There is a growing need for sustainable forms of renewable energy sources that are efficient, and cost-beneficial. Finding such energy sources is one of the critical challenges of the 21st century. This paper focuses on the prospects of using high energy particles abundant in the universe as a solution to the energy crisis faced around the world. The high energy particle studied in this paper is the neutrino. Neutrinos are subatomic particles that are one-millionth the size of an electron (“How much does a neutrino weigh”, n.d). They are of interest to physicists because they are present virtually everywhere, travel through regular forms of matter, and have exceptionally high energy levels (“What is a Neutrino”, 1999). Neutrinos have ten billion electron volts when traveling freely across space, which is enough energy to break up the nucleus of an atom (“Neutrino Energies”, n.d). Due to their high energy levels and eternal presence, neutrinos are a promising candidate for a renewable energy source. However, due to minimal reactions with other forms of matter, it is difficult to harness their intrinsic energies. A panel that is capable of absorbing neutrinos can potentially produce substantial amounts of heat energy, which can then be converted into electricity.  Energy from neutrinos is a great theoretical alternative and a clean source of energy for our planet and future generations to come. This paper takes another step forward in the mission to produce a primary source of energy that is green and sustainable for our planet.

Retrofitting “nearly-zero energy” heritage buildings has always been controversial, due to the usual association of the “nearly-zero energy” target with high energy performance and the utilization of renewable energy sources in highly regarded cultural values of heritage buildings. This paper aims to evaluate the potential of turning heritage building stock into a “nearly-zero energy” in hot, dry climates, which has been addressed in only a few studies. Therefore, a four-phase integrated energy retrofitting methodology was proposed and applied to a sample of heritage residential building stock in Egypt along with microscale analysis on buildings. Three reference buildings were selected, representing the most dominant building typologies. The study combines field measurements and observations with energy simulations. In addition, simulation models were created and calibrated based on monitored data in the reference buildings. The results show that the application of hybrid passive and active non-energy generating scenarios significantly impacts energy use in the reference buildings, e.g., where 66.4% of annual electricity use can be saved. Moreover, the application of solar energy sources approximately covers the energy demand in the reference buildings, e.g., where an annual self-consumption of electricity up to 78% and surplus electricity up to 20.4% can be achieved by using photo-voltaic modules. Furthermore, annual natural gas of up to 66.8% can be saved by using two unglazed solar collectors. Lastly, achieving “nearly-zero energy” was possible for the presented case study area. The originality of this work lies in developing and applying an informed retrofitting (nearly-zero energy) guide to be used as a benchmark energy model for buildings that belong to an important historical era. The findings contribute to fill a gap in existing studies of integrating renewable energy sources to achieve “nearly-zero energy” in heritage buildings in hot climates.

Power is a significant cause of economic growth and crucial to the sustainability of the economy. Energy consumption is an indicator of a nation's economic growth. Economic growth is focused, among other aspects, on the long-term acquisition of affordable, existing resources, and their use does not pollute the environment. Industrialization serves economic growth and consumes energy. In 2018, 68% of total capital power was consumed by largest energy-intensive areas. When fossil fuel is the primary source of energy, energy consumption is positively correlated with ecosystem cleanliness. Fossil fuels account for more than 70% of the decent energy expectations of India and other economies. In this chapter, problems related to non-renewable energy sources are discussed, and emphasis is given to use more renewable sources.

AbstractPopulation increase and industrialization has resulted in high energy demand and consumptions, and presently, fossil fuels are the major source of staple energy, supplying 80% of the entire consumption. This has contributed immensely to the greenhouse gas emission and leading to global warming, and as a result of this, there is a tremendous urgency to investigate and improve fresh and renewable energy sources worldwide. One of such renewable energy sources is biogas that is generated by anaerobic fermentation that uses different wastes such as agricultural residues, animal manure, and other organic wastes. During anaerobic digestion, hydrolysis of substrates is regarded as the most crucial stage in the process of biogas generation. However, this process is not always efficient because of the domineering stableness of substrates to enzymatic or bacteria assaults, but substrates’ pretreatment before biogas production will enhance biogas production. The principal objective of pretreatments is to ease the accessibility of the enzymes to the lignin, cellulose, and hemicellulose which leads to degradation of the substrates. Hence, the use of pretreatment for catalysis of lignocellulose substrates is beneficial for the production of cost-efficient and eco-friendly process. In this review, we discussed different pretreatment technologies of hydrolysis and their restrictions. The review has shown that different pretreatments have varying effects on lignin, cellulose, and hemicellulose degradation and biogas yield of different substrate and the choice of pretreatment technique will devolve on the intending final products of the process.

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.

