Social Learning, Gender, and Willingness-to-pay for Solar Lanterns

This project is an attempt to better understand the effects of social networks on the diffusion and adoption of new technologies. In particular, we investigate if having friends or relative that had a chance to experience solar lanterns for their personal use increases an individual's willingness to pay for a solar lantern.


Improving energy efficiency in Costa Rican households: the effect of pecuniary and non-pecuniary incentives in shaping the timing of consumption

Reducing a country´s dependence on fossil fuels is central to mitigate climate change and to promote the use of cheaper energy sources. In Costa Rica most energy is generated using hydro-electrical plants, however the fact that energy consumption is lumped in peak hours forces the use of fossil fuel (mostly diesel and bunker) based electricity generation.


Economy Wide Impact of the Electricity Sector in Ethiopia

As a result of growing demand for electricity and recognizing the critical role played by the energy sector in the economic growth and development process, the Government of Ethiopia has already embarked on large scale hydroelectricity projects in view of developing renewable and sustainable energy sources. The goal of this project is to contribute to the fulfillment of these efforts in expanding modern energy access and reducing energy poverty through accelerating the growth of the economy.


Household energy conservation in Kenya

Kenya is a rapidly growing country, with energy demands increasing annually. Over-reliance on biomass energy within households has resulted in adverse environmental effects. Forest cover has fallen to 6%, and as a result, water levels in rivers and dams have also fallen leading to an inconsistent electricity supply. This study seeks to explore energy conservation in Kenya using quantitative methods and an established data set.


Adoption of solar energy in Kenya

Although African countries’ GHG emissions are comparatively low, the effects of climate change are still widespread and a reduction in emissions is crucial. In a bid to reduce emissions, there has been a shift towards renewable energy such as wind, hydro-electric and of course, solar energy in Kenya. This study will explore adoption of solar technology in Kenyan households using quantitative methods.


Profitability and Economy-wide Impact of Biofuel Investments in Ethiopia

Given the volatility of world oil prices and the recent all time high, which increased their popularity, bio-fuels have received a great deal of attention globally. The central questions of interest include whether this will have a positive or a negative impact on smallholder farmers and people living in rural areas, as more agricultural land will be used for biofuels production? And what is the effect of these large scale biofuels investments on growth and poverty reduction endeavors of poor countries?


Urban energy transition and technology adoption: the case of Tigrai, northern Ethiopia

Deforestation in Ethiopia has resulted in growing fuel scarcity and higher firewood prices in urban centers. Urban centers have long been dependent on the rural hinterlands for their fuel. The use of biofuels of rural origin covers about 90% of the urban fuel use. The dependence of urban centers on their rural hinterlands has aggravated the deforestation. One response to reducing the pressure of urban centers on their rural hinterlands could be through substitutions between or switching from one fuel to another, i.e., through energy transition. For example, through substituting away or switching from fuelwood to electricity. Electricity as cooking fuel is cleaner and do not cause deforestation.


The Short-Run Subsidies, Take-Up, and Long-Run Demand for Off-Grid Solar for the Poor: Evidence from Large-Scale Randomized Trials in Rwanda

Over a billion people lack access to electricity, instead relying on kerosene and other dirty lighting sources, while grid expansion is not expected to keep pace with population growth. Moreover, pneumonia is the leading cause of death for under-fives in the world and kerosene smoke is a significant risk factor. For-profit distribution of low-cost solar LEDs has been suggested as a solution, but adoption remains low, especially by the poorest.


Competition and Gender in the Lab vs. Field: Experiments with Off-Grid Renewable Energy Entrepreneurs in Rural Rwanda

Applications of lab experiments to real-world phenomena are limited. We fill the gap by examining how gender attitudes and performance under competitive situations in the lab reflect microenterprise outcomes in the renewable energy sector of Rwanda – a country with progressive gender policies despite its traditional patriarchal setup. We use the standard Niederle and Vesterlund (2007) experimental design in addition to a unique dataset from off-grid microenterprises, managed by entrepreneurs who have been working in mixed and single-sex teams since 2016.


