# Analysis of Electric Vehicles with an Economic Perspective for the Future Electric Market
## 3 Renewable Energy Impact on Electric Mobility
The components required for this type of system are also very simple and easily available in the market. The ease of installation is reasonable and can be done quickly. The roof of the house is fitted with a solar panel to obtain maximum exposure to the sun to harvest solar energy. The generated energy is stored in the battery. An inverter is used to step-up the battery power to supply the charging for the electric vehicle. One of the problems that can be faced is shadowing over the panel from adjacent building and trees, which reduces the consistency of the power produced from the solar panel and affects its production. There are various research and techniques being followed and worked on to avoid this and come up with a solution to the problems addressed. As shown by the authors of [33; 39], a solar array is also used in many organizations to power up their business needs and provide the employees of their organization with the ability to charge their vehicles while they are at work. This will provide a good advantage to consumers: to charge their electric vehicles while they are working. This type of setup can be connected to the grid and provide power to different charging units to charge vehicles, or can not be connected to the grid. In this type of setup, a small microgrid within the organization is implemented for the power distribution and demand-side management of the charging stations [17; 30]. An overview of an organizational solar charging system is shown in Figure 8.

In an organization, it not only provides power to electric vehicles but also powers the needs of the different utility requirements in an organizational building. Hence, the greenhouse gas emissions are reduced from both the utility part and also from encouraging employees to use cleaner energy for commuting purposes [18; 31]. The grid system is used within the organization to manage the power requirements of the building, and is not connected to the large electrical grid of the area. The other type of energy source is the renewable energy connected to the smart grids and delivered to the electric vehicle charging units. Here, the other renewable energy sources are connected where the installation in all of the parts is not feasible. For example, wind turbines cannot be installed in every place, because wind energy harvesting requires the study of the wind flow in the area and whether it can deliver the power output. This is also applicable to hydroelectric power stations which are usually suited in mountain regions where the water current is high, which is ideal for harvesting energy from water. The energy generated from these sources has to be given to households and also to electric vehicle charging units, and hence the smart grids play an important role here. As shown by the authors of [32; 41], the main components of a smart grid include a generator, where the power is generated, and a consumer, where the power or energy is required. The grid forms an intermediate unit between the generator and consumer. Grid technology is improving day to day, with new algorithms and innovative techniques to determine the load at a particular date. Historical data, along with high processors and data analytics tools, help to predict the energy demand of a region at a particular hour in a particular month and day of the year [31; 32; 35]. This information and data help a smart grid to optimize the power flow, improve the power loss, and provide the required power to a household when needed. An overview of a smart grid system is given in Figure 9.  
Figure 8: Solar panel and charging system for household purposes. With an electric vehicle in a smart grid and the renewable energy connected to the grid with intelligent algorithms, the energy consumed by a battery for charging can also be made clean [41]. In smart grids, multiple sources contribute to the energy pool.
