    1. Although “renewable energy promoters claim that we can replace our current energy needs without fossil fuels,” adds Berman, the truth is this: “The triumph of technology may allow that but it will do little to end the ongoing ecosystem disaster.”

      There are researchers looking at the amount of fossil fuel energy required for the transition. One research group is MIT: https://climate.mit.edu/ask-mit/does-concrete-needed-build-renewable-energy-negate-good

      Other researchers have estimated fossil fuel budgets that need to be reserved for building the initial renewable energy production infrastructure for the transition.

      Research is nonlinear. A recent breakthrough might circularize cement industry:

      ‘If Cambridge Electric Cement lives up to the promise it has shown in early laboratory trials, it could be a turning point in the journey to a safe future climate. Combining steel and cement recycling in a single process powered by renewable electricity, this could secure the supply of the basic materials of construction to support the infrastructure of a zero emissions world and to enable economic development where it is most needed.’ http://www.eng.cam.ac.uk/news/cambridge-engineers-invent-world-s-first-zero-emissions-cement
