By 2050, most of the world’s countries may be able to do without fossil energy altogether and get by on renewable sources – wind, water, and sun – alone. This is the conclusion of a group of researchers at Stanford University in the U.S., as reported by Joule. The researchers estimated the energy consumption of 139 countries in 2050, based on the 2012 data and including savings from the move to 100% electric. The study highlights the elimination of energy-intensive activities such as mining, transport, and processing of hydrocarbons and other ores, and the greater energy efficiency of electricity.
