Italian solar goal tough but reachable

Waste-to-Graphene uses flash joule heating to convert carbon-rich trash into turbostratic graphene for composites, asphalt, concrete, and flexible electronics, delivering scalable, low-cost, high-quality material from food scraps, plastics, and tires with minimal processing.

Key Points

A flash heating method converting waste carbon into turbostratic graphene for scalable, low-cost industrial uses.

✅ Converts food scraps, plastics, and tires into graphene

✅ Produces turbostratic flakes that disperse well in composites

✅ Scalable, low-cost process via flash joule heating

Science doesn’t usually take after fairy tales. But Rumpelstiltskin, the magical imp who spun straw into gold, would be impressed with the latest chemical wizardry. Researchers at Rice University report today in Nature that they can zap virtually any source of solid carbon, from food scraps to old car tires, and turn it into graphene—sheets of carbon atoms prized for applications ranging from high-strength plastic to flexible electronics, and debates over 5G electricity use continue to evolve. Current techniques yield tiny quantities of picture-perfect graphene or up to tons of less prized graphene chunks; the new method already produces grams per day of near-pristine graphene in the lab, and researchers are now scaling it up to kilograms per day.

“This work is pioneering from a scientific and practical standpoint” as it promises to make graphene cheap enough to use to strengthen asphalt or paint, says Ray Baughman, a chemist at the University of Texas, Dallas. “I wish I had thought of it.” The researchers have already founded a new startup company, Universal Matter, to commercialize their waste-to-graphene process, while others are digitizing the electrical system to modernize infrastructure.

With atom-thin sheets of carbon atoms arranged like chicken wire, graphene is stronger than steel, conducts electricity and heat better than copper, and can serve as an impermeable barrier preventing metals from rusting, while advances such as superconducting cables aim to cut grid losses. But since its 2004 discovery, high-quality graphene—either single sheets or just a few stacked layers—has remained expensive to make and purify on an industrial scale. That’s not a problem for making diminutive devices such as high-speed transistors and efficient light-emitting diodes. But current techniques, which make graphene by depositing it from a vapor, are too costly for many high-volume applications. And higher throughput approaches, such as peeling graphene from chunks of the mineral graphite, produce flecks composed of up to 50 graphene layers that are not ideal for most applications.

Graphene comes in many forms. Single sheets, which are ideal for electronics and optics, can be grown using a method called chemical vapor deposition. But it produces only tiny amounts. For large volumes, companies commonly use a technique called liquid exfoliation. They start with chunks of graphite, which is just myriad stacked graphene layers. Then they use acids and solvents, as well as mechanical grinding, to shear off flakes. This approach typically produces tiny platelets each made up of 20 to 50 layers of graphene.

In 2014, James Tour, a chemist at Rice, and his colleagues found they could make a pure form of graphene—each piece just a few layers thick—by zapping a form of amorphous carbon called carbon black with a laser. Brief pulses heated the carbon to more than 3000 kelvins, snapping the bonds between carbon atoms; for comparison, researchers have also generated electricity from falling snow using triboelectric effects. As the cloud of carbon cooled, it coalesced into the most stable structure possible, graphene. But the approach still produced only tiny qualities and required a lot of energy.

Two years ago, Luong Xuan Duy, one of Tour’s graduate students, read that other researchers had created metal nanoparticles by zapping a material with electricity, creating the same brief blast of heat behind the success of the laser graphene approach. “I wondered if I could use that to heat a carbon source and produce graphene,” Duy says. So, he put a dash of carbon black in a clear glass vial and zapped it with 400 volts, similar in spirit to electrical weed zapping approaches in agriculture, for about 200 milliseconds. Initially he got junk. But after a bit of tweaking, he managed to create a bright yellowish white flash, indicating the temperature inside the vial was reaching about 3000 kelvins. Chemical tests revealed he had produced graphene.

