Is planting trees more effective than growing biofuels?
The EPA estimates that growing a Douglas Fir forest for about a century is 25% to 50% more efficient at reducing carbon dioxide buildup than using an equivalent amount of land to grow biofuels. In other words, if you grow switch grass hay to produce electricity you will allow roughly 25% to 50% more carbon dioxide to remain in the atmosphere than if you had planted a forest of Douglas Firs on the same amount of acreage and used coal to make electricity.
