I'm more intetested how much per kW it produces cost, and the maintenance cost over its life span. It has to answer the question is it economical to build and maintain.

This is true, but investing in research and subsidizing its production is how we drive costs down. We’ve done a really incredible job of getting clean energy costs down from where they were, but there’s no need to slow our efforts down now

AFAIK wind hasn't changed much in a long time. Not much to improve really. Cost is materials and labour, both going up. Probably still cheaper then coal.

Can link a video about how they work, and the chalenges tomorow if you want.

Wind has come down a lot, just over a longer time. Solar and storage are what have really plummeted recently. https://ourworldindata.org/grapher/levelized-cost-of-energy

One of the big challenges now in the US is streamlining permitting, for renewables and for transmission upgrades and expansions.

I’d be interested to see the video you mention!

He goes on about the bigger picture, while I was thinking about just manufacturing and maintenance. That graph cost going down could be due to manufacturing ramping up. You need big machines to make big machines.

It's interesting how fast the price per kWh went down. I'm glad.

This could very well. Floating wind is expensive wind, so you could think of this as two turbines for the installation cost of one, or you could think of it as one pylon that produces double the power.
