Raindrop Triboelectric Energy Harvesting converts falling water into electricity using Teflon (PTFE) on indium tin oxide and an aluminum electrode, forming a transient water bridge; a low frequency nanogenerator for renewable, static electricity harvesting.

Key Points

A method using PTFE, ITO, and an aluminum electrode to turn raindrop impacts into low frequency electrical power.

✅ PTFE on ITO boosts charge transfer efficiency.

✅ Water bridge links electrodes for rapid discharge.

✅ Low frequency output suits continuous energy harvesting.

Scientists at the City University of Hong Kong have used a Teflon-coated surface and a phenomenon called triboelectricity to generate a charge from raindrops. “Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene [Teflon] film on an indium tin oxide substrate plus an aluminium electrode,” they explain in their new paper in Nature as a step toward cheap, abundant electricity in the long term.

Triboelectricity itself is an old concept. The word means “friction electricity”—from the Greek tribo, to rub or wear down, which is why a diatribe tires you out—and dates back a long, long time. Static electricity is the most famous kind of triboelectric, and related work has shown electricity from the night sky can be harvested as well in niche setups. In most naturally occurring kinds, scientists have studied triboelectric in order to avoid its effects, like explosions inside of grain silos or hospital workers touching off pure oxygen. (Blowing sand causes an electric field, and NASA even worries about static when astronauts eventually land on Mars.)

One of the most studied forms of intentional and useful triboelectric is in systems such as ocean wave generators where the natural friction of waves meets nanogenerators of triboelectric energy. These even already use Teflon, which has natural conductivity that makes it ideal for this job. But triboelectricity is chaotic, and harnessing it generally involves a bunch of complicated, intersecting variables that can vary with the hourly weather. Promises of static electricity charging devices have often been, well, so much hot, sandy wind.

The scientists at City University of Hong Kong used triboelectric ideas to turn falling raindrops into energy. They say previous versions of the same idea were not very efficient, with materials that didn’t allow for high-fidelity transfer of electrical charge. (Many sources of renewable energy aren’t yet as efficient to turn into power, both because of developing technology and because their renewability means even less efficient use could be better than, for example, fossil fuels, and advances in renewable energy storage could help.)

“[A]chieving a high density of electrical power generation is challenging,” the team explains in its paper. “Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply.” Diversifying how power is generated by water sources such as oceans and rivers is good for the existing infrastructure as well as new installations.

The research team found that as simulated raindrops fell on their device, the way the water accumulated and spread created a link between their two electrodes, one Teflon-coated and the other aluminum. This watery de facto wire link closes the loop and allows accumulated energy to move through the system. Because it’s a mechanical setup, it’s not limited to salty seawater, and because the medium is already water, its potential isn’t affected by ambient humidity either.

Raindrop energy is very low frequency, which means this tech joins many other existing pushes to harvest continuously available, low frequency natural energy, including underwater 'kites' that exploit steady currents. To make an interface that increases “instantaneous power density by several orders of magnitude over equivalent devices,” as the researchers say they’ve done here, could represent a major step toward feasibility in triboelectric generation.

Ontario Nuclear Power Costs highlight LCOE, capex, refurbishment outlays, and waste management, compared with renewables, grid reliability, and emissions targets, informing Australia and Peter Dutton on feasibility, timelines, and electricity prices.

Key Points

They include high capex and LCOE from refurbishments and waste, offset by reliable, low-emission baseload.

✅ Refurbishment and maintenance drive lifecycle and LCOE variability.

✅ High capex and long timelines affect consumer electricity prices.

✅ Low emissions, but waste and safety compliance add costs.

Australian opposition leader Peter Dutton recently lauded Canada’s use of nuclear power as a model for Australia’s energy future. His praise comes as part of a broader push to incorporate nuclear energy into Australia’s energy strategy, which he argues could help address the country's energy needs and climate goals. However, the question arises: Is Ontario’s experience with nuclear power as cost-effective as Dutton suggests?

Dutton’s endorsement of Canada’s nuclear power strategy highlights a belief that nuclear energy could provide a stable, low-emission alternative to fossil fuels. He has pointed to Ontario’s substantial reliance on nuclear power, and the province’s exploration of new large-scale nuclear projects, as an example of how such an energy mix might benefit Australia. The province’s energy grid, which integrates a significant amount of nuclear power, is often cited as evidence that nuclear energy can be a viable component of a diversified energy portfolio.

