A Handbook for Measuring Energy Access in Developing Countries

Impact evaluation has gained recognition over the last decade as an essential component of project development. Impact evaluation details how and to what extent policies and project interventions contribute to socioeconomic welfare gains or losses for society. Such evaluations are also important for identifying key lessons for future policies and investments. In the case of modern energy access, the measurement of costs is fairly straightforward. However, measuring the benefits to society is more difficult and might involve implementing national or regional surveys. Past efforts have often underestimated the complex linkages of benefits produced by programs involved in providing electricity and clean cooking energy to rural and other populations without access to modern energy services. Thus, it has often been difficult to balance the costs of program investments in energy access vis-à-vis their benefits.

This study’s main objective is to develop a practical method by which to measure the benefits of rural energy, including both electricity and clean cooking. The methods reviewed in this report involve both formal and informal techniques of data collection, including quantitative and qualitative methods of analysis. The research pays attention to such concepts as quality of life, effects on education, and other key components of social development; that is, it tackles those benefits of modern energy access that traditionally have been difficult to measure, as well as the easier-to-measure benefits.

Energy Access and Poverty in Latin America, 2018

Ecofogon Stove Used in Small Business in Nicaragua
Recently I helped complete a new report on energy access in Latin American the the Caribbean area. The title of the report is Meeting Challenges, Progress: The Benefits of Sustainable Energy Access in Latin America and the Carribean. Making This new report was produced by a joint effort between the Inter-American Development Bank and the United Natoins Development Programme.

Energy access is an essential prerequisite for economic, social, and human development. The 2015 United Nations Sustainable Development Goals (SDGs) explicitly recognized affordable and clean energy as a key factor in development, alongside education and poverty alleviation. The UN Sustainable Energy for All initiative (SEforALL) mobilizes international donors, countries, and the private sector to help people in developing countries gain access to modern energy services.

To assist in support of sustainable energy for all goals, I was recently involved in producing this joint study of the Inter-American Development Bank (IDB) and the United Nations Development Programme (UNDP). it provides a comprehensive review of energy poverty policies and programs in Latin America and the Caribbean. This report measures the progress and impact of energy-access programs and also documents the experience of successful projects. This study reviews cutting-edge methodologies to assist in program design, shares of experiences of successful programs and develops a vision for reaching sustainable energy for all in the LAC region.

With electricity coverage at more than 96 percent, Latin America and the Caribbean (LAC) is close to becoming the world’s first developing region to achieve universal access to electricity. Despite recent progress, within LAC there are still substantial pockets of energy poverty. Approximately 21.8 million people are without electricity access. More than 80 million people rely on firewood and charcoal for cooking that is burned in fuel-inefficient, primitive stoves. These traditional cooking technologies emit a significant amount of indoor air pollution (IAP), which has been linked to respiratory illnesses and adverse environmental impacts. Thus, in addition to promoting electricity, energy access programs also might give priority to the promotion of cleaner methods cooking by making available better stoves and cleaner burning fuels at reasonable costs.

The report also explores ways to measure energy poverty and monitor energy access in developing countries. The accuracy and effectiveness of tools such as the IEA’s household energy data efforts and the Global Tracking Framework depend on collecting information through standardized national surveys. Approaches to measuring energy poverty and monitor energy access have increasingly focused on the provision of energy services such as lighting, space conditioning and cooking.

The transition from low-quality energy services to more modern forms can be accomplished in different ways. As households in developing countries adopt electricity and clean methods of cooking, they benefit from higher quality, lower cost and convenient to use appliances. However, measuring the societal and developmental benefits of energy investments--though difficult--is important.

Two basic approaches have evolved over the years to measure the benefits of energy access: (i) consumer surplus and (ii) regression-based techniques. The consumer surplus approach evaluates the economic benefits of energy services by measuring increased demand resulting from lower costs of such energy end uses such as lighting, radio and television. When possible, rigorous impact evaluation techniques based on multivariate models can be used to more directly measure the socioeconomic benefits associated with energy access and modern energy services including higher income and improved education.

