The graphs provide information about worldwide energy consumption, the countries with oil reserves and the world oil prices from 2000 to 2025.

The two pie charts, combined with the line graph, give an overview of some aspects of the energy market.

According to

the first pie chart, the consumption of

oil

was the highest in 2005, accounting for 37% of the energy consumed worldwide, followed by coal and natural gas, taking up 28% and 23% separately. Nuclear power and hydroelectricity evenly contributed to the remaining 12%. Saudi Arabia and Canada are the two countries with the largest

oil

reserves 20% versus 14%. Four Mid-east countries, Iran, Iraq, Kuwait and United Arab follow behind, each having 8 to 10% of the global reserves. Venezuela, Russia and the United States are on the list as well, but account for a smaller share, 6%, 5% and 2% respectively. The line chart shows a wide variation in world

oil

prices in the first decade of the 21st century. In 2000,

oil

cost a mere 33 dollars per barrel, or even less in the following three years. From 2003 onwards, the price surged markedly and

finally

hit a peak of 60 dollars in about 2006. Since

then

, the

oil

price is expected to drop for three years or longer, down to 48 dollars in 2010 and remain at that level throughout the rest of the given period.
