A searing stretch of hot, dry weather, coupled with rising water use, could prolong a drought that's far from over.

Forecasters said that the Charlotte area faces at least another week of temperatures in the 90s. Highs normally reach only the mid-80s this time of year. The June 5 high reached 95 degrees at Charlotte/Douglas International Airport, the warmest reading so far this year.

Highs were in the middle to upper 90s today across the Piedmont and South Carolina.

Highs for the next eight days are forecast between 96 a d 98 degrees. Forecasters see little or no chance of rainfall in the area through at least June 11. Some computer models show the heat wave continuing for at least 10 days.

A heat advisory was issued June 6 in the Sandhills, where the heat index - a combination of heat and dewpoint temperatures - is forecast to reach 105 degrees. Anson, Richmond and Scotland counties of North Carolina and Chesterfield County in South Carolina are included in that advisory.

Heat index readings climbed above 100 the past few days. Forecasters also are predicting Code Orange ozone levels. Code Orange ozone levels are potentially unhealthy for asthmatics, children and seniors.

Charlotte-Mecklenburg Utilities customers promptly broke June's daily conservation goal by pumping 128 million gallons on Sunday. The surge was predictable as gardeners water blooming shrubs and vegetable patches, said conservation coordinator Maeneen Klein.

Mandatory water restrictions allow lawn watering only one day a week, but drip irrigation and hoses can be used anytime. "As long as people are following the rules and putting water where it's needed the most, we think it's a sustainable practice," she said.

Klein credits customers for taking conservation to heart. This month's 115 million-gallon-a-day goal compares to the 141 million gallons Charlotteans averaged last June, before restrictions took hold.

A drought-advisory group for the Catawba River basin, which in early April recommended utilities resume limited lawn irrigation, will review conditions again on June 25. The roots of this drought trace to May 2007, the first in a string of dry months that lasted until December. Conditions improved through the winter and spring but turned dry again last month.

Mecklenburg and its neighbors are among 28 N.C. counties still in extreme drought. Only 11 counties had been that dry in late April. Charlotte's rainfall deficit since January is 3.6 inches, but the past 12 months have been the driest June-to-June on record in the southern Piedmont.

Still, federal forecasters expect the drought in the Carolinas' western halves to improve through August. Three-month forecasts predict neither unusually high nor low summer temperatures and rainfall. The region's major water supplies are also faring better than they did last year.

As the drought deepened, Duke Energy resisted estimating how many days' water was left in its Catawba reservoirs, saying projections would probably be wrong. Some critics complained that local utilities, guided by the newly created drought group, were too slow to restrict water use. This year lakes on both the Catawba, Charlotte's water source, and the Yadkin River to the east are near or above targeted levels.

To save water, Duke began cutting back use of its hydroelectric plants last summer, generating 58 percent less hydro power this January through May than in the same period last year. Duke could also draw down its largest reservoir, Lake Norman, by nearly 3 extra feet if needed this year because of changes to the cooling-water piping at its McGuire nuclear plant.

But streams that feed the Catawba lakes are at only 46 percent of their long-term averages, compared to 89 percent a year ago. Groundwater still hasn't recovered. Rising temperatures also mean more water lost to evaporation: up to 300 million gallons from the Catawba reservoirs on a single hot day.

"Conservation is just as important as it was last year," said Duke spokeswoman Marilyn Lineberger.

Opinion: Fossil-fuel workers ready to support energy transition

Canada Net-Zero Transition unites energy workers, R&D, and clean tech to decarbonize steel and cement with hydrogen, scale renewables, and build hybrid storage, delivering a just transition that strengthens communities and the economy.

 

Key Points

A national plan to reach net-zero by 2050 via renewables, hydrogen, decarbonization, and a just transition for workers.

✅ Hydrogen for steel and cement decarbonization

✅ Hybrid energy storage and clean tech R&D

✅ Just transition pathways for energy workers

 

Except for an isolated pocket of skeptics, there is now an almost universal acceptance that climate change is a global emergency that demands immediate and far-reaching action to defend our home and future generations. Yet in Canada we remain largely focused on how the crisis divides us rather than on the potential for it to unite us, despite nationwide progress in electricity decarbonization efforts.

