Drought threatens Java island's power supply

California Rooftop Solar Cost Shift examines PG&E rate hikes, net metering changes, and utility infrastructure spending impacts on low-income households, distributed generation, and clean energy adoption, potentially raising bills and undermining grid resilience.

Key Points

A claim that rooftop solar shifts fixed grid costs to others; critics cite PG&E rates, avoided costs, and impacts.

✅ PG&E rates outpace national average, underscoring cost drivers.

✅ Net metering cuts risk burdening low- and middle-income homes.

✅ Distributed generation avoids infrastructure spend and grid strain.

California is grappling with soaring electricity prices across the state, with Pacific Gas & Electric (PG&E) rates more than double the national average and increasing at an average of 12.5% annually over the past six years. In response, Governor Gavin Newsom issued an executive order directing state energy agencies to identify ways to reduce power costs. However, recent policy shifts targeting rooftop solar users may exacerbate the problem rather than alleviate it.

The "Cost Shift" Theory

A central justification for these pricing changes is the "cost shift" theory. This theory posits that homeowners with rooftop solar panels reduce their electricity consumption from the grid, thereby shifting the fixed costs of maintaining and operating the electrical grid onto non-solar customers. Proponents argue that this leads to higher rates for those without solar installations.

However, this theory is based on a flawed assumption: that PG&E owns 100% of the electricity generated by its customers and is entitled to full profits even for energy it does not deliver. In reality, rooftop solar users supply only about half of their energy needs and still pay for the rest. Moreover, their investments in solar infrastructure reduce grid strain and save ratepayers billions by avoiding costly infrastructure projects and reducing energy demand growth, aligning with efforts to revamp electricity rates to clean the grid as well.

Impact on Low- and Middle-Income Households

The majority of rooftop solar users are low- and middle-income households. These individuals often invest in solar panels to lower their energy bills and reduce their carbon footprint. Policy changes that undermine the financial viability of rooftop solar disproportionately affect these communities, and efforts to overturn income-based charges add uncertainty about affordability and access.

For instance, Assembly Bill 942 proposes to retroactively alter contracts for millions of solar consumers, cutting the compensation they receive from providing energy to the grid, raising questions about major changes to your electric bill that could follow if their home is sold or transferred. This would force those with solar leases—predominantly lower-income individuals—to buy out their contracts when selling their homes, potentially incurring significant financial burdens.

The Real Drivers of Rising Energy Costs

While rooftop solar users are being blamed for rising electricity rates, calls for action have mounted as the true culprits lie elsewhere. Unchecked utility infrastructure spending has been a significant factor in escalating costs. For example, PG&E's rates have increased rapidly, yet the utility's spending on infrastructure projects has often been criticized for inefficiency and lack of accountability. Instead of targeting solar users, policymakers should scrutinize utility profit motives and infrastructure investments to identify areas where costs can be reduced without sacrificing service quality.

California's approach to addressing rising electricity costs by targeting rooftop solar users is misguided. The "cost shift" theory is based on flawed assumptions and overlooks the substantial benefits that rooftop solar provides to the grid and ratepayers. To achieve a sustainable and equitable energy future, the state must focus on controlling utility spending, promoting clean energy access for all, especially as it exports its energy policies across the West, and ensuring that policies support—not undermine—the adoption of renewable energy technologies.

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 Renewable Energy Jobs rank top 10 in hydropower, says IRENA, but trail in solar PV, wind power, and liquid biofuels; clean tech growth, EV manufacturing, and Canada Infrastructure Bank funding signal broader carbon-neutral opportunities.

Key Points

Canada counts 61,130 clean energy roles, top 10 in hydropower, with potential in solar, wind, biofuels, and EV manufacturing.

✅ 61,130 clean energy jobs in Canada per IRENA

✅ Top 10 share in hydropower employment

✅ Growth expected in solar, wind, biofuels, and EVs

Canada has made the top 10 list of countries for the number of jobs in hydropower, but didn’t rank in three other key renewable energy technologies, according to new international figures.

