When I was a kid, Mum did the washing in a copper of boiling water over an open fire in the back yard. We collected the wood from the back paddock with a horse and dray. It was all very “green” (but we thought it was just hard yakka). Greens want us to return to this primitive method for generating heat, and even electricity.
It is sensible for industrial plants such as sugar mills to burn readily available organic waste such as bagasse to generate power. But to deliberately build power stations to run on wood chips is a step back to the BC (before coal) era when forests were clear-felled to produce fuel and charcoal to feed boilers and furnaces.
Coal is an energy-dense fuel, and often has huge deposits in a concentrated area. Long-life power stations can be built close to the coal deposits, thus minimising transport costs and land disturbance.
Wood, however, has very low energy density and biomass energy is always spread over large areas of land. The fuel gathering operation must move every day, with enormous waste of transport energy and displacement of plants and animals.
