The blackout of 2003 knocked out power in the northeast, affecting cities in eight states and Ontario, Canada. This article appeared in the August 15, 2003 edition of the New York Times:

A surge of electricity to western New York and Canada touched off a series of power failures and enforced blackouts yesterday that left parts of at least eight states in the Northeast and the Midwest without electricity. The widespread failures provoked the evacuation of office buildings, stranded thousands of commuters and flooded some hospitals with patients suffering in the stifling heat.

In an instant that one utility official called ''a blink-of-the-eye second'' shortly after 4 p.m., the grid that distributes electricity to the eastern United States became overloaded. As circuit breakers tripped at generating stations from New York to Michigan and into Canada, millions of people were instantly caught up in the largest blackout in American history.

In New York City, power was shut off by officials struggling to head off a wider blackout. Cleveland and Detroit went dark, as did Toronto and sections of New Jersey, Pennsylvania, Connecticut and Massachusetts. In some areas, the power problems were scattered. The lights remained on in Albany and in Buffalo, but not in nearby suburbs.

Officials worked into the night to put the grid back in operation and restore electric service. Mayor Michael R. Bloomberg said that that the power was back on in parts of Brooklyn, the Bronx and Queens by 11 p.m. - but not Manhattan. ''We're certainly not out of the woods yet,'' the mayor said.

He said that New Yorkers should treat today ''like a snow day'' - listen to the radio and ''exercise your common sense.'' Transit officials said there would be no subway service for the rush hour this morning. Mr. Bloomberg said that he expected the subways to be running eventually today, but that traffic lights might be out of sequence.

''It wouldn't be the worst thing to do to take a day off,'' he said.

The blackout began just after the stock exchanges had closed for the day, a slow summer day of relatively light trading, as thousands of workers were about to head home. Office workers who were still at their desks watched their computer monitors blink off without warning on a hot and hazy afternoon. Soon hospitals and government buildings were switching on backup generators to keep essential equipment operating, and the police were evacuating people trapped in elevators.

Airports throughout the affected states suffered serious disruptions, including the three major airports in the New York metropolitan region, but did not close. Still, delays and cancellations rippled all the way to San Francisco. Federal Aviation Administration officials said the airports in the affected states had switched to emergency power. They said that airliners in the air had not been in danger, although many were rerouted to terminals beyond the blackout.

Thousands of subway passengers in New York City had to be evacuated from tunnels, and commuter trains also came to a halt. Gov. George E. Pataki said that 600 trains were stranded.

Officials said that the cause of the blackout was under investigation but that terrorism did not appear to have played a role. Tom Ridge, the homeland security secretary, met with his advisers in Washington. But Mayor Bloomberg said that there had been ''no evidence of any terrorism whatsoever.''

President Bush, who was in San Diego yesterday, said he planned to order a review of ''why the cascade was so significant.'' He also said the electrical grid might need to be modernized.

''It's a serious situation,'' he said.

''I have been working with federal officials to make sure the response to this situation was quick and thorough and I believe it has been,'' he told reporters.

The office of the Canadian prime minister, Jean Chrétien, initially said the power problems were caused by lightning in New York State but later retracted that. Canadian officials later expressed uncertainty about the exact cause but continued to insist the problem began on the United States side of the border. The Nuclear Regulatory Commission said that the seven nuclear plants in New York and New Jersey and two in the Midwest had shut down automatically when the failure occurred.

Telephone service was disrupted, especially calls to and from cellular phones. Most of the problems, telephone company officials said, had to do with heavy use. Officials said the trouble was compounded by power failures at some cellular transmitters. Cash-dispensing teller machines were also knocked out, so people who did not have cash on hand could not buy flashlights, batteries or other supplies.

The power failure exacted a variety of tolls in Michigan and Ohio, tying up the freeways in Detroit, forcing the cancellation of minor league baseball in Toledo, Ohio, and sending Jennifer M. Granholm, the governor of Michigan, into emergency meetings without the use of lights or computers.

In Times Square in New York, billboards instantly went dark and the city was left without traffic lights and the usual sounds of rush hour. Volunteers directed traffic with mixed success. Some stores in Manhattan closed as cashiers fumbled with registers that no longer toted up purchases. The Metropolitan Museum of Art emptied out, but not before some art lovers had pulled flashlights from backpacks and purses and trained them on paintings.

In a city still jittery from the Sept. 11 terror attack, some people worried as they tried to find their way home. ''All I could think was here we go again - it's just like Sept. 11,'' said Catherine Donnelly, who works at the New York Stock Exchange.

