Regional Sustainable Development

In this paper, the author focuses on the fundamental hypothesis that the adoption of a concept of regional sustainable development and the use of renewable energy sources are preconditions to organising an acceptable regional tourism offering based on an eco-philosophy The renewable development of tourism regions is the basic framework for research regarding opportunities for introducing renewable energy sources such as hydro energy, wind power, solar energy, geothermal energy, and biomass energy. The purpose of this paper is to indicate the real opportunities that exist for substituting conventional energy sources with renewable ones and the role of renewables in regional development from economic, environmental and sociological viewpoints. It should also be noted that renewable energy sources have a strong regional importance and can contribute significantly to local employment.

Electricity generation, one of the renewable energy sources (RES), delivers a solution for various problems such as energy efficiency, energy supply security, reducing foreign dependency, and especially, environmental concerns. However, the solutions provided for these problems bring along the question of which RESs are produced more effectively. Therefore, in this research, RESs used for electricity generation in Turkey were analyzed by using generation data to show which one is more effective. Bi-objective multiple-criteria data envelopment analysis (BiO-MCDEA) method, a goal programming-based efficiency determination method, was used for the efficiency analysis conducted for five years between the years of 2014 and 2018. As a result of the analysis, geothermal energy came into prominence as the most effective RES for all of the years included in the solution. Geothermal energy was followed by biomass energy, wind energy, hydroelectric, and solar energy, respectively.

The energy problem is one of the most pressing issues in the world  is on the agenda of scientists working in the field of energy.  XXI  century with the development of science, rising technology creating the opportunity for a person to live normally, providing him with enough energy, food is one of the key issues.  Everyone knows digging  the energy reserves of its resources are declining.  But the need for it increased, and now the world's population has reached seven billion. There are the following types of energy sources that used by humanity: oil, coal, gas, atom, biomass, water, solar, wind, geothermal energy.  This energy sources can be divided into two types, respectively.  Biomass, water, sun, wind, geothermal energy - renewable;  oil, coal, gas, nuclear energy - non-renewable.  The energy from these resources is electricity, utilities such as energy consumed for services (heating of buildings, hot water supply) occurs in views.

Renewable energy sources are now essential to establish sustainable development. This paper examines one kind of source the geothermal energy. For geothermal energy when combined with a heat pump COP can be used for evaluation. For solely geothermal sources different approach is needed thus in the paper, a new geothermal heat production coefficient is used to examine the operational feasibility. For the assessment, many hypothetical buildings were created to model their heat demands. Two types of calculation methods are used for heat demand calculation. Based on the results, the maximum depth of a geothermal borehole and economically critical qualitative coefficient was concluded.

Objectives : The world is getting more polluted day by day and living conditions are getting harder and harder. The Covid 19 process explains this situation even better. Global warming will show its effect more heavily if measures are not taken. There is a close relationship between global warming and the type and method of energy used. The use of fossil fuels by people pollutes the environment too much, and the use of alternative energy sources is gaining importance instead. Here, the issue of use and management of renewable energy sources comes to the fore. Turkey is a country with rich renewable energy resources and experience in cooperatives. In this study, it is aimed to reveal the current situation and problems of renewable energy cooperatives, which can be a model for managing Turkey’s renewable energy resources.Methods : In the study, a literature review method was used by examining domestic and foreign resources related to renewable energy and renewable energy cooperatives. Some of the data obtained were arranged in tables and used in the study.Results and Discussion : It is very important for Turkey to develop renewable energy resources and increase the share of renewable energy resources among other resources. Because Turkey is a developing country and its population is increasing day by day. It is essential to use renewable energy for the energy need of the increasing population and the least environmental pollution. Within the scope of 2023 targets in Turkey, it is planned to produce 34 thousand MW of hydroelectric, 20 thousand MW of wind energy, solar energy, 5 thousand MW, 1,000 MW of geothermal energy and 1,000 MW of geothermal energy and biomass energy. In order to achieve this goal, it is planned to invest approximately 60 billion dollars in renewable energy sources. Cooperatives are one of the most effective ways in which Turkey can use its renewable energy resources. Because cooperative is a method known to the Turkish society and it would be beneficial to transfer it to the renewable energy field.Conclusion : Turkey is a developing country and its energy needs are increasing day by day. It is very important to use the renewable energy resources it has correctly and in a planned way. In this respect, it should be understood that renewable energy cooperatives are quite compatible with Turkey. Turkey should provide the necessary legal and administrative structure for the development of renewable energy cooperatives and develop it with financial support in order to make its increasing energy needs sustainable.
