Overall energy consumption
has risen in almost every country
over the last three decades,
but energy use per capita has not.
China's energy use
per person has nearly
quadrupled since 1980.
Angola's has barely budged.
In the United States,
and some other advanced
economies, per capita energy
consumption has been falling
(or flat) since the early 1980s.
Increasing energy efficiency
is part of the reason for
falling per capita energy use.
