Concentrated Solar Power

The Chilean Energy Policy calls for 15 percent of new power generation capacity to come from renewable energy sources from 2006 to 2010, and then a 5% of electric energy generated from renewable energy sources with gradual increases in order to reach 10% by 2024. Neither the government nor the power generation sector plans mention solar energy to be part of the renewable energy initiative. Part of this apparent lack of interest in solar energy might be due to the absence of a valid solar energy database, adequate for energy system planning activities. Monthly means of solar radiation are used in order to estimate the solar fraction for a 100 MW plant for four given locations. Our analysis considers two cases: operation during sunlight hours, and continuous operation during 24 hours a day. A net energy analysis for concentrated solar power (CSP) plants in Chile is then performed, considering the energy costs of manufacturing, transport, installation, operation and decommissioning. The results indicate that the CSP plants are a net energy source in three of the four locations, when operating in sunlight-only mode. This is due to the lower radiation levels available at that location, which implies a high fossil fuel back-up fraction. In the continuous operation mode, the CSP plants become fossil fuel plants with solar assistance, and therefore all locations display negative net energy. Based on this result, the back-up fraction required for the plants to be net energy sources is estimated from the EROEI as function of the back-up fraction. It is estimated that the net energy analysis is a useful tool for determining under which conditions a CSP plant becomes a net energy source, and thus can be utilized in order to define geographical locations and operation conditions where they can be considered renewable energy sources.

At present the power plant has a high dependence on energy sources such as diesel, natural gas and coal, while its energy source in nature is increasingly scarce, this situation encourages the development of renewable energy, one of which is in micro hydro power plants. This study aims to determine the effect of the width of the work triangle on the highest rpm produced. the fall of water on the pinwheel is set from the position angle of the nozzle 00, 150, 300, 450, 600, 750 and from the angle of the nozzle 00, 50, 100, 150, 200, 250, 300, 350 and 400 on the semicircular blade turbine, triangle blade turbine , and fin blade turbines. Semicircular turbine blade, working triangle area produces greater rpm at position of angle nozzle 00 and angle of nozzle 250 with area of work triangle 360,36 cm2, where the position produces 216 rpm at windmill rotation and 1626 rpm at generator rotation. When the nozzle position angle 150 and the nozzle angle 200 with the working triangle area 264.27 cm2, produce 221 rpm at the pinwheel rotation and 1711 rpm at the generator rotation. while at the nozzle position angle of 300 and the angle of the nozzle 100 the area of the triangle works 134.37 cm2 and produces 173 rpm at the spinning wheel and 1307 rpm at the generator rotation. on the triangle blade turbine and fin blade, the working triangle area does not affect the rpm produced.

The Chilean Energy Policy calls for 15 percent of new power generation capacity to come from renewable energy sources from 2006 to 2010, and then a 5% of electric energy generated from renewable energy sources with gradual increases in order to reach 10% by 2024. Concentrated solar power is an interesting alternative to help achieving those objectives, as it is estimated that northern Chile has high radiation levels, coupled with high values of the local clearness index and availability of flat terrain. The present report investigates the net energy attributes of parabolic trough plants installed in the Atacama Desert. Monthly means of solar radiation are used in order to estimate the solar fraction for a 100 MW plant at three different locations. Our analysis considers three cases: operation during sunlight hours only, with and without fossil fuel back-up, and continuous operation during 24 hours a day. The net energy analysis for concentrated solar power (CSP) plants is then performed, considering the energy costs of manufacturing, transport, installation, operation and decommissioning. The results indicate that the CSP plants are a net energy source when operating in sunlight-only mode and that the energy payback time is a linear function of the total operation time when utilizing fossil fuel back-up. In the continuous operation mode, the CSP plants become fossil fuel plants with solar assistance, and therefore all locations display negative net energy. Based on this result, the back-up fraction required for the plants to be net energy sources is estimated from the EROEI as function of the back-up fraction. It is estimated that the net energy analysis is a useful tool for determining under which conditions a CSP plant becomes a net energy source, and thus can be utilized in order to define geographical locations and operation conditions where they can be considered renewable energy sources.

