| Summary: | Over the 20-year period between 1990 and
2010, strong demo¬graphic and economic growth around the
world caused global primary energy consumption to grow at a
compound annual rate of 2 percent annually. Even so, falling
energy intensity (the amount of energy used to produce a
unit of economic output) meant that global energy demand in
2010 was more than 20 percent lower than it otherwise would
have been. The energy intensity of the global economy fell
during the period from 10.2 to 7.9 megajoules per U.S.
dollar (2005 dollars at PPP). The reduction was driven by
cumulative improvements in energy efficiency, partially
offset by growth in activity, resulting in energy savings of
nearly 2,300 exajoules over the 20-year period. Doubling the
rate of improvement of global energy efficiency is one of
the three complementary objectives of the Sustainable Energy
for All (SE4ALL) initiative. Launched in the UN General
Assembly in September 2012 and co-chaired by the president
of the World Bank Group and the UN Secretary-General, SE4ALL
calls on governments, businesses, and civil society to
address urgent energy challenges, including energy
efficiency, by 2030. |
