“…For an ideal transformation of the power absorbed by a source that emits monochromatic light with a wavelength of 555.5 nm results a luminous efficacy η= 683 lm/W. In reality, the current artificial light sources have a much lower luminous efficiency [7][8][9][10]. In the table below are some examples.…”

Energy efficiency is one of the priority European Union under the Europe 2020 Strategy. A key area in energy efficiency to be acted upon is street lighting. Public lighting consumption in Romania represents about 1% of total electricity consumption. The choice between the redesign of public lighting systems or use solutions of retrofit for the replacement of lamps or luminaires can be made following a flowchart analysis but also taking into account the investments budget.

“…The main advantages of PD technologies include high energy efficiency (up to 30%) and modularity (5-50 kW), in addition to being particularly suited to distributed generation systems [39,[49][50][51][52]. Based on the literature [54][55][56][57][58][59][60][61][62], the specific features of CSP technologies are presented in a comparative manner in Table 1. PT systems occupy a large area, having low thermodynamic efficiency due to their low operating temperature.…”

“…ST has high thermodynamic efficiency due to a high operating temperature; it occupies a large area, it has high installation cost and records high heat losses. Finally, PD occupies small area, features high thermodynamic efficiency due to high operating temperature, but it requires a high installation cost [54][55][56][57][58][59][60][61][62].…”

Nowadays, the evolution of solar energy use has turned into a profound issue because of the implications of many points of view, such as technical, social, economic and environmental that impose major constraints for policy-makers in optimizing solar energy alternatives. The topographical constraints regarding the availability of inexhaustible solar energy is driving field development and highlights the need for increasingly more complex solar power systems. The solar energy is an inexhaustible source of CO2 emission-free energy at a global level. Solar thermal technologies may produce electric power when they are associated with thermal energy storage, and this may be used as a disposable source of limitless energy. Furthermore, it can also be used in industrial processes. Using these high-tech systems in a large area of practice emboldens progress at the performance level. This work compiles the latest literature in order to provide a timely review of the evolution and worldwide implementation of Concentrated Solar Power—CSP—mechanization. The objective of this analysis is to provide thematic documentation as a basis for approaching the concept of a polygeneration solar system and the implementation possibilities. It also aims to highlight the role of the CSP in the current and future world energy system.

“…A number of pilot projects are currently underway in this field, so these systems will be validated and then implemented on a large scale, including energy storage solutions, so these costs are expected to decline in the near future. In addition, the government supports clean energy through a generous system of subsidies, with a number of rules being implemented at the national level that encourages the installation of small green energy production capacities [46] with renewable energy producers receiving these subsidies through the mandatory green certificates quota system.…”

Since mid 2010, petrol consumption in the transport sector has increased at a higher rate than in other sectors. The transport sector generates 35% of the total CO2 emissions. In this context, strategies have been adopted to use clean energy, with electromobility being the main directive. This paper examines the possibility of charging electric vehicle batteries with clean energy using solar autochthonous renewable resources. An isolated system was designed, dimensioned, and simulated in operation for a charging station for electric vehicles with photovoltaic panels and batteries as their main components. The optimal configuration of the photovoltaic system was complete with improved Hybrid Optimization by Genetic Algorithms (iHOGA) software version 2.4 and we simulated its operation. The solar energy system has to be designed to ensure that the charging station always has enough electricity to supply several electric vehicles throughout all 24 h of the day. The main results were related to the energy, environmental, and economic performance achieved by the system during one year of operation.
