Question

environmental benefits of wind energy
circle the correct answer.

1. wind energy works through:

a. manipulate wind currents
b. harvest the kinetic energy of the wind
c. manipulate wind cycles
d. all of the above

1. wind energy produces __________ carbon emissions.

a. 0
b. 189 million tons
c. 188 thousand tons
d. 122 thousand tons

1. the use of wind energy also means a significant reduction of ____ in the air.

a. co2
b. so2
c. nox
d. all of the above

1. the use of wind energy also saves:

a. billions of gallons of water
b. hundreds of gallons of water
c. thousands of gallons of water
d. millions of gallons of water

1. wind energy also stands out for:

a. big footprint
b. small footprint
c. contaminating
d. water consumption

Explanation:

Question 1

Wind energy harnesses the kinetic energy of wind (wind turbines convert wind's motion into electricity). Options A and C are incorrect as we don't manipulate wind currents/cycles but harvest their energy.

Wind energy is a renewable, clean energy source with 0 direct carbon emissions during electricity generation (unlike fossil fuels). The other options are incorrect values for wind energy’s emissions.

Wind energy reduces air pollutants like CO₂ (greenhouse gas), SO₂ (causes acid rain), and NOₓ (causes smog/acid rain). So all these pollutants are reduced.

Answer:

B. harvest the kinetic energy of the wind
