AbstractDespite enormous challenges in accessing sustainable energy supplies and advanced energy technologies, Ethiopia has one of the world's fastest growing economies. The development of renewable energy technology and the building of a green legacy in the country are being prioritized. The total installed capacity for electricity generation in Ethiopia is 4324.3 MW as on October, 2018. Renewable energy accounts for 96.5% of total generation; however, despite the county's enormous biomass energy potential, only 0.58% of power is generated using biomass. Ethiopia has surplus woody biomass, crop residue and animal dung resources which comprise about 141.8 million metric tons of biomass availability per year. At present the exploited potential is about 71.9 million metric tons per year. This review paper provides an in-depth assessment of Ethiopia's biomass energy availability, potential, challenges, and prospects. The findings show that, despite Ethiopia's vast biomass resource potential, the current use of modern energy from biomass is still limited. As a result, this study supports the use of biomass-based alternative energy sources without having a negative impact on the socioeconomic system or jeopardizing food security or the environment. This finding also shows the challenges, opportunities and possible solutions to tackle the problem to expand alternative energy sources. The most effective techniques for producing and utilizing alternate energy sources were also explored. Moreover, some perspectives are given based on the challenges of using efficient energy production and sustainable uses of biomass energy in Ethiopia as it could be also implemented in other developing countries. We believe that the information in this review will shed light on the current and future prospects of biomass energy deployment in Ethiopia.

The food eaten by people in their daily life must be preserved in good conditions. Therefore and for a better environment protection, the classical refrigeration systems that use a refrigerant had been removed and a solar thermo-electric cooler based on alternative energy sources was adopted. The solar energy was used in order to produce electrical energy, while the thermo-electric energy was responsible for the thermal transfer between the cooling room and the TEC modules, significantly reducing the temperature of the cold room and food products, respectively. The operation of the solar refrigerator was observed during the time of cooling one kilogram of pork meat and one litre of milk. In the case of cooling meat, the minimum temperature achieved was 1.8 ºC, respective 0.2 ºC when refrigerating milk. Considering the food refrigeration rated optimum temperature (0-4 ºC), the analysis of the experimental results highlighted the possibility of preserving meat and liquids in proper conditions by using a solar thermo-electric refrigerator, which is an ecological equipment with the pollution rate extremely low, almost null.

The problems of energy, environment protection and ecology play a major role in the development of economy strategy in any country. Most of the traditional power stations operating on organic fuels have a negative impact on the environment. Furthermore, there is a depletion of natural resources due to human activities. One of the ways to solve the problem of environmentally friendly energy production is to use alternative sources of energy. Based on the foregoing, the development of the strategy for the development of traditional and alternative energy must consider environmental and economic factors in a specific country. In the present work it was evaluated the environmental and economic efficiency of application of traditional and alternative energy with regard to the conditions of the Islamic Republic of Iran. The program packages RETScreen which is one of the most effective tools to accomplish the task was used. Calculations of cumulative cash flow from the operation of power plants using different types of primary energy are carried out using models of package RETScreen for assessing the input efficiency of various types of energy sources aiming to cover the intending growth in electricity demands and the environmental assessment with reference to different countries. The results of the study showed that the planning prospects of the development of energy systems in relation to the Islamic Republic of Iran to cover the expected growth in electricity demands it is advisable to use the alternative energy sources, and, first of all, the generating capacity based on solar and wind energy.