Although Canada has only two per cent of the global workforce, it had one of the 10 largest slices of the world’s jobs in hydropower in 2019, says the Abu Dhabi-based International Renewable Energy Agency (IRENA)

Canada didn’t make IRENA’s other top-10 employment lists, for solar photovoltaic (PV) technology, where solar power lags by international standards, liquid biofuels or wind power, released Sept. 30. Figures from the agency show the whole sector represents 61,130 jobs across Canada, or 0.5 per cent of the world’s 11.5 million jobs in renewables.

The numbers show Canada needs to move faster to minimize the climate crisis, including by joining trade blocs that put tariffs on high-carbon goods, argued the Victoria-based BC Sustainable Energy Association after reviewing IRENA’s report. The Canadian Renewable Energy Association also said it showed the country has untapped job creation potential, even as growth projections were scaled back after Ontario scrapped a clean energy program.

But other clean tech advocates say there’s more to the story. When tallying clean energy jobs, it's worth a broader look, Clean Energy Canada argued, pointing to the recent Ford-Unifor deal that includes a $1.8-billion commitment to produce electric vehicles in Oakville, Ont.

Natural Resources Minister Seamus O'Regan’s office also pointed out the renewables employment figures from IRENA are proportional to global population. “While Canada's share of the global clean energy job market is in line with our population size, we produce almost 2.7 per cent of the world’s total primary renewable energy supply. As only 0.5 per cent of the global population, we punch above our weight,” said O'Regan's press secretary, Ian Cameron.

Canada joined IRENA in January 2019 and the country has been described by the association as an “important market” for renewables over the long term.

On Thursday, Prime Minister Justin Trudeau announced a new $10-billion “Growth Plan” to be run by the Canada Infrastructure Bank that would include “$2.5 billion for clean power to support renewable generation and storage and to transmit clean electricity between provinces, territories, and regions, including to northern and Indigenous communities.” The infrastructure bank's plan is expected to create 60,000 jobs, the government said, and in Alberta an Alberta renewables surge could power 4,500 jobs as projects scale up.

World ‘building the renewable energy revolution now’

A powerful renewables sector is not just about job creation. It is also imperative if we are to meet global climate objectives, according to the Intergovernmental Panel on Climate Change. Renewable energy sources have to make up at least a 63 per cent share of the global electricity market by mid-century to battle the more extreme effects of climate change, it said.

“The IRENA report shows that people all over of the world are building the renewable energy revolution now,” said Tom Hackney, policy adviser for the BC Sustainable Energy Association.

“Many people in Canada are doing so, too. But we need to move faster to minimize climate change. For example, at the level of trade policy, a great idea would be to develop low-carbon trading blocs that put tariffs on goods with high embodied carbon emissions.”

Canadian Renewable Energy Association president and CEO Robert Hornung said the IRENA jobs review highlights “significant job creation potential” in Canada. As governments explore how to stimulate economic recovery from the impact of the COVID-19 pandemic, said Hornung, it's important to “capitalize on Canada's untapped renewable energy resources.”

In Canada, 82 per cent of the electricity grid is already non-emitting, noted Sarah Petrevan, policy director for Clean Energy Canada.

With the federal government committing to a 90 per cent non-emitting grid by 2030, said Petrevan, more wind and solar deployment can be expected, even though solar demand has lagged in recent years, especially in the Prairies where renewables are needed to help with Canada’s coal-fired power plant phase out.

One example of renewables in the Prairies, where the provinces are poised to lead growth, is the Travers Solar project, which is expected to be constructed in Alberta through 2021, and is being touted as “Canada's largest solar farm.”

But renewables are only “one part of the broader clean energy sector,” said Petrevan. Clean Energy Canada has outlined how Canada could be electric and clean with the right choices, and has calculated clean tech supports around 300,000 jobs, projected to grow to half a million by 2030.

“We’re talking about a transition of our energy system in every sense — not just in the power we produce. So while the IRENA figures provide global context, they reflect only a portion of both our current reality and the opportunity for Canada,” she said.

The organization’s research has shown that manufacturing of electric vehicles would be one of the fastest-growing job creators over the next decade. Putting a punctuation mark on that is a recent $1.8-billion deal with Ford Motor Company of Canada to produce five models of electric vehicles in Oakville, Ont.

China ‘remains the clear leader’ in renewables jobs

With 4.3 million renewable energy jobs in 2019, or 38 per cent of all renewables jobs, China “remains the clear leader in renewable energy employment worldwide,” the IRENA report states. China has the world's largest population and the second-largest GDP.

