A rock found mostly in Oman can be harnessed to soak up the main greenhouse gas carbon dioxide at a rate that could help slow global warming, scientists say.

When carbon dioxide comes in contact with the rock, peridotite, the gas is converted into solid minerals such as calcite.

Geologist Peter Kelemen and geochemist Juerg Matter said the naturally occurring process can be supercharged 1 million times to grow underground minerals that can permanently store 2 billion or more of the 30 billion tons of carbon dioxide emitted by human activity every year.

Their study will appear in the November 11 edition of the Proceedings of the Natural Academy of Sciences.

Peridotite is the most common rock found in the Earth's mantle, or the layer directly below the crust. It also appears on the surface, particularly in Oman, which is conveniently close to a region that produces substantial amounts of carbon dioxide in the production of fossil fuels.

"To be near all that oil and gas infrastructure is not a bad thing," Matter said in an interview.

They also calculated the costs of mining the rock and bringing it directly to greenhouse gas emitting power plants, but determined it was too expensive.

The scientists, who are both at Columbia University's Lamont-Doherty Earth Observatory in New York, say they have kick-started peridotite's carbon storage process by boring down and injecting it with heated water containing pressurized carbon dioxide. They have a preliminary patent filing for the technique.

They say 4 billion to 5 billion tons a year of the gas could be stored near Oman by using peridotite in parallel with another emerging technique developed by Columbia's Klaus Lackner that uses synthetic "trees" which suck carbon dioxide out of the air.

More research needs to be done before either technology could be used on a commercial scale.

Peridotite also occurs in the Pacific islands of Papua New Guinea and Caledonia, and along the coast of the Adriatic Sea and in smaller amounts in California.

Big greenhouse gas emitters like the United States, China and India, where abundant surface supplies of the rock are not found, would have to come up with other ways of storing or cutting emissions.

Rock storage would be safer and cheaper than other schemes, Matter said.

Many companies are hoping to cut their greenhouse gas emissions by siphoning off large amounts of carbon dioxide from coal-fired power plants and storing it underground.

That method could require thousands of miles of pipelines and nobody is sure whether the potentially dangerous gas would leak back out into the atmosphere in the future.

In North Carolina, unpaid electric and water bills are driving families and cities to the financial brink

North Carolina Utility Arrears Crisis strains households and municipal budgets as COVID-19 cuts jobs; unpaid utility bills mount, shutoffs loom, and emergency aid, unemployment benefits, and CARES Act relief lag behind rising arrears across cities.

 

Key Points

A COVID-19 driven spike in unpaid utility bills, threatening households and municipal budgets as federal aid lapses.

✅ 1 million families behind on power, water, sewage bills

✅ $218M arrears accrued April to June, double last year

✅ Municipal utilities face shutoffs, budget shortfalls

 

As many as 1 million families in North Carolina have fallen behind on their electric, water and sewage bills, a sign of energy insecurity threatening residents and their cities with severe financial hardship unless federal lawmakers act to approve more emergency aid.

The trouble stems from the widespread economic havoc wrought by the coronavirus, which has left millions of workers out of a job and struggling to cover their monthly costs as some states moved to suspend utility shut-offs to provide relief. Together, they’ve been late or missed a total of $218 million in utility payments between April 1 and the end of June, according to data released recently by the state, nearly double the amount in arrears at this time last year.

In some cases, cities that own or operate their own utilities have been forced to absorb these losses, as some utilities reconnected customers to prevent harm, creating a dire situation in which the government’s attempt to save people from the financial brink instead has pushed municipal coffers to their own breaking point.

In Elizabeth City, N.C., for example, about 2,500 residents haven’t paid their electric bills on time, according to Richard Olson, the city manager. The late payments at one point proved so problematic that Olson said he calculated Elizabeth City wouldn’t have enough money to pay for its expenses in July. In response, city leaders requested and obtained a waiver from a statewide order, similar to New York’s disconnection moratorium, issued in March, that protects people from being penalized for their past-due utility bills.

