"Chemists at Kaunas University of Technology (KTU), #Lithuania have synthesized materials that can improve solar elements for indoor use. Such photovoltaic cells, which can also be integrated into various electronic devices, generate electricity even in #LowLight conditions.

"Their study is published in ACS Applied Materials & Interfaces.

"Consumption of oil and gas results in an increase of atmospheric temperatures, leading to global #ClimateChange, currently labeled a #ClimateCrisis. To combat this problem, efforts are being made to use #renewable and environmentally friendly energy sources such as #wind, water and #SolarPower.

"'Wind and #hydropower energy are constrained by high costs and location dependency, while solar energy is flexible, efficient and relatively inexpensive. However, the energy from indoor light sources and natural light entering through windows is lost every day,' says Juozas Vidas Gražulevičius, Professor at the KTU Faculty of Chemical Technology and Head of the Chemistry of Materials research group.

"According to Prof. Gražulevičius, this can be solved by indoor #photovoltaics, which generate electricity even in low-intensity light conditions."

Falls Planning Board to weigh zoning change to spur #LoveCanal #SolarFarm

by RICK PFEIFFER | Jul 31, 2024

"The #NiagaraFalls Planning Board is expected to decide in September whether to recommend a zoning change that would allow the site of the worst #EnvironmentalDisaster involving #ChemicalWastes in U.S. history to be transformed into a large-scale, eco-friendly, #solar #RenewableEnergy project.

"Just three residents from the Love Canal neighborhood appeared at a board hearing Wednesday night on a request by city officials and the New York State Energy Research and Development Authority (#NYSERDA) to change the zoning of 16 acres of city-owned land, south of Colvin Boulevard, north of the LaSalle Expressway and between 93rd and 95th streets from R1-A (Single Family Residential) to OS (Open Space). The change would allow for the land that was once #HookerChemicalCompany’s Love Canal landfill to be reclaimed and developed into the Vincent Welch Build-Ready Solar project.

"That land was also once the location of the Griffin Housing Development [YIKES!] as well as the Love Canal."

CHESAPEAKE, Va. — "At #SolarFarms in #Chesapeake and #VirginiaBeach, Dominion Energy has found an alternative option to a lawn mower; this one has hooves.

"'It’s an environmentally-friendly alternative, it’s innovative, it’s creative and they do a great job,' said spokesperson Tim Eberly. 'They can eat about 40 acres of grass and vegetation every few days.'

"The flock of 300 sheep and 180 lambs is tended to by a shepherd, along with guard dogs and herding dogs.

“'Our guardian dogs are with the sheep all the time," said Jess Gray with Gray's #Lambscaping. 'They protect the flock when we are not around.'"

[..]

"The goal of the project is to keep the grass below the panels to maximize output. At Bedford #SolarFarm in Chesapeake, one of the sites where the sheep currently graze, the energy generated powers 17,500 homes."

So, once again, I'm going to try and shift gears and post some positive stories about solar energy and #renewables (and boost some #SilentSunday images). If there is #BreakingNews, I'll be posting about that, but I'm going to try and take a break from the doom and gloom for a bit. #SolarSundays #SolarSunday #Bloomscrollng #NaturePhotography
I am going to attempt to dedicate Sundays to #SilentSunday images and posts about #RenewableEnergy -- you might call them #SolarSundays. Trying to take a break from all the #DoomPosting -- but, you know, if there's breaking news, I might have to shift gears. I hope some folks are into it. I think we could all use some good news and timeline cleanses once in a while.

Closed loop? Reused #SolarPanels to power solar panel #recycling facility

Sean Wolfe
7.26.2024

"#SolarCycle, a solar recycling company, has installed an on-site solar farm made of reused solar panels that will power its industrial solar panel recycling facility.

"The reused panels come from decommissioned utility-scale solar farms and residential installations across the United States. SOLARCYCLE says the project serves as a model of how to power an industrial facility through renewable energy as the US ramps up domestic manufacturing capacity. It will also help to build a fully closed loop, ultra-low carbon solar industry in America.