The appeal of nuclear power lies in its ability to generate large amounts of electricity with minimal greenhouse gas emissions. This characteristic aligns with Australia’s climate goals, which emphasize reducing carbon emissions to combat climate change. Dutton’s advocacy for nuclear energy is based on the premise that it can offer a reliable and low-emission option compared to the fluctuating availability of renewable sources like wind and solar.

However, while Dutton’s enthusiasm for the Canadian model reflects its perceived successes, including recent concerns about Ontario’s grid getting dirtier amid supply changes, a closer look at Ontario’s nuclear energy costs raises questions about the financial feasibility of adopting a similar strategy in Australia. Despite the benefits of low emissions, the economic aspects of nuclear power remain complex and multifaceted.

In Ontario, the cost of nuclear power has been a topic of considerable debate. While the province benefits from a stable supply of electricity due to its nuclear plants, studies warn of a growing electricity supply gap in coming years. Ontario’s experience reveals that nuclear power involves significant capital expenditures, including the costs of building reactors, maintaining infrastructure, and ensuring safety standards. These expenses can be substantial and often translate into higher electricity prices for consumers.

The cost of maintaining existing nuclear reactors in Ontario has been a particular concern. Many of these reactors are aging and require costly upgrades and maintenance to continue operating safely and efficiently. These expenses can add to the overall cost of nuclear power, impacting the affordability of electricity for consumers.

Moreover, the development of new nuclear projects, as seen with Bruce C project exploration in Ontario, involves lengthy and expensive construction processes. Building new reactors can take over a decade and requires significant investment. The high initial costs associated with these projects can be a barrier to their economic viability, especially when compared to the rapidly decreasing costs of renewable energy technologies.

In contrast, the cost of renewable energy has been falling steadily, even as debates over nuclear power’s trajectory in Europe continue, making it a more attractive option for many jurisdictions. Solar and wind power, while variable and dependent on weather conditions, have seen dramatic reductions in installation and operational costs. These lower costs can make renewables more competitive compared to nuclear energy, particularly when considering the long-term financial implications.

Dutton’s praise for Ontario’s nuclear power model also overlooks some of the environmental and logistical challenges associated with nuclear energy. While nuclear power generates low emissions during operation, it produces radioactive waste that requires long-term storage solutions. The management of nuclear waste poses significant environmental and safety concerns, as well as additional costs for safe storage and disposal.

Additionally, the potential risks associated with nuclear power, including the possibility of accidents, contribute to the complexity of its adoption. The safety and environmental regulations surrounding nuclear energy are stringent and require continuous oversight, adding to the overall cost of maintaining nuclear facilities.

As Australia contemplates integrating nuclear power into its energy mix, it is crucial to weigh these financial and environmental considerations. While the Canadian model provides valuable insights, the unique context of Australia’s energy landscape, including its existing infrastructure, energy needs, and the costs of scrapping coal-fired electricity in comparable jurisdictions, must be taken into account.

In summary, while Peter Dutton’s endorsement of Canada’s nuclear power model reflects a belief in its potential benefits for Australia’s energy strategy, the cost-effectiveness of Ontario’s nuclear power experience is more nuanced than it may appear. The high capital and maintenance costs associated with nuclear energy, combined with the challenges of managing radioactive waste and ensuring safety, present significant considerations. As Australia evaluates its energy future, a comprehensive analysis of both the benefits and drawbacks of nuclear power will be essential to making informed decisions about its role in the country’s energy strategy.

Pickering nuclear refurbishment will modernize Ontario's Candu reactors at Pickering B, sustaining 2,000 MW of clean electricity, aiding net-zero goals, and aligning with Ontario Power Generation plans and Canadian Nuclear Safety Commission reviews.

Key Points

An 11-year overhaul of Pickering B Candu reactors to extend life, keep 2,000 MW online, and back Ontario net-zero grid.

✅ 11-year project; 11,000 annual jobs; $19.4B GDP impact.

✅ Refurbishes four Pickering B Candu units; maintains 2,000 MW.

✅ Requires Canadian Nuclear Safety Commission license approvals.

The Ontario government has announced its intention to pursue a Pickering refurbishment at the venerable nuclear power station, which has been operational for over fifty years. This move could extend the facility's life by another 30 years.

This decision is timely, as Ontario anticipates a significant surge in electricity demand and a growing electricity supply gap in the forthcoming years. Additionally, all provinces are grappling with new federal mandates for clean electricity, necessitating future power plants to achieve net-zero carbon emissions.

Todd Smith, the Energy Minister, is expected to endorse Ontario Power Generation's proposal for the plant's overhaul, as per a preliminary version of a government press release.

