Greenhouse and Nursery - Alternative Energy Sources for Heating

There is increased interest in alternative energy sources for heating greenhouses and heated nursery facilties. The following are some of the possibilities:
  • Burning biomass grass crops such as switchgrass and miscanthus
  • Burning biomass wood crops such as hybrid poplar, willow, and other quick growing species
  • Burning recycled wood from construction, demolition, pallets, etc.
  • Burning corn and other grains (high price currently)
  • Burning spent oils, recycled oil, spent vegetable oils
  • Burning biogas from digested organic materials such as manures (methane)
  • Heat recovery from commercial composting
  • Solar hot water accumulators

I will be writing more about these and other options in the future.
