Why clean cooking is important?
Clean cooking is part of basic services necessary to lead a healthy and productive life and saves house- holds time and money. Efficient cookstoves reduce the amount of fuel needed to cook, thus reducing the burden on families who would otherwise have to collect it, buy it, or trade their food for it.

Is kerosene a clean cooking fuel?
Besides the focus on “solid” fuels, the designation of kerosene as a “clean” fuel was in part due to views of some international agencies and academic researchers which considered kerosene as less polluting in the larger context of household fuels (Grieshop et al.
Is stove renewable?
Gas Stoves Use a Non-renewable Energy Source
Gas stoves use natural gas which is a non-renewable, fossil fuel and emits gases like carbon dioxide and methane. In the US, gas stoves emit a massive 6.8 million tons of carbon dioxide every year.
How does an improved cooking stove work?
What is an Improved Cookstove (ICS)?
- Better combustion of the fuel by providing an insulated combustion chamber around and above the fire, which leads to a better mixing of gases, flame and air.
- Maximum transfer of heat of combustion from the flame and the hot gases to the cooking pot.
Why have improved cook stove initiatives in India failed?
Most improved biomass stove programs in India have failed to achieve the desired levels of adoption or goals of stemming deforestation rates, addressing fuel shortages, or curbing respiratory disease (Hana, Duflo, & Greenstone, 2012).

Renewable hydrocarbon biofuels (also called green or drop-in biofuels) are fuels produced from biomass sources through a variety of biological, thermal, and chemical processes. These products are chemically identical to petroleum gasoline, diesel, or jet fuel.
Why are clean cookstoves important?
There is solid evidence that cooking with clean cookstoves and fuels improves public health by reducing harmful emissions of particulate matter and black carbon. Clean cooking solutions reduce emissions of major climate forcing agents including both greenhouse gases (GHGs) and short-lived climate pollutants (SLCPs).

Why is LPG called clean fuel?
A mixture of hydrocarbons (butane and propane in India), LPG is a clean fuel because it burns cleanly in stoves with very few emissions.
Why do planes use kerosene?
Kerosene maintains a low viscosity during flights thanks to its low freezing point. This means it will keep the plane running as it should and won’t clog up the engine. Kerosene is much cheaper than gasoline, making it a more affordable option for airlines.
Are there solar powered stoves?
Yes, solar power can run a stove. Solar camp stoves are designed to reflect available sunlight into a heat trap in the center of the oven, where you place the cooking dish. Quality solar stoves can cook pretty much everything a regular stove can.

When inhaled on a regular basis, these particles can cause diseases such as asthma, lung disease and pneumonia.
What is traditional Chulo?
‘Chulo’ is a traditional Nepali stove that is made out of mud, used for cooking in rural areas (where sophisticated gas/electric stoves arent prevalent), as well as urban areas (as an alternative oven). Most Nepalis prefer food cooked in a Chulo due to its rich and authentic taste.
What are the advantage of the improved cooking stove over the traditional one?
The benefits of ICS include health improvements from better indoor air quality, cooking time savings, aesthetic improvements and improved social standing from the use of cleaner stoves, and environmental benefits to society, such as reduced black carbon or greenhouse gas emissions and deforestation.

Is coke is a clean fuel?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.

What is a clean cooking stove?
Back to Solution Summary. Project Drawdown defines clean cookstoves as solar-powered or fuel-burning household stoves that reduce greenhouse gas emissions by increasing thermal efficiency, reducing specific emissions, or increasing ventilation.
What issues does the score stove hope to address?
The Score Stove may help to provide small-scale electricity generation to areas where supply is limited. As the stove traps the heat and smoke which are produced by the fire, it reduces the amount of smoke that escapes into the air and therefore minimizes negative health effects for the families.
Which fuel source is the most green or most environmentally friendly?
Solar fuel
Solar is probably the greenest fuel ever. Solar panels capture the incoming solar heat/radiation placed on top of the vehicle. The sunrays are converted into electricity which is stored into the batteries.

-As we have got our answer that nature gas is the cleanest fuel means it is least polluting fuel as well, let us now focus on the three other options. 1.
What is the best heat source for cooking?
Gases have significantly higher kinetic energy than water. Since heating food for cooking involves transferring heat energy from a source to the food product, it makes sense that the heat source with the most energy would be the most efficient option for cooking. Steam is that high-efficiency heat source.
