What percentage of the worlds population has access to electricity?

Answer 1

"Some 1.6 billion people, about one quarter of the world?s population,
have no access to electricity today. Eighty percent of these people
live in rural areas of the developing world, mainly in South Asia and
sub-Saharan Africa where rapid urban migration and population growth
will occur over the next
several decades."

Of course, this is only an estimate. An undated Greenpeace document
puts the figure for people without access to electricity at "more than
2 billion."
