“…Although hydropower technology mitigates greenhouse gas emissions from fossil fuel, the construction of hydropower dam creates a negative impact on the environment. To construct a dam large land was cleared lead to soil erosion problem, disruption on the ecosystem near the dam site and the farming land decrease [50].…”

The ASEAN population will increase to 724.8 million by the year 2030 and the urbanization rate increases with years. This leads to the development of the construction industry to fulfil the fundamental social and physical requirements. Construction activities create an adverse negative impact on the environment, such as pollution and damage to the environment. This article will study more about the construction and demolition waste (C&D waste) and it can be founded in various construction stages. Therefore, the government and authorities introduce environmental management practices to mitigate the negative impact on construction on the environment and minimize the pollution at the source. What, why and where are terms required to consider before the implementation of environmental management practice. The government policies of Malaysia, Singapore and Thailand are summarized. Approximately 10% of total synthetic carbon dioxide (CO2) sourced from concrete production. The content more emphasizes the green materials generated from agricultural waste to replace the silica in concrete. The bamboo is used as interior decoration and material for building construction. Green materials technology is solar panel, solar thermal collector, geothermal technology, hydropower technology and cooling roof system.

“…On the other hand, PV systems consist of solar modules only. Consequently, it is reliable, easy to scale-up, 10 and also has a relatively low installation cost. Hence, where electrical energy generation is concerned and the application is of small scale, which also constitutes the scope of this work, PV technology is a naturally attractive choice.…”

With the growing demand for energy and increasing environmental concerns, there is an imminent requirement for a paradigm shift from nonrenewable sources toward renewable sources for energy generation. Among the emerging technologies, the photovoltaic (PV) system holds immense promise due to the abundant availability of the source (solar irradiance), low installation cost, and ease of scale-up. It is known that the efficiency of a PV system, not-withholding its dependency on other factors, decreases with an increase in the module temperature. The module temperature in turn is a function of disturbances, especially, intermittent weather variables, solar irradiance, ambient temperature, and wind speed. In this work, we propose, develop, and design a module temperature control system consisting of an adaptive model predictive controller that manipulates the flow rate of a water coolant flowing on the module. The controller design is based on (i) an expression for computing the PV efficiency as a function of time and (ii) an improvised comprehensive thermal model that accounts for the effects of disturbances and the coolant flow on the module temperature. The adaptive model predictive controller is tuned based on a trade-off between achieved control error and control effort. Further, an optimal set-point (for the module temperature) that achieves a desirable trade-off between the average power gain (due to temperature control) and the power consumed (due to coolant pump) is determined through numerical/simulation studies. In silico simulations on two geographical regions demonstrate that the proposed control scheme results in a maximum improvement in efficiency of nearly 10%.

“…This paper demonstrates the full operational suitability of the tested blends. A broad analysis of various fuels in terms of their influence on engine vibrations is carried out in [35][36][37], whereas various techniques of vibration measurement, depending on the properties of biofuels, are the focus of works [38][39][40]. The study [41] narrows down the area of diagnostic research on the influence of biofuels on cylinder liners, and [42] discusses the issue of vibration testing of the entire engine block powered by alternative fuel.…”

Comparison of Diesel Engine Vibroacoustic Properties Powered by Bio and Standard Fuel

Alternative fuels appeared soon after the first internal combustion engines were designed. The history of alternative fuels is basically as long as the history of the automotive industry. Initially, fuels whose physicochemical properties allowed for a change in parameters of the combustion process in order to achieve greater efficiency and reliability were searched for. Nowadays, there are significantly more variables; in addition to the above mentioned parameters, alternative fuels are being sought that will ensure environmental protection during vehicle operation and improve the ergonomics of use. This article outlines the results of the authors’ own comparative tests of vibrations of a vibroacoustic character. Based on a popular engine model, the vibration–acoustic responses of a system powered by two types of fuel, namely, diesel and biodiesel (B10), are compared. The research consists of comparing vibrations in both time and frequency domains. In the case of the time domain, the evaluation was performed with vibrations as a function of engine torque and speed. In the case of frequency analysis, the focus was on changes in the frequency response for the tested fuels. The research shows that the profile of vibroacoustic vibrations changes in the case of biodiesel power supply in relation to standard fuel. The vibration profile changes significantly as a function of speed and only slightly in relation to the engine load. The results presented in this article show different vibroacoustic responses of an engine powered by diesel and biodiesel; the change is minor for lower speeds but significant (other harmonics are dominant) for higher speeds (changes in the dominant harmonic magnitude of up to 10% at a crankshaft speed of 3000 rpm).