The predicament has presented unique budget challenges throughout North Carolina, while illustrating the consequences of a cash crunch plaguing the entire country, where proposals such as a Texas electricity market bailout surfaced following severe grid stress. State and federal leaders have extended a range of coronavirus relief programs since March to try to help people through the pandemic. But the money is limited and restricted — and it’s not clear whether more help from Congress is on the way — creating a crisis in which the nation’s economic woes are outpacing some of the aid programs adopted to combat them.

“We are entering a phase where the utilities [may] be able to shut off power, but what was propping up people’s economic lives, the unemployment benefits and Cares Act support, won’t be there,” said Paul Meyer, the executive director of the North Carolina League of Municipalities.

White House, GOP in disarray over coronavirus spending plan as deadline nears on expiring emergency aid

The future of that safety-net support — and other federal aid — hangs in the balance as lawmakers returned to work this week in their final sprint ahead of the August recess. The White House and congressional leaders are split over the contours of the next coronavirus relief package, including the need to extend more aid to cities and states as some utilities have waived fees to help customers, and reauthorize an extra $600 in weekly unemployment payments that were approved as part of the Cares Act in March.

Outside Washington, workers, businesses and government officials nationwide have pleaded with federal lawmakers to renew or expand those programs. Last week, Roy Cooper, the Democratic governor of North Carolina, urged Congress to act swiftly and adopt a wide array of new federal spending, including proposals for DOE nuclear cleanup funding, stressing in a letter that the “actions you take in the next few weeks are vital to our ability to emerge from this crisis. ”

Ontario Launches Peak Perks Program

Ontario Peak Perks Program boosts energy efficiency with smart thermostats, demand response, and incentives, reducing peak demand, electricity costs, and emissions while supporting grid reliability and Save on Energy initiatives across Ontario businesses and homes.

 

Key Points

A demand response initiative offering incentives via smart thermostats to cut peak electricity use and lower costs

✅ $75 sign-up, $20 yearly enrollment incentive

✅ Up to 10 summer temperature events; opt-out anytime

✅ Expanded retrofits, greenhouse support, grid savings

 

The Ontario government is launching the new Peak Perks program to help families save money by conserving energy, building on bill support during COVID-19 initiatives as part of the government’s $342 million expansion of Ontario’s energy-efficiency programs that will reduce demands on the provincial grid. The government is also launching three new and enhanced programs for businesses, municipalities, and other institutions, including targeted support for greenhouse growers in Southwest Ontario.

“Our government is giving families more ways to lower their energy bills with new energy-efficiency programs like Peak Perks and ultra-low overnight rates available to consumers, which will provide families a $75 financial incentive this year in exchange for lowering their energy use at peak times during the summer,” said Todd Smith, Minister of Energy. “The new programs launched today will also help meet the province’s emerging electricity system needs by providing annual electricity savings equivalent to powering approximately 130,000 homes every year and, alongside electricity cost allocation discussions, reduce costs for consumers by over $650 million by 2025.”

The new Peak Perks program provides a financial incentive for residential customers who are willing to conserve energy and reduce their air conditioning at peak times and have an eligible smart thermostat connected to a central air conditioning system or heat pump unit. Participants will receive $75 for enrolling this year, as well as $20 for each year they stay enrolled in the program starting in 2024.

Residential customers can participate in Peak Perks by enrolling and giving their thermostat manufacturer secure access to their thermostat. Participants will be notified when one of the maximum 10 annual temperature change events occurs directly by their thermostat manufacturer on their mobile app and on their thermostat. Peak Perks has been designed to ensure participants are always in control and customers can opt-out of any temperature change event without impacting their incentive.

The Peak Perks program will be available starting in June. Interested customers can visit SaveOnEnergy.ca/PeakPerks today to sign-up for the program waitlist and receive an email notice with information on how to enroll.

In addition to the financial incentive provided by Peak Perks, reducing electricity use during peak demand hours in the summer months helps customers to lower their monthly electricity bills, and measures such as a temporary off-peak rate freeze have complemented these efforts, as these periods tend to be associated with the highest costs for power. Lowering demand during peak periods also allows the province to reduce electricity sector emissions, by reducing the need for electricity generation facilities that only run at times of peak demand such as natural gas.

