Clean and renewable energy sources are the preferable power system generations for the overall world. This research aims to present a very highly integrated, economic, professional, and simple construction, clean and natural resources usage of the renewable hybrid generation system. This research performs analysis, systematic representation, evaluation, and design of the hybrid proposed system—pico-hydraulic from home usage water and photovoltaic (PV)—to generate an optimal renewable generation system using a new professional control system. Applying this proposed technique in Egypt shows that the hybrid system successfully overcame Egypt’s energy crisis. Renewable energy will rise to 8.782% by increasing 7.323% (14,408.83 GWh/Y). Besides, this system increases the power supply reliability; it gives an additional emergency supply and reduces the exhausts from other generation stations (e.g., CO2). The saving from this hybrid system is very effective for; the residential sector (subscribes), which will be ranged from 9599.298 million E£/10Ys up to 86,393.68 million E£/10Ys that equals 5399.6 million $, government to use this extra generation energy to reduce the maximum loads from various stations. A practical model has been presented with results to verify the high efficiency of the proposed system that illustrates the effective performance of the used hybrid system.

Most power system planners are interested in the savings of electrical power consumption. Various references demonstrate that the highest consumed power is by the lighting systems standing around 19% of worldwide energy consumption. This article presents novel design methodology leading to maximizing revenue due to savings in electrical energy consumption through energy efficient installations. This hybrid methodology is built by combining benefits of the two traditional lighting design methods (lumen and specific connected load methods). This results in developing a new mathematical and applicable model with many advantages such as: high accuracy, fast calculations and most economical design. This proposed methodology is supported by MATLAB ® package to shorten the long time consumed by conventional procedures and simplify the complex manual calculations. The hybrid method verifies its effectiveness and efficiency for achieving the maximum savings in energies and costs through the detailed discussion of case studies. A comparison with traditional designs will be introduced to ensure the achieved savings in costs leading to high quality and efficiency of power systems. By practically applying this new hybrid technique particularly for the Egyptian residential and commercial sectors, the system is expected to achieve a huge savings in consumed lighting energies and costs, which can reach 4489.433415 million E£ "≈ 280.5895 million $ "USD"" each year. The presented case studies give accurate and promising results for the proposed methodology as a new trend in energy and money saving system, which is verified by implementing two case studies and comparing with results from DIALux program. The results of the proposed methodology are very effective compared with that of conventional methods for marked benchmarking features and validation. MATLAB ® simulation results of the proposed technique are implemented to verify its feasibility for any activity.

“…Road lighting has a considerable influence on traffic safety and the quality of the human environment [1][2][3] and is thus an indispensable component of pathways [4,5], sidewalks, and road equipment [6][7][8]. On roads, high visibility and facial recognition are imperative components of the interactions between users [9,10], and several studies of road lighting have accordingly demonstrated the benefits of public lighting installations on road safety, crime prevention, and traffic flow [1][2][3]11]. Currently employed street lighting technology is built upon years of experience and research [6-8, 12, 13].…”

“…e luminaire mounting height, street light spacing, luminaire inclination angle, and road surface properties are essential for ensuring the desired street lighting performance, measured in terms of the average road surface brightness, brightness uniformity, longitudinal brightness uniformity, and threshold increment (glare factor) [1][2][3]20]. Furthermore, though the use of lightemitting diode (LED) technology requires less energy consumption and can provide longer-lasting lighting than conventionally used discharge lamps [21][22][23][24], there remain several disadvantages to the use of LED lights, such as their higher cost, unpredictable lifetime, and excess blue/white glare for human eyes [25][26][27].…”

To enhance driving safety at night, a new freeform-surface street light luminaire was proposed and evaluated in this study that meets the requirements of the International Commission on Illumination (CIE) M3 class standard for road lighting. The luminaire was designed using simulations to optimize the location of the bulb according to the requirements of the standard. The light source IES file was experimentally obtained for the optimized luminaire prototype with a 150 W ceramic metal halide lamp using an imaging goniophotometer. The trial road lighting simulation results computed by the lighting software DIALux indicated that the proposed luminaire provided an average road surface brightness of 1.1 cd/m2 (compared to a minimum requirement of 1.0 cd/m2), a brightness uniformity of 0.41 (compared to a minimum requirement of 0.4), a longitudinal brightness uniformity of 0.64 (compared to a minimum requirement of 0.6), and a glare factor of 7.6% (compared to a maximum limit of 15%). The findings of the image goniophotometer tests were then confirmed by the results of a certified mirror goniophotometer test conducted by the Taiwan Accreditation Foundation (TAF). The results of this study can be used to provide improved street lighting designs to meet enhanced international standards.
