Renewable energy resources are currently being developed by Indonesia. The government is also targeting an energy mix of 23% to achieve renewable energy by 2025. One of the renewable energies is Solar Photovoltaic Generation System. On the other hand, an industrial area is an area filled with factories that are large enough so that it has great potential to develop Rooftop Solar Photovoltaic with the advantage of reducing land investment costs without reducing the operational function of the factory. The purpose of this research is to simulate the technical and economic performance of a 200kWP Solar Photovoltaic On grid on the rooftop of a factory building using Helioscope software in an industrial area in West Java. The simulation result shows that the average values for Global Horizontal Irradiance (GHI), Electrical Energy Production, and Performance Ratio (PR) in one year are 138.2 kWh/m2, 21,977 kWh, and 78.06%. Meanwhile, the total Electrical Energy Production in one year is 263,723.6 kWh. The total investment value of the 200kWP Rooftop Solar Photovoltaic On grid on the factory building is 2,457,850,800 IDR. Based on the economic feasibility study, it can be concluded that the 200kWP Rooftop Solar Photovoltaic On grid on the factory building rooftop is economically feasible as long as the interest rates is less than 12.71% (Internal Rate of Return / IRR).

Electrical Energy Production

In order to research the process of development of the energy systems of Ukraine, the current status and problems of development of nuclear, thermal and renewable energy are analyzed. The global trends in the development of nuclear energy is identified and it is noted that after the short-term decline caused by the accident at the «Fukushima-1» nuclear power plant, a gradual increase in the number of operating reactors has begun. The crisis situation in the nuclear and thermal energy market is outlined. Within the framework of the existing PSO (Public Service Obligation) model, the National nuclear power generating company «Energoatom» suffers significant losses. The limitation of electrical energy production at nuclear power plants in 2020 is an insufficiently grounded measure that will adversely affect the energy security of the country. Shutting down the power units of nuclear plants means that instead of producing energy one begins to consume energy, while a constant duty with ongoing servicing of equipment and maintaining the security systems is required. It is indicated that the coal-fired power plants of Ukraine have already developed their estimated resource and have an extremely low usage rate of installed capacity. In addition, coal-fired power plants in Ukraine are used in maneuvering modes, to cover peak loads, which leads to accelerated wear and tear of equipment and reduces production efficiency. A comparative analysis of the development of renewable energy sources (RES) is carried out and it is proved that the increase in electrical energy production due to RES requires the development of sufficient maneuvering capacities. The current situation indicates that the capacities of HPP and PHES are not sufficient, so at this time coal-fired power plants are used for such purposes, but such a part-time mode of operation leads to further wear and tear of equipment and an increase in emergency situations.

Electrical Energy Production

In recent years, decreasing reserves and environmental problems related with fossil fuels have increased the demand for clean and renewable energy sources, as with all over the world and also in Turkey. Wind energy is the one of the most rapidly growing among the renewable energy sources in terms of technological and utilization. Turkey is one of the rich countries in Europe in respect to wind energy potential. Productive and effective use of this potential is very important for Turkey that is depended on foreign countries especially in respect to fossil energy sources. Wind speed values are the most important data in calculation of electrical energy from wind turbines. In this study, latest developments and energy-power equations related to wind turbines are investigated. Using of the data obtained from the wind measurement station installed in Sakarya-Esentepe region, annual electrical energy production of an example wind plant is predicted.

Sustainability has been greatly impacted by the reality of budgets and available resources as a targeted range of carbon emission reduction greatly increases due to climate change. This study analyses the technical and economic feasibility for three types of solar photovoltaic (PV) renewable energy (RE) systems; (i) solar stand-alone, a non-grid-connected building rooftop-mounted structure, (ii) solar rooftop, a grid-connected building rooftop-mounted structure, (iii) solar farm, a grid-connected land-mounted structure in three tropical climate regions. Technical scientific and economic tools, including life cycle assessment (LCA) and life cycle cost assessment (LCCA) with an integrated framework from a Malaysian case study were applied to similar climatic regions, Thailand, and Indonesia. The short-term, future scaled-up scenario was defined using a proxy technology and estimated data. Environmental locations for this scenario were identified, the environmental impacts were compared, and the techno-economic output were analysed. The scope of this study is cradle-to-grave. Levelised cost of energy (LCOE) was greatly affected due to PV performance degradation rate, especially the critical shading issues for large-scale installations. Despite the land use impact, increased CO2 emissions accumulate over time with regard to energy mix of the country, which requires the need for long-term procurement of both carbon and investment return. With regards to profitably, grid-connected roof-mounted systems achieve the lowest LCOE as compared to other types of installation, ranging from 0.0491 USD/kWh to 0.0605 USD/kWh under a 6% discounted rate. A simple payback (SPB) time between 7–10 years on average depends on annual power generated by the system with estimated energy payback of 0.40–0.55 years for common polycrystalline photovoltaic technology. Thus, maintaining the whole system by ensuring a low degradation rate of 0.2% over a long period of time is essential to generate benefits for both investors and the environment. Emerging technologies are progressing at an exponential rate in order to fill the gap of establishing renewable energy as an attractive business plan. Life cycle assessment is considered an excellent tool to assess the environmental impact of renewable energy.

Wind turbine installation worldwide has increased at unrested pace, as it represents a 100% clean energy with zero CO2 and pollutant emissions. However, visual and acoustic impact of wind turbines is still a drawback, in particular in urban areas. This paper focuses on the performance evaluation of an innovative horizontal axis ducted wind turbine, installed in the harbour of Genova (Italy) in 2018: the turbine was designed in order to minimize visual and acoustic impacts and maximize electrical energy production, also during low wind speed periods. The preliminary study and experimental analyses, performed by the authors in a previous study, showed promising results in terms of energy production, compared to a traditional generator ( factor >2.5 on power output). In the present paper, the test campaign on a scaled-up prototype, installed in the urban area of Genova, is performed, with a twofold objective: (i) comparison of the ducted innovative turbine with a standard one, in order to verify the increase in energy production; (ii) analysis of the innovative turbine for different wind speeds and directions, evaluating the influence of ambient conditions on performance. Finally, based on the obtained results, an improved setup is proposed for the ducted wind turbine, in order to further increase energy production mitigating its visual impact.

Two thermodynamic power cycles are analytically examined for future engineering feasibility. These power cycles use a hydrogen-oxygen fuel cell for electrical energy production and use the thermal dissociation of water for regeneration of the hydrogen and oxygen. The first cycle uses a thermal energy input at over 2000K to thermally dissociate the water. The second cycle dissociates the water using an electrolyzer operating at high temperature (1300K) which receives both thermal and electrical energy as inputs. The results show that while the processes and devices of the 2000K thermal system exceed current technology limits, the high temperature electrolyzer system appears to be a state-of-the-art technology development, with the requirements for very high electrolyzer and fuel cell efficiencies seen as determining the feasibility of this system.
