We are transitioning from the first age of energy, where we were profligate wasters, building engines that were only 20% efficient, to the age where we use resources more wisely to achieve the same effect. Witness the way Britain’s power grid dropped from shifting 330TWh per annum to around 250TWh mostly from energy efficiencies (eg lighting a room with 10W instead of 100W).
