Grape is one of the world's largest fruit crops with approximately 67.5 million tonnes produced each year and energy is an important element in modern grape productions as it heavily depends on fossil and other energy resources. Efficient use of these energies is a necessary step toward reducing environmental hazards, preventing destruction of natural resources and ensuring agricultural sustainability. Hence, identifying excessive use of energy as well as reducing energy resources is the main focus of this paper to optimize energy consumption in grape production.

We use three rounds of a rich panel data set to investigate the determinants of household fuel choice and energy transition in urban Ethiopia. We observe that energy transition did not occur following economic growth in Ethiopia during the past decade.

In this study, we assess the economy-wide effects of biofuel investment in Ethiopia, with a focus on the external sector. The Government of Ethiopia has been revising its energy policy to switch from imported fossil oil to domestically produced biofuels, partly in response to climate change and partly in response to rising world oil prices, which leave oil-importing countries such as Ethiopia vulnerable to external oil price shocks.

As a result of many years of deforestation, fuelwood scarcity is a critical problem in Ethiopia. The Ethiopian government encouraged afforestation and tree growing at both the community and household levels as a policy to stem deforestation and degradation of agricultural lands. The rationale underlying the tree growing strategy is that some significant part of whatever is planted will be used as fuelwood, thereby reducing the demand for wood from native forestlands and use of crop residues and animal dung needed for soil improvement.

This study examines the relationship between property rights, defined by land tenure security and the strength of local-level institutions, and household's preferences for fuelwood source. A multinomial regression model applied to survey data collected in rural Ethiopia underpins the analysis. Results from the discrete choice model indicate that active local-level institutions increase household dependency on open access forests, while land security reduces open access forest dependence.

Previous studies on improved cookstove adoption in developing countries use cross-sectional data, which makes it difficult to control for unobserved heterogeneity and investigate what happens to adoption over time.

In response to global opportunities and domestic challenges, Ethiopia is revising its energy policy to switch from high-cost imported fossil fuel to domestically produced biofuels. Currently, there are biofuel investment activities in different parts of the country to produce ethanol and biodiesel. However, there is no rigorous empirical study to assess impacts of such investments.

We analyze the interaction between a reliable source of electricity production and intermittentsources such as wind or solar power. We first characterize the optimal energy mix, emphasizing the availability of the intermittentsource as a major parameter for the optimal investment in capacity.
