Double harvest: #raspberries and #RenewableEnergy - #FruitLogistica
Excerpts: "Based on current findings, strawberries do not thrive under #SolarPanels, so this combination of crops does not have a promising future. This was the conclusion of a Wageningen University study on fruit cultivation beneath #photovoltaic systems.
Strawberries grown beneath solar panels with 25 to 50 per cent light transmission experienced a significant drop in yield – by 25 to 30 per cent.
The situation was quite different for raspberries, however: under solar panels with 40 per cent light transmission, the harvest yield fell by only five per cent, and the quality of the fruit remained unchanged. At the same time, the panels reduced evaporation and water consumption, protecting the berries from burns and heat peaks.
The scientists also expect positive effects on #WaterConsumption and protection against #ExtremeWeather conditions.
[...]
One clear advantage is that raspberries are currently grown under rain protection films that have to be replaced every five to seven years. This equates to a significant amount of plastic that would no longer be required if solar modules were used instead. And they last at least ten years."

From 2013: Ten Most #Radioactive Places on Earth Mapped Out [GRAPHIC]
"Do you know the dirty side of the #NuclearIndustry? After researching this article by brainz.org, we were shocked to find out how truly awful our radioactive waste problem is and how it is going to be hurting us all, for a long time to come. Please take the time to read the links below, share this with your friends, and discuss solutions to these problems. ~ Jim Lee, #ClimateViewer News
"This list is not a definitive TOP TEN, it is simply ten very disgusting examples of nuclear warfare against the citizens of this world."

World’s biggest #NuclearPlant fires up 1,356MW reactor after 13-year freeze
Story by Everett Sloane, February 11, 2026
Excerpt: "Coverage of the planned restart has noted that Japan’s #Kashiwazaki and Kariwa units faced a suspension just hours after an earlier attempt began, after a minor malfunction triggered alarms. Separate reporting on Jan developments stressed that the significance of bringing Reactor No. 6 online was rising as tight supply threatened winter reliability, a reminder that grid operators are juggling risk on two fronts at once: the risk of another accident and the risk of blackouts if demand outstrips capacity. This dual pressure is why I see unit 6 less as a side story and more as the template regulators will use to judge whether No. 7 can safely move from fuel loading to full power."

Essay - How the climate conversation went punk
From #SlowFashion to #GuerrillaGardening, the internet has transformed solarpunk, a literary movement, into an alternative lifestyle trend.
Written by Sonal Gupta
Mumbai | Updated: November 20, 2025Excerpt: "In 2020, #SolarPunkFarms cropped up in California as a #communal living space whose inhabitants grow and share their own food. The leftovers are sent to local markets. They have designed their #greenhouse after the animations of #HayaoMiyazaki. In fact, the works of the #StudioGhibli founder have found resonance among solarpunks, as he places nature as a character in his plots. In his visions, nature is at its most beautiful—lush greenery, rays of light, the dew on leaves, and the wind blowing life into trees.
"Though these changes are encouraging, it’s ironic that as we move past dystopian visions, the #capitalists of the world, running in the #AI race, threaten to steer us to the very future. The use of AI itself depletes water resources and generates immense amounts of greenhouse gases and electronic waste. If we are to live in a world where technology exists in harmony with #nature, #activists, stakeholders, and individuals must actively call for more #SustainableSolutions, #AffirmativeAction, and policy changes.
"If cyberpunk warned us of what happens when technology consumes humanity, solarpunk invites us to imagine what is possible when humanity reclaims technology. It reminds us that hope, like sunlight, is a renewable resource too."