Waste Leachate

It has become urgent to develop cost-effective and clean technologies for the rapid and efficient treatment of food waste leachate, caused by the rapid accumulation of food waste volume. Moreover, to face the energy crisis, and to avoid dependence on non-renewable energy sources, the investigation of new sustainable and renewable energy sources from organic waste to energy conversion is an attractive option. Green energy biohydrogen production from food waste leachate, using a microbial pathway, is one of the most efficient technologies, due to its eco-friendly nature and high energy yield. Therefore, the present study aimed to evaluate the ability of an enriched bacterial mixture, isolated from forest soil, to enhance hydrogen production from food waste leachate using biochar. A lab-scale analysis was conducted at 35 °C and at different pH values (4, no adjustment, 6, 6.5, 7, and 7.5) over a period of 15 days. The sample with the enriched bacterial mixture supplemented with an optimum of 10 g/L of biochar showed the highest performance, with a maximum hydrogen yield of 1620 mL/day on day three. The total solid and volatile solid removal rates were 78.5% and 75% after 15 days, respectively. Acetic and butyrate acids were the dominant volatile fatty acids produced during the process, as favorable metabolic pathways for accelerating hydrogen production.

At present, the energy from renewable sources is an important element of the sustainable development strategy of the European Union (strategy covering the period until 2020). The article presents the role of renewable energy in the structure of primary energy sources and total energy production. In order to evaluate the present-day role of the renewable energy sector, specific European Union states were analysed, with particular focus on Poland, the country whose results were juxtaposed with the average ratios established for the EU-28. A detailed analysis of the current facts was performed (also a forecast for the period running up to 2020 was made), where particular energy sources were distinguished in the renewable energy production structure. A special role among renewable energy sources was ascribed to solar energy, wind energy, hydropower, geothermal energy, biogases and biofuels. The conclusions drawn from the research point out to the fact that the development of renewable energy in Poland is growing slowly but surely. In 2011, the share was at 9.5% and by 2015 it grew to 11.8%, with the target set for 2020 being at the level of 15.0%. The production of energy from renewable sources is improving (from 7.5 to 8.1 Mtoe). Nevertheless, the share of primary energy obtained from renewable energy sources in the total primary energy is less than half of the EU share. The data showcase that the projected aim is likely to be achieved; however, the few years to come should envisage some intensification of activities oriented to this goal. Biomass now enjoys the dominant role but its significance is gradually waning, which favours wind energy and biofuels. The projected directions of renewable energy development indicate that this sector is going to be a significant factor in implementing the sustainable development policy in the years to come.

The article deals with the use of renewable energy sources in construction in general and in high-rise unique buildings. Such approach will allow to design and construct buildings in which integrated renewable energy sources can be perfectly applied to all aspects of construction. The historical development of architecture and ecology as a single phenomenon is considered. This is particularly relevant to high-rise buildings. With the implementation of energy-efficient technologies, the main drawback - high-energy consumption - will be cut off. The article raises the question of the need to merge these two concepts. Examples of buildings with applied renewable energy sources, both constructed and projected, are considered. Non-traditional energy sources such as wind, solar, land, water and biomass are analyzed. The relevance of their application in construction and influence on all aspects of the project is proved: town-planning, functional, space planning, architectural and artistic, constructive and engineering.

To ensure proper gas supply parameters, to the polish natural gas distribution network, which includes about 900 pressure reduction stations (PRS), requires high energy consumption for gas heating, that amounts to approx. 700 TJ/year. This value can be significantly reduced by using renewable energy sources (e.g. ground heat exchangers, heat pumps) in polish gas preheating PRS. This paper presents the analysis of some applications for gas preheating by using gas absorption heat pump and combination of heat pump and ground heat exchanger. The results confirm a noticeable heat energy savings at the PRS by 44%.

Electrical energy is one of the most important daily needs. Shortage of energy can be very dangerous for any society. This can affect the standard of living and quality of life of the people and even endanger the lives of those in hospitals, and so forth. Developed countries do not face such risks in general because they have well organized electrical systems and high energy security. The developing countries are faced daily with electric system collapses, especially in the case of wars, where many parts of the electrical grid in the country can be damaged and fuel transmission lines for generators cut off. Urban areas in developing countries should have a strategic plan to deal with any unexpected occurrence of energy shortages using any available renewable energy sources. City of Latakia is located in the region which has been suffering from the consequences of war for more than six years. The fact that a high number of migrants from other cities have come to Latakia along with a lack of fuel makes the energy shortage in the city worse. An emergency system could use the cheapest available renewable energy sources in addition to few big portable generators to provide an acceptable energy supply for the most needed requirements of daily life.
