This study critically reviews policies addressing the role of multiple energy sources in achieving carbon neutrality goals, with a focus on income and energy consumption in transition economies, specifically China and Uzbekistan. As both nations undergo significant economic transitions, their energy consumption patterns are evolving in response to modernization and policy changes. Utilizing data from 2012 to 2022, this study examines the consumption of various energy sources, including coal, wood, electricity, and liquefied natural gas (LNG), within the context of these countries' carbon neutrality objectives. Our findings reveal that income levels significantly influence energy consumption behaviors, with low- and high-income households in both China and Uzbekistan exhibiting distinct preferences for energy sources. The study integrates social survey data, economic variables, and policy analysis to explore how energy consumption is shaped by income disparities, fluctuating prices, and environmental goals. By drawing on historical contexts and previous scholarly works, this research provides a comprehensive understanding of the complex interplay between income, energy use, and policy in transition economies. The findings offer valuable insights for policymakers aiming to develop sustainable energy strategies that align with carbon neutrality goals while addressing the unique challenges of income disparity and energy consumption in China and Uzbekistan.
