More batteries.

Battery costs have fallen by more than 90% in the last 15 years, and in 2023, battery deployment in global power systems more than doubled, according to a report from the International Energy Agency.

The real kicker to me from this IEA report is that for the world to meet its 2030 climate goals, energy storage capacity has to increase sixfold, IEA says, and battery storage needs to be 90% of that.