Mr. Pataki said he had ordered the National Guard to assist state and local authorities, but New York City officials said the Guard's aid was not necessary.

Police officials in the city said they first responded as if the power failure had been the work of terrorists, and with the concern that the city was suddenly vulnerable. Heavily armored officers were sent to likely targets and emergency command operations were begun in every borough.

The officials said that the city was mostly calm in the first hours of the blackout, and that every precinct in the city had moved to control traffic at critical intersections.

By midnight, though, the police reported several incidents of looting and bottle throwing in Lower Manhatan and Brooklyn.

So there was no air conditioning, no television, no computers. There was Times Square without its neon glow and Broadway marquees without their incandescence - all the shows were canceled. So was the Mets game against the San Francisco Giants at Shea Stadium. And there was a skyline that had never looked quite the way it did last night: the long, long taut strings of the bridges were dark, the red eyes that usually blink at the very top not red, not blinking.

As the lights came back on, officials estimated that 10 percent of the city's households again had power by 10 p.m. About that time, power was also restored in Newark and Buffalo.

''This is a very, very slow deliberate process, and you have to be very careful how you do it, or you will have the whole system fail again,'' said acting superintendent of New York State police, Wayne E. Bennett.

Mr. Bloomberg said the subways had been evacuated safely and that he believed the rescues of people from stuck elevators had gone smoothly. But one woman, after having walked down 18 flights of stairs at a Midtown office building, collapsed and died as passers-by, rescue workers and paramedics tried to save her.

As the afternoon dragged on with no lights and no word on how soon subways and trains might resume service, some hiked home. Others filled bars. A Kentucky Fried Chicken restaurant on East 14th Street near Avenue B gave away ice cream, one scoop to a customer. The Haagen-Dazs shop near Union Square had a ''power outage sale,'' selling cups and cones for $1 apiece.

Drivers, benefiting from suddenly very essential radios, flashed news bulletins to people in the street. ''It's a major grid, and it's out from Toronto to Ohio,'' Sharon Dennis told a throng that had gathered around her green Ford Taurus on West 34th Street shortly before 6 p.m. ''They say they don't know how long it will take to restore power.''

Mr. Pataki declared a state of emergency, and went to the Office of Emergency Management at the state police headquarters in Albany, where he said he would remain until power was restored.

Mr. Pataki reluctantly recalled one of the two major blackouts of the last 40 years in the Northeast - the 1965 power failure, which left an 80,000-square-mile stretch of the United States and Canada without electricity for as much as 27 hours. ''It wasn't supposed to happen again,'' he said, ''and it has happened again. And there have to be some tough questions asked as to why.''

The Nov. 9, 1965 blackout began with an overloaded relay at a hydroelectric plant in Ontario. That plunged Toronto into darkness, then Syracuse, then four of the five boroughs of New York City, which had been drawing 300,000 kilowatts from the Niagara Mohawk utility in upstate New York. The lights stayed on in parts of Brooklyn and on Staten Island, because of a generating station that was not knocked out.

On July 14, 1977, lightning hit two Con Edison transmission lines north of New York City, tripping relays that soon shut down power plants in the New York metropolitan area. Parts of the city were dark for more than 25 hours, and there was widespread looting.

Yesterday, the North American Electric Reliability Council, which was set up by the utility industry after the blackouts of 1965 to reduce the likelihood of cascading failures, said that power problems were felt throughout the entire eastern interconnection, which covers most of the country east of the Mississippi River. The South was unaffected by the blackout, the council said.

The council had issued its annual summer reliability assessment of the supply of electricity earlier in the year, concluding that the nation should have adequate resources to meet the demand for power this summer. But it warned of possible problems, particularly around New York City, if extreme weather produced unusually heavy demand.

Phillip G. Harris, who is in charge of the consortium that oversees power distribution from New Jersey to the District of Columbia, said the exact cause of the blackout would not be known for some time. ''We have to get into the forensics of it,'' he said. There was high demand for electricity yesterday, he said, ''but it was not any hotter than we had last year.''

He said that his system had recorded a ''massive outflow'' of power to northern New York or Canada shortly after 4 p.m. He said that the surge overloaded power lines that took themselves out of service.

For people with medical problems, the blackout added another layer of anxiety. Emergency rooms were flooded with patients with heat and heart ailments. At Harlem Hospital, a spokeswoman said that a number of pedestrians had been hit by cars because traffic lights were out.

