The Bigfoot Hybrid Willow can also be used for its wood. It can be used for firewood, mulch, lumber, pulp, and as a biomass crop.
As a fast-growing firewood crop, it will be able to create more BTUs per an acre in a shorter time frame than most other trees. This will give you a readily supply of wood to burn. The negative is that individually as firewood, it is fast-burning and low in BTUs. I would suggest if you made a firewood plantation for your winter heating needs, that you use something like the Bigfoot Hybrid Willow along with black locust, which burns longer.
As a biomass crop, these fast growing trees will become more popular as more and more acres are converted into permanent energy crops. Lumber and pulp are a couple other products that these hybrid willow trees can create. Lumber would have similar properties of other willow, so it would have some use for special applications.
