Nanotechnology, Solar, Wind, and Hybrid Alternative Energy


Book Description

In this book, the global implications of solar, wind, or hybrid as an alternative energy is critically examined and explained. In Brazil, China, Canada, Cuban, Germany, Nigeria, Swiss, and the United States, leadership styles affect finding alternative sources of energy that will complement fossil fuels, hydro, or nuclear power supply. We explain, contrast, and compare various global leadership perspectives as its affect alternative energy sources. Leadership styles and political considerations become the trajectories in the introduction of innovative disruptive technologies. Seven billion people worldwide have inadequate supply of energy (United Nations, 2010). In developing nations, hydropower supply has resulted in consistent brown outs. In developed nations, the lack of clean nuclear power raises safety concerns. In rural areas in developed nations, fossil fuels, hydropower, and nuclear power have not met the demand for energy supply (Jeter, 2004; Ogden, 1999).The background of solar, wind, and nanotechnologies are congruently explained. Nanotechnology is introduced and elements within the innovative systems are considered disruptive technologies. Nanotechnology as a disruptive technology includes capability of self-replicating machines, robots, and the production of molecular sized computers (Merkle, 2009; Uldrich, 2006). Nanotechnology as a disruptive technology also has the capacity to improve human lives globally.Hypothesis deduced from this study revealed that solar, wind, or hybrid could not replace hydropower or nuclear power, rather should complement the existing energy supply. Solar, wind, or hybrid should however disrupt the existing systems to the point of setting new paradigm; to shifting new frontiers in global mindset and reasoning (Martins, Ruther, Pereira, & Abreu, 2008). Situational leadership style trumps other form of leadership styles in the implementations of alternative energy and while introducing nanotech from proposal to fruition. We conclude this study by explaining factors embedded in the decision-making processes of introducing the benefits of alternative energy globally.




Nanotechnology Applications in Green Energy Systems


Book Description

"This book will be beneficial for students, researchers and scientists working in the field of green energy systems. In the last few decades, green energy technologies have gained significant interest. The increase of heat transfer in green energy technologies is one of the most important concerns in energy collection, energy storage, energy utilization, energy conservation, and optimum design. Since nanofluids/nano-enhanced phase change materials are used to increase heat transfer characteristics and thermal properties compared to conventional fluids/phase change materials, the performance of green energy technologies can be improved. These novel strategies are gaining interest to researchers and authors in recent years. This book presents the various applications of nanofluids, hybrid nanofluids, and nano-enhanced phase change materials in green energy technologies such as solar thermal energy storage, photovoltaic/thermal systems, tracking and non-tracking solar collectors, solar thermal power plant, and wind turbine cooling systems. The thermophysical properties of the nanofluids and nano-enhanced phase change materials are also presented. This book also overviews the challenges and opportunities in implementing the nanofluids/nano-enhanced phase change materials application in green energy technologies"--

Nanotechnology for Sustainable Energy


Book Description

Increased energy prices and the growing attention on global warming are motivating the creation of economically viable alternatives to fossil fuels. Nanotechnologies have been recognized as one effective approach to solve energy problems. Therefore, to promote the improvement of research and to foster professional collaboration among researchers in energy-related nanotechnologies, we organized a symposium on "Nanotechnology for a Sustainable Energy Economy" as a part of the 243rd American Chemical Society National Meeting, which took place March 25-29, 2012 in San Diego, California, USA. Forty-four contributors from 12 countries presented their research works from industrial, university, and national laboratories in nanotechnology areas related to energy and fuel technologies. This ACS Symposium Series book was developed from this symposium. This book presents a very useful and readable collection of reviews and research papers in nanotechnologies for energy conversion, storage, and utilization, offering new results which are sure to be of interest to researchers, students, and engineers in the field of nanotechnologies and energy. The book focuses on the following topics: Li batteries (Chapters 1-4), supercapacitors (Chapter 5), dye-sensitized solar cells (Chapter 6), photocatalysis (Chapters 7-9), fuel cells (Chapter 10), electrocatalysis (Chapter 11), and electron beam lithography (Chapter 12). All 12 chapters were recruited from oral presentations at the symposium.




Hybrid Renewable Energy Systems


Book Description

The energy scene in the world is a complex picture of a variety of energy sources being used to meet the world's growing energy needs. There is, however, a gap in the demand and supply.

The Influences of Big Data Analytics


Book Description

The theoretical framework for this book was our ground-up theory of the Scope, Size, Speed, and Skill (4Ss) and Technological Situational Happenstances (TSHs) applied to Big data analytics. With in-depth research, we catechized the effects of the coalesced insights from big data influencing the architectures of incremental and radical business models. We discussed data inflation and the global impact of TSHs. We showed how deft leadership used insights gleaned from big data analytics to make strategic decisions. The big data syndrome led to Microsoft's acquisition of Nokia in our case study. Our study of APPLE Corporation's use of large datasets was explicitly analyzed. Leaderships' failure to incorporate those contextual elements afforded by insights gleaned from big data analytics, concomitant with the associated costs led to acute forms of irrational rationalism, groupthink, and faulty decision making. We explained the statistics used to essentially describe this paradigm shift, such as high dimensionality, incidental endogeneity, noise accumulation, spurious correlation, and computational costs. Significantly, machine learning challenged the status quo by effectively changing the existing technological landscape. To scholarly critics, how would supervised and un-supervised learning algorithms advance the trajectory of perspectives in applied knowledge under the umbrella of big data? Further, political and socio-economics tied to big data was examined. We recommended leaders should have a shared cognition on how to leverage analytics from large datasets for competitive advantages. Most significantly, leaders or managers should be cognizant of the inextricable synergies that seamlessly flow from adroitly implementing a strategy to profit from the speed, size, skill, and scope (i.e. the 4Ss) of the big data environment, conditioned by the leveraging of those transactional situational happenstances generated by increases in market volatility. We concluded the algorithmic processes of leveraging insights from big data have globally resulted in a disruption of current technological pathways.