At Jamaica Hospital in Queens, where even emergency power was lost for several hours, a spokeswoman said that officials there had been denied permission to divert patients to other hospitals.

In neighborhoods where memories of the 1977 blackout linger, yesterday did not bring the sounds of that long-ago evening. This time, there was little looting, officials said, and the grinding of iron store gates being forced up and the shattering of glass was absent.

In Bushwick, the Brooklyn neighborhood that was at the center of the vandalism in 1977, Mario Hernandez, a 44-year-old air-conditioner mechanic, remembered the looting well.

''I got five couches, five TV's, two stereo sets, gold chains, everything you could think of,'' he said yesterday, recalling that hot evening when he was 18. ''Even the decent people, the churchgoing people, were taking stuff back then.''

Police officers waited in the 83rd Precinct, on Knickerbocker Avenue. ''So far so good,'' an officer said. ''Nothing out of the ordinary. It's actually quieter than normal.''

There was at least one pocket of trouble: On the Lower East Side, an upscale sneaker store was broken into and one of the owners beaten and bloodied by a group of youths between 11 p.m. and midnight. ''These animals are wrecking my store,'' the owner said.

Canada to spend $2M on study to improve Atlantic region's electricity grid

Atlantic Clean Power Superhighway outlines a federally backed transmission grid upgrade for Atlantic Canada, adding 2,000 MW of renewable energy via interprovincial ties, improved hydro access from Quebec and Newfoundland and Labrador, with utility-regulator funding.

 

Key Points

A federal-provincial plan upgrading Atlantic Canada's grid to deliver 2,000 MW of renewables via interprovincial links.

✅ $2M technical review to rank priority transmission projects

✅ Target: add 2,000 MW renewable power to Atlantic grid

✅ Cost-sharing by utilities, regulators, and federal-provincial funding

 

The federal government will spend $2 million on an engineering study to improve the Atlantic region's electricity grid.

The study was announced Friday at a news conference held by 10 federal and provincial politicians at a meeting of the Atlantic Growth Strategy in Halifax, which includes ongoing regulatory reform efforts for cleaner power in Atlantic Canada.

The technical review will identify the most important transmission projects including inter-provincial ties needed to move electricity across the region.

Nova Scotia Premier Stephen McNeil said the results are expected in July.

Provinces will apply to the federal government for federal funding to build the infrastructure. Utilities in each province will be expected to pay some portion of the cost by applying to respective regulators, but what share falls to ratepayers is not known.

​Federal Intergovernmental Affairs Minister Dominic LeBlanc characterized the grid improvements as something that will cost hundreds of millions of dollars.

He said the study was the first step toward "a clean power superhighway across the region.

"We have a historic opportunity to quickly get to work on upgrading ultimately a whole series of transmission links of inter-provincial ties. That's something that the government of Canada would be anxious to work with in terms of collaborating with the provinces on getting that right."

Premier McNeil referred specifically to improving hydro access from Quebec and Newfoundland and Labrador.

For context, a massive cross-border hydropower line to New York is planned, illustrating the scale of projects under consideration.

 

Goal of 2,000 megawatts

McNeil said the goal was to bring an additional 2,000 megawatts of renewable electricity into the region.

"I can't stress to you enough how critical this will be for the future economic success and stability of Atlantic Canada, especially as Atlantic grids face intensifying storms," he said.

Federal Immigration Minister Ahmed Hussen also announced a pilot project to attract immigrant workers will be extended by two years to the end of 2021.

International graduate students will be given 24 months to apply under the program — a one-year increase.

Shell says electricity to meet 60 percent of China's energy use by 2060

China 2060 Carbon-Neutral Energy Transition projects tripled electricity, rapid electrification, wind and solar dominance, scalable hydrogen, CCUS, and higher carbon pricing to meet net-zero goals while decarbonizing heavy industry and transport.

 

Key Points

Shell's outlook for China to reach net zero by 2060 via electrification, renewables, hydrogen, CCUS, and carbon pricing.

✅ Power supply to 60% of energy; generation triples by 2060.

✅ Wind and solar reach 80% of electricity; coal declines sharply.

✅ Hydrogen scales to 17 EJ; CCUS and carbon pricing expand.

 

China may triple electricity generation to supply 60 percent of the country's total energy under Beijing's carbon-neutral goal by 2060, up from the current 23 per cent, according to Royal Dutch Shell.

