The Impact

Currently, a lot of focus is dedicated to metal hydride alloy and options of their utilization. Mankind must solve energy problems due to constant population growth and use of non-renewable energy sources. The World resources of oil are limited and therefore the mankind must start utilizing the alternative energy sources for example hydrogen. Its known that the hydrogen can be stored by metal hydride alloys what it represents the safety way of storage with absence high pressure and temperature. The process by produce of the alloy with good absorption properties the research does not end. Some alloy absorbs the hydrogen after they produce immediately, however a lot of them need the activation for improvement or starting absorption process. Process of activation is very important for achieving the maximum capacity at moderate temperature.

The Impact

The increasing needs of people who are not balanced with fuel supplies at the national and world level are bringing about the impact of the energy crisis. The reliance only on renewable energy makes people have to look for alternative energy sources. Bioethanol is a type of fuel that can replace fuel. The bioethanol process is fermented from biomass material with the help of microorganisms. This study aims to know the performance of yeast composition in the fermentation process against ethanol quality. The ingredients used are molasses with a sugar content of 54% as much as 8 L. Molasses is mixed with NPK, Urea, and the yeast Saccharomyces Cerevisiae. Khamir's composition varies by 8, 12, 16, 20, 24, 28, and 32 grams. To test ethanol levels on each variable by measuring the difference in water density and ethanol using a pycnometer. This study's result is the highest ethanol quality obtained at a sugar concentration of 12 grams (0.2%), at 5.6%. The lowest ethanol quality is obtained at a sugar concentration of 32 grams (0.4%) i.e., 3.29%, while in yeast composition 8, 16, 20, 24, 28 grams of ethanol quality continued to decrease consecutively to 3.6%, 5.4%, 5.3%, 5.2%, and 5.1%.

The Impact

The energy crisis of 1973-1974 showed that it is difficult to constantly increase the power supply of production, based only on traditional energy sources. The power supply of society is the basis of its scientific and technological progress. It means that it is necessary to introduce unconventional, alternative energy sources more widely. Unlike fossil fuels, unconventional forms of energy are not limited to geologically reserves. Their use and consumption does not lead to the inevitable exhaustion of stocks. However, currently, the reform of world energy markets and increasing the share of renewable energy sources in their structure is a long and innovative process. Lots of countries (Russia in particular) bear significant risks because of reforming their own energy market, which causes a slight increase in the share of renewable energy sources. In this regard, the purpose of this study is to analyse the influence of environmental factors on the development of renewable energy sources in Russia. The result of this study is a system of econometric equations, which allows to evaluate the impact of changes in key drivers of the development of the renewable energy market.

Development Prospects

This paper identifies the structure of the energy balance in the world and in individual countries was analyzed, trends and factors in the development of alternative types of energy carriers. The impact of their development on the volume and structure of international energy trade is substantiated. Its development prospects are presented for developed countries that are leaders in the development of alternative energy sources, and for developing countries for which the price factor is more important. Prospects of development of Russian energy exports in conditions of increasing importance of alternative types of energy carriers in the world economy and international trade are considered.

Abstract The maritime environment protection is increasingly reflected in legal regulations regarding, inter alia, the harmful exhaust gas components emitted by marine combustion engines. The provisions imposing the emission limits for SOx, NOx and CO2 are included in MARPOL 73/78 ANNEX VI adopted by the International Maritime Organization (IMO). However, as of today, these provisions are not applicable to fishing cutters. One of the methods, both to decrease emissions’ volume and also to reduce the operating costs of ships, is to lower fuel consumption of marine energetic systems. The paper presents a proposition of energy-efficient and environmentally friendly energetic systems for coastal fishing cutters. It also demonstrates the importance of the said systems and includes the elaboration regarding the impact of fuel type, renewable energy sources and energy conversion methods on the hazards to the environment caused by the emission of harmful exhaust gas components. The presented solutions refer to fishing cutters of the length of 15-30 m and are categorized into two groups. The division criterion applied is an access to technologies currently available and future technologies enabling the use of alternative energy sources.

One way to prevented and breaked the chain of spreaded the Covid-19 virus is to handle it. By diligently used soap for at least 20 seconds, it can prevened transmission of the Covid 19 virus. Because hands are the part that is often exposed to direct interaction. So that bacteria and viruses can easily stick to the hands. Therefore an innovation is needed to make a touchless automatic sink that will touch the touch of the hand both when taked soap, washed hands with air and then dryed hands with a hand dryer so that they touch the touch with objects. This automatic sink was innovated using Solar Cell as an alternative energy to electric power. The solar cell used is 30 WP. This tool uses an IR Infrared Obstacle Avoidance sensor as input. Water pump, soap pump, hand dryer will each operate a sensor which has a hitch. The test results show the sensor can detected an obstacle 2-10cm away. The energy produced by the solar cell based on the test results obtained at 50-100% power, the tool can function properly, but at battery power below 50% indicates a decrease in function, namely the hand dryer cannot function.
