Trump said. “They ruin the environment, they kill the birds, they kill the whales.”

So it's not dogs and cats this time. Ok.

Investors are interested in projects that start making money quickly, and wind is pretty good at that over other power infrastructure. Trump is going to be fighting the free markets that he holds so dear.

Trump does not hold the free markets dear. He holds only himself dear.

In Nantucket, shards of fiberglass covered the coast for miles after a blade exploded on an offshore windmill, leading to widespread ecological damage. Admittedly it isn't a common event, but it does show the capacity for pollution from wind turbines:

The effects on the lifecycle of offshore wind on aquatic life including whales is a subject of ongoing research:

It's known that there's a major impact of wind turbines in general on birds, confirmed by several studies:

https://abcbirds.org/blog21/wind-turbine-mortality/

There is also a risk from operational fluids within the wind turbines, and part of the ongoing risk analysis of one wind farm was a scenario where 20,000 litres of dielectric fluid were released into the ocean:

https://response.restoration.noaa.gov/offshore-wind-spill-exercise-held-northeast-region

The nature of the ocean is such that there's a potential to pollute a large amount of water and coastline, making the risks unique to offshore wind, where they would be much more localized in an onshore wind farm.

That being said, it is fair to point out that all forms of industrial scale electricity generation, no matter how "green", will have a potential environmental impact simply by the nature of how massive such operations need to be, so the question is always about finding the least bad option rather than pretending there's any one option that is perfectly positive for the environment.

To be honest though, offshore wind projects don't make any sense in a free market. The cost per MW is significantly higher than the market can support, so the only way to have these things is to take money from someone else to pay the difference. For example, the average wholesale price of electricity in America in 2024 was between 30 and 60 dollars per Megawatt. The cost of offshore electricity is closer to 200 dollars per megawatt. The difference is made up with government grants (which aren't free market) or by power companies charging customers using other forms of electricity more to cover the difference (which is only happening due to regulations and so isn't really a free market mechanism)

This has occurred elsewhere too. In Ontario, many people applauded the massive increase in solar generation, but the price was that the electrical companies paid over 80 cents per kilowatt hour for electricity they then sold at wholesale for closer to 4 cents per kilowatt hour. The difference was paid for by a "global adjustment charge" which massively increased first retail consumers electric bills, and later when that was rescinded somewhat could as much as double the bills of industrial consumers and led to "global adjustment days" where industrial plants totally shut down for a day to avoid the charge.

An example of green energy that could win in the free market running up against government would be hydroelectric. Some of the least expensive electricity in the first world such as Manitoba and Quebec Canada and Norway in Europe, comes from hydroelectric, and unlike solar or wind it can be created at a scale large enough to power an entire region. Moreover, it can be used as a base load which neither wind nor solar can. In many regions where it's practical, lobbyists have ensured that spots that could have good hydroelectric are not allowed to be used for that purpose. There isn't much money in successfully providing cheap power to millions of people.

I'm just so amazed that science can say one thing, based off decades of research, knowledge and investigation a d measurements... And asshats like trump can just yell absolute disproven nonsense and people just run with that because scientists are evil, and what does science knows? With every discovery they completely change their minds!

I'm so so tired

Sounds pretty anti business to me, regulations are looking this country haven't you heard?

The wind developers are private companies that have already spent hundreds of millions of dollars purchasing the leasing rights to the wind energy areas and associated costs.

The parts of the projects under federal control are a) reviewing the proposed leasing areas and projects, b) putting the leasing areas up for auction, c) reviewing the environmental impacts, and d) ensuring the developers remain in environmental compliance throughout construction and operation. That's all the federal government can control, and other than that the private business can do what it wants. A, b, and c has pretty much already happened on a huge swath of all wind energy areas, and the only thing he be able to stop now is compliance of already leased areas and leasing additional areas.

That means if he stops up from maintaining compliance, the developers will have no reason (other than personal moral compass) to not harm the environment (including harming severely endangered right whales) and not report it. He can't stop the current projects from happening, at least not without huge legal battles costing the federal government a massive amount of money to pay back the developers. Not to mention the tens of thousands of jobs he'd be costing of he put them out of work when they've already been contracted for years at a time.