Shell is one of the largest global investors in China's energy sector, with business covering gas production, petrochemicals and a retail fuel network. A leading supplier of liquefied natural gas, it has recently expanded into low-carbon business such as hydrogen power and electric vehicle charging.

In a rare assessment of the country's energy sector by an international oil major, Shell said China needed to take quick action this decade to stay on track to reach the carbon-neutrality goal.

China has mapped out plans to reach peak emissions by 2030, and aims to reduce coal power production over the coming years, but has not yet revealed any detailed carbon roadmap for 2060.

This includes investing in a reliable and renewable power system, including compressed air generation, and demonstrating technologies that transform heavy industry using hydrogen, biofuel and carbon capture and utilization.

"With early and systematic action, China can deliver better environmental and social outcomes for its citizens while being a force for good in the global fight against climate change," Mallika Ishwaran, chief economist of Shell International, told a webinar hosted by the company's China business.

Shell expects China's electricity generation to rise three-fold to more than 60 exajoules (EJ) in 2060 from 20 EJ in 2020, even amid power supply challenges reported recently.

Solar and wind power are expected to surpass coal as the largest sources of electricity by 2034 in China, reflecting projections that renewables will eclipse coal globally by mid-decade, versus the current 10 percent, rising to 80 percent by 2060, Shell said.

Hydrogen is expected to scale up to 17 EJ, or equivalent to 580 million tonnes of coal by 2060, up from almost negligible currently, adding over 85 percent of the hydrogen will be produced through electrolysis, supported by PEM hydrogen R&D across the sector, powered by renewable and nuclear electricity, Shell said.

Hydrogen will meet 16 percent of total energy use in 2060 with heavy industry and long-distance transport as top hydrogen users, the firm added.

The firm also expects China's carbon price to rise to 1,300 yuan (CDN$256.36) per tonne in 2060 from 300 yuan in 2030.

Nuclear, on a steady development track, and biomass will have niche but important roles for power generation in the years to come, Shell said.

Electricity generated from biomass, combined with carbon, capture, utilization and storage (CCUS), provide a source of negative emissions for the rest of the energy system from 2053, it added.

Extreme Heat Boosts U.S. Electricity Bills

Extreme Heat and Rising Electricity Bills amplify energy costs as climate change drives air conditioning demand, stressing the power grid and energy affordability, with low income households facing outsized burdens during prolonged heat waves.

 

Key Points

Heat waves from climate change raise AC demand, driving up electricity costs and straining energy affordability.

✅ More AC use spikes electricity demand during heat waves

✅ Low income households face higher energy burden

✅ Grid reliability risks rise with peak cooling loads

 

Extreme heat waves are not only straining public health systems but also having a significant impact on household finances, particularly through rising electricity bills. According to a recent AP-NORC poll, a growing number of Americans are feeling the financial pinch as soaring temperatures drive up the cost of cooling their homes. This development underscores the broader implications of climate change and its effects on everyday life.

The AP-NORC poll highlights that a majority of Americans are experiencing increased electricity costs as a direct result of extreme heat. As temperatures climb, so does the demand for air conditioning and other cooling systems. This increased energy consumption is contributing to higher utility bills, which can put additional strain on household budgets.

Extreme heat waves have become more frequent and intense due to climate change, which has led to a greater reliance on air conditioning to maintain comfortable indoor environments. Air conditioners and fans work harder during heat waves, and wasteful air conditioning can add around $200 to summer bills, consuming more electricity and consequently driving up energy bills. For many households, particularly those with lower incomes, these increased costs can be a significant burden.

The poll reveals that the impact of rising electricity bills is widespread, affecting a diverse range of Americans. Households across different income levels and geographic regions are feeling the heat, though the extent of the financial strain can vary. Lower-income households are particularly vulnerable, as they often have less flexibility in their budgets to absorb higher utility costs. For these families, the choice between cooling their homes and other essential expenses can be a difficult one.

In addition to financial strain, the poll highlights concerns about energy affordability and access. As electricity bills rise, some Americans may face challenges in paying their bills, leading to potential utility shut-offs or the need to make difficult choices between cooling and other necessities. This situation is exacerbated by the fact that many utility companies do not offer sufficient assistance or relief programs to help low-income households manage their energy costs.

The increasing frequency of extreme heat events and the resulting spike in electricity consumption also have broader implications for the energy infrastructure. Higher demand for electricity can strain power grids, as seen when California narrowly avoided blackouts during extreme heat, potentially leading to outages or reduced reliability. Utilities and energy providers may need to invest in infrastructure upgrades and maintenance to ensure that the grid can handle the increased load during heat waves.

