Share
LPG (liquefied petroleum gas) holds advantages over wood as a domestic fuel for several compelling reasons:
1. Cleaner Burning: LPG combustion is cleaner, emitting fewer pollutants like particulate matter and harmful gases, enhancing indoor air quality and reducing health risks compared to wood burning.
2. Convenience and Accessibility: LPG is readily available, portable, and easier to control than wood. It eliminates the laborious tasks of wood gathering, chopping, and storage, making it more convenient for household heating and cooking needs.
3. Consistency and Dependability: LPG provides consistent heat without variations in quality or moisture content, ensuring a more dependable and constant energy source than wood.
4. Environmental Impact: Wood burning contributes to deforestation. LPG usage reduces this impact by minimizing the pressure on forests, curbing deforestation and forest degradation.
5. Safety Measures: LPG poses fewer safety hazards in terms of handling, storage, and combustion compared to wood stoves or open fires, thereby reducing the risks of accidents, burns, or carbon monoxide exposure.
6. Efficiency: LPG appliances often boast higher energy conversion efficiency than traditional wood-burning stoves, utilizing the fuel’s energy content more effectively.
Collectively, LPG emerges as a preferred domestic fuel over wood due to its cleanliness, convenience, reliability, reduced environmental impact, safety considerations, and higher efficiency in catering to household energy requirements.
LPG is a good fuel as compared to wood as it readily available and it is cheap. It burns easily in air at a moderate rate and it produces a large amount of heat. It does not leave behind any undesirable substances.
