I mean.. coal is bio-energy. Oil is bio-energy. The remnants of bio-mass that never made it to the sky, but whose carbon dioxide instead was stored in the ground by nature herself, process commonly known as "natural sinks". How can it be healthier for the planet to burn off bio-mass before it even gets a chance to sink or be "filtered" through various other life forms? I would have thought the production of bio-mass in sum cause as bad outlets of CO2 as oil. Not to mention the harm it does to various species, humans included, when huge areas of diverse vegatation is sacrifized to grow a single type of "fuel base" plants.