It’s not a case of fossil-fuel industry workers versus the rest, or Alberta versus British Columbia where bridging the electricity gap could strengthen cooperation. We are all in this together. The challenge now is how to move forward in a way that leaves no one behind.

The fossil fuel industry has been — and continues to be — a key driver of Canada’s economy. Both of us had successful careers in the energy sector, but realized, along with an increasing number of energy workers, that the transition we need to cope with climate change could not be accomplished solely from within the industry.

Even as resource companies innovate to significantly reduce the carbon burden of each barrel, the total emission of greenhouse gases from all sources continues to rise. We must seize the opportunity to harness this innovative potential in alternative and complementary ways, mobilizing research and development, for example, to power carbon-intensive steelmaking and cement manufacture from hydrogen or to advance hybrid energy storage systems and decarbonizing Canada's electricity grid strategies — the potential for cross-over technology is immense.

The bottom line is inescapable: we must reach net-zero emissions by 2050 in order to prevent runaway global warming, which is why we launched Iron & Earth in 2016. Led by oilsands workers committed to increasingly incorporating renewable energy projects into our work scope, our non-partisan membership now includes a range of industrial trades and professions who share a vision for a sustainable energy future for Canada — one that would ensure the health and equity of workers, our families, communities, the economy, and the environment.

India’s Kakrapur 3 achieves criticality

Kakrapar Unit 3 700MWe PHWR achieved first criticality, showcasing indigenously designed nuclear power, NPCIL operations, Make in India manufacturing, advanced safety systems, grid integration, and closed-fuel-cycle strategy for India's expansion of pressurised heavy water reactors.

 

Key Points

India's first indigenous 700MWe PHWR at Kakrapar reached criticality, advancing NPCIL's Make in India nuclear power.

✅ First indigenous 700MWe PHWR achieves criticality

✅ NPCIL-built, Make in India components and contractors

✅ Advanced safety: passive decay heat removal, containment spray

 

Unit 3 of India’s Kakrapar nuclear plant in Gujarat achieved criticality on 22 July, as milestones at nuclear projects worldwide continue to be reached. It is India’s first indigenously designed 700MWe pressurised heavy water reactor (PHWR) to achieve this milestone.

Prime Minister Narendra Modi congratulated nuclear scientists, saying the reactor is a shining example of the 'Make in India' campaign and of the government's steps to get nuclear back on track in recent years, and a trailblazer for many such future achievements. 

India developed its own nuclear power generation technology as it faced sanctions from the international community following its first nuclear weapons test in in 1974. It has not signed the Nuclear Non-Proliferation Treaty, while China's nuclear energy development is on a steady track according to experts. India has developed a three-stage nuclear programme based on a closed-fuel cycle, where the used fuel of one stage is reprocessed to produce fuel for the next stage.

Kakrapar 3 was developed and is operated by state-owned Nuclear Power Corporation of India Ltd (NPCIL), while in Europe KHNP considered for a Bulgarian project as countries weigh options. The first two units are 220MWe PHWRs commissioned in 1993 and 1995. NPCIL said in a statement that the components and equipment for Kakrapur 3 were “manufactured by lndian industries and the construction and erection was undertaken by various lndian contractors”.

The 700MWe PHWRs have advanced safety features such as steel lined inner containment, a passive decay heat removal system, a containment spray system, hydrogen management systems etc, the statement added.

Fuel loading was completed by mid-March, a crucial step in Abu Dhabi during its commissioning as well. “Thereafter, many tests and procedures were carried out during the lockdown period following all COVlD-19 guidelines.”

“As a next step, various experiments / tests will be conducted and power will be increased progressively, a path also followed by Barakah Unit 1 reaching 100% power before commercial operations.” Kakrapur 3 will be connected to the western grid and will be India’s 23rd nuclear power reactor.

Kakrapur 3 “is the front runner in a series of 16 indigenous 700MWe PHWRs which have been accorded administrative approval and financial sanction by the government and are at various stages of implementation”. Five similar units are under construction at Kakarapur 4, Rajasthan 7&8 and Gorakhpur1&2.

DAE said in January 2019 that India planned to put 21 new nuclear units with a combined generating capacity of 15,700MWe into operation by 2031, including ten indigenously designed PHWRs, while Bangladesh develops nuclear power with IAEA assistance.

