Economics of Energy Storage. The past decade has seen a rapid decline in the cost of energy storage technologies — in particular, costs of lithium-ion battery energy storage systems (BESS) have dropped 70% since 2012, and are forecasted to drop below the $200/kWh (€160/kWg) threshold by 2019. This precipitous decline has made the
By 2050, over 80% of America''s electricity could be supplied by renewable wind and solar energy. However, wind and solar cannot provide electricity around the clock.
