  • Cleaning up Cambodia's kitchens could curb deforestation, climate change

    In Cambodia 2.5 million people use stoves fueled by forest biomass; charcoal and wood. The emissions caused by using biomass are extremely harmful not only to people but also to the environment. The emissions caused by biomass globally are equal to those of the aviation industry. To counter the problem, several organizations and companies are providing alternatives for Cambodian families like electric stoves. One company, Khmer Green Charcoal, created stoves that run on “clean” charcoal made from coconut shells. More than 6,500 households across the country have made the transition.

  • Boise Is Tapping Into Free, Sustainable Energy - and Other Cities Could Follow Suit

    In the late 1800s a local water company found hot springs in Boise. They decided to build pipes and transport the water to some nearby homes and towns to heat them, creating a geothermal heating system. In the 1980s, the city replicated this model at a larger scale. Water from a naturally hot aquifer flowed through pipes heating 100 large buildings Downtown, equivalent to more than 6 million square feet. Geothermal heating is completely clean, it requires no fossil fuels. Currently, there's only 23 geothermal districts in America. However, one study estimates that by 2050 there could be 17,500.

  • A ski company built a power plant fueled by methane. It's a success, but can it be replicated?

    A ski company and oil and gas executive were able to work out a deal to turn the Elk Creek Mine into a power plant that puts out 24 million kilowatt hours a year and prevents hundreds of billions of methane each year from escaping into the atmosphere. The plant hasn’t made a profit yet for its investors and regulatory red tape could make it difficult to implement in other places, but officials say the plant has been successful and could be a way to combat climate change.

  • Chiredzi-Mwenezi rural communities burn biogas to save trees

    Rural communities in Bandama and Dungwe villages in Chiredzi and Mwenezi are using biogas technology to cook instead of cutting down trees for firewood. The technology relies on fermenting cow dung and using the material in biogas-specific stoves.

  • How to Start (and Run) a Bank That Puts People and Planet Over Profits

    San Francisco-based New Resource Bank was launched with environmental sustainability lending as its niche. But it pursued easier profits for a time, risking its survival and mission until a new CEO turned its fortunes around with a laser focus on the original mission, bolstered by learning its borrowers' businesses intimately. The bank doubled in size and merged with a larger bank, making itself a model for mission-driven lending in such businesses as solar, wind energy, and organic foods – and by attracting institutional depositors and investors as interested in social change as they are in profits.

  • The world's first 'infinite' plastic

    There are several chemical recycling methods being tested throughout the world, including one of the latest ones in the United Kingdom. Mura Technology is building the world’s first commercial-scale plant that can recycle all kinds of plastic and turn them into oil. Their method aims to process 80,000 tonnes of plastic waste every year once the plant opens in 2022. While some criticize that the chemical recycling process is very energy intensive and is not always profitable, the new Mura plant already has partnerships lined up with some plastic manufacturers.

  • Turning oil platforms into reefs

    After oil and gas platforms reach the end of their working lives, some are being turned into artificial reefs that can create new ecosystems in the ocean. Since the 1980s, 550 platforms have been reefed in the Gulf of Mexico and programs are springing up to help industry make the switch. These reefs can be home to fish and birds, and studies have shown that some species prefer these structures over their natural habitats. While not all environmentalists agree with leaving the platforms in the water, scientists are working to understanding how similar programs can be implemented in other parts of the world.

  • Africa's Solar Street Lights Offer Glimmer of Potential

    Solar-powered street lights have replaced the shoddy conventional lighting in Jinja City, Uganda. Solar-powered panels and batteries power lighting that is not only cheaper but is also more reliable and has resulted in social and economic benefits too. Safer streets, higher business revenue for businesses that can operate at night, and a boost in the tourism industry are just a few of the positive outcomes.

  • How to Resolve Community Conflicts

    Community organizing effectively blocked many development projects on O‘ahu that, while involving desirable outcomes like renewable energy, public parks, or affordable housing, failed to consider input from local communities about the potential impact of the developments. Some developers engage local stakeholders early and often in the process, finding that small changes to plans can sometimes avoid conflict altogether. Companies, such as Hawaiian Electric, require community outreach in the first stage of all projects, which has led to the creation of long-term value and positive social impact programs.
