Developing Area

Renewable energy is a rapidly developing area of the modern economy. As many experts forecast, global electricity consumption will double by 2050, while the share of renewable sources in energy generation will be 50%. For most states, the main incentives for the development of renewable energy are the ability to eliminate the consumption of fossil fuels and reduce the level of emissions of pollutants, while ensuring sustainable development of the country. At the same time, Russia, which has significant reserves of natural resources, is in no hurry to switch to the use of energy from renewable sources since it is believed that the country’s subsoil can provide it with cheap energy resources for many generations to come. Therefore, introduction of renewable energy sources that are unable to compete with traditional energy without a developed energy infrastructure and established production is impractical. In our study we try to evaluate the efficiency of the introduction of renewable energy sources in the Krasnoyarsk Territory of Russia using the example of the Chinese experience.

Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.

As the Egyptian population is increasing at a huge rate, the yearly housing demand is increasing in an equivalent rate. In addition, the whole world is suffering from an energy crises caused by the rapidly increasing consumption of world’s traditional energy resources, so the obvious solution is to go green, and depend much more on renewable energy resources. According to the statistical data available in Egyptian governmental authorities, the accumulated housing demand till 2014 was about 2,400,000 units. On the other hand, the yearly housing supply from private and public sectors is about 150,000 to 200,000 unit, Egyptian authorities declared that at summer 2010 air-conditioning devices increased to reach 3.000.000 ( three million) devices all over Egypt, mostly working from early mornings till 2 am next day to adjust temperatures that reach up to (45C) and more outside buildings to reach (25 C) or less inside. This behavior increased electricity consumption rapidly. Consequently, the electricity consumption rate in Egypt had increased by 13% more than 2009, which exceeds the maximum capacity power of the high dam by 7% to 8%, ministry of electricity announcements declared that to fill that gab we need 3000 megawatts at peak hours which costs the electricity sector up to 16.000.000.000 l.E. Accordingly, a new architectural design concept is proposed (Zero-Energy Housing Unit) to rely on the surrounding environmental conditions and new Green Architecture Techniques in order to provide human comfort based on renewable energy sources, provided that the common current governmental energy sources will be a backup system for the meanwhile.

Electricity Infrastructure

The electricity grid in the United States may be the largest, most pervasive technological system ever constructed to meet the needs and comforts of human beings (Nye 1997). Although it is less than 150 years old, the electricity infrastructure of this nation is ubiquitous; power lines stretch across deserts, forests, states, highways, and the entire nation in order to provide electricity to residences, businesses, and communities. The electricity carried by these transmission lines is generally produced using fossil fuels (mostly coal; see US Energy Information Administration 2012) and is most commonly generated at a monstrously large facility (a coal plant, a nuclear facility, or a hydropower dam). Our electricity infrastructure was constructed to carry enormous amounts of electricity across vast geographical expanses, based on the massive generation facilities and concentrated fossil fuel based energy sources that defined the system and its use. However, there are increasing concerns regarding the sources of our energy supply. Many of these concerns are related to climate change and how carbon dioxide emissions from burning fossil fuels contribute to rising global temperatures and the climate instability of the planet (Brown 2003). Additional concerns include the host of other environmental damages caused by the use of coal (Epstein et al. 2011), nuclear energy (Slovic et al. 1991), and hydro-electricity (Dincer 1998); other debates involve worries about nearing or reaching peak energy supplies (Brown 2003), energy security (Yergin 2006), and the aging transmission grid (Amin 2003). For a multitude of reasons, many would agree that it’s time to rethink our dependence on fossil fuel based forms of energy and move toward alternative, renewable energy sources (Brown 2003, pp. 116–135). The good news is, the renewable energy industry gets bigger every year, with more energy from renewable sources being produced, sold, and used (Sherwood 2011). Some US states have enacted renewable energy standards requiring that a certain percentage of their electricity supply come from renewable sources. Tax incentives, subsidies, and various forms of rebates, in financially incentivizing renewable energy adoption, also provide evidence that we are indeed moving in the direction of clean, renewable sources of energy.

