The BIGGEST problem with clean energy

As counterintuitive as it might seem, an incredibly efficient way to "store" renewable energy is Bitcoin.
Let me explain: as we know, renewable energy is intermittent, however such intermittence is offset in time on each location and production method. In other words, when energy production runs out in a location/facility, it spikes elsewhere.
By using the energy in excess to mine bitcoin, each facility could convert such unused energy into an economic asset that could be spent later to purchase energy from elsewhere when the production is down. Of course this could happen only IF bitcoin mining goes completely (or mostly) on renewables.
