Global wind farms ran at an average capacity factor of 34% and utility scale solar at 23% based on IEA system analysis assumptions, and those generation realities sit alongside grid investment needs of $3.5 trillion over the decade. Meanwhile, the U.S. installed about 4.0 GW of onshore wind in 2023 and added 8.3 GW of utility scale battery storage, yet industrial power still costs 10.54 cents per kilowatthour on average. Put together with emissions and outage duration figures, these contrasts raise a practical question about how fast grids can adapt.
Key Takeaways
