Longest Lightning Flash Record confirmed by WMO: a 477.2-mile megaflash spanning Mississippi, Louisiana, and Texas, detected by satellite sensors, highlighting Great Plains supercell storms, lightning safety, and extreme weather monitoring advancements.

Key Points

It is the WMO-verified 477.2-mile megaflash across MS, LA, and TX, detected via satellites.

✅ Spanned 477.2 miles across Mississippi, Louisiana, and Texas

✅ Verified by WMO using space-based lightning detection

✅ Occurs in megaflash-prone regions like the U.S. Great Plains

An almost 500-mile long bolt of lightning that lit up the sky across three US states has set a new world record for longest flash, scientists have confirmed.

The lightning bolt, extended a total of 477.2 miles (768 km) and spread across Mississippi, Louisiana, and Texas.

The previous record was 440.6 miles (709 km) and recorded in Brazil in 2018.

Lightning rarely extends over 10 miles and usually lasts under a second, yet utilities plan for severe weather when building long-distance lines such as the TransWest Express transmission project to enhance reliability.

Another lightning flash recorded in 2020 - in Uruguay and Argentina - has also set a new record for duration at 17.1 seconds. The previous record was 16.7 seconds.

"These are extraordinary records from lightning flash events," Professor Randall Cerveny, the WMO's rapporteur of weather and climate extremes, said.

According to the WMO, both records took place in areas prone to intense storms that produce 'megaflashes', namely the Great Plains region of the United States and the La Plata basin of South America's southern cone, where utilities adapting to climate change is an increasing priority.

Professor Cerveny added that greater extremes are likely to exist and are likely to be recorded in the future thanks to advances in space-based lightning detection technology.

The WMO warned that lightning was a hazard and urged people in both regions and around the world to take caution during storms, which can lead to extensive disruptions like the Tennessee power outages reported after severe weather.

"These extremely large and long-duration lightning events were not isolated but happened during active thunderstorms," lightning specialist Ron Holle said in a WMO statement.

"Any time there is thunder heard, it is time to reach a lightning-safe place".

Previously accepted WMO 'lightning extremes' include a 1975 incident in which 21 people were killed by a single flash of a lightning as they huddled inside a tent in Zimbabwe, and modern events show how dangerous weather can also cut electricity for days, as with the Hong Kong typhoon outages that affected families.

In another incident, 469 people were killed when lightning struck the Egyptian town of Dronka in 1994, causing burning oil to flood the town, and major incidents can also disrupt infrastructure, as seen during the LA power outage following a substation fire.

The WMO notes that the only lightning-safe locations are "substantial" buildings with wiring and plumbing, and dedicated lightning protection training helps reinforce these guidelines, rather than structures such as bus stops or those found at beaches.

Fully enclosed metal-topped vehicles are also considered reliably safe, and regional storm safety tips offer additional guidance.

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."

Iran Bushehr Earthquake rattles southern province near the Bushehr nuclear power plant, USGS reports M5.1 at 38 km depth; seismic activity along major fault lines raises safety, damage, and monitoring concerns.

Key Points

A magnitude 5.1 quake near Bushehr nuclear plant at 38 km depth, with no damage reported, per USGS.

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

✅ Iran lies on major fault lines; quake risk is frequent

A magnitude 5 earthquake struck southern Iran early Friday near the Islamic Republic's only nuclear power plant. There were no immediate reports of damage or injuries as Iran continues combined-cycle conversions across its power sector.

The quake hit Iran's Bushehr province at 5:23 a.m., according to the U.S. Geological Survey. It put the magnitude at 5.1 and the depth of the earthquake at 38 kilometres (24 miles), in a province tied to efforts to transmit electricity to Europe in coming years.

Iranian state media did not immediately report on the quake. However, the Bushehr nuclear power plant was designed to withstand much stronger earthquakes, a notable consideration as Iraq plans nuclear power plants to address shortages.

A magnitude 5 earthquake can cause considerable damage, including power disruptions that have seen blackouts spark protests in some Iranian cities.

Iran sits on major fault lines and is prone to near-daily earthquakes, yet it remains a key player in regional power, with Iran-Iraq energy cooperation ongoing. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people, and today Iran supplies 40% of Iraq's electricity through cross-border power deals. Bam is near the Bushehr nuclear plant, which wasn’t damaged at that time, while more recently Iran finalized deals to rehabilitate Iraq's power grid to improve resilience.

UK Marine Energy and Climate Resilience can counter sea level rise and storm surge with tidal power, subsea turbines, heat pumps, and flood barriers, delivering renewable electricity, stability, and coastal protection for the United Kingdom.

