Περιγραφή βίντεο:

This free, downloadable B-roll footage from the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) is for use by news media and education organizations. This high-resolution video features clips of GreenWood Tree Farm in Boardman, Oregon, including shots of a biomass harvester harvesting 3-year old poplar trees for biofuel, a close-up of harvested poplar trees, mature rapid-growth poplar trees, and planting new growth (poplar trees and saplings) for biofuel.
