GE Global Research, the technology development arm of the General Electric Company, announced a battery-free, multi-detection radio-frequency identification (RFID) sensing platform that could enable a wide range of low cost wireless sensing products in healthcare, security, food packaging, water treatment and pollution prevention.

GE's unique RFID sensors are built on traditional RFID tags.

This “first-of-its-kind” sensing platform, in which a single sensor can provide a highly selective response to multiple chemicals under variable conditions, operates without a battery. GE’s sensor technology overcomes limitations in today’s sensors such as inadequate response selectivity and the need for an on-board power source. Without a battery, new sensors can be designed to be smaller than a penny and manufactured at very low cost. This could enable many exciting product applications, including:

• New security sensors that more effectively can detect dangerous chemical and biological threats;

• In-the-field water purification monitoring, checking for water impurities;

• Food and beverage safety monitoring, measuring the freshness of goods in transport or that are stored in the refrigerator at home;

• Portable vaccine manufacturing, ensuring the purity of a vaccine manufactured on-site during an emergency response to a flu outbreak or other potential pandemic;

• Emissions monitoring at power plants.

Radislav Potyrailo, a principal scientist at GE Global Research who leads this multidisciplinary wireless sensing development team, said, “We believe GE’s battery-free wireless sensing platform will be a game-changer across many product platforms in healthcare, security, water and pollution prevention, to name a few. Without the need for batteries, we can make sensors that are much smaller in size and at substantially reduced costs. These attributes, combined with the sensors’ highly selective chemical and bio sensing capabilities, provide new breakthrough sensing opportunities that will open the door to many new, innovative applications.”

Potyrailo added, "Because these sensors can be made at such low cost, they also can be made for one-time use. Similar to how your groceries get scanned for a price, imagine pointing a handheld sensor reader at a milk carton or packaged food to see whether it has been spoiled. This is just one of the new applications you can begin to consider with disposable, low cost multi-detection RFID sensors."

These new RFID sensors use a conventional RFID tag, but are coated with a chemically or biologically sensitive film. The sensor reader can obtain several varied responses, which allows the sensor to identify and measure individual chemicals in different mixtures and variable conditions. GEÂ’s sensors can detect trace concentrations of toxic gases such as toxic industrial chemicals (TICs), volatile organic compounds (VOCs), and chemicals in liquids.

To operate without batteries, the power is obtained wirelessly from the sensor reader. The reader activates the sensor antenna and the RFID chip and collects several response data parameters. The measurement of these parameters provides the ability to selectively detect different chemicals with an individual sensor.

The development of GEÂ’s novel wireless sensing platform illustrates the power of GE technology to leverage multiple areas of technical expertise from across many disciplines represented at GEÂ’s Global Research Center. A multidisciplinary team comprised of analytical chemists, RF engineers, polymer scientists, and microfabrication engineers contributed to the development of this new platform.

UK Anticipates a 16% Decrease in Energy Bills in April

UK Energy Price Cap Cut 2024 signals relief as wholesale gas prices fall; Ofgem price cap drops per Cornwall Insight, aided by LNG supply, mild winter, despite Red Sea tensions and Ukraine conflict impacts.

 

Key Points

A forecast cut to Great Britain's Ofgem price cap as wholesale gas falls, easing typical annual household bills in 2024.

✅ Cap falls from £1,928 to £1,620 in April 2024

✅ Forecast £1,497 in July, then about £1,541 from October

✅ Drivers: lower wholesale gas, LNG supply, mild winter

 

Households in Great Britain are set to experience a significant reduction in energy costs this spring, with bills projected to drop by over £300 annually. This decrease is primarily due to a decline in wholesale gas prices, offering some respite to those grappling with the cost of living crisis.

Cornwall Insight, a well-regarded industry analyst, predicts a 16% reduction in average bills from the previous quarter, potentially reaching the lowest levels since the onset of the Ukraine conflict.

The industry’s price cap, indicative of the average annual bill for a typical household, is expected to decrease from the current £1,928, set earlier this month, to £1,620 in April – a reduction of £308 and £40 less than previously forecasted in December, as ministers consider ending the gas-electricity price link to improve market resilience.

Concerns about escalating tensions in the Red Sea, where Houthi rebels have disrupted global shipping, initially led analysts to fear an increase in wholesale oil prices and subsequent impact on household energy costs.

Contrary to these concerns, oil prices have remained relatively stable, and European gas reserves have been higher than anticipated during a mild winter, with European gas prices returning to pre-Ukraine war levels since November.

Cornwall Insight anticipates that energy prices will continue to be comparatively low through 2024. They predict a further decline to £1,497 for a typical annual bill from July, followed by a slight increase to £1,541 starting in October.

