Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Efficiency scales badly -the first steps are often massively profitable, then zero cost, then increasingly more expensive, and subject to jevrons paradox in any case -

This does not hold true for just wholesale switching energy input into the economy. Building a hundred x - reactors, windmills, dams, whatever -is cheaper on a unit basis than building ten. So as long as the underlying resource is sufficient, no problems.
