Every year, people around the world drink enormous amounts of coffee, leaving behind more than 10 million tons of used coffee grounds. Most of this waste ends up in landfills or is burned, contributing to greenhouse gas emissions and environmental pollution. However, used coffee grounds contain a significant amount of energy. The problem is that […] The post Scientists turn wet coffee grounds int…

The material I am hoping to discuss and find answers to is based around the future-proofing of ocean voyages using both solar and hydrogen as power sources. I have a concept I will be laying out on paper over the next 12 months of a Trimaran with two electric motors which, if I can solve the one... Read more

A Researcher team at the Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed a technology that converts wet spent coffee grounds directly into high-quality biochar in just 90 seconds, no drying or oil removal required.

As datacenters’ connections to electric grids are held up, big tech is forced to throw money at producing its own power Datacenters are driving unprecedented growth in the US clean energy industry, paradoxically boosting a sector that was sputtering before the artificial intelligence boom even as AI’s rollout creates immense environmental challenges. However, observers caution that while the cent…

Chemist Tsutomu Miyasaka will receive the 2026 Kyoto Prize in Advanced Technology for his contributions to the development of perovskite solar cells.

One of the largest clean energy projects in United States history is now online, delivering electricity from a massive wind farm in New Mexico to Arizona and California.

Vertoro, a renewable oil company, has announced the first closing of its €17 million Series B round, consisting of €10 million in newly contributed capital and €7 million in converted loan notes. Climate Tech Partners, Invest-NL, and Maersk participated as key investors, with further contributions from Energietransitiefonds Rotterdam, LIOF, SHIFT, and Chemelot Ventures. The round will primarily f…

Building roofs are advancing through a multidimensional optimization process that encompasses technological innovations, new materials, energy-saving performance, and faster construction methods. From green roofs and rainwater harvesting systems to solar panels , contemporary architects are working to balance aesthetics, performance, durability, and environmental impact in their projects. Roof re…

Researchers in Japan have developed a new artificial photosynthesis system that can produce solar fuel more reliably under changing sunlight conditions without using batteries. The team from Osaka Metropolitan University says the technology could make solar fuel systems simpler, cheaper, and more practical for everyday use. Artificial photosynthesis is inspired by the process that plants […] The …

This is a re-post from Yale Climate Connections by Ben Tracy, Climate Central If you feel like your electricity bill just keeps climbing, you aren’t imagining it. Since 2020, U.S. residential energy prices have surged by about 30%, making power the largest household energy expense behind gasoline, according to the U.S. Energy Information Administration. But for residents like Alex Curtis, the day…

With an initial capacity of 24 megawatts, the innovative data center uses seawater as a natural cooling system.

Summer 2026 is going to be a hot one, but a new report shows that solar energy is helping America’s electric grid handle the strain. The post Thanks to solar, electric grid more prepared for summer heat appeared first on Environment America Research & Policy Center .

Firm becomes latest carmaker to roll back on move away from fossil fuels with push for US sales growth and making more hybrid petrol models Jaguar Land Rover has U-turned on plans to shift one of its factories to making only electric cars as part of an effort to focus on growth in the US, as Britain’s largest carmaker further rowed back on the transition away from fossil fuels. The manufacturer t…

Substantial economic growth in growing countries has increased climatic difficulties in recent decades, endangering sustainability and the environmental quality. As a result, renewable energy usage, technical innovation, natural resources, and carbon pricing schemes have become important instruments for reducing the environmental impact and promotion green economic expansion. The 2030 Sustainable…

Solar supplied 12.8% of U.S. electricity last month while coal accounted for 12.2%, according to a report from the clean energy think tank Ember.

This spring, I had the opportunity to teach the Alternative Energy Science course at the Arava Institute together with Dr. Tareq Abu Hamed. While the course introduced students to renewable energy technologies such as solar energy, wind power, biomass, hydrogen, energy storage, and hybrid systems, one of the most important lessons that emerged throughout the […] The post Energy Beyond Technology:…

The report states that ground-mounted solar systems, which dominate India’s roughly 100 GW of installed solar capacity, require three to four times more area per megawatt than the panels themselves occupy

Legal victories have dampened the Trump admin’s efforts to halt wind and solar power.

Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. You can submit claims you think need checking via the tipline . Does solar energy need subsidies to compete with fossil fuels? Unsubsidized utility-scale solar is now generally cheaper than building fossil fuel power plants. Costs are often compared using “levelized cost of energy,” t…
