Growing body of research finds wind health claims linked to power of suggestion by anti-wind groups.

A new clinical study out of Australia finds that so-called "wind turbine sickness" may actually be caused by the suggestion from anti-wind groups that turbines make people sick.' The study found that 63 percent of Australia's 49 wind farms had never been the subject of any health complaint from nearby residents. It also found 68 percent of the 120 complaints that have been made came from residents living near wind farms heavily targeted by the anti-wind farm lobby, and that ''the advent of anti-wind farm groups beginning to foment concerns about health from around 2009 was also strongly correlated with actual complaints being made."

Study lead Simon Chapman, professor of public health at Sydney University, has said the results suggest that health problems attributed to wind energy are a "communicated disease" – or a sickness spread by the suggestion that something is likely to make a person sick. This is caused by the "nocebo effect" – the opposite of the placebo effect – in which the belief something can cause an illness creates the perception of illness. Chapman found a much greater connection between negative attitudes toward wind turbines and reports of health effects than any "objective measures of actual exposure."

"We review all credible information on the subject of wind turbines and human health as it is made available and it is clear that the balance of scientific evidence shows that wind turbines do not have an impact on human health. These new studies are of interest because they may have relevance for Canada where the majority of operating wind farms have not been the subject of health complaints by residents but anti-wind individuals and organizations have been traveling across Ontario and across Canada suggesting that Canadians will become ill from wind turbines."

"In many cases these presentations are made long before a wind turbine has even been constructed", says Robert Hornung, president of the Canadian Wind Energy Association CanWEA. "We believe Canadians should base their decisions about energy on facts grounded in the best scientific evidence. The fact remains that wind energy is one of the safest forms of electricity generation for both humans and wildlife."

Similar conclusions have been drawn in other research papers released this month.

Crichton, Fiona Dodd, George Schmid, Gian Gamble, Greg Petrie, Keith J. "Can Expectations Produce Symptoms From Infrasound Associated With Wind Turbines?” Health Psychology, March 2013 states that "Results suggest psychological expectations could explain the link between wind turbine exposure and health complaints."

Michael Witthöft, G. James Rubin "Are media warnings about the adverse health effects of modern life self-fulfilling? An experimental study on idiopathic environmental intolerance attributed to electromagnetic fields IEI-EMF", Journal of Psychosomatic Research, March 2013 concludes that "Media reports about the adverse effects of supposedly hazardous substances can increase the likelihood of experiencing symptoms following sham exposure and developing an apparent sensitivity to it."

Next Offshore Wind in U.S. Can Compete With Gas, Developer Says

Offshore Wind Cost Competitiveness is rising as larger turbines boost megawatt output, cut LCOE, and trim maintenance and installation time, enabling projects in New England to rival natural gas pricing while scaling reliably.

 

Key Points

It describes how larger offshore turbines lower LCOE and O&M, making U.S. projects price competitive with natural gas.

✅ Larger turbines boost MW output and reduce LCOE.

✅ Lower O&M and faster installation cut lifecycle costs.

✅ Competes with gas in New England bids, per BNEF.

 

Massive offshore wind turbines keep getting bigger, as projects like the biggest UK offshore wind farm come online, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas.

The price “is going to be a real eye-opener,” said Bryan Martin, chairman of Deepwater Wind LLC, which won an auction in May to build a 400-megawatt wind farm southeast of Rhode Island.

Deepwater built the only U.S. offshore wind farm, a 30-megawatt project that was completed south of Block Island in 2016. The company’s bid was selected by Rhode Island the same day that Massachusetts picked Vineyard Wind to build an 800-megawatt wind farm in the same area, while international investors such as Japanese utilities in UK projects signal growing confidence.

Bigger turbines that make more electricity have cut the cost per megawatt by about half, a trend aided by higher-than-expected wind potential in many markets, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants.

“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”

The Massachusetts project could be about $100 to $120 a megawatt hour, according to a February estimate from Harries, though recent UK price spikes during low wind highlight volatility. The actual prices there and in Rhode Island weren’t disclosed.

