The rollout of batteries across the global electricity industry more than doubled last year but will need to be six times faster if the world hopes to meet its renewable energy targets, according to the International Energy Agency (IEA).
A report from the global energy watchdog found that new batteries totalling 42 gigawatts (GW) were plugged into electricity systems around the world last year, increasing total capacity by more than 130% from the year before to 85GW.