Climate change is a key driver of the rising temperatures that contribute to higher electricity bills. As global temperatures continue to rise, extreme heat events are expected to become more common and severe, and experts warn the US electric grid was not designed to withstand these impacts. This trend underscores the need for comprehensive strategies to address both the causes and consequences of climate change. Efforts to reduce greenhouse gas emissions, improve energy efficiency, and invest in renewable energy sources are critical components of a broader climate action plan.

Energy efficiency measures can play a significant role in mitigating the impact of extreme heat on electricity bills. Upgrading to more efficient cooling systems, improving home insulation, and adopting smart thermostats can help reduce energy consumption and lower utility costs. Additionally, utility companies and government programs can offer incentives and rebates, including ways to tap new funding that help encourage energy-saving practices and support households in managing their energy use.

The poll also suggests that there is a growing awareness among Americans about the connection between climate change and rising energy costs. Many people are becoming more informed about the ways in which extreme weather events and rising temperatures impact their daily lives. This increased awareness can drive demand for policy changes and support for initiatives aimed at addressing climate change and improving energy efficiency, with many willing to contribute income to climate efforts, about the connection between climate change and rising energy costs.

In response to the rising costs and the impact of extreme heat, there are calls for policy interventions and support programs to help manage energy affordability. Proposals include expanding assistance programs for low-income households, investing in infrastructure improvements, and promoting energy efficiency initiatives alongside steps to make electricity systems more resilient to climate risks. By addressing these issues, policymakers can help alleviate the financial burden on households and support a more resilient and sustainable energy system.

Debates over policy impacts on electricity prices continue; in Alberta, federal policies are blamed by some for higher rates, illustrating how regulation can affect affordability.

In conclusion, the AP-NORC poll highlights the growing financial impact of extreme heat on American households, with rising electricity bills being a significant concern for many. The increased demand for cooling during heat waves is straining household budgets and raising broader questions about energy affordability and infrastructure resilience. Addressing these challenges requires a multifaceted approach, including efforts to combat climate change, improve energy efficiency, and provide support for those most affected by rising energy costs. As extreme heat events become more common, finding solutions to manage their impact will be crucial for both individual households and the broader energy system.

More than Two-thirds of Americans Indicate Willingness to Give or Donate Part of their Income in Support of the Fight Against Climate Change

U.S. Climate Change Donation Survey reveals Americans' willingness to fund sustainability via government incentives, electrification, and renewable energy. Public opinion favors wind, solar, and decarbonization, highlighting policy support post-pandemic amid economic recovery efforts.

 

Key Points

A 2020 U.S. poll on climate attitudes: donation willingness, renewable support, and views on government incentives.

✅ 70% would donate income; 31% would donate nothing.

✅ 59% prefer government incentives; 47% support taxes, conservation.

✅ 85% land wind, 83% offshore wind, 90% solar support.

 

A new study of American consumers' attitudes toward climate change finds that more than two-thirds of respondents (70%) indicate their willingness to give or donate a percentage of their personal income to support the fight against climate change and the path to net-zero electricity emissions by mid-century. 

Twenty-eight percent indicated they were willing to provide less than 1% of their income; 33% said they would be willing to contribute 1-5% of their income; 6% said they would give between 6-10% of their income; and 3% indicated they would contribute more than 10% of their income. Just under one-third (31%) of those surveyed indicated they were unwilling to give or donate any percentage of their income to support the fight against climate change.

The U.S. findings are part of a series of surveys commissioned by Nexans in the U.S., UK and France, in order to determine public opinion on climate change and related issues in the wake of the COVID-19 pandemic. The U.S. study was conducted online by Researchscape from August 20 – 24, 2020. It had 1,013 respondents, ages 18 or older, with the results weighted to be representative of the overall population (variables available upon request).

Nexans, is headquartered in Paris with a major offshore wind cable manufacturing facility in Charleston, S.C. and an industrial cable manufacturing facility in El Dorado, Ark. The company is fully committed to fighting climate change and is helping to make sustainable electrification possible. The survey was developed as part of its celebration of the first Climate Day in Paris which included a roundtable event with world-renowned experts, the release of an unprecedented global study by Roland Berger on the challenges raised by the electrification of the world, the question of whether the global energy transition is on track, and Nexans' own commitment to be carbon neutral by 2030.

