Which of the following is a renewable source of energy?

Wind is considered a renewable source of energy because it is generated from natural processes that are continuously replenished. Wind energy is harnessed through wind turbines, which convert the kinetic energy of moving air into electricity. As long as the sun shines and the Earth rotates, wind will be produced, making it an inexhaustible resource in human time scales.

In contrast, fossil fuels such as coal and natural gas are non-renewable resources. They are formed over millions of years from the remains of ancient plants and animals, and once they are extracted and used, they cannot be replaced on a human timescale. Nuclear energy, while not dependent on fossil fuels, relies on finite uranium resources and presents challenges related to waste disposal and reactor safety. In summary, wind stands out as a sustainable energy source that can significantly contribute to reducing greenhouse gas emissions and combating climate change while being continually accessible.
