Ignore the Smears: Germany’s Green Energy is 1/3 of its Power, Price Falling, Coal Down

1. The problem is the electric grid.

Renewable energy sources come with big fluctuations in voltage. That's especially true for wind. Large-scale use of such electricity-sources needs a modern and well-maintained power grid that can steer and balance such fluctuations to ensure that everybody gets exactly the amount of voltage he expects from an AC socket.

At least in the short term, nuclear energy is indispensable: It creates a reliable baseline to which the fluctuating contributions of renewable energy sources are then added.