With the industrialization of the world, energy resources need management more than anything else. Because today we live in an energy-dependent world, we need energy to generate heat and cold, to create light, to start car engines, to run factory gears, to harvest crops, and so on. Therefore, the present study aimed to investigate the need for efficiency of energy sources management in sustainable architecture was conducted. In this research, a descriptive-analytical method has been used to look at the concept of energy resources management and sustainable development and their relationship, to study renewable energy sources in Iran and to propose proposed solutions in this regard. The results show that energy management requires the presentation of policies by managers of a country and also requires public education at the community level. Achieving sustainable development also requires access to sustainable energy sources that non-renewable energy and fossil fuels are not suitable sources in this regard due to unsustainability, but renewable energy will remain for future generations if used, unlike fossil fuels. They will not lead to pollution and global warming. Undoubtedly, by replacing renewable energies with non-renewable energies, the steps taken towards sustainable development will become stronger. In addition to these issues, the epidemic and the increase in the number of victims and victims of the Covid-19 virus, which led to the closure of oil fields, refineries, mines, etc., was another blow to the managers and officials of countries to find out more than ever the only solution to these problems is referring to renewable energy.

In the last few years, the world has been turning to the exploitation of renewable energy sources due to increased awareness of environmental protection and increased consumption of fossil fuels. In this research, by applying geographic information systems and integrating them with multi-criteria decision making methods, an area suitable for the construction and exploitation of renewable energy sources is determined. The research uses not only climate, spatial, environmental, and geomorphological parameters but also socioeconomic parameters, population, unemployment, and number of tourist nights as well as electricity consumption. By applying spatial analysis, rasters of all parameters were created using GRASS GIS software. Using the analytic hierarchy process, the calculated rasters are assigned with weight coefficients, and the sum of all those rasters gives the final raster of optimal locations for the construction of solar power plants in Croatia. To test the accuracy of the obtained results, sensitivity analysis was performed using different weight coefficients of the parameters. From the sensitivity analysis results, as well as a histogram and statistical indicators of the three rasters, it is apparent that raster F1 gives the best results. The most decisive parameters in determining the optimal solar plant locations that result from this research are GHI, land cover, and distance to the electricity network.

Renewable energy is considered an infinite source of energy. Although they have unlimited potential towards making our environment self-sustainable, they are currently insufficiently exploited and unevenly distributed. The major hindrance to exploiting these renewable sources is economic issues. Some countries, that possess these sources are currently developing or are still in the under-developed scenario. Hence, these resources are not being exploited to their full potential. We are aware of the severe consequences of burning up fossil fuels and their adverse effect on our environment Rarely do we think of the consequences on the environment due to renewable energy sources. Although they have a very small impact on our environment, in the future it might lead to some devastating issues. Some of the renewable energy sources have a visual impact on the nature of our earth and also to some extent it can affect the ecosystem of a particular area. This paper intends to analyze the current types of renewable sources (solar, wind, geothermal and hydroelectric) and their impact on our planet.

Global Power

National and international energy policies have very important role in regional and global power equilibrium and its importance is increasing. In this respect, diversification of energy resources and their transportations routes, efficient use of local resources and the use of existing energy resources with various technological and strategic practices in the most efficient way possible are necessary in order to improve energy security and reduce dependence on foreign energy sources. Energy efficiency and renewable energy sources stand out as an important issues especially regarding energy supply security, reducing foreign energy dependency, economic development, maintaining the balance between environment and sustainability as well as making important gains in all these issues. Thus, Improving energy efficiency saves money, reduces carbon emissions and decreases country’s dependence on foreign energy supplies. Energy security—the uninterrupted availability of energy sources at an affordable price—can also profit from improved energy efficiency by decreasing the reliance on imported fossil fuels. Possible improvements in energy efficiency are examined in six main categories: (1) buildings, (2) industry, (3) transportation, (4) electricity generation and distribution, (5) appliances and equipment, and (6) lighting
