This study investigates the performance of a solar ejector cooling system under both on-design and off-design operating conditions, focusing on the case study area of Addis Ababa, Ethiopia. . Ethiopia is poised to become a global model for renewable energy transition, harnessing its abundant solar resources to deliver affordable and reliable electricity while driving sustainable development. Data crucial to the analysis were gathered from the Ethiopian National Meteorology Agency (ENMA) over six. . Ethiopia generates most of its electricity from renewable energy, mainly hydropower. The country is strategically expanding its energy sector, aiming for a more diverse and resilient mix. Among these, solar energy emerges as a beacon of hope, poised to transform Ethiopia's energy landscape and drive socioeconomic development. Implemented with the Development Bank of Ethiopia and international partners, the program focuses on solar home systems and mini-grids. It aims to. .

V2X (Vehicle-to-Everything) technology enables electric vehicles to interact with external devices or the power grid, ensuring efficient use of electricity. Today, we will explore the four main external power supply functions: V2L, V2V, V2H, and V2G. . Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site's building infrastructure. A bidirectional EV can receive energy (charge) from electric vehicle supply equipment (EVSE) and provide energy to an external. . In this study, to investigate the energy storage characteristics of EVs, we first established a single EV virtual energy storage (EVVES) model based on the energy storage characteristics of EVs. V2L allows electric vehicles to supply power to. .