It turned out to be a type of graphene that is ideal for bulk uses. As the carbon atoms condense to form graphene, they don’t have time to stack in a regular pattern, as they do in graphite. The result is a material known as turbostatic graphene, with graphene layers jumbled at all angles atop one another. “That’s a good thing,” Duy says. When added to water or other solvents, turbostatic graphene remains suspended instead of clumping up, allowing each fleck of the material to interact with whatever composite it’s added to.

“This will make it a very good material for applications,” says Monica Craciun, a materials physicist at the University of Exeter. In 2018, she and her colleagues reported that adding graphene to concrete more than doubled its compressive strength. Tour’s team saw much the same result. When they added just 0.05% by weight of their flash-produced graphene to concrete, the compressive strength rose 25%; graphene added to polydimethylsiloxane, a common plastic, boosted its strength by 250%.

As digital control spreads across energy networks, research to counter ransomware-driven blackouts is increasingly important for grid resilience.

Those results could reignite efforts to use graphene in a wide range of composites. Researchers in Italy reported recently that adding graphene to asphalt dramatically reduces its tendency to fracture and more than doubles its life span. Last year, Iterchimica, an Italian company, began to test a 250-meter stretch of road in Milan paved with graphene-spiked asphalt. Tests elsewhere have shown that adding graphene to paint dramatically improves corrosion resistance.

These applications would require high-quality graphene by the ton. Fortunately, the starting point for flash graphene could hardly be cheaper or more abundant: Virtually any organic matter, including coffee grounds, food scraps, old tires, and plastic bottles, can be vaporized to make the material. “We’re turning garbage into graphene,” Duy says.

Alliant Energy Net-Zero Carbon Plan outlines carbon-neutral electricity by 2050, coal retirements by 2040, major solar and wind additions, gas transition, battery storage, hydrogen, and carbon credits to reduce emissions and lower customer costs.

Key Points

Alliant Energy's strategy to reach carbon-neutral power by 2050 via coal phaseout, renewables, storage, and offsets.

✅ Targets net-zero electricity by 2050

✅ Retires all coal by 2040; expands solar and wind

✅ Uses storage, hydrogen, and offsets to bridge gaps

Alliant Energy has joined a small but growing group of utilities aiming for carbon-neutral electricity by 2050.

In a report released Wednesday, the Madison-based company announced a goal of “net-zero carbon dioxide emissions” from its electricity generation along with plans to eliminate all coal-powered generation by 2040, a decade earlier than the company’s previous target.

Alliant, which is pursuing plans that would make it the largest solar energy generator in Wisconsin, said it is on track to cut its 2005 carbon emissions in half by 2030.

Both goals are in line with targets an international group of scientists warn is necessary to avoid the most catastrophic impacts of climate change. But reducing greenhouse gasses was not the primary motivation, said executive vice president and general counsel Jim Gallegos.

“The primary driver is focused on our customers and communities and setting them up … to be competitive,” Gallegos said. “We do think renewables are going to do it better than fossil fuels.”

Alliant has told regulators it can save customers up to $6.5 billion over the next 35 years by adding more than 1,600 megawatts of renewable generation, closing one of its two remaining Wisconsin coal plants and taking other undisclosed actions.

In a statement, Alliant chairman and CEO John Larsen said the goal is part of broader corporate and social responsibility efforts “guided by our strategy and designed to deliver on our purpose — to serve customers and build stronger communities.”

Coal out; gas remains
The goal applies only to Alliant’s electricity generation — the company has no plans to stop distributing natural gas for heating — and is “net-zero,” meaning the company could use some form of carbon capture or purchase carbon credits to offset continuing emissions.

The plan relies heavily on renewable generation — seen in regions embracing clean power across North America — including the addition of up to 1,000 megawatts of new Wisconsin solar plants by the end of 2023 and 1,000 megawatts of Iowa wind generation added over the past four years — as well as natural gas generators to replace its aging coal fleet.

But Jeff Hanson, Alliant’s director of sustainability, said eliminating or offsetting all carbon emissions will require new tools, such as battery storage or possibly carbon-free fuels such as hydrogen, and awareness of the Three Mile Island debate over the role of nuclear power in the mix.

