In this video from NOVA's Energy Lab, learn how finding better ways to store electricity is critical for a sustainable energy future. Inconsistent energy demands mean that utility companies must keep power plants on standby to provide enough electricity during times of peak consumption. Renewable energy sources such as wind and solar are dependent on weather and cannot take the place of costly power plants without a way to store electricity. The cost of battery storage has come down greatly in recent years, and scientists and engineers are currently working on developing efficient and reliable ways to store excess electricity produced from renewable energy sources.