For comparison, a new U.S. combine-cycle gas turbine ranges from $40 to $60 a megawatt-hour, and a new coal plant is $67 to $113, according to BNEF data.

 

A new power plant in land-constrained New England would probably be higher than that, and during winter peaks the region has seen record oil-fired generation in New England that underscores reliability concerns. More importantly, gas plants get a significant portion of their revenue from being able to guarantee that power is always available, something wind farms can’t do, said William Nelson, a New York-based analyst with BNEF. Looking only at the price at which offshore turbines can deliver electricity is a “narrow mindset,” he said.

Clean energy jobs energize Pennsylvania: Clean Energy Employment Report

Pennsylvania Clean Energy Employment surges, highlighting workforce growth in energy efficiency, solar, wind, grid and storage, and alternative transportation, supporting COVID-19 recovery, high-wage jobs, manufacturing, construction, and statewide economic resilience.

 

Key Points

Jobs across clean power, efficiency, grid, storage, and advanced transport fueling Pennsylvania's workforce growth.

✅ 8.7% job growth from 2017-2019, outpacing statewide average

✅ 97,000+ employed across efficiency, solar, wind, grid, and fuels

✅ 75% earn above median; strong full-time opportunities

 

The 2020 Pennsylvania Clean Energy Employment Report has been released, and Gov. Tom Wolf is energized by it.

This "comes at an opportune time, as government and industry leaders look to strengthen Pennsylvania's workforce and economy in response to the challenges of the COVID-19 pandemic," Wolf said Monday in a prepared statement. "This detailed analysis of data and trends in clean energy employment ... demonstrates the sector was a top job generator statewide, and shows which industries were hiring and looking for trained workers."

Foremost among the findings, released Monday, is that the clean energy sector was responsible for adding 7,794 jobs from 2017 through 2019. That is an 8.7% average job growth rate, well above the 1.9% overall average in the state, according to a news release from Wolf's office.

This report lists employment data in five industries: energy efficiency; clean energy generation; alternative transportation; clean grid and storage; and clean fuels, while some cleaner states still import dirty electricity in regional markets.

The energy efficiency industry was the biggest clean energy employer in the state last year, with more than 71,400 state residents working in construction, technology and manufacturing jobs related to energy-efficient systems.

Solar energy workers comprised the largest share of the clean energy generation workforce – 35.4%, or 5,173 individuals. Solar employment increased 8.3% from 2017 to 2019, while there was a slight decline nationwide amid clean energy job losses reported in May.

Wind energy firms employed 2,937, and policy moves such as Ontario's clean electricity regulations signal broader market shifts, with more than 21% of those roles in manufacturing.

Job losses, though, were recorded in nuclear generation (minus 4.5%) and coal generation (minus 8.6%) over the two-year period, as electricity deregulation remains a point of debate in the sector. This mirrors national declines in both categories.

Federal efforts to support coal community revitalization are channeling clean energy projects to hard-hit regions.

Natural gas electric generation capacity doubled across Pennsylvania over the past decade; even as residents could face winter electricity price increases according to recent reports, employment still grew 13.4% from 2017 through 2019. But increasing output from unconventional wells has outpaced demand, sparking reductions in siting and drilling for new wells.

The Clean Energy Employment Report was released along with – and as part of – the 2020 Pennsylvania Energy Employment Report, which asserts that energy remains a large employer in the state, and new clean energy funding announcements underscore the sector's momentum. As of the last quarter of 2019, according to the larger report, energy accounted for 269,031 jobs, or 4.5% of the overall statewide workforce.

Wolf, in summary, said: "This report shows that workforce training investment decisions can benefit Pennsylvanians right now and position the state going forward to grow and improve livelihoods, the economy and our environment."

Canadian Solar and Tesla contribute to resilient electricity system for Puerto Rico school

SunCrate Solar Microgrid delivers resilient, plug-and-play renewable power to Puerto Rico schools, combining Canadian Solar PV, Tesla Powerwall battery storage, and Black & Veatch engineering to ensure off-grid continuity during outages and disasters.