We’re having a #heatwave...
And #NuclearPower can’t cope. Worse still, it’s actually a liability under ever more extreme climate conditions, write Karl Grossman and Harvey Wasserman
Posted on July 27, 2025, by #BeyondNuclear
"At the core of the latest attempted 'renaissance' of nuclear power is the big lie that #AtomicReactors are an answer to #GlobalWarming. In fact, they are significant sources of heat.
"There are more than 400 nuclear power plants in the world today that fission atoms at 300 degrees Centigrade, (572 degrees Fahrenheit). More are under construction or proposed. As the International Atomic Energy Agency states, 'water-cooled reactors offer heat up to 300 degrees Celsius. These types of reactors include pressurized water reactors (PWRs), boiling-water reactors (BWRs), pressurized heavy-water reactors, and light-water-cooled graphite-moderated reactors (LWGRs).'
"Some heat is absorbed in the water—drawn from water bodies—used to cool these nuclear power plants and then returned, still with considerable heat, to #rivers or #seas.
"The heatwave going on in recent weeks in Europe, in combination with this discharge of heated water from nuclear plants, has caused #NuclearPlants there to shut down.
"Consider these headlines from recent days:
" '#France and #Switzerland shut down nuclear power plants amid scorching heatwave,' was the July 3rd headline on Euronews. As the piece explained: “To cool down, nuclear power plants pump water from local rivers or the sea, which they then release back into water bodies at a high temperature. However, Europe’s ongoing heatwave means that the water pumped by nuclear sites is already very hot, impacting the ability of nuclear plants to use it to cool down. On top of this, nuclear sites run the risk of posing a dangerous threat to local #biodiversity, by releasing water which is too hot into rivers and seas.'
"A New York Times article, also dated July 3rd, related how in Europe, 'operators shut down one of the two reactors at the #Golfech nuclear power plant in southern #France after forecasts that the #GaronneRiver, from which it draws water and then discharges it after it is used in the plant as coolant, 'could top…82 degrees Fahrenheit.' The Times continued: 'The #Beznau Nuclear Power Plant in #Switzerland, built along the #AareRiver followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.' "

Risky Revival: How #Michigan’s #Palisades #NuclearPlant could impact agriculture
While state leaders champion the Palisades reopening as an energy solution, local farmers remain divided over the potential threats to their land and water.
by S. Nicole Lane, for Investigate Midwest December 10, 2024COVERT, Michigan — "The Palisades Nuclear Generating Station, long synonymous with safety lapses and regulatory oversight, is poised for an unprecedented comeback under Michigan Gov. #GretchenWhitmer’s plan to reopen the shuttered plant by 2025 — the first attempt of its kind in U.S. history.
"However, in this robust agricultural region, there are fears about how reopening a problematic plant could impact area farmers and the food they produce.
"Approximately 6,362 farms are within 50 miles of Palisades. In Van Buren County alone, where the plant is located, there are 838 farms. Michigan’s southwestern corner, home to 80% of the state’s farms, is often called the 'blueberry capital of the world.'
"'A leak (and) this 150-year-old farm is done,' said Bill Adams, who runs Adams Blueberry Farms in Hartford, Michigan, 16 miles south of the plant. 'Why would they restart something that old and sitting this long?'
"Opened in 1971, Palisades, which is located along #LakeMichigan, once generated 5% of Michigan’s electricity, enough to power 800,000 homes. But a litany of mechanical issues plagued its operations for decades.
"In 2013, the plant leaked 79 gallons of diluted #RadioactiveWater into Lake Michigan, forcing a five-week shutdown — its ninth closure in just two years.
"Federal regulators repeatedly flagged the plant for safety concerns, from undetected #RadiationExposure among employees in 2008 to persistent cracks in its 300,000-gallon storage tank that leaked for over a decade. In 2012, the Nuclear Regulatory Commission (NRC) described Palisades as having some of the worst cases of nuclear fuel container weakening in the nation.
"The plant was permanently shut down on May 31, 2022, with its owners citing financial and safety concerns. But just months later, Whitmer announced a plan to revive Palisades, reigniting debates over the risks and benefits of #NuclearEnergy in a state still grappling with its troubled legacy.
"Typically, after 40 years, a nuclear power plant is closed and undergoes a complex decommissioning process that can take up to 30 years to complete. Globally, the only plants that have reopened are in Japan.
"#Holtec Decommissioning International bought Palisades in 2022 with the goal of dismantling it. Now, with Whitmer’s support, they have since decided to reopen the plant, something Holtec has never done.
"Neither Holtec nor Whitmer’s office responded to multiple requests for comment. "

