Prof. Piekle Jr.: How Fast Does Energy Access Occur? ‘In 1920, only 35% of Americans had electricity access. This total reached 100% by the mid-1950s’
'China went from 35% in 1970 to 100% by about 2005-a similar rate to that of the U.S. a half-century earlier'
'Mexico was at about 35% electricity access in 1930, and has yet to get all the way to the 100% mark'
'India is following a much shallower trajectory of electricity access, going from about 25% in 1980 to 65% in 2010'
