Energy savings among households is an important energy challenge in Japan. After the Great East Japan Earthquake in March 2011, electricity shortages became a worry because nuclear power plants ceased operations. The conditions that households require to save electricity are analyzed in the paper by a conjoint analysis. An annual electricity bill, CO2 emissions, a stable electricity supply, and energy sources that generate electricity are considered. The role of energy sources, especially renewable energy, in energy savings is focused. When renewable energy such as solar and wind power is used, households who prefer it might use less electricity as well. A random parameter logit model is used for estimation. The promotion of renewable energy and energy savings should be encouraged in Japan’s official energy policy. If electricity generated by renewable energy is provided, households that prefer renewable energy choose such an electricity and will reduce their electricity usage. As a result, the promotion of renewable energy and energy savings could be addressed simultaneously. The estimation results indicated that households would save more electricity if an annual electricity bill is reduced. In addition, they also would save more electricity if CO2 emissions are reduced and if a stable electricity supply is secured. If nuclear power is used for electricity generation, they do not use less electricity. If renewable energy is provided, they tend to use less electricity. Thus, renewable energy provides incentives for households to reduce electricity usage. It is possible to promote energy savings by utilizing consumers’ interest in renewable energy.

Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

Energy Independence

The paper defines the directions of improving turbogenerators as the basis for ensuring the energy independence of Ukraine. The analysis of the state, problems and prospects for the development of modern electric power industry. Goal of the work is to identify promising directions for sustainable development of the national electric power industry in order to ensure energy security of Ukraine, to conduct a comparative analysis of electricity sources, to confirm the need to improve the main sources – turbogenerators. Methodology. During the research, an analytical analysis of the electricity sources, which are installed at power plants in Ukraine and the world, was carried out, taking into account the growth of the planet's population and its energy activity. Cyclic theory was chosen as the theoretical basis for forecasting. On the basis of this theory, global development trends, advantages and disadvantages of currently used sources of electricity - thermal (including nuclear) power plants and stations that operate from renewable energy sources - have been established. A review of literary sources on the methods of the energy sector forecasting the development, including the development of the energy sector in Ukraine, has been carried out. Originality. It has been established that due to the active growth of the planet's population, with the increase in its energy activity, obtaining electricity from renewable energy sources is not enough, that for the next 20-30 years nuclear power plants will be the main sources of electricity. The internal and external threats to the energy security of Ukraine, directions of development of turbogenerator construction, ways to improve turbogenerators, to increase their energy efficiency, power per unit of performance, to increase the readiness and maneuverability factors, and overload capacity have been identified. Practical significance. The need to continue the modernization and improvement of the turbogenerators of nuclear power plant units, as the main sources of electricity, has been proved. The directions of their improvement are established: increasing the power in the established sizes, making changes to the design of the turbogenerators inactive elements, replacing the cooling agent to keep Ukrainian turbogenerators at the world level, improving auxiliary systems, improving and increasing the reliability of the excitation system, introduction of automatic systems for monitoring the state turbogenerators. Possible limits of use, advantages, disadvantages and problems of using renewable energy sources for Ukraine have been established.

Level Of Education

Our paper studies the link between the education and the people’s opinions and views of the renewable energy sources (RES). We employ the representative data (1026 respondents) from the Czech Republic. Our empirical model did not reveal any associations between the subjective opinion on the respondents about the possibility to replace electricity generation from conventional sources (such as coal-fired or gas-fired power plants, nuclear power plants or large hydroelectric power plants) with the electricity from wind, solar radiation and biomass combustion. In addition, there seemed to be no correlation between the usage of renewable energy in the Czech Republic and the education of the respondents. However, there are strong significant association between the level of education of the respondents and the existence of opinions on the RES. Higher education means higher probability of the existence of such an opinion. Almost one third of the respondents with primary education did not have an opinion on the topic. This might be caused by an increasing interest in RES of people with higher level of education as they are likely to be more open to all discussions on the socially relevant issues in general. The lack of association between which opinion people have and their level of education is likely to indicate the marginal role of explaining the importance of RES in education.

Bipolar Scale

This paper focuses on the analysis of trends in the development of nuclear energy in selected European and non-European countries in the context of the pace of renewable energy development in the world. The perception of Poles related to their openness to various energy sources against the background of European trends was also examined, as well as their ecological approach to the quality of the environment in this context. The survey was carried out using the Computer Assisted Web Interview (CAWI) technique. The total number of correctly completed forms was 923. To identify the ecological attitude, purchasing attitude, and the perception of nuclear energy, the research tool contained a number of statements on the issues studied, and the respondents assessed compliance with their opinion using a seven-point bipolar scale. The semantic differential was also used to gather opinions on the characteristics of nuclear energy. This paper shows that global trends are promoting the development of unstable renewable energy sources and the reduction of the share of nuclear power plants as an energy source. It has also been shown that the Organization for Economic Co-operation and Development (OECD) countries are more skeptical about nuclear power than countries that do not belong to the OECD (for example, China and Africa).

The Cost

The statistical analysis of the forecast error of the "day ahead" electricity supply volumes by the producers, which are included in the balancing group of the State Enterprise "Guaranteed Buyer”, was carried out. The distribution of forecast errors by hours of the day is determined. A simplified method for calculating the price and the total cost of the forecast error is described considering the various formulas for the cost of imbalances calculating. The potential for improving the accuracy of the forecast for increasing the permissible installed capacity of power plants with renewable energy sources with the technical means available in the power system to compensate for the power fluctuations is shown. Approbation of the methodology and calculation of quantitative indicators was carried out on real data of the total supply of renewable energy sources by producers, which were published by SE Energorynok. The calculations are of an estimate nature. Since the calculations are based on a “naive” assumption about the distribution of forecast errors, which depend on the structure of RES producers by types of primary energy carriers and specific meteorological conditions.
