We have a smallholding and a few years ago someone tried to sell us a

The idea being that scrubby woodland could be cleared, chipped and the
chippings used to power a 'fed' boiler. We never tried to go forward with
it but the salesman seemed to think that there was various grants and
subsidies that would make it very cheap.

Surely such chippings would be green and would need drying out before you
could burn them?

Be interesting to know how much chipping you'd get per unit of scrubby
woodland - there's not a great amount of wood in typical bushes.
