  • 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.

  • 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.

  • How rechargeable tricycles are saving pregnant mothers and newborns in rural Zimbabwe

    Mobility for Africa provides electric tricycles, called Hambas, to take pregnant women to and from health appointments. Mobility is critical to reduce maternal and neonatal mortality and the three-wheel tricycles are easy to drive on rural roads. They run on a lithium battery that can be charged in about six hours using renewable energy and a single charge gets about three trips. The transportation allows women who live far from clinics and cannot afford transportation be able to access medical care. About 50 Hambas currently take women to and from doctor appointments during pregnancy until after delivery.