Key Points

Integrated use of tidal power, barriers, and heat pumps to curb sea level rise, manage storms, and green the UK grid.

✅ Tidal bridges and subsea turbines enhance baseload renewables

✅ Integrated barriers cut storm surge and river flood risk

✅ Heat pumps and marine heat networks decarbonize coastal cities

IN concentrating on electrically driven cars, the UK’s new ten-point energy plans, and recent UK net zero policies, ignores the elephant in the room.

It fails to address the forecast six-metre sea level rise from global warming rapidly melting the Greenland ice sheet.

Rising sea levels and storm surge, combined with increasingly heavy rainfall swelling our rivers, threaten not only hundreds of coastal communities but also much unprotected strategic infrastructure, including electricity systems that need greater resilience.

New nuclear power stations proposed in this United Kingdom plan would produce radioactive waste requiring thousands of years to safely decay.

This is hardly the solution for the Green Energy future, or the broader global energy transition, that our overlooked marine energy resource could provide.

Sea defences and barrier design, built and integrated with subsea turbines and heat pumps, can deliver marine-driven heat and power to offset the costs, not only of new Thames Barriers, but also future Severn, Forth and other barrages, while reducing reliance on high-GWP gases such as SF6 in switchgear across the grid.

At the Pentland Firth, existing marine turbine power could be enhanced by turbines deployed from new tidal bridges to provide much of UK’s electricity needs, as nations chart an electricity future that replaces fossil fuels, from its estimated 60 gigawatt capability.

Energy from Bluemull Sound could likewise be harvested and exported or used to enhance development around UK’s new space station at Unst.

The 2021 Climate Change Summit gives Glasgow the platform to secure Scotland’s place in a true green, marine energy future and help build an electric planet for the long term.

We must not waste this opportunity.

THERE is no vaccine for climate change.

It is, of course, wonderful news that such progress is being made in the development of Covid-19 vaccines but there is a risk that, no matter how serious the Covid crisis is, it is distracting attention, political will and resources from the climate crisis, a much longer term and more devastating catastrophe.

They are intertwined. As climate and ecological systems change, vectors and pathogens migrate and disease spreads.

What lessons can be learned from one to apply to the other?

Prevention is better than cure. We need to urgently address the climate crisis, charting a path to net zero electricity by the middle of the century, to help prevent future pandemics.

We are only as safe as the most vulnerable. Covid immunisation will protect the most vulnerable; to protect against the effects of climate change we need to look far more deeply. Global challenges require systemic change.

Neither Covid or climate change respect national borders and, for both, we need to value and trust science and the scientific experts and separate them from political posturing.

BC Hydro Review Phase 2 Recommendations advance affordable electricity rates, clean energy adoption, electrification, and demand response, supporting heat pumps, EV charging, and low-income programs to cut emissions and meet CleanBC climate targets.

Key Points

Policies to keep rates affordable and accelerate clean electrification via heat pump, EV, and demand response incentives.

✅ Optional rates, heat pump and EV charging incentives

✅ Demand response via controllable devices lowers peak loads

✅ Expanded support for lower-income customers and affordability

The Province and BC Hydro have released recommendations from Phase 2 of the BC Hydro Review to keep rates affordable, including through a provincial rate freeze initiative that supported households, and encourage greater use of clean, renewable electricity to reduce emissions and achieve climate targets.

“Keeping life affordable for people is a key priority of our government,” said Bruce Ralston, Minister of Energy, Mines and Low Carbon Innovation. “Affordable electricity rates not only help British Columbians, they help ensure the price of electricity remains competitive with other forms of energy, supporting the transition away from fossil fuels to clean electricity in our homes and buildings, vehicles and businesses.”

While affordable rates have always been important to BC Hydro customers, amid proposals such as a modest rate increase under review, expectations are also changing as customers look to have more choice and control over their electricity use and opportunities to save money.

Guided by input from a panel of external energy industry experts, government and BC Hydro have developed recommendations under Phase 2 of the BC Hydro Review to reduce electricity costs for individuals and businesses, even as a 3.75% increase has been discussed, as envisioned by the CleanBC climate strategy. This is also in alignment with TogetherBC, the Province’s poverty reduction strategy, and its guiding principle of affordability.

“As we promote increased use of electricity in B.C. to achieve our climate targets, we need to continue to focus on keeping electricity rates affordable, especially for lower-income families,” said Nicholas Simons, Minister of Social Development and Poverty Reduction. “Through the BC Hydro Review, and continuing engagement with stakeholders and organizations to follow, we are committed to finding ways to keep rates affordable, so everyone has access to the benefits of B.C.’s clean, reliable electricity.”

