Solar energy has the highest power density among all the listed (Cao & Li, 2017) WSNs energy harvesting sources.
With its target of becoming a middle-income country by 2025, Ethiopia has set ambitious targets in its Growth Transformation Plan (GTP) II, such as increasing power generation capacity from 4.18
Among energy storage technologies, batteries have a better ability to disperse renewable energy, especially photovoltaic system and wind energy, due to their high energy density. 2 Literature Review There is a great deal of research on the location of energy sources today, not only for distributed energy sources and renewable energy sources
Water-borne diseases pose a significant challenge to the sustainability of healthcare in developing countries like Ethiopia. While wireless sensor networks (WSN) address many environmental and societal issues through various applications, energy harvesting approaches extend the network''s life. The paper describes a water quality monitoring system
Solar energy is one of the most favorable renewable energy sources and has undergone significant development in the past few years. This paper investigates a novel concept of harvesting the
In conclusion, this Outcome Harvesting evaluation revealed many ways in which the HC3 Ethiopia project influenced change among individuals, organizations and systems working on SBCC in Ethiopia— change that continues to manifest throughout the FMOH and the Federal HIV/AIDS Prevention and Control Office (HAPCO), HC3 Ethiopia''s primary audiences.
If more energy is produced by the sources and battery SoC is also greater than 0.8, surplus energy is utilized to produce H 2 case the main supplies are incapable of assuring the load requisite, immediately battery is turned active, and it supplies the load along with the other sources till it reaches lower limit of SoC and then control is transferred to fuel cell.

The Internet of Things paradigm considers the deployment in the environment of a profusion of heterogeneous sensor nodes, connected in a complex network, and autonomously powered. Energy harvesting is the common proposed solution to supply such sensors,
So, reducing energy consumption can inevitably help to reduce emissions. However, some energy consumption is essential to human wellbeing and rising living standards. Energy intensity can therefore be a useful metric to monitor. Energy intensity measures the amount of energy consumed per unit of gross domestic product.
In Kobo Ethiopia, the outputs from flood diversion (spate irrigation) are giving confidence to the farming community. Traditional flood harvesting systems in Kobo are that the technique is fully managed by the

Water Supply. Rainwater harvesting (RWH) is a novel way for developing countries to construct and maintain long-term water supply systems. As a result, this review article draws on actual findings and lessons learned from various places in Ethiopia to assess the country's achievements and opportunities when it comes to RWH, as well as to guide future alternatives
With funding from the The Ceil and Michael E. Pulitzer Foundation, the Columbia Water Center designed an innovative rainwater harvesting system designed to catch and store water in the landscape. The design includes an interconnected network of five microdams along with an infiltration trench system to recharge underground aquifers.
p> Background: Natural pasture is an essential source of livestock feed worldwide, particularly in Ethiopia. Though pastureland coverage and management practices are changing over time, studies
The main concern is whether energy harvesting systems can produce enough power considering the energy sources'' intermittency. Also, the implementation costs and production of low energy harvesting systems are important challenges that hamper technology development [40]. Therefore, more research is necessary to improve technology adoption [41].
energy in Ethiopia is relatively low, as little as 16 % (2005), while the average access rate of Sub-Sahara Africa is 26% (figure 1). The access to energy is gradually improving to reach There are two systems of transmission of electricity; one is called ICS (Inter-Connected System) and the other SCS (Self-Contained System). The former is
Rainwater harvesting systems can reduce dependence on the mains water supply, relieving pressure on often overused water resources. 2.1. Rainwater harvesting in Ethiopia Ethiopia is one of the largest countries in Africa (a land area of 1.13 million km2).
In Kobo Ethiopia, the outputs from flood diversion (spate irrigation) are giving confidence to the farming community. Traditional flood harvesting systems in Kobo are that the technique is fully managed by the farmers who know how to implementthemselves with their own resources (Nigigi & Stephen, Citation 2003; Tesfaye, Citation 2003).
Energy in Ethiopia includes energy and electricity production, consumption, transport, exportation, and importation in the country of Ethiopia . Ethiopia's energy sector is crucial for its development, with wood being a primary energy source, leading to deforestation challenges.
In light of this, the Government of Ethiopia's strategic priorities in the energy sector are: universal electrification access, energy efficiency improvement, decentralized off-grid power generation through the development of renewable energy technologies, and exporting electricity to neighboring countries.
Predicted by Swanson's law, the levelized costs for photovoltaics have plunged to levels just above that of hydropower and wind power. Ethiopia aims to diversify its electricity generation capabilities by investing into an energy mix, of which photovoltaics will be a part.
The selection of least-cost technologies to supply energy is crucial for Ethiopia to meet the projected energy demand (specifically electricity) if the country is to achieve universal electricity access.
The country focuses on the production of electricity from a mix of cheap and clean renewable primary energy sources like hydropower or wind power. Ethiopia has a total identified economically feasible potential of 45 GW of hydropower and 1,350 GW of wind power.
All in all, energy consumption in Ethiopia continues to be dominated by the residential sector which accounts for 95% in 1990 and 88% in 2018 . During the same period, the shares of industry and transport sectors grew, respectively, from 1.3 to 3.7%, and from 1.8 to 5.5% .
