A new report on the solar industry warns “the time is now” to implement circular economy measures that help it meet government Net Zero targets. The report “From Linear to Circular: Evidence from the UK solar sector” highlights a number of circular economy initiatives that are leading the way, including a project where used car […]

Nearly two weeks after Hurricane Helene downed power lines and washed out roads all over North Carolina’s mountains, the constant din of a gas-powered generator is getting to be too much for Bobby Renfro. It’s difficult to hear the nurses, neighbors and volunteers flowing through the community resource hub he has set up in a […]

Made from renewable materials like biomass and agricultural waste, sustainable aviation fuel has enormous potential to decarbonize the aviation industry. But widespread adoption has yet to take off. Sustainable aviation fuel (SAF) makes up less than 1% of the fuel used in the aviation industry, while aviation fuel contributes about 3% of global greenhouse gas (GHG) emissions. Producing […]

Widespread coverage of building rooftops with conventional photovoltaic solar panels may increase temperatures on hot days and lower them at night, says new modeling The research led by Dr. Ansar Khan from the University of Calcutta and co-authored by UNSW Sydney Scientia Professor Mattheos (Mat) Santamouris used mesoscale (weather system) simulations due to the absence […]

MIT engineers have built a new desalination system that runs with the rhythms of the sun. The solar-powered system removes salt from water at a pace that closely follows changes in solar energy. As sunlight increases through the day, the system ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, […]

The National Renewable Energy Laboratory (NREL) has developed a first-of-its-kind tool that enables hydropower operators and developers to estimate the greenhouse gas emissions associated with building and operating closed-loop pumped storage hydropower (PSH) facilities. Closed-loop PSH generates and stores electricity by moving water between an upper and lower reservoir. It is an established technology that […]

Swedish company NoviOcean has tested a third-gen prototype of its combination wind/solar/wave energy platform, a floating platform rated for up to 1 megawatt of consistent clean energy around the clock thanks to a fascinating buoyancy-driven mechanism. Next step: a full-scale pilot. This renewable energy platform will have a relatively small footprint once built at full […]

Norway’s Equinor (EQNR.OL), opens new tab has bought a 9.8% stake valued at around $2.5 billion in Danish offshore wind farm developer Orsted (ORSTED.CO), opens new tab, it said on Monday, as it seeks to build up its renewables portfolio. Orsted shares have dropped 69% from their 2021 all-time high as the offshore wind sector has faced surging […]

Swedish engineering consultancy company Sweco said it would design one of Europe’s largest battery energy storage systems, called Green Turtle, in Belgium. Sweco is designing the battery park on behalf of the company GIGA Storage Belgium. WHY IT MATTERS: Sweco said the park would make a significant contribution to the energy grid by providing stored […]

Residential solar and battery storage marketplace EnergySage just released its latest insights report for H1 2024 – here are 3 of its top-line findings. EnergySage* provides quotes to solar shoppers across 50 states and Washington D.C., so it gets great insight into what’s happening in the residential solar and battery storage sector. The “19th EnergySage […]
