Estimation of global final-stage energy-return-on-investment for fossil fuels with comparison to renewable energy sources
Under many scenarios, fossil fuels are projected to remain the dominant energy source until
at least 2050. However, harder-to-reach fossil fuels require more energy to extract and …
