Some coal plants add wood to cut emissions

New York Times : In anticipation of new regulations on carbon dioxide emissions, some coal-fired power plants in the US are starting to add wood to the fuel mix. Wood is considered carbon neutral, because the carbon released when it’s burned was originally appropriated from the atmosphere and incorporated into the growing tree. In addition, rather than chop down growing trees, power plants are using wood scraps from paper mills, furniture factories, and logging operations. There are drawbacks, however: Not all coal plants can be altered to burn wood, wood may not be readily available in certain areas, wood burning is less efficient than coal burning, and wood is perishable—it can rot or grow fungus. However, until carbon capture techniques are perfected, some plants may add wood burning as an interim measure to meet new Environmental Protection Agency requirements.
