It is well-known that, in the past decades, the burning of fossil fuels was identified as the major cause of climate change. Climate change mitigation is becoming a central concern of global society. Limiting global warming to below 2 °C above the temperature of the pre-industrial period is the key to preserving global ecosystems and providing a secure basis for human activities, as well as reducing excessive environmental change. The ambitions increased at an accelerated pace with a dramatic expansion of net zero-emission targets. Increasing pressure from citizens and society has forced countries to intensify their climate plans, while the private sector has bought a record amount of renewable energy. An energy system based on fossil fuels must be replaced by renewable energy with low carbon emissions with improved energy efficiency. That applies to all consumers of fossil energy: cities, villages, building sectors, industry, transport, agriculture, and forestry. The paper explores and presents the strategy of energy development of renewable energy sources in the world. The application of new technologies that have led to developing renewable energy sources is presented in detail: wind energy, solar energy, small hydropower plants, biomass, and their increase in the total share of energy production, i.e., reduced fossil fuel use in energy production. Investments in new technologies used in renewable energy sources have led to increases in employment worldwide. Analysis of the trend of increased energy production from RES (Renewable Energy Sources) with investment plans, the employment rate for each energy source, and the development of renewable energy sources in the coming period are provided.

Energy stability and security have become one of the most important issues in recent years on planet Earth. Nowadays, worldwide economic, industrial and social development is related to the energy and energy-system that provided great benefits to a society, but the society is paying a high price because of the production and emission of carbon dioxide and other greenhouse gases into the atmosphere. There are numerous climate changes, which pose a threat to each continent, disorder in agriculture, disorder in food production, floods and fires, as well as changes in the ecosystem. Energy stability and security have become one of the most important issues in recent years. Energy is essential for development of any country, notably when it comes to its industry and economy. Without adequate policy operations of the energy sector, it is not possible to achieve industrial or economic progress. Nevertheless, no matter how important energy is for the development, it is only a mechanism for achieving the ultimate goals – sustainable economy, clean environment, high standard of living, prosperity and health of the population. This paper elaborates on and outlines a strategy for energy development of renewable energy sources in the world, as well as in the European Union. It presents in great details the application of new technologies that have led to the development of renewable energy sources: wind-power, solar energy, small hydro power plants, biomass, and their increase in the overall participation of energy production and reduction of fossil fuels in energy production. Investing in new technologies which use renewable energy sources have led to the increase in employment in the world, so that about 6.5 million people in the world have been employed until today. This paper outlines the trend of increasing energy production from RES (renewable energy sources) by investing in any of the abovementioned energy sources, as well as employment for each energy source in the world and the EU-28. Also, the development of renewable energy sources in the future has been presented.

Originally, coal was the main source of energy. It remains so throughout the 18th century during the period of the rapid industry development. Later on, oil and naphtha began to be used as energy sources and their usage expanded especially in 19th century. A special feature of the above mentioned fossil fuels is their long creation period – requiring millennia. They are a result of rotting of different plant and animal kinds. In comparison to the period of their formation, the period of their utilization is far shorter. In accordance with a number of existing statistics about 2050 year it may be talked about a depletion of the liquid fossil fuels, also, the world coal supplies are considered to last within the next 200 years. Therefore, the development of nuclear power engineering is considered to be one of the alternatives to generate energy. Recently, the nuclear power energy generation has been denied in many countries because of the risks associated with its generation and because these risks have been confirmed by serious accidents throughout the World. The storage of worked nuclear waste is also a problem and risky. The renewable energy sources are another possibility to generate energy.

Abstract Examining willingness-to-pay (WTP) for renewable energy sources (RES) as well as views on energy topics can enable policymakers to design effective measures for facilitating the transition from fossil fuels to a renewable-based energy system. The aim of this study was to investigate environmental students’ willingness-to-pay for renewables and their views on various energy topics. Results showed that respondents preferred renewable-based electricity production to conventional energy production while solar energy emerged as the most preferred renewable type. In addition, most respondents were willing to pay for renewable energy but would pay relatively low sums of money per month. Moreover, respondents were divided over whether new lignite plants should be constructed in Greece. Finally, social media and special websites were the most favored media of daily information.

Decentralized Energy

Until recently, the prevailing idea was that for the functioning of the energy system it is necessary to be composed of large plants and for energy to move from the centre of production to cities and places of consumption. With the advent of decentralized energy production systems and new technologies for their use, the original model is changing more and more. EU Directive 2018/2001 on the promotion of the use of renewable energy sources (RES) designates “prosumers”, i.e. at the same time both producers and consumers of renewable energy, as well as RES communities, while EU Directive 2019/944 introduced the term “citizen energy communities”, i.e. civil energy communities, provided that this Directive, in addition to the distributive production of electricity from RES, also includes electricity from other sources. EU member states are obliged to adopt their own regulations regarding the implementation of the directives, and after that the appropriate incentive measures. The Energy Communities initiative offers citizens new opportunities in terms of active involvement in energy issues. As they are decentralized RES-based projects, they promote the practice of sustainable energy production and consumption, as well as energy storage and exchange within the community. Traditionally passive consumer becomes an energy “prosumer”, a co-owner of a RES plant and a member of the energy community. There are thousands of so-called RES cooperatives in Europe, which are the most common organizational form of energy communities and can play an important role in the process of decentralization of the energy system. The transition to decentralized energy production has many advantages, namely: the use of local energy sources, increased security of local energy supply, shorter transport distances and reduced losses in energy transmission, encouraging community development and creating local jobs. The purpose of this paper is to bring closer to the general public in Serbia the concept of energy communities, what they are and what their role is, with most of the work dealing with energy communities in the EU.

