Generally speaking, at a community level we can look at very small-scale residential or we can look at a medium or large scale, in institutions and commercially.
Generally with biomass, there are two options: You use either chips or pellets. If you talk to the operators of the boiler systems, chips are less expensive, but it takes more technical know-how to manage and more space to store the fuel; also, it's dirty and so on.
Wood pellets are very homogeneous. They're dry, compact and easy to store. For smaller scale, particularly in Atlantic Canada, where there isn't much natural gas distribution, we found the use of boilers in those kinds of systems very beneficial. You install the boiler, and it is very easy to operate, and at low cost.
I'm not sure I can add much more than that.
