Australia on track to tap geothermal potential

Nuclear Power Revival drives decarbonization, climate change mitigation, and energy security with SMRs, Generation IV designs, baseload reliability, and policy support, complementing renewables to meet net-zero targets and growing global electricity demand.

Key Points

A global shift back to nuclear energy, leveraging SMRs and advanced reactors to cut emissions and enhance energy security.

✅ SMRs offer safer, modular, and cost-effective deployment.

✅ Provides baseload power to complement intermittent renewables.

✅ Policy support and investments accelerate advanced designs.

In recent years, nuclear power has experienced a remarkable revival in public interest, policy discussions, and energy investment. Once overshadowed by controversies surrounding safety, waste management, and high costs, nuclear energy is now being reexamined as a vital component of the global energy transition, despite recurring questions such as whether it is in decline from some commentators. Here's why nuclear power is "so hot" right now:

1. Climate Change Urgency

One of the most compelling reasons for the renewed interest in nuclear energy is the urgent need to address climate change. Unlike fossil fuels, nuclear power generates electricity with zero greenhouse gas emissions during operation. As countries rush to meet net-zero carbon targets, evidence that net-zero may require nuclear is gaining traction, and nuclear offers a reliable, large-scale alternative to complement renewable energy sources like wind and solar.

2. Energy Security and Independence

Geopolitical tensions and supply chain disruptions have exposed vulnerabilities in relying on imported fossil fuels, and Europe's shrinking nuclear capacity has sharpened concerns over resilience. Nuclear power provides a domestic, stable energy source that can operate independently of volatile global markets. For many nations, this has become a strategic priority, reducing dependence on politically sensitive energy imports.

3. Advances in Technology

Modern innovations in nuclear technology are transforming the industry. Small Modular Reactors (SMRs) are leading the way as part of next-gen nuclear innovation, offering safer, more affordable, and flexible options for nuclear deployment. Unlike traditional large-scale reactors, SMRs can be built faster, scaled to specific energy needs, and deployed in remote or smaller markets.

Additionally, advances in reactor designs, such as Generation IV reactors and fusion research, promise to address longstanding concerns like waste management and safety. For example, some new designs can recycle spent fuel or run on alternative fuels, significantly reducing radioactive waste.

4. Public Perception Is Shifting

Public opinion on nuclear power is also changing. While the industry faced backlash after high-profile incidents like Chernobyl and Fukushima, increasing awareness of climate change and energy security is prompting many to reconsider, including renewed debates such as Germany's potential nuclear return in policy circles. A younger, climate-conscious generation views nuclear energy not as a relic of the past, but as an essential tool for a sustainable future.

5. Renewables Alone Are Not Enough

While renewable energy sources like solar and wind have grown exponentially, their intermittent nature remains a challenge. Energy storage technologies, such as batteries, have not yet matured enough to fully bridge the gap. Nuclear power, with its ability to provide constant, "baseload" energy, as France's fleet demonstrates in practice, serves as an ideal complement to variable renewables in a decarbonized energy mix.

6. Government Support and Investment

Policymakers are taking action to bolster the nuclear sector. Many countries are including nuclear energy in their clean energy plans, offering subsidies, grants, and streamlined regulations to accelerate its deployment. For instance, the United States has allocated billions of dollars to support advanced nuclear projects, the UK's green industrial revolution outlines support for upcoming reactor waves, while Europe has classified nuclear power as "sustainable" under its green taxonomy.

7. Global Energy Demand Is Growing

As populations and economies grow, so does the demand for electricity. Developing nations, in particular, are seeking energy solutions that can support industrialization while limiting environmental impact. Nuclear energy is being embraced as a way to meet these dual objectives, especially in regions with limited access to consistent renewable energy resources.

Challenges Ahead

Despite its potential, nuclear energy is not without its challenges. High upfront costs, lengthy construction timelines, and public concerns over safety and waste remain significant hurdles. The industry will need to address these issues while continuing to innovate and build public trust.

Nuclear power's resurgence is driven by its unique ability to tackle some of the most pressing challenges of our time: climate change, energy security, and the growing demand for electricity. With advances in technology, changing perceptions, and robust policy support, nuclear energy is poised to play a critical role in the global transition to a sustainable and secure energy future.

In a world increasingly shaped by the need for clean and reliable power, nuclear energy has once again become a hot topic—and for good reason.

UK EV Per-Mile Taxes are reshaping road pricing and vehicle taxation for electric cars, raising fairness concerns, climate policy questions, and funding needs for infrastructure and charging networks across the country.

Key Points

They are per-mile road charges on EVs to fund infrastructure, raising fairness, emissions, and vehicle taxation concerns.

