Part 3/8:
The key innovation: Compressed Air Energy Storage (CAES). During periods of low demand or high wind power, electricity would be used to pump air into these giant cavities, creating a form of stored energy. When demand rises, the compressed air would be released to spin turbines, generating electricity for California and beyond. The entire setup involves high-voltage lines stretching some 10 miles from Utah to processing stations, illustrating the scale and complexity of this clean energy solution.
