Solar and wind are clearly the future of energy, yet the adoption of renewables has been largely constrained by their intermittent nature. Innovations in energy storage technology might change that. In the last year alone energy storage has grown by 6 GWh of capacity globally and it has the potential to grow 13 times present levels by 2024. With energy storage costs having fallen by 85% since 2010, solar-plus-storage suddenly becomes a great option, especially when combined with the fast growth of solar and wind markets. All these developments are set to remake the renewable energy landscape.
