WoodPellets
WoodPellets is the Nation's LARGEST provider of wood pellets for home heating. We have grown 500% for two years in a row and are continuing at 250% growth. We deliver wood pellets for home heating - nationwide. Wood Pellets are gaining heating-market share immensely as America is mandating clean, renewable, LOCAL energy (and jobs). Congress is pushing legislation and WoodPellets is poised to capitalize off of this trend. GREEN: Wood pellets for heating are CARBON-NEUTRAL. This means that the biomass (trees and plants) eat up as much carbon while alive as they create when burned. Home-heating oil (prevalent in the North East) is laden with pollutants, and like gas -- is not renewable. USA JOBS: Using wood pellets for heat means harvesting, processing, shipping, and utilizing a LOCAL product. Pellets are a low-value and heavy commodity, so they tend to stay in The United States and create regional industries from harvest to flame.
