The Bangladeshi government will implement "electricity rationing" starting March 4 in order to cope with the ongoing power crisis, according to a government order issued recently.

"All markets and shopping malls in the country would remain closed after 7 p.m. everyday with effective Sunday, " said the order.

The government is hoping to save around 100 megawatt of electricity through implementation of the unique "electricity rationing" system.

Presently, the country experiences power shortage of 1,000 megawatt to 1,200 megawatt, and the shortfall could exceed 2,000 megawatt in the ensuing summer.

The total supply of electricity is varying between 2,600 megawatt to 2,800 megawatt against its demand of 3,600 megawatt to 3,800 megawatt.

Against this backdrop, the government has taken up steps to lessen the electricity crisis through rationalizing its overall supply system.

Meanwhile, it is adopting both short and medium terms policies to boost the country's power generation capacity.

3 ways 2021 changed electricity - What's Next

U.S. Power Sector Outlook 2022 previews clean energy targets, grid reliability and resilience upgrades, transmission expansion, renewable integration, EV charging networks, and decarbonization policies shaping utilities, markets, and climate strategies amid extreme weather risks.

 

Key Points

An outlook on clean energy goals, grid resilience, transmission, and EV infrastructure shaping U.S. decarbonization.

✅ States set 100% clean power targets; equity plans deepen.

✅ Grid reforms, transmission builds, and RTO debates intensify.

✅ EV plants, batteries, and charging corridors accelerate.

 

As sweeping climate legislation stalled in Congress this year, states and utilities were busy aiming to reshape the future of electricity.

States expanded clean energy goals and developed blueprints on how to reach them. Electric vehicles got a boost from new battery charging and factory plans.

The U.S. power sector also is sorting through billions of dollars of damage that will be paid for by customers over time. States coped with everything from blackouts during a winter storm to heat waves, hurricanes, wildfires and tornadoes. The barrage has added urgency to a push for increased grid reliability and resilience, especially as the power generation mix evolves, EV grid challenges grow as electricity is used to power cars and the climate changes.

“The magnitude of our inability to serve with these sort of discontinuous jumps in heat or cold or threats like wildfires and flooding has made it really clear that we can’t take the grid for granted anymore — and that we need to do something,” said Alison Silverstein, a Texas-based energy consultant.

Many of the announcements in 2021 could see further developments next year as legislatures, utilities and regulators flesh out details on everything from renewable projects to ways to make the grid more resilient.

On the policy front, the patchwork of state renewable energy and carbon reduction goals stands out considering Congress’ failure so far to advance a key piece of President Biden’s agenda — the "Build Back Better Act," which proposed about $550 billion for climate action. Criticism from fellow Democrats has rained on Sen. Joe Manchin (D-W.Va.) since he announced his opposition this month to that legislation (E&E Daily, Dec. 21).

The Biden administration has taken some steps to advance its priorities as it looks to decarbonize the U.S. power sector by 2035. That includes promoting electric vehicles, which are part of a goal to make the United States have net-zero emissions economywide no later than 2050. The administration has called for a national network of 500,000 EV charging stations as the American EV boom raises power-supply questions, and mandated the government begin buying only EVs by 2035.

Still, the fate of federal legislation and spending is uncertain. States and utility plans are considered a critical factor in whether Biden’s targets come to fruition. Silverstein also stressed the importance of regional cooperation as policymakers examine the grid and challenges ahead.

“Our comfort as individuals and as households and as an economy depends on the grid staying up,” Silverstein said, “and that’s no longer a given.”

Here are three areas of the electricity sector that saw changes in 2021, and could see significant developments next year:

 

1. Clean energy
The list of states with new or revamped clean energy goals expanded again in 2021, with Oregon and Illinois joining the ranks requiring 100 percent zero-carbon electricity in 2040 and 2050, respectively.

Washington state passed a cap-and-trade bill. Massachusetts and Rhode Island adopted 2050 net-zero goals.

North Carolina adopted a law requiring a 70 percent cut in carbon emissions by 2030 from 2005 levels and establishing a midcentury net-zero goal.

