  • Lessons Learned From California's Pioneering Microgrids

    Years after the California Energy Commission funded and launched demonstration microgrids, they’re seeing results. These microgrids, which are localized energy sources that can work independently from large electric grids, were fairly costly, but have shown demonstrable success in lowering utility bills and delivering low-carbon power. As the Commission moves forward with this effort, they hope to continue to learn by doing and improving their processes.

  • Can rice husk briquettes stem the tide of mangrove deforestation in Myanmar?

    Recycled waste from rice mills offers an alternative to mangrove forests as a fuel source. In the Irrawaddy Delta in Myanmar, rice mills are beginning to use their byproducts to create rice-husk briquettes. The logs, made from byproducts previously discarded by rice mills, provide a fuel source for individuals and other businesses that traditionally rely on charcoal. Using recycled rice husks reduces waste and offers a way to alleviate the exploitation of mangrove forests, which act as a vital natural barrier against cyclones.

  • Could Hawaii Be Paradise For Hydrogen-Powered Public Transit?

    Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

  • A climate change solution slowly gains ground

    Three major US companies are leading the way in developing the technology to extract carbon dioxide from the air: Global Thermostat, Carbon Engineering, and Climeworks. With federal tax credits per ton of carbon dioxide captured and a prosperous system of injecting the CO2 back into the ground to stimulate crop yield, the companies' three different approaches all offer a way to cut into the massive amount of global emissions, an opportunity to make a lot of money with new technology, and a helping hand for states working on achieving new federal guidelines and restrictions for a green future.
