Pellets are green mostly in relation to how close to the plant you live......
Even if trees were grown from scratch, it is still basically solar energy converted to stored fuel - MINUS the energy used to make them. But most pellet plants use the same wood to burn and dry the pellets. Some are planning to install wood or pellet burning electric generators at the plants for the massive amounts of electric required to run the pellet presses, the coolers, the hammermills, etc....
Still, consider electricity from your normal grid - it is estimated that 50% of the energy is lost in transmission. More is lost in generation and transportation of coal and other fuels to the plant.....
There is no perfect fuel, but wood from any renewable and sustainable source which is located close to the end user - is one pretty good way to supplement our energy needs.