Ontario has also launched three new and enhanced programs, including an expanded custom Retrofit program for business, municipalities and other institutions, and industrial electricity rate relief initiatives, targeted support for greenhouse growers in Southwest Ontario, as well enhancements to the existing Local Initiatives Program. The expanded Retrofit program alone will feature over $200 million in dedicated funding to support the new custom energy-efficiency retrofit project stream, that will cover up to 50 percent of the cost of approved projects.

These new and expanded energy-efficiency programs are expected to have a strong impact in Southwest Ontario, with regional peak demand savings of 225 megawatts (MW). This, together with the Ontario-Quebec energy swap agreement, will provide additional capacity for the region and support growing economic development. The overall savings from this energy-efficiency programming will result in an estimated three million tonnes of greenhouse gas emission reductions over its lifetime - the equivalent to taking more than 600,000 vehicles off the road for one year.

“Thanks to energy efficiency efforts over the past 15 years, demand for electricity is today about 12 per cent lower than it otherwise would be,” said Lesley Gallinger, President and CEO, of the Independent Electricity System Operator, Ontario’s grid operator and provider of Save on Energy programs to home and business consumers. “Conservation is a valuable and cost-effective resource that supports system reliability and helps drive economic development as we strive towards compliance with clean electricity regulations for a decarbonized electricity grid.”

Ontario's electric debacle: Liberal leadership candidates on how they'd fix power

Ontario Electricity Policy debates rates, subsidies, renewables, nuclear baseload, and Quebec hydro imports, highlighting grid transmission limits, community consultation, conservation, and the province's energy mix after cancelled wind projects and rising costs to taxpayers.

 

Key Points

Ontario Electricity Policy guides rates, generation, grid planning, subsidies and imports for reliable, low-cost power.

✅ Focuses on rates, subsidies, and consumer affordability

✅ Balances nuclear baseload, renewables, and Quebec hydro imports

✅ Emphasizes grid transmission, consultation, and conservation

 

When Kathleen Wynne’s Liberals went down to defeat at the hands of Doug Ford and the Progressive Conservatives, Ontario electricity had a lot to do with it. That was in 2018. Now, two years later, Ford’s government has electricity issues of its own, including a new stance on wind power that continues to draw scrutiny.

Electricity is politically fraught in Ontario. It’s among the most expensive in Canada. And it has been mismanaged at least as far back as nuclear energy cost overruns starting in the 1980s.

From the start Wynne’s government was tainted by the gas plant scandal of her predecessor Dalton McGuinty and then she created her own with the botched roll-out of her green energy plan. And that helped Ford get elected promising to lower electricity prices. But, rates haven’t gone down under Ford while the cost to the government coffers for subsidizing them have soared - now costing $5.6 billion a year.

Meanwhile, Ford’s government has spent at least $230 million to tear up green energy contracts signed by the former Liberal government, including two wind-farm projects that were already mid-construction.

Lessons learned?
In the final part of a three-part series, the six candidates vying to become the next leader of the Ontario Liberals discuss the province's electricity system, including the lessons learned from the prior Liberal government's botched attempts to fix it that led to widespread local opposition to a string of wind power projects, and whether they'd agree to import more hydroelectricity from Quebec.

“We had the right idea but didn’t stick the landing,” said Steven Del Duca, a member of the former Wynne government who lost his Vaughan-area seat in 2018, referring to its green-energy plan. “We need to make sure that we work more collaboratively with local communities to gain the buy-in needed to be successful in this regard.”

“Consultation and listening is key,” agreed Mitzie Hunter, who was education minister under Kathleen Wynne and in 2018 retained her seat in the legislature representing Scarborough-Guildwood. “We must seek input from community members about investments locally,” she said. “Inviting experts in to advise on major policy is also important to make evidence-based decisions."

Michael Coteau, MPP for Don Valley East and the third leadership candidate who was a member of the former government, called for “a new relationship of respect and collaboration with municipalities.”

He said there is an “important balance to be achieved between pursuing province wide objectives for green-energy initiatives and recognizing and reflecting unique local conditions and circumstances.”