Abstract The increase in population and urbanization which emerged together with industrialization have brought the increase in energy demand with them. Carbon emissions rise as a result of the increase in energy demand and lead to climate change. Such changes in climate have negative effects on not only the environment but human life as well. Therefore, countries should implement energy policies with low carbon density in order to reduce greenhouse gas emission. In this context, preferring renewable energy sources can prevent temperature increase by reducing the effects of fossil fuels on the environment. Turkey should attach importance to renewable energy sources and invest in these sources in accordance with the commitments accepted at the Paris Climate Summit in order to reduce carbon emission.

В процессе формирования культуры безопасности и экологического мировоззрения средствами имитационного моделирования у студентов вузов преподаватель играет важную роль, прежде всего, через создание им соответствующих дидактических условий для побуждения студента к эффективному достижению учебных целей. Под такими дидактическими условиями мы понимаем факторы, а также обстоятельства, которые действуют в учебно-воспитательном процессе и влияют на учебную деятельность студентов. Глобальный спрос на энергию все время увеличивается. Поддержание энергетической безопасности и создание низко-углеродного будущего являются ключевыми задачами, и возобновляемые источники энергии играют жизненно важную стратегическую роль в удовлетворении энергетических потребностей сейчас и в будущем. Почти две трети чистого прироста мировых энергетических мощностей в течение следующих лет будет приходиться на нетрадиционные возобновляемые источники энергии. Возобновляемая энергия - это энергия, полученная из природных ресурсов земли, которые не являются конечными или исчерпываемыми, таких как ветер и солнечный свет. Возобновляемые источники энергии являются альтернативой традиционной энергии, основанной на ископаемом топливе, и, как правило, они гораздо менее вредны для окружающей среды. In the process of forming a safety culture and an ecological worldview by means of simulation modeling among university students, the teacher plays an important role, first of all, through the creation of appropriate didactic conditions for encouraging the student to effectively achieve educational goals. Under such didactic conditions, we understand the factors and circumstances that operate in the educational process and affect the educational activities of students. The global demand for energy is increasing all the time. Maintaining energy security and creating a low-carbon future are key challenges, and renewables play a vital strategic role in meeting energy needs now and in the future. Almost two-thirds of the net increase in global energy capacity over the next years will come from unconventional renewable energy sources. Renewable energy is energy derived from the earth's natural resources that are not finite or exhaustible, such as wind and sunlight. Renewable energy sources are an alternative to traditional energy based on fossil fuels, and, as a rule, they are much less harmful to the environment.

This research work is devoted to the issue of studying the key risks of switching to renewable energy sources. The relevance of the topic of work is determined by the fact that, according to climatologists [5], climate change, which has a negative impact on the environment, is caused by the emission of greenhouse gases such as carbon dioxide (CO2). For this reason, measures to prevent or reduce greenhouse gas emissions are at the heart of the energy transition. International treaties such as the Kyoto Protocol and the Paris Agreement lay the foundations for global action to combat climate change and implement a fourth energy transition. The energy transition is characterized by a number of incentives and barriers. Despite the fact that there are many scenarios for the development of the global energy sector by 2050, the expected transformations of the energy market lead to a significant redistribution of the ratio of the shares of hydrocarbon sources and renewable energy sources [16]. The trend towards fossil fuels is on the rise. These transformations in the market are determined not only by the climate agenda, but also by the concept of sustainable economic development.

Abstract In this study, the authors carried out a detailed analysis of the technologies required for successful implementation of a sustainable renewable energy household power supply in Papua New Guinea or PNG (PNG is a Pacific Island nation, North of Australia) to free the country from fossil fuel dependency. The role of renewable energy sources in the recent PNG National Energy Policy covering 2018 to 2050 (unveiled at the 2018 March Energy Summit in Port Moresby by the PNG Minister of Energy) was also analysed. From the outcome of our recently concluded SERI 2018 Renewable Energy conference, we assembled into a single hypothetical ‘energy basket’ all the varied renewable ‘green’ energy sources within PNG (as estimated by our energy research groups). This paper estimates that there is sufficient renewable energy in PNG and advocates that these available green energy sources should be tapped, for they can go a long way in the quest for climate change mitigation. This research paper will articulate that shifting PNG’s and other Pacific Island nations’ energy reliance from fossil fuels and other non-renewable sources to renewable green and environmentally sustainable sources is not only achievable, but feasible within a reasonable time.
