As we slowly wean ourselves away from our centuries-long love affair with fossil fuels in an attempt to reduce CO2 emissions and combat global warming, there has been a rapid expansion across a broad range of clean energy technologies. Whether it’s a set of solar panels on your roof, a wind farm stretching across the horizon, or even a nuclear plant, it’s clear that we’ll be seeing more green power installations springing up.
One of the green power options is biomass, the burning of waste plant matter as a fuel to generate power. It releases CO2 into the atmosphere, but its carbon neutral green credentials come from that CO2 being re-absorbed by new plants being grown. It’s an attractive idea in infrastructure terms, because existing coal-fired plants can be converted to the new fuel. Where this is being written in the UK we have a particularly large plant doing this, when I toured Drax power station as a spotty young engineering student in the early 1990s it was our largest coal plant; now it runs on imported wood pellets.

The coal-to-wood story has a very rosy swords-into-ploughshares spin to it, but sadly all isn’t as well as it seems with wood biomass power generation. Nature has a feature expressing concerns about it, both over its effect on the areas ..
