  • Smart Grid Experiment Saves Participants the Equivalent of One Electric Bill Per Year

    Gamifying energy-efficient behavior can help consumers adjust their habits. Project GresBAS (Grid Responsive Society through Building Automation Systems) incentivizes consumers by allowing them to compete against their own personal records, as well as their neighbors. The Project has piloted studies in Turkey and Portugal, signaling the broader possibilities of gamifying user interactions with smart grid technologies.

  • Africa Embraces an $8 Billion Solar Market for Going Off-Grid

    Many African "off-grid" countries, where as many as 80 percent of populations lack reliable access to electricity, are turning to a low-cost, environmentally friendly model: solar-powered, pay-as-you-go LEDs. Cheaper and more eco-friendly than alternatives like kerosene or diesel fuel, the LEDs like the one M-KOPA make boast 600,000 customers across East Africa. The technology has the sharp reduction in solar panel and battery cost to thank for increased access.

  • Western Water Managers Bet On Cloud Seeding, Despite Gaps In Science

    In the American Southwest, state water managers have been investing for decades in weather modification programs, otherwise known as "cloud seeding." Colorado River Basin states recently agreed to expand that effort, hoping to build crucial snowpack. But some scientists are skeptical that cloud seeding can produce reliable supplies, citing huge data gaps.

  • How Poop-Eating Worms Could Help Save Thousands Of Lives Each Year

    The Bill Gates Foundation is currently funding a number of organizations that seek to solve the rate of open defecation by creating low-cost toilets that utilize the feces within them. One organization, called Sanergy, operates in 11 neighborhoods across Nairobi and uses a systems-based approach that takes into account financing and maintenance of the toilet as well as selling the waste as fertilizer. Another, called Tiger Toilets in India, uses a septic tank toilet that places worms within the drainage layer who then consume the feces and produce fertilizer to be used or sold.

  • Dutch eco initiative halves energy bills in first UK homes

    By piloting a Dutch initiative to make homes more energy efficient with new windows and solar panels in the United Kingdom, tenants are seeing their monthly energy bills decrease by almost half. More than 150 social housing homes in Nottingham are testing the “Energiesprong” approach, which has already seen success in the Netherlands.

  • The key to easing land-use disputes? Listening, says Virginia solar developer

    In Virginia's Prince William County, one solar developer shows that the key to community support for renewables may be dialogue. Virginia Solar, a Richmond-based energy company, has won approval for a 20-megawatt solar project near Nokesville. How? By listening to citizen concerns about conservation, property values, and construction.

  • Solar Mini-Grids Give Nigeria a Power Boost

    Over half of Nigeria's population lacks reliable access to electricity, but solar energy is slowly changing this. Mini-grids are gaining popularity in these rural areas thanks to the technology's capability to provide affordable electricity while also reducing harmful emissions.

  • Is clean energy funding from the UN's Green Climate Fund and other sources going where it's needed most?

    The UN's Green Climate Fund is a mechanism through which money for climate adaptation and mitigation is distributed globally. But funding for renewable energy goes overwhelmingly to wealthier nations. Without more funding, it's unlikely that poorer, less developed countries can meet their 2015 Paris Climate Accord goals.

  • From German trains to South Korean buses, hydrogen fuel is back in the energy picture

    Hydrogen fuel has made promising strides from Germany to Japan, thanks to shifting markets for renewables, improved storage technologies, and emissions-reduction goals. Electrolysis that uses renewables to make the fuel could transform transportation and energy infrastructure, but a few concerns about the unintended effects persist.

  • E-rickshaws as antidote to air pollution: Hope for Bengaluru or pipe-dream?

    In Bengaluru, switching from rickshaws to electric autos could help reduce noise pollution and greenhouse gas emissions by as much as 0.11 million tons each year. But the policies that encourage electric autos only exist, largely, on paper.
