Photovoltaics (PV-also called solar photovoltaic devices) are used to harness the power of the sun via the electronic process that occurs within semiconductor cells. The solar energy is absorbed by the cells, which causes the electrons to break away from their atoms, allowing them to flow within the material to produce electricity. This electricity will become the renewable energy for Kentucky, as the generation of coal will but come to a stop within the near future. Like Denmark who is running on 100% renewable generation we must stride to become fully operational on solar. In the present work, we systematically studied about renewable energy resources, in particular, solar energy for the application of photovoltaic panels in Eastern Kentucky. By analyzing data from our PV cells at Morehead State University designed to follow the direction of the sun for optimized output and by incorporating MPPT charge controllers, we have constructed a maximum power algorithm that performs best for the location. Utilizing these, measurements of daily electricity production in comparison to the average power needed for household use has validated our research. With the advancements in solar cell technology what was once impossible is now reality, as solar power can easily power this region based on our data. Knowing this, being a prime location we can now push to enable the advancement of renewable energy production and become less dependent on fossil fuels, thus creating an infrastructure that will run off solar power.

Abstract. Increasing the production of clean and environmentally friendly energy has become one of the world agendas as a strategic effort in dealing with long-term climate change. Seeing the potential of the energy produced, the ease in the installation process, with the small risk of harm generated, solar energy has received significant attention from many countries in the world. The potential for solar energy in Indonesia alone reaches 207 GWp, but only 145.81 MWp has been utilized. Currently, the Indonesian government has set a target to build a Solar Power Plant capacity in 2025 of 6.5 GWh. Urban areas are areas with higher energy demand than rural areas, but the availability of vacant land in urban areas is very minimal for installing solar power plants. Therefore, rooftop solar PV(Photovoltaic) can be a solution in dense areas such as cities. Good planning by looking at the potential resources and energy needs in spatial is needed to manage and utilize energy optimally and sustainably in urban areas. This study aims to develop a geospatial assessment for plan smart energy city that uses rooftop solar PV's potential energy in every building that is effective and efficient. The novelty in the analysis of the distribution of the potential for rooftop solar PV development in urban areas integrates meteorological and spatial aspects and socio-economic aspects. Integration of multi-dynamic spatial data uses in determining the rooftop solar PV construction location, such as meteorological data for solar energy potential, increasing energy needs of each building, and socio-economy data. The data source used comes from statistical data and remote sensing data. The analysis will be carried out temporally (2008, 2013, and 2018) to see the pattern of changes in aspects used in a certain period so that the development plan can be carried out more optimally. This research's output is the formation of a priority analysis of solar PV rooftop construction in urban areas, especially the city of Bandung. The result of energy can also produce by the construction of rooftop solar PV in a potential area. This research is expected to be utilized by policymakers to develop renewable energy in the city of Bandung and increase community participation in switching to renewable energy.

Hydrogen Storage System

Many significant features lead to consider hydrogen as an interesting energy carrier. Hydrogen can be burned with pure oxygen thus the production of CO2 and NOx is avoided. Since molecular hydrogen does not exist on the earth it has to be produced from fossil fuels or from renewable energy sources. Energy from fossil fuels can be transferred into hydrogen and released elsewhere. So relevant reduction of emission of pollutant can be achieved in critical zones at the centres of large cities. Nevertheless the losses occurring during production, distribution and storage of hydrogen lead to an increased consumption of the primary energy source (fossil fuels) and to increased emission levels (CO2 and others). Hydrogen can be obtained from renewable sources such as the solar energy and used in situ for power generation. In this case hydrogen can act as an energy carrier which allows a local energy storage. In such a way the time dependent availability of the solar energy and the production level of the power plant can be decoupled. In a distributed generation context a small size solar power plant equipped with a hydrogen storage system has been studied. Different storage options have been investigated and compared. Finally a liquid hydrogen storage system is proposed. The peculiarities of the selected system allow a reduction of losses, size of machinery and energy requirements. The paper presents an analysis of the more relevant issues related to the different hydrogen storage options suitable for the present application. After the characterization of the solar field in terms of energy availability and the specifications of both the hydrogen production system and the power generation unit, the design of a liquid hydrogen storage system is presented and widely discussed. This method is particularly useful in the plants management (for example nuclear or coal plants), where it’s impossible or very difficult to modify power level, as well. So, such a static system would be useful in order to allow power modulation by H2 plant. In order to do this, a research for individuating high volumic (and mass) specific capacity systems should be driven.

Development Plans

According to the Fifth Five Year Development Plan, in Iran, renewable resources, under the green horizon scenarios, must provide 5,000 MW of electricity. Among different types of renewable source of energy, there is no shortage of information in Iran, which is located near to zero line (earth’s equator), with about 300 clear sunny days in a year, about setting policies promoting solar energy. Taking into account the availability and benefits of solar energy for Iran, this paper has focused on solar energy.Recent statistics show that, if the current development plans proceed, the capacity of the installed renewable energy systems would reach 2.8GW by 2030. This requires more than 2800 million US dollar investment in 20 years, i.e., 2010 to 2030. Despite the advantages of using solar energy, such as reducing greenhouse gases, it is important to note that solar power is 2.5 to 5 times as expensive as electricity from existing conventional power sources, such as coal and other sources. In order to encourage people to use solar power, there is a need to change our laws and establish an integrated energy regulation, involving tax policy mechanisms to support the deployment of solar energy in Iran. As Iran is dependent upon its fossil fuels, the transition from fossil fuels to renewable, which is a worldwide goal to reduce GHG or CO2 emissions, requires the adoption of a comprehensive policy and integrated regulation nationwide, taking a multidisciplinary approach. This paper exemplifies and considers the 2005 Energy Policy Act and Investment Tax Credit (ICT) for residential energy property, illustrating how solar-energy-regulation could contribute to the sustained development of solar energy. The main purpose is to help the development of sustainable solar energy regulation in Iran.

