Smart energy sources like coal, nuclear, hydroelectric and natural gas, exist because they satisfy a permanent demand for cheap and reliable energy. Dumb energy sources exist because government has put its thumb on the scale in the form of subsidies and mandates. Dumb energy will cause disastrous collapse of the modern world, even walk-in conquests by enemies.
