  • Following the fuel: How portable biomass energy generation may help rural communities

    The forests that surround many of California’s mountain communities tend to have an abundance of woody biomass and a pressing need for thinning to reduce fire danger. Revenue from selling forest residues to biomass power plants could help to support fuel reduction activities, but in many cases the nearest plant is so far away that hauling costs are prohibitive. The remoteness of such ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...
