With the increased number of electric vehicles in use, the energy consumption of electricity is slowly changing. This change in energy consumption of electricity is posing a challenge to the energy grid. Since a number of electric vehicles are normally charged at the same time in a region of the area, this has posed a serious challenge to the energy grid. Moreover, the energy grid is normally not producing enough energy from renewable sources of energy such as solar and wind energy. The aim of this paper is to discuss the impact that the charging of electric vehicles will have on the energy grid in a system that is based on renewable energy.
