“A power plant burning wood chips will typically emit one and a half times the carbon dioxide of a plant burning coal and at least three times the carbon dioxide emitted by a power plant burning natural gas.
Although regrowing trees absorb carbon, trees grow slowly, and for some years a regrowing forest absorbs less carbon than if the forest were left unharvested.
Eventually, the new forest grows faster and the carbon it absorbs, plus the reduction in fossil fuels, can pay back the “carbon debt”, but that takes decades to centuries, depending on the forest type and use. We conservatively estimate that using deliberately harvested wood instead of fossil fuels will release at least twice as much carbon dioxide to the air by 2050 per kilowatt hour. Doing so turns a potential reduction in emissions from solar or wind into a large increase.”
Even The Guardian gets it …
