Cooking helped us survive… modern energy cooking services can make us thrive

About 30 years ago, I lived in a village in China's Xinjiang province where I remember having to collect firewood for cooking and heating as part of my chores. In fact, as part of summer homework, we also needed to turn in a big bundle of firewood when the school started in the fall, which would be used to heat the classroom, together with coal.

Cooking with firewood was not only a tough job because of all the smoke but also required skills and experience. If the fire was not well controlled, the rice could be easily burned. Before I was old enough to take on this job, our family moved to a city apartment with access to district heating and we also started to use liquefied petroleum gas (LPG) for cooking. Since then, our daily life has been transformed.
 
However, not everyone is as lucky as me. 

In China, a South-South Exchange Helps Countries Yearning for Clean and Efficient Heating Learn from Each Other

Places with cold climates need access to a reliable and efficient heat supply for the health of their population. But in developing countries, the majority of rural and peri-urban households do not have access to centralized heating or gas networks. Instead, they use traditional heating stoves that use solid fuels like coal, wood, and dung for heating. These stoves are often inefficient (with thermal efficiency as low as 25%-40% compared to 70% or above for efficient stoves) and emit large amounts of pollutants (e.g., CO and PM2.5), causing indoor and outdoor air pollution with negative health and environmental impacts.

While most people link air pollution only to burning fossil fuels, other activities such as agriculture and biomass burning also contribute to it. The complexity of air pollution can be explained by analyzing the composition of the PM2.5, one the most important air pollution indicators.
