There is a way to do this, if you have acreage and water and nutrients.
Plant trees and prune occasionally to promote growth of lower branches.
Once they are big enough, around 6" or so, harvest the branches but leave
the trunk and roots to grow another crop of branches. The roots are the
engine for growth; the trunk just holds up the branches and provides
transport for nutrients. It takes a while, at least 10 years, for the first
crop of branches, but after that you can get sustained yield of fire wood,
given enough producing trees. "Enough" depends on a number of factors. I
don't have the links, but there are sustained forestry sites that explain.
