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. In 2011 Jacobson et al. proposed a 100% WWS (wind, water, solar) energy system which can supplant the current fossil fuel industry. They found that production cost of WWS is exactly same as current fossil fuel-derived energy systems and that includes costs of production, storing, and transmission (with transmission losses). Their conclusion is that “ … barriers to a 100% conversion to WWS power worldwide are primarily social and political, not technological or even economic.” 2.
