Why the low carbon transition may be much cheaper than models predict
To achieve net-zero emissions by mid-century, global energy systems must undergo a wholesale switch to low-carbon and energy-efficient technologies. However, many models used to chart this transition imply that there are benefits in delaying investment in these technologies, waiting instead for R&D to drive down costs over time. Such models overlook findings from a vast literature showing that the costs of these technologies decline as a result of their use. Our new paper in Environmental Research Letters draws on evidence from more than 200 journal articles and concludes that policies promot...
