Water pumping for irrigation has a relatively high energy demand, depending on the applied irrigation method. At the same time, there is a considerable energy from the sun during the irrigation period. The solar PV (photovoltaic) technology may be suitable to ensure electric energy for pumping in many cases in agriculture, where the electric network is not available or reduction of the energy costs is wanted. There are some pilot plants for water pumping on the base of solar energy in the world and the spreading of these solar technologies is predictable. The solar energy based pumping process can be approached both in theoretical and experimental ways. In this paper, both the theoretical questions of the solar based pumping process and the experimental results of a model testing pump station powered by PV panels are shown.

Energy is considered as a key source for the future and plays a pivotal role in its socioeconomic development by raising the standard of living and the quality of life, not only for India but also for the world. In view of the scarce fossil fuel reserves, solar energy is one of the important sources of renewable energy used in India because of the suitable climate conditions. It receives about 5485.17 Wh/m2day of solar insolation with an annual total of about 19, 74, 661.2 Wh/m2. Except for the monsoon months, solar radiation incidence is very encouraging, from the application point of view. For the efficient functioning and better performance of solar energy device, the information of solar radiation and its components at particular location is very essential for designing the solar energy devices. Therefore, over the years, several empirical correlations have been developed in order to estimate the more appropriate solar radiation in India as well as around the world. Here we present a review of different solar radiation models which predict global solar radiation and discussed the long-term plan to meet future energy demand with renewable energy due to economy growth.

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.

Environmental Causes

The WHO report shows that air in the majority of cities in the world is polluted to a large extent. Air pollution is one of the basic environmental causes of premature deaths in the world. The main source of air pollution in cities is the low emission associated with fuel combustion to generate heat for buildings heating, communication and industry. The existing buildings in Poland are characterized by high energy and, consequently, ecological potential. The aim is to estimate predicted energetic and ecological effects of activities that adapt existing residential buildings to the requirements for the thermal protection of buildings in Poland and presenting the possibility of using renewable energy sources. The energy demand for heating buildings at 60-70 kWh/(m2rok) has been adopted. The calculations show that as a result of this adjustment, the energy demand for heating in residential buildings may decrease by an average of around 67% compared to 2011. Such actions will reduce the overall emissions of air pollution from households by reducing the energy requirement for heating apartments from about 30% to about 67%, depending on the type of pollutant.

Population Urbanization

Solar Photovoltaic (SPV) is a novel technology to harvest solar energy as and when we talk about replacing the conventional grid electricity. The degree of development of a country is measured by the amount of energy used by humans. Energy demand is increasing due to population, urbanization and industrialization. As a result conventional electricity needs to be replaced with non conventional energy resources so as to save the environment from pollution due to increased number of unwanted gases and dust particles in the air. Harmful gases like COx and SO2 in the environment are affecting the Air Quality Index (AQI) and making it difficult for humans to breathe. Solar Energy is a clean and green solution to improve the AQI of the earth. In this research we study and analyze the performance of a grid interactive SPV plant installed at Academic Block-II, Integral University. In this regard, we measure the performance ratio for 4 (four) months. The effect of shading on the PV panel is reviewed due to deposition of dust particles and bird feces.

Increasing Demand

In the 21st century, energy supply has been one of the challenging issues that the world is facing. This is due to growing populations which results in more homes, businesses, and industries and has resulted in a large number of new appliances that increased the energy demand to a new level. The electric system we are using today is a one-way energy flow. Smart grid has emerged as the solution of continuously increasing demand. It is the future of electric energy system and also the power grid for upcoming generations. SG system works on the dual technique, that is, it counts electricity flow and the information which could deliver and distribute the energy universally by automating the existing electrical network.

This paper deals mainly with the development of utilization of endogenous fluids in the world and particularly in Italy, together with a forecast of the potential increase in geothermal production. At the end of 1972 the installed capacity of the world’s geothermoelectric plants was approxim ately 1000 M W , of which 390.6 M W are installed in Italy. In the same year the electric energy generated by Italian power stations was 2582.4 GW h. In some countries, geothermoelectric energy costs ranged from 1.4 to 2.5 U.S. mills/M J (5 to 9 mills/kW h) as com pared with 1.66-3.9 U.S. mills/M J (6-14 mills/ kW h) for alternative sources. T he total geothermal capacity in the world is expected to double and perhaps to triple in the 1980s, as new installations are being constructed or planned in several therm al areas. The utilization of geothermal fluids for evaporating low-boiling liquids (freon, isobutane, etc.) or for driving a gravim etric loop, offers attractive possibilities of using therm al waters also for the generation of electricity. In many countries, low enthalpy fluids are used directly for other purposes (domestic and greenhouse heating, refrigeration and air-conditioning, production of fresh water, drying seaweeds and diatomites, etc.). The cost of geothermal heat thus employed is 0.7-1.2 $/GJ as com pared with about 2.6 $/GJ if fossil fuels are used. Due to this attractive cost, in the next few years there should be a rem arkable development in this type of utilization of low enthalpy fluids.

Passive Cooling System

High energy demand is leading to the replacement of fossil energy with renewable sources such as solar energy. Solar cells are devices used to generate solar energy. However, when exposed to sunlight with high intensity, a solar cell can suffer a decrease in performance due to overheating. This issue can be addressing by adding a cooling system. This study used a passive cooling system by adding a heat sink with fins to the body panel of the solar cell. The advantage of the passive cooling system is that it does not require additional energy. The number of fins and types of material were varied to obtain the best passive cooling system. The number of fins used was 5, 10, and 15, and the materials used were aluminum and copper. The wind speed vector and the temperature distribution were investigated through simulation. The results showed an increase in the number of fins provided better cooling capacity and increased the photovoltaic performance. The best cooling capability and performance were obtained using 15 fins with a copper base and fin heat sink materials. The decrease in temperature and the increase in efficiency were 10.2 °C and 2.74%, respectively. Therefore, the use of passive cooling system based on heat sinks with fins could provide a potential solution to increase performance and prevent overheating of photovoltaic (PV) panel systems.

Recently, the technology of floating photovoltaic panels has demonstrated several advantages over land installations, including faster deployment, less maintenance cost, and higher efficiency. Lake Nasser is the second largest man-made freshwater lake in the world with a surface area of almost 5000 square km. Being in one of the hottest areas in the world, evaporation of water causes loss of very precious and scarce resources: freshwater. Fortunately, the lake is also located in a very rich area in solar energy. This paper presents a study to utilize Lake Nasser’s surface for massive production of solar energy, while significantly reducing the loss of water by evaporation from the lake surface. The project has the potential to be one of the largest producers of low-cost clean electric energy in the world for Europe and the Middle East and North Africa (MENA) region, especially with the ongoing efforts to connect the North African countries with the European super power grid. The study shows that the first phase of the project is expected to deliver about 16% of European need of electricity and save about 3 billion m3 of freshwater. The subsequent phases will provide low-cost green energy to replace the combustible fuels in Europe by 2045, while saving up to 10-12 billion m3 of freshwater lost by evaporation from Lake Nasser.
