Question

Read the following passage carefully and answer the question that follow:

The concept of renewable energy has gained significant attention in recent years to reduce the dependence on fossil fuels and combat climate change. Solar, wind, hydroelectric, geothermal and biomass are examples of renewable energy sources. These sources are considered renewable because they can be replenished naturally, unlike fossil fuels, which take millions of years to form and are One finite. One of the main advantages of renewable energy is that it is environmentally friendly. Renewable energy sources do not produce greenhouse gases, which contribute to climate change, They also do not produce harmful air pollutants like sulphur dioxide and nitrogen oxide.

Questions:

(i) What is renewable energy?

(ii) What are the examples of renewable energy sources? 

(iii) What is the main advantage of renewable energy ?

(iv) Give two examples of harmful air pollutants.

Answer 1

(i) Renewable energy refers to energy that comes from sources that can be naturally replenished, such as solar, wind, and water, unlike fossil fuels, which are finite.

(ii) The examples of renewable energy sources are solar, wind, hydroelectric, geothermal, and biomass.

(iii) The main advantage of renewable energy is that it is environmentally friendly, as it does not produce greenhouse gases or harmful air pollutants that contribute to climate change.

(iv) Two examples of harmful air pollutants are sulfur dioxide and nitrogen oxide.
