  Increasing air pollution and global warming due to the excessive use of fossil fuels attracted public attention to climate change. Accordingly, the expected increase in demand for other alternative energy sources especialy renewable energy is predictable. While some research on renewable energy shows that these kind of energy also have undesirable environmental effects. In this study solar energy systems, wind power and hydroelectric power systems wew investigated and their effects on air, soil, sound and effect on wildlife were studied. The results show that although these kind of energy are called clean energy, they have negative environmental effects. This research also suggests ways to prevent the effects of destructive renewable energy sources. Manuscript profile

  Sustainable urban development is about building a relatively ideal and ideal city in which contemporary citizens enjoy a fairly good life and the future generation's ability to meet their needs. Tehran, as the main city in Iran, which has about 20% of the country's population and its changes are influenced extensively and directly throughout the country, should therefore be considered more than other cities in terms of urban development. This research is practical in terms of purpose and in terms of its type, descriptive-analytical and consists of four main stages. In the first phase of this research, in order to identify and assess the current status of produced and consumed energy, we study and compare energy consumption data from all fossil fuels, non-renewable and renewable energy sources. In the second stage, the solar energy potential in Tehran, was studied using the information obtained from the synoptic station Mehrabad. In the third step, the cost of generating energy (electric energy) with fossil fuels or photovoltaic systems was compared. In the final stage, the process of designing and analyzing the choice of photovoltaic systems with run on two sample systems was implemented. The results indicate that the domestic, commercial and public sectors and transportation have the highest energy consumption in Tehran in different parts of the country. And also these two parts form the main part of energy consumption in residential areas. as of 2014, the total supply of energy (including production, imports, ...) of non-renewable fossil fuels is 1.774.5 million barrels of crude oil. As of 2014, the total supply of energy (including production, imports, ...) of non-renewable fossil fuels is 1.774.5 million barrels of crude oil. By contrast, the total supply of renewable energy, especially solar energy, is only 24.9% (equivalent to crude oil barrels), which is only 0.013% of the total energy supply of the country. However, due to high capacities of different energy standards in Tehran, utility rate of solar energy this city is significant. And luckily, in recent years, there has been a downturn in the cost of photovoltaic systems. Therefore, at the end of the research, suggestions were made to enhance the role of solar energy in the sustainable development of Tehran, especially in the construction industry, contains: review and modification of urban planning rules for optimizing energy consumption of fossil fuels, by notification and coercion new guidelines for the use of solar energy in the residential areas of Tehran. Culture -building and development of incentive schemes for the prosperity of the production and use of solar energy by citizens, even in small quantities. Providing necessary infrastructure for utilizing solar energy in the household, public and commercial sectors of Tehran Manuscript profile

  Solar energy is one of the most important types of new and renewable energy that, if it replaces fossil fuels, can end existing concerns about the end of life as well as environmental pollution caused by fossil energy carriers and price fluctuations and energy crises. Considering the high potential of solar energy in large areas of Iran, among energy sources, solar energy is more attractive for researchers. Today, many countries use solar power plants in grid-connected and grid-independent formats. The use of renewable energies is due to the reduction of dependence on oil and gas, sources that are less harmful to the environment, being cheap, permanent, clean, reducing fossil fuel consumption and reducing greenhouse gases, the ability to be used at home and on a large scale, and easy maintenance are some of the advantages of using renewable energy. They are from solar and wind energy, which have turned these features of renewable energy into the best and cleanest energies. Manuscript profile

  The practical efficiency of commercial m-Si and CIS PV modules measured in reality by our group was less than 15% due to the higher temperature of the PV modules, and the rest is more than 85% of the exhaust solar energy. Environmental Heating It was previously reported in 2020 that the principle of an environmentally friendly PV/T (photovoltaic/thermal) solar panel using m-Si PV module to use 71.3% of solar energy for electricity and 40°C water This panel was designed to confirm the principle, that is, it was an experimental PV/T solar panel. In this paper, a new environmentally friendly PV/T solar panel for use in BIPVT (photovoltaic) systems is presented. /integrated heating in the building) is proposed. The new panel uses a CIS PV module and all functions, including the heat exchanger using aluminum flat tubes, are housed in a panel box that is approximately the size of a simple CIS PV panel. PV/T Solar Panel Proposed 73.5 % of solar energy with 13.0% power generation efficiency and 60.5% heat collection efficiency in a 40°C hot water source in Yokohama, Japan. The efficiency is higher than the previous test panel. The proposed panel can also suppress heat radiation around 50°C even in the case of hot water of 60°C. The proposed PV/T solar panel can meet all residential thermal needs such as domestic hot water (DHW) and space heating or cooling using solar heat with less environmental heat load.
