Global demand and supply
Oil is expected to remain the most important fuel in the coming decades, even though its share of global energy use is declining and the share of renewable fuels is expected to increase. The International Energy Agency estimates that
global energy requirements will increase by 1.5
percent per year up to 2030, partly due to the
developing countries of Asia and the Middle East. The oil
share of the total energy mix is estimated to decline
from 34 to 30 percent until 2030.