The renovation will focus on four Candu reactors, known collectively as Pickering B, which were originally commissioned in the early 1980s. This upgrade is projected to continue delivering 2,000 megawatts of power, equivalent to the current output of these units.

According to the press release, the project will span 11 years, create approximately 11,000 annual jobs, and contribute $19.4 billion to Ontario's GDP. However, the total budget for the project remains unspecified.

The project follows the ongoing refurbishment of four units at the nearby Darlington nuclear station, which is more than halfway completed with a budget of $12.8 billion.

The proposal awaits the Canadian Nuclear Safety Commission's approval, and officials face extension request timing considerations before key deadlines.

The Commission is also reviewing a prior request from OPG to extend the operational license of the existing Pickering B units until 2026. This extension would allow the plant to safely continue operating until the commencement of its renovation, pending approval.

Ontario's Ambitious Nuclear Strategy

The announcement regarding Pickering is part of Ontario's broader clean energy plan for an unprecedented expansion of nuclear power in Canada.

Last summer, the province announced its intention to nearly double the output at Bruce Power, currently the world's largest nuclear generating station.

Additionally, Ontario revealed SMR plans to construct three more alongside the existing project at Darlington. These reactors are expected to supply enough electricity to power around 1.2 million homes.

Discussions about revitalizing the Pickering facility began in 2022, after the station had been slated to close as planned amid debate, with Ontario Power Generation submitting a feasibility report to the government last summer.

The Ford government emphasized the necessity of this nuclear expansion to meet the increasing electricity demands anticipated from the auto sector's shift to electric vehicles, the steel industry's move away from coal-fired furnaces, and the growing population in Ontario.

Ontario's capability to attract major international car manufacturers like Volkswagen and Stellantis to produce electric vehicles and batteries is partly attributed to the fact that 90% of the province's electricity comes from non-fossil fuel sources.

German Energy Price Brakes harness price signals in a market-based policy, cutting gas consumption, preserving industrial output, and supporting CO2 reduction, showcasing Germany's resilience and adaptation while protecting households and businesses across Europe.

Key Points

Fixed-amount subsidies preserving price signals to curb gas use, shield consumers, and sustain industrial output.

✅ Maintains incentives via market-based price signals

✅ Cuts gas consumption without distorting EU markets

✅ Protects households and industry while curbing CO2

German industry and society are once again proving much more resilient and adaptable than certain people feared. Horror scenarios of a dangerous energy rationing or a massive slump in our economy have often been bandied about. But we are nowhere near that. With a challenging year just behind us, this is good news — not only for Germany, but also for Europe, where France-Germany energy cooperation has strengthened solidarity.

Companies and households reacted swiftly to the sharp increases in energy prices, in line with momentum in the global energy transition seen across markets. They installed more efficient heating or production facilities, switched to alternatives and imported intermediate products. The results are encouraging: German households and businesses have reduced gas consumption significantly, despite recent cold weather. From the start of the war in Ukraine to mid-December industrial gas consumption in Germany was (temperature-adjusted) around 20 per cent lower than the average level for the preceding three years. Even if some firms have cut back production, especially in energy-intensive sectors, industrial output as a whole has only fallen by about 1 per cent since the start of 2022. Added to this, in a survey released by the Ifo institute in November, over a third of German companies saw the potential to reduce gas consumption further without endangering output.

Instead of imposing excessive laws and regulations, we have relied on price signals and the prudence of market participants to create the right incentives and reduce gas consumption, as falling costs like record-low solar power prices continue to reinforce those signals across sectors.

We will follow this approach in coming months, when energy savings will remain important, even as the EU electricity outlook anticipates sharply higher demand by 2050. Our latest relief measures will not distort price signals. To this end, the Bundestag approved gas and electricity price brakes in its final session in 2022. They are designed to function without any intervention in markets or prices. This system will pay out a fixed amount relative to previous years’ consumption and the current difference to a reference price — regardless of current consumption.

Energy price brakes are the main component of Germany’s “protective shield”, which makes up to €200bn available for measures in 2022 to 2024. Seen in relation to the German economy’s size, its past heavy reliance on Russian energy imports and the fact that the measures will expire in 2024, these are balanced and expedient mechanisms. In contrast to instruments used in other countries, our new arrangements will not affect the price formation process driven by supply and demand, or on incentives to save gas. Companies and households will continue to save the full market price when they reduce consumption by a unit of gas or electricity. In this way, the price brakes also avoid the creation of additional demand for gas at the expense of consumers in other European countries, even as Europe’s Big Oil turning electric signals broader structural shifts in energy markets. No one need fear that competition will be distorted or that gas will be bought up. Indeed, a recent IMF working paper on cushioning the impact of high energy prices on households explicitly praises the German energy price brakes.

