Burning is necessary, as you say, to manage forests. But it can’t be relied upon as a means of energy production. Not sustainable, as greenies love to say.
Biomass will never be “zero-carbon” emissions as it requires lots of diesel fuel to harvest, prepare, and transport it.
There is a clear alternative that is the best for the environment - cleanest, cheapest, and most efficient.
Nuclear power. Nuclear power is the option that most rational and thoughtful environmentalist are starting to look at again and that is a good thing.
Nuclear power can answer our electricity problem. Nuclear power can answer our “water shortage” problem as well with desalinization. Nuclear power is the future for the “greens” if they examine the problem objectively, but that is the rub.... I don’t think they are objective as most of them will easily come around to the “there are too many people” argument.
