Access to affordable, stable energy supplies is critical for economies throughout the world. For developing countries, affordable energy can offer a pathway to a better quality of life. But between 2000 and 2010, world oil prices became much less affordable. The average global oil price advanced from approximately $25 per barrel to more than $100 per barrel – far outpacing rates of inflation in most countries.
Many books and articles have been published that argued that the increase in prices has been due to oil speculation, the restriction of supplies by OPEC, growth in developing countries, peak oil, or various geopolitical factors. Regardless of the cause, the response to higher prices in developed and developing countries may be surprising.
