Nowadays, renewable energy utilization plays a key role in developing countries to fulfill the additional energy requirements of a country and reduce dependency on fossil fuels and traditional biomass consumption. As Myanmar has an agriculture-based economy and 48% of forest-cover (32.2 million hectares); biomass is one of the major renewable energy sources, contributing around 50% of total energy consumption. Therefore, the study aimed to highlight the available biomass sources and energy potential for the energy sector in Myanmar. In order to achieve the aim, the study collated the types, quantity and qualities of biomass resources, and energy utilization around Myanmar. Besides, the study synthesized and evaluated the energy potential of the major biomass resources coming from the agriculture sector, forest sector, livestock and poultry sector, and municipal sector. It was estimated that the total energy potential of the major biomass sources amounted to approximately 15.19 million tons of oil equivalent (Mtoe) in 2005 and 17.29 Mtoe in 2017, respectively. The unexploited biomass energy potential around the country was estimated to be nearly 50% higher than that of the projected biomass energy utilization during 2015–2019. Finally, the study concluded with recommendations to provide the future sustainable development of biomass energy in Myanmar.

Abstract Biomass is an essential pillar of the bioeconomy as it serves as its main resource. Biomass energy plays an important role in energy sector. According to long wave theory, a sharp breakthrough in biotechnology is due over the next few years. As the price for energy wood increases, wood as a resource will not be sustainable in energy sector. In the case of Latvia, the price of energy wood as a resource is predicted to increase from 0.04 EUR/kWh to 0.12 EUR/kWh per unit of energy.

According to almost all estimates, significant investments in new renewable energy sources in Serbia are needed. Serbia has economically viable potentials of renewable energy sources (RES) (solar energy, wind energy, hydropower, biomass energy, geothermal energy, etc.), so the structure of the production mix in the electricity system should increasingly be based on renewable sources. In this paper, an attempt is made to answer the following questions: does Serbia need new production capacities, does Serbia need new production capacities from RES, and finally, which of the RES would be the most suitable at the moment? The paper assesses whether this is exactly the right moment to accelerate the process of energy transition in Serbia, as well as the opportunity to ensure a more sustainable growth and development through a faster transition to RES. It starts from the fact that increasing the production of electricity from RES, together with measures to increase energy efficiency and decarbonize energy production and consumption, is the backbone of the energy transition and at the same time the essence of Serbia's commitments by joining the Energy Community and accepting international climate agreements. The paper assumes that by increasing the efficiency of the energy sector and use of RES, European policy goals can be achieved in Serbia and that energy sector can be positioned as an engine of stability and sustainable economic development. Secondary effects will lead to increased sustainable employment, reduced public debt and increased competitiveness of the sector. Therefore, the energy transition should be seen as a development opportunity. The construction of large RES plants, especially large solar power plants in Serbia and joining the EU Green Deal, is certainly a signal that Serbia is well on its way to developing a modern, environmentally friendly, competitive and regionally integrated energy system. This will trigger the necessary investments in the modernization of the energy sector and enable the attraction of foreign direct investments. Achieving this vision requires decisive political action at the national and regional levels. Solar projects have the lowest levelized costs of produced kWh of electricity, they are the fastest to implement and they have the least environmental and social impact. Also, large installed capacity can be achieved through a series of large and medium-sized projects that would be territorially distributed in order to reduce the simultaneity of production.

How can we turn an invaded space into a free space? Our project focused on investigating the areas of Loiu (the town where our school is located) where the invasive species of Pampas Grass, Cortadería Selloana, grow. Following the initial investigation we indicated on a paper map where these species can be found. In order to do this, we learned how to use maps, scales, locate our position, and locate the species in the mountains. Later, we investigated how to eradicate them. For this purpose, we studied the previous studies carried out by the University of the Basque Country and the work carried out by the Provincial Council of Bizkaia, eradicating the species in some specific areas of the province. Finally, we presented a dossier in the town hall. Then, the consistory informed the neighbours about how they should deal with this species, and a treatment in public areas has been undertaken. The work of our students promoted a campaign that will benefit our village.

Development of the world economy requires energy supply, which under stable growth must be based on alternative energy resources. Bioenergy is an integral part of energy security supply in volatile countries. It can satisfy a considerable part of energy demand of agribusinesses and other companies as well as facilitate problem-shooting in energy, ecological and social sectors in some regions. Enhancing bioenergy in Ukraine is one of the strategic ways in the development of the alternative energy sector, taking into account high volatility of the country and significant potential of biomass available for energy production. This research intends to determine conditions and mechanisms of development and functioning of bioenergy clusters based on preliminary specification of the bioenergy potential of the territories, taking into account modern marketing approaches. This article contains evaluation of the bioenergy production growth in countries such as China, Germany, France, the USA, Canada, Brazil and Ukraine. The feasibility of the cluster approach for Ukrainian bioenergy development has been proved. In order to combine Ukrainian regions according to all types of energy resources the authors applied the method of clustering analysis. The key point of the method implies that, based on the given set of indicators which are defined as the main characteristics of the object, every object of the population belongs to a similar class. Therefore, in order to study the efficiency of usage of bioenergy resources in a particular region, it is necessary to classify a set of indicators to identify standard forms. To systemize Ukrainian regions, the Isodata algorithm Isodata, based on the types of the economic and energy potential of biomass, is taken into account. To implement the analysis, the following indicators are considered: the biomass energy potential of primary cell waste, the biomass energy potential of trimming, the biomass energy potential of refining, the energy potential of wooden biomass, the mold biomass potential, the energy potential of bioenergy crops, the corn energy potential (biogas). Market players organize groups with regard to their industries, territories and other factors, namely clusters which are likely to become effective tools in while carrying out scale projects under tough competition. In the minor energy sector cooperation between research and manufacturing enterprises, which satisfies energy needs both of cities and individual customers, is growing. This approach perfectly meets all requirements of the regional development of Ukrainian bioenergy. The main goal of bioenergy clusters is to develop competitive advantages of regions by increasing all types of biomass and biofuel production. This implies the following priorities: creation of a database of agribusiness enterprises, which potentially are members of the cluster and corresponding infrastructure, establishment of marketing communications in order to inform members and potential investors about bioenergy advantages, introduction of regional databases by means of webpages, newsletters, public discussions etc., enhanced vocational training of bioenergy industry employees and investment attraction to finance bioenergy projects. As a result, the authors of the paper propose a classification of Ukrainian regions based on the indicators of the economic energy potential of wastes and energy crops in agribusinesses, which is the basis for cluster formation. Vinnytsia, Kyiv, Poltava, Sumy, Khmelnitsky and Chernihiv regions refer to the first type with the biggest bioenergy potential, which makes it possible to create 2 energy clusters by combining central-west and north-east regions. Such a methodology gives an opportunity to satisfy the needs of the regions and districts which need additional energy resources taken from own biomass. Priority tasks of the bioenergy cluster include: development of the database of agribusiness entities which potentially are the cluster members and corresponding infrastructure, informing members and investors about bioenergy benefits, creation of the regional information database identifying the resources, capacity and the transport system, vocational training, investment attraction in order to implement bioenergy projects. Based on clusters, economic relations build up a competitive and sound investment climate to support the economy, which, in turn, provides high living standards. The authors have defined the procedure for exercising the cluster initiative and determined the structure of marketing support for cluster projects.
