Will the Billionaire Taxes Cause the Rich to Go Elsewhere?

Published

on

One of the most common arguments against taxing the rich is that they will simply leave whatever area is levying the tax.

We hear about this most often in connection with New York City, where its liberal mayor using the taxes he’s raising the build infrastructure, feed hungry people, etc.

Here’s what’s happened in Massachusetts.

Some Investments Are Bound to Fail–But Only Time Will Tell Us Which Ones

Published

on

A common tactic of Big Oil and the rest of the Trump-supporting world is to point out that some of our government’s investments in cleantech do not pan out.

Unscrupulous people, as well as tens of millions of idiots, are enraged by these failures and interpret them as evidence of incompetence and/or corruption.

On the other hand, fair-minded people understand that it’s impossible for all these investments to be winners; some are bound to fail as the advancement of technology makes unforeseeable twists are turns.

The plummeting costs of solar PV and wind over the past 10 years wiped out a great number of investors in both the private and public sectors, and solar thermal (shown here) was only one.

As an example, I used to attend the annual conferences on hydrokinetics, and I always looked forward to them.  Guess what?  They’re gone. They no longer exist, as a result of the fact that the LCOE (levelized cost of energy) of all forms of hydro can’t compete on large-scale projects, and thus have been relegated to small, niche applications.

Allen Hall 2025: Good morning, everyone. The world is racing at the minute, and let’s start with the biggest race of all. NextEra Energy, the largest utility in America by market value, is in talks to buy Dominion Energy of Virginia. The price? It’s about $76 a share, roughly $66 billion. With debt, the combined company would be valued at about $400 billion.

That would make it the largest power deal on record. A mostly stock transaction, at least that’s what’s being reported, and a deal could come as soon as this week. Pretty shocking. Now, why does this matter to wind? NextEra is [00:01:00] not just a utility. It is one of the largest renewable energy developers on the planet.

And Dominion sits on top of Northern Virginia’s data center alley, the biggest concentration of data centers in the country. Dominion expects its peak demand to double by the end of the twenty-thirties, American power consumption hit a second straight record in twenty-twenty-five, and it’s still climbing. So the company that builds more wind and solar than almost anyone wants to merge with the company that serves the hungriest grid in America. That is a race to the top. But down on the ground, developers are running a very different kind of race.

Wind projects under construction in the United States are up 60% since the start of twenty-twenty-five. Solar is up about 50%. Why the surge? Well, the clock is ticking. Tax credits for wind and solar were gutted in the one big beautiful bill. Projects must begin construction by July 4th [00:02:00] and prove they are building continuously to qualify.

Under the Inflation Reduction Act, those credits were supposed to phase out at the end of twenty-thirty-three. Now that deadline is just a couple of weeks away. Developers are pushing hard on projects that can make it and abandoning the ones that cannot. One solar executive put it plainly: “A lot of the projects are going to die on the vine.”

And that’s a real shame. Labor is short. Of course, electricians are in demand. Transformer lead times have stretched to 18 months because data centers are buying them too. Even permits are hard to get. Projects that touch federal land, of course, that once took a month to approve are now waiting up to a year.

So while NextEra races to buy the grid, developers are racing to build before the door shuts. Now, across the Atlantic, there’s a different kind of race going on. Chinese turbine manufacturer MingYang [00:03:00] Smart Energy is looking for a new home, and quick. Back in March, Britain blocked the company’s plans for a one-and-a-half billion pound factory in Scotland, mostly based on security grounds.

MingYang’s European chief, Horatio Evers, says the company is now talking to Spain and scouting other locations on the continent. He says MingYang wants to build turbines in Europe with a European workforce. And this is the part I don’t understand, ’cause European workforce tend to be more expensive.

However, uh, MingYang wants to build that factory, but there’s a condition. They need a guarantee that their turbines will be allowed into the market, and so far that hasn’t happened. The European Commission launched a review of Chinese manufacturers back in 2024. Those findings are still unpublished. So MingYang is racing to find a country willing to say “Yes.”

Further east, Turkey is entering the offshore wind [00:04:00] race for the first time. The government has defined four areas along its western coast, all on the Aegean, for its first ever offshore wind tender. Turkey’s energy minister says Turkey aims for five gigawatts of offshore wind by 2035.

The country has committed $30 billion to transmission infrastructure. And Turkey already has 15 gigawatts of onshore wind spinning today. Turkey is, of course, a NATO ally, and it straddles Europe and Asia, and now it’s stepping into offshore wind. And finally, up in the North Sea, off the coast of Norfolk, England, 75 miles from shore, Cadeler of Copenhagen just installed the first monopile foundation at Hornsea 3.

When complete, Hornsea 3 will be the single largest offshore wind farm on the planet. 2.9 gigawatts, 197 foundations, enough power for 3.3 [00:05:00] million British homes. The project is owned by Danish giant Ørsted and will bring 5,000 construction jobs to the region. Hornsea 1 and 2 are already spinning, and of course, Hornsea 4 is on the drawing board.

So here’s the picture. America’s two biggest utilities are racing toward a $400 billion merger. Developers are sprinting to break ground before the Fourth of July. A Chinese turbine maker is searching Europe for a factory, and Turkey is marking out its first offshore wind zones. And over in Britain, they just planted the first foundation at the world’s largest wind farm.

Everyone is racing. The only question is, who gets there first? And that’s the state of the wind industry for the 18th of May, 2026. Join us tomorrow for the Uptime Wind Energy podcast