The country is also by far the world’s largest emitter of carbon pollution, at 28 per cent of global greenhouse gas emissions, and has significant fossil fuel interests. Chinese President Xi Jinping called for a “green revolution” last month, and pledged to “achieve carbon neutrality before 2060.”

China holds the largest proportion of jobs in hydropower, with 29 per cent of all jobs, followed by India at 19 per cent, Brazil at 11 per cent and Pakistan at five per cent, said IRENA.

Canada, with 32,359 jobs in the industry, and Turkey and Colombia hold two per cent each of the world’s hydropower jobs, while Myanmar and Russia hold three per cent each and Vietnam has four per cent.

China also dominates the global solar PV workforce, with 59 per cent of all jobs, followed by Japan, the United States, India, Bangladesh, Vietnam, Malaysia, Brazil, Germany and the Philippines. There are 4,261 jobs in solar PV in Canada, IRENA calculated, and the country is set to hit a 5 GW solar milestone as capacity expands, out of a global workforce of 3.8 million jobs.

In wind power, China again leads, with 44 per cent of all jobs. Germany, the United States and India come after, with the United Kingdom, Denmark, Mexico, Spain, the Philippines and Brazil following suit. Canada has 6,527 jobs in wind power out of 1.17 million worldwide.

As for liquid biofuels, Brazil leads that industry, with 34 per cent of all jobs. Indonesia, the United States, Colombia, Thailand, Malaysia, China, Poland, Romania and the Philippines fill out the top 10. There are 17,691 jobs in Canada in liquid biofuels.

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."

Jersey Electricity Standby Charge proposes a grid-backup fee for commercial self-generators of renewable energy, with a review delaying implementation; potential tariff impacts include 10-15 percent price rises, cost recovery, and network reliability.

Key Points

A grid-backup fee for Jersey self-generating businesses to share network costs fairly and curb electricity price rises.

✅ Applies to commercial self-generation using renewables or not

✅ Excludes full exporters and pre-charge installations

✅ Aims to recover grid costs and avoid 10-15% price rises

Electricity prices could rise by ten to 15 per cent if a standby charge for some commercial customers is not implemented, the chief executive of Jersey Electricity has warned.

Jersey Electricity has proposed extending a monthly fee to commercial customers who generate their own power through renewable means but still wish to be connected to Jersey’s grid as a back-up, echoing Ontario energy storage efforts to shore up reliability.

The States recently unanimously backed a proposal lodged by Deputy Carolyn Labey to delay administering the levy until a review could be carried out, as seen in the UK grid's net-zero transformation debates influencing policy. The charge, was due to be implemented next month but will now not be introduced until May, or later if the review has not concluded.

But Chris Ambler, JE chief executive, warned that failing to implement the standby charge could lead to additional costs for customers.

Some of JE’s commercial customers have already been charged a standby fee after generating their own power through non-renewable means.

The charge does not apply to businesses which export all of their electricity back into the system as part of a buy-back scheme or those which install self-generation facilities before the charge is implemented.

Deputy Labey argued that the Island had done ‘absolutely nothing’ to support the use of renewable energies and instead were discouraging locally generated power by allowing JE to set a standby charge.

She added that she was pleased that the Council of Ministers had already starting reviewing the charges but the debate needed to go ahead to ensure the work continued after the May election.

During a States debate last month, she said: ‘It is increasingly concerning that we, as an island in the 21st century, are happy for our electricity to be provided to us by an unregulated, publicly listed for-profit company with a monopoly on energy.

‘I also think that introducing a charge on renewables at a time when the world is experiencing a revolution in renewable energies, including offshore vessel charging solutions, which are becoming increasingly economic, is something that needs to be investigated.

‘Jersey should be looking to diversify our electricity production and supply, to help protect us from price and currency fluctuations and to ensure that we, as an island, receive the best deal possible for Islanders.’

Mr Ambler said that any price increase would be dependent on the future take-up and use of renewable-energy technology in Jersey.

He said: ‘The cost impact would not be significant in the short term but in the long term it could be significant. I think that we are obliged to let our customers know that.