This forecast is a welcome development for Britons who have been dealing with increased expenses across various sectors, from food to utilities, amidst persistently high inflation rates, with energy-driven EU inflation hitting lower-income households hardest across member states.

Energy bills saw a steep rise in 2021, which escalated further due to the Ukraine conflict in 2022, driving up wholesale gas prices. This surge prompted government intervention to subsidize bills, with the UK price cap estimated to cost around £89bn to the public purse, capping costs to a typical household at £2,500.

Cornwall Insight noted that the supply of liquified natural gas to Europe had not been as adversely affected by the Red Sea disruptions as initially feared. Moreover, the UK has been well-supplied with gas from the US, which has become a more significant supplier since the Ukraine war, even as US electricity prices have risen to multi-decade highs. Contributing factors also include lower gas prices in Asia, mild weather, and robust gas availability.

Craig Lowrey, a principal consultant at Cornwall Insight, remarked that concerns about Red Sea events driving up energy prices have not materialized, allowing households to expect a reduction in prices.

On Monday, the next-month wholesale gas price dropped by 4% to 65p a therm.

However, Lowrey cautioned that a complete return to pre-crisis energy bill levels remains unlikely due to ongoing market impacts from shifting away from Russian energy sources and persistent geopolitical tensions, as well as policy changes such as Britain’s Energy Security Bill shaping market reforms.

Richard Neudegg, director of regulation at Uswitch, welcomed the potential further reduction of the price cap in April. However, he pointed out that this offers little solace to households currently struggling with high winter energy costs during the winter. Neudegg urged Ofgem, the energy regulator, to prompt suppliers to reintroduce more competitive and affordable fixed-price deals.

Trump's Canada Tariff May Spike NY Energy Prices

25% Tariff on Canadian Imports threatens New York energy markets, disrupting hydroelectric power and natural gas supply chains, raising electricity prices, increasing gas costs, and intensifying trade tensions, policy uncertainty, and cross-border logistics risks.

 

Key Points

A U.S. policy imposing 25% duties on Canadian goods, risking higher New York electricity and natural gas costs.

✅ Hydroelectric and gas imports face costlier cross-border flows

✅ Higher utility bills for NY households and businesses

✅ Supply chain volatility and policy uncertainty increase

 

President Donald Trump announced the imposition of a 25% tariff on all imports from Canada, citing concerns over drug trafficking and illegal immigration. This decision has raised significant concerns among experts and residents in New York, who warn that the tariff could lead to increased electricity and gas prices in the state.

Impact on New York's Energy Sector

New York relies heavily on energy imports from Canada, particularly electricity and natural gas. Canada is a major supplier of hydroelectric power to the northeastern United States, including New York, with its electricity exports at risk amid trade tensions. The imposition of a 25% tariff on Canadian goods could disrupt this supply chain, leading to higher energy costs for consumers and businesses in New York. Justin Wilcox, an energy analyst, stated, "If the tariff is implemented, it could lead to increased costs for electricity and gas, affecting both consumers and businesses."

Potential Economic Consequences

The increased energy costs could have broader economic implications for New York, and some experts advise against cutting Quebec's exports to avoid exacerbating market volatility. Higher electricity and gas prices may lead to increased operational costs for businesses, potentially resulting in higher prices for goods and services, while tariff threats have boosted support for Canadian energy projects that could reshape regional supply. This could exacerbate the cost-of-living challenges faced by residents and strain the state's economy.

Political and Diplomatic Reactions

The tariff has also sparked political and diplomatic reactions, including threats to cut U.S. electricity exports from Ontario that raised tensions. New York Governor Kathy Hochul expressed concern over the potential economic impact, stating, "We are closely monitoring the situation and are prepared to take necessary actions to protect New York's economy." Additionally, Canadian officials have expressed their disapproval of the tariff, and Ontario Premier Doug Ford's Washington meeting underscored ongoing discussions, emphasizing the importance of the trade relationship between the two countries.

Historical Context

This development is part of a broader pattern of trade tensions between the United States and its neighbors. In 2018, the U.S. imposed tariffs on Canadian steel and aluminum, leading to retaliatory measures from Canada. The current situation underscores the ongoing challenges in international trade relations, where a recent tariff threat delayed Quebec's green energy bill and highlighted the potential domestic impacts of such policies.

The imposition of a 25% tariff on Canadian imports by President Trump has raised significant concerns in New York regarding potential increases in electricity and gas prices. Experts warn that this could lead to higher costs for consumers and businesses, with broader economic implications for the state. As the situation develops, it will be crucial to monitor the responses from both state and federal officials, as well as how Canadians support tariffs on energy and minerals may influence policy, and the potential for diplomatic negotiations to address these trade tensions.