Energy security and stability are currently the main issues throughout the world. Applied research is carried out all over the world in order to increase a share of renewable energy sources in the overall task of energy generation. In near future environmentally friendly energy sources should be found that will enable the mankind to cover its energy needs. Renewable energy sources are currently offered worldwide as an environmentally friendly and acceptable solution; however, one may always wonder whether it is realistic to expect such energy sources to be developed at a level sufficient to meet the mankind’s ever increasing energy needs. This caution is caused by the following facts associated with the renewable energy sources available today: the wind energy is not everywhere available in sufficient quantities, solar energy is not sufficiently used, hydropower (we refer to small hydro power plants), is not big enough for this quantity of energy, geothermal energy can be optimally used only at places where thermal energy from the inner core of the Earth is near the surface, tidal energy (energy of the waves) has great potentials but is very little used due to its scarcity and non-accessibility, bioenergy, as a substitute for conventional fossil fuels, is not completely environmentally friendly or acceptable due to the emission of greenhouse gases in the atmosphere. On the other hand, without implementing the adequate policies in the energy sector operation, it is not possible to have any industrial, economic or social progress in the world. Energy security and stability are only one part in achieving the ultimate goals: sustainable economy, clean environment, high standard of living, prosperity and health of the population. In the light of all the above, the paper will investigate the state and perspective of renewable energy sources with a special emphasis on the potential of solar energy.

<p>Can the 1.5 deg C warming target still be met with an aggressive phaseout of fossil fuels coupled with a 100% replacement by renewable energy?  We address this question in our modeling study by computing the continuous generation of global wind/solar energy power along with the cumulative carbon dioxide equivalent emissions in a complete phaseout of fossil fuels over a 20 year period. We assume a baseline of energy status at 2018, as well as the EROI of currently available wind/solar energy technologies.  We compare these computed emissions with the state-of-the-science estimates for the remaining carbon budget of carbon dioxide emissions consistent with the 1.5 deg C warming target. Our conclusion is that it is still possible to meet this warming target if the creation of a global 100% renewable energy transition of sufficient capacity begins very soon, coupled with aggressive negative carbon emissions. The latter technology uses a fraction of total renewable energy delivery for direct air capture for permanent crustal storage over the last ten years of this energy transition that is compatible for simulations with no more than 10 to 15 % reinvestment of renewable energy to make more of itself. More efficient renewable technologies in the near future will make this transition easier.  The maximum amount of fossil fuel consumed in our scenarios for the complete transition is no more than 5% of the proven reserves of coal, natural gas and oil as currently estimated.  </p><p> </p><p> </p>

Renewable energy is being promoted amidst rising environmental concerns associated with fossil-fuel usage for power generation. The stock of such fuels is also limited and is fast depleting. Renewable energy sources such as solar photovoltaic (PV) systems present a clean alternative that has become cost-competitive with conventional thermal power generation systems. However, to counter the intermittent nature of solar power and ensure firm power supply, energy storage is essential. This paper presents a comparative analysis of power supply options based on two solar energy technologies - PV and concentrated solar power (CSP). Energy storage in the form of battery and thermal energy respectively has been included and different combinations of supply options, along with utility grid, have been analyzed in terms of the levelized cost of electricity (LCOE). The LCOE values for supplying a particular substation load in India have been compared and it was found that CSP with thermal energy storage emerged to be the economically viable option for supplying the load.

Renewable energy interest is increasing day by day due to the progressive decline of fossil fuels and negative effects on the environment. As is known, generating energy using solar energy is the most popular of renewable energy source applications. One of the reasons for this is that the sun, which is the source of all the energy in the world, will give energy for a very long time. Another important reason is the rapid developments in semiconductor electronics technology. Direct solar water heating with solar collector, power generation without photovoltaic panels, and even power generation with concentrated parabolic systems. In this research, electricity is generated by solar panels used in a traditional plateau house, photovoltaic solar batteries from solar energy and electricity stored in battery benches and electricity stored in the battery is converted to mains electricity through an inverter if necessary. Saving electric elements at home are selected, and the minimum power required for basic needs is provided. In addition, the economics of the designed system was investigated and efficiency analysis was carried out considering the energy efficiency at the optimum level.

This study presents an outlook on the renewable energies in Iraq, and the potential for deploying concentrated solar power technologies to support power generation in Iraq. Solar energy has not been sufficiently utilized at present in Iraq. However, this energy source can play an important role in energy production in Iraq, as the global solar radiation ranging from 2000 kWh/m2 to a 2500 kWh/m2 annual daily average. In addition, the study presents the limited current solar energy activities in Iraq. The attempts of the Iraqi government to utilize solar energy are also presented. Two approaches for utilizing concentrated solar power have been proposed, to support existing thermal power generation, with the possibility of being implemented as standalone plants or being integrated with thermal power plants. However, the cost analysis has shown that for 50 kW concentrated solar power in Iraq, the cost is around 0.23 US cent/kWh without integration with energy storage. Additionally, notable obstacles and barriers bounding the utilization of solar energy are also discussed. Finally, this study proposes initiatives that can be adopted by the Iraqi government to support the use of renewable energy resources in general, and solar energy in particular.
