ving Forces for Energy Demand 2010
& Fridtjof, 2006). The energy efficiency improvements achieved across the OECD
countries show that well-designed policies can result in substantial energy
savings. In the United States nine specific policies and programs reduced primary
energy use in 2002 by approximately 11%. (Geller, Philip, Rosenfeld, Satoshi, &
Fridtjof, 2006) . Figure 2-12 shows how energy use per GDP has seen efficiency
gains averaging 1,2% from 1980 to 2000 globally. This has been achieved as
major OECD countries have significantly reduced the need for energy to fuel
economic growth over the last three decades. Today major OECD economies use
a third less primary energy to generate a unit of GDP than in 1973. These
efficiency gains started as a direct result of the two oil price shocks. Between
1973 and 1983, the fall in primary energy intensity averaged 2.2%/year. After
1983 and until 1990, TPES/GDP declined at a more modest average rate of
1.3%/year (Geller, Philip, Rosenfeld, Satoshi, & Fridtjof, 2006) It remains to be
seen what will be the longer lasting efffect of the 2007/2008 price shock.

(ExxonMobil, 2009)
While energy intensity grew in many developing countries, in China, between
1980 and 2000, primary energy demand rose by a factor of two, while GDP
increased six-fold. As a result, energy intensity improved by nearly 6% per year
during this period (Can, Letschert, McNeil, Zhou, & Sathaye, 2009). However,
between 2002 and 2004, energy demand grew much faster relative to GDP,
causing energy intensity to rise. This reversal was driven mainly by surging
