Name two energy sources that you would consider to be renewable. Give justification for your choices. Can these energy sources be pollution free? List two reasons in support of your answer.

The examples of two energy sources that can be considered renewable are solar energy and wind energy.

• Solar energy in the form of sunlight is one of the most abundant, freely available, and cleanest sources of energy on the Earth. This usage of this energy does not release any harmful substances into the environment. Thus, it is eco-friendly and does not cause pollution.
• Wind energy is obtained from the fast-blowing air. Windmills are established and used to harness wind energy and utilize it to produce electricity. Since air is blowing due to uneven heating of the Earth's surface and heating of the Earth will remain forever, wind energy is a renewable source of energy. It is also a clean source of energy and does not cause pollution.