UK price cap on household energy bills expected to cost 89bn

UK Energy Price Guarantee Cost forecasts from Cornwall Insight suggest an £89bn bill, tied to wholesale gas prices, OBR projections, and fiscal policy, to shield households amid the cost of living crisis.

 

Key Points

It is the projected government spend to cap household bills, driven by wholesale gas prices and OBR market forecasts.

✅ Base case: £89bn over two years, per Cornwall Insight

✅ Range: £72bn to £140bn, volatile wholesale gas costs

✅ Excludes 6-month business support estimated at £22bn-£48bn

 

Liz Truss’s intervention to freeze energy prices for households for two years is expected to cost the government £89bn, according to the first major costing of the policy by the sector’s leading consultancy.

The analysis from Cornwall Insight, seen exclusively by the Guardian, shows the prime minister’s plan to tackle the cost of living crisis could cost as much as £140bn in a worst-case scenario.

Truss announced in early September that the average annual bill for a typical household would be capped at £2,500 to protect consumers from the intensifying cost of living crisis amid high winter energy costs and a scheduled 80% rise in the cap to £3,549.

The ultimate cost of the policy is uncertain as it is highly dependent on the wholesale cost of gas, including UK natural gas prices which have soared since Russia’s invasion of Ukraine put a squeeze on already-volatile international markets. Ballpark projections had put the cost anywhere from £100bn to £150bn.

The Office for Budget Responsibility is expected to give its forecast for the bill when it provides its independent assessment of Kwasi Kwarteng’s medium-term fiscal plan, which the chancellor said on Tuesday would still happen on 23 November despite previous reports that it would be brought forward.

Cornwall Insight analysed projections of wholesale market moves to cost the intervention. In its base case scenario, analysts expect the policy to cost £89bn. That assumes the cost of supporting each household would be just over £1,000 in the first year, and about £2,000 in the second year.

The study’s authors said the wholesale price of gas would be influenced by energy demand, the severity of weather, “geo-political uncertainty” and prices for liquified natural gas as Europe seeks to refill storage facilities, which countries have rushed to fill up this winter but which could be relatively empty by next spring.

In the best-case outcome, the policy would cost £72bn, with some projections pointing to a 16% decrease in energy bills in April for households, while the “extreme high” outlook would see the government shell out £140bn to protect 29m UK households.

Gas prices are expected to push even higher if the Kremlin decides to completely cut off Russian gas exports into Europe.

Cornwall Insight’s projection does not include a separate six-month initiative to cap costs for companies, charities and public sector organisations, which is forecast to cost £22bn to £48bn.

The consultancy’s chief executive, Gareth Miller, said the £70bn range in its forecasts reflected “a febrile wholesale market continuing to be beset by geopolitical instability, sensitivity to demand, weather and infrastructure resilience”.

He said: “Fortune befriends the bold, but it also favours the prepared. The large uncertainties around commodity markets over the next two years means that the government could get lucky with costs coming out at the low end of the range, but the opposite could also be true.

“In each case, the government may find itself passengers to circumstances outside its control, having made policy that is a hostage to surprises, events and volatile factors. That’s a difficult position to be in.”

The government has faced criticism, as some British MPs urge tighter limits on prices, that the policy is effectively a “blank cheque” and is not targeted at the most vulnerable in society.

Concerns over how Truss and Kwarteng intend to fund a series of measures, including the price guarantee, have spooked financial markets.

The EU, which has outlined possible gas price cap strategies in recent proposals, said last week it planned to cap the revenues of low-carbon electricity generators at €180 a megawatt hour, which is less than half current market prices. Truss has so far resisted calls to extend a levy on North Sea oil and gas operators to electricity generators, who have benefited from a link between gas and electricity prices in Britain.

Truss hopes to strike voluntary long-term deals with generators including Centrica and EDF, alongside the government’s Energy Security Bill measures, to bring down wholesale prices.

The Financial Times reported on Tuesday that the government has threatened companies with legislation to cap their revenues if voluntary deals cannot be agreed.

Shocking scam: fraudster pretending to be from BC Hydro attempts to extort business

BC Hydro Bitcoin Scam targets small businesses with utility impersonation, call spoofing, and disconnection threats, demanding prepaid cards, cash cards, or bitcoin. Learn payment policies and key warning signs to avoid costly power shutoffs.

