SunZia, as it’s called, will be the country’s last landmark wind project for some time. After this year, annual onshore wind power additions are forecast to decline until 2030, according to BloombergNEF.The biggest reason is President Donald Trump’s assault on renewable energy, and wind in particular. He has vowed to block new wind development in his second term. But Trump isn’t the only culprit: inflation, supply challenges and local opposition have complicated development since the Biden administration. The wind industry also has to contend with the end of lucrative tax credits this year, tariffs and long waits to connect to power grids.
