ENERGY METALS

The energy transition is the movement from fossil fuels to renewables as the primary source for energy generation. What determines the start and endpoint of an energy transition? This is not an easy question to answer since many energy systems are in a constant state of flux, albeit very slowly in many cases. In terms of national primary energy use, Smil (2010) argues that the time when a new energy source captures five percent of total energy demand is a reasonable benchmark for the start of a transition.