Ontario Providing Support for Industrial and Commercial Electricity Consumers During COVID-19

Ontario Global Adjustment Deferral provides COVID-19 relief to industrial and commercial electricity consumers, holding GA charges at pre-COVID levels, aligning Class A and Class B rates, and deferring non-RPP costs from April to June 2020.

 

Key Points

An emergency measure that defers a portion of GA charges to stabilize electricity bills for non-RPP Class A/B consumers.

✅ Holds GA near pre-COVID levels at $115/MWh for Class B.

✅ Applies equal percentage relief to Class A customers.

✅ Deferred costs recovered over 12 months from Jan 2021.

 

Through an emergency order passed today, the Ontario government is taking steps to defer a portion of Global Adjustment (GA) charges for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan for the period starting from April 2020, at a time when Toronto's growing electricity needs require careful planning. This initiative is intended to provide companies with temporary immediate relief on their monthly electricity bills, as utilities use AI to adapt to shifting electricity demands in April, May and June 2020. The government intends to keep this emergency order in place until May 31, 2020, and subsequent regulatory amendments would, if approved, provide for the deferral of these charges for June 2020 as well.

This relief will prevent a marked increase in Global Adjustment charges due to the low electricity demand caused by the COVID-19 outbreak. Without this emergency order, a small industrial or commercial consumer (i.e., Class B) could have seen bills increase by 15 per cent or more. This emergency order will hold GA rates in line with pre-COVID-19 levels, even as clean energy initiatives in British Columbia accelerate across the sector.

"Ontario's industrial and commercial electricity consumers are being impacted by COVID-19. They employ thousands of hardworking Ontarians, and we know this is a challenging time for them," said Greg Rickford, Minister of Energy, Northern Development and Mines. "This would provide immediate financial support for more than 50,000 companies when they need it most: as they do their part to stop the spread of COVID-19 and as they prepare to help get our economy moving again with Toronto preparing for a surge in electricity demand in the years ahead."

Quick Facts

  • The GA rate for smaller industrial and commercial consumers (i.e., Class B) has been set at $115 per megawatt-hour, which is roughly in line with the March 2020 value, alongside efforts to develop IoT security standards for electricity sector devices today. Large industrial and commercial consumers (i.e., Class A) will receive the same percentage reduction in GA charges as Class B consumers.
  • Subject to the approval of subsequent amendments, deferred costs would be recovered over a 12-month period beginning in January 2021, amid increasing exposure to harsh weather across Canadian grids.

Perry presses ahead on advanced nuclear reactors

Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.

 

Key Points

Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.

✅ DOE test facility at Idaho National Laboratory

✅ Small modular reactors with passive safety systems

✅ University simulators train next-gen nuclear operators

 

Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.

The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.

“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.

With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.

A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.

“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.

The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.

On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.

The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.

NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”

California Halts Energy Rebate Program Amid Trump Freeze

California energy rebate freeze disrupts heat pump incentives, HVAC upgrades, and climate funding, as federal uncertainty stalls Inflation Reduction Act support, delaying home electrification, energy efficiency gains, and greenhouse gas emissions reductions statewide.

 

Key Points

A statewide pause on $290M incentives for heat pumps and HVAC upgrades due to federal climate funding uncertainty.

✅ $290M program paused amid federal funding freeze

✅ Heat pump, HVAC, electrification upgrades delayed

✅ Previously approved rebates honored; new apps halted

 

California’s push for a more energy-efficient future has hit a significant roadblock as the state pauses a $290 million rebate program aimed at helping homeowners replace inefficient heating and cooling systems with more energy-efficient alternatives. The California Energy Commission announced the suspension of the program, citing uncertainty stemming from President Donald Trump’s decision to freeze funding for various climate-related initiatives.

The Halted Program

The energy rebate program, which utilizes federal funding to encourage the use of energy-efficient appliances such as heat pumps, was a crucial part of California’s efforts to reduce energy consumption and greenhouse gas emissions. By providing financial incentives for homeowners to upgrade to more efficient heating and cooling systems, the program aimed to make green energy solutions more accessible and affordable to residents. The rebate program had been popular, with many homeowners eager to participate in the initiative to lower their energy costs and improve the sustainability of their homes.

However, due to the uncertainty surrounding federal funding, the California Energy Commission announced on Monday that it would no longer be accepting new applications for the program. The agency did clarify that it would continue to honor rebates for applications that had already been approved. The pause will remain in effect until the Trump administration provides more clarity regarding the program's future funding.

The Trump Administration’s Role

This move highlights a broader issue regarding access to federal funding for state-level energy programs. The Trump administration’s decision to freeze funding for climate-related initiatives has left many states in limbo, as previously approved federal money has not been distributed as expected. Despite federal court rulings directing the Trump administration to restore these funds, states like California are still struggling to navigate the uncertainty of climate-related financial support from the federal government.

