renewable energy (RE) and electric vehicles (EVs) were to gain traction, the transportation and power generation industries might significantly cut their carbon emissions. Electric vehicles' widespread adoption may pave the way for renewable energy sources like solar and wind to become more integrated into power grids. In this article, we review the research on how renewable energy, the grid, and electric vehicles interact with one another. There is an analysis of well-known research methods and theoretical frameworks. We look at how EVs will affect the electricity system, the environment, and the economy. The topic of electric vehicle integration has been extensively researched. According to research, there is a lot of space for improvement in power system optimization in order to reduce the excess of renewable energy. A "vehicle to grid" (V2G) connection allows plug-in electric cars (PEVs) to connect to an already-established power grid. The electrical grid's efficiency may be enhanced by using the V2G idea. Overall productivity, consistency, and reliability will all see significant improvements. search terms Renewable energy sources, electric cars, embedded systems, and the Arduino uno
