I agree that altering weather patterns is a potential consequence of using wind turbines, but it is likely to be a modest one. Even as densely packed as you can put them, wind turbines only use up a portion of the kinetic energy embodied in low-altitude wind. Compared to the total energy in a weather front, it is definitely small potatoes.

That being said, complex dynamic systems like weather can respond in non-linear ways to inputs, so it is definitely worth investigating what second-order effects might result from much larger scale wind deployment.

Some of the more active current users (Texas, Germany) might be able to provide preliminary data for examination.

I doubt that hydrogen fuel cells will ever be a widely used technology. Basically, this is because hydrogen is an inferior fuel that is always made from better ones (electricity or hydrocarbons). There are also lots of cost and practicality issues:

I guess what I’m trying to understand is whether that change is inconsequential or truly detrimental.

I’m no scientist, either, but I know if you throw a pebble in the pond, the pond might look the same but it is forever changed.

Same probably holds true for wind power.
