As it was said on the Rio-de-Janeiro sustainable development conference in 1992, economy without ecology is a way to a deadlock, and ecology without economy is a way to nowhere. The determining factor in this conflict of tendencies is energy. Economy is impossible without energy consumption for account of both fuels and renewables, and ecology is socio-natural planetary Home that directly depends on the scales of energy production. The author tries to change this contradictory dyad of our life for the triad of energy-ecology-economy of our future perception and validate harmony of the united nature-society-human system.