 

Key Points

A phone fraud where impostors threaten power disconnection and demand immediate payment via bitcoin or prepaid cards.

✅ Demands bitcoin, cash cards, or prepaid credit within minutes

✅ Uses caller ID spoofing and utility impersonation tactics

✅ BC Hydro never takes bitcoin or prepaid cards for bills

 

'I've gotta give him very high marks for being a good scammer,' says almost-fooled business owner

It's an old scam with a new twist.

Fraudsters pretending to be BC Hydro representatives are threatening to disconnect small business owners' power, mirroring Toronto Hydro scam warnings recently, unless they send in cash cards, prepaid credit cards or even bitcoin right away.

Colin Mackintosh, owner of Trans National Art in Langley, B.C., said he almost was fooled by one such scammer.

It was just before quitting time on Thursday at his shop when he got an unpleasant phone call.

"The phone rings. My partner hands me the phone and this fellow says to me that he's outside, he works with BC Hydro and he has a disconnect notice," Mackintosh said.

The caller, Mackintosh said, claimed that if an immediate payment wasn't made they'd cut off the company's power.

'Very well done'

BC Hydro says the scam has been around for a while, and amid commercial power use during COVID-19 in B.C., demanding payment in bitcoin is a new wrinkle.

Fraudsters mostly target small businesses because losing their power for a day or two would be a huge financial hit, a spokesperson said.

Mackintosh said the scammer knew all about the business. His number even showed up as BC Hydro on the call display, and the utility has faced scrutiny in a regulator report unrelated to such scams.

"He had all the answers to every question I seemed to have for him.  Very professional. Very well done. I've gotta give him very high marks for being a good scammer," Mackintosh said.

The caller demanded Mackintosh make an immediate payment at the nearest BC Hydro kiosk. Mackintosh was directed to drive to a certain address to make the payment.

He was ready to pay hundreds of dollars but when he got to the address, there was no kiosk: just a tire shop and inside something that looked like a cash machine but was actually a bitcoin ATM.

"At the very top of it, in little letters, it said 'Bit Coin,'" Mackintosh said. "As soon as I saw those two words, I told him in two expressive words what I thought of him and I hung up the phone."

 

Scam increasing

BC Hydro spokesperson Mora Scott said fraudsters target small businesses because their livelihoods depend on power, and customers face pressures highlighted in a deferred costs report as well.

"Fraudsters will reach out to our customers pretending to be B.C. Hydro representatives," said Scott.

"They'll demand an immediate payment or they'll disconnect their power. This did start to surface around 2015 but we have seen an increase recently."

Scott said that BC Hydro will never ask for banking information over the phone and does not accept cash card, prepaid credit cards or bitcoin as payment, and customers can consult BC Hydro bill relief for legitimate assistance.

840 million people have no electricity – World Bank must fund more energy projects

World Bank Energy Policy debates financing for coal, oil, gas, and renewables to fight energy poverty, expand grid reliability, ensure baseload power, and balance climate goals with development finance for affordable, reliable electricity access.

 

Key Points

It outlines the bank's stance on financing fossil fuels and renewables to expand affordable, reliable electricity.

✅ Focus on energy access, baseload reliability, and poverty alleviation

✅ Debate over coal, gas, and renewables in development finance

✅ Geopolitics: China and Russia fill funding gaps, raising risks

 

Why isn’t the World Bank using all available energy resources in its global efforts to fight poverty? That’s the question I’ve asked World Bank President David Malpass. Nearly two years ago, the multilateral development bank decided to stop supporting critical coal, oil and gas projects that help people in developing countries escape poverty.

Along with 11 other senators, and as a member who votes on whether to give U.S. taxpayer dollars to the World Bank, I am pressing the bank to lift these restrictions. Developing countries desperately need access to a steady supply of affordable, reliable clean electricity to support economic growth.

The World Bank has pulled funding for critical electricity projects in poor countries, including high-efficiency power stations that are fueled by coal, even as efforts to revitalize coal communities with clean energy have grown.

Despite Kosovo having the world’s fifth-largest reserves of coal, the bank announced it would only support new energy projects from renewable sources going forward. Kosovo’s Minister of Economic Development Valdrin Lluka responded: “We don’t have the luxury to do such experiments in a poor country such as Kosovo. … It is in our national security interest to secure base energy inside our country.”