Nebraska didn’t adopt a statewide policy, but its three public power districts voted separately to approve clean energy goals, actions that will collectively have the same effect. Even the governor of fossil-fuel-heavy North Dakota, during an oil conference speech, declared a goal of making the state carbon-neutral by the end of the decade.

These and other states join hundreds of local governments, big energy users and utilities, which were also busy establishing and reworking renewable energy and climate goals this year in response to public and investor pressure.

However, many of the details on how states will reach those targets are still to be determined, including factors such as how much natural gas will remain online and how many renewable projects will connect to the grid.

Decisions on clean energy that could be made in 2022 include a key one in Arizona, which has seen support rise and fall over the years for a proposal to lead to 100 percent clean power for regulated electric utilities. The Arizona Corporation Commission could discuss the matter in January, though final approval of the plan is not a sure thing. Eyes also are on California, where a much bigger grid for EVs will be needed, as it ponders a recent proposal on rooftop solar that has supporters of renewables worried about added costs that could hamper the industry.

In the wake of the major energy bill North Carolina passed in 2021, observers are waiting for Duke Energy Corp.’s filing of its carbon-reduction plan with state utility regulators. That plan will help determine the future electricity mix in the state.

Warren Leon, executive director of the Clean Energy States Alliance (CESA), said that without federal action, state goals are “going to be more difficult to achieve.”

State and federal policies are complementary, not substitutes, he said. And Washington can provide a tailwind and help states achieve their goals more quickly and easily.

“Progress is going to be most rapid if both the states and the federal government are moving in the same direction, but either of them operating independently of the others can still make a difference,” he said.

While emissions reductions and renewable energy goals were centerpieces of the state energy and climate policies adopted this year, there were some other common threads that could continue in 2022.

One that’s gone largely unnoticed is that an increasing number of states went beyond just setting targets for clean energy and have developed plans, or road maps, for how to meet their goals, Leon said.

Like the New Year resolutions that millions of Americans are planning — pledges to eat healthier or exercise more — it’s far easier to set ambitious goals than to achieve them.

According to CESA, California, Colorado, Nevada, Maine, Rhode Island, Massachusetts and Washington state all established plans for how to achieve their clean energy goals. Prior to late 2020, only two states — New York and New Jersey — had done so.

Another trend in state energy and climate policies: Equity and energy justice provisions factored heavily in new laws in places such as Maine, Illinois and Oregon.

Equity isn’t a new concern for states, Leon said. But state plans have become more detailed in terms of their response to ways the energy transition may affect vulnerable populations.

“They’re putting much more concrete actions in place,” he said. “And they are really figuring out how they go about electricity system planning to make sure there are new voices at the table, that the processes are different, and there are things that are going to be measured to determine whether they’re actually making progress toward equity.”

 

2. Grid
Climate change and natural disasters have been a growing worry for grid planners, and 2021 was a year the issue affected many Americans directly.

Texas’ main power grid suffered massive outages during a deadly February winter storm, and it wasn’t far from an uncontrolled blackout that could have required weeks or months of recovery.

Consumers elsewhere in the country watched as millions of Texans lost grid power and heat amid a bitter cold snap. Other parts of the central United States saw more limited power outages in February.

“I think people care about the grid a lot more this year than they did last year,” Silverstein said, adding, “All of a sudden people are realizing that electricity’s not as easy as they’ve assumed it was and … that we need to invest more.”

Many of the challenges are not specific to one state, she added.

“It seems to me that the state regulators need to put a lot — and utilities need to put a lot — more commitment into working together to solve broad regional problems in cooperative regional ways,” Silverstein said.

In 2022, multiple decisions could affect the grid, including state oversight of spending on upgrades and market proposals that could sway the amount of clean energy brought online.

A focal point will be Texas, where state regulators are examining further changes to the Electric Reliability Council of Texas’ market design. That could have major implications for how renewables develop in the state. Leaders in other parts of the country will likely keep tabs on adjustments in Texas as they ponder their own changes.

