The researchers are amazingly confident.
"Our main contribution in this paper is to systematically apply this method, which we call the stochastic experience curve or stochastic Wright’s law to the energy transition."
"for several decades the costs of solar photo-voltaics (PV), wind, and batteries have dropped (roughly) exponentially at a rate near 10% per year"
"Is there a path forward that can get us to netzero emissions cheaply and quickly?," our answer is: "Very likely, and the savings are probably quite large."
