As the need for a clean fuel source grows, researchers have turned to small pellets of compressed wood. They are harvested from pine and hardwood tree forests in the South American South. After being collected they are dried, compressed, and converted into pellets that are as long as an inch. They are combusted as fuel in electric power plants, mainly in the United Kingdom and Europe, to supply power to homes and businesses.
But the biggest debate is whether they are really a clean source of fuel. According to the norms patronized under the Paris Climate Agreement and reinstated this summer by European regulators, burning trees for power generation falls under a carbon-neutral energy source category if the trees are replaced by planting by newer ones. The wood pellet industry claims that it is a better alternative to coal and a sustainable resource. Every pellet is replaced by a tree, which will reduce the carbon content in the atmosphere.
There are many contradictions to it as well. A professor from MIT Sloan School of Business John Sterman, we are putting carbon into the air currently, but regrowth takes time. And the yield is not determined and is. The carbon may be removed in decades or even centuries. A $1.2 trillion infrastructure bill is in the works as signed by the president of USA Joe Biden, but more research is required to state solid-grounded facts about its sustainability.