California’s decision to pause the rebate program comes after similar actions by other states. Arizona paused a similar program just a week prior, and Rhode Island had already paused new applications earlier this year. These states are all recipients of funding from a larger $4.3 billion initiative under the Inflation Reduction Act, which is designed to help homeowners purchase energy-efficient appliances like heat pumps, water heaters, and electric cooktops.

Impact of the Freeze

The pause of California's rebate program has serious implications for both consumers and the state’s energy goals. For residents, the halt means delays in the ability to upgrade to more energy-efficient home systems, which could lead to higher energy costs in the short term, a concern amid soaring electricity prices across the state.

The $290 million program was a significant step in encouraging homeowners to invest in energy efficiency, and its suspension leaves a gap in the availability of resources for those who were hoping to make energy-saving upgrades. Many of these upgrades are not just beneficial to homeowners, but they also contribute to the state’s overall energy efficiency goals, helping to reduce reliance on non-renewable energy sources, even as California's dependence on fossil fuels persists, and decrease greenhouse gas emissions.

Federal and State Tensions

The freeze in funding is just one of many points of tension between the Trump administration and states like California, which have pursued aggressive environmental policies aimed at reducing emissions and combating climate change. California has often found itself at odds with the federal government on environmental issues, especially under the leadership of President Trump. The state’s ambitious environmental policies have sometimes clashed with the federal government's approach, including efforts to wind down its fossil fuel industry in line with climate goals.

In this case, the freeze on climate-related funding appears to be part of a broader strategy by the Trump administration to limit federal spending on environmental programs, and as regulators weigh whether the state may need more power plants, planning remains complex. While the freeze impacts states that are working to transition to clean energy, critics argue that such moves undermine efforts to tackle climate change and could slow down progress toward a greener future.

The Path Forward

For California, the next steps will depend heavily on the actions of the federal government. While the state can continue to push for climate funding in the courts, the lack of clarity around the release of federal funds creates uncertainty for state programs that rely on these resources. As California continues to navigate this funding freeze, it will need to explore alternative solutions to keep its energy efficiency programs on track, such as efforts to revamp electricity rates to clean the grid, even in the face of federal challenges.

In the meantime, California residents and homeowners who were hoping to take advantage of the rebate program may have to wait until further clarification from the federal government is provided, even as officials warn of a looming electricity shortage in coming years. Whether the program can be restored or expanded in the future remains to be seen, but for now, the pause serves as a reminder of the ongoing struggles that states face when dealing with shifting federal priorities.

As the issue unfolds, other states facing similar challenges may take cues from California’s actions, and with California exporting energy policies to Western states, broader conversations about how federal and state governments can collaborate to ensure that energy efficiency initiatives and climate goals are not sidelined due to political or budgetary differences.

California’s decision to pause its $290 million energy rebate program is a significant development in the ongoing struggle between state and federal governments over climate-related funding. The uncertainty created by the Trump administration’s freeze on energy efficiency programs has led to disruptions in state-level efforts to promote sustainability and reduce emissions. As the situation continues to evolve, both California and other states will need to consider how to move forward without relying on federal funding that may or may not be available in the future.

Ontario Energy Board prohibiting electricity shutoffs during latest stay-at-home order

OEB Disconnection Ban shields Ontario residential customers under the stay-at-home order, pausing electricity distributor shutoffs for non-payment and linking COVID-19 Energy Assistance Program credits for small businesses, charities, and overdue utility bills.

 

Key Points

A pause on electricity shutoff notices during Ontario's stay-at-home order, with COVID-19 bill credits for customers.

✅ Distributors cannot issue residential disconnection notices.

✅ Applies through the stay-at-home order timeline.

✅ CEAP credits: $750 residential; $1,500 small biz and charities.

 

With Ontario now into the third province-wide lockdown, the Ontario Energy Board (OEB) has promised residents won't have to worry about their power being shut off.

On April 8, the Province issued the third stay-at-home order in the last 13 months which is scheduled to last for 28 days until at least May 6, as electricity rates and policies continue to shift.

On April 30, the annual winter disconnection ban is set to expire, meaning electricity distributors like Hydro One would normally be permitted to issue disconnection notices for non-payment as early as 14 days before the end of the ban.

However, the OEB has announced changes for electricity consumers that prohibit electricity distributors from issuing disconnection notices to residential customers for the entirety of the stay-at-home order.

Additionally, the COVID-19 Energy Assistance Program is available for residential, small business, and registered charity customers who have overdue amounts on their electricity or gas bills as a result of the pandemic, complementing support for electric bills introduced during COVID-19, and the fixed COVID-19 hydro rate that helped stabilize costs.

Those who meet these criteria are eligible for credits up to a maximum of $750 for residential customers and $1,500 for small businesses and charities, alongside earlier moves to set an off-peak price to ease costs.