✅ Propose tax relief or credits for EV owners

✅ Consider emission-based road user charging

✅ Invest in charging networks and road infrastructure

As the UK continues its push towards a greener future with increased adoption of electric vehicles (EVs) and surging EV interest during supply disruptions, a growing number of electric car drivers are voicing their frustration over the current tax system. The debate centers around the per-mile vehicle taxes that are being proposed and implemented, which many argue are unfairly burdensome on EV owners. This issue has sparked a broader campaign advocating for a more equitable approach to vehicle taxation, one that reflects the evolving landscape of transportation and environmental policy.

Rising Costs for Electric Car Owners

Electric vehicles have been hailed as a crucial component in the UK’s strategy to reduce carbon emissions and combat climate change. Government incentives, such as grants for EV purchases and tax breaks, have been instrumental in encouraging the shift from petrol and diesel cars to cleaner alternatives, even as affordability concerns persist among many UK consumers. However, as the number of electric vehicles on the road grows, the financial dynamics of vehicle taxation are coming under scrutiny.

One of the key issues is the introduction and increase of per-mile vehicle taxes. While these taxes are designed to account for road usage and infrastructure costs, they have been met with resistance from EV drivers who argue that they are being disproportionately affected. Unlike traditional combustion engine vehicles, electric cars typically have lower running costs compared to petrol or diesel models and, in many cases, benefit from lower or zero emissions. Yet, the current tax system does not always reflect these advantages.

The Taxation Debate

The crux of the debate lies in how vehicle taxes are structured and implemented. Per-mile taxes are intended to ensure that all road users contribute fairly to the maintenance of transport infrastructure. However, the implementation of such taxes has raised concerns about fairness and affordability, particularly for those who have invested heavily in electric vehicles.

Critics argue that per-mile taxes do not adequately take into account the environmental benefits of driving an electric car, noting that the net impact depends on the electricity generation mix in each market. While EV owners are contributing to a cleaner environment by reducing emissions, they are also facing higher taxes that could undermine the financial benefits of their greener choice. This has led to calls for a reassessment of the tax system to ensure that it aligns with the UK’s climate goals and provides a fair deal for electric vehicle drivers.

Campaigns for Fairer Taxation

In response to these concerns, several advocacy groups and individual EV owners have launched campaigns calling for a more balanced approach to vehicle taxation. These campaigns emphasize the need for a system that supports the transition to electric vehicles and recognizes their role in reducing environmental impact, drawing on ambitious EV targets abroad as useful benchmarks.

Key proposals from these campaigns include:

1. Tax Relief for EV Owners: Advocates suggest providing targeted tax relief for electric vehicle owners to offset the costs of per-mile taxes. This could include subsidies or tax credits that acknowledge the environmental benefits of EVs and help to make up for higher road usage fees.

2. Emission-Based Taxation: An alternative approach is to design vehicle taxes based on emissions rather than mileage. This system would ensure that those driving high-emission vehicles contribute more to road maintenance, while EV owners, who are already reducing emissions, are not penalized.

3. Infrastructure Investments: Campaigners also call for increased investments in infrastructure that supports electric vehicles, such as charging networks and proper grid management practices that balance load. This would help to address concerns about the adequacy of current road maintenance and support the growing number of EVs on the road.

Government Response and Future Directions

The UK government faces the challenge of balancing revenue needs with environmental goals. While there is recognition of the need to update the tax system in light of increasing EV adoption, there is also a focus on ensuring that any changes are equitable and do not disincentivize the shift towards cleaner vehicles, while considering whether the UK grid can handle additional EV demand reliably.

Discussions are ongoing about how to best implement changes that address the concerns of electric vehicle owners while ensuring that the transportation infrastructure remains adequately funded. The outcome of these discussions will be critical in shaping the future of vehicle taxation in the UK and supporting the country’s broader environmental objectives.

Conclusion

As electric vehicle adoption continues to rise in the UK, the debate over vehicle taxation becomes increasingly important. The campaign for fairer per-mile taxes highlights the need for a tax system that supports the transition to cleaner transportation while also being fair to those who have made environmentally conscious choices. Balancing these factors will be key to achieving the UK’s climate goals and ensuring that all road users contribute equitably to the maintenance of transport infrastructure. The ongoing dialogue and policy adjustments will play a crucial role in shaping a sustainable and just future for transportation in the UK.

Bruce Power Life-Extension Programme advances Ontario nuclear capacity through CANDU Major Component Replacement, reliable operation milestones, supply chain retooling for COVID-19 recovery, PPE production, ventilator projects, and medical isotope supply security.

