The power plant on our campus is set up so that it can burn either coal, natural gas or wood feed stocks. At the present time the natural gas lines are blocked, since the trends of increasing price made it uneconomic to use within the boilers. However the plant uses around wood for 40% of the feed, and has for a number of years. It helps, both with pollution control, and with the overall plant economics (oftimes being cheaper per kwh generated). We are located adjacent to a national forest and thus there is a ready supply of material.
