Solar power at US schools surges, growing fourfold over the last decade

Posted by in categories: education, solar power, sustainability

Since 2014, solar capacity at K-12 schools has more than quadrupled across the US, according to a new report from clean energy nonprofit Generation180.

The “Brighter Future: A Study of Solar on K-12 Schools” report highlights that over 6.2 million students – more than 1 in 9 – now attend schools powered by solar. In 2023 alone, more than 800 schools added solar panels, meaning that at least one school went solar every single day during the 2022–23 school year.

“The benefits of solar energy are now reaching a broad range of schools across the country, including those in under-resourced communities that stand to gain the most from the cost savings and educational opportunities that solar technology provides. We want all schools and communities, regardless of their size, geography, or wealth, to have access to affordable, clean energy,” says Tish Tablan, the report’s lead author and senior director of Generation180’s Electrify Our Schools Program.

China prepares to change world with introduction of revolutionary nuclear power station: ‘This design significantly reduces the chances of meltdowns’

Posted by in categories: nuclear energy, sustainability

Thorium may sound like something out of a Marvel comic book, but the radioactive metal could provide a very real, renewable energy source.

Chinese scientists have been working on a molten salt nuclear power plant using thorium for years. They even created a prototype reactor in 2021, according to the International Atomic Energy Agency.

Massive Solar Wind Disturbance caused Earth’s Magnetosphere to Fly Without its Usual Tail

Posted by in categories: particle physics, space, sustainability

Like a supersonic jet being blasted with high-speed winds, Earth is constantly being bombarded by a stream of charged particles from the sun known as solar wind.

Just like wind around a jet or water around a boat, these solar wind streams curve around Earth’s magnetic field, or magnetosphere, forming on the sunward side of the magnetosphere a front called a bow shock and stretching it into a wind sock shape with a long tail on the nightside.

Dramatic changes to the solar wind alter the structure and dynamics of the magnetosphere. An example of such changes provides a glimpse into the behavior of other bodies in space, such as Jupiter’s moons and extrasolar planets.

Increasing Environmental Stressors Decrease Ecosystem Resilience

Posted by in categories: climatology, sustainability

What influence do global environmental stressors have on the ability of an ecosystem to withstand these stresses and rebuild itself? This is what a recent study published in Nature Geoscience hopes to address as an international team of researchers investigated a correlation between environmental stressors and ecosystem resilience. This study comes as climate change continues to ravage the planet with more severe and frequent weather patterns, including increased temperatures and storms. This study holds the potential to help researchers, climate scientists, and the public better understand the short and long impacts of climate change on the environment and the steps that can be taken mitigate them.

“Terrestrial ecosystems are subject to a myriad of climate change and environmental degradation factors, including global warming, drought processes, atmospheric pollution, fires or overgrazing among many others. We know that these global change factors impact the ability of our ecosystems to provide services such as carbon sequestration or soil fertility that are key in the fight against climate change and in food production.” said Manuel Delgado Baquerizo, who leads the Biodiversity and Ecosystem Functioning Lab (BioFunLab) leader and is a co-author on the study.

For the study, the researchers conducted a global and elaborate study combining approximately 14,000 observations regarding ecosystems functions and biodiversity from a 15-year study with the goal of ascertaining an ecosystem’s ability to resist global environmental stressors, including those resulting from climate change. In the end, the team discovered a negative correlation between environmental stressors and an ecosystem’s resilience, meaning as these stressors increase the resilience of an ecosystem decreases. Additionally, they found the opposite regarding biodiversity, meaning its resilience increases to increasing global environmental stressors.

Resin made from biomass advances method for manufacturing recyclable wind turbine blades

Posted by in categories: chemistry, sustainability

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) see a realistic path forward to the manufacture of bio-derivable wind blades that can be chemically recycled and the components reused, ending the practice of old blades winding up in landfills at the end of their useful life.

The findings are published in the journal Science. The new resin, which is made of materials produced using bio-derivable resources, performs on par with the current industry standard of blades made from a thermoset resin and outperforms certain thermoplastic resins intended to be recyclable.

The researchers built a prototype 9-meter blade to demonstrate the manufacturability of an NREL-developed biomass-derivable resin nicknamed PECAN. The acronym stands for PolyEster Covalently Adaptable Network, and the manufacturing process dovetails with current methods.
