Pumped Hydro is a nice stopgap to help storage keep up with wind and solar. Batteries are still only a small percentage of our production numbers. We are still only just about 6GW which is about 0.2% of average totals. Current projections are showing about 860GW by 2030 which is about 25% of current average production. However production will need to increase significantly to offset current fossil fuel emissions.
We are reaching the point where solar and wind are so insanely cheap that it's raining soup. Everyone is scrambling to find a bigger bucket.