From the Bretton Woods Project: #Forests
"Finally, the [#WorldBank] ’s #forest policy and #WeakSafeguards on #ForestProtection have also been observed to infringe the rights of local communities and have failed to protect one of the planet’s most important ‘#CarbonSinks’ (see Observer Spring 2017). CSOs have called for the Bank to open up its Forest Notes – which are meant to guide the interface between its lending and forests – to consultation (see Observer Winter 2017-2018). CSOs have also been highly critical of one of the forest initiatives the Bank manages, the Forest Carbon Partnership Facility (FCPF), a climate investment fund that supports Reducing Emissions from Deforestation and Forest Degradation (REDD) projects. A March 2017 post in REDD Monitor called the FCPF, 'the most cost-inefficient tree-saving scheme ever,' owing to high administrative costs between fiscal years 2009-2015 absorbing 64 per cent of FCFP’s $55 million expenditure. More generally, the Bank’s overall approach to lending has undermined the protection of vital natural ecosystems in borrower countries. As noted by Bruce Rich in his influential 2013 book, Foreclosing the Future: The World Bank and the Politics of Environmental Destruction, 'When one examines the failures to conserve ecosystems, or to mitigate environmental impacts of development, one finds that failed governance at all levels is almost invariably at the root. …Many of [the Bank’s] problems are associated with a dysfunctional institutional culture in which the relentless pressure to move money out the door, even in violation of the Bank’s own policies and rules, often overrides all other considerations.'"
2017: World Bank policy lending undermines climate goals
"One of the main problems is the Bank’s refusal to adequately assess the social and environmental risks of their policy loans" - Harlem Mariño, Derechos, Ambiente y Recursos Naturales
6 April 2017
"A late January report by US-based NGO Bank Information Center (BIC), together with partners in Egypt, Indonesia, Mozambique and Peru, claimed that the Bank is undermining its climate commitments by supporting investment incentives for coal, gas and oil projects through its development policy financing (DPF) mechanism. DPF accounts for approximately a third of all Bank funding and provides resources for programmes of policy and institutional reforms that are agreed by the Bank and the borrowing government (see Update 82). The report argued that the Bank’s financing through DPF contradicts the internationally agreed and Bank-supported goal of limiting the global average temperature increase to 2°C, which according to the Intergovernmental Panel on Climate Change would require that at least two-thirds of existing fossil fuel reserves are left in the ground.
"BIC’s report looked at the Bank’s DPF measures in four countries: Egypt, Indonesia, Mozambique and Peru. It found that DPF introduced subsidies for coal in all countries, apart from Peru. For example, the report argued that Bank-supported subsidies for coal infrastructure have helped Indonesia become one of the world’s top coal exporters. It found some DPF support for renewable energy, but argued that the Bank could do more given that all countries examined have potential to develop renewable energy. For example, while Peru’s DPF provides subsidies to public-private partnerships to develop oil and gas infrastructure, it does not include plans for solar or wind power projects."

#Diné Youth at #WorldWaterWeek in Sweden 2024
#BlackMesa youth travel to Stockholm, Sweden, for World Water Week to share the need to protect our water in the face of #FalseSolutions and #ClimateChange.
by Adrian Herder, Media/Community Organizer, #CensoredNews
[email protected]FLAGSTAFF, Arizona – "On Friday, August 23, 2024, members of #TóNizhóníÁní traveled to Stockholm, Sweden, for World Water Week 2024, an international leading conference on global water issues organized by the Stockholm International Water Institute. Earlier this year, Tó Nizhóní Ání was invited to attend World Water Week 2024 and asked to be on a panel on #GreenColonialism. The #Sámi national youth organization, #Sáminuorra, organized this panel. Given this panel's #Indigenous youth focus, Tó Nizhóní Ání took this opportunity to fund raise and send a delegation of Diné (#Navajo) youth from the Black Mesa region to represent and speak on this topic.
"During the panel on Green Colonialism, #JarenNumkena, Diné youth from Black Mesa, spoke on his upbringing as a farmer, the history of his family as a #coal-impacted community member, and the proposed projects on and near Black Mesa, such as the #BlackMesaPumpedStorageProject and the #HydrogenPipeline. As our nation moves to alternative forms of energy, we must do so in a way that does not use or impact our water on the #NavajoNation, which is why we need #solar and #wind energy."

