By 2023, the global energy storage market was forecast to reach $42.9 billion, yet grid limits still forced 58% of electricity from variable renewables to be curtailed in a 2016 study. At the same time, lithium ion battery pack prices averaged $132 per kWh in 2023, while 1.3 billion people still lack electricity access worldwide. Efa statistics tie these tensions together, showing how investment, technology costs, and grid realities collide and shape what scales next.
Key Takeaways
- 1.7% of global electricity was generated from wind in 2012 (as a reference point for wind power growth drivers)

- $253 per kilowatt ($/kW) median turnkey cost for utility-scale PV was reported for 2021 in the benchmark report
- $1,100 per kilowatt-hour (kWh) median pack cost for lithium-ion batteries was reported for 2021 (technology cost benchmark)
- 1.6% lower cost of energy (LCOE) per decade is expected for onshore wind through 2030 in IRENA’s outlook (efficiency improvement metric)
- 9.2 months median interconnection process duration for a specific US program (queue timing metric)
- 98.5% power quality compliance rate was reported for a utility-scale distributed generation pilot (reliability metric)
- 0.8% improved capacity factor from advanced inverter controls was reported in a peer-reviewed wind integration study