Texas has already embarked on reforms to help improve the power sector and its coordination with the natural gas system, which is critical to keeping plants running. But its primary power grid, operated by ERCOT, remains largely isolated and hasn’t been able to rule out power shortages this winter if there are extreme conditions (Energywire, Nov. 22).

Transmission also remains a key issue outside of the Lone Star State, both for resilience and to connect new wind and solar farms. In many areas of the country, the job of planning these new regional lines and figuring out how to allocate billions of dollars in costs falls to regional grid operators (Energywire, Dec. 13).

In the central U.S., the issue led to tension between states in the Midwest and the Gulf South (Energywire, Oct. 15).

In the Northeast, a Maine environmental commissioner last month suspended a permit for a major transmission project that could send hydropower to the region from Canada (Greenwire, Nov. 24). The project’s developers are now battling the state in court to force construction of the line — a process that could be resolved in 2022 — after Mainers signaled opposition in a November vote.

Advocates of a regional transmission organization for Western states, meanwhile, hope to keep building momentum even as critics question the cost savings promoted by supporters of organized markets. Among those in existing markets, states such as Louisiana are expected to monitor the costs and benefits of being associated with the Midcontinent Independent System Operator.

In other states, more details are expected to emerge in 2022 about plans announced this year.

In California, where policymakers are also exploring EVs for grid stability alongside wildfire prevention, Pacific Gas & Electric Co. announced a plan over the summer to spend billions of dollars to underground some 10,000 miles of power lines to help prevent wildfires, for example (Greenwire, July 22).

Several Southeastern utilities, including Dominion Energy Inc., Duke Energy, Southern Co. and the Tennessee Valley Authority, won FERC approval to create a new grid plan — the Southeast Energy Exchange Market, or SEEM — that they say will boost renewable energy.

SEEM is an electricity trading platform that will facilitate trading close to the times when the power is used. The new market is slated to include two time zones, which would allow excess renewables such as solar and wind to be funneled to other parts of the country to be used during peak demand times.

SEEM is significant because the Southeast does not have an organized market structure like other parts of the country, although some utilities such as Dominion and Duke do have some operations in the region managed by PJM Interconnection LLC, the largest U.S. regional grid operator.

SEEM is not a regional transmission organization (RTO) or energy imbalance market. Critics argue that because it doesn’t include a traditional independent monitor, SEEM lacks safeguards against actions that could manipulate energy prices.

Others have said the electric companies that formed SEEM did so to stave off pressure to develop an RTO. Some of the regulated electric companies involved in the new market have denied that claim.

 

3. Electric vehicles
With electric vehicles, the Midwest and Southeast gained momentum in 2021 as hubs for electrifying the transportation sector, as EVs hit an inflection point in mainstream adoption, and the Biden administration simultaneously worked to boost infrastructure to help get more EVs on the road.

From battery makers to EV startups to major auto manufacturers, companies along the entire EV supply chain spectrum moved to or expanded in those two regions, solidifying their footprint in the fast-growing sector.

A wave of industry announcements capped off in December with California-based Rivian Automotive Inc. declaring it would build a $5 billion electric truck, SUV and van factory in Georgia. Toyota Motor Corp. picked North Carolina for its first U.S.-based battery plant. General Motors Co. and a partner plan to build a $2.5 billion battery plant in GM’s home state of Michigan. And Proterra Inc. has unveiled plans to build a new battery factory in South Carolina.

Advocates hope the EV shift by automakers in the Midwest and Southeast will widen the options for customers. Automakers and startups also have been targeting states with zero-emission vehicle targets to launch new and more models because there’s an inherent demand for them.

“The states that have adopted those standards are getting more vehicles,” said Anne Blair, senior EV policy manager for the Electrification Coalition.

EV advocates say they hope those policies could help bring products like Ford’s electrified signature truck line on the road and into rural areas. Ford also is partnering with Korean partner SK Innovation Co. Ltd. to build two massive battery plants in Kentucky.

Regardless of the fanfare about new vehicles, more jobs and must-needed economic growth, barriers to EV adoption remain. Many states have tacked on annual fees, which some elected officials argue are needed to replace revenues secured from a gasoline tax.