AbstractRenewable energy sources have been placed as the key to facilitating to provide source of electricity generation. Solar power is one of the most preferable one among renewable energy sources due to the easy to generate in suitable environment. However, there are concerns with the location of solar power plants installation which causes low efficiency and ineffective use. Hence, determining the location for the usage of solar power sources is critical to mitigating those concerns. In addition, Turkey has been focused on investments on sustainable renewable energy sources and there are few studies which work on cities to reveal potential sources. In this study, GIS and intuitionistic fuzzy set based multi-criteria decision-making method is proposed for determining the most suitable areas for solar energy power plant potential site selection in Erzurum province, Turkey. Firstly, a solar energy power plant potential site selection map is made using a GIS program along with considering ecological risks and ecological criteria. Secondly, 20 districts of Erzurum are investigated in terms of 10 criteria (slope, aspect, solar irradiation, land use, wind speed, air temperature, air pressure, air humidity, land surface temperature and transmission line) using intuitionistic fuzzy sets. In these parameters the first time we looked the land use surface. The land use surface is affected the efficiency of the solar power plant. Finally, the comparisons of two methods are done to check consistency of results obtained. The results indicate that both approaches achieve same areas as the most suitable locations for solar power plants installations for Erzurum province in Turkey. The aim of this work is first to investigate possible locations for solar power plant installation using a mapping method, GIS, and then, Intuitionistic Fuzzy is applied to the problem to obtain optimum areas for solar energy. Also, more accurate results are provided comparing results of two methods, GIS and Intuitionistic Fuzzy. The results expose that 25,065.3 km2 for solar power plant suitable for solar power plan installation.

It is estimated that at least 600 million people in Africa lack access to electricity and three out of five people don’t have access to electricity in Sub-Saharan Africa. Though Africa is rich in a wide range of energy resources including solar, bio, natural gas, oil, coal and Uranium, the continent is far from energy self-sufficiency. Addressing climate change will require deep and quick reductions in fossil fuel use so that the systems developed around producing, transporting, and consuming energy are decarbonized by the middle of the century. In the ongoing age, sustainable power source has taken another swing to limelight on the planet, particularly in developed and emerging nations, as it assumes a noteworthy part both in economy and the general job of the world. Significantly, Nigeria an oil-rich country, comes as no surprise that almost all of her energy consumption comes from non-renewable energy sources as coal, natural gas and oil, and as such it is highly vulnerable to shocks due to overdependence on the fossil sources; often time is controlled by the international market. On the whole, the fossil fuel is expected to span only but a millennium (1700-2700) of human civilization while the imperative of an energy shortage situation is felt in every sector of the country considering the poor electricity consumptions in the country, which has reflected on the country’s economy and productivity rate. In revamping the economic sectors in Nigeria, the need for an alternative energy sources that is augmentable in supply keeping in view sustainable development as the hallmark for all sector development. Thus far, Nigeria ought to likewise be opened to universal investments as this would help support the improvement of its assets. This paper, therefore, supports no other sources but renewable energy in promoting the countries productivity at all segments. It further stressed on the implementation of the country’s Renewable Energy Master Plan (REMP) to meet global competitors by the year 2030. Similarly, senior political figures, policymakers and CEOs should engage in a policy dialogue by identifying unique opportunities and best practices for developing and investing in Nigeria and in Africa’s energy markets for “…without this energy supply, the sophisticated skills of the industrial world are merely a burden in the struggle for survival.”

AbstrakEnergi surya (matahari) merupakan salah satu sumber energi terbarukan yang paling penting dan sangat berlimpah di Indonesia. Dengan potensinya yang sangat besar tersebut, energi surya diyakini menjadi sumber energi utama di masa depan. Eenergi surya di Indonesia sangatlah besar. Indonesia memiliki sekitar 4.8 KWh/m2 atau setara dengan 112.000 GWp energi surya. Sayangnya energi surya ini belum mendapatkan porsi yang semestinya di negara ini. Dari total potensi energi surya tersebut, Indonesia baru memanfaatkan sekitar 10 MWp. Hambatan yang masih sering terjadi pada penggunaan PLTS ini adalah pada tidak dapatnya diprediksi keacaan cuaca dalam waktu yang singkat, sehingga produksi energi listrik sulit dapat memenuhi target yang diharapkan, dan hal ini membuat ketidak nyamanan pengguna. Perlunya penelitian terhadap efisiensi modul solar panel, karena saat ini efisiensi yang dihasilkan modul solar panel masih sangat rendah, sehingga untuk mendapatkan 1 KWh energi listrik masih tergolong sangat mahal.Abstract Solar energy (sunlight) is one of the renewable energy sources the most important and very abundant in Indonesia. With such huge potential, solar energy is believed to be the main energy source in the future. Solar Eenergi in Indonesia is very large. Indonesia has around 4.8 KWh / m2 or equivalent to 112,000 GWp of solar energy. Unfortunately, solar energy has not received the proper portion of the country. Of the total solar energy potential, Indonesia has only utilized approximately 10 MWp. Barriers are still common in the use of solar power is at the inability to predict the weather keacaan in a short time, so the production of electrical energy is difficult to meet the expected targets, and this makes it an inconvenience for the user. The need for research on the efficiency of solar panel modules, because the current efficiency of the resulting solar panel module is still very low, so to get 1 kWh of electrical energy is still relatively very expensive.