“Getting to the 2040 goals, that’s all based on the technologies of today,” Hanson said. “Can we get to net zero today? The challenge would be a pretty high bar to clear.”

Gallegos said the plan does not call for the construction of more large-scale natural gas generators like the recently completed $700 million West Riverside Energy Center in Beloit, though natural gas will remain a key piece of Alliant’s generation portfolio.

Alliant announced plans in May to close its 400-megawatt Edgewater plant in Sheboygan by the end of 2022, echoing how Alberta is retiring coal by 2023 as markets shift, but has not provided a date for the shutdown of the jointly owned 1,100-megawatt Columbia Energy Center near Portage, which received about $1 billion worth of pollution-control upgrades in the past decade.

Alliant’s Iowa subsidiary plans to convert its 52-year-old, 200-megawatt Burlington plant to natural gas by the end of next year and a pair of small coal-fired generators in Linn County by 2025. That leaves the 250-megawatt plant in Lansing, which is now 43 years old, and the 734-megawatt Ottumwa plant as the remaining coal-fired generators, even as others keep a U.S. coal plant running indefinitely elsewhere.

Earlier this year, the utility asked regulators to approve a roughly $900 million investment in six solar farms across the state with a total capacity of 675 megawatts, similar to plans in Ontario to seek new wind and solar to address supply needs. The company plans to apply next year for permission to add up to 325 additional megawatts.

Alliant said the carbon-neutral plan, which entails closing Edgewater along with other undisclosed actions, would save customers between $2 billion and $6.5 billion through 2055 compared to the status quo.

Tom Content, executive director of the Citizens Utility Board, said the consumer advocacy group wants to ensure that ratepayers aren’t forced to continue paying for coal plants that are no longer needed while also paying for new energy sources and would like to see a bigger role for energy efficiency and more transparency about the utilities’ pathways to decarbonization.

‘They could do better’
Environmental groups said the announcement is a step in the right direction, though they say utilities need to do even more to protect the environment and consumers.

Amid competition from cheaper natural gas and renewable energy and pressure from environmentally conscious investors, U.S. utilities have been closing coal plants at a record pace in recent years, as industry CEOs say a coal comeback is unlikely in the U.S., a trend that is expected to continue through the next decade.

“This is not industry leadership when we’re talking about emission reductions,” said Elizabeth Katt Reinders, regional campaign director for the Sierra Club, which has called on Alliant to retire the Columbia plant by 2026.

Closing Edgewater and Columbia would get Alliant nearly halfway to its emissions goals while saving customers more than $250 million over the next decade, according to a Sierra Club study released earlier this year.

“Retiring Edgewater was a really good decision. Investing in 1,000 megawatts of new solar is game-changing for Wisconsin,” Katt Reinders said. “In the same breath we can say this emissions reduction goal is unambitious. Our analysis has shown they can do far more far sooner.”

Scott Blankman, a former Alliant executive who now works as director of energy and air programs for Clean Wisconsin, said Alliant should not run the Columbia plant for another 20 years.

“If they’re saying they’re looking to get out of coal by 2040 in Wisconsin I’d be very disappointed,” Blankman said. “I do think they could do better.”

Alliant is the 15th U.S. investor-owned utility to set a net-zero target, according to the Natural Resources Defense Council, joining Madison Gas and Electric, which announced a similar goal last year. Minnesota-based Xcel Energy, which serves customers in western Wisconsin, was the first large investor-owned utility to set such a target, as state utilities report declining returns in coal operations.

Alberta Renewable Energy Procurement is surging as corporate PPAs drive wind and solar growth, with the Pembina Institute and the Business Renewables Centre linking buyers and developers in Alberta's energy-only market near Medicine Hat.

Key Points

A market-led approach where corporations use PPAs to secure wind and solar power from Alberta projects.

✅ Corporate PPAs de-risk projects and lock in clean power.

✅ Alberta's energy-only market enables efficient transactions.

✅ Skilled workforce supports wind, solar, legal, and financing.

Alberta has big potential when it comes to providing renewable energy, advocates say.

