This reminds me of a fun fact: the green energy infrastructure of tomorrow will be built on the brown energy of today. How much would it cost to build a wind farm, hauling 150' blades and 60-ton nacelles, using battery-electric trucks? And what if the electricity to charge those trucks came from coal extracted using battery-electric mining equipment and delivered by electrified heavy rail?