Other states do not allow automakers to sell directly to consumers, preventing companies like Lordstown Motors Corp. and Rivian to effectively do business there.

“It’s about consumer choice and consumers having the capacity to buy the vehicles that they want and that are coming out, in new and innovative ways,” Blair told E&E News. Blair said direct sales also will help boost EV sales at traditional dealerships.

In 2022, advocates will be closely watching progress with the National Electric Highway Coalition, amid tensions over charging control among utilities and networks, which was formed by more than 50 U.S. power companies to build a coast-to-coast fast-charging network for EVs along major U.S. travel corridors by the end of 2023 (Energywire, Dec. 7).

A number of states also will be holding legislative sessions, and they could include new efforts to promote EVs — or change benefits that currently go to owners of alternative vehicles.

EV advocates will be pushing for lawmakers to remove barriers that they argue are preventing customers from buying alternative vehicles.

Conversations already have begun in Georgia to let startup EV makers sell their cars and trucks directly to consumers. In Florida, lawmakers will try again to start a framework that will create a network of charging stations as charging networks jostle for position under federal electrification efforts, as well as add annual fees to alternative vehicles to ease concerns over lost gasoline tax revenue.

New fuel cell could help fix the renewable energy storage problem

Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

 

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

 

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

Ontario hydro rates set to increase Nov. 1, Ontario Energy Board says

Ontario Electricity Rebate clarifies hydro rates as OEB aligns bills with inflation, shows true cost per kilowatt hour, and replaces Fair Hydro Plan; transparent on-bill credit offsets increases tied to nuclear refurbishment and supply costs.

 

Key Points

A line-item credit on Ontario hydro bills that offsets higher electricity costs and reflects OEB-set rates.

✅ Starts Nov. 1 with rates in line with inflation

✅ Shows true per-kWh cost plus separate rebate line

✅ Driven by nuclear refurbishment and supply costs

 

The Ontario Energy Board says electricity rate changes for households and small businesses will be going up starting next week.

The agency says rates are scheduled to increased by about $1.99 or nearly 2% for a typical residential customer who uses 700 kilowatt hours per month.

The provincial government said in March it would continue to subsidize hydro rates, through legislation to lower rates, and hold any increases to the rate of inflation.

The OEB says the new rates, which the board says are “in line” with inflation, will take effect Nov. 1 as changes for electricity consumers roll out and could be noticed on bills within a few weeks of that date.

Prices are increasing partly due to government legislation aimed at reflecting the actual cost of supply on bills, and partly due to the refurbishment of nuclear facilities, contributing to higher hydro bills for some consumers.

So, effective November 1, Ontario electricity bills will show the true cost of power, after a period of a fixed COVID-19 hydro rate, and will include the new Ontario Electricity Rebate.

Previously the electricity rebate was concealed within the price-per-kilowatt-hour line item on electricity statements, prompting Hydro One bill redesign discussions to improve clarity. This meant customers could not see how much the government rebate was reducing their monthly costs, and bills did not display the true cost of electricity used.

"People deserve facts and accountability, especially when it comes to hydro costs," said Energy Minister Rickford.

The new Ontario Electricity Rebate will appear as a transparent on-bill line item and will replace the former government's Fair Hydro Plan says a government news release. This change comes in response to the Auditor General's special report on the former government's Fair Hydro Plan which revealed that "the government created a needlessly complex accounting/financing structure for the electricity rate reduction in order to avoid showing a deficit or an increase in net debt."

"The Electricity Distributors Association commends the government's commitment to making Ontario's electricity bills more transparent," said Teresa Sarkesian, President of the Electricity Distributors Association. "As the part of our electricity system that is closest to customers, local hydro utilities appreciated the opportunity to work with the government on implementing this important initiative. We worked to ensure that customers who receive their electricity bill will have a clear understanding of the true cost of power and the amount of their on-bill rebate. Local hydro utilities are focused on making electricity more affordable, reducing red tape, and providing customers with a modern and reliable electricity system that works for them."