Key Points

A program to refurbish CANDU reactors, extend asset life, and mobilize Ontario nuclear supply chain and isotopes.

✅ Extends CANDU units via Major Component Replacement

✅ Supports COVID-19 recovery with PPE and ventilator projects

✅ Boosts Ontario energy reliability and medical isotopes

Canada’s Bruce Power said on 1 May that unit 1 at the Bruce nuclear power plant had set a record of 624 consecutive days of reliable operation – the longest since it was returned to service in 2012.

It exceeded Bruce 8’s run of 623 consecutive days between May 2016 and February 2018. Bruce 1, a Candu reactor, was put into service in 1977. It was shut down and mothballed by the former Ontario Hydro in 1997, and was refurbished and returned to service in 2012 by Bruce Power.

Bruce units 3 and 4 were restarted in 2003 and 2004. They are part of Bruce Power’s Life-Extension Programme, and future planning such as Bruce C project exploration continues across the fleet, with units 3 and 4 to undergo Major Component Replacement (MCR) Projects from 2023-28, adding about 30 years of life to the reactors.

The refurbishment of Bruce 6 has begun and will be followed by MCR Unit 3 which is scheduled to begin in 2023. Nuclear power accounts for more than 60% of Ontario’s supply, with Bruce Power providing more than 30%   of the province’s electricity.

Set up of Covid recovery council
On 30 April, Bruce Power announced the establishment of the Bruce Power Retooling and Economic Recovery Council to leverage the province’s nuclear supply chain to support Ontario’s fight against Covid-19 and to help aid economic recovery.

Bruce Power’s life extension programme is Canada’s second largest infrastructure project and largest private sector infrastructure programme. It is creating 22,000 direct and indirect jobs, delivering economic benefits that are expected to contribute $4 billion to Ontario’s GDP and $8-$11 billion to Canada’s gross domestic product (GDP), Bruce Power said.

“With 90% of the investment in manufactured goods and services coming from 480 companies in Ontario and other provinces, including recent manufacturing contracts with key suppliers, we can harness these capabilities in the fight against Covid-19, and help drive our economic recovery,” the company said.

“An innovative and dynamic nuclear supply chain is more important than ever in meeting this new challenge while successfully implementing our mission of providing clean, reliable, flexible, low-cost nuclear energy and a global supply of medical isotopes,” said Bruce Power president and CEO Mike Rencheck. “We are mobilising a great team with our extended supply chain, which spans the province, to assist in the fight against Covid-19 and to help drive our economic recovery in the future.”

Greg Rickford, the Minister of Energy, Mines, Northern Development, and Minister of Indigenous Affairs, said the launch of the council is consistent with Ontario’s focus to fight Covid-19 as a top priority and a look ahead to economic recovery, and initiatives like Pickering life extensions supporting long-term system reliability.

The creation of the Council was announced during a live event on Bruce Power's Facebook page, in which Rencheck was joined by Associate Minister of Energy Bill Walker and Rocco Rossi, the president and CEO of the Ontario Chamber of Commerce.

Walker reiterated the Government of Ontario’s commitment to nuclear power over the long term and to the life extension programme, including the Pickering B refurbishment as part of this strategy.

The Council, which will be formed for the duration of the pandemic and will include of all of Bruce Power’s Ontario-based suppliers, will focus on the continued retooling of the supply chain to meet front-line Covid-19 needs to contribute to the province’s economy recovery in the short, medium and long term.

New uses for nuclear medical applications will be explored, including isotopes for the sterilisation of medical equipment and long-term supply security.

The supply chain will be leveraged to support the health care sector through the rapid production of medical Personal Protection Equipment for front line-workers and large-scale PPE donations to communities as well as participation in pilot projects to make ventilators within the Bruce Power supply chain or help identify technology to better utilise existing ventilators;

“Buy Local” tools and approaches will be emphasised to ensure small businesses are utilised fully in communities where nuclear suppliers are located.

The production of hand sanitiser and other cleaning products will be facilitated for distribution to communities.

London Underground Power Outage 2025 disrupted Tube lines citywide, with a National Grid voltage dip causing service suspensions, delays, and station closures; TfL recovery efforts spotlight infrastructure resilience, contingency planning, and commuter safety communications.

Key Points

A citywide Tube disruption on May 12, 2025, triggered by a National Grid voltage dip, exposing resilience gaps.

✅ Bakerloo, Waterloo & City, Northern suspended; Jubilee disrupted.

✅ Cause: brief National Grid fault leading to a voltage dip.

✅ TfL focuses on recovery, communication, and resilience upgrades.

