Clear explanation of #jevons, and why #efficiency and #technofix make things worse

Taking this global perspective with respect to the economy, efficiency gains will do the exact opposite of what efficiency policy advocates claim it will do. If technological changes allow global energy productivity or energy efficiency to increase, then civilization will grow faster into the resources that sustain it. This grows the economy, but it also means that energy consumption and CO2 emissions accelerate.

CO2 emissions can be stabilized despite efficiency gains. But this is possible only if decarbonization occurs as quickly as energy consumption grows. At today’s consumption growth rates, this would require roughly one new nuclear power plant, or equivalent in renewables, to be deployed each day.
