Canada has recognized that there is significant overlap between offshore wind and wave and tidal energy when it comes to the supply chain, regulatory issues, and the operating environment. The association plans to focus on similarities and synergies of the resources in order to advance the sector as a whole, leveraging Canada’s opportunity in the global electricity market to ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

Why Nuclear Fusion Is Still The Holy Grail Of Clean Energy

Nuclear fusion breakthrough signals progress toward clean energy as NIF lasers near ignition and net energy gain, while tokamak designs like ITER advance magnetic confinement, plasma stability, and self-sustaining chain reactions for commercial reactors.

 

Key Points

A milestone as lab fusion nears ignition and net gain, indicating clean energy via lasers and tokamak confinement.

✅ NIF laser shot approached ignition and triggered self-heating

✅ Tokamak path advances with ITER and stronger magnetic confinement

✅ Net energy gain remains the critical milestone for power plants

 

Just 100 years ago, when English mathematician and astronomer Arthur Eddington suggested that the stars power themselves through a process of merging atoms to create energy, heat, and light, the idea was an unthinkable novelty. Now, in 2021, we’re getting remarkably close to recreating the process of nuclear fusion here on Earth. Over the last century, scientists have been steadily chasing commercial nuclear fusion, ‘the holy grail of clean energy.’ The first direct demonstration of fusion in a lab took place just 12 years after it was conceptualized, at Cambridge University in 1932, followed by the world’s first attempt to build a fusion reactor in 1938. In 1950, Soviet scientists Andrei Sakharov and Igor Tamm propelled the pursuit forward with their development of the tokamak, a fusion device involving massive magnets which is still at the heart of many major fusion pursuits today, including the world’s biggest nuclear fusion experiment ITER in France.

Since that breakthrough, scientists have been getting closer and closer to achieving nuclear fusion. While fusion has indeed been achieved in labs throughout this timeline, it has always required far more energy than it emits, defeating the purpose of the commercial fusion initiative, and elsewhere in nuclear a new U.S. reactor start-up highlights ongoing progress. If unlocked, commercial nuclear fusion would change life as we know it. It would provide an infinite source of clean energy requiring no fossil fuels and leaving behind no hazardous waste products, and many analysts argue that net-zero emissions may be out of reach without nuclear power, underscoring fusion’s promise.

Nuclear fission, the process which powers all of our nuclear energy production now, including next-gen nuclear designs in development, requires the use of radioactive isotopes to achieve the splitting of atoms, and leaves behind waste products which remain hazardous to human and ecological health for up to tens of thousands of years. Not only does nuclear fusion leave nothing behind, it is many times more powerful. Yet, it has remained elusive despite decades of attempts and considerable investment and collaboration from both public and private entities, such as the Gates-backed mini-reactor concept, around the world.

But just this month there was an incredible breakthrough that may indicate that we are getting close. “For an almost imperceptible fraction of a second on Aug. 8, massive lasers at a government facility in Northern California re-created the power of the sun in a tiny hot spot no wider than a human hair,” CNET reported in August. This breakthrough occurred at the National Ignition Facility, where scientists used lasers to set off a fusion reaction that emitted a stunning 10 quadrillion watts of power. Although the experiment lasted for just 100 trillionths of a second, the amount of energy it produced was equal to about “6% of the total energy of all the sunshine striking Earth’s surface at any given moment.”

“This phenomenal breakthrough brings us tantalizingly close to a demonstration of ‘net energy gain’ from fusion reactions — just when the planet needs it,” said Arthur Turrell, physicist and nuclear fusion expert. What’s more, scientists and experts are hopeful that the rate of fusion breakthroughs will continue to speed up, as interest in atomic energy is heating up again across markets, and commercial nuclear fusion could be achieved sooner than ever seemed possible before. At a time when it has never been more important or more urgent to find a powerful and affordable means of producing clean energy, and as policies like the U.K.’s green industrial revolution guide the next waves of reactors, commercial nuclear fusion can’t come fast enough.

Ontario government wants new gas plants to boost electricity production

Ontario Gas Plant Expansion aims to boost grid reliability as nuclear refurbishments proceed, using natural gas to meet electricity demand, despite critics urging renewables, energy storage, and efficiency to reduce carbon emissions, protecting investment growth.

 

Key Points

Ontario plan to expand gas plants for reliability during nuclear outages, sparking debate on emissions and clean options.

✅ IESO data: gas share rose from 4% (2017) to 10.4% (2022).

✅ Government cites nuclear refurbishments and demand growth.

✅ Critics propose storage, wind, solar, and efficiency.

 

The Ontario government is preparing to expand gas-fired power plants in Ontario; a move critics say will make the province's electricity system dirtier and could eventually leave taxpayers on the hook.

The province is currently soliciting bids for additional gas-fired electricity generation, which means new gas plants get built, or existing gas plants get expanded. 

It's poised to be Ontario's biggest increase in the gas-fired power supply in more than a decade since the previous Liberal government scrapped two gas plants, in Mississauga and Oakville, at a cost the auditor general pegged at around $1 billion. 

Doug Ford's energy minister, Todd Smith, says Ontario needs gas plants now to help meet an expected surge in demand for electricity as the province faces a supply shortfall in the coming years and to provide power while some units of the province's nuclear stations are down for refurbishment. 

