GE installs world’s first spiral-welded wind turbine tower
The strongest winds tend to be higher up, but as this 2022 study shows, higher-mounted turbines catching stronger wind doesn't necessarily equate to the lowest cost of energy. Indeed, once you factor in the costs of stronger foundations and taller, sturdier towers, anything above about 120 m (394 ft) tends to result in more expensive electricity – and in a market as price-sensitive as energy, that's bad news. Somewhere around half the Levelized Cost of Energy (LCoE) in an average commercial wind energy installation comes…