Kate Graham, who has worked in municipal public service and has not held a provincial public office, said that experts and local communities are best placed to shape decisions in the sector.

In the final part of a three-part series, Ontario's Liberal leadership contenders discuss electricity, lessons learned from the bungled rollout of previous Liberal green policy, and whether to lean more on Quebec's hydroelectricity.
“What's gotten Ontario in trouble in the past is when Queen's Park politicians are the ones micromanaging the electricity file,” she said.

“Community consultation is vitally important to the long-term success of infrastructure projects,” said Alvin Tedjo, a former policy adviser to Liberal ministers Brad Duguid and Glen Murray.

“Community voices must be heard and listened to when large-scale energy programs are going to be implemented,” agreed Brenda Hollingsworth, a personal injury lawyer making her first foray into politics.

Of the six candidates, only Coteau went beyond reflection to suggest a path forward, saying he would review the distribution of responsibilities between the province and municipalities, with the aim of empowering cities and towns.

Turn back to Quebec?
Ford’s government has also turned away from a deal signed in 2016 to import hydroelectricity from Quebec.

Graham and Hunter both said they would consider increasing such imports. Hunter noted that the deal, which would displace domestic natural gas production, will lower the cost of electricity paid by Ontario ratepayers by a net total of $38 million from 2017 to 2023, according to the province’s fiscal watchdog.

“I am open to working with our neighbouring province,” Hunter said. “This is especially important as we seek to bring electricity to remote northern, on-reserve Indigenous communities.”

Tedjo said he has no issues with importing clean energy as long as it’s at a fair price.

Hollingsworth and Coteau both said they would withhold judgment until they could see the province’s capacity status in 2022.

“In evaluating the case for increasing importation of water power from Quebec, we must realistically assess the limitations of the existing transmission system and the cost and time required to scale up transmission infrastructure, among other factors,” Coteau said.

Del Duca also took a wait-and-see approach. “This will depend on our energy needs and energy mix,” he said. “I want to see our energy needs go down; we need more efficiency and better conservation to make that happen.”

What's the right energy mix?
Nuclear energy currently accounts for about a third of Ontario’s energy-producing capacity, even as Canada explores zero-emissions electricity by 2035 pathways. But it actually supplies about 60 percent of Ontario’s electricity. That is because nuclear reactors are always on, producing so-called baseload power.

Hydroelectricity provides another 25 percent of supply, while oil and natural gas contribute 6 per cent and wind adds 7 percent. Both solar and biofuels account for less than one percent of Ontario’s energy supply. However, a much larger amount of solar is not counted in this tally, as it is used at or near the sites where it is generated, and never enters the transmission system.

Asked for their views on how large a role various sources of power should play in Ontario’s electricity mix in the future, the candidates largely backed the idea of renewable energy, but offered little specifics.

Graham repeated her statement that experts and communities should drive that conversation. Tedjo said all non-polluting technologies should play a role in Ontario’s energy mix, as provinces like Alberta demonstrate parallel growth in green energy and fossil fuels. Coteau said we need a mix of renewable-energy sources, without offering specifics.

“We also need to pursue carbon capture and sequestration, working in particular with our farming communities,” he added.

UK breaks coal free energy record again but renewables still need more support

UK Coal-Free Grid Streak highlights record hours without coal, as renewable energy, wind and solar boost electricity generation, cutting CO2 emissions, reducing fossil fuel reliance, and accelerating grid decarbonization amid volatile gas markets.

 

Key Points

It is the UKs longest coal-free power run, driven by renewables, signaling decarbonization and reduced gas reliance.

✅ Record-breaking hours of electricity with zero coal generation

✅ Enabled by wind, solar, and growing offshore wind capacity

✅ Highlights need to cut gas use and expand renewable investment

 

Today is the fourth the UK has entered with not a watt of electricity generated by coal.

It’s the longest such streak since the 1880s and comes only days after the last modern era coal-free power record of 55 hours was set.

That represents good news for those of us who have children and would rather like there to be a planet for them to live on when we’re gone.

Coal generated power is dirty power, and not just through the carbon that gets pumped into the atmosphere when it burns.

