Summary
Many Chinese households are switching from solid fuels to clean energy. Understanding why they stop using solid fuel stoves is key to accelerating this household energy transition for climate and health benefits.
Area of Science:
- Environmental Health
- Energy Policy
- Sociology
Background:
- Household solid fuel (biomass, coal) burning is a major contributor to climate change and a significant health risk.
- The process and reasons for households discontinuing solid fuel stove use after adopting cleaner alternatives remain understudied.
Purpose of the Study:
- To assess trends in household stove and fuel use, specifically focusing on the uptake of clean fuels and the suspension of solid fuel use.
- To identify determinants influencing clean fuel adoption and solid fuel suspension among Chinese households.
Main Methods:
- A multi-provincial cohort study involving 753 Chinese adults was conducted.
- Data were collected on the uptake, use, and suspension of household stoves and fuels over a 20-year period.
- Statistical analysis was performed to evaluate the determinants of clean fuel adoption and solid fuel suspension.
Main Results:
- Over 35% of participants suspended solid fuel use for cooking, and 17% for heating in the past 20 years.
- Factors associated with solid fuel suspension (e.g., younger age, widowed status) differed from those for clean fuel adoption (e.g., younger age, higher income, smaller households, retired status).
- Determinants for earlier suspension (younger age, higher education, poor self-reported health) also varied from those for earlier adoption (higher income).
Conclusions:
- Clean fuel adoption and solid fuel suspension are crucial indicators of household energy transition.
- Joint consideration of both clean fuel uptake and solid fuel suspension is recommended for effective household energy research and planning.
- Focusing on solid fuel suspension can accelerate energy transitions, yielding benefits for both climate and human health.

Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules.

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
