The aim of this paper is to analyze renewable energy sources (primarily untapped biomass potentials) in the Autonomous Province of Vojvodina in the Republic of Serbia, which, when used for energy purposes, could significantly reduce energy dependence on fossil fuels. The idea of using biomass in Vojvodina emerged about ten years ago, but it is estimated that currently only 5% of total biomass potential, the most significant source of renewable energy in the region, is being used. This paper re-emphasizes the idea of focusing Vojvodina’s energy policy on its own energy resources, which are readily available and renewable, but each year is either burned in the fields or left to rot. The paper will outline the total potential of raw materials, the form in which they are found, and the possible means of utilizing them. It will also provide an overview of energy in Vojvodina with a particular focus on the portion of renewable sources as a neglected potential within overall energy consumption. In addition to energy potential, this paper also points to the benefits for heating and the environment that would be created through increased use of biomass in the process of energy production.

In this paper, an attempt is made to answer the question: Can renewable energy sources eventually supply India’s electricity needs in the future? In particular, we examine the total potential of renewable energy sources in India and extent to which they can supply these needs. The estimates made here indicate that even with a frugal per capita electricity need of 2000 kWh/annum and a stabilized population of 1500 million by 2025, India would need to generate approximately 3000 TWh/yr. As opposed to this, a systematic analysis of the information available on all the renewable energy sources indicates that the total potential is only around 1000 TWh/yr. It is concluded that in the future as fossil fuels are exhausted, renewable sources alone will not suffice for meeting India’s needs.

Today, almost all of civilisation is based on energy. To a large extent, energy is being continuously acquired from non-renewable raw materials deposited in the Earth’s crust. Renewable sources provide alternative, infinite energy resources, particularly solar radiation, wind power and water movement. The Paris Agreement envisages the complete abandonment of fossil fuels by the year 2050 for all EU Member States. From a technical point of view, a complete transition to renewable energy sources (RES) is very difficult to achieve. In the case of Poland, the way to 100% RES is longer and more complex than in most EU countries. The main purpose of the conducted analysis was to thoroughly assess the possibilities for obtaining energy from inexhaustible sources as well as the benefits of various procedures in order to develop an optimal set of solutions. The aim of the presented study is to indicate the possibilities for the development of construction investments in the field of renewable energy sources that have an inseparable impact on spatial management. To achieve this aim, the method of research of the available literature and legislation was applied.

This paper presents the results of calculations to reduce greenhouse gas emissions in agricultural sectors of the Republic of Uzbekistan within the framework of the project: “Sustainable Agriculture Development and Climate Change Mitigation”. The initial data were the characteristics of the implemented installations based on renewable energy sources for the period of 2014-2018. Most of these installations were biogas settings based on the principle of anaerobic fermentation, as well as solar water heating and photovoltaic stations. The calculations were performed according to the “AMS-III.D” and “AMS-I.J” methods by the “Global Environmental Fund” experts. The developed computer programs were applied to calculate the arrival of radiation and the duration of sunshine during the year on the territory of Uzbekistan. According to the calculations, the reduction of greenhouse gas emissions was 1338840.5 tons of CO2 for the indicated period during the operation of installations based on renewable energy sources. Within the framework of this project, the total potential of generating electric energy from biogas settings and solar photovoltaic stations at the amount of 10,424 MWh was estimated.

Currently, marine transportation in the world still uses fossil fuels. In addition to running low on supplies, fossil fuels also cause emissions that cause global warming. Sea transportation generates around 1,000 million tonnes of CO2 emissions. Therefore, the exploration of alternative energy is becoming a popular research direction. Several renewable energy sources include solar and wind energy. Indonesia has an average wind speed of above 8 m/s at sea. Also, the energy potential of the sun is around 4.8 kWh/m2. Based on the potential of these renewable energy sources, this study discusses the potential of renewable energy sources from sunlight and wind, which are implemented in the prototype catamaran ship. The results obtained from the experiment, the total energy of photovoltaic (PV) and wind turbine generators is 774 Wh. This energy can be used to charge a battery with a battery specification of 35Ah for 6 hours.

AbstractThe paper analyzes the development opportunities of solar systems in the Republic of Serbia. Renewable energy sources and their energy potential, such as solar energy, should be considered in order to meet the needs of consumers. Solar energy can be considered the most modern renewable energy whose utility is still developing, and it is not represented as the utilization of hydro energy sources. Researches show that Serbia is a country with a high RES potential and that it has favorable conditions for production of electrical and heat energy from renewable sources. The aim of this paper is to present the possibilities of using solar energy in Serbia. Energy supply from renewable energy sources is a key factor for each country's strategy, because it directly contributes to reducing the negative effect on the environment.

There have been many discussions in Lithuania about a strategy for reducing the impact of climate change. Members of the international community agree that reducing greenhouse gas emissions to the atmosphere is necessary to avoid dangerous climate change. The main greenhouse gas emissions from human activity are carbon dioxide. Carbon dioxide is mainly produced by combustion of fossil fuels, which are currently used: natural gas, coal, oil, peat, etc. Fossil fuels are still the main source of energy. The amount of energy produced and consumption from renewable energy sources (RES) is increasing both in Lithuania and in Europe. According to the Directive (2009/28/EU) Lithuania has a legally binding target in the year 2020. The share of renewable energy would account for at least 23% of the total final energy consumption of the country. The share of renewable energy would account for at least 10% of the final energy consumption in the transport sector. Lithuania achieved its target and this indicator was 23.9% in 2014. According to the Eurostat data, the share of RES produced from renewable energy sources in the total energy balance is increasing annually. In 2007 this indicator was only 4.7% and it has grown 4 times in 2016. The production of electricity from renewable energy sources satisfied the country’s energy demand by 18.9% in Lithuania. This is the best index so far. Wind energy is the most popular type of green energy, which has been growing at a rate of 5 times in this period. Promotion of the use of renewable resources is provided in the Republic of Lithuania Law on Renewable Energy and the long-term development of the use of renewable resources is provided for in the National Energy Strategy. At this moment Lithuania is a fuel importing country, but in the future Lithuania should produce about 70% of electricity itself. It is forecasted that in 2020 electricity generation in the country should make up 35% of the demand, in 2030 it should be 70%, and in 2050 it should reach 100%. From renewables we should receive a large, almost 80% share of energy. And gas will be a transitional fuel by 2050. The project of strategy states that energy from renewable sources will become a major component of all sectors: electricity, heat, cooling and transport. The objective is to achieve a 30% share of renewables in the final energy consumption balance in 2020, 45% in 2030, and 80% in 2050. The renewables should produce all heat energy and the share of green energy in transport should reach 50% at the end of 2050. The article focuses on the use of the potential of renewable energy sources from agricultural raw materials and their waste. The surplus of agricultural production makes it necessary to look for opportunities to reduce environmental pollution. The aim of the article is to assess the use of potential of renewable energy sources in Lithuania. The results of the analysis showed that increasing energy production is possible not only using wind, solar, water or geothermal energy, but by processing traditional agricultural and animal products and their waste: straw, grain crops, livestock or bird’s excrement, etc. It is recommended to look at the unconventional potential of raw materials, such as sewage sludge, spirits, molasses, etc. The use of biomass has potentially revealed alternatives to biofuels that underpin the use of different generations of biofuels. The use of biofuels in the long term should contribute to the slowdown in climate change.
