Among the principal energy resources used worldwide, which single fuel supplies about 40% of the world's energy, with much of it going to transportation?
ACoal, mined worldwide
BNatural gas supplies
CNuclear power plants
DOil, pumped worldwide
Answer & Solution
Correct answer: D. Oil, pumped worldwide
1. Among the principal world energy resources, oil supplies about 40% of total world energy use.
2. Much of that oil-derived energy is used specifically for transportation.
3. Coal and natural gas are both major fuels too, but neither is credited with the 40% share attributed to oil here.
4. Nuclear power supplies a much smaller share of world energy than oil does.