The Pembina Institute says the practice of corporations committing to buy renewable energy is just taking off in Canada, and Alberta has both the energy sector and the skilled workforce to provide it.

Earlier this week, a company owned by U.S. billionaire Warren Buffett announced a large new wind farm near Medicine Hat. It has a buyer for the power.

Sara Hastings-Simon, director of the Pembina's Business Renewables Centre, says this is part of a trend.

"We're talking about the practice of corporate institutions purchasing renewables to meet their own electricity demand. And this is a really well-established driver for renewable energy development in the U.S.," she said. "You may be hearing headlines like Google, Apple and others that are buying renewables and we're helping to bring this practice to Canada."

The Business Renewables Centre (BRC) is a not-for-profit working to accelerate corporate and institutional procurement of renewables in Canada. The group held its inaugural all members event in Calgary on Thursday.

Hastings-Simon says shareholders and investors are encouraging more use of solar and wind power in Canada.

"We have over 10 gigawatts of renewable energy projects in the pipeline that are ready for buyers. And so we see multinational companies coming to Canada to start to procure here, as well as Canadian companies understanding that this is an opportunity for them as well," Hastings-Simon said.

"It's really exciting to see business interests driving renewable energy development."

Hastings-Simon says renewable procurement could help dispel the narrative that it's all about oil and gas in Alberta by highlighting Alberta as a powerhouse for both green energy and fossil fuels in Canada.

She says the practice started with a handful of tech companies in the U.S. and has become more mainstream there, even as Canada remains a solar laggard to some observers, with more and more large companies wanting to reduce their energy footprint.

He says his U.S.-based organization has been working for years to speed up and expand the renewables market for companies that want to address their own sustainability.

"We try and make that a little bit easier by building out a community that can help to really reinforce each other, share lessons learned, best practices and then drive for transactions to have actual material impact worldwide," he said.

"We're really excited to be working with the Pembina group and the BRC Canada team," he said. "We feel our best value for this is just to support them with our experiences and lessons. They've been basically doing the same thing for many years helping to grow and grow and cultivate the market."

Porter says Alberta's market is more than ready.

"There are some precedent transactions already so people know it can work," he said. "The way Alberta is structured, being an energy-only market is useful. And I think that there is a strong ecosystem of both budget developers and service providers … that can really help these transactions get over the line."

As procurement ramps up, Hastings-Simon says Alberta already has the skilled workers needed to fill renewable energy jobs across the province.

"We have a lot of the knowledge that's needed, and that's everybody from the construction down through the legal and financing — all those pieces of building big projects," she said. "We are seeing increasing interest in people that want to become involved in that industry, and so there is increasing demand for training in things like solar power installation and wind technicians."

Hastings-Simon predicts an increase in demand for both the services and the workers.

"As this industry ramps up, we're going to need to have more workers that are active in those areas," she said. "So I think we can see a very nice increase — both the demand and the number of folks that are able to work in this field."

California Gas Plant Extensions keep Ormond Beach, AES Alamitos, and Huntington Beach on standby for grid reliability during heat waves, as regulators balance renewables, battery storage, and power, pending State Water Resources Control Board approval.

Key Points

State plan extending three coastal gas plants to 2026, adding capacity as California expands renewables and storage.

✅ Extends Ormond Beach, AES Alamitos, AES Huntington Beach

✅ Mitigates blackout risk during extreme heat and peak demand

✅ Pending State Water Resources Control Board approval

Temperatures in many California cities are cooling down this week, but a debate is simmering on how to generate enough electricity to power the state through extreme weather events while transitioning away from a reliance on fossil fuels as clean energy progress indicates statewide.

The California Energy Commission voted Wednesday to extend the life of three gas power plants along the state’s southern coast through 2026, even as natural-gas electricity records persist nationwide, postponing a shutoff deadline previously set for the end of this year. The vote would keep the decades-old facilities _ Ormond Beach Generating Station, AES Alamitos and AES Huntington Beach — open so they can run during emergencies.