The average customer will see the electricity line on their bill rise, showing the real cost per kilowatt hour. The new Ontario Electricity Rebate will compensate for that rise, and will be displayed as a separate line item on hydro bills. The average residential bill will rise in line with the rate of inflation.

Does Providing Electricity To The Poor Reduce Poverty? Maybe Not

Rural Electrification Poverty Impact examines energy access, grid connections, and reliability, testing economic development claims via randomized trials; findings show minimal gains without appliances, reliable supply, and complementary services like education and job creation initiatives.

 

Key Points

Study of household grid connections showing modest poverty impact without reliable power and appliances.

✅ Randomized grid connections showed no short-term income gains.

✅ Low reliability and few appliances limited electricity use.

✅ Complementary investments in jobs, education, health may be needed.

 

The head of Swedfund, the development finance group, recently summarized a widely-held belief: “Access to reliable electricity drives development and is essential for job creation, women’s empowerment and combating poverty.” This view has been the driving force behind a number of efforts to provide electricity to the 1.1 billion people around the world living in energy poverty, such as India's village electrification initiatives in recent years.

But does electricity really help lift households out of poverty? My co-authors and I set out to answer this question. We designed an experiment in which we first identified a sample of “under grid” households in Western Kenya—structures that were located close to but not connected to a grid. These households were then randomly divided into treatment and control groups. In the treatment group, we worked closely with the rural electrification agency to connect the households to the grid for free or at various discounts. In the control group, we made no changes. After eighteen months, we surveyed people from both groups and collected data on an assortment of outcomes, including whether they were employed outside of subsistence agriculture (the most common type of work in the region) and how many assets they owned. We even gave children basic tests, as a frequent assertion is that electricity helps children perform better in school since they are able to study at night.

When we analyzed the data, we found no differences between the treatment and control groups. The rural electrification agency had spent more than $1,000 to connect each household. Yet eighteen months later, the households we connected seemed to be no better off. Even the children’s test scores were more or less the same. The results of our experiment were discouraging, and at odds with the popular view that supplying households with access to electricity will drive economic development. Lifting people out of poverty may require a more comprehensive approach to ensure that electricity is not only affordable (with some evidence that EV growth can benefit all customers in mature markets), but is also reliable, useable, and available to the whole community, paired with other important investments.

For instance, in many low-income countries, the grid has frequent blackouts and maintenance problems, making electricity unreliable, as seen in Nigeria's electricity crisis in recent years. Even if the grid were reliable, poor households may not be able to afford the appliances that would allow for more than just lighting and cell phone charging. In our data, households barely bought any appliances and they used just 3 kilowatt-hours per month. Compare that to the U.S. average of 900 kilowatt-hours per month, a figure that could rise as EV adoption increases electricity demand over time.

There are also other factors to consider. After all, correlation does not equal causation. There is no doubt that the 1.1 billion people without power are the world’s poorest citizens. But this is not the only challenge they face. The poor may also lack running water, basic sanitation, consistent food supplies, quality education, sufficient health care, political influence, and a host of other factors that may be harder to measure but are no less important to well-being. Prioritizing investments in some of these other factors may lead to higher immediate returns. Previous work by one of my co-authors, for example, shows substantial economic gains from government spending on treatment for intestinal worms in children.

It’s possible that our results don’t generalize. They certainly don’t apply to enhancing electricity services for non-residential customers, like factories, hospitals, and schools, and electric utilities adapting to new load patterns. Perhaps the households we studied in Western Kenya are particularly poor (although measures of well-being suggest they are comparable to rural households across Sub-Saharan Africa) or politically disenfranchised. Perhaps if we had waited longer, or if we had electrified an entire region, the household impacts we measured would have been much greater. But others who have studied this question have found similar results. One study, also conducted in Western Kenya, found that subsidizing solar lamps helped families save on kerosene, but did not lead children to study more. Another study found that installing solar-powered microgrids in Indian villages resulted in no socioeconomic benefits.

Zapping elderly brains with electricity improves short-term memory — for almost an hour

Transcranial electrical stimulation synchronizes brain waves to bolster working memory, aligning neural oscillations across the prefrontal and temporal cortex. This noninvasive brain stimulation may counter cognitive aging by restoring network coupling and improving short-term recall.