#DiabloCanyon #NuclearPowerPlant brings #profits for PG&E, deadly risk for residents [and the #environment]
Tina Landis
August 19, 2024"Despite opposition from residents and #environmental organizations, California legislators passed #SenateBill846 in 2022 to extend the life of the dangerous, aging Diablo Canyon #nuclear facility.
"Located on the Central Coast surrounded by several #fault lines, one has to question why a nuclear facility was placed in an #earthquake zone to begin with, much less allowing it to continue to operate well past its retirement date. The world witnessed what can happen to a coastal nuclear facility in an earthquake zone when the 2011 #Fukushima disaster triggered a meltdown that displaced nearly half a million residents, with vast amounts of #RadioactiveWater still being released into the ocean today.
"As long as Diablo Canyon remains open, Californians live with the constant risk of suffering the same type of disaster.
"From its inception, Diablo Canyon had little public support. Protests occurred regularly during its construction, and thousands were arrested for #CivilDisobedience actions in 1981.
"In the 1970s and 1980s, California’s three largest utilities spent billions of dollars building dangerous and costly nuclear plants like Diablo Canyon, which resulted in skyrocketing rates for customers. Big industry fought back against these increased energy costs, which resulted in deregulation bills consisting of multi-billion dollar #bailouts to the state’s utility companies to cover their costly investments in nuclear.
"Today, the last remaining nuclear plant operating in the state is still draining billions in funds that could be used for safe, #renewable energy development. To keep Diablo Canyon running 5 years past its retirement date is expected to cost $8 billion to $12 billion. A federal aid package of $1.1 billion will contribute to some of those costs – meaning federal #taxpayers’ money – while the remaining billions will be passed on to #California #ratepayers.
"Despite being run by PG&E and only generating power for its territory, customers of #SouthernCaliforniaEdison and #SanDiegoGasAndElectric will help cover the remaining costs of the Diablo extension. Edison bills will increase by around $1.25 a month and SDG&E by 87 cents a month, while PG&E customers are expected to chip in $2.07 a month – and that’s just for the first year. Critics warn that costs are likely to increase in coming years to keep the plant running, and that’s on top of already skyrocketing PG&E rates that have doubled over the last decade. And if PG&E collects more funds than are needed for Diablo’s operations, they get to keep it!
"In 2022, when legislators pushed this through #SB846, the excuse of energy shortages was used due to pandemic-related supply chain issues and massive #wildfires. But today, there is plenty of energy being produced with increased #solar and #battery storage capacity that has kept the lights on even during this summer’s unprecedented heat waves driving up demand. The California Public Utility Commission’s own reporting shows that an additional 18,500 megawatts of new resources were added to the grid between 2020 and 2024, which is enough to power around 14 million homes. Another 11,000 megawatts will be added by 2028.
"Nuclear has the third highest lifecycle emissions of all energy sources after scrubbed #coal fired plants and natural gas – meaning it is far from being zero-emission. It also creates the unresolved issue of the #RadioactiveWaste which remains dangerous for tens of thousands to millions of years.
"Keeping the Diablo facility running will only hold back further development of safe and truly low-carbon, low cost renewable sources like solar and #wind energy.
"So why isn’t Diablo Canyon being decommissioned? The short answer is that #capitalism must ensure continued profits for the #InvestorClass.
"SB 846 authorized Diablo’s extension through 2030, and gave PG&E a $1.4 billion loan for the for-profit utility to facilitate the plant’s extension. #GovernorNewsom facilitated another transfer of taxpayer dollars to PG&E through an additional $400 million loan from the state’s general fund, included in the recent budget deal. Critics warn that these 'loans' will never be repaid, meaning residents will be fully subsidizing the Diablo extension – from federal and state tax dollars to our utility fees.
"But there is a way out. SB 846 allows the #CPUC to retire the plant earlier than 2030 if sufficient levels of new renewable zero-carbon energy resources exist, are interconnected, and meet demand, which is the case.
"CPUC has a long track record of serving PG&E’s interests, so intervention by the commission is unlikely. One example of many that demonstrates their close relationship: CPUC is not requiring PG&E to show how much of our utility bill actually goes to the Diablo extension, but instead lumps the cost in with 'public purpose programs,' making it impossible to determine.
"While communities are demanding an early shutdown of Diablo, PG&E is currently applying for a 20-year license renewal from the Nuclear Regulatory Commission [#NRC] for the facility, which is expected to be approved. This would mean customers will foot the bill to keep this dangerous nuclear facility running through 2045, far beyond the original expiration dates of 2024 and 2025.
"CPUC has proven their unwavering support time and again for PG&E’s monopoly control over the state’s energy system at the expense of residents’ safety and affordable rates. The Diablo Canyon nuclear plant is just another mechanism to squeeze ratepayers and line the pockets of shareholders who live far away from the dangers posed by this aging facility. Only a public takeover of this #corrupt utility can win clean, safe and affordable energy for all."

