Hydropower as a renewable energy source is a serious future alternative to organic fuel power and environmental protection. Its use is least damaging to the environment in comparison to thermal and nuclear power. Hydropower is a constant generating source and a type of energy that yields most return. Based on this approach, the article assesses the hydropower development, reveals the reasons behind the hindrance of renewable energy source development, evaluates the tendencies and development prospects, draws the conclusions and presents the recommendations. This article reflects the concept of the latest findings of scientific research and practical interface. Planning, design, construction and operation of hydropower facilities, must be determined on how they may affect the natural state of water bodies, it is imperative to analyze and assess the environmental protection effectiveness. Natural water bodies should not be modified without an environmental impact assessment

Diesel acts as a main energy source to complement human activities in Antarctica. However, the increased expedition in Antarctica has threatened the environment as well as its living organisms. While more efforts on the use of renewable energy are being done, most activities in Antarctica still depend heavily on the use of diesel. Diesel contaminants in their natural state are known to be persistent, complex and toxic. The low temperature in Antarctica worsens these issues, making pollutants more significantly toxic to their environment and indigenous organisms. A bibliometric analysis had demonstrated a gradual increase in the number of studies on the microbial hydrocarbon remediation in Antarctica over the year. It was also found that these studies were dominated by those that used bacteria as remediating agents, whereas very little focus was given on fungi and microalgae. This review presents a summary of the collective and past understanding to the current findings of Antarctic microbial enzymatic degradation of hydrocarbons as well as its genotypic adaptation to the extreme low temperature.

Biomass is organic material, the second most important source of energy. Biomass is a renewable energy source. Wood biomass is used as source of energy for heating in many regions in Slovakia. It is because of its availability. Wood biomass is an easily accessible and affordable source of energy. At present, thermochemical processes, biochemical processes and physical-chemical processes are used for biomass utilization. In the article a suitable technology for combustion of wood chips is proposed. It consists of five main technological parts: transport of wood chips, silo, combustion boiler, and stack.