 

Key Points

A compact PV-and-battery system for resilient, diesel-free power and microgrid backup at schools and clinics.

✅ Plug-and-play, modular PV, inverter, and battery architecture

✅ Tesla Powerwall storage; Canadian Solar 325 W panels

✅ Scales via daisy-chain for higher loads and microgrids

 

Eleven months since their three-building school was first plunged into darkness by Hurricane Maria, 140 students in Puerto Rico’s picturesque Yabucoa district have reliable power. Resilient electricity service was provided Saturday to the SU Manuel Ortiz school through an innovative scalable, plug-and-play solar system pioneered by SunCrate Energy with Black & Veatch support. Known as a “SunCrate,” the unit is an effective mitigation measure to back up the traditional power supply from the grid. The SunCrate can also provide sustainable power in the face of ongoing system outages and future natural disasters without requiring diesel fuel.

The humanitarian effort to return sustainable electricity to the K-8 school, found along the island’s hard-hit southeastern coast, drew donated equipment and expertise from a collection of North American companies. Additional support for the Yabucoa project came from Tesla, Canadian Solar and Lloyd Electric, reflecting broader efforts to build a solar-powered grid in Puerto Rico after Hurricane Maria.

“We are grateful for this initiative, which will equip this school with the technology needed to become a resilient campus and not dependent on the status of the power grid. This means that if we are hit with future harmful weather events, the school will be able to open more quickly and continue providing services to students,” Puerto Rico Secretary of Education Julia Keleher said.

The SunCrate harnesses a scalable rapid-response design developed by Black & Veatch and manufactured by SunCrate Energy. Electricity will be generated by an array of 325-W CS6U-Poly modules from Canadian Solar. California-based Tesla contributed advanced battery energy storage through various Powerwall units capable of storing excess solar power and delivering it outside peak generation periods, with related experience from a virtual power plant in Texas informing deployment.  Lloyd Electric Co. of Wichita Falls, Texas, partnered to support delivery and installation of the SunCrate.

“As families in the region begin to prepare for the school year, this community is still impacted by the longest U.S. power outage in history,” said Dolf Ivener, a Midwestern entrepreneur who owns King of Trails Construction and SunCrate Energy, which is donating the SunCrate. “SunCrate, with its rapid deployment and use of renewable energy, should give this school peace of mind and hopefully returns a touch of long-overdue normalcy to students and their parents. When it comes to consistent power, SunCrate is on duty.”

The SunCrate is a portable renewable energy system conceived by Ivener and designed and tested by Black & Veatch. Its modular design uses solar PV panels, inverters and batteries to store and provide electric power in support of critical services such as police, fire, schools, clinics and other community level facilities.

A SunCrate can generate 23 to 156 kWh per day, and store 10 kWh to 135 kWh depending on configuration. A SunCrate’s power generation and storage capacity can be easily scaled through daisy-chained configurations to accommodate larger buildings and loads. Leveraging resources from Tesla, Canadian Solar, Lloyd Electric and Lord Electric, the unit in Yabucoa will provide an estimated 52 kWh of storable power without requiring use of costlier diesel-powered generators and cutting greenhouse gas emissions. Its capabilities allow the school to strengthen its function as a designated Community Emergency Response Center in the event of future natural disasters.

“Canadian Solar has a long history of using solar power to support humanitarian efforts aiding victims of social injustice and natural disasters, including previous donations to Puerto Rico after Hurricane Maria,” said Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar. “We are pleased to make the difference for these schoolchildren in Yabucoa who have been without reliable power for too long.”

The SunCrate will also substantially lower the school’s ongoing electricity costs by providing a reliable source of renewable energy on site, as falling costs of solar batteries improve project economics overall.