North Texans want more say as nuclear plant seeks to continue operating through 2053
By Haley Samsel
December 11, 2023"Crossing the dark parking lot outside the Somervell County Expo Center, Susybelle Gosslee barely could see the ground in front of her. The experience left her feeling 'vulnerable' — and concerned about why the Nuclear Regulatory Commission [#NRC] didn’t turn on outdoor lights for its Dec. 7 public meeting about the #ComanchePeak #nuclear power plant in #GlenRoseTexas.
"That wasn’t her only critique. Earlier in the day, Gosslee and other #environmental advocates struggled to log on to a virtual meeting hosted by the commission. Officials apologized for the challenges and vowed to host another online session the week of Dec. 18.
"'That is not transparency, and it’s not good government,' Gosslee, the Dallas-based chair of #HazardousWaste issues for the League of Women Voters of Texas, said. 'I’m concerned because of the lack of access to meetings, and you can see that it wasn’t well-publicized because there is nobody here. That’s an indicator that the job did not get done.'
"Gosslee’s criticism comes as #Vistra, the owner of the Comanche Peak nuclear power plant in Glen Rose, seeks to keep its reactors online through at least 2053. The plant began operation in 1990.
"The company’s current licenses for two nuclear units, which have the capacity to power 1.2 million homes under normal electricity conditions, expire in 2030 and 2033. Vistra announced its license renewal application in October 2022, citing a desire to bring more 'carbon-free electricity' to the electric grid.
"'Renewing the licenses of this plant is critical for grid reliability and our environment and is a benefit to the economy, the local community and our company,' Jim Burke, president and CEO of Vistra, said at the time.
As part of the license renewal process, the Nuclear Regulatory Commission has already heard from dozens of residents living in the plant’s 50-mile radius, including parts of Tarrant, Hood and Somervell counties.
"Many are supportive of Comanche Peak’s continued operation, citing its economic contributions as Somervell County’s largest taxpayer and an employer of more than 600 full-time staff. At a January public meeting, Glen Rose ISD Superintendent Trig Overbo and Somervell County Judge Danny Chambers were among the plant’s most vocal supporters. Others, including Gosslee, expressed concerns over how the aging plant would handle higher risk of #drought, #wildfires and #earthquake activity.
"Since then, Nuclear Regulatory Commission staff have evaluated the environmental impact of running the plant for 20 years after the current licenses expire in 2030 and 2033. The agency issued its draft environmental impact statement in early November, outlining considerations like air quality, land use, water resources, human health and waste management.
"Commission staff determined that Comanche Peak’s continued operation would have only small impacts on the surrounding environment, said Tam Tran, who led the environmental review. The agency defines small impacts as being either undetectable or so minor that they will neither destabilize nor noticeably alter natural resources. [Apparently, these people either believe in #hormesis or don't believe in #bioaccumulation!]
"The review also found that the plant’s operations may affect, but are not likely to negatively impact, protected species such as the #GoldenCheekedWarbler, #TricoloredBat and #MonarchButterfly. Fish habitats are not expected to be affected, Tran said."