The World Bank’s misguided move comes as 840 million people worldwide are living without electricity, including 70 percent of sub-Saharan Africa, and as the fall in global energy investment may lead to shortages.

Even more troubling, nearly 3 billion people in developing countries rely on fuels like wood and other biomass for cooking and home heating, resulting in serious health problems and premature deaths, and the pandemic saw widespread electricity shut-offs that deepened energy insecurity. In 2016, household smoke killed an estimated 2.6 million people.

The World Bank’s mission is to lift people out of poverty. The bank is now compromising that mission in favor of a political agenda targeting certain energy sources.

With the World Bank blocking financing to affordable and reliable energy projects, Russia and China are stepping up their investments in order to gain geopolitical leverage.

President Vladimir Putin is pursuing Russian oil and gas projects in Mozambique, Gabon, and Angola. China’s Belt and Road Initiative is supporting traditional energy resources, with 36 percent of its power projects from 2014 to 2017 involving coal. South Africa had to turn to the China Development Bank to fund its $1.5 billion coal-fired power plant.

There are real risks for countries partnering with China and Russia on these projects. Developing countries are facing what some are calling China’s “debt trap” diplomacy. These nations have also raised concerns over safety compliance, unfair business practices, and labor standards.

As the bank’s largest contributor, the United States has a duty to make sure U.S. taxpayer dollars are used wisely and effectively. Every U.S. dollar at the World Bank should make a difference for people in the developing world.

My colleagues and I have asked the bank to pursue an all-of-the-above energy strategy as it strives to achieve its mission to end extreme poverty and promote shared prosperity. We will take the bank’s response into account during the congressional appropriations process.

The United States is a top global energy producer. And yet Democrats running for president are pursuing anti-energy policies that would hurt not only the United States but the entire world, with implications for U.S. national security as well.

Utilizing our abundant energy resources has fueled an American energy renaissance and a booming U.S. economy, even as disruptions in coal and nuclear have strained the grid, with millions of new jobs and higher wages.

People who are struggling to survive and thrive in developing countries deserve the same opportunity to access affordable and reliable sources of power.

As Microsoft founder and global philanthropist Bill Gates has noted of renewables: "Many people experiencing energy poverty live in areas without access to the kind of grids that are needed to make those technologies cheap and reliable enough to replace fossil fuels."

Ultimately, there is a role for all sources of energy to help countries alleviate poverty and improve the education, health and wellbeing of their people.

The solution to ending energy poverty does not lie in limiting options, but in using all available options. The World Bank must recommit to ending extreme poverty by helping countries use all of the world’s abundant energy resources. Let’s end energy poverty now.

A tenth of all electricity is lost in the grid - superconducting cables can help

High-Temperature Superconducting Cables enable lossless, high-voltage, underground transmission for grid modernization, linking renewable energy to cities with liquid nitrogen cooling, boosting efficiency, cutting emissions, reducing land use, and improving resilience against disasters and extreme weather.

 

Key Points

Liquid-nitrogen-cooled power cables delivering electricity with near-zero losses, lower voltage, and greater resilience.

✅ Near-lossless transmission links renewables to cities efficiently

✅ Operate at lower voltage, reducing substation size and cost

✅ Underground, compact, and resilient to extreme weather events

 

For most of us, transmitting power is an invisible part of modern life. You flick the switch and the light goes on.

But the way we transport electricity is vital. For us to quit fossil fuels, we will need a better grid, with macrogrid planning connecting renewable energy in the regions with cities.

Electricity grids are big, complex systems. Building new high-voltage transmission lines often spurs backlash from communities, as seen in Hydro-Que9bec power line opposition over aesthetics and land use, worried about the visual impact of the towers. And our 20th century grid loses around 10% of the power generated as heat.

One solution? Use superconducting cables for key sections of the grid. A single 17-centimeter cable can carry the entire output of several nuclear plants. Cities and regions around the world have done this to cut emissions, increase efficiency, protect key infrastructure against disasters and run powerlines underground. As Australia prepares to modernize its grid, it should follow suit with smarter electricity infrastructure initiatives seen elsewhere. It's a once-in-a-generation opportunity.


