The cells that make up solar panels can draw insects from their breeding sites, fooling them into believing they're laying their eggs in a safe place, a new study finds.

Instead, the eggs fail to hatch, jeopardizing the reproduction of a variety of insects.

Research from the Michigan State University finds that the shiny black solar cells that use the sun's rays to create energy are also highly attractive to aquatic insects as they reflect sunlight, creating polarized light. Because polarized light is the way insects identify the surface of water, many, such as mayflies, mistakenly believe the panels are water and deposit eggs on the surface of the panels.

"This research demonstrates that solar panels are a strong new source of polarized light pollution that creates ecological traps for many types of insect," said Bruce Robertson, a research associate at Michigan State University's Kellogg Biological Station, in a release.

"This is of significant conservation importance given the radical expansion in solar energy development and the strong negative impacts of ecological traps on animal populations."

The study finds that the addition of white grids to the surface of the panels - or other methods of breaking up the polarized reflection of light - could reduce this problem. However, the white strips could potentially reduce energy generation by about 1.8 per cent.

New England takes key step to 1.2 GW of Quebec hydro as Maine approves transmission line

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

 

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

 

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​

Washington AG Leads Legal Challenge Against Trump’s Energy Emergency

Washington-Led Lawsuit Against Energy Emergency challenges President Trump's executive order, citing state rights, environmental reviews, permitting, and federal overreach; coalition argues record energy output undermines emergency claims in Seattle federal court.

 

Key Points

Multistate suit to void Trump's energy emergency, alleging federal overreach and weakened environmental safeguards.

? Challenges executive order's legal basis and scope

? Claims expedited permitting skirts environmental reviews

? Seeks to halt emergency permits for non-emergencies

 

In a significant legal move, Washington State Attorney General Nick Brown has spearheaded a coalition of 15 states in filing a lawsuit against President Donald Trump's executive order declaring a national energy emergency. The lawsuit, filed in federal court in Seattle on May 9, 2025, challenges the legality of the emergency declaration, which aims to expedite permitting processes for fossil fuel projects in pursuit of an energy dominance vision by bypassing key environmental reviews.

Background of the Energy Emergency Declaration

President Trump's executive order, issued on January 20, 2025, asserts that the United States faces an inadequate and unreliable energy grid, particularly affecting the Northeast and West Coast regions. The order directs federal agencies, including the Army Corps of Engineers and the Department of the Interior, to utilize "any lawful emergency authorities" to facilitate the development of domestic energy resources, with a focus on oil, gas, and coal projects. This includes expediting reviews under the Clean Water Act, Endangered Species Act, the National Environmental Policy Act, and the National Historic Preservation Act, potentially reducing public input and environmental oversight.

Legal Grounds for the Lawsuit

The coalition of states, led by Washington and California, argues that the emergency declaration is an overreach of presidential authority, echoing disputes over the Affordable Clean Energy rule in federal courts. They contend that U.S. energy production is already at record levels, and the declaration undermines state rights and environmental protections. The lawsuit seeks to have the executive order declared unlawful and to halt the issuance of emergency permits for non-emergency projects. 

Implications for Environmental Protections

Critics of the energy emergency declaration express concern that it could lead to significant environmental degradation. By expediting permitting processes, including geothermal permitting, and reducing public participation, the order may allow projects to proceed without adequate consideration of their impact on water quality, wildlife habitats, and cultural resources. Environmental advocates argue that such actions could set a dangerous precedent, enabling future administrations to bypass essential environmental safeguards under the guise of national emergencies, even as the EPA advances new pollution limits for coal and gas plants to address the climate crisis.

Political and Legal Reactions

The Trump administration defends the executive order, asserting that the president has the authority to declare national emergencies and that the energy emergency is necessary to address perceived deficiencies in the nation's energy infrastructure and potential electricity pricing changes debated by industry groups. However, legal experts suggest that the broad application of emergency powers in this context may face challenges in court. The outcome of the lawsuit could have significant implications for the balance of power between state and federal authorities, as well as the future of environmental regulations in the United States.

The legal challenge led by Washington State Attorney General Nick Brown represents a critical juncture in the ongoing debate over energy policy and environmental protection. As the lawsuit progresses through the courts, it will likely serve as a bellwether for future conflicts between state and federal governments regarding the scope of executive authority and the preservation of environmental standards, amid ongoing efforts to expand uranium and nuclear energy programs nationwide. The outcome may set a precedent for how national emergencies are declared and managed, particularly concerning their impact on state governance and environmental laws.

