  • A New Weapon Against Climate Change May Float

    Floating wind turbines off the coast of Portugal is one of the latest experiments to convert wind energy into electric power. These machines can generate electricity for a city of up to 60,000 people. While it will take more financing and time to scale the project, investors are impressed with the results and see it as a viable financial return to combat climate change.

  • How Big Tech is Reshaping the Power Grid

    As part of a deal with Facebook to build a data center in New Mexico, an electric utility is investing in renewable energy to power the center. Through power purchase agreements, which are contracts to buy renewable energy, the social media company is accelerating the state’s transition away from fossil fuels. These contracts often come with large tax breaks for companies, but Facebook will help finance $800 million worth of wind and solar installations that can generate 396 megawatts of power. These agreements can also be implemented in other states who are hardest-hit by the decline of coal consumption.

  • Terrapin Powers Brewery With the Sun, Thanks to Georgia Bill

    Terrapin Beer Co. is powering their brewery with solar power, approximately 30 percent of the business’ total energy. The brewery partnered with Cherry Street Energy, a third-party solar ownership company, which allows them to rent the solar panels for little upfront cost. However, this arrangement doesn’t allow the brewery to store solar power for future use. These efforts allow the business to rely more on renewable energy to reduce their carbon footprint.

  • Poop may tell us when the coronavirus lockdown will end

    Researchers and public health experts across the world are turning to "wastewater-based-epidemiology" as a practice that could help trace and track the spread of COVID-19. This methodology has already proved successful in helping mitigate diseases such as polio in Israel and track the usage of illicit drugs in Australia. Most recently, in both France and the Netherlands, early sewage samples have revealed useful data about the coronavirus outbreak.

  • University of Notre Dame converts tons of dining hall leftovers into energy

    The University of Notre Dame installed three Grind2Energy systems, which aims to reduce the amount of food waste from the campus’ dining halls. The systems process the waste and send it to a local dairy farm where they break down the material to produce biogas that is used to generate electrical power for 1,000 homes each day in Plymouth, Indiana. While not everyone at the university has committed to the sustainability efforts, these systems can be scaled to be used on other college campuses.

  • Beer Waste Helps Montana Town Save Money On Water Treatment

    Finding ways to reuse brewery waste can save water treatment plants money. In Havre, Montana, Triple Dog Brewing has entered into a partnership with the town’s wastewater treatment plant, supplying discarded barley to feed the plant’s microbes. The barley replaces commercial bacteria feed, which would have cost the plant thousands of dollars. The town was also able to avoid having to do costly upgrades to its water treatment plant. Other towns are looking to this process for inspiration.

  • Havre's Wastewater Woes Solved By Beer

    Upcycling spent barley helps to ease wastewater treatment. In Havre, Montana, the town’s wastewater treatment plant uses barley from a local brewery, Triple Dog Brewing, to feed bacteria. The nutrients from the barley give the bacteria a boost, helping to reduce nitrogen and phosphorous levels in the water. The collaboration means that Havre can save on expensive solutions and upgrades to its wastewater treatment plant.
