Born in a Flood: The Epic Story of the Controllable Grid Interface

NREL Researchers Celebrate 10 Years of Replicating Grid Events To Strengthen Renewable Energy Technologies In September 2013, a team of National Renewable Energy Laboratory (NREL) researchers, led by Vahan Gevorgian and Robb Wallen, faced a looming deadline. Not only did the brand-new 5-megawatt (MW) dynamometer need to be up and running, connected … [continued]

Recyclable, Plant-Based Material Could Take a Spin on Next Generation of Wind Turbines

About three years ago, National Renewable Energy Laboratory (NREL) researchers Robynne Murray, Nicholas Rorrer, and their team set out on a mission to make an easily recycled resin to serve as the central glue holding a wind turbine blade together. They began by formulating their resin in thimble-sized vials at the lab … [continued]

New Volkswagen Tech Helps Prevent Dooring Bicyclists

One of the arch enemies of bicyclists in cities is doors, car doors. When the lane for bikers is right next to parallel-parked cars, there’s a serious risk of drivers and passengers opening the car door right at the wrong time and bicyclists crashing into it, even flipping over the … [continued]

Yet Another Oil Spill Hits the Gulf of Mexico

The largest Gulf oil spill since Deepwater Horizon highlights the inherent risks of offshore drilling to coastal communities and marine ecosystems. A new large oil spill hit the Gulf of Mexico on November 16. This disaster is a stark reminder of the constant risk that offshore drilling poses to wildlife, ecosystems, and … [continued]

COP28 Climate Funds Pledge Tracker

Keep track with COP28 pledges to UN funds that help developing countries reduce greenhouse emissions and address the impacts of climate change. Debates about funding are always a major feature of UN climate negotiations. The big injustice of the climate crisis is that the poorest and most vulnerable communities, who … [continued]

New Renewable Fuel Standard Volume Targets Facilitate Renewable Natural Gas Production

On June 21, 2023, the U.S. Environmental Protection Agency (EPA) announced a final rule that established biofuel volume requirements and standards for cellulosic biofuel for 2023–25 as part of the Renewable Fuel Standard (RFS) program. The cellulosic biofuel category primarily applies to Renewable Natural Gas (RNG), a form of natural … [continued]
