To lower the production of greenhouse gases while covering energy needs, it is necessary to exploit renewable energies in the urban environment and manage energy production and consumption as well. In this work, we interested in the study of a house using renewable energy sources such as photovoltaic (PV) panels, thermal panels and wind turbines (WT). The energy consumption happens through electrical charges like the refrigerator, the heat pump, the lighting... The main objective of this work is to change the operating time of secondary loads and to propose an energy management algorithm. Firstly, we will model the consumption of electrical charges and move the operation of secondary charges to moderate the consumed energy. Finally, we suggested an algorithm to manage and optimize energy production and consumption. The results show that the displacement of secondary loads reduces over 8.5% of the energy bill and the suggested algorithm optimizes the operation of the energy production equipment while covering the energy needs of the inhabitants.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.

The article discusses the main problems of the using of biomass as a fuel, including the fuel use of biomass as an innovative way to generate clean energy. It is shown that according to the development of technology for the production of renewable energy sources, energy costs will decrease, and the operating time of the devices and, accordingly, their productivity will increase. Ultimately, this will allow to get a positive result, i.e. reduce harmful emissions from energy production. The methodology basis on the open statistics data and analysis of the energy balance of new energy production technologies are considered. The motivation for the using renewable energy sources in industrialized and developing countries is investigated. A review of new technologies for the using biomass as a fuel is made, which allows for efficient processing of biomass, including gasification, co-production of heat and electricity, fuel use of combustible gases generated at landfills, and production of fuel for transport in the form of methanol and biodiesel.

Renewable energy sources are clean energy sources that meet the energy needs in a sustainable way. Therefore, it is necessary to invest in renewable energy sources. However, there are some difficulties in renewable energy investments. It has problems such as high initial installation cost, underdeveloped technological infrastructure, and insufficient financial support. Several financial products are being developed in order to overcome the mentioned difficulties. In this context, the purpose of this study is to explain the role of green sukuk in the financing of renewable energy investments. Depending on this purpose, the study has been examined with a literature review. The production of renewable energy sources can be encouraged with green sukuk. However, green sukuk is an advantage for Islamic companies that want to realize environmental projects. On the other hand, it offers the opportunity to the environmentally friendly Islamic investors to evaluate their savings.

With the increase in the population in the world and in our country, the energy requirement related to consumer demands is constantly increasing. In our country, although wind, sun, etc. energy sources are used in energy production, fuels of fossil origin (coal, natural gas, oil etc.) are used more in energy production. Renewable energy sources, which are alternative due to the decrease in fossil fuel reserves, negative environmental effects and inability to meet the energy needs in the future, come to the fore. In this study, Turkey Statistical Institute (TUIK) according to the 2015-2019 year data, Sakarya at the central and districts in cultivation areas for cultivated of using the amounts of maize and wheat product (da) average waste, dry matter, and volatile dry matter, methane and energy their potential has been determined. As a result of the calculations, it has been determined that the maize sap waste amount has the highest 25695.68 tons of waste and 201197.15 MJ energy potential in Adapazarı district in 2017. Among the wheat stalk wastes, in 2017, Geyve district had the highest 269.95 tons of waste and 2113.72 MJ energy respectively.

In addition to the examination of electric power from local renewables, this study has sought the answer to the question of what proportion of vehicles are fueled by environmentally friendly energy saving technologies in the vehicle fleets of Hungarian settlements. Further, the study attempts to shed light on the self-sufficiency of Hungarian settlements with respect to the electricity and transport segments. In our assessments, the performance of small-scale household power plants (SSHPPs) utilizing local renewable energy sources, and small-scale power plants with installed capacities under 0.5 MW, was taken into account, as were the proportions of vehicles operating with partly or completely clean energy sources in the vehicle fleets of the individual settlements. Finally, the composition of the vehicle fleet has been examined in the light of the quantities of renewable electricity generated in the individual settlements, in order to consider whether these settlements are capable of covering the energy needs of their vehicle stocks from local sources. In the light of the results, the changes generated by the incentives and investments introduced over the past ten years can be established and subsequently, the energy policy needs in the future can be assessed. Our study has incorporated energy geography and settlement geography aspects.

Utilization of alternative sources named as new and renewable energy sources; Due to technological development and difficulties in competing economically with traditional resources, it has not reached the desired level until today. Due to the rapid increase in energy consumption today; It is a fact proved by scientific findings that fossil fuels will be consumed in the near future. Therefore, in the development of countries; Providing timely, reliable, clean and uninterrupted energy, creating a market environment, in other words, successful implementation of energy management have become imperative. Energy has become one of the most important problems of the world countries today. As is known, the lifetimes of energy sources such as coal and oil are limited. In addition, due to the use of fossil fuels; It is a fact that global warming is increasing day by day. In the light of the data obtained, for our energy needs; alternative solutions should be found, renewable energy sources should be evaluated. The importance of renewable energy sources has increased as the problems related to environmental pollution increase, and projects related to them have started to get support. These energy sources can basically be classified as hydroelectric energy, wind energy, solar energy, geothermal energy, modern biomass energy and hydrogen energy. Economic and efficient operation of new and renewable energy sources should be transformed into a common understanding in order to provide clean energy.