‘It is very difficult to assess but if we are not able to levy a fair charge, then, as electricity shortages in Canada have shown, we could see prices rise by ten to 15 per cent over time.’

Mr Ambler added that his company was in favour of the use of renewable energy, with a third of the company’s electricity being generated by hydroelectric sources, but that the costs of implementing it needed to be fairly distributed, given how big battery rule changes can affect project viability elsewhere in the market.

And he said that, while it was difficult to quantify how much could be lost if the standby charge was not implemented, it could cost the company over £10 million.

‘In 2014, we only increased our prices by one per cent,’ he said. ‘We are reviewing our prices at the moment but if we did put an increase in place it would be modest and it would not be linked to the standby charge.’

Aurelia Boat Club delivers electric boat membership in Seattle, featuring zero-emission propulsion, quiet cruising, sustainable recreation, and a managed fleet with maintenance, insurance, moorage, and charging handled for members seeking hassle-free, eco-friendly boating.

Key Points

Aurelia Boat Club is a Seattle membership offering all-electric boats, with maintenance, insurance, and moorage included.

✅ Unlimited access to an all-electric fleet

✅ Maintenance, insurance, moorage, and charging included

✅ Quiet, zero-emission cruising on Seattle waters

Seattle's maritime scene has welcomed a new player: Aurelia Boat Club. Founded by former Pure Watercraft employees, Aurelia is poised to redefine electric boating in the city, where initiatives like Washington State Ferries hybrid-electric upgrade are underway. The club's inception follows the unexpected closure of Pure Watercraft, a Seattle-based startup that aimed to revolutionize the pleasure boating industry before its financial troubles led to its downfall.

From Pure Watercraft to Aurelia Boat Club

Pure Watercraft, established in 2011, garnered attention for its innovative electric propulsion systems designed to replace traditional gas-powered motors in boats, while efforts to build the first commercial electric speedboats also advanced. The company attracted significant investment, including a notable partnership with General Motors in 2021, which acquired a 25% stake in Pure Watercraft. Despite these efforts, Pure Watercraft faced financial difficulties and entered receivership in 2024, leading to the liquidation of its assets. 

Amidst this transition, Danylo Kurgan and Mrugesh Desai saw an opportunity to continue the vision of electric boating. Kurgan, formerly a financial analyst at Pure Watercraft and involved in the company's boat club operations, teamed up with Desai, a technology executive and startup investor. Together, they acquired key assets from Pure Watercraft's receivership, including electric outboard motors, pontoon boats, inflatable crafts, battery systems, spare parts, and digital infrastructure. 

Aurelia Boat Club's Offerings

Aurelia Boat Club aims to provide a sustainable and accessible alternative to traditional gas-powered boat clubs in Seattle. Members can enjoy unlimited access to a fleet of all-electric boats without the responsibilities of ownership. The club's boats are equipped with electric motors, offering a quiet and environmentally friendly boating experience, similar to how electric ships are clearing the air on the B.C. coast. Additionally, Aurelia handles maintenance, repairs, insurance, and moorage, allowing members to focus solely on enjoying their time on the water. 

The Future of Electric Boating in Seattle

Aurelia Boat Club's launch signifies a growing interest in sustainable boating practices in Seattle. The club's founders are committed to scaling the business and expanding their fleet to meet the increasing demand for eco-friendly recreational activities, as projects like battery-electric high-speed ferries indicate. By leveraging the assets and knowledge gained from Pure Watercraft, Aurelia aims to continue the legacy of innovation in the electric boating industry.

As the boating community becomes more environmentally conscious, initiatives like Aurelia Boat Club play a crucial role in promoting sustainable practices, and examples such as Harbour Air's electric aircraft highlight the momentum. The club's success could serve as a model for other cities, demonstrating that with the right vision and resources, the transition to electric boating is not only feasible but also desirable.

While the closure of Pure Watercraft marked the end of one chapter, it also paved the way for new ventures like Aurelia Boat Club to carry forward the mission of transforming the boating industry, with regional moves like the Kootenay Lake electric-ready ferry and international innovations such as Berlin electric flying ferry showing what's possible. With a strong foundation and a clear vision, Aurelia is set to make significant waves in Seattle's electric boating scene.
