- There are commercial and non-commercial sources of energy. Commercial sources are coal, petroleum and electricity as they are bought and sold. Noncommercial sources of energy are firewood, agricultural waste and dried dung.
- These are non- commercial as they are found in nature/forests. While commercial sources of energy are generally exhaustible (with the exception of hydropower), non- commercial sources are generally renewable.
- More than 60 per cent of Indian households depend on traditional sources of energy for meeting their regular cooking and heating needs. Note: This Data might have changed due to the introduction of Pradhan Mantri Ujjwala Yojana.

Which of the following are non-commercial sources of energy?1. Firewo...
Non-commercial sources of energy refer to those sources that are not primarily used for commercial purposes or for profit-making. They are often locally available and are utilized by individuals or communities for their own energy needs. Out of the given options, firewood and agricultural waste are non-commercial sources of energy.
1. Firewood:
- Firewood is a traditional source of energy that has been used for centuries for heating and cooking purposes.
- It is obtained from cutting and gathering dead trees or branches from forests or agricultural fields.
- Firewood is primarily used in rural areas and developing countries where access to modern energy sources is limited.
- It is considered a non-commercial source as individuals collect firewood for their own use without involving any commercial transaction.
2. Agricultural waste:
- Agricultural waste refers to the residues or by-products generated from agricultural activities such as crop harvesting and processing.
- Examples of agricultural waste include crop stalks, husks, straw, and bagasse.
- These waste materials can be utilized as a source of energy through various processes such as combustion, gasification, or anaerobic digestion.
- Agricultural waste is often used as a fuel for heat and power generation in rural areas, especially in regions with a significant agricultural sector.
- Similar to firewood, agricultural waste is a non-commercial source of energy as it is usually obtained and utilized by farmers or local communities for their own energy needs.
3. Electricity:
- Electricity, on the other hand, is not a non-commercial source of energy. It is a commercial source that is produced, transmitted, and distributed by various entities for monetary gain.
- While electricity can be generated from non-commercial sources such as solar, wind, or hydropower, the distribution and consumption of electricity involve commercial transactions.
Therefore, the correct answer is option 'A' - 1 and 2 Only, as firewood and agricultural waste are non-commercial sources of energy while electricity is a commercial source.
1. Firewood:
- Firewood is a traditional source of energy that has been used for centuries for heating and cooking purposes.
- It is obtained from cutting and gathering dead trees or branches from forests or agricultural fields.