Texas Utilities back out of deal to create smart home electricity networks

Smart Meter Texas real-time pricing faces rollback as utilities limit on-demand reads, impacting demand response, home area networks, ERCOT wholesale tracking, and thermostat automation, reducing efficiency gains promised through deregulation and smart meter investments.

 

Key Points

A plan linking smart meters to ERCOT prices, enabling near real-time usage alignment and automated demand response.

✅ Twice-hourly reads miss 15-minute ERCOT price spikes.

✅ Less than 1% of 7.3M meters use HAN real-time features.

✅ Limits hinder automation for HVAC, EV charging, and pool pumps.

 

Utilities made a promise several years ago when they built Smart Meter Texas that they’d come up with a way for consumers to monitor their electricity use in real time. But now they’re backing out of the deal with the approval of state regulators, leaving in the lurch retail power companies that are building their business model on the promise of real time pricing and denying consumers another option for managing their electricity costs.

Texas utilities collected higher rates to finance the building of a statewide smart meter network that would allow customers to track their electricity use and the quickly changing prices on wholesale power markets almost as they happened. Some retailers are building electricity plans around this promise, providing customers with in-home devices that would eventually track pricing minute-by-minute and allow them to automatically turn down or shut off air conditioners, pool pumps and energy sucking appliances when prices spiked on hot summer afternoons and turn them back on when they prices fell again.

The idea is to help save consumers money by allowing them to shift their electricity consumption to periods when power is cheaper, typically nights and weekends, even as utility revenue in a free-power era remains a debated topic.

“We’re throwing away a large part of (what) ratepayers paid for,” said John Werner, CEO of GridPlus Texas, one of the companies offering consumers a real-time pricing plan that is scheduled to begin testing next month. “They made the smart meters dumb meters.”

When Smart Meter Texas was launched a decade ago by a consortium of the state’s biggest utilities, it was considered an important part of deregulation. The competitive market for electricity held the promise that consumers would eventually have the technology to control their electricity use through a home area network and cut their power bills.

Regulators and legislators also were enticed by the possibility of making the electric system more efficient and relieving pressure on the power grid as consumers responded to high prices and cut consumption when temperatures soared, with ongoing discussions about Texas grid reliability informing policy choices.

One study found that smart meters coupled with smart real time consumption monitors could reduce electricity use between 3 percent and 5 percent, according to Call Me Power, a website sponsored by the European electricity price shopping service Selectra.

But utilities complained that the home area network devices were expensive to install and not used very often, and, with flat electricity demand weighing on growth, they questioned further investment. CenterPoint manager Esther Floyd Kent filed an affidavit with the commission in May that it costs the utility about $30,000 annually to support the network devices, plus maintenance.

Over a six-year period, CenterPoint paid $124,500, or about $20,000 a year, to maintain the system. As of April, there were only 4,067 network devices in CenterPoint’s service area, meaning the utility pays about $30.70 each year to maintain each device.

Centerpoint last year generated $9.6 billion in revenues and earned a $1.8 billion profit, according to its financial filings. CenterPoint officials did not respond to requests for comment.

Other utilities that are part of the Smart Meter consortium also complained to the Public Utility Commission that, up to now, the system hasn’t developed. All told, Texas has 7.3 million meters connected to Smart Meter Texas, but less than 1 percent are using the networking functions to track real-time prices and consumption, according to the testimony of Donny R. Helm, director of technology strategy and architecture for the state’s largest utility Oncor Electric Delivery Co. in Dallas.

The isssue was resolved recently through a settlement agreement that limits on-demand readings to twice an hour that Smart Meter Texas must provide customers. The price of power changes every 15 minutes, so a twice an hour reading may miss some price spikes.

The Public Utility Commission signed off on the deal, and so did several other groups including several retail electricity providers and the Office of Public Utility Counsel which represents residential customers and small businesses.

Michele Gregg, spokeswoman for the Public Utility Counsel, testified in December that the consumer advocate supported the change because widespread use of the networks never materialized. Catherine Webking, an Austin lawyer who represents the Texas Energy Association for Marketers, a group of retail electric providers, said she believes the deal was a reasonable resolution of providing the benefits of Smart Meter Texas while not incurring too much cost.

But Griddy, an electricity provider that offers customers the opportunity to pay wholesale power prices, which also issued a plea to customers during a price surge, said the state hasn’t given the smart-meter networks a chance and could miss out on its potential. Griddy was counting on the continued adoption of real time pricing as the next step for customers wanting to control their electricity costs.

