Worldwide markets for solar panels are growing as units become more efficient and less costly for generating electricity.  Rapid adoption of solar panels worldwide is occurring as systems provide peak power efficiently.   The ability to remain competitive depends upon the ability to develop technologically advanced products and processes. 

What better investment in infrastructure on the part of a government than solar power?  Cheap energy promises to provide water, cheap manufacturing, electric vehicles, all sorts of things more useful than a war that the government might alternatively spend its money on.