Current developments confirm the effectiveness of a market-based approach — and show that we should also rely on price signals when it comes to reducing CO₂ emissions, as suggested by IEA CO2 trends in recent years. Last year, households and companies had only a few weeks to adapt, yet we have already seen a strong response. The effect of CO₂ prices can be even stronger, as adaptation is possible over a much longer time and they additionally affect expectations and long-term decisions. Regulatory interventions and subsidy schemes, even if well targeted, cannot compete with market co-ordination and incentives that support individual decision-making and promote innovation.

Europe and Germany can weather this crisis without a collapse in industrial production. We also have an opportunity to deal efficiently with the move to climate neutrality, aligned with Germany’s hydrogen strategy for imported low-carbon fuels. In both cases, we should have confidence in price signals as well as in the power of people and business to innovate and adapt.

Florida Solar for All Opt-Out highlights Gov. DeSantis rejecting EPA grant funds under the Inflation Reduction Act, limiting low-income households' access to solar panels, clean energy programs, and promised electricity savings across disadvantaged communities.

Key Points

Florida Solar for All Opt-Out is the state declining EPA grants, restricting low-income access to solar energy savings.

✅ EPA grant under IRA aimed at low-income solar

✅ Estimated 20% electricity bill savings missed

✅ Florida lacks PPAs and renewable standards

Florida has passed up on up to $400 million in federal money that would have helped low-income households install solar panels.

A $7 billion grant “competition” to promote clean energy in disadvantaged communities by providing low-income households with access to affordable solar energy was introduced by President Joe Biden earlier this year, and despite his climate law's mixed results in practice, none of that money will reach Florida households.

The Environmental Protection Agency announced the competition in June as part of Biden’s Inflation Reduction Act. However, Florida Gov. Ron DeSantis has decided to pass on the $400 million up for grabs by choosing to opt out of the opportunity.

Inflation Reduction Act:What is the Inflation Reduction Act? Everything to know about one of Biden's big laws

The program would have helped Florida households reduce their electricity costs by a minimum of 20% during a key time when Floridians are leaving in droves due to a rising cost of living associated with soaring insurance costs, inflation, and proposed FPL rate hikes statewide.

Florida was one of six other states that chose not to apply for the money.

President Joe Biden announced a $7 billion “competition” to promote clean energy in disadvantaged communities.

The opportunity, named “Solar for All,” was announced by the EPA in June and promised to provide up to $7 billion in grants to states, territories, tribal governments, municipalities, and nonprofits to expand the number of low-income and disadvantaged communities primed for residential solar investment — enabling millions of low-income households to access affordable, resilient and clean solar energy.

The grant is intended to help lower energy costs for families, create jobs and help reduce greenhouse effects that accelerate global climate change by providing financial support and incentives to communities that were previously locked out of investments.

How much money would Floridians save under the ‘Solar for All’ solar panel grant?

The program aims to reduce household electricity costs by at least 20%. Florida households paid an average of $154.51 per month for electricity in 2022, just over 14% of the national average of $135.25, and debates over hurricane rate surcharges continue to shape customer bills, according to the U.S. Energy Information Administration. A 20% savings would drop those bills down to around $123 per month.

On the campaign trail, DeSantis has pledged to unravel Biden’s green energy agenda if elected president, amid escalating solar policy battles nationwide, slamming the Inflation Reduction Act and what he called “a concerted effort to ramp up the fear when it comes to things like global warming and climate change.”

His energy agenda includes ending Biden’s subsidies for electric cars while pushing policies that he says would ramp up domestic oil production.

“The subsidies are going to drive inflation higher,” DeSantis said at an event in September. “It’s not going to help with interest rates, and it is certainly not going to help with our unsustainable debt levels.”

DeSantis heading to third debate:As he enters third debate, Ron DeSantis has a big Nikki Haley problem

DeSantis’ plan to curb clean energy usage in Florida seems to be at odds with the state as a whole, and the region's evolving strategy for the South underscores why it has been ranked among the top three states to go solar since 2019, according to the Solar Energy Industries Association (SEIA).

SEIA also shows, however, that Florida lags behind many other states when it comes to solar policies, as utilities tilt the solar market in ways that influence policy outcomes statewide. Florida, for instance, has no renewable energy standards, which are used to increase the use of renewable energy sources for electricity by requiring or encouraging suppliers to provide customers with a stated minimum share of electricity from eligible renewable resources, according to the EIA.

