Personal profile

An internationally renowned specialist of energy for international development with more than 30 years of experience in  global energy-environment issues, Professor Subhes specialises in energy, regulatory and environmental studies with a focus on developing country energy systems. He has extensively investigated energy access issues in South Asia and Sub-Saharan Africa since 2002 and has led award-winning research in this area through funded projects. He has also extensively worked on energy sector management issues such as energy sector regulation and restructuring in developing countries, and policy issues related to  energy security, climate change, natural resource utilisation and sustainable development. Subhes mainly focuses on applied, multi-disciplinary research that combines engineering, economics, and regulatory and environmental analysis. His research benefits from his past industry experience and his personal knowledge of working with developing country situations. Subhes’ research is supported by various modelling efforts, including end-use type long-range energy-environment system modelling, operations research and other decision support systems as well as regulatory and investment analysis tools. He provides advice on energy related issues on a regular basis.

He is the author of the best-selling book: Energy Economics: Concepts, Issues, Markets and Governance (Springer, 2011). He has also edited a number of other books particularly on rural electrification, mini-grids and energy in Asia. His research project OASYS South Asia received Green Gown Award for Community Innovation at the national and international categories in 2015.

Research interests/expertise

Subhes’ interest in energy research includes the following:

<start_a> a)   Energy Access and Sustainable living in developing countries

  • Research to identify ways of supplying energy to the bottom billion and supporting sustainable living in developing countries. 
  • Strategies and enabling conditions for the provision of clean and affordable energy for the poor.
  • Sustainability analysis and development impacts of energy interventions for rural development.
  • Vulnerability and mitigation of climate and security of energy supply in developing countries and their impact on sustainable development. 

<start_b> b)   Policy issues

  • Low carbon energy pathways in developing countries - covering resource-rich and resource poor countries.
  • Energy pricing, taxation and subsidies in developing countries for supporting sustainable energy in developing countries
  • Policies for fossil fuels and renewable energies.

 c)   Energy modelling

  • Modelling energy demand in developing countries: Energy Demand analysis and demand management - in industry, transport and residential sectors.
  • Extension of the index decomposition methodology – This is an area of was applied to an analysis of climate change analysis
  • Electricity system expansion studies for conventional studies and to capture vulnerability and energy security aspects.
