At the moment we don't have any way of storing bulk electricity- we have to generate it as we want it. And when we wan't it-not just when it's windy!

Hydroelectric plants like the one in Wales are used to sort of store electricity. When they have spare power they pump water up the hill, when they need electricity the water up the hill turns the turbines on its way back down.
