Gas stoves use non-renewable energy sources Gas stoves use natural gas, a non-renewable fossil fuel, and emit gases such as carbon dioxide and methane. In the United States, gas stoves emit a massive 6.8 million tons of carbon dioxide each year.
How does an improved cooking stove work?
What is an Improved Cookstove (ICS)?
- An insulated combustion chamber around and above the fire improves fuel combustion and the mixing of gas, flame, and air.
- Maximum transfer of combustion heat from the flame and hot gases to the cooking pot.

The best option for cooking with electricity is undoubtedly IH, which is 84% efficient compared to gas’s 40% efficiency. Ceramic glass stoves that use halogen elements as a heat source are a close second, as both options provide heat almost instantaneously, reducing wasted energy.
Why the traditional oven is considered harmful for health?
Open flame and primitive cook stoves are fueled by solid materials such as coal or biomass (wood, dung, crop residues). These fuels release harmful particles into the air during combustion. Regular inhalation of these particles can cause illnesses such as asthma, lung disease, and pneumonia.
Why are clean cookstoves important?
There is solid evidence that cooking with clean cook stoves and fuels reduces harmful emissions of particulate matter and black carbon and improves public health. Clean cooking solutions reduce emissions of key climate forcers, including both greenhouse gases (GHGs) and short-lived climate pollutants (SLCPs).
