Solar, wind, and batteries: a winning trifecta

Solar energy and wind power are inexaustible sources of cheap renewable energy–but there’s a fatal flaw. They are inherently intermittent, and this makes them poor candidates for providing dispatchable power. But coupled with megawatt scale batteries, solar and wind become star performers..

Smart energy storage systems are the key to fully unlocking the potential of intermittent renewable energy.
