In this compilation, the authors first present a study in which computational design is performed, using empirical data, to fit physical models to extract transport and material parameters (which are then used in 1D continuum and 3D particle models of charge transport) to validate against empirical measurement and each other prior to use in extrapolation studies.Next, the book aims to discuss and illustrate the key trends behind the current international and European Union energy and climate policy. The authors provide insights into current dynamics, enabling a better understanding of future developments and indicating that unless a global effort to reduce greenhouse gas emissions is made, emissions will continue to rise.The authors also present a computer algorithm based on type-1 fuzzy logic control strategies to manage the flow of energy in stand-alone PV/Wind/Battery hybrid systems. The solar and wind energies were combined together to increase system's efficiency and batteries were used to ensure the availability of power on demand and improve the dynamic behavior of the system.Both traditional and state-of-the-art proteomics techniques used for quantification of corn stover hydrolyzing enzymes are presented in the following chapter.

In the past, fossil fuels have been considered a reliable source of energy by many countries. Despite the current measures to reduce the use of fossil fuels for electricity generation, the use of this type of energy source will continue for the foreseeable future. This book examines how, if this situation does not change in the future, then all types of fossil fuels, particularly oil, will be exhausted before the end of the current century. The use of microholes may potentially enhance the applications of fossil fuels in various energy fields, especially in thermal power plants. Therefore, the morphology variation of micropunch and microhole during the punching with WC/Co micropunches is investigated in this compilation through scanning electron microscopy, energy dispersive spectrometer and confocal laser studies. Following this, the authors provide a review on experimental and modeling studies performed with direct fuel cells, starting with the fundamentals and main drawbacks of these systems, followed by an exhaustive review on the different studies performed regarding the effects of operating conditions and design parameters. In the penultimate chapter, a new method for determining the cohesion potential energy in solids is described, and fundamental factors such as internal energy, entropy, temperature and time are examined, in particular the connection of entropy and time to potential energy. The method concerns molecular solids and rests upon measurable thermodynamic quantities: heat of sublimation, heat capacity, and entropy as derived from the latter. The closing chapter provides an overview of three methods (retarded osmosis method, forward osmosis-electrokinetic method, and diffusio-osmotic method) for sustainable power generation from the salinity gradient energy by using osmosis-based processes.

This book opens with a comprehensive review of technologies for the reutilisation of waste cryogenic energy from the liquefied natural gas regasification process at terminals and on marine vessels. The authors discuss the primary renewable energy source in Cuba — biomass. Although sugarcane biomass has the most significant energy potential, some other biomass energy sources are also relevant at the local level and are convenient from an environmental standpoint. Invisibility cloaks of various types have been researched extensively in recent years with one of the first being the electrostatic cloak, so-named because it effectively screens an internal volume from, and offers no disturbance to, an external static electric field. As such, this compilation explores this phenomenon and whether the cloaked object (or the cloak itself) could be detected by various means. The concluding study explores how, in order to reduce the consumption of oil for electricity generation by 20% in Cuba, the country should build a total of 13 wind farms with a capacity of 633 MW.
