Marking points
B1 (a) · 1 mark · States wind is a renewable resource.
B1 (b) · 1 mark · Gives a relevant advantage (e.g., 'no greenhouse gases', 'renewable').
B1 (b) · 1 mark · Gives a relevant disadvantage (e.g., 'unreliable', 'visual pollution').
B1 (c) · 1 mark · States the main energy transfer correctly.
Worked solution
a) Wind is a renewable energy resource.
b) Advantage: Wind turbines do not release greenhouse gases when generating electricity. Disadvantage: Wind energy is not constant and may not always meet demand.
c) The main transfer is from the kinetic energy of the wind to electrical energy.
