Steven Hayward:
Cost, scale, and density are the three main points of any good energy analysis (I call these the “Energy Triumvirate”), and is what I drill students about from the first day of class to the last day of class. A lot of current energy enthusiasms, like solar and wind power—not to mention batteries for cars and the grid—are hugely resource intensive, which makes their tradeoffs over fossil fuels far from a slam dunk, as we have mentioned here many times in the past.
