In The Beginning

Energy transition from a carbon energy driven world to a decarbonized world (H2) is essential for the living for our next generations. Our existing energy source with contents in the beginning (1850) nearly only the element C are used with all their consequences for the burning process and environmental impact. Nowadays the C element in our present energy sources are getting less and less. The environmental impact using fossil energy is huge and with the climate change more and more deadly for the inhabitants on the earth. Producing H2 as a sustainable and renewable energy is only possible using renewable energy sources like PV, Wind, Hydro, Biomass. With today's technology and the constant falling energy prices since the last 20 years H2 is now an alternative secondary energy source for a substitute for fossil sources. Using H2 will give new and unique business advantages. With these business advantages, new and innovative business models can be designed and developed. These novel approaches can be very sensitive to external influences. This destructives situations are making these BM very fragile. Finding ways to stabilize these on a long term without aid from the outside the key for success are new innovative technologies and new innovative BM.

Energy Justice

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

In this study we aimed to determine the extent to which changes in the share of renewable energy sources, their structural complex, and the level of energy security in Eastern Europe, Caucasus and Central Asia (EECCA) countries in the medium- and long-term are interconnected. The study was performed through modeling and determination of the structural characteristics of energy security in the countries. The methodology of the approach to modeling was based on solving the problem of nonlinear optimization by selecting a certain scenario. For the study, the data of EECCA countries were used. The ability of EECCA countries to benefit from long-term indirect and induced advantages of the transformation period depends on the extent to which their domestic supply chains facilitate the deployment of energy transformation and induced economic activity. This study provides an opportunity to assess the degree of influence of renewable energy sources on the level of energy security of countries in the context of energy resource diversification. The high degree of influence of renewable energy sources on energy security in the EECCA countries has been proven in the implementation of the developed scenarios for its increase. Energy security is growing. At the same time, its level depends not only on an increase in the share of renewable sources but also on the structure of energy resources complex of countries, and the development of various renewable energy sources. Therefore, today the EECCA countries are forced not only to increase the share of renewable energy sources but also to attach strategic importance to the structural content of their energy complex.

Near Future

Many leading world powers are already setting ambitious goals to achieve zero CO2 emis-sions in the electric power industry through the use of renewable energy sources (RES) in the near future. In Russia, this type of generation also received state support, however, more modest, due to the low intercon-nection between Russia and renewable energy sources in terms of the state's energy security. The purpose of the study is to determine the effectiveness of the existing support for renewable energy in the Russian Federation, to assess the feasibility of building these facilities in our country, as well as to provide a scientifically substantiated proposal for alternative ways of developing the industry. The paper analyzes and summarizes the economic aspects of investment and operating activities of wind, solar and small hydropower in Russia. As a result, it was concluded that the pace of development chosen by the Ministry of Energy of the Russian Federation can be considered correct, but it is necessary to adjust the support program and diversify in terms of the subjectivity of the construction of new generating facilities based on RES.

The Impact

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.

Support Functions

The gradual displacement of synchronous generators driven by conventional power plants, due to the increasing penetration of distributed renewable energy sources (DRES) in distribution grids, is creating a shortage of crucial ancillary services (AS) which are vital for the frequency and voltage stability of the grid. These AS, and some new ones, could now be offered by the DRES, particularly those that are converter interfaced, in a coordinated way in order to preserve the grid stability and resilience. Although recent standards and grid codes specify that the DRES exhibit some system support functions, there are no specifications on how to measure and quantify (M & Q) them both at DRES level and in aggregated form. The M & Q of AS is crucial, since it would allow the AS to be treated as tradable AS in the current and future AS markets. This paper attempts to define a number of AS that can be offered by converter-interfaced DRES and suggests methods for their M & Q. The new AS addressed are: (1) inertial response; (2) primary frequency response; (3) active power smoothing (ramp-rate limitation); (4) exchange of reactive power for voltage regulation; (5) fault-ride-through (FRT) and contribution to fault clearing; (6) voltage harmonic mitigation. Additionally, a rough estimation of the additional investment and operational cost, as well as the financial benefits associated with each AS is provided in order to form the basis for the development of business models around each AS in the near future.

Savonius Wind Turbine

Our planet gives us many mineral sources, but they have a big disadvantage. They are finite. Non-renewable energy sources are enough only for decades, exceptionally for centuries. Current generation is aware of the importance of using other energy sources, such as sunlight, wind, rain, tides, waves and geothermal heat. These energy sources are renewable. It means that they come from sources, which are naturally replenished on a human timescale. One of these sources is wind energy. Use of this kind of energy source needs an initial investment, but it can reduce cost of running a household and other sectors. This article is about Savonius wind turbine and its use for the needs of public lighting.
