  • This entrepreneur is plugging the world's drinking water into the (digital) cloud

    “In 2015, nearly 21 million U.S. residents relied on water systems that violate the standards set by the federal Safe Drinking Water Act.” Meena Sankaran is helping to reverse the trend. Her startup, KETOS, uses analytics and sensors that provide real-time data that can be sent through a mobile app. Instead of having to wait for people to monitor and process the data, or for people to get sick, data can be delivered instantaneously. “So far, the company has compiled 13 million data points from municipalities across all 50 states, spanning the last 18 years.”

  • Why Las Vegas Is at the Heart of Western States' Water Conundrums

    After running out of water during a drought in 2002, the Southern Nevada Water Authority and Las Vegas Valley Water District took proactive steps to conserve the region’s water for future generations. Thanks to public service campaigns, outdoor water usage limits, and turf replacement programs, the region’s water usage per capita has dropped by 46 percent. However, many people still don’t fully comply with the city’s water regulations and the region continues to grow at an expanding rate. Yet, similar conservation efforts could be a model for other arid regions around the United States.

  • 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.

  • How conservation groups confront distrust from communities of color

    For environmental groups like Conservation Colorado looking to expand their reach, they’ve learned that they need to rebuild relationships and trust with communities that have historically been excluded from conservation conversations and take the time to understand the issues directly impacting them. Once they’ve taken those steps, Conservation Colorado was able to work with an all-women’s Latina group to prevent a waste treatment plant from expanding into their community.

  • 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.

  • Pee fanatics want to feed the world with your liquid gold Audio icon

    A French startup is turning urine into an environmentally-friendly fertilizer that could replace chemical products. Early tests suggest that the urine mixture created by Toopi Organics can compete with synthetic fertilizers, which end up in waterways and can alter lake and river ecosystems. While the organic fertilizer requires a significant amount of urine to make, it could be a viable alternative to grow crops.

  • 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.

  • Cooperating over shared water in West Africa

    There are over 250 rivers and lakes that are shared between countries, accounting for more than half of world's freshwater. This means that countries have to cooperate to share resources. In 1972, Mali, Senegal, and Mauritania did just that. They formed the Senegal River Basin Development Authority, or the OMVS (for its French initials). In 2005, Guinea joined. The organization is an example of how countries can join forces to share water resources cooperatively.

  • Locals Question the Relevance of First Solar Power Plant in Soroti

    Four years later after a solar grid was installed in Uganda, residents of nearby villages are wondering when they will get some of that power. The 10-megawatt facility, which cost $19 million to build, was expected to provide electricity to about 40,000 homes, schools, and businesses in the area. However, almost all households in the 10 surrounding villages still use firewood for cooking. The lessons learned from this renewable energy project could help inform others as the country looks to power more parts of the country with solar panels.
