VOX just released a video on the "Duck Curve" phenomenon that arises as a result of renewables[1]. Does anyone here have any insight on what the state is trying to do to mitigate negative downstream affects of the duck curve? [1] [VIDEO]

That's because solar usage has created a "duck curve" I would imagine it would be even more unfair to make normal energy users pay for that: [VIDEO]

It's not so much that they can wind down the energy they make, it's the fact that they cannot store energy for when there's increased demand. [VIDEO]
