Distributed Energy Generation

Ecological and environmental governance is vital to global sustainability. The role of energy saving in achieving CO2 emissions reductions is known to be important for environment protection . PPPs governance in DEG can be considered key to driving down traditional energy demand and hence CO2 emissions in the coming sustainable economy. Over the coming decade, Centralized Energy Generation (CEG) will decline relative to Distributed Energy Generation (DEG) such as solarphotovolatic, microturbines, fuel cells, combined heat and power and variety of renewable energy. This shift promises to improve power reliability, deliver cleaner power and avoid significant investments in transmission infrastructure. As an integrated hybrid governance system of sustainability, PPPs enjoys high efficiency of governance via collective efforts of multi-agents involved. In order to promote the governance quality of DEG, it is of importance to harness the advantages of integration of PPPs Governance in DEG project. This paper examined PPPs governance in order to improve efficiency of Distributed Energy Generation, it firstly briefly outlines the profile of PPPs, then illustrates the essentials of good PPPs governance in global DEG governance context. Finally, it draws the conclusion that how to ensure the efficiency of PPPs in collective governance of DEG projects.

The introduction of semi conductors changed the world which made our electronic devices and personal computers simple and complex this impact made many companies to introduce lot of computer organized devices which are available to commoners and every individual due to this within a years the usage of these items increased that means the material demand increased in a fast forward the pollutants from it also increased which is harming environment. So, in order to save environment green computing must be followed this topic is very important as how recycling, non-biodegradable components, eco friendly products, hazardous CFCs all comes under this including energy saving, efficiency providing things, sustainable resources. This presentation gives a general overview on the current state of opportunities which are seeing it as a way to create new profit centers while trying to help the environment cause and several formations that we can explore in it in coming future. The new electronic products and services with optimum efficiency and all possible options towards energy saving.

AbstractPerovskite solar cells (PSCs) emerging as a promising photovoltaic technology with high efficiency and low manufacturing cost have attracted the attention from all over the world. Both the efficiency and stability of PSCs have increased steadily in recent years, and the research on reducing lead leakage and developing eco-friendly lead-free perovskites pushes forward the commercialization of PSCs step by step. This review summarizes the main progress of PSCs in 2020 and 2021 from the aspects of efficiency, stability, perovskite-based tandem devices, and lead-free PSCs. Moreover, a brief discussion on the development of PSC modules and its challenges toward practical application is provided.

Viscoelastic Surfactant

Although new energy has been widely used in our lives, oil is still one of the main energy sources in the world. After the application of traditional oil recovery methods, there are still a large number of oil layers that have not been exploited, and there is still a need to further increase oil recovery to meet the urgent need for oil in the world economic development. Chemically enhanced oil recovery (CEOR) is considered to be a kind of effective enhanced oil recovery technology, which has achieved good results in the field, but these technologies cannot simultaneously effectively improve oil sweep efficiency, oil washing efficiency, good injectability, and reservoir environment adaptability. Viscoelastic surfactants (VES) have unique micelle structure and aggregation behavior, high efficiency in reducing the interfacial tension of oil and water, and the most important and unique viscoelasticity, etc., which has attracted the attention of academics and field experts and introduced into the technical research of enhanced oil recovery. In this paper, the mechanism and research status of viscoelastic surfactant flooding are discussed in detail and focused, and the results of viscoelastic surfactant flooding experiments under different conditions are summarized. Finally, the problems to be solved by viscoelastic surfactant flooding are introduced, and the countermeasures to solve the problems are put forward. This overview presents extensive information about viscoelastic surfactant flooding used for EOR, and is intended to help researchers and professionals in this field understand the current situation.

Buildings consume many resources and generate greenhouse gases during construction. One of the main sources of greenhouse gases is carbon emission associated with buildings. This research is based on the computing rule of carbon emission at the materialization stage. By taking the features of green construction into consideration, quantitative analysis on construction carbon emission was undertaken via Life Cycle Assessment (LCA). Making use of Vensim (a system dynamics software package), we analyzed the amount of carbon emission at the materialization stage and determined the major subsystems affecting the carbon emission, then took into comprehensive consideration the differences of each subsystem’s carbon emission under different construction technologies. Under the mechanism of carbon trade at the materialization stage, the total price of carbon trades remains unchanged, while the trading price of each subsystem is adjusted. Under these conditions, a coefficient for step-wise increases in carbon price was proposed. By establishing such a system of gradient prices, construction companies are encouraged to adopt high-efficiency emission reduction technologies. Meanwhile, the system also provides a reference for the formulation of price-based policies about buildings’ carbon trading, and accelerates the process of energy conservation and emission reduction in China and the world at large.
