As a result of rapid financial development and natural disasters, energy efficiency research, and high-quality electricity alternative energy options, as well as efficient electricity sources. In particular, the use of green energy sources has become a hot issue; As a result, distributed electricity supply in the micro grid is the basis for the achievement of the vital objectives of successfully providing the customer with currency and stability. The article proposes a hybrid metaheuristic approach based on the Eagle strategy Technique (ES) and Particular Swarm Optimizing (PSO) Technology, which will minimize low-voltage running costs from a renewable energy source such as an electricity generator, solar panels, wind generators, micro turbines and fuel cells. The cost optimization problem is set up as a nonlinearly constrained problem. In order to maximize distributed generation, a mathematical problem must be solved. The proposed hybrid solution is evaluated on low-voltage micro grids, and its optimal performance is compared to that of other hybrid approaches and variety of other metaheuristic techniques

The need for a sustainable green energy is increasing, while the availability of energy itself is not comparable to the needs. One of the most rapid activities in human life is footstepping. The large amounts of kinetic energy in term of pressure force are generated in every footstep activities at the crosswalk space, lecture building, office, shopping centre or market area. As an alternative energy that still has not been exploited, these human steps can be used to power some low voltage loads. In this study, a tile constructed with some piezoelectric transducers are designed and implemented to generate electrical pulses and harvesting human feet step energies. The piezoelectric transducers used in this study is Lead Zirconate Titanate type. From the pizoelectric floor energy harvester system, a tile consists of 20 pieces parallel connected piezoelectric transducer can produce AC voltage up to 71.20 V. While the average generated voltage is 63.98 V. So the average power is 0.0604 watt/10 footsteps. We conclude that this piezoelectric generator can be generated more power when arranged with some tiles arrangement, so we can harvest this energy efficiently.

Alternative Sources

As demand for electricity grows significantly, the main drivers of new capacity are the disposal of older, less efficient fossil fuel units; the near-term prospect of having tax credits for renewable energy; and long-term reductions in capital costs for renewable energy, especially solar photovoltaic. Low natural gas prices and favorable renewable energy costs make natural gas and renewable energy the main sources of new generation capacity by 2050. The main purpose of the scientific article is to cover the main problems of the electricity market of Ukraine, to analyze the process of promotion of green energy, to highlight the cases when the transition to alternative sources is a profitable process, in the context of uncertainty and rising prices for traditional energy sources. The article uses a number of general scientific and specific research methods, including methods of analysis and synthesis, scientific deduction and induction. The practical significance of the research is to develop recommendations for improving the state's regulatory function in the field of alternative energy. The large-scale introduction of non-traditional renewable energy in Ukraine will make a significant step in reducing the country's energy dependency, protecting the environment and creating the conditions for a country to join the European community. The scientific novelty is to study the stimulation of energy production using alternative sources, to study the creation of favorable economic conditions for the construction of alternative energy facilities, the development of a "green" economy and to ensure sustainable development of Ukraine. Conclusions and prospects for further research. In Ukraine, the alternative energy sector is developing slowly, but some structural shifts are noticeable, though far from planned. Many small and medium-sized enterprises have already installed solar panels in order to reduce the cost of production and generate additional profits. Further research requires the search for tools and mechanisms in the RES incentive system, with an assessment of the economic impact of their use, using modeling and forecasting methods and models.

Green Investments

Large, one-time investments in green energy installations effectively reduce domestic energy use and greenhouse gas emissions. Despite long-term economic benefits for households, the rate of green investments often remains moderate unless supported by financial subsidies. Beyond financial considerations, green investments may also be driven by individual psychological factors. The current study uses data from the German Socio-Economic Panel (N = 3,468) to analyse whether the household decision to invest in green energy installations is linked to the Big Five personality traits. Personality traits and domestic investments in solar and other alternative energy systems had weak indirect associations through environmental concern but not through risk preferences. Openness to Experience and Neuroticism showed a weak positive relationship with green energy installations through the environmental concern channel, whereas Extraversion had a weak negative link. Based on these findings, persuasive messaging for green investments may be more effective when it focuses on environmental concern rather than reduced risk in countries like Germany, where long-standing financial subsidies decreased the risk in green investments.

Biogas Technology

The increased availability of reliable and efficient energy services stimulates new development alternatives. This article discusses the potential for such integrated systems in the stationary and portable power market in response to the critical need for cleaner energy technology. Several issues relating to renewable energies, environment, and sustainable development are examined from both current and future perspectives throughout the theme. It is concluded that green energies like wind, solar, ground source heat pumps, and biomass must be promoted, implemented, and demonstrated from the economic and/or environmental point of view. Biogas from biomass appears to have potential as an alternative energy source, potentially rich in biomass resources. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biogas technology. Finally, this article gives an overview of the present and future use of biomass as an industrial feedstock to produce fuels, chemicals and other materials. However, to be truly competitive in an open market situation, higher-value products are required. Results suggest that biogas technology must be encouraged, promoted, invested, implemented, and demonstrated, especially in remote rural areas. Anticipated future energy use patterns and consequent environmental impacts (acid precipitation, ozone depletion, greenhouse effect, or global warming) are discussed in this article. An approach is needed to integrate renewable energies in a way to meet high building performance. However, their ability to match demand is determined by adoption of one of the following two approaches: the utilisation of a capture area greater than that occupied by the community to be supplied, or the reduction of the community’s energy demands to a level commensurate with the locally available renewable resources. Adopting green or sustainable approaches to how society is run is seen as an important strategy in finding a solution to the energy problem. The key factors to reducing and controlling CO2, which is the major contributor to global warming, are the use of alternative approaches to energy generation and the exploration of how these alternatives are used today and may be used in the future as green energy sources.