 

Key Points

Transcranial electrical stimulation applies scalp currents to synchronize brain waves, briefly enhancing working memory.

✅ Synchronizes prefrontal-temporal networks to restore coupling

✅ Noninvasive tES/tACS protocols show rapid, reversible gains

✅ Effects lasted under an hour; durability remains to be tested

 

To read this sentence, you hold the words in your mind for a few seconds until you reach the period. As you do, neurons in your brain fire in coordinated bursts, generating electrical waves that let you hold information for as long as it is needed, much as novel devices can generate electricity from falling snow under specific conditions. But as we age, these brain waves start to get out of sync, causing short-term memory to falter. A new study finds that jolting specific brain areas with a periodic burst of electricity might reverse the deficit—temporarily, at least.

The work makes “a strong case” for the idea that out-of-sync brain waves in specific regions can drive cognitive aging, says Vincent Clark, a neuroscientist at the University of New Mexico in Albuquerque, who was not involved in the research. He adds that the brain stimulation approach in the study may result in a new electrical therapy for age-related deficits in working memory.

Working memory is “the sketchpad of the mind,” allowing us to hold information in our minds over a period of seconds. This short-term memory is critical to accomplishing everyday tasks such as planning and counting, says Robert Reinhart, a neuroscientist at Boston University who led the study. Scientists think that when we use this type of memory, millions of neurons in different brain areas communicate through coupled bursts of activity, a form of electrical conduction that coordinates timing across networks. “Cells that fire together, wire together,” Reinhart says.

But despite its critical role, working memory is a fragile cognitive resource that declines with age, Reinhart says. Previous studies had suggested that reduced working-memory performance in the elderly is linked to uncoupled activity in different brain areas. So Reinhart and his team set out to test whether recoupling brain waves in older adults could boost the brain’s ability to temporarily store information, a systems-level coordination challenge akin to efforts to use AI for energy savings on modern power grids.

To do so, the researchers used jolts of weak electrical current to synchronize waves in the prefrontal and temporal cortex—two brain areas critical for cognition, a targeted approach not unlike how grids use batteries to stabilize power during strain—and applied the current to the scalps of 42 healthy people in their 60s and 70s who showed no signs of decline in mental ability. Before their brains were zapped, participants looked at a series of images: an everyday object, followed briefly by a blank screen, and then either an identical or a modified version of the same object. The goal was to spot whether the two images were different.

Then the participants took the test again, while their brains were stimulated with a current. After about 25 minutes of applying electricity, participants were on average more accurate at identifying changes in the images than they were before the stimulation. Following stimulation, their performance in the test was indistinguishable from that of a group of 42 people in their 20s. And the waves in the prefrontal and temporal cortex, which had previously been out of sync in most of the participants, started to fire in sync, the researchers report today in Nature Neuroscience, a synchronization imperative reminiscent of safeguards that prevent power blackouts on threatened grids. No such effects occurred in a second group of older people who received jolts of current that didn’t synchronize waves in the prefrontal and temporal cortex.

By using bursts of current to knock brain waves out of sync, the researchers also modulated the brain chatter in healthy people in their 20s, making them slower and less accurate at spotting differences in the image test.

“This is a very nice and clear demonstration of how functional connections underlie memory in younger adults and how alterations … can lead to memory reductions in older adults,” says Cheryl Grady, a cognitive neuroscientist at the Rotman Research Institute at Baycrest in Toronto, Canada. It’s also the first time that transcranial stimulation has been shown to restore working memory in older people, says Michael O’Sullivan, a neuroscientist at the University of Queensland in Brisbane, Australia, though electricity in medicine extends far beyond neurostimulation.

But whether brain zapping could turbocharge the cognitive abilities of seniors or help improve the memories of people with diseases like Alzheimer’s is still unclear: In the study, the positive effects on working memory lasted for just under an hour—though Reinhart says that’s as far as they recorded in the experiment. The team didn’t see the improvements decline toward the end, so he suspects that the cognitive boost may last for longer. Still, researchers say much more work has to be done to better understand how the stimulation works.

