But increasing input cost of cement manufacturing, decreasing margin of profit, scarcity of raw coal availability and emission of greenhouse gases are some constraints, which restrict the growth of cement industry. Hence to combat with all these adverse situations simultaneously, this project report introduces and efforts to generate clean and green energy with the help of combination of preheater tower, which is available in all integrated cement plants and an augmented wind turbine. Hence, the technology is named as “Power Producing Preheaters” or 3P.H. Introduction of 3P.H. in cement industry, generates a definite amount of clean and green energy (as per site conditions), which is directly used in cement production to avoid grid connectivity cost of wind turbine output. Calculations are done to show the overall cost of project, its payback period and reduction in emission of greenhouse gases along with its benefits in cement industry.展开更多

The development of clean energy requires a considerable amount of R ＆ D （research ＆ development） expenditure and various core technologies, and therefore, international research collaboration is necessary for prompt and efficient development. The study is aimed at establishing a knowledge base that can help to prepare international research collaboration policies for solving global challenges effectively. The authors demonstrate the research capacity and international research collaboration in solar cell and fuel cell technologies, using global research network diagrams gathered from 35,322 and 33,136 academic papers, respectively. The diagrams include the data of research competency and co-authorship. More than 6,000 institutions and 100 countries are involved in each field. Based on the diagrams, the technologies are compared and international collaboration is analyzed. A valley of research collaboration in Asia is identified for both technologies.

This aspect is frequently underappreciated, yet studies indicate it could be a significant area of environmental impact. For instance, research has shown that a typical electric vehicle needs around six times the mineral resources of a conventional vehicle, while an onshore wind turbine requires nine times the mineral input compared to a gas power plant of similar capacity. This paper seeks to analyze the environmental effects linked to the critical minerals required by certain renewable energy technologies. The study begins with an estimation of the future megawatt capacities for each type of renewable technology. Next, it calculates the specific mineral quantities necessary for each model, followed by an assessment of the environmental repercussions tied to their extraction and processing. The results highlight the unique environmental challenges posed by the rising demand for minerals in solar and wind energy systems, taking into account various adoption scenarios.展开更多
