" Wood-burning power plants would require cutting trees and burning them, which emits just as much CO2 per kWh as coal. This may have an immediate adverse global warming impact. Moreover, burning wood emits at least as much airborne health-damaging particulates as burning coal. Wood-burning proponents and governments claim that burning wood is “CO2-neutral.” They purposely forget to add, “over a period of about 100 years.” Global warming is a problem now. Forests from which wood is taken would require about 100 years to recover from the damage, based on numerous studies. Wood-burning power plants are an inappropriate 100-year “solution.”
