Silicon Shortage Threatens Solar Energy Growth

As demand for clean energy continues to grow, the solar industry forecasts millions of photovoltaic systems will dot the landscape by the end of the decade. However, a severe shortage of the silicon used in the systems threatens to dampen solar’s growth.

According to a recent solar-energy report from the nonprofit Energy Foundation, the U.S. solar industry could grow by more than $6 billion per year if the technology becomes cost-competitive with electricity from fossil-fuel sources.
