Give one domestic use of each of the conventional sources of energy. Which non-conventional sources of energy can replace them for the same domestic use?
Answers
Answer:
Explanation:As the consumption of energy grows, the population depends more and more on fossil fuels such as coal, oil and gas day by day. There is a need to secure the energy supply for future since the prices of gas and oil keep rising by each passing day. So we need to use more and more renewable sources of energy. For the effective exploitation of non-conventional sources, there has been an establishment of a separate department namely “Department of non-conventional sources of energy” by the government of India.

Renewable resources provide energy in four important areas like :
Electricity generation
Water heating or cooling

Types of Non-convention sources
Solar Energy
Wind Energy
Tidal Energy
Geothermal Energy
Biomass
Solar Energy
Solar energy is harnessed by converting solar energy directly into electrical energy in solar plants. Photosynthesis process carries out this process of conversion of solar energy. In photosynthesis, green plants absorb solar energy and convert it into chemical energy. Solar energy is an essential energy of all non-conventional sources but its usage amount is very less. It is the most important non-conventional source of energy and it gives non-polluting environment-friendly output and is available in abundant.
Uses of Solar energy
A solar cooker directs the solar heat into secondary reflector inside the kitchen, which focuses the heat to the bottom of the cooking vessel. It has a covering of a glass plate. They are applicable widely in areas of the developing world where deforestation is an issue, and financial resources to purchase fuel are not much.
Solar heaters also use solar energy to heat water instead of using gas or electricity.
Solar cells also use solar power to generate electricity from the sun.

Wind energy
Wind energy describes the process by which wind is used to generate electricity. As the wind increases, power output increases up to the maximum output of the particular turbine. Wind farms prefer areas, where winds are stronger and constant. These are generally located at high altitudes. Wind turbines use wind to make electricity. There is no pollution because no fossil fuels are burnt to generate electricity. One of India’s largest windmill farm is in Kanyakumari which generates 380mW of electricity.
Biomass energy
Biomass is the organic matter that originates from plants, animals, wood, sewage. These substances burn to produce heat energy which then generates electricity. The chemical composition of biomass varies in different species but generally, biomass consists of 25% of lignin, 75% of carbohydrates or sugar. Biomass energy is also applicable for cooking, lighting, and generation of electricity. The residue left after the removal of biogas is a good source of manure. Biomass is an important energy source contributing to more than 14% of the global energy supply.

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).
