Roger Pielke Jr explains the Kaya Identity to readers at Foreign Policy magazine, arguing that it is through technology that progress will be made on the global warming problem:
To secure cheap energy alternatives requires innovation -- technological, but also institutional and social. Nuclear power offers the promise of large scale carbon-free energy, but is currently expensive and controversial. Carbon capture from coal and gas, large-scale wind, and solar each offer tantalizing possibilities, but remain technologically immature and expensive, especially when compared to gas. The innovation challenge is enormous, but so is the scale of the problem. A focus on innovation -- not on debates over climate science or a mythical high carbon price -- is where we'll make [progress].
