Surveying the available alternative energy sources for criteria such as energy density, environmental impacts, reliance on depleting raw materials, intermittency versus constancy of supply, and the percentage of energy returned on the energy invested in energy production, none currently appears capable of perpetuating this kind of society.
The climate change debate is basically not about science; it is about ideology. It is not about global temperature; it is about the concept of human society. It is not about nature or scientific ecology; it is about environmentalism, about one - recently born - dirigistic and collectivistic ideology, which goes against freedom and free markets.
