History

Historical Context

Amazon's 2017 purchase of 90% of the 253-MW Texas wind farm built by Lincoln Clean Energy (now Ørsted) marked an early corporate clean-energy deal; the U.S. wind fleet then exceeded 100,125 MW in 2019 (?7 % of electricity) and global wind capacity grew 13 % annually through 2023, paving the way for today’s large-scale power purchase agreements that reshape the energy market.
