Solar energy has plunged in price – where does it go from here?

There are two inflection points for renewables:

1. Cheaper than NEW CONSTRUCTION of coal or gas 2. Cheaper than OPERATING COST of coal and gas

We have passed inflection point 1 in the last couple years. That's why the predictions were off. As soon as we hit inflection point 1, new construction switches from goal and gas to renewables.

This will continue until we start getting instability problems, but cheaper storage (batteries or whatever) will ameliorate this.

The next inflection point will make the current rate of growth look slow. When renewables are cheaper than the operating cost (forget about paying back the capital), the entire coal and gas installed base becomes a stranded asset and it will be replaced at whatever rate we can build out renewables.

I for one would not mind mandatory installations on new buildings within the bay area (East Bay).
