[TheWorld] Oil Crises and Climate Challenges: 30 Years of Energy Use: stop using cars!
This new publication examines how energy efficiency and factors such as economic structure, income, lifestyle, climate, prices and fuel mix have shaped developments in energy use and CO2 emissions in IEA countries since the organisation was founded 30 years ago.
One of the major findings of the report is that IEA countries have significantly reduced the need for energy to fuel economic growth. Compared to 1973, it now takes one-third less energy to produce a unit of GDP in IEA economies. An important reason for this development is the considerable energy savings that have taken place in the various branches of manufacturing, in different end-uses in households and commercial buildings, and for different modes of passenger and freight transportation.
The decline in oil demand was offset by the growth in transport oil demand, so that IEA oil demand levels in 2001 were comparable to those in 1973. The most important reason behind the growth in transport demand is the increased use of cars for passenger travel. Car ownership levels have risen by 100% or more in many countries since 1973, and while car engines have become more efficient over the years, cars have also become bigger, heavier and more powerful. This has served to limit improvements in average fuel efficiency. As a consequence, oil use for cars grew almost 50% between 1973 and 1998.
