The Alps help tackle climate change?

Next time you head to the Swiss Alps for your family ski vacation, you might want to know what's beneath you. It's a "giant water battery" called "Nant de Drance" in the canton of Valais, helping to tackle climate change with the use of renewable energy. The battery "provides the same energy storage capacity as 400,000 electric car batteries," according to CNN. At the snap of a finger, the hydropower plant can switch from storing energy into an electricity provider. The $2 billion project "could play a vital role in stabilizing Europe's electricity grid," according to one official.