"The 500KW system made from around 1,000 reused panels will provide around 50% of the electricity SOLARCYCLE uses to power their advanced recycling factory in #OdessaTexas. SOLARCYCLE’s plan is to expand this secondhand power plant to continue to generate more of the company’s energy demands, including its facilities in #MesaArizona, and #CedartownGeorgia. Two of SOLARCYCLE’s customers provided a significant percentage of the secondhand solar panels in use — #Ørsted from their own Texas utility-scale operations and #Sunrun, from their residential operations.

[...]

"Earlier this year, SOLARCYCLE announced it would invest an estimated $344 million into a new #SolarGlass manufacturing facility in #CedartownGeorgia. The company said it would be the 'first-of-its-kind' in the United States to use recycled materials from retired solar panels to make new solar glass.

"The facility will be located in Cedartown North Business Park, a Georgia Ready for Accelerated Development (GRAD) certified site in Cedartown. The plant, which will be the first of SOLARCYCLE’s facilities to manufacture glass in addition to recycling solar panels, was scheduled to begin construction this year and is expected to be operational in 2026.

"SOLARCYCLE currently operates two solar panel recycling facilities in the United States and says its recycling technology allows it to extract up to 95% of the value from used solar panels. SOLARCYCLE’s new plant in Georgia will make the company one of the first manufacturers of specialized glass for crystalline-silicon (c-Si) #photovoltaics in the U.S., with the capacity to make 5 to 6 GW worth of solar glass every year, it said. The glass will be sold directly back to the domestic solar manufacturers.

"Solar photovoltaics are often recycled the same way as glass, cars, computer monitors, TVs, or lighting, but the process only recovers about 80% of PV materials. Nonspecialized recycling is one of the challenges to achieving a circular economy for solar photovoltaics.

"While the moral incentive to recycle solar panels is clear, little financial incentive exists today. Recycling a solar panel ranges in cost from $20 to $30, while dumping the same panel in a landfill runs $1 to $2 – but SOLARCYCLE believes the cost to #landfill to be much higher when factoring in logistics costs."

Cutting #forests for #SolarEnergy ‘misses the plot’ on #ClimateAction

By Matthew Lynch
July 26, 2024

"As the world grapples with the urgent need to address #ClimateChange, the transition to renewable energy sources is often presented as a silver bullet. Solar energy, in particular, is championed for its potential to reduce #GreenhouseGas emissions and provide a sustainable alternative to #FossilFuels. However, a disturbing trend is emerging: in the quest to establish new solar farms, some regions are cutting down forests, raising questions about whether these actions truly serve the cause of climate action.

The Dilemma of Land Use

"The push for solar energy has led to significant land-use changes across the globe. In some cases, this has meant the clearing of large forested areas to make way for solar installations. Proponents argue that converting forest land into solar farms can produce clean energy and reduce dependency on non-renewable sources. However, this perspective overlooks the critical role that forests play in the global climate system.

"Forests act as vital #CarbonSinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass and soil. When these forests are cleared, not only is this carbon storage capacity diminished, but the act of deforestation itself releases stored carbon back into the atmosphere, exacerbating climate change. In essence, the emissions produced by cutting down trees can offset the climate benefits of the solar energy generated on that land for years, if not decades.

#Biodiversity Concerns

"Beyond carbon emissions, cutting forests for solar farms poses a significant threat to biodiversity. Forests are home to a multitude of species, many of which are already endangered due to habitat loss, climate change, and human activity. The conversion of these habitats into solar farms disrupts ecosystems and can lead to local extinctions. The loss of biodiversity has far-reaching consequences, affecting ecosystem services such as #pollination, nutrient cycling, and #water purification, all of which are crucial for human survival.

A Holistic Approach to #RenewableEnergy

"The key to achieving meaningful climate action lies in adopting a holistic approach to renewable energy development. Rather than viewing solar energy installations solely through the lens of energy production, it is essential to consider the #environmental and #social implications of land-use decisions. This includes prioritizing #brownfield sites, such as abandoned buildings, #industrial lands, and degraded areas, where solar installations can occur without harming forests and other critical #ecosystems.

"Moreover, a combination of strategies should be pursued to maximize the benefits of solar energy while minimizing ecological impact. This could involve integrating solar panels into existing structures, promoting community solar projects, and investing in research on #agrovoltaics, which combines #agriculture with solar energy generation. Such approaches can help meet energy needs while preserving #NaturalLandscapes and promoting #biodiversity."