Right now, Griddy sends out price alerts from the grid operator Electric Reliability Council of Texas so businesses like hotels can run washers and dryers when electricity prices are cheapest. But the company was counting on a smart-meter program that would allow customers to track wholesale prices and manage consumption themselves, making Griddy’s offerings attractive to more people.

Wholesale prices are generally cheaper than retail prices, but they can fluctuate widely, especially when the Texas power grid faces another crisis during extreme weather. Last year, wholesale prices averaged less than 3 cents per kilowatt hour, much lower than than retail rates that now are running above 11 cents, but they can spike at times of high demand to as much as $9 a kilowatt hour.

What customers want is to be able to use energy when it’s cheapest, said Greg Craig, Griddy’s CEO, and they want to do it automatically. They want to be able to program their thermostat so that if the price rises they can shut off their air conditioning and if the price falls, they can charge their electric-powered vehicle.

Griddy customers may still save money even without real time data, he said. But they won’t be able to see their usage in real time or see how much they’re spending.

“The big utilities have big investments in the existing way and going to real time and more transparency isn’t really in their best interest,” said Craig.

Iran eyes transmitting electricity to Europe as region’s power hub

Iran Electricity Grid Synchronization enables regional interconnection, cross-border transmission, and Caspian-Europe energy corridors, linking Iraq, Azerbaijan, Russia, and Qatar to West Asia and European markets with reliable, flexible power exchange.

 

Key Points

Iran's initiative to link West Asian and European power grids for trade, transit, reliability, and regional influence.

✅ Synchronizes grids with Iraq, Azerbaijan, Russia, and potential Qatar link

✅ Enables east-to-Europe electricity transit via Caspian energy corridors

✅ Backed by gas-fueled and combined-cycle generation capacity

 

Following a plan for becoming West Asia’s electricity hub, Iran has been taking serious steps for joining its electricity network with neighbors in the past few years.

The Iranian Energy Ministry has been negotiating with the neighboring countries including Iraq for the connection of their power networks with Iran, discussing Iran-Iraq energy cooperation as well as ties with Russia, Afghanistan, Azerbaijan, and Qatar to make them enable to import or transmit their electricity to new destination markets through Iran.

The synchronization of power grids with the neighboring countries, not only enhances Iran’s electricity exchanges with them, but it will also increase the political stance of the country in the region.

So far, Iran’s electricity network has been synchronized with Iraq, where Iran is supplying 40% of Iraq's power today, and back in September, the Energy Minister Reza Ardakanian announced that the electricity networks of Russia and Azerbaijan are the next in line for becoming linked with the Iranian grid in the coming months.

“Within the next few months, the study project of synchronization of the electricity networks of Iran, Azerbaijan, and Russia will be completed and then the executive operations will begin,” the minister said.

Meanwhile, Ardakanian and Qatari Minister of State for Energy Affairs Saad Sherida Al-Kaabi held an online meeting in late September to discuss joining the two countries' electricity networks via sea.

During the online meeting, Al-Kaabi said: "Electricity transfer between the two countries is possible and this proposal should be worked on.”

Now, taking a new step toward becoming the region’s power hub, Iran has suggested becoming a bridge between East and Europe for transmitting electricity.

In a virtual conference dubbed 1st Caspian Europe Forum hosted by Berlin on Thursday, the Iranian energy minister has expressed the country’s readiness for joining its electricity network with Europe.

"We are ready to connect Iran's electricity network, as the largest power generation power in West Asia, with the European countries and to provide the ground for the exchange of electricity with Europe," Ardakanian said addressing the online event.

Iran's energy infrastructure in the oil, gas, and electricity sectors can be used as good platforms for the transfer of energy from east to Europe, he noted.

In the event, which was aimed to study issues related to the development of economic cooperation, especially energy, between the countries of the Caspian Sea region, the official added that Iran, with its huge energy resources and having skilled manpower and advanced facilities in the field of energy, can pave the ground for the prosperity of international transport and energy corridors.

"In order to help promote communication between our landlocked neighbors with international markets, as Uzbekistan aims to export power to Afghanistan across the region, we have created a huge transit infrastructure in our country and have demonstrated in practice our commitment to regional development and peace and stability," Ardakanian said.

He pointed out that having a major percentage of proven oil and gas resources in the world, regional states need to strengthen relations in a bid to regulate production and export policies of these huge resources and potentially play a role in determining the price and supply of these resources worldwide.

“EU countries can join our regional cooperation in the framework of bilateral or multilateral mechanisms such as ECO,” he said.

Given the growing regional and global energy needs and the insufficient investment in the field, with parts of Central Asia facing severe electricity shortages today, as well as Europe's increasing needs, this area can become a sustainable area of cooperation, he noted.

