Abstract Renewable energy is one of the alternative energy resources in Malaysia to replace fossil fuel use, which is an important issue that needs to be established. Some of the possible renewable energy sources are wind, hydro and solar. Since 2019, various incentives announced by the Malaysian Ministry of Energy and Natural Resources (KeTSA) to enhance renewable energy development which is in line with Government Energy policy. However, today, in contrast to the participation of investors and international contractors, the presence of entrepreneurs and domestic workers in this sector is feeble. In this regard, the Technical Vocational and Training (TVET) institution is seen to have the potential to minimize this crisis by creating competent, skilled and competitive electrical entrepreneurs for the field of renewable energy. This paper explores the ability of TVET electrical entrepreneurs to participate in renewable energy businesses. Based on the literature on energy entrepreneur development, it was found that the TVET electrical entrepreneur faces four challenges, namely financial, technology costs, logistics and government support. The proposed future development of renewable energy is in Mini-hydro and solar photovoltaic (PV), while wind power does not seem viable to TVET electricity entrepreneurs.

Renewable Energy Development

For Ukraine the issue of renewable energy development is extremely relevant in view of energy (increase in energy independence), economic (reduction of energy resources import costs), environmental (reduction of environmental pollution) and social (improvement of energy supply, increase in income of the population) problems that can be solved at its expense. Based on the existing potential, if there exist adequate mechanisms of government support for the renewable energy development, Ukraine may increase the share of renewable energy sources in the energy balance up to 25% by 2035, reducing to import a significant share of energy resources. In order to justify the economic feasibility of investing in households’ renewable energy projects until 2029 and to identify the promising trends in this sector development in Ukraine, the authors have assessed the economic efficiency of a project of 10 kW solar power plant construction in a typical Ukrainian household under some conditions. The results have shown that it is expected to observe a gradual outflow of investments from renewable energy sector of households since 2022-2023 due to the decrease in feed-in tariff rates and a corresponding decrease in the profitability of private renewable energy projects with small power capacities. Therefore an alternative powerful state support will be needed to provide the development of renewable energy sector.

Abstract. The modern world, including highly developed countries, which focus a significant part of their financial flows on increasing environmental capacity with propaganda and a call to stop global warming, quite openly demonstrates its commitment to replenish and restore «green» reserves. Today, in the system of economic relations and financial support of Ukraine’s economic development, the involvement of the environmental component of such development is becoming increasingly important. When studying alternative energy sources as a relatively new way for Ukraine, it was found that the development of such energy affects a number of socio-economic factors, including transport, environment, health and nutrition, agro-industrial management, energy, etc. Government support, support, support and formation of a general strategy for the development of investment in alternative energy should become a priority in increasing the greening process in the country. The only conceptual approach to ensuring the development of «green» energy is a guarantee of establishing a mechanism to ensure the investment potential of the direction. For the effective functioning of renewable energy sources (RES) it is necessary to bring national legislation in line with international requirements, in particular to international acts of the European Union. Creating optimal guarantees and providing quotas for investors. Necessary conditions for development are: development of software and technical and technological support not only for the generation, accumulation and use, but also the accumulation and generalization of information, accounting, analysis, control over the consumption and sale of such energy; innovation and investment support at the level of deepening and expanding research, creating work programs, projects and groups; institutional support for attracting investment in the development of «green» energy, development of a state target program for the development and support of RES.

Native American reservations are among the most economically disadvantaged regions in the United States; lacking access to economic and educational opportunities that are exacerbated by “energy insecurity” due to insufficient connectivity to the electric grid and power outages. Local renewable energy sources such as wind, solar, and biomass offer energy alternatives but their implementation encounters barriers such as lack of financing, infrastructure, and expertise, as well as divergent attitudes among tribal leaders. Biomass, in particular, could be a source of stable base-load power that is abundant and scalable in many rural communities. This case study examines the feasibility of a biomass energy plant on the Cocopah reservation in southwestern Arizona. It considers feedstock availability, cost and energy content, technology options, nameplate capacity, discount and interest rates, construction, operation and maintenance (O&M) costs, and alternative investment options. This study finds that at current electricity prices and based on typical costs for fuel, O&M over 30 years, none of the tested scenarios is presently cost-effective on a net present value (NPV) basis when compared with an alternative investment yielding annual returns of 3% or higher. The technology most likely to be economically viable and suitable for remote, rural contexts—a combustion stoker—resulted in a levelized costs of energy (LCOE) ranging from US$0.056 to 0.147/kWh. The most favorable scenario is a combustion stoker with an estimated NPV of US$4,791,243. The NPV of the corresponding alternative investment is US$7,123,380. However, if the tribes were able to secure a zero-interest loan to finance the plant’s installation cost, the project would be on par with the alternative investment. Even if this were the case, the scenario still relies on some of the most optimistic assumptions for the biomass-to-power plant and excludes abatement costs for air emissions. The study thus concludes that at present small-scale, biomass-to-energy projects require a mix of favorable market and local conditions as well as appropriate policy support to make biomass energy projects a cost-competitive source of stable, alternative energy for remote rural tribal communities that can provide greater tribal sovereignty and economic opportunities.

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

The rapid development of industry causes the need for fuel and energy to increase, especially fossil fuels (petroleum). This has the effect of an energy crisis. Biomass is of particular concern as one of the renewable energy sources to address the current energy crisis.  Biomass consists of hemiselulose, cellulose, and lignin that can be converted into liquids (bio-oils) of pyrolysis. One of the wastes that can be converted into bio-oil is tobacco waste. Tobacco waste is produced by more than 2 million tons eachs. The waste has the potential to be further processed into bio oil using fast pyrolysis method with efficient and quality bio-oil manufacturing measures. The bio-oil results from tobacco waste using the fast pyrolysis method have values of carbon, hydrogen, nitrogen, oxygen and other organic compounds and the H/C ratio is greater than the yield of tobacco waste bio-oil using the low pyrolysis method. Where the bio-oil of tobacco waste using the fast pyrolysis method has a high heating value equivalent to the distribution of hydrocarbons from biodiesel, which means it has the potential as an alternative energy to replace petroleum. The potential as a substitute fuel for petroleum must also be balanced with fast and efficient production, maximizing bio-oil production by selecting the reactor and the optimum temperature usedKeywords: Waste, Tobacco, Bio-Oil, Renewable Energy, Fast-pyrolisis

Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes. Many countries have made significant progress in the development of renewable energy.
