A comparative study of energy and carbon efficiency for emerging countries using panel stochastic frontier analysis

Area of Science:

• Environmental Economics
• Energy Policy
• Econometrics

Background:

• Rising global energy demand necessitates efficient energy use to mitigate accelerating carbon emissions.
• Technological advancements are expected to improve energy efficiency, but the high cost of low-carbon technologies may counteract these gains.
• Balancing economic development with ecological sustainability in energy consumption is a critical global challenge.

Purpose of the Study:

• To analyze energy efficiency considering both economic and ecological dimensions in emerging economies.
• To identify factors influencing energy efficiency and carbon inefficiency.
• To determine countries that achieve both economic energy efficiency and reduced carbon inefficiency.

Main Methods:

• Stochastic Frontier Analysis (SFA) applied to 21 emerging countries from 1995-2016.
• Utilized Cobb-Douglas production function incorporating energy consumption and economic complexity index.
• Comparative analysis of economic and carbon inefficiency levels.

Main Results:

• Mexico exhibited high economic energy efficiency but also the highest carbon inefficiency, indicating a gap in ecological performance.
• Six countries were identified as 'frontier countries' for demonstrating simultaneous improvements in economic energy efficiency and reductions in carbon inefficiency.
• Significant variations in energy efficiency and carbon performance were observed across the selected emerging economies.

Conclusions:

• Economic energy efficiency alone does not guarantee overall sustainability; ecological impact must be concurrently addressed.
• Policy interventions should focus on promoting technologies and practices that enhance both economic and environmental aspects of energy use.
• Identifying and learning from 'frontier countries' can guide other emerging economies toward sustainable energy development.
