The combination of bar charts and a line graph delineate the actual energy consumption as well as oil reserves and price globally, spanning the years 2000-2025. Overall, oil is the most used material in 2005, reserving mostly in Saudi Arabia.
Specifically, in 2005, a third of the energy consumption referred to oil (37%), following by 28% of coal and 23% of natural gas. Nuclear and hydro-electric are the other two resources in the graph, which both accounting for 6% total. In terms of oil reserves, Saudi Arabia, Canada and Iran were the top 3 nations, with 20%, 14% and 10% worldwide respectively. The United States was recorded to have the least amount of barrels reserved, as a tenth lower than the top country, reached only 2%.
In addition, the price of oil exhibited a sharp incline in the first 5 years, until reaching its peak at nearly $60 per barrel in 2005, which approximately doubled its figure in the beginning of the century. This cost for one barrel then gradually decreased and remained the same at about $50 in the latter part of the period, of which is predicted to keep ranging in 2025.
In essence, . With a stable increase in its cost, these data suggest that the oil twill continue to become the most consumed energy worldwide. However, this is a non-renewable resource, hence, there would be a severe shortage if it is not controllably exploited.