Power purchase agreements, which can help lower the cost of going solar through third-party financing, are also not allowed in Florida, with court rulings on monopolies reinforcing the existing market structure. And there have been other policies implemented that drove other potential solar investments to other states.

Seattle Capitol Hill Apartment Fire highlights an electrical fire from an overheated power strip, a two-alarm response by 70 firefighters, safe evacuation, displaced resident aid, and prevention tips like smoke detectors and load limits.

Key Points

Two-alarm early-morning blaze in Seattle traced to an overheated power strip, displacing one resident and injuring none.

✅ Origin: overheated power strip ignited nearby combustibles

✅ Response: 70 firefighters, two-alarm, rapid containment

✅ Safety: avoid overloads; inspect cords; use smoke detectors

An early-morning fire in Seattle’s Capitol Hill neighborhood severely damaged a three-story apartment building, displacing one resident. The blaze, which broke out around 4:34 a.m. on a Friday, drew more than 70 firefighters to the scene, as other critical sectors have implemented on-site staffing during outbreaks to maintain operations, and was later traced to an overheated power strip.

The Fire Incident

The Seattle Fire Department responded to the fire, which had started on the second floor of the building in the 1800 block of 12th Avenue. Upon arrival, crews were met with heavy smoke and flames coming from one unit. The fire quickly spread to a unit on the third floor, prompting the Seattle Fire Department to escalate their response to a two-alarm fire due to its size and the potential threat to nearby structures.

Firefighters initially attempted to contain the blaze from the exterior before they moved inside the building to fully extinguish the fire. Thankfully, the fire was contained to the two affected units, preventing the destruction of the remaining seven apartments in the building.

All residents safely evacuated the building on their own. Despite the substantial damage to the two apartments, no injuries were reported. One resident was displaced by the fire and was assisted by the Red Cross in finding temporary accommodation.

Cause of the Fire

Investigators later determined that the fire was accidental, most likely caused by an overheated electrical power strip. The power strip had reportedly ignited nearby combustible materials, sparking the flames that quickly spread throughout the unit. Although the exact details are still under investigation, the fire serves as a stark reminder of the potential risks associated with overloaded or damaged electrical equipment and how electrical safety knowledge gaps can contribute to incidents.

The Risks of Power Strips

Power strips, while essential for providing multiple outlets, can pose a serious fire hazard if used improperly, and specialized arc flash training in Vancouver underscores the importance of understanding electrical hazards across settings.

This fire in Seattle highlights the importance of maintaining electrical devices and following proper usage guidelines. According to experts, it is crucial to regularly inspect power strips for any visible damage, such as frayed cords or scorch marks, and to replace them if necessary. It's also advisable to avoid using power strips with high-power appliances like space heaters, microwaves, or refrigerators.

Impact and Community Response

The fire has raised awareness about the dangers of electrical hazards in residential buildings, especially in older apartment complexes where wiring systems may not be up to modern standards. Local authorities and fire safety experts are urging residents to review safety guidelines and ensure that their living spaces are free from potential fire hazards and to avoid dangerous stunts at dams and towers that can lead to serious injuries.

Seattle's fire department, which responded to this incident, continues to emphasize fire prevention and safety education. This event also highlights the importance of having working smoke detectors and clear escape routes in apartment buildings, and ongoing fire alarm training can improve system reliability. The Seattle Fire Department recommends that all tenants know the locations of fire exits and practice safe evacuation procedures, especially in high-rise or multi-unit buildings.

Additionally, the Red Cross has stepped in to assist the displaced resident. The organization provides temporary shelter, food, and financial aid for those affected by disasters like fires. The fire underscores the importance of having emergency preparedness plans in place and the need for immediate relief for those who lose their homes in such incidents.

The Seattle apartment fire, which displaced one resident and caused significant damage to two units, serves as a reminder of the potential dangers associated with improperly maintained or overloaded electrical devices, especially power strips, and how industry recognition, such as a utility safety award, reinforces best practices. While the cause of this fire was linked to an overheated power strip, it could have easily been prevented with regular inspections and safer practices.

As fire departments continue to respond to similar incidents, it is critical for residents to stay informed about fire safety, particularly regarding electrical equipment and outdoor hazards like safety near downed power lines in storm conditions. Awareness, proper maintenance, and following safety protocols can significantly reduce the risk of electrical fires and help protect residents from harm.
