The electric car makes it possible to partially decarbonize transportation, but the fate of the batteries after their use remains an open problem. Michael Marais/Flickr

Can electric vehicle batteries be recycled?

Between reuse and recycling, what happens to the batteries of electric vehicles?

Meet the power plant of the future: Solar + battery hybrids are poised for explosive growth

The largest category of power plants applying to connect to the US grid are now solar, and over a third of those are hybrids that include battery storage.
Building solar panels over water sources is one way to both provide power and reduce evaporation in drought-troubled regions. Robin Raj, Citizen Group & Solar Aquagrid

These energy innovations could transform how we mitigate climate change, and save money in the process – 5 essential reads

From pulling carbon dioxide out of the air to turning water into fuel, innovators are developing new technologies and pairing existing ones to help slow global warming.

How a few geothermal plants could solve America’s lithium supply crunch and boost the EV battery industry

Lithium is essential for batteries that power electric vehicles and store energy from solar and wind farms. A new U.S. source could provide 10 times more lithium than the country uses today.

Batteries get hyped, but pumped hydro provides the vast majority of long-term energy storage essential for renewable power – here’s how it works

A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.

These 3 energy storage technologies can help solve the challenge of moving to 100% renewable electricity

The US is generating more electricity than ever from wind and solar power – but often it’s not needed at the time it’s produced. Advanced energy storage technologies make that power available 24/7.

The US is worried about its critical minerals supply chains – essential for electric vehicles, wind power and the nation’s defense

Right now, the nation is almost entirely dependent on other countries for minerals that are used in everything from wind turbines to strike fighters and satellites.

As cobalt demand booms, companies must do more to protect Congolese miners

Companies can’t verify that their source didn’t involve artisanal mining. A discussion over responsible sourcing strategies and practices is needed.
