Currently, 80% of conventional energy is used to fulfill general public's needs andindustries. The depletion of oil and gas reserves and rapid growth in conventional energyconsumption have continuously forced us to discover renewable energy sources, like solar, wind,biomass, and hydropower, to support economic development in the future. Solar energy travels at aspeed of 186,000 miles per second. Only a small part of the radiant energy that the sun emits intospace ever reaches the Earth, but that is more than enough to supply all our energy demand.Indonesia is a tropical country and located in the equator line, so it has an abundant potential ofsolar energy. Most of Indonesian area get enough intensity of solar radiation with the average dailyradiation around 4 kWh/m2. Basically, the solar systems use solar collectors and concentrators forcollecting, storing, and using solar radiation to be applied for the benefit of domestics, commercials,and industrials. Common applications for solar thermal energy used in industry are the SWHs, solardryers, space heating, cooling systems and water desalination.

In recent years, it is getting attention for renewable energy sources such as solar energy, fuel cells, batteries or ultra capacitors for distributed power generation systems.solar energy maintains life on earth and it is an infinite source of clean energy.Solar radiant energy accounts for most of the usable renewable energy on this earth. Photovoltaic (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductor that exhibit the photovoltaic effect. Since last five decades, numerous studies have been performed on different design aspects and performance characteristics of Photovoltaic (PV) cells with a common objective of producing fully integrated PV modules to compete with the traditional energy sources. There is an increasing trend for the use of solar cells in industry and domestic appliances because solar energy is expected to play substantial role in future smart grid as distributed renewable source. The proposed model is based on a behavioral cell model for modeling solar radiance to electricity conversion and an electrical driver interface for implementing electrical characteristic of power limited systems in power simulations.

The article considers promising areas of green tourism development in Vinnytsia region. Describes a number of extremely unique and interesting objects that are little known to tourists. These include the «Illinets astroblem» ˗ craters at the site of a meteorite fall 400 million years ago. The crater is located between the villages of Ivanky, Lypovets district and Luhovo, Illinets district. They arose as a result of the fall to Earth of a cosmic body with an approximate weight of 40 million tons. The diameter of the meteorite is about 230 - 300 m. At the time of the fall, the meteorite was divided into 3 parts. As a result, 13 craters appeared. The largest of them have diameters of 7-10 km. According to experts, the initial depth of the largest crater was about 800 m. The local places are witnesses of a unique phenomenon of planetary scale and are interesting for the tourist business. There are no analogues to Ilyinets Crater in the world. The problems of exhaustion of traditional energy sources are analyzed, and in this connection the inevitable increase in their price. The necessity of wide introduction of alternative energy in the field of green rural tourism is proved. The use of autonomous, network and hybrid solar semiconductor power plants is. promising. Grid-connected solar power plants as an object of solar energy can be used both to generate electricity for household consumption and for the purpose of further sale to the national grid at a green tariff. It is shown that the introduction of solar energy by tourism businesses significantly increases their profits and competitiveness, reduces electricity costs, significantly improves the quality of services, increases the level of tourist service in rural areas. The need for state support and investment for the development of renewable energy sources in rural areas and green rural tourism is substantiated.

This paper aims at an investigation of factors of differentiation of basic social and economic characteristics of foreign immigrants in the Region of Western Greece. The paper explores whether the thesis of urban-rural divide is relevant for the differentiation of immigrants’ socio-economic characteristics in a typical Region of Greece, where there is a strong interplay between major urban centers and large rural areas. Findings show that spatial factors play a very limited role in the differentiation of socio-economic characteristics of immigrants and indicate that other factors are more important. Thus, and as regards socio-economic characteristics of immigrants, the overall picture is that of urban-rural continuum rather than divide.

Solar has become one of the fastest growing renewable energy sources. With the push towards sustainability it is an excellent solution to resolve the issue of our diminishing finite resources. Alternative photovoltaic systems are of much importance to utilize solar energy efficiently. The Cu-chalcopyrite compounds CuInS2 and CuInSe2 and their alloys provide absorber material of high absorption coefficients of the order of 105 cm-1. Cu2ZnSnS4 (CZTS) is more promising material for photovoltaic applications as Zn and Sn are abundant materials of earth’s crust. Further, the preparation of CZTS-ink facilitates the production of flexible solar cells. The device can be designed with Al doped ZnO as the front contact, n-type window layer (e.g. intrinsic ZnO); an n-type thin film buffer layer (e.g. CdS) and a p-type CZTS absorber layer with Molybdenum (Mo) substrate as back contact. In this study, CZTS films were synthesized by a non-vaccum solvent based process technique from a molecular-ink using a non toxic eco-friendly solvent dimethyl sulfoxide (DMSO). The deposited CZTS films were optimized and characterized by XRD, UV-visible spectroscopy and SEM.
