Two million European households could abandon the electrical grid by 2050      (via sciencedaily.com)     Original source 

Researchers report that 53% of European freestanding homes could have supplied all their own energy needs in 2020 using only local rooftop solar radiation, and this technical feasibility could increase to 75% in 2050. The study shows that there is no economic advantage for individual households to be fully self-sufficient under current or future conditions, though in some cases the costs are on par with remaining on-grid. The researchers estimate that self-sufficiency will be economically feasible for 5% (two million) of Europe's 41 million freestanding single-family homes in 2050, if households are willing to pay up to 50% more than the cost of remaining fully grid dependent.
