Summary of "Energy Efficiency in South Asia: Opportunities for Energy Sector Transformation"

Core Content

This report, authored by Ram M. Shrestha, Tika Ram Limbu, Bijay Bahadur Pradhan, Amnaya Paudel, and Pratik Karki, examines the role of energy efficiency in the energy consumption patterns and sector transformation of five South Asian countries: Bangladesh, Bhutan, India, Nepal, and Sri Lanka. It provides a detailed analysis of historical trends, identifies key drivers of energy use, and outlines potential strategies for improving energy efficiency and reducing energy demand in the coming decades.

Main Points and Key Findings

1. Energy Intensity Trends (2000–2016)

• The energy intensity (energy use per unit of GDP) of South Asian countries declined during 2000–2016.
• Bangladesh: 14% reduction
• India: 36% reduction
• Nepal: 13% reduction
• Sri Lanka: 40% reduction
• Bhutan: 54% reduction (2000–2015)

2. Energy Mix and Fuel Consumption

• Fossil fuels accounted for a large share of total primary energy supply (TPES) in all five countries during 2000–2016.

  • Bangladesh and India: ~75%
  • Sri Lanka: ~57%
  • Nepal: ~21%
  • Bhutan: ~36% in 2014

• Biomass consumption in the residential sector declined across all countries, with:

  • Bangladesh: 64% in 2016
  • India: 70% in 2016
  • Nepal: 95% in 2016
  • Sri Lanka: 80% in 2016
  • Bhutan: Declined from 91% in 2005 to 87% in 2014

3. Growth in Productive Energy Use (TPUE)

• The total productive use of energy (TPUE) grew at varying rates from 2000–2015:
  • Sri Lanka: 3%
  • Bangladesh: 9%
• In India and Sri Lanka, improvements in energy intensity helped reduce TPUE growth.
  • India: TPUE would have been 14% higher without energy efficiency improvements.
  • Sri Lanka: TPUE would have been 42% higher without energy efficiency improvements.
• In Bangladesh, Bhutan, and Nepal, increases in energy intensity led to higher TPUE growth.
  • Bangladesh: 8% increase
  • Bhutan: 12% increase
  • Nepal: 46% increase

4. Energy Efficiency Gap and Saving Potential

• The report identifies the energy efficiency gap (EEG) and energy saving potential (ESP) in different sectors.
• A factor decomposition model is used to assess the contributions of various factors (energy intensity, fuel mix, GDP growth) to changes in energy use.
• No-regret technologies—those that offer significant energy savings with low or no additional cost—are highlighted as key options for reducing energy demand.

5. Energy Reduction Targets and Implications

• The study evaluates the implications of energy reduction targets on economic and environmental outcomes.
• It provides an analysis of cost and greenhouse gas (GHG) implications under different scenarios.
• The minimum share of energy reduction in passenger transport is outlined, with a focus on modal share variations.
• The Green Climate Fund (GCF) and other financial mechanisms are considered in the context of supporting energy efficiency initiatives.

6. Institutional Arrangements and Policies

• The report reviews institutional frameworks and policies related to energy efficiency and conservation in the five countries.
• It discusses the roles of national agencies and the existence of energy efficiency laws and regulations.
• Key policies include:
  • Energy Efficiency and Conservation Rules (EECR)
  • Energy Consumption Building Code (ECBC)
  • Standard and Labeling (S&L) programs
  • Perform Achieve and Trade (PAT) cycles
• Energy Efficiency Services Limited (EESL) and other organizations play a vital role in implementing these policies.

7. Regional Cooperation Opportunities

• The report emphasizes the importance of regional cooperation in promoting energy efficiency and conservation.
• Possible areas for collaboration include:
  • Sharing of best practices and technologies
  • Joint research and development
  • Harmonizing energy efficiency standards and regulations
  • Enhancing cross-border energy infrastructure
• The South Asia Subregional Economic Cooperation (SASEC) is highlighted as a platform for such collaboration.

Key Information

• Energy efficiency is a critical component of sustainable energy development and climate change mitigation.
• The AIM/Enduse model is used to analyze the energy consumption and efficiency trends across sectors.
• Energy efficiency improvements are essential to achieving low-carbon and climate-resilient development.
• Renewable energy and energy-efficient technologies are identified as key tools for reducing fossil fuel dependence and improving energy security.
• The report is available under a Creative Commons license, allowing for broader access and use of the findings.
• Regional cooperation can enhance the effectiveness of energy efficiency initiatives across South Asian countries.

Conclusion

This report provides a comprehensive overview of the current and future energy efficiency challenges and opportunities in South Asia. It highlights the importance of sector-specific energy efficiency measures, institutional reforms, and regional collaboration in achieving sustainable energy development. The findings are intended to support national energy planners, policy makers, and stakeholders in making informed decisions to reduce energy consumption, lower greenhouse gas emissions, and promote a more sustainable and efficient energy sector.