The fact that the UK is increasingly able to call upon cleaner alternatives for its requirements, to the extent that records are being regularly broken and coal's share has fallen to record lows, is a welcome development.

The trouble is one of those alternatives is gas, and while it is better than coal it still throws off CO2, among other pollutants. The UK’s use of it, for electricity generation and most of its heating, comes with the added disadvantage of leaving it in hock to volatile international markets and producers that aren’t always friendly.

It was only last month, with the country in the middle of a cold snap, that the Grid was issuing a deficit warning (its first in eight years).

As I wrote at the time, we need to burn less of the stuff as low-carbon progress stalled in 2019 shows, too.

As such, Greenpeace’s call for more investment in renewable energy technology and generation, including solar, onshore wind and offshore wind, which is making an increasing contribution as wind beat coal in 2016 demonstrated, was well made.

Those who complain about onshore wind farms, particularly when they are built in windy places that are pretty, seem willfully blind to the pollution caused by gas.

The need to be listened to less. So do those, like British Gas owner Centrica, that bellyache about green taxes.

It bears repeating that fossil fuels are subsidised still more. It’s just that the subsidies are typically hidden.

A report issued last year by a coalition of environmental organisations found the UK provided $972m (£695m) of annual financing for fossil fuels on average between 2013 and 2015, compared with $172m for renewable energy.

But while they come up with wildly varying amounts as a result of wildly varying approaches, the OECD, the IMF and the International Energy Agency have all quantified substantial subsidies for fossils fuels. Their annual estimates have ranged from $160bn to $5.3tn (yes you read that rate and the number was the IMF’s) globally.

So by all means celebrate coal free days, and a full week without coal power as milestones. But we need more of them more quickly and we need more renewable energy to pick up the slack. As such, the philosophy and approach of government needs to change.

Heatwave Sparks Unprecedented Electricity Demand Across Eastern U.S

Eastern U.S. Heatwave Electricity Demand surges to record peak load, straining the power grid, lifting wholesale prices, and prompting demand response, conservation measures, and load shedding to protect grid reliability during extreme temperatures.

 

Key Points

It is the record peak load from extreme heat, straining grids, lifting wholesale prices, and prompting demand response.

✅ Peak electricity use stresses regional power grid.

✅ Prices surge; conservation and demand response urged.

✅ Utilities monitor load, avoid outages via load shedding.

 

As temperatures soar to unprecedented highs across the Eastern United States, a blistering heatwave has triggered record-breaking electricity demand. This article delves into the causes behind the surge in energy consumption, its impact on the power grid, and measures taken to manage the strain during this extraordinary weather event.

Intensifying Heatwave Conditions

The Eastern U.S. is currently experiencing one of its hottest summers on record, with temperatures climbing well above seasonal norms. This prolonged heatwave has prompted millions of residents to rely heavily on air conditioning and cooling systems to escape the sweltering heat, with electricity struggles worsening in several communities, driving up electricity usage to peak levels.

Strain on Power Grid Infrastructure

The surge in electricity demand during the heatwave has placed significant strain on the region's power grid infrastructure, with supply-chain constraints complicating maintenance and equipment availability during peak periods.

Record-breaking Energy Consumption

The combination of high temperatures and increased cooling demands has led to record-breaking energy consumption levels across the Eastern U.S. States like New York, Pennsylvania, and Maryland have reported peak electricity demand exceeding previous summer highs, with blackout risks drawing heightened attention from operators, highlighting the extraordinary nature of this heatwave event.

Impact on Energy Costs and Supply

The spike in electricity demand during the heatwave has also affected energy costs and supply dynamics. Wholesale electricity prices have surged in response to heightened demand, contributing to sky-high energy bills for many households, reflecting the market's response to supply constraints and increased operational costs for power generators and distributors.

Management Strategies and Response

Utility companies and grid operators have implemented various strategies to manage electricity demand and maintain grid reliability during the heatwave. These include voluntary conservation requests, load-shedding measures, and real-time monitoring of grid conditions to prevent power outages while avoiding potential blackouts or disruptions.