“Through our experience providing engineering services in Puerto Rico for nearly 50 years, including dozens of specialized projects for local government and industrial clients, we see great potential for SunCrate as a source of resilient power for the Commonwealth’s remote schools and communities at large, underscoring the importance of electricity resilience across critical infrastructure,” said Charles Moseley, a Program Director in Black & Veatch’s water business. “We hope that the deployment of the SunCrate in Yabucoa sets a precedent for facility and municipal level migro-grid efforts on the island and beyond.”

SunCrate also has broad potential applications in conflict/post-conflict environments and in rural electrification efforts in the developing world, serving as a resilient source of electricity within hours of its arrival on site and could enable peer-to-peer energy within communities. Of particular benefit, the system’s flexibility cuts fuel costs to a fraction of a generator’s typical consumption when they are used around the clock with maintenance requirements.

Judge: Texas Power Plants Exempt from Providing Electricity in Emergencies

Texas Blackout Liability Ruling clarifies appellate court findings in Houston, citing deregulated energy markets, ERCOT immunity, wholesale generators, retail providers, and 2021 winter storm lawsuits over grid failures and wrongful deaths.

 

Key Points

Houston judges held wholesale generators owe no duty to retail customers, limiting liability for 2021 blackout lawsuits.

✅ Court cites deregulated market and lack of privity to consumers

✅ Ruling shields generators from 2021 winter storm civil suits

✅ Plaintiffs plan appeals; legislature may address liability

 

Nearly three years after the devastating Texas blackout of 2021, a panel of judges from the First Court of Appeals in Houston has determined that major power companies cannot be held accountable for their failure to deliver electricity during the power grid crisis that unfolded, citing Texas' deregulated energy market as the reason.

This ruling appears likely to shield these companies from lawsuits that were filed against them in the aftermath of the blackout, leaving the families of those affected uncertain about where to seek justice.

In February 2021, a severe cold front swept over Texas, bringing extended periods of ice and snow. The extreme weather conditions increased energy demand while simultaneously reducing supply by causing power generators and the state's natural gas supply chain to freeze. This led to a blackout that left millions of Texans without power and water for nearly a week.

The state officially reported that almost 250 people lost their lives during the winter storm and subsequent blackout, although some analysts argue that this is a significant undercount and warn of blackout risks across the U.S. during severe heat as well.

In the wake of the storm, Texans affected by the energy system's failure began filing lawsuits, and lawmakers proposed a market bailout as political debate intensified. Some of these legal actions were directed against power generators whose plants either ceased to function during the storm or ran out of fuel for electricity generation.

After several years of legal proceedings, a three-judge panel was convened to evaluate the merits of these lawsuits.

This week, Chief Justice Terry Adams issued a unanimous opinion on behalf of the panel, stating, "Texas does not currently recognize a legal duty owed by wholesale power generators to retail customers to provide continuous electricity to the electric grid, and ultimately to the retail customers."

The opinion further clarified that major power generators "are now statutorily precluded by the legislature from having any direct relationship with retail customers of electricity."

This separation of power generation from transmission and retail electric sales in many parts of Texas resulted from energy market deregulation in the early 2000s, with the goal of reducing energy costs, and prompted electricity market reforms aimed at avoiding future blackouts.

Under the previous system, power companies were "vertically integrated," controlling generators, transmission lines, and selling the energy they produced directly to regional customers. However, in deregulated areas of Texas, competition was introduced, creating competing energy-generating companies and retail electric providers that purchase power wholesale and then sell it to residential consumers; meanwhile, electric cooperatives in other parts of the state remained member-owned providers.

Tré Fischer, a partner at the Jackson Walker law firm representing the power companies, explained, "One consequence of that was, because of the unbundling and the separation, you also don't have the same duties and obligations [to consumers]. The structure just doesn't allow for that direct relationship and correspondingly a direct obligation to continually supply the electricity even if there's a natural disaster or catastrophic event."

In the opinion, Justice Adams noted that when designing the Texas energy market, amid renewed interest in ways to improve electricity reliability across the grid, state lawmakers "could have codified the retail customers' asserted duty of continuous electricity on the part of wholesale power generators into law."

