| Social-economic development depends on net energy flow Opinion1 #38765 Net energy flow – gross energy (e.g. barrels of oil, or tons of coal) minus the energy invested in extraction, refinement, and transportation – is a critical determinant of an economy/society to sustain and develop itself. |

Citerank: (5) 38769Net energy flow is no longer growing at an exponential rateThe point of inflection at which net energy ceased to be rising exponentially fast and started to decelerate – i.e. the curve transitions from always going up faster in each time increment to going up more slowly in each time increment – may have occurred around 40–50 years ago.959C6EF, 38783Structural change required no longer feasible within time availableThe build-out and scale up of alternative energy capital equipment and supporting infrastructure, to replace fossil fuels in the time remaining before the law of diminishing returns catches up to us, is, for all practical purposes, infeasible.959C6EF, 128075Social-economic development depends on net energy flowNet energy flow – gross energy (e.g. barrels of oil, or tons of coal) minus the energy invested in extraction, refinement, and transportation – is a critical determinant of an economy/society to sustain and develop itself.959C6EF, 128100Net energy flow is no longer growing at an exponential rateThe point of inflection at which net energy ceased to be rising exponentially fast and started to decelerate – i.e. the curve transitions from always going up faster in each time increment to going up more slowly in each time increment – may have occurred around 40–50 years ago.959C6EF, 128191Structural change required no longer feasible within time availableThe build-out and scale up of alternative energy capital equipment and supporting infrastructure, to replace fossil fuels in the time remaining before the law of diminishing returns catches up to us, is, for all practical purposes, infeasible.959C6EF