On May 12, 2025, a significant power outage disrupted the London Underground during the afternoon rush hour, affecting thousands of commuters across the city. The incident highlighted vulnerabilities in the city's transport infrastructure, echoing a morning outage in London reported earlier, and raised concerns about the resilience of urban utilities.

The Outage and Its Immediate Impact

The power failure occurred around 2:30 PM, leading to widespread service suspensions and delays on several key Tube lines. The Bakerloo and Waterloo & City lines were completely halted, while the Jubilee line experienced disruptions between London Bridge and Finchley Road. The Northern line was also suspended between Euston and Kennington, as well as south of Stockwell. Additionally, Elizabeth Line services between Abbey Wood and Paddington were suspended. Some stations were closed for safety reasons due to the lack of power.

Commuters faced severe delays, with many stranded in tunnels or on platforms. The lack of information and communication added to the confusion, as passengers were left uncertain about the cause and duration of the disruptions.

Cause of the Power Failure

Transport for London (TfL) attributed the outage to a brief fault in the National Grid's transmission network. Although the fault was resolved within seconds, it caused a voltage dip that affected local distribution networks, leading to the power loss in the Underground system.

The incident underscored the fragility of the city's transport infrastructure, particularly the aging electrical and signaling systems that are vulnerable to such faults, as well as weather-driven events like a major windstorm outage that can trigger cascading failures. While backup systems exist, their capacity to handle sudden disruptions remains a concern.

Broader Implications for Urban Infrastructure

This power outage is part of a broader pattern of infrastructure challenges facing London. In March 2025, a fire at an electrical substation in Hayes led to the closure of Heathrow Airport, affecting over 200,000 passengers, while similar disruptions at BWI Airport have underscored aviation vulnerabilities. These incidents have prompted discussions about the resilience of the UK's energy and transport networks.

Experts argue that aging infrastructure, coupled with increasing demand and climate-related stresses, poses significant risks to urban operations, as seen in a North Seattle outage and in Toronto storm-related outages that tested local grids. There is a growing call for investment in modernization and diversification of energy sources to ensure reliability and sustainability.

TfL's Response and Recovery Efforts

Following the outage, TfL worked swiftly to restore services. By 11 PM, all but one line had resumed operations, with only the Elizabeth Line continuing to experience severe delays. TfL officials acknowledged the inconvenience caused to passengers and pledged to investigate the incident thoroughly, similar to the Atlanta airport blackout inquiry conducted after a major outage, to prevent future occurrences.

In the aftermath, TfL emphasized the importance of clear communication with passengers during disruptions and committed to enhancing its contingency planning and infrastructure resilience.

Public Reaction and Ongoing Concerns

The power outage sparked frustration among commuters, many of whom took to social media to express their dissatisfaction, echoing sentiments during Houston's extended outage about communication gaps and delays. Some passengers reported being trapped in tunnels for extended periods without clear guidance from staff.

The incident has reignited debates about the adequacy of London's transport infrastructure and the need for comprehensive upgrades. While TfL has initiated reviews and improvement plans, the public remains concerned about the potential for future disruptions and the city's preparedness to handle them.

The May 12 power outage serves as a stark reminder of the vulnerabilities inherent in urban infrastructure. As London continues to grow and modernize, ensuring the resilience of its transport and energy networks will be crucial. This includes investing in modern technologies, enhancing communication systems, and developing robust contingency plans to mitigate the impact of future disruptions. For now, Londoners are left reflecting on the lessons learned from this incident and hoping for a more reliable and resilient transport system in the future.

Ontario Off-Peak Electricity Rate Relief extends 8.5 cents/kWh pricing 24/7 for residential, small business, and farm customers, covering Time-Of-Use and tiered plans to stabilize utility bills during COVID-19 Stay-at-Home measures across Ontario.

Key Points

A province-wide 8.5 cents/kWh price applied 24/7 until Feb 22, 2021 for TOU and tiered users to reduce electricity bills

✅ 8.5 cents/kWh, applied 24/7 through Feb 22, 2021

✅ Available to TOU and tiered OEB-regulated customers

✅ Automatic on bills for homes, small businesses, farms

The Ontario government is once again extending electricity rate relief for families, small businesses and farms to support those spending more time at home while the province maintains the Stay-at-Home Order in the majority of public health regions. The government will continue to hold electricity prices to the off-peak rate of 8.5 cents per kilowatt-hour, compared with higher peak rates elsewhere in the day, until February 22, 2021. This lower rate is available 24 hours per day, seven days a week for Time-Of-Use and tiered customers.