The recent ruling applies to five representative cases chosen by the panel out of hundreds filed after the blackout. Due to this decision, it is improbable that any of the lawsuits against power companies will succeed, according to the court's interpretation.

However, plaintiffs' attorneys have indicated their intention to appeal. They may request a review of the panel's opinion by the entire First Court of Appeals or appeal directly to the state supreme court.

The state Supreme Court had previously ruled that the Electric Reliability Council of Texas (ERCOT), the state's power grid operator, enjoys sovereign immunity and cannot be sued over the blackout.

This latest opinion raises the question of who, if anyone, can be held responsible for deaths and losses resulting from the blackout, a question left unaddressed by the court. Fischer commented, "If anything [the judges] were saying that is a question for the Texas legislature."

Alberta Leads the Way in Agrivoltaics

Agrivoltaics in Alberta integrates solar energy with agriculture, boosting crop yields and water conservation. The Strathmore Solar project showcases dual land use, sheep grazing for vegetation control, and PPAs that expand renewable energy capacity.

 

Key Points

A dual-use model where solar arrays and farming co-exist, boosting yields, saving water, and diversifying revenue.

✅ Strathmore Solar: 41 MW on 320 acres with managed sheep grazing

✅ 25-year TELUS PPA secures power and renewable energy credits

✅ Panel shade cuts irrigation needs and protects crops from extremes

 

Alberta is emerging as a leader in agrivoltaics—the innovative practice of integrating solar energy production with agricultural activities, aligning with the province's red-hot solar growth in recent years. This approach not only generates renewable energy but also enhances crop yields, conserves water, and supports sustainable farming practices. A notable example of this synergy is the Strathmore Solar project, a 41-megawatt solar farm located on 320 acres of leased industrial land owned by the Town of Strathmore. Operational since March 2022, it exemplifies how solar energy and agriculture can coexist and thrive together.

The Strathmore Solar Initiative

Strathmore Solar is a collaborative venture between Capital Power and the Town of Strathmore, with a 25-year power purchase agreement in place with TELUS Corporation for all the energy and renewable energy credits generated by the facility. The project not only contributes significantly to Alberta's renewable energy capacity, as seen with new solar facilities contracted at lower cost across the province, but also serves as a model for agrivoltaic integration. In a unique partnership, 400 to 600 sheep from Whispering Cedars Ranch are brought in to graze the land beneath the solar panels. This arrangement helps manage vegetation, reduce fire hazards, and maintain the facility's upkeep, all while providing shade for the grazing animals. This mutually beneficial setup maximizes land use efficiency and supports local farming operations, illustrating how renewable power developers can strengthen outcomes with integrated designs today. 

Benefits of Agrivoltaics in Alberta

The integration of solar panels with agricultural practices offers several advantages for a province that is a powerhouse for both green energy and fossil fuels already across sectors:

  • Enhanced Crop Yields: Studies have shown that crops grown under solar panels can experience increased yields due to reduced water evaporation and protection from extreme weather conditions.

  • Water Conservation: The shade provided by solar panels helps retain soil moisture, leading to a decrease in irrigation needs.

  • Diversified Income Streams: Farmers can generate additional revenue by selling renewable energy produced by the solar panels back to the grid.

  • Sustainable Land Use: Agrivoltaics allows for dual land use, enabling the production of both food and energy without the need for additional land.

These benefits are evident in various agrivoltaic projects across Alberta, where farmers are successfully combining crop cultivation with solar energy production amid a renewable energy surge that is creating thousands of jobs.

Challenges and Considerations

While agrivoltaics presents numerous benefits, there are challenges to consider as Alberta navigates challenges with solar expansion today across Alberta:

  • Initial Investment: The setup costs for agrivoltaic systems can be high, requiring significant capital investment.

  • System Maintenance: Regular maintenance is essential to ensure the efficiency of both the solar panels and the agricultural operations.

  • Climate Adaptability: Not all crops may thrive under the conditions created by solar panels, necessitating careful selection of suitable crops.

