My wife was traveling westbound on US-30 the other day and witnessed this giant wind turbine blade at the intersection with US-421. Impressive!
We are truly living through the 3rd industrial revolution (as explained in this video).
I saw the early stages of commercial wind farms in northern Iowa, near my parents’ childhood home. It was erected in 2002. The turbines seemed enormous at the time. They stood 65 meters tall (at the central hub) and produced a maximum 0.676 MW of power.
Off-shore wind turbines (larger than the on-shore variants, and comparatively new) are now reaching even 13.0 MW, producing nearly 20 times the peak power of those 2002 versions (which I believe are being or have been decommissioned). The center hub stands 141 meters above the water. A single spin of this new wind turbine could power a home in the UK for two days!