Magnitude and Distribution of Electricity and Water Subsidies for Households in Addis Ababa, Ethiopia

In Addis Ababa, an increasing block tariff has been used to calculate households’ monthly bills for electricity and water services. This study estimates the magnitudes of the combined water and electricity subsidies received by households with private connections to the electricity grid and piped water network in 2016, and it evaluates the distribution of these subsidies among wealth groups.


Using electricity prices to curb industrial pollution

In this study, we show that changes in electricity prices in China have significant environmental consequences through its effect on industrial pollution emissions concentrations. To investigate this relationship, we pair a novel dataset of hourly smokestack-level pollutant emissions of industrial plants in Anhui, China with changes in hourly electricity prices. Using a difference-in-differences (DID) regression model, we find that pollution emissions from these plants have an inverse relationship with electricity prices.


Temperature effects on mortality and household adaptation: Evidence from China

This paper examines the effects of extreme temperatures on mortality rates, using random year-to-year variation in temperature based on county-level panel data from China. The analysis finds a robust, U-shaped relationship between temperature and mortality rates, indicating that extremely cold or hot temperatures lead to excess deaths. The heat-related (cold-related) effect is 3.5 times (3.2 times) as large as previous findings that used U.S. data, and it is especially large for the elderly population, mainly due to excess deaths caused by cardiovascular diseases. Applying these results to climate change predictions from Hadley Centre Global Environmental Model shows that by 2061–2080 the annual mortality rate is likely to increase by 14.2% if global greenhouse gas emissions continue to rise throughout the 21st century, the estimated health cost of which is around 0.98 trillion Chinese Yuan per year.


Costos Económicos de las Externalidades Ambientales del fracking: un análisis de metaregresión y algunas implicaciones para Colombia

La cuantificación monetaria de las externalidades ambientales derivadas de la explotación de hidrocarburos no convencionales que utiliza la técnica de fracturación hidráulica o fracking muestra una alta variabilidad pues sus costos no están unívocamente determinados.

Forward contracts in electricity markets and capacity investment: A simulation study

This simulation study analyzes the effect of the introduction of forward markets to mitigate cyclical price behavior in electricity markets from a dynamic extended Cobweb model. We pay particular attention to the effect of lags in investment decisions and the effect of not fully replacing retired capacity in electricity markets. In line with previous research, the introduction of forward markets decreases price variability in comparison to a spot market.


The Shale Gas Boom in the US: Productivity Shocks and Price Responsiveness

Many studies have been focusing on the impact of the shale gas boom on our society, but the reverse relationship is not well documented. The objective of this paper is to examine the impact of oil and gas prices on shale gas drilling activities. We analyze the well-level production data from all major producing shale gas plays in the United States (US) and identify a major productivity shock in 2009. We then estimate the price elasticity of shale gas drilling using the econometric methods. Our results show that the oil price elasticity increases from insignificant in the pilot stage (2000–2008) to 1.1 (significant) in the expansion stage (2009–2016), and the gas price elasticity increases from insignificant in the pilot stage to 0.6 (significant) in the expansion stage.


The consequences of increasing block tariffs on the distribution of residential electricity subsidies in Addis Ababa, Ethiopia

This study evaluates the distribution of electricity subsidies to residential customers in Addis Ababa, Ethiopia in 2016 that results from the current increasing block tariff (IBT) structure. Customer billing data supplied by the electricity utility were matched with socioeconomic information collected from a survey of 987 households, and used with a utility-specific estimate of the costs of electricity service to estimate household-specific subsidies.


Does Urbanization Increase Residential Energy Use? Evidence from the Chinese Residential Energy Consumption Survey 2012

China’s rapid urbanization and increasing energy use are accompanied by deteriorating environmental quality. Understanding the structure of energy use is necessary to address these environmental effects. We investigate how urbanization affects residential energy use, using data from the Chinese Residential Energy Consumption Survey 2012 (CRECS 2012) to compare the energy consumption of urban and rural households and identify the factors influencing the differences.


