PricewaterhouseCoopers, an international accountancy and professional services firm, published an ambitious plan for Europe's energy future. Three research institutes (PIK, IIASA and ECF) have collaborated with PwC.
Their analysis for the plan asserts a pan-European, cross-Mediterranean grid (dubbed SuperSmart Grid) will enable Europe to meet their electricity needs 100% from renewable electricity.
If this kind of geographically optimized power mix is achievable thanks to a high-voltage direct current (HVDC) transmission system, the same is possible in North America.
