How many km2 of solar panels in Spain and how much battery backup would it take to power Germany

Unless the safety, space, environmental, raw material, and energy considerations can be overcome, PV-Spain is a poor choice for solving Germany’s, Europe’s, or the global power dilemma. Alone the material requirements for the panels (see silicon and silver) or batteries cannot be met. Moreover, the energy required to build and maintain the batteries for such a large solar facility in Spain – also referred to as energy-Return-On-energy-Invested eROeI – have not yet been considered in this paper.
