  • The Island Where Everyone Owns the Wind

    Denmark’s Samso Island has not only succeeded in generating 100 percent of its electricity from renewable energy - which is the nation’s goal by 2030 - it is now carbon negative. Locals initially pushed back on the idea of loud and unsightly windmills but had a change of heart when part ownership of the turbines was offered. Samso Island’s success in addressing climate change so effectively was a result of civic participation and the opportunity for economic development.

  • Budget-strapped Wyo towns bypass state with climate efforts

    Several counties in Wyoming are "breaking with state policy" in order to introduce initiatives and efforts aimed at reducing greenhouse gas emissions and mitigating the impacts of climate change. Although the state controls financial allocations, city and county governments as well as community-driven efforts have still resulted in a reduction of electrical consumption and fossil fuel consumption.

  • A System for Sharing Household Heat Is Growing Beneath France

    In Paris, about 7,500 buildings are heated using geothermal energy, a cost-saving and carbon neutral energy source. Water is drawn from deep below ground at a central location and heated by the earth, and then sent via underground pipes to individual buildings. The Bagneux and Chatillon district has scaled up the system, providing heat to over 40,000 people. Districts created joint ventures to reduce construction costs and residents do not notice the energy source shift because when the temperature drops to a point where geothermal energy is not viable, gas boilers automatically keeps the heat flowing.

  • How sunshine can make the railways greener

    As a way to reduce the amount of diesel fuel that powers trains, governments and transit companies around the world are turning to solar panels as a way to utilize renewable energy. In Australia, a solar train launched in 2017 that uses lithium-ion batteries that are charged by solar panels on the roof of the carriages. And a rail line in the United Kingdom uses energy from a solar farm to keep the train running. Scaling solar panels for nation-wide transit systems can be challenging, but many countries are committed to eliminating the use of fossil fuels on their rail networks.

  • Crowdfunded solar puts Red Lake Nation on a path to energy sovereignty

    The Red Lake Nation in Minnesota is building a 240-kilowatt solar array on top of a workforce training center, which will generate about half of the building’s electricity. This project was financed through crowdfunding, where they raised $250,000 from religiously inclined microlenders. The goal: to allow the tribe to have energy sovereignty, create higher-paying jobs, and maintain a healthy environment.

  • A new era in maritime travel: Electric boats

    The Maid of the Mist has given tours of Niagara Falls for 174 years, and recently replaced its fleet with electric catamarans, the first of their kind in North America. The boats are zero-emission and run on dual banks of lithium-ion batteries that are recharged between each tour by plugging two high-voltage lines into a charging station for seven minutes. The charging station is powered by a nearby hydroelectric facility. Two joysticks, like those on an arcade game, allow captains to steer the boats and dual monitors in the wheelhouse provide detailed battery status reports for constant monitoring.

  • Yemen's ‘microgrid girls' power community amid war and COVID-19

    A solar-grid station is powering rural Yemeni communities on the front-line of the war and in the midst of COVID-19, while also empowering women who typically have very few professional opportunities. The microgrid project supplies the community with affordable and clean energy, replacing expensive diesel generators which are bad for the environment. Electricity bills have been cut by 65 percent, an impressive gain in one of the world's poorest country. Thousands of entrepreneurs have generated income based on the new electricity source and many more have benefitted from new services and products available.

  • ‘Energy Aggregation' Has the Potential to Transform How We Get Power, But Hurdles Remain Audio icon

    California communities are turning to “community choice aggregators,” which allows them to buy electricity from green providers and have more control over the energy grid. However, the financial pressure for these programs to offer competitive rates as public utilities can mean that the programs might increase their dependence on cheaper, less green energy sources. So far, 21 of these community-choice programs are in the Golden State, serving 10 million customers.

  • Smart Tourism

    Tourists can travel to remote destinations in the Himalayas and help install solar technology in villages where residents live without electricity. GHE has used funds from the tourism component to electrify 100 villages which increased the quality of life for residents and resulted in an opportunity for tourism where one did not exist before. As a result of the electrification, a community tourism initiative allowed for tourists to stay with villagers and provided an addition source of income. The economic stimulus from tourism gave native youth a reason to stay in their villages instead of migrating.

  • Bringing the chill of the cosmos to a warming planet

    SkyCool Systems manufactures panels that can be incorporated into existing cooling systems to reduce the amount of electricity needed to turn hot air into cold air. The technology is based on radiative cooling and utilizes a thin, mirror-like film engineered using nanotechnology to send heat into space while absorbing almost no radiation. It lowers the temperature of objects by more than 10 degrees and doesn’t require electricity or special fuels, so it does not produce greenhouse gases. While piloting the panels, a grocery outlet saved over $3,000 in electricity costs over the course of just one summer.
