“Alluringly misleading” is the implication that “the planet” can live today without bridge fuels and provide adequate amounts of energy from “renewable non carbon-based” sources. In the first place, all known technologies which don’t burn fuel of some sort have adverse environmental impacts unique to each. Secondly, an all-out effort to deploy these technologies today would cause real hardship everywhere as we tried to live without adequate transportation, space heating, electrical appliances, etc.