Recommendations include having BC Hydro consider providing more support for lower-income BC Hydro customers, informed by a recent surplus report that highlighted funding opportunities. These include incentives and exploring optional rates for customers to adopt electric heat pumps, and facilitating customer adoption of controllable energy devices that provide BC Hydro the ability to offer incentives in return for helping to manage a customer’s electricity use. 

Electrification of B.C.’s economy helps customers reduce their carbon footprint and supports the Province’s CleanBC climate strategy, and is an important part of keeping electricity affordable even amid higher BC Hydro rates in recent periods. As more customers make the switch from fossil fuels to using clean electricity in their homes, vehicles and businesses, BC Hydro’s electricity sales will increase, providing more revenue that helps keep rates affordable for everyone.

“We’re making the transition to a cleaner future more affordable for people and businesses across British Columbia through our CleanBC plan,” said George Heyman, Minister of Environment and Climate Change Strategy. “By working with BC Hydro and other partners, we’re making sure everyone has access to clean, affordable electricity to power technologies like high-efficiency heat pumps and electric vehicles that will reduce harmful pollution and improve our homes, buildings and communities.”

Chris O’Riley, president and CEO, BC Hydro, said: “Given the impact of COVID-19 on British Columbians, affordability is more important than ever. That’s why we are committed to continuing to keep rates affordable and offering customers more options that allow them to save on their bills while using clean electricity.”

In July 2021, the Province announced a first set of recommendations from Phase 2 of the BC Hydro Review amid a 3% rate increase approved by regulators. The next announcement from Phase 2 will include recommendations to increase the number of electric vehicles on the road.

In addition, as part of the Draft Action Plan to advance the Declaration on the Rights of Indigenous Peoples Act, the Province is proposing to engage with Indigenous peoples to identify and support new clean energy opportunities related to CleanBC, the BC Hydro Review and the British Columbia Utilities Commission Indigenous Utilities Regulation Inquiry, and to consider lessons from Ontario's hydro policy experiences as appropriate.

B.C. is the cleanest electricity-generation jurisdiction in western North America, with an average of 98% of its electricity generation coming from clean or renewable resources.

Poland Offshore Wind Energy accelerates as PGE exits nuclear leadership, PKN Orlen steps in, and Baltic Sea projects expand to cut coal reliance, meet EU emissions goals, attract investors, and bridge the power capacity gap.

Key Points

A shift from coal and nuclear to Baltic offshore wind to add capacity, cut EU emissions, and attract investment.

✅ PGE drops lead in nuclear; pivots $10bn to offshore wind.

✅ PKN Orlen may assume nuclear role; projects await approval.

✅ 6 GW offshore could add 60b zlotys and 77k jobs by 2030.

PGE, Poland’s biggest power group has decided to abandon a role in building the country’s first nuclear power plant and will instead focus investment on offshore wind energy.

Reuters reports state-run refiner PKN Orlen (PKN.WA) could take on PGE’s role, while the latter announces a $10bn offshore wind power project.

Both moves into renewables and nuclear represent a major change in Polish energy policy, diversifying away from the country’s traditional coal-fired power base, as regional efforts like the North Sea wind farms initiative expand, in a bid to fill an electricity shortfall and meet EU emission standards.

An unnamed source told the news agency, PGE could not fund both projects and cheap technology had swung the decision in favour of wind, with offshore wind competing with gas in some markets. PGE could still play a smaller role in the nuclear project which has been delayed and still needs government approval.

A proposed law is currently before the Polish parliament aiming at facilitating easy construction of wind turbines, mindful of Germany’s grid expansion challenges that have hindered rollout.

If the law is passed, as expected, several other wind farm projects could also proceed.

Polenergia has said it would like to build a wind farm in the Baltic by 2022. PKN Orlen is also considering building one.

PGE said in March that it wants to build offshore windfarms with a capacity of 2.5 gigawatts (GW) by 2030.

Analysts and investors say that offshore wind farms are the easiest and fastest way for Poland to fill the expected capacity gap from coal, with examples like the largest UK offshore wind farm coming online underscoring momentum, and reduce CO2 emissions in line with EU’s 2030 targets as Poland seeks improved ties with Brussels.

The decision to open up the offshore power industry could also draw in investors, as shown by Japanese utilities’ UK offshore investment attracting cross-border capital. Statoil said in April it would join Polenergia’s offshore project which has drawn interest from other international wind companies. “

The Polish Wind Energy Association (PWEA) estimates that offshore windfarms with a total capacity of 6 GW would help create around 77,000 new jobs and add around 60 billion zlotys to economic growth.
