If there’s one thing Georgia has a ton of — actually a billion tons — it’s trees. The state leads the country in acres of private timberland and volume of timber harvested. Some in the timber industry think we should turn more of that wood into electricity.
From several stories up at Exelon’s Albany Green Energy plant, you can see a massive pile of chipped up wood, known as biomass. A long conveyor carries it up into the plant, where it’s fed into a boiler.
The biomass burns to make electricity for Georgia Power. Around the corner from the wood pile, a long tube snakes off, carrying leftover steam to power a Proctor and Gamble plant.
From the top of the power plant, you can also see trees: miles and miles of forest in every direction.
But, “we’re not just going out and grabbing a tree, being able to use that tree,” said plant manager James Luckey. “Most of our fuel is coming from treetops, and mill residuals that come from paper mills or something like that.”
They burn the stuff that can’t be made into lumber or paper products. Advocates in the timber industry say there’s plenty of wood waste like that in Georgia that could be made into power.
Johnny Bembry owns a tree farm in Pulaski County. He ends up with waste when he thins his trees to prevent fires and disease.
“That waste from the thinning, it’s going to have to be burned,” Bembry said. “It’s either going to be burned in the woods and wasted, and release carbon in that manner, or it could be burned for energy creation.”
The Georgia Forestry Association, an industry group, is calling for more power plants around the state that burn biomass. They say it’s a good use for leftover wood, cleaner than coal, and renewable because you can keep growing trees.
“They’re talking about sustainability in terms of, ‘well, we replant,’” said Vicki Weeks of the Dogwood Alliance, which opposes biomass power. “We’re talking about, we can’t afford to lose 40 to 50 years in terms of CO2 uptake.”
