Dear Student
Domestic use of the following of the conventional sources of energy is:
1. Natural Gas: Natural gas is used as fuel. It is used to generate electricity,fuel vehicles, cook food etc.
2. Coal: Bituminous coal is largely used for domestic purposes such as cooking.
3. Petroleum: Petroleum product such as kerosene is used for domestic purposes as fuel.
Solar energy (non-conventional sources of energy) can replace use of coal used for cooking (domestic use).