Paying the Tab to Address Climate Change

Participants were given the opportunity to choose from seven multiple responses to the question "How should the fight against climate change be paid for?" The majority (59%) replied it should be paid for by "government incentives for both businesses and consumers." It was followed by "federal, state and/or local taxes" and "conservation programs" (tied at 47%); "business investments" (42%), such as carbon-free electricity initiatives, and "consumer-driven purchases" (33%). Just 9% selected none of the above and 2% selected other.

"Through the organization of this Climate Day, Nexans is asserting itself not only as an actor but also a thought leader of the energy transition for a sustainable electrification of the world. This electrification raises a number of challenges and paradoxes that must be overcome. And it will only happen with the direct involvement of the populations concerned. These surveys provide a better understanding of the level of information and disinformation, including climate change denial, in public opinion as well as their level of acceptability of these lifestyle changes," said Christopher Guérin, CEO, Nexans.

Among other findings, 44% are dissatisfied with the job that federal and state governments are doing to address climate change, while utilities like Duke Energy face investor pressure to release climate reports, 35% are somewhat satisfied and 21% are either very satisfied or completed satisfied with government's role.

Americans expressed overwhelmingly favorable views of wind and solar renewable energy proposals, as carbon emissions fall when electricity producers move away from coal. Specifically, 85% stated being in favor of wind turbines on land (15% against), 83% in favor of wind turbines off the coast (17% against) and 90% in support of solar panel farms (10% opposed).

Those surveyed were asked about their current and changing priorities towards climate change as influenced by the coronavirus pandemic and impacts like extreme heat on electricity bills. Thirty-nine percent indicated that climate change was no more and no less a priority due to the current health emergency; just under a third (31%) indicated that climate change is more of a priority while 30% said it was less of a priority.

In similar research conducted by Nexans in the United Kingdom, nearly two thirds (65.8%) of UK respondents said they would be willing to donate part of their salary to fight climate change. Furthermore, nearly a third (29%) of the UK's consumers believe that combating climate change has become more of a priority in light of the coronavirus pandemic. The UK research was conducted online by Savanta from August 21 – 24, 2020. A total of 2210 respondents, aged 16 and above, representative of the UK population took part.

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Key Points

ComEd's smart grid performance, cutting outages and improving power quality to enhance reliability and customer savings.

✅ Smart switches reroute power to avoid customer interruptions

✅ Fewer outages during extreme weather across northern Illinois

✅ Peak Time Savings rewards for reduced peak demand usage

 

While the summer of 2019 set records for heat and brought severe storms, ComEd customers stayed cool thanks to record-setting reliability during the season. These smart grid investments over the last seven years helped to set records in key reliability measurements, including frequency of outages metrics, and through smart switches that reroute power around potential problem areas, avoided more than 538,000 customer interruptions from June to August.

"In a summer where we were challenged by extreme weather, we saw our smart grid investments and our people continue to deliver the highest levels of reliability, backed by extensive disaster planning across utilities, for the families and businesses we serve," said Joe Dominguez, CEO of ComEd. "We're proud to deliver the most affordable, cleanest and, as we demonstrated this summer, most reliable energy to our customers. I want to thank our 6,000 employees who work around the clock in often challenging conditions to power our communities."

ComEd has avoided more than 13 million customer interruptions since 2012, due in part to smart grid and system improvements. The avoided outages have resulted in $2.4 billion in estimated savings to society. In addition to keeping energy flowing for residents, strong power reliability continues to help persuade industrial and commercial companies to expand in northern Illinois and Chicago. The GridWise Alliance recently recognized Illinois as the No. 2 state in the nation for its smart grid implementation.

"Our smart grid investments has vastly improved the infrastructure of our system," said Terry Donnelly, ComEd president and chief operating officer. "We review the system and our operations continually to make sure we're investing in areas that benefit the greatest number of customers, and to prepare for public-health emergencies as well. On a daily basis and during storms or to reduce wildfire risk when necessary, our customers are seeing fewer and fewer interruptions to their lives and businesses."

ComEd customers also set records for energy savings this summer. Through its Peak Time Savings program and other energy-efficiency programs offered by utilities, ComEd empowered nearly 300,000 families and individuals to lower their bills by a total of more than $4 million this summer for voluntarily reducing their energy use during times of peak demand. Since the Peak Time Savings program launched in 2015, participating customers have earned a total of more than $10 million in bill credits.