Addressing these challenges requires careful planning, research, and collaboration between farmers, researchers, and energy providers.

Future Prospects

The success of projects like Strathmore Solar and other agrivoltaic initiatives in Alberta indicates a promising future for this dual-use approach. As technology advances and research continues, agrivoltaics could play a pivotal role in enhancing food security, promoting sustainable farming practices, and contributing to Alberta's renewable energy goals. Ongoing projects and partnerships aim to refine agrivoltaic systems, making them more efficient and accessible to farmers across the province.

The integration of solar energy production with agriculture in Alberta is not just a trend but a transformative approach to sustainable farming. The Strathmore Solar project serves as a testament to the potential of agrivoltaics, demonstrating how innovation can lead to mutually beneficial outcomes for both the agricultural and energy sectors.

Spent fuel removal at Fukushima nuclear plant delayed up to 5 years

Fukushima Daiichi decommissioning delay highlights TEPCO's revised timeline, spent fuel removal at Units 1 and 2, safety enclosures, decontamination, fuel debris extraction by robot arm, and contaminated water management under stricter radiation control.

 

Key Points

A government revised schedule pushing back spent fuel removal and decommissioning milestones at Fukushima Daiichi.

✅ TEPCO delays spent fuel removal at Units 1 and 2 for safety.

✅ Enclosures, decontamination, and robotics mitigate radioactive risk.

✅ Contaminated water cut target: 170 tons/day to 100 by 2025.

 

The Japanese government decided Friday to delay the removal of spent fuel from the Fukushima Daiichi nuclear power plant's Nos. 1 and 2 reactors by as much as five years, casting doubt on whether it can stick to its timeframe for dismantling the crippled complex.

The process of removing the spent fuel from the units' pools had previously been scheduled to begin in the year through March 2024.

In its latest decommissioning plan, the government said the plant's operator, Tokyo Electric Power Company Holdings Inc., will not begin the roughly two-year process (a timeline comparable to major reactor refurbishment programs seen worldwide) at the No. 1 unit at least until the year through March 2028 and may wait until the year through March 2029.

Work at the No. 2 unit is now slated to start between the year through March 2025 and the year through March 2027, it said.

The delay is necessary to take further safety precautions such as the construction of an enclosure around the No. 1 unit to prevent the spread of radioactive dust, and decontamination of the No. 2 unit, even as authorities have begun reopening previously off-limits towns nearby, the government said. It is the fourth time it has revised its schedule for removing the spent fuel rods.

"It's a very difficult process and it's hard to know what to expect. The most important thing is the safety of the workers and the surrounding area," industry minister Hiroshi Kajiyama told a press conference.

The government set a new goal of finishing the removal of the 4,741 spent fuel rods across all six of the plant's reactors by the year through March 2032, amid ongoing debates about the consequences of early nuclear plant closures elsewhere.

Plant operator TEPCO has started the process at the No. 3 unit and already finished at the No. 4 unit, which was off-line for regular maintenance at the time of the disaster. A schedule has yet to be set for the Nos. 5 and 6 reactors.

While the government maintained its overarching timeframe of finishing the decommissioning of the plant 30 to 40 years from the 2011 crisis triggered by a magnitude 9.0 earthquake and tsunami, there may be further delays, even as milestones at other nuclear projects are being reached worldwide.

The government said it will begin removing fuel debris from the three reactors that experienced core meltdowns in the year through March 2022, starting with the No. 2 unit as part of broader reactor decommissioning efforts.

The process, considered the most difficult part of the decommissioning plan, will involve using a robot arm, reflecting progress in advanced reactors technologies, to initially remove small amounts of debris, moving up to larger amounts.

The government also said it will aim to reduce the pace at which contaminated water at the plant increases. Water for cooling the melted cores, mixed with underground water, amounts to around 170 tons a day. That number will be brought down to 100 tons by 2025, it said.

The water is being treated to remove the most radioactive materials and stored in tanks on the plant's grounds, but already more than 1 million tons has been collected and space is expected to run out by the summer of 2022.
