  • Climate change: 'Sand battery' could solve green energy's big problem

    A team of Finnish engineers havevinstalled the first commercial battery made of sand, which can store green energy in it for months. Solar panels or wind turbines generate electricity, which is then stored as heat in the sand battery. When needed, the battery can discharge hot air to heat up water which is then used to heat homes, offices, and a swimming pool. This solution may be difficult to scale, but it’s a low-cost storage idea that could be useful when it’s cold and energy is more expensive.

  • How to recycle the unrecyclable

    A chemical recycling plant in Germany is taking old tires and turning them back into their original components. From there, those materials can be used in the production of insulation, steel, and oil. The gas that is discharged during the process is also used to power the whole plant. Other plants around the world are also exploring how to take plastic waste and chemically recycle it instead of burning it, so there are less carbon emissions.

  • Building a just energy business future in Detroit

    WeSolar makes solar power accessible to low-income residents by building and investing in community-solar farms and signing residents up for credits from investor-owned utilities. The startup, the first community solar business led by a Black woman, saves customers as much as $250 on their utility bills by signing up for community solar. Convincing residents, many of whom have had bad experiences with predatory utility schemes, requires working with church and community groups to earn trust. Community solar also requires legislation that allows for shared renewable energy projects.

  • Virginia project helps low-income homeowners ditch fossil fuels

    Two organizations partnered to help eight low-income households convert their homes to become all-electric in Virginia. It entailed replacing fossil-fuel based heating and cooling systems like stoves and water coolers with electric ones. Some of the households saw a reduction in their utility bills. Organizers estimate that over the course of 20 years the changes will result in the households avoiding the emission of over 2 million pounds of carbon dioxide.
