1.  Are renewable energy systems even viable or are they just an Utopian dream of impractical scientists? And even if they are viable wouldn’t it cost an arm and a leg to make them viable?

Among the multitude of scientific journal articles, which answers both these questions separately, one article answers both these questions succinctly in a single paper.
