Electric bike batteries can be particularly dangerous and tricky to dispose of.

Some technologies could rapidly cut emissions, while others do little to fight climate change. The House bill favors the latter while nixing support for the former.

Even the best batteries fall far short of animal metabolism for energy storage. Fueling robots with ‘food’ could narrow the gap.

A detailed MIT analysis identifies some promising options but also raises unexpected concerns.

Consumers in Britain are paying for clean power that was never actually generated or used.

Battery management systems now blend physics and machine learning, delivering real‑time insights to boost safety, efficiency and lifespan even under heavy use.

To really compare different electricity sources, you also have to look at the roles they play in keeping the lights on and their drawbacks.

New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.

Electric car charging becomes less efficient in colder weather, but a new strategy for manufacturing battery electrodes could speed things up.

When a spacecraft is too far from the Sun to use solar panels, it needs a different reliable source of power.
