# Efficient Management of Power Losses from Renewable Sources Using Removable E.V. Batteries
## 6 Conclusions  
The strategy that can efficiently manage losses resulting from generating electricity with renewable sources when demand cannot take over the entire supply involves storing the surplus of renewable energy. Given that the integration of increasing quantities requires an oversizing of storage capacity, which is currently not economically efficient, an innovative solution is needed [8; 9; 17; 62]. Such an innovative solution must avoid inefficiently high storage costs and balance investment in storage, renewables, and other capacities.  
Classical energy production sources ensure the adjustment of the energy system through their temporal adaptability since they can provide energy when requested and can reduce or increase relatively flexibly the amount of energy supplied, depending on the installed power and the specifics of the production process. Instead, the removable battery system adjusts the energy system by taking over the amount of electricity that cannot be used and consumed at the time of production and storing it. Thus, consumers can use it or return it to the energy system when additional energy is demanded. As a result of the fact that most energy markets worldwide require a minimum capacity to participate, it is necessary to have a large number of electric vehicles using removable batteries that can ensure the adjustment of the entire energy system. Answering the research question, we analyze the viability of the solution of taking over the surplus of energy produced by renewable sources (at times when the classical grid cannot take over this surplus) within an integrated energy system that would use the removable batteries of electric vehicles for storage and adjustments. The conclusion we have reached is that the storage of electricity in removable batteries on electric vehicles will allow electricity transport without being burdened by temporal or spatial boundaries. Our paper has made a modest contribution to analytical research on the impact of the paradigm shift in road transport (from fossil fuel-based to electricity-based propulsion) on more efficient management of variable renewable energy, characterized by uncertainty. Among the limitations of our research worth mentioning is the focus is only on storing energy from unsolicited renewable sources on the market at the production moment. Another limitation is that the study considers static data on the average consumption of an electric car, the average number of km traveled by a vehicle (without making predictions on technological advances). Potential future research directions may expand the study to several variables, considering technical progress and other methods of efficient management of renewable energy sources, which can reduce the excess energy produced by renewable sources when the classical grid cannot take over this surplus.
