Nuclear and hydroelectric possessed the same percentage of energy consumption, both took up 6% of energy consumption. Saudi Arabia and Canada accounted for the highest oil reserves, with 20% and 14%. Saudi Arabia and Canada accounted for the highest oil reserves. Four mideast countries, Iran, Iraq, Kuwait and United Arab followed behind, each having 8 to 10% of global reserves.
The line chart shows the wide variation in the world oil prices from 2000 to 2025. In 2000, a barrel of oil cost a mere 33 dollars a barrel, which the price decreased in the following three years. In 2003, the price of oil increased sharply and reached its highest peak in 2006 of 60 dollars a barrel. Since then, the price of oil dropped to under 50 dollars a barrel in 2010 and remain at that level for the following years.