Community Outreach and Public Awareness

Amidst the heatwave, community outreach efforts play a crucial role in raising public awareness about energy conservation and safety measures. Residents are encouraged to conserve energy during peak hours, adjust thermostat settings, and utilize energy-efficient appliances to alleviate strain on the power grid and reduce overall energy costs.

Climate Change and Resilience

The intensity and frequency of heatwaves are exacerbated by climate change, underscoring the importance of building resilience in energy infrastructure and adopting sustainable practices. Investing in renewable energy sources, improving energy efficiency and demand response programs that can reduce peak demand, and implementing climate adaptation strategies are essential steps towards mitigating the impacts of extreme weather events like heatwaves.

Looking Ahead

As the Eastern U.S. navigates through this heatwave, stakeholders are focused on implementing lessons learned from California's grid response to enhance preparedness and resilience for future climate-related challenges. Collaborative efforts between government agencies, utility providers, and communities will be crucial in developing comprehensive strategies to manage energy demand, promote sustainability, and safeguard public health and well-being during extreme weather events.

Conclusion

The current heatwave in the Eastern United States has underscored the critical importance of reliable and resilient energy infrastructure in meeting the challenges posed by extreme weather conditions. By prioritizing energy efficiency, adopting sustainable energy practices, and fostering community resilience, stakeholders can work together to mitigate the impacts of heatwaves and ensure a sustainable energy future for generations to come.

France and Germany arm wrestle over EU electricity reform

EU Electricity Market Reform CFDs seek stable prices via contracts for difference, balancing renewables and nuclear, shielding consumers, and boosting competitiveness as France and Germany clash over scope, grid expansion, and hydrogen production.

 

Key Points

EU framework using contracts for difference to stabilize power prices, support renewables and nuclear, and protect users.

✅ Guarantees strike prices for new low-carbon generation

✅ Balances consumer protection with industrial competitiveness

✅ Disputed scope: nuclear inclusion, grids, hydrogen eligibility

 

Despite record temperatures this October, Europe is slowly shifting towards winter - its second since the Ukraine war started and prompted Russia to cut gas supplies to the continent amid an energy crisis that has reshaped policy.

After prices surged last winter, when gas and electricity bills “nearly doubled in all EU capitals”, the EU decided to take emergency measures to limit prices.

In March, the European Commission proposed a reform to revamp the electricity market “to boost renewables, better protect consumers and enhance industrial competitiveness”.

However, France and Germany are struggling to find a compromise as rolling back prices is tougher than it appears and the clock is ticking as European energy ministers prepare to meet on 17 October in Luxembourg.


The controversy around CFDs
At the heart of the issue are contracts for difference (CFDs).

By providing a guaranteed price for electricity, CFDs aim to support investment in renewable energy projects.

France - having 56 nuclear reactors - is lobbying for nuclear energy to be included in the CFDs, but this has caught the withering eye of Germany.

Berlin suspects Paris of wanting an exception that would give its industry a competitive advantage and plead that it should only apply to new investments.


France wants ‘to regain control of the price’
The disagreement is at the heart of the bilateral talks in Hamburg, which started on Monday, between the French and German governments.

French President Emmanuel Macron promised “to regain control of the price of electricity, at the French and European level” and outlined a new pricing scheme in a speech at the end of September.

As gas electricity is much more expensive than nuclear electricity, France might be tempted to switch to a national system rather than a European one after a deal with EDF on prices to be more competitive economically.

However, France is "confident" that it will reach an agreement with Germany on electricity market reforms, Macron said on Friday.

Siding with France are other pro-nuclear countries such as Hungary, the Czech Republic and Poland, while Germany can count on the support of Austria, Luxembourg, Belgium and Italy amid opposition from nine EU countries to treating market reforms as a price fix.

But even if a last-minute agreement is reached, the two countries’ struggles over energy are creeping into all current European negotiations on the subject.

Germany wants a massive extension of electricity grids on the continent so that it can import energy; France is banking on energy sovereignty and national production.

France wants to be able to use nuclear energy to produce clean hydrogen, while Germany is reluctant, and so on.