In recent years, new approaches for meeting the requirements of modern and sustainable energy services have emerged. Due to technical and market changes, new types of equipment have become available for providing energy services to rural areas. In LAC, three basic models have been developed to provide rural populations with electricity service: (i) main grid extension, (ii) community networks, and (iii) individual home-based systems (including clean cookstoves).

The level of investments necessary to achieve the 2030 SDG target for expanded electricity access for all will be quite high. Reaching the universal access goal will require developing innovative partnerships between the public and private sectors. All three models benefit from favorable institutional and policy conditions, including funding mechanisms like subsidies and small-scale finance. In addition, various kinds of specialized energy funds have been developed to promote energy access. The new focus on remote areas may require some rethinking of the institutions and subsidies necessary to promote decentralized electrification programs.

A multifaceted approach to solving rural energy problems is essential for bringing remote or underserved populations into the twenty-first century. New electricity technologies and innovative business models are emerging to deal with the poorest and most remote populations in LAC. Such innovation needs to expand to include more initiatives for better cooking fuels and clean-burning, fuel-efficient biomass stoves. Proper impact evaluation of energy access interventions is needed to justify program subsidies and to better target such programs to poor and remote populations.

Over the past two decades, the LAC region has made remarkable progress toward providing sustainable, modern energy for all. Going forward, the challenge is to provide electricity and clean cooking solutions to the region’s most remote, vulnerable and poorest populations.

From Traditional to Modern Stoves: A Chronology of Development


By Doug Barnes

India Traditional Stove: Credit C. Carnemark
Recently I participated in a very interesting workshop at Yale University. The workshop was called The Adoption Gap: Design, Development and Diusion of Household Energy Technologies. The focus of the conference was to examine why improved biomass cooking stoves have not achieved widespread adoption even after over 25 years of promotion. Many of the presentations were very innovative. Included among the speakers was Rema Hanna, who is the author of the controversial study Up in Smoke. She talked about her well designed stove impact assessment. Unfortunately, the stove being evaluated was from India's legacy mud stove program, some of which are still being promoted. Hanna made the valid point that many current programs are still supporting such stoves. While this is true, today there are many  better designed stoves compared to those from the 1990s (see commentary on the paper). Unfortunately, public monitoring and evaluation studies of these new stoves are still fairly sparse. The presentations from the conference are not yet available on line, but I will update this blog once they become available.
Fortunately or unfortunately, I am one of a small number of people that have been involved in improved stove development for almost its entire history. I say fortunately because it has been a very interesting to observe the evolution of the programs over the years. I say unfortunately, because even today with the many innovations taking place, most poor households in developing countries still use open fires or primitive stoves for cooking.  Also, in many countries well meaning non-governmental organizations are still promoting the stoves designed in the 1990s.
I prepared a presentation for the conferences with the title, Improved Stoves:  What Have We Learned, How Do We Move Forward? The ideas for this presentation were taken from my recent book Cleaner Hearths, Better Homes: New Stoves for India and the Developing World. For those interested, a free digital copy of the book is available, or for those more interested in print, copies can be purchased online. The book describes the positive and negative aspects of India's legacy improved stove program that was abandoned in 2002. This legacy program now is universally criticized, but most people really don't understand the pros and cons of the old program. Some aspects of the legacy stove program were quite innovative, including working with NGOs, including women's groups, assigning technical agencies to evaluate design issues, and developing commercialization strategies. Many of these innovations are relevant for the promotion and sale of improved stoves today. 
As part of my presentation, I had one slide on the development of stove programs. For those just now becoming interested in the new stoves, this slide provides a historical overview of the 25 year history of improved stoves.  The text below the break is from a glossy insert in the center of Cleaner Hearths: Better Homes that was published in 2012. The rest of the book is based on empirical findings from short questionnaires and focus discussion groups carried out at the very end of India's program. The book takes a more objective approach identifying both what went wrong and also positive contributions of the program for people in India. Anyway, continue after the break to read my short history of improved stoves.
