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.

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.

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.

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.

    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.

    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

    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.

    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.

      Evaluating Rural Electrification: Illustrating Research Gaps with the Case of Bhutan

      Electrification, especially rural electrification (RE), is a core component of the Sustainable Development Goals and a major focal point of the global development community. Despite this focus, more than one billion people worldwide do not have access to electricity, and electrification growth rates are not keeping pace with population growth. In this paper, we posit that lack of progress is partly driven by a misalignment between academic research and energy planners’ and policy makers’ needs.

        Impacts of rural electrification revisited – the African context

        The investment requirements to achieve the United Nations’ universal electricity access goal by 2030 are estimated at 640 billion USD. The assumption underlying this goal is that electrification contributes to poverty alleviation in many regards. In recent years, a body of literature has emerged that widely confirms this positive poverty impact assumption. Most of these studies, however, are based on data from Asia and Latin America. This paper challenges the transferability of impact findings in the literature to the African context.

            Explaining environmental health behaviors: Evidence from rural India on the influence of discount rates

            The authors examine whether high personal discount rates help explain why and which households in developing countries under-invest in seemingly low-cost options to avert environmental health threats, including bednets, clean cooking fuels, individual household latrines, water treatment and handwashing. First, the authors elicit personal discount rates by combining a simple randomized experiment with detailed surveys of over 10,000 rural households in Maharashtra, India. Personal discount rates are lower for women, for better-off households, and for households who can access formal credit.
