  1. BAU, business-as-usual; ECS, equilibrium climate sensitivity; RE, renewable energy.
  2. Expansion of REs assuming constant geometric growth through 2100, starting from 2013 IEA base values14. The fourth column indicates the year in which total net anthropogenic emissions peak in each scenario, and the final column lists ΔT projections for each scenario for ECS=3.0 °C/2 × CO2.
  3. *2013 basis: wind: 2.30 EJ per year; solar: 1.68 EJ per year; biomass (utility scale): 8.33 EJ per year.
  4. †ECS=3.0 °C/2 × CO2.
