  • MPHS Entrepreneurship Club tackles energy efficiency with light replacement project at high school

    The Entrepreneurship Club at a high school in Grand County, Colorado took the initiative— and a $2,000 grant from the Grand Foundation— to replace all of the lights in their school with energy-efficient LED lights. Tristan Schwab initiated the project after learning about the divide in energy efficiency between urban and rural areas. The students reinstalled 200 lights in their building and, once the school has improved its efficiency and saved 40% on electric bills, plan on installing solar panels to further their work.

  • Waste to Wealth: How Kenyan farmers are bringing life back to degraded Lake Victoria swamps

    Families living in the wetlands of Lake Victoria in Kisumu, Kenya are working together with a nonprofit called Ecofinder Kenya to protect and conserve the wetlands they live on. The crux of the incentive centers around the Eocfinder toilet, which converts human and animal waste to biogas, but they also work with solar lamps, water pumps, and a "farmer-to-farmer" program in which farmers share environmentally-friendly expertise. The program has been going on for 3 years now, and the wetlands have since seen a return of wildlife and growth, particularly with fish and birds.

  • Pittsburgh's ‘living building' focuses on eco-friendly construction

    Creating sustainable buildings requires rethinking many of the norms in construction and city planning. The Center for Sustainable Landscapes, part of the Phipps Conservatory in Pittsburgh, Pennsylvania, received the first Living Building Challenge (LBC) certification. To achieve this, CSL advocated for changes to Pittsburgh’s laws on the use of public water utilities. CSL also had to seek out construction materials that avoided the use of harmful chemicals-a task easier said than done.

  • This new recycling innovation could help fix our broken trash system

    A common type of plastic, Polypropylene, is usually “downcycled” - meaning it makes lower quality materials when recycled. A new innovation in recycling will allow it to be recycled into “virgin” material that is cost- and energy-effective and will have a broader range of uses, increasing the likelihood that plastic will end up in new material and not in a landfill. PureCycle Technologies has had such successful pre-sales that the first plant has 20 years worth of pre-orders.

  • Ikea's innovation lab unveils a plan to help people cash in on solar energy

    Ikea's innovation lab, Space10, piloted a block-chain powered solar energy grid as a way to creatively save money on electricity and create a sustainable energy alternative. Other microgrids around the world have seen success in allowing people who are part of the system to sell their excess energy and only use what they need.

  • These shipping container farms will soon be in grocery store lots across the U.S.

    A direct line from local producer to consumer reduces carbon emissions and strengthens community food systems. A partnership between farming tech company Square Roots and Gordon Food Services aims to create local food supply chains by placing cargo-container hydroponic farms directly at store sites and distribution centers. The plan is inspired by the success of Square Roots’ container farms in Brooklyn, NY.

  • Swedish technology could make geothermal as mainstream as wind and solar

    Geothermal power is typically hard to scale due to its dependence on hot water. Climeon is a Swedish energy company changing the game. It uses low-temperature heat and sells its energy in modular units, which makes it affordable. Due to an infusion in capital, the company is scaling its energy distribution across the globe.

  • Going Dark to Reconnect to the Night Sky

    Light pollution threatens access to nature and its views of the stars, but it also negatively impacts health by disrupting sleep and human circadian rhythm. The International Dark-Sky Association has been working for years “to protect naturally dark sky,” educate others, and increase engagement with the stars.

  • Scientists just figured out how to turn CO2 back into coal

    Researchers in Australia have discovered a way to capture CO2 from the air and turn it back into solid carbon. The new method uses liquid metal and electricity to process the CO2 and store it at room temperature – something that until now had not been possible. Scientists say it shows potential for large scale use – in combination with sustainable energy – as the world continues to grapple with the effects of climate change.

  • You can now ski on top of a $670 million power plant in Copenhagen

    Amager Bakke is a powerplant in Copenhagen that is designed to get residents of the city engaged in a conversation about where waste goes, all while burning up to 400,000 tons of waste a year, powering 60,000 homes, and heating 160,000 homes. In 2013 the local plant was redesigned to burn the city's waste and encourage interaction by building a ski slope atop the plant, a hiking trail, and an elevator that introduces education about waste management. Amager Bakke is still new and experimental, so its long-term success is still unclear, and it is not completely emission-free yet.
