Economics Still early days An example A 100-wind turbine wind farm Complete inspection required Manual inspection: two people per turbine for around a day 200 person days A drone can inspect one turbine in no more than an hour 100 drone hours The drone might identify 15 turbines that need manual inspection 30 person days 10
