What is an example of generating energy through combustion of renewable bio fuels that cause minimal harm to the environment?

An example of generating energy through the combustion of renewable biofuels is using wood pellets made from sustainably sourced sawdust and wood shavings in biomass boilers. This process produces energy with a much lower carbon footprint than fossil fuels, as the carbon dioxide released during combustion is approximately equal to the amount absorbed by the trees during their growth. When managed responsibly, such as through reforestation and sustainable forestry practices, this method causes minimal harm to the environment compared to traditional fossil fuel sources.