The state is at a greater risk of blackouts during major events when many Californians simultaneously crank up their air conditioning, such as a blistering heat wave, illustrated by widespread utility shutoffs in recent years.

“We need to move faster in incorporating renewable energy. We need to move faster at incorporating battery storage. We need to build out chargers faster,” commissioner Patricia Monahan said amid an ongoing debate over the classification of nuclear power in California. “We’re working with all the energy institutions to do that, but we are not there yet.”

The plan, put together by the state’s Department of Water Resources, still needs final approval from the State Water Resources Control Board, which may vote on the issue next week. Democratic Gov. Gavin Newsom signed legislation last year creating an energy reserve the state could use as a last resort if there is likely to be an energy shortage, a challenge mirrored by Ontario electricity shortfall concerns elsewhere. The law allowed the Department of Water Resources to fund or secure power sources in those instances, after PG&E shutdown reasons drew attention to grid vulnerabilities.

The commission acknowledged it was a difficult decision. Environmentalists say the state needs to transition to more short- and long-term solutions that will help it move away from fossil fuels and to rely more on renewable energy sources like solar and wind, similar to Ontario's clean power push in recent years. They’re also concerned about the health impacts associated with pollution from gas plants.

Germany's Economic Downturn reflects an energy crisis, deindustrialization risks, export weakness, and manufacturing stress, amid Russia gas loss, IMF and EU recession forecasts, and debates over electricity price caps and green transition.

Key Points

An economic contraction from energy price shocks, export weakness, and bottlenecks in manufacturing and digitization.

✅ Energy shock after loss of cheap Russian gas

✅ Exports slump amid China slowdown and weak demand

✅ Policy gridlock on power price cap and permits

Germany went from envy of the world to the worst-performing major developed economy. What happened?

For most of this century, Germany racked up one economic success after another, dominating global markets for high-end products like luxury cars and industrial machinery, selling so much to the rest of the world that half the economy ran on exports.

Jobs were plentiful, the government’s financial coffers grew as other European countries drowned in debt, and books were written about what other countries could learn from Germany.

No longer. Now, Germany is the world’s worst-performing major developed economy, with both the International Monetary Fund and European Union expecting it to shrink this year.

It follows Russia’s invasion of Ukraine and the loss of Moscow’s cheap Russian gas that underpinned industry — an unprecedented shock to Germany’s energy-intensive industries, long the manufacturing powerhouse of Europe.

The sudden underperformance by Europe’s largest economy has set off a wave of criticism, handwringing and debate about the way forward.

Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, said Christian Kullmann, CEO of major German chemical company Evonik Industries AG.

From his 21st-floor office in the west German town of Essen, Kullmann points out the symbols of earlier success across the historic Ruhr Valley industrial region: smokestacks from metal plants, giant heaps of waste from now-shuttered coal mines, a massive BP oil refinery and Evonik’s sprawling chemical production facility.

These days, the former mining region, where coal dust once blackened hanging laundry, is a symbol of the energy transition, as the power sector’s balancing act continues with wind turbines and green space.

The loss of cheap Russian natural gas needed to power factories “painfully damaged the business model of the German economy,” Kullmann told The Associated Press. “We’re in a situation where we’re being strongly affected — damaged — by external factors.”

After Russia cut off most of its gas to the European Union, spurring an energy crisis in the 27-nation bloc that had sourced 40% of the fuel from Moscow, the German government asked Evonik to turn to coal by keeping its 1960s coal-fired power plant running a few months longer.

The company is shifting away from the plant — whose 40-story smokestack fuels production of plastics and other goods — to two gas-fired generators that can later run on hydrogen amid plans to become carbon neutral by 2030 and following the nuclear phase-out of recent years.

One hotly debated solution: a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition, amid an energy crisis that even saw a temporary nuclear extension to stabilize supply.

The proposal from Vice Chancellor Robert Habeck of the Greens Party has faced resistance from Chancellor Olaf Scholz, a Social Democrat, and pro-business coalition partner the Free Democrats. Environmentalists say it would only prolong reliance on fossil fuels, while others advocate a nuclear option to meet climate goals.