"We know staying at home means using more electricity during the day when electricity prices are higher, that's why we are once again extending the off-peak electricity rate to provide households, small businesses and farms with stable and predictable electricity bills when they need it most," said Greg Rickford, Minister of Energy, Northern Development and Mines, Minister of Indigenous Affairs. "We thank Ontarians for continuing to follow regional Stay-at-Home orders to help stop the spread of COVID-19."

The off-peak rate came into effect January 1, 2021, providing families, farms and small businesses with immediate electricity rate relief, and for industrial and commercial companies, stable pricing initiatives have provided additional certainty. The off-peak rate will now be extended until the end of day February 22, 2021, for a total of 53 days of emergency rate relief. During this period, and alongside temporary disconnect moratoriums for residential customers, the off-peak price will continue to be automatically applied to electricity bills of all residential, small business, and farm customers who pay regulated rates set by the Ontario Energy Board and get a bill from a utility.

"We extend our thanks to the Ontario Energy Board and local distribution companies across the province, including Hydro One, for implementing this extended emergency rate relief and supporting Ontarians as they continue to work and learn from home," said Bill Walker, Associate Minister of Energy.

Hornsea One Offshore Wind Farm delivers first power to the UK grid, scaling renewable energy with 1.2GW capacity, giant offshore turbines, and Yorkshire coast infrastructure to replace delayed nuclear and cut fossil fuel emissions.

Key Points

Hornsea One Offshore Wind Farm is a 1.2GW UK project delivering offshore renewable power to about 1 million homes.

✅ 174 turbines over 407 km2; Siemens Gamesa supply chain in the UK

✅ 1.2GW capacity can power ~1m homes; phases scale with 10MW+ turbines

✅ Supports UK grid, replaces delayed nuclear, cuts fossil generation

An offshore windfarm on the Yorkshire coast that will dwarf the world’s largest when completed is to supply its first power to the UK electricity grid this week, mirroring advances in tidal electricity projects delivering to the grid as well.

The Danish developer Ørsted, which has installed the first of 174 turbines at Hornsea One, said it was ready to step up its plans and fill the gap left by failed nuclear power schemes.

The size of the project takes the burgeoning offshore wind power sector to a new scale, on a par with conventional fossil fuel-fired power stations.

Hornsea One will cover 407 square kilometres, five times the size of the nearby city of Hull. At 1.2GW of capacity it will power 1m homes, making it about twice as powerful as today’s biggest offshore windfarm once it is completed in the second half of this year.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted, the world’s biggest offshore windfarm builder.

The power station is only the first of four planned in the area, with a green light and subsidies already awarded to a second stage due for completion in the early 2020s, and interest from Japanese utilities underscoring growing investor appetite.

The first two phases will use 7MW turbines, which are taller than London’s Gherkin building.

But the latter stages of the Hornsea development could use even more powerful, 10MW-plus turbines. Bigger turbines will capture more of the energy from the wind and should lower costs by reducing the number of foundations and amount of cabling firms need to put into the water, with developers noting that offshore wind can compete with gas in the U.S. as costs fall.

Henrik Poulsen, Ørsted’s chief executive, said he was in close dialogue with major manufacturers to use the new generation of turbines, some of which are expected to approach the height of the Shard in London, the tallest building in the EU.

The UK has a great wind resource and shallow enough seabed to exploit it, and could even “power most of Europe if it [the UK] went to the extreme with offshore”, he said.

Offshore windfarms could help ministers fill the low carbon power gap created by Hitachi and Toshiba scrapping nuclear plants, the executive suggested. “If nuclear should play less of a role than expected, I believe offshore wind can step up,” he said.

New nuclear projects in Europe had been “dramatically delayed and over budget”, he added, in comparison to “the strong track record for delivering offshore [wind]”.

The UK and Germany installed 85% of new offshore wind power capacity in the EU last year, according to industry data, with wind leading power across several markets. The average power rating of the turbines is getting bigger too, up 15% in 2018.

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull, part of a web of UK-based suppliers that has sprung up around the growing sector, such as Prysmian UK's land cables supporting grid connections.

Around half of the project’s transition pieces, the yellow part of the structure that connects the foundation to the tower, are made in Teeside. Many of the towers themselves are made by a firm in Campbeltown in the Scottish highlands. Altogether, about half of the components for the project are made in the UK.

Ørsted is not yet ready to bid for a share of a £60m pot of further offshore windfarm subsidies, to be auctioned by the government this summer, but expects the price to reach even more competitive levels than those seen in 2017.

Like other international energy companies, Ørsted has put in place contingency planning in event of a no-deal Brexit – but the hope is that will not come to pass. “We want a Brexit deal that will facilitate an orderly transition out of the union,” said Poulsen.
