Wind, solar, and storage could meet 90–100% of America’s electricity needs.
The authors found that with 100% power capacity and no mechanism to store energy, a wind-heavy portfolio is best (about 75% wind, 25% solar) and using large aggregate regions is optimal. It is possible to supply about 75-80% of US electrical needs. If the system were designed with excess capacity (the 150% case), the US could meet about 90% of its needs with wind and solar power.
The use of clean energy to power an entire country (or a group of countries) is achievable. It’s no longer viable to say “we can’t.”