Ardakanian also said that by investing in energy production in Iran, Europe can meet part of its future energy needs on a sustainable basis.

In Iraq, plans for nuclear power plants are being pursued to tackle chronic electricity shortages, reflecting parallel efforts to diversify generation.

Iran currently has electricity exchange with Armenia, Azerbaijan, Iraq, where grid rehabilitation deals have been finalized, Turkmenistan, and Afghanistan.

The country’s total electricity exports vary depending on the hot and cold seasons of the year, since during the hot season which is the peak consumption period, the country’s electricity exports decreases, however electrical communication with neighboring countries continues.

Enjoying abundant gas resources, which is the main fuel for the majority of the country’s power plants, Iran has the capacity to produce about 85,500 megawatts [85.5 gigawatts (GW)] of electricity.

Currently, combined cycle power plants account for the biggest share in the country’s total power generation capacity as Iran is turning thermal plants to combined cycle to save energy, followed by gas power plants.

Powering Towards Net Zero: The UK Grid's Transformation Challenge

UK Electricity Grid Investment underpins net zero, reinforcing transmission and distribution networks to integrate wind, solar, EV charging, and heat pumps, while Ofgem balances investor returns, debt risks, price controls, resilience, and consumer bills.

 

Key Points

Capital to reinforce grids for net zero, integrating wind, solar, EVs and heat pumps while balancing returns and bills.

✅ 170bn-210bn GBP by 2050 to reinforce cables, pylons, capacity.

✅ Ofgem to add investability metric while protecting consumers.

✅ Integrates wind, solar, EVs, heat pumps; manages grid resilience.

 

Prime Minister Sunak's recent upgrade to his home's electricity grid, designed to power his heated swimming pool, serves as a microcosm of a much larger challenge facing the UK: transforming the nation's entire electricity network for net zero emissions, amid Europe's electrification push across the continent.

This transition requires a monumental £170bn-£210bn investment by 2050, earmarked for reinforcing and expanding onshore cables and pylons that deliver electricity from power stations to homes and businesses. This overhaul is crucial to accommodate the planned switch from fossil fuels to clean energy sources - wind and solar farms - powering homes with electric cars, as EV demand on the grid rises, and heat pumps.

The UK government's Climate Change Committee warns of potentially doubled electricity demand by 2050, the target date for net zero, even though managing EV charging can ease local peaks. This translates to a significant financial burden for companies like National Grid, SSE, and Scottish Power who own the main transmission networks and some regional distribution networks.

Balancing investor needs for returns and ensuring affordable energy bills for consumers presents a delicate tightrope act for regulators like Ofgem. The National Audit Office criticized Ofgem in 2020 for allowing network owners excessive returns, prompting concerns about potential bill hikes, especially after lessons from 2021 reshaped market dynamics.

Think-tank Common Wealth reported that distribution networks paid out a staggering £3.6bn to their owners between 2017 and 2021, raising questions about the balance between profitability and affordability, amid UK EV affordability concerns among consumers.

However, Ofgem acknowledges the need for substantial investment to finance network upgrades, repairs, and the clean energy transition. To this end, they are considering incorporating an "investability" metric, recognizing how big battery rule changes can erode confidence elsewhere, in the next price controls for transmission networks, ensuring these entities remain attractive for equity fundraising without overburdening consumers.

This proposal, while welcomed by the industry, has drawn criticism from consumer advocacy groups like Citizens Advice, who fear it could contribute to unfairly high bills. With energy bills already hitting record highs, public trust in the net-zero transition hinges on ensuring affordability.

High debt levels and potential credit rating downgrades further complicate the picture, potentially impacting companies' ability to raise investment funds. Ofgem is exploring measures to address this, such as stricter debt structure reporting requirements for regional distribution companies.

Lawrence Slade, CEO of the Energy Networks Association, emphasizes the critical role of investment in achieving net zero. He highlights the need for "bold" policies and regulations that balance ambitious goals with investor confidence and ensure efficient resource allocation, drawing on B.C.'s power supply challenges as a cautionary example.

The challenge lies in striking a delicate balance between attracting investment, ensuring network resilience, and maintaining affordable energy bills. As Andy Manning from Citizens Advice warns, "Without public confidence, net zero won't be delivered."

The UK's journey to net zero hinges on navigating this complex landscape. By carefully calibrating regulations, fostering investor confidence, and prioritizing affordability, the country can ensure its electricity grid is not just robust enough to power heated swimming pools, but also a thriving green economy for all.

Climate change poses high credit risks for nuclear power plants: Moody's

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

 

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

 

 

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”