Kullmann is for it: “It was mistaken political decisions that primarily developed and influenced these high energy costs. And it can’t now be that German industry, German workers should be stuck with the bill.”

The price of gas is roughly double what it was in 2021, with a senior official arguing nuclear would do little to solve that gas issue, hurting companies that need it to keep glass or metal red-hot and molten 24 hours a day to make glass, paper and metal coatings used in buildings and cars.

A second blow came as key trade partner China experiences a slowdown after several decades of strong economic growth.

These outside shocks have exposed cracks in Germany’s foundation that were ignored during years of success, including lagging use of digital technology in government and business and a lengthy process to get badly needed renewable energy projects approved.

US Power Grid Blackouts highlight aging infrastructure, rising outages, and declining reliability per DOE and NERC data, with weather-driven failures, cyberattack risk, and underinvestment stressing utilities, transmission lines, and modernization efforts.

Key Points

US power grid blackouts are outages caused by aging grid assets, severe weather, and cyber threats reducing reliability.

✅ DOE and NERC data show rising outage frequency and duration.

✅ Weather now drives 68-73% of major failures since 2008.

✅ Modernization, hardening, and cybersecurity investments are critical.

The United States power grid has more blackouts than any other country in the developed world, according to new data and U.S. blackout warnings that spotlight the country’s aging and unreliable electric system.

The data by the Department of Energy (DOE) and the North American Electric Reliability Corporation (NERC) shows that Americans face more power grid failures lasting at least an hour than residents of other developed nations.

And it’s getting worse.

Going back three decades, the US grid loses power 285 percent more often than it did in 1984, when record keeping began, International Business Times reported. The power outages cost businesses in the United States as much as $150 billion per year, according to the Department of Energy.

Customers in Japan lose power for an average of 4 minutes per year, as compared to customers in the US upper Midwest (92 minutes) and upper Northwest (214), University of Minnesota Professor Massoud Amin told the Times. Amin is director of the Technological Leadership Institute at the school.

The grid is becoming less dependable each year, he said.

“Each one of these blackouts costs tens of hundreds of millions, up to billions, of dollars in economic losses per event,” Amin said. “… We used to have two to five major weather events per year [that knocked out power], from the ‘50s to the ‘80s. Between 2008 and 2012, major outages caused by weather, reflecting extreme weather trends, increased to 70 to 130 outages per year. Weather used to account for about 17 to 21 percent of all root causes. Now, in the last five years, it’s accounting for 68 to 73 percent of all major outages.”

As previously reported by Off The Grid News, the power grid received a “D+” grade on its power grid report card from the American Society of Civil Engineers (ASCE) in 2013. The power grid grade card rating means the energy infrastructure is in “poor to fair condition and mostly below standard, with many elements approaching the end of their service life.” It further means a “large portion of the system exhibits significant deterioration” with a “strong risk of failure.”

“America relies on an aging electrical grid and pipeline distribution systems, some of which originated in the 1880s,” the 2013 ASCE report read. “Investment in power transmission has increased since 2005, but ongoing permitting issues, weather events, and limited maintenance have contributed to an increasing number of failures and power interruptions.”

As The Times noted, the US power grid as it exists today was built shortly after World War II, with the design dating back to Thomas Edison. While Edison was a genius, he and his contemporaries could not have envisioned all the strains the modern world would place upon the grid and the multitude of tech gadgets many Americans treat as an extension of their body. While the drain on the grid has advanced substantially, the infrastructure itself has not.

There are approximately 5 million miles of electrical transmission lines throughout the United States, and thousands of power generating plants dot the landscape. The electrical grid is managed by a group of 3,300 different utilities and serve about 150 million customers, The Times said. The entire power grid system is currently valued at $876 billion.

Many believe the grid is vulnerable to an attack on substations and other threats.

Former Department of Homeland Security Secretary Janet Napolitano once said that a power grid cyber attack is a matter of “when” not “if,” as Russians hacked utilities incidents have shown.
