Looking at 30 yr old windmills to make your case is like looking at the history of the Model T 30 years later to make a case for horse drawn buggies.

It was the beginning of the industry, evidenced by how much bigger the current models are. As your post on the Danish database a week ago (you have to thank the Danes for starting and keeping such data which is the basis for improvements) your have no information on why any of the windmills were decommissioned. Windmills present an engineering problem that companies deal with on a constant basis - wear of bearings, loads on shafts, effects of the environment on the blades, all kinds of problems that are dealt with innovation and improvements in parts.

Additionally, an issue that is unknown - did the windmills decommissioned break even and make money? Did they produce enough electricity to pay for the cost to produce, install and operate? It seems that your post assumes that they did not.

Again the #1 reason windmills are suited mainly to utility scale windfarms is that as the swept diameter of the blades double their output is cubed. It would be also the reason to replace a functional smaller one with one many times the output thus a strong economic reason for the replacement, not as your post implies due to being worn out.

Wind and solar are being implemented every year in greater amounts than any other form of energy producer. And every volt being used reduces the amount from coal, natgas and nuclear making those plants less economical. Batteries and long distance transmission lines also help get power from where it's abundant to where it's needed.

Wind and solar also share a principle advantage - they don't have to deal with energy manipulators for their fuel.
