Instead of wasting the already wasteful energy by making fertilizer out of air, these farms could likely much more efficiently re–capture runoff from their waterways that is now being dumped into the sea harming humans and wildlife alike.
I think this has been greatly exaggerated, but even if the claims are true it's as nothing compared to fossil fuel.
People get all emotional about views, but most people find it beautiful and a few people's visual aesthetics should not override one of the pillars of the future economy.
Additionally, the fix for runoff from farms into the gulf is mere regulation and fining, but that's not going to stop the need for ammonia! Plus, try to regulate these farmers, they are largely parasites in the country through the farm bill yet still remain one of the most potent political factions in the country.
And even if wind wasn't wasteful at the outlet, you're still using it to turn air nitrogen into the same compounds that you are dumping into the seas, lakes and drinking water.
I have not reviewed every method but, even if they are energy intensive, they probably beat blasting a carburetor and dumping the compounds.