"It's really important to have natural gas as an insurance policy to keep the lights on and provide the reliability that we need," Smith said in an interview. 

"We need natural gas for the short term, especially to get us through these refurbishments."

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek clean power that emits as little carbon dioxide as possible. 

The portion of Ontario's electricity supply that comes from natural gas matters for the environment and the province's economy. Manufacturing companies increasingly seek a power supply that emits as little carbon dioxide as possible. 

Increasing the amount of gas-fired generation in the electricity system puts Ontario's ability to attract such investments at risk as it complicates balancing demand and emissions across the grid, says Evan Pivnick, program manager with Clean Energy Canada, a think tank. 

"Building new natural gas (power plants) in Ontario today should be seen as an absolute last resort for meeting our energy needs," said Pivnick in an interview. 

Ontario's electricity system has among the lowest rates of CO2 emissions in North America, with roughly half of the annual supply provided by nuclear power, one-quarter from hydro dams, and one-tenth from wind turbines. 

However, Ontario's gas plants have produced a growing amount of electricity in recent years, despite an early report exploring a gas halt by the minister, and that trend will continue if new gas plants are built. 

In 2017, gas- and oil-fired generation provided just four percent of Ontario's electricity supply, according to figures from the provincial agency that manages the grid, the Independent Electricity System Operator (IESO). 

By 2022, that figure reached 10.4 percent. 

Ontario doesn't need new gas plants to meet the electricity demand, says Bryan Purcell, vice president of policy and programs at The Atmospheric Fund. This agency invests in low-carbon projects in the Greater Toronto and Hamilton Area. 

"We're quite concerned about where Ontario's electric grid is going," said Purcell. "Thankfully, there's still time to adjust course and look at other options." 

According to Purcell and Pivnick, those options to avoid gas could include power storage (in which excess generated energy is stored for later use when electricity demand rises), wind and solar projects, or energy efficiency and conservation programs.

U.S. Electric Vehicle Market Share Dips in Q1 2024

U.S. EV Market Share Dip Q1 2024 reflects slower BEV adoption, rising PHEV demand, affordability concerns, charging infrastructure gaps, tax credit shifts, range anxiety, and automaker strategy adjustments across the electric vehicle market.

 

Key Points

Q1 2024 EV and hybrid share slipped as BEV sales lag, PHEVs rise, and affordability and charging concerns temper demand.

✅ BEV share fell to 7.0% as affordable models remain limited

✅ PHEV sales rose 50% YoY, easing range anxiety concerns

✅ Policy shifts and charging gaps weigh on consumer adoption

 

The U.S. electric vehicle (EV) market, once a beacon of unbridled growth, appears to be experiencing a course correction. Data from the U.S. Energy Information Administration (EIA) reveals that the combined market share of electric vehicles (battery electric vehicles, or BEVs) and hybrids dipped slightly in the first quarter of 2024, marking the first decline since the onset of the COVID-19 pandemic, even as EU EV share rose during lockdowns in 2020.

This news comes as a surprise to many analysts who predicted continued exponential growth for the EV market. While overall sales of electric vehicles surged into 2024 and did increase by 7% compared to Q1 2023, this growth wasn't enough to keep pace with the overall rise in vehicle sales. The result: a decline in market share from 18.8% in Q4 2023 to 18.0% in Q1 2024.

Several factors may be contributing to this shift. One potential culprit is a slowdown in battery electric vehicle sales. BEVs saw their share of the market dip from 8.1% to 7.0% in the same period. This could be attributed to a lack of readily available affordable options, with many popular EV models still commanding premium prices and concerns that EV supply may miss demand in the near term.

Another factor could be the rising interest in plug-in hybrid electric vehicles (PHEVs). PHEV sales witnessed a significant jump of 50% year-over-year, reflecting how gas-electric hybrids are getting a boost from major automakers, potentially indicating a consumer preference for vehicles that offer both electric and gasoline powertrain options, addressing concerns about range anxiety often associated with BEVs.

Industry experts offer mixed interpretations of this data. Some downplay the significance of the dip, attributing it to a temporary blip, even though EVs remain behind gas cars in total sales. They point to the ongoing commitment from major automakers to invest in EV production and the potential for new, more affordable models to hit the market soon.

Others express more concern, citing Europe's recent EV slump and suggesting this might be a sign of maturing consumer preferences. They argue that simply increasing the number of EVs on the market might not be enough. Automakers need to address issues like affordability, charging infrastructure, and range anxiety to maintain momentum.

The role of government incentives also remains a question mark. The federal tax credit for electric vehicles is currently set to phase out gradually, potentially impacting consumer purchasing decisions in the future. Continued government support, through incentives or infrastructure development, could be crucial in maintaining consumer interest.

The coming quarters will be crucial in determining the long-term trajectory of the U.S. EV market, especially after the global electric car market's rapid expansion in recent years. Whether this is a temporary setback or a more lasting trend remains to be seen. Addressing consumer concerns, ensuring a diverse range of affordable EV options, and continued government support will all be essential in ensuring the continued growth of this critical sector.

This development also presents an opportunity for traditional automakers. By capitalizing on the growing PHEV market and addressing consumer concerns about affordability and range anxiety, they can carve out a strong position in the evolving automotive landscape.