    Assessment of Local content and local community participation policies

    Most of the current developmental projects in Tanzania on natural resources has been established basing on their national/macro-economic impacts and environmental impacts with little attention to the understanding of the nature/ways of lives of the local community. We understand that lately there has been a movement of resource rich countries to incorporate local content component in their policies so that local people can really benefit from the sector.


    The power of nudging: Using feedback, competition and responsibility assignment to save electricity in a non-residential setting

    We use behavioural insights to design nudges, leveraging social comparison and assignment of responsibility, aimed at reducing electricity consumption in a large provincial government office building with 24 floors, a total of 1008 occupants. Results from a randomized control trial show that floors participating in a treatment with inter-floor competitions and tips reduced energy consumption by 9%, while those that also included floor-wise “energy advocates” reduced energy consumption by 14% over a period of 5 months.


    Cost of Power Outages for Manufacturing Firms in Ethiopia:A Stated Preference Study

    Having a reliable supply of electricity is essential for the operation of any firm. In most developing countries, however, electricity supply is highly unreliable. In this study, we estimate the cost of power outages for micro-, small-, and medium-sized enterprises in Addis Ababa, Ethiopia, using a stated preference survey. We find that the willingness to pay, and thus the cost of power outages, is substantial. The estimated willingness to pay for a reduction of one power outage corresponds to a tariff increase of 16 percent.


    Uncertainty and the long-term adequacy of supply: Simulations of capacity mechanisms in electricity markets

    Deregulation in electricity markets has changed the conditions for maintaining long-term adequacy of supply. Particularly in the last decade, security of supply has become a major issue for policymakers due to a number of changes in technology, especially the introduction of renewables, where regulators have introduced capacity mechanisms. In this paper, we focus on the use of two different capacity mechanisms: procurement for long-term strategic reserves contracting, and centralized auctioning for capacity contracts.


    The prospects for small Hydropower in Colombia

    Small hydropower (SHP) has existed for more than a century in Colombia, and is gaining reserved interest as an option to mitigating climate change. In this paper we investigate the prospects for SHP in Colombia based on an analysis of economies-of-scale and learning-by-doing effects. We created an inventory of SHP plants realized in Colombia between 1900 and 2013, and focused on grid-connected SHP stations only. In the economies-of-scale part of our analysis we considered all SHP plants with a capacity lower than 20 MW.


    Spatial Distribution of Coal-Fired Power Plants in China

    Coal has fueled China's rapid growth in recent decades, but it also severely pollutes the air and causes many health issues. The magnitude of the health damage caused by air pollution depends on the location of emission sources. In this paper, we look into the spatial distribution of coal-fired power plants, which are the major emission sources in China, and investigate the determining factors behind the distribution.


    Are renewable energy policies climate friendly? The role of capacity constraints and market power

    This paper studies the impacts of renewable energy support policies on energy prices, fossil fuel supply and thus carbon emissions from fossil fuels. Such supports are climate friendly if the renewables are already competitive against fossil fuels. But if the renewables are not yet competitive, the climate change impacts are often ambiguous and are sensitive to capacity constraints of renewables production and to the fossil fuel market structure. If the renewables


    Determinants of enterprises use of energy efficient technologies: Evidence from urban Ethiopia

    This paper examines the determinants of Micro, Small and Medium Enterprises’ adoption of energy efficiency practices and technologies, using cross-sectional data of 8174 randomly selected enterprises from ten major urban areas of Ethiopia. For identification, the study relys on a generalized ordered probit model. The findings reveal that, as the size of the enterprise becomes larger, it is more likely the enterprise will undertake energy efficient practices and technologies.


