Germany pumped a lot into solar a decade or so ago in order to drive solar down its experience curve. This was expensive, but it was a tremendous gift to the world. You can thank much of the game-changing decline in renewable prices on this sacrifice. If they wanted to buy that same capacity again it would be much cheaper now.

The good experience effects of renewables and storage implies we should go full speed ahead installing them. The side effect of pushing down their prices makes this the most cost effective approach overall. Nuclear, which doesn't have good experience effects, is a different story entirely.
