Energy storage is rapidly expanding as a grid resource. Batteries, flywheels and pumped hydropower are important ways to soak up and release electrons on demand. However, many people, especially first responders, are concerned about the safety risks of stored energy and worry these installations are cropping up faster than regulations can keep up.

The entire fleet of this new airliner was grounded after flames and smoke erupted in several aircraft. The investigation showed engineering problems with the batteries, as well as deficiencies in testing and safety systems.