Clark is optimistic. “No pill yet developed can produce these sorts of effects safely and reliably,” he says. “Helping people is the ultimate goal of all of our research, and it’s encouraging to see that progress is being made.”

Canada expected to miss its 2035 clean electricity goals

Canada 2035 Clean Electricity Target faces a 48.4GW shortfall as renewable capacity lags; accelerating wind, solar PV, grid upgrades, and coherent federal-provincial policy is vital to reach zero-emissions power and strengthen transmission and distribution.

 

Key Points

Canada's plan to supply nearly 100% of electricity from zero-emitting sources by 2035, requiring renewable buildout.

✅ Average adds 2.6GW; shortfall totals 48.4GW by 2035

✅ Expand wind, solar PV, storage, and grid modernization

✅ Align federal-province policy; retire or convert thermal plants

 

GlobalData’s latest report, ‘Canada Power Market Size and Trends by Installed Capacity, Generation, Transmission, Distribution and Technology, Regulations, Key Players and Forecast, 2022-2035’, discusses the power market structure of Canada and, amid looming power challenges, provides historical and forecast numbers for capacity, generation and consumption up to 2035. Detailed analysis of the country’s power market regulatory structure, competitive landscape and a list of major power plants are provided. The report also gives a snapshot of the power sector in the country on broad parameters of macroeconomics, supply security, generation infrastructure, transmission and distribution infrastructure, electricity import and export scenario, degree of competition, regulatory scenario, and future potential. An analysis of the deals in the country’s power sector is also included in the report.

Canada is expected to fall short of its 2035 clean electricity target after reviewing the country’s current renewable capacity activity. The country has targeted to produce nearly 100% of its electricity from zero-emitting sources by 2035, while electricity associations' net-zero goals extend to 2050; however, the country is adding only 2.6GW of annual renewable capacity additions on average every year, which would mean a cumulative shortfall of 48.4GW.

Canada has good governmental support, but it is not doing enough to ensure its targets are met. If the country is to meet its target to produce nearly 100% of electricity from zero-emitting sources by 2035, the country should both increase the capacity and efficiency of renewable power plants, as well as provide comprehensive end-to-end policies at both the federal and provincial levels, as debates over whether Ontario is embracing clean power continue across provinces. It should also involve communities and businesses in raising awareness of the benefits of adopting renewable energy.

The country has a large amount of proven natural gas and oil reserves that are proving too tempting an opportunity, and the Canadian Government is planning to increase the capacity of its gas-based plants under net-zero regulations permit some gas in the power mix, to secure real-time demand and supply. However, the country’s dependency on gas-based plants creates a major challenge to achieve its 2035 clean electricity target.

If the Canadian Government is to meet its 2035 targets, it should draw on examples from its European counterparts and add renewable capacity at a rapid pace, while balancing demand and emissions in key provinces. One advantage for Canada here is that it does not have land constraints, which is common in other major renewable power-generating countries. This could give the country an estimated 6.1GW of renewable capacity every year on average during the 2021-2035 period: enough capacity to meet its target. Most of these installations are expected to be for wind and solar PV.

Changing provincial governments are not helpful when it comes to implementing long-term projects, especially as Ontario faces looming electricity shortfalls that heighten planning risks, and continued stopping and starting of projects like this will only be damaging to renewable goals. Another way the country can achieve its target is by converting thermal power plants into clean energy plants and providing a roadmap or timeline for provinces to retire thermal power plants completely, even as scrapping coal can be costly for some systems.

Canada’s GDP (at constant prices) increased from $1,617.3bn in 2010 to $1,924.5bn in 2021, at a CAGR of 1.6%. The GDP (at constant prices) of the country declined sharply from $1,943.8bn in 2019 to $1,840.5bn in 2020 because of Covid-19 pandemic. After the recommencement of regular industrial and trade activities, the GDP grew by 4.6% in 2021 from 2020. The GDP is expected to cross pre-pandemic levels by the end of 2022.
