Many people have also missed that, when the prices of renewables fall below fossil, renewables start competing amongst themselves. That will produce innovation, and price decreases, that outpace what we have seen thus far.
Wind energy harvest ∝ (rotor length)^2. If u underestimate growth in rotor length --> also underestimate nacelle height (higher = faster wind) --> hugely underestimate in wind harvest for WTGs with marginally higher cost! #wind
