In a year, roughly (to 20% accuracy) how much energy does the U.S. obtain from wind? (a) 25 quads (b) 250 quads (c) 2.5 quads (d
) 0.22 quads
1 answer:
Answer:
c
Explanation:
A data graph has been attached to the given question which is of the year 2018.
According to it of 101.3 quad Btu total energy produced in USA, 11% is produced by renewable energy resources. that consists of 22% of from wind energy.
there amount of energy produced through wind is 22% of 11% of 101.3 quad Btu, which will be roughly about 2.5 quad Btu
Btu here is British thermal Unit.
hence option c is correct
