#ClimateSolutions most likely to reach ‘positive tipping points’ revealed by scientists
Global shift towards clean electricity could trigger ‘cascade’ of progress, helping reduce air pollution, cut waste and revive oceans

Thu 10 Sep 2026Excerpt: "The report, produced by the University of Exeter with the Earthshot prize, applies tipping point science to 51 priority areas across five environmental goals: protecting nature, cleaning the air, reviving oceans, eliminating waste and tackling the climate crisis.
"Smith said positive tipping points could be understood as the beneficial counterpart to dangerous climate thresholds, such as the collapse of ice sheets or the death of coral reefs.
" 'Tipping points can also work in our favour,' he said. The rapid growth of solar power, wind power and electric vehicles, as well as the recovery of some natural systems, showed beneficial change could accelerate after reaching a critical threshold.
"However, the transition to clean power is being impeded by slow planning and grid expansion, particularly in wealthier economies, and a severe lack of investment elsewhere. Africa receives less than 2% of global clean energy investment despite possessing 60% of the world’s best solar resources, according to the report.
"Research cited in the analysis suggests coordinated policies supporting clean power, transport and heating could bring forward tipping points in those sectors by between two and eight years. Progress in one sector makes the others easier by increasing demand for clean electricity, encouraging investment and driving costs down further.
"Transforming global commodity supply chains is identified as another high-impact intervention. A relatively small number of #companies, #banks and regulators control trade in commodities including #beef, #soy, #PalmOil, #timber, #cocoa and #coffee, which together drive much of the world’s tropical #deforestation."

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."

A Surprisingly Simple Solution to Protect #Birds From #WindTurbines Gets its Biggest Test Yet
Painting one turbine blade black has shown promise for preventing collisions. Now researchers are seeing if it can work in #Wyoming.
By Kylie Mohr, Summer 2024
"A year ago, a Golden Eagle approaching the Glenrock/Rolling Hills wind farm in Wyoming might have seen a dangerous optical illusion: A turbine’s blades, spinning at more than 150 miles per hour, would appear not as solid objects to be avoided, but as a blur the bird could fly through. Scientists believe this disorienting visual phenomenon, known as motion smear, contributes to the collisions that kill an estimated 140,000 to 679,000 birds per year at #WindFarms in the United States.
"The same eagle soaring over the area’s scrubby sagebrush today will see warning signs. Those once indistinct and innocuous-seeming blurs will present clearly as physical masses, signaling to birds that they should steer clear.
"Such is the hope, anyway, of a study now testing a surprisingly simple tool for making wind farms less hazardous to birds: black paint. This summer, PacifiCorp, which owns the facility, aims to finish painting one blade on each of 36 turbines there. Over the next several years the company and its partners, including the federal government, will keep track of how many eagles and other daytime-flying birds those turbines kill compared to their previous toll and to the remaining 100 or so that have not been painted. Search teams will look for eagle carcasses, while specially trained dogs will sniff out other birds and #bats. 'We’re trying to have as little impact as possible while also trying to provide electricity to customers,' says Jona Whitesides, a spokesperson for PacifiCorp."

6 Ways to Protect #Bats and #Birds From #WindTurbines
By Russell McLendon
Published October 22, 2019"Wind turbines are an important source of clean, #renewable energy. They're one of the fastest-growing power sources in the U.S., outpacing even natural gas. Unfortunately, they also sometimes kill birds and bats.
"That may sound like an environmental Catch-22, but it doesn't need to be. From new designs and smarter locations to high-tech tracking systems and ultrasonic 'boom boxes,' many American #WindFarms are experimenting with various ways to make their turbines safer for flying #wildlife. "

Scientists test #agriculture and #SolarEnergy on #Illinois #farms
Two experiments in the state are measuring which crops could grow well under these panels.
By Juanpablo Ramirez-Franco
Jul 18, 2024, 2:58pm EDT"Thousands of #wildflowers are blooming under rows of solar panels in eastern Illinois. #Milkweeds, #BlackEyedSusans and native #PrairieGrasses catch the sunlight that streams past solar panels on one end of this 54-acre property near Champaign.
"'Obviously, this setting is not perfect for the farming system,' D.K. Lee, a professor of crop sciences at the University of Illinois Urbana-Champaign, said about the narrow space between solar panel arrays.
"But this experimental station called #SolarFarm 2.0 could help UIUC scientists determine whether the marriage between Midwestern agriculture and solar power will be a happy one. Researchers are piloting how crops such as grains and #soybeans used primarily to feed livestock grow with solar panels obstructing their full view of the sun. The counterintuitive practice is called #agrivoltaics, a nascent industry that partners solar developers looking for large plots of land and farmers looking to make additional income.
"That’s why two parallel experiments are underway here to find out what can grow and thrive under solar panels. To hit the ambitious clean energy targets set by state and federal officials, solar power will have to increase close to seven times over current capacity by 2035. That will mean millions of acres devoted to solar power — many of which could be in America’s #farmlands. But to make sure that agricultural communities aren’t left behind by the clean energy transition, scientists want to know what it will take for life to persist beneath solar panels — potentially a first step for farmers and solar power to co-exist.
"'We can only farm about 70% of the land here,' said Bruce E. Branham, professor of horticulture at UIUC. 'So we’ve got 30% of the land that would be farmed in full sun that is just vacant.'
"But in just two years and despite physical constraints, initial findings suggest that the #sorghum grain could be a promising crop to grow alongside solar panels. Branham said that so far it appears that combining sorghum with solar panels has resulted in a 59% increase in efficiency. And wildlife, including #birds and #bees, are flocking to the improved habitat. It’s a good start, but there’s still ways to go before solar farms like these are generating serious energy.
"'This is a 54-acre site, and we’re getting 12 megawatts,' Banham said. 'A lot of power plants are much, much greater than that.'
"In all, Solar Farm 2.0 produces close to 1% of the generating power of the #ClintonPowerStation, a #NuclearPowerPlant just a 45 minute drive east. But for Banham and others, this presents an opportunity to combine Midwestern row crops with solar power to generate enough energy to compete with #FossilFuels and other clean energy alternatives."
