Question 60

Wind energy can be converted to electricity using kinetic energy from moving air.

Wind energy is harnessed by converting the kinetic energy produced by moving air into electricity, typically through wind turbines.

A) Solar energy

Solar energy is derived from sunlight and is converted into electricity using photovoltaic cells or solar thermal systems. It does not involve the kinetic energy of moving air, making it incorrect in this context.

B) Biomass energy

Biomass energy is produced from organic materials, such as plants and animal waste, which are burned or converted into biofuels to generate electricity. This energy source does not rely on the kinetic energy of wind, hence it is not the right answer.

C) Geothermal energy

Geothermal energy is obtained from the heat stored beneath the Earth's surface. It primarily utilizes thermal energy rather than kinetic energy from moving air, making it an unsuitable choice for this question.

D) Wind energy

Wind energy specifically refers to the energy obtained from the movement of air, which can be converted to electricity through wind turbines. This option directly addresses the question by focusing on kinetic energy derived from wind.

Conclusion

Wind energy is the only option that directly involves the conversion of kinetic energy from moving air into electricity. The other options, while valid energy sources, do not utilize kinetic energy from wind, thereby confirming that D is the correct answer.
