A new biomass plant under construction in Georgia highlights the challenging economics of the technology, even in a state so rich in forestry waste it exports it to other countries.
The 50 MW Albany Green plant – the largest renewable energy project in the state so far – is a unique collaboration among Georgia Power, private companies (including Procter & Gamble) and a nearby Marine base. While the cost for biomass generated electricity is too high to compete with wind and solar, the project also produces steam for industrial use, which improves its economics.

The idea that to generate electricity should be considered climate-friendly has been debated by scientists and politicians for years. Advocates, including many scientists, ask what could be more sustainable than burning trees? They drink in planet-warming gasses while growing, and give it back up when they are burned — a perfect closed loop with no net emissions. Critics, on the other hand — including other researchers — say the science is much more complicated than all that, and that when managed poorly, woody biomass power could be worse for the climate than coal.

The use of U.S.-produced wood pellet fuel blended with coal in large utility power stations could sustain coal mining jobs, create tens of thousands of new jobs in another sector that is experiencing significant job losses—the forest products sector—and stimulate billions of dollars of new investment in new U.S. manufacturing plants.
By supporting the blending of industrial wood pellet fuel with coal in pulverized coal (PC) power plants, policy will lock in the need for PC power plants, therefore guaranteeing significant demand for coal. This well-proven strategy, which is already in place in many other countries, can provide certainty for the need for U.S.-produced coal for decades, and certainty for U.S. coal mining jobs.
