It is starting to appear that a Moore’s Law of endlessly doubling technological innovation may be just around the corner for the solar power industry, along with drastically falling prices for photovoltaic cells. That means that for the first time, a viable alternative is arising to the fossil fuel generation of power. The solar industry has grown so rapidly over the last 18 months, and appears likely to continue to grow, that the full and long-awaited combination of falling unit costs and relentless technological innovation is already underway. China and Taiwan are leading the technology, although the United States, particularly California, is catching up fast.
