It is of great importance to save energy and use low-carbon production methods in industrial enterprises, as they reduce the carbon footprint of enterprises. In this study, it is aimed to evaluate the energy efficiency applications that can be made in 2 factories operating in the food and automotive sectors in Turkey and to reveal the energy savings (Nm³ / year) to be achieved with these applications and the amount of carbon emissions to be prevented (ton CO2 / year). Common improvements that can be made in both facilities are insulation application to hot lines, elimination of compressed air leaks, reduction of compressed air system pressure by 1 bar, regulation of compressor intake air, application of solenoid valve and flash steam application. In addition to these, 2 individual energy saving studies have been proposed in the food business and 1 in the automotive sector. While it is seen that the most efficient application in terms of environmental benefit (48 tons CO2) and energy saving efficiency (22 TOE/year) in the food sector is flash steam application, in the automotive business it is seen that the compressed air leaks are eliminated (152 tons of CO2) and hot air is used in terms of energy saving efficiency. Insulation application (60 TOE/year) to the lines has been determined as the most advantageous application. When all the suggestions are evaluated, as a result of 6 applications in the food business, a total reduction of 121 tons of CO2 emissions can be achieved annually, while this value will be at the level of 323 tons in the automotive business where 5 improvements are proposed.

Today, increasing energy costs bring the efficient use of energy to the agenda in the textile sector as well as in all sectors. The use of renewable energy sources in the production process will continue to occupy an important place in energy production as it is an inexhaustible and domestic energy source with low cost values compared to traditional fuels. Solar energy maintains its importance as the most preferred renewable energy source for domestic and industrial use due to its high potential. In this study, grid-connected and off-grid photovoltaic system designs were carried out using the HOMER Pro program in order to meet the electricity needs of a textile factory located in Bursa Demirtaş Organized Industrial District (DOID). As a result of the study, it was decided that the off-grid photovoltaic system was the most suitable system for the factory, and the net present cost of the system to be installed was determined as 2,625,139,000 TL ($ 151,654,477.2) and the simple payback period was determined as 14.04 years).
