  • Here comes the sun canoe, as Amazonians take on Big Oil

    The Kara Solar Foundation is looking to connect indigenous communities in Achuar territory in Ecuador to learn about solar power as an alternative to oil. By building solar-powered canoes, they can replace vessels that burn fossil fuels into the atmosphere. While the two boats in operation have run into technical problems, the intercultural training programs are instructing Achuar people on how to fix the technology. “Sustained and truly intercultural collaborations can create technological solutions that serve indigenous communities, rather than destroying them,” says Oliver Utne, the foundation's founder.

  • In Kenya, herders turn an invasive cactus into biofuel

    The invasive prickly pear cactus is spreading over grazing lands in Kenya and is harming herders’ livestock. So a local environmental science graduate is testing a system to turn the cacti into biogas. While the system can be expensive to install, the gas can be used for cooking and fertilizer, which can free up time for pastoralists and reduce the amount of firewood used. The graduate is training eight women’ groups to use the system.

  • 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.

  • How Farms Turn Food Waste Into Renewable Energy

    Food waste diverted from the landfill to anaerobic digesters can be used to create electricity. In Massachusetts, farmers and businesses participate in a waste-to-energy project in partnership with Vanguard Renewables. Discarded food waste is mixed with cow manure and fed into a digester. The gasses created are then used to power electric generators.

  • Can rationing carbon help fight climate change?

    As countries wrestle with how to reduce their carbon emissions, grassroots carbon rationing experiments are taking shape around the word. On an Australian Island of 800 people, a quarter of them participated in a test that calculated their carbon footprints with a goal of reducing their fossil fuel use by 10 percent. The average household reduced their usage by 18 percent and almost two-thirds of participants wanted to continue. Other experiments in Finland and the United Kingdom have taken place, yet some question if carbon rationing is equitable.