    Unveiling the Energy Saving Role of Banking Performance in Sub-Sahara Africa

    This article examines the effect of commercial bank performance on an indicator of energy efficiency (i.e. energy intensity) while controlling for the mediating effect of political institution. To achieve this goal, the study develops a theoretical model based on the neoclassical theory of the firm that links energy efficiency to bank sector development, and a unique bank-based data by Andrianova et al. (2015) for 43 Sub-Saharan African countries from 1998 to 2012.


    Land for food or power? Risk governance of dams and family farms in Southwest Ethiopia

    This study use the concepts of riskscapes and risk governance to analyze the tensions between land use for food (farms) and energy (dams) in South West Ethiopia. It analyzes the linkage between risk perception, risk assessment and risk management for local and non-local actors. The study distinguish, after empirical analysis, as main riskscapes the riskscapes of landlessness, food and energy insecurity and siltation.


    Profitability of Bioethanol production: The Case of Ethiopia

    This research investigates the profitability of bioethanol production in Africa, taking Ethiopia as a case in point, and suggests an oil price threshold beyond which biofuels may be profitable. Specifically, the study analyzes the viability of producing bioethanol from molasses in the context of Ethiopia, using data from a biofuels investment survey by EEPFE/EDRI in 2010. The study draw on investment theory as underlying conceptual framework and employ unit cost analysis for the empirical analysis.


    The impact of microhydroelectricity on household welfare indicators

    The use of small-scale off-grid renewable energy for rural electrification is now seen as part of the sustainable energy solutions. The expectation from such small-scale investment is that it can meet the basic energy needs of a household and subsequently improve someaspects of household welfare. However, these stated benefits remain largely hypothetical because there are data and methodological challenges in existing literature attempting to isolate such impact.


    Driving forces for households' adoption of improved cooking stoves in rural Tanzania

    With increasingly improved cooking stoves (ICS) that aim to reduce fuelwood consumption by forest-dependent households, more evidence of what drives households to adopt ICS is needed. Using data from a representative sample (N=271) of households in a rural part of eastern Tanzania, we estimated a mixed logit model to take into account the limitations of the standard multinomial logit model and relaxed the restrictive assumption of the conditional logit model.


    Fuel savings, cooking time and user satisfaction with improved biomass cookstoves

    Continued high reliance on traditional biomass fuels and stoves in developing countries gives rise to several human health, environmental, and livelihood issues. However solid data on the performance of improved biomass cooking stoves remains scarce. This paper provides controlled cooking test (CCT) evidence on fuel savings from a promising improved biomass cooking stove in Ethiopia. The stove is called Mirt(meaning “best” in Amharic), and is used to bake injera, the staple food in much of Ethiopia. Injera preparation accounts for about half the primary energy consumed in the country.


    Determinants of Enterprises’ Use of Energy Efficient Technologies

    This study conducted a cross-sectional survey of 8174 micro, small and medium enterprises from ten major urban areas in Ethiopia to study the determinants of the enterprises’ adoption of energy efficiency practices and technologies. For identification, we rely on a generalized ordered probit model. The findings reveal that, as the size of the enterprise becomes larger, it is more likely the enterprise will undertake energy efficient practices and technologies.


    The Impact of Micro Hydroelectricity on Household Welfare Indicators

    The use of small-scale off-grid renewable energy for rural electrification is now seen as one sustainable energy solution. The expectations from such small-scale investment include meeting basic household energy needs and thereby improving some aspects of household welfare. However, these stated benefits remain largely hypothetical because there are data and methodological challenges in existing literature attempting to isolate such impacts. This paper uses field data from micro hydro schemes in Kenya and a propensity score matching technique to demonstrate such an impact.


    Collective forest tenure reform and household energy consumption: A case study in Yunnan Province, China

    The recent Collective Forest Tenure Reform in China has started the process of devolving forest management rights from village collectives to households since 2003. In this paper, we study the impact of the reform on rural energy consumption. Devolving forest tenure improves farmers' access to forest products on their newly acquired forestland, and is therefore expected to increase farmers' fuelwood consumption. The reform also allows farmers to adopt some revenue-enhancing forest technologies which may lead to energy switching in farmer households.
