1) Wood pellets are not a “carbon neutral” process as is usually claimed.
2) It can take new trees up to 55 years to offset the carbon released from burning wood pellets.
3) Logging, by disturbing the soil, may result in a much greater release of carbon to the atmosphere, than previously thought.
4) There is no guarantee that new forests will be planted to replace harvested trees.
5) Planting of new forests is happening anyway, and acts as an important carbon sink. To claim this benefit for biomass would be double counting.
6) Trees that die off naturally return the carbon to the soil, and therefore are another carbon sink. Burning this wood instead diminishes this sink, whether new trees are planted or not.
7) Other serious environmental problems are created by the destruction of these forests.
Paul Homewood points out that biomass plants set up between now and 2019 in the UK will receive a guaranteed Strike Price of £105/MWh, at 2012 prices, and indexed linked, for 15 years. The current wholesale price of electricity is about £50/MWh, so clearly the subsidy is the only thing that makes biomass operation economically viable.
