What made solar panels so cheap? Thank government policy.

From an economic perspective, the core challenge of climate change is that the standard way of doing things — the dirty, carbon-intensive way — is typically cheaper than newer, lower-carbon alternatives.

Solving the problem means driving down the cost of those alternatives. Simple, right?

But in practice, it’s not so simple. In fact, we still don’t have a very good grasp on exactly what drives technological innovation and improvement. Is it basic scientific research? Early-stage R&D? Learning by doing? Economies of scale?

If we want to make clean technologies cheaper, we need a better understanding of how the process works. Among other things, Silicon Valley types are spending billions on “moonshot” startup initiatives — it would be nice if that money were spent effectively.

There is a voluminous academic literature on these subjects, but a new paper in the journal Energy Policy helps to cut through the fog. It focuses on one specific technology and seeks to identify, and quantify, the various forces that drove down costs.

That technology: good old solar photovoltaic (PV) panels, which have declined in cost by around 99 percent over recent decades.