What's wrong with our tried-and-true technology?
Plenty.

The main advantage of high voltage transmission lines is they're relatively cheap.

But cheap to build comes with hidden costs later. A survey of 140 countries found the electricity currently wasted in transmission accounts for a staggering half-billion tons of carbon dioxide—each year.

These unnecessary emissions are higher than the exhaust from all the world's trucks, or from all the methane burned off at oil rigs.

Inefficient power transmission also means countries have to build extra power plants to compensate for losses on the grid.

Labor has pledged A$20 billion to make the grid ready for clean energy, and international moves such as US-Canada cross-border approvals show the scale of ambition needed. This includes an extra 10,000 kilometers of transmission lines. But what type of lines? At present, the plans are for the conventional high voltage overhead cables you see dotting the countryside.

System planning by Australia's energy market operator shows many grid-modernizing projects will use last century's technologies, the conventional high voltage overhead cables, even as Europe's HVDC expansion gathers pace across its network. If these plans proceed without considering superconductors, it will be a huge missed opportunity.


How could superconducting cables help?
Superconduction is where electrons can flow without resistance or loss. Built into power cables, it holds out the promise of lossless electricity transfer, over both long and short distances. That's important, given Australia's remarkable wind and solar resources are often located far from energy users in the cities.

High voltage superconducting cables would allow us to deliver power with minimal losses from heat or electrical resistance and with footprints at least 100 times smaller than a conventional copper cable for the same power output.

And they are far more resilient to disasters and extreme weather, as they are located underground.

Even more important, a typical superconducting cable can deliver the same or greater power at a much lower voltage than a conventional transmission cable. That means the space needed for transformers and grid connections falls from the size of a large gym to only a double garage.

Bringing these technologies into our power grid offers social, environmental, commercial and efficiency dividends.

Unfortunately, while superconductors are commonplace in Australia's medical community (where they are routinely used in MRI machines and diagnostic instruments) they have not yet found their home in our power sector.

One reason is that superconductors must be cooled to work. But rapid progress in cryogenics means you no longer have to lower their temperature almost to absolute zero (-273℃). Modern "high temperature" superconductors only need to be cooled to -200℃, which can be done with liquid nitrogen—a cheap, readily available substance.

Overseas, however, they are proving themselves daily. Perhaps the most well-known example to date is in Germany's city of Essen. In 2014, engineers installed a 10 kilovolt (kV) superconducting cable in the dense city center. Even though it was only one kilometer long, it avoided the higher cost of building a third substation in an area where there was very limited space for infrastructure. Essen's cable is unobtrusive in a meter-wide easement and only 70cm below ground.

Superconducting cables can be laid underground with a minimal footprint and cost-effectively. They need vastly less land.

A conventional high voltage overhead cable requires an easement of about 130 meters wide, with pylons up to 80 meters high to allow for safety. By contrast, an underground superconducting cable would take up an easement of six meters wide, and up to 2 meters deep.

This has another benefit: overcoming community skepticism. At present, many locals are concerned about the vulnerability of high voltage overhead cables in bushfire-prone and environmentally sensitive regions, as well as the visual impact of the large towers and lines. Communities and farmers in some regions are vocally against plans for new 85-meter high towers and power lines running through or near their land.

Climate extremes, unprecedented windstorms, excessive rainfall and lightning strikes can disrupt power supply networks, as the Victorian town of Moorabool discovered in 2021.

What about cost? This is hard to pin down, as it depends on the scale, nature and complexity of the task. But consider this—the Essen cable cost around $20m in 2014. Replacing the six 500kV towers destroyed by windstorms near Moorabool in January 2020 cost $26 million.

While superconducting cables will cost more up front, you save by avoiding large easements, requiring fewer substations (as the power is at a lower voltage), and streamlining approvals.


Where would superconductors have most effect?
Queensland. The sunshine state is planning four new high-voltage transmission projects, to be built by the mid-2030s. The goal is to link clean energy production in the north of the state with the population centers of the south, similar to sending Canadian hydropower to New York to meet demand.

Right now, there are major congestion issues between southern and central Queensland, and subsea links like Scotland-England renewable corridors highlight how to move power at scale. Strategically locating superconducting cables here would be the best location, serving to future-proof infrastructure, reduce emissions and avoid power loss.
