These huge new wind turbines are a marvel. They’re also the future.

Add all that up and, at a “typical German North Sea site,” GE says, each Haliade-X will produce about 67GWh annually, “enough clean power for up to 16,000 households per turbine, and up to 1 million European households in a 750 MW windfarm configuration.” (Suffice to say, the number would be smaller for energy-profligate American households.) That’s “45 percent more energy than any other offshore wind turbine available today,” according to the company.
