Parkinson's law corollary
The energy consumption debate is a typical example of Parkinson's law. In a corollary: "Electricity use expands to the amount alternatives are added to the mix.".
With this in mind, you do not get better at generating environmentally friendly, but are simply continually expanding and using more resources. It is insane, but we humans are absolutely terrible at being satisfied with less. It is extremely difficult for humans to be happy with fewer things. We keep expanding, which is exactly what Parkinson observed and described.
