The book deepens understanding of biomass sources and technologies used for cooking worldwide. It contributes directly to the creation of policies aimed at the mitigation of climate change.Historically, wood is considered humanity's first source of energy. Even after decades of use and industrialization processes, it is still considered the most important single source of renewable energy. About a third of the world's population is energetically dependent on wood for cooking and/or heating. Recently, the Covid-19 pandemic made it impossible to purchase fuels such as liquefied petroleum gas (LPG), forcing families in financial difficulties to opt for cheaper and more accessible sources of energy, such as wood and vegetable coal. This has been the picture of many families around the world and negatively impacts the environment and energy security. Considering that there are still many wood residues that are wasted and that tropical forests need to be conserved, knowledge aboutthe energy use of wood residues is also essential. This is even more relevant when considering the significant volume of biomass coming from the sustainable management of the largest tropical forest in the world, the Amazon Forest.The book considers which wood variables should be taken into account when thinking about energy generation, how do food cooking technologies contribute to potentiating pollutants emissions, and how can these harmful effects be mitigated. It describes the chemical composition of biomass and the chemical compounds released during its burning, as well as their impacts on the environment and human health. It also presents the influence that technologies used in food cooking have on pollutant emissions and which alternatives can be used, such as the use of solar energy.

This book gives you theory and design of PV/T systems. Are you interested in solar energy? If you are, you must have read about solar panels, or photovoltaics (PV). If you have installed a photovoltaic system, you must have noticed it not to generate the amount of power mentioned in its datasheet. A major issue that PV suffers from is its temperature, which causes a drop in its power. Among the solutions to this issue is to use active cooling methods, such as the hybrid photovoltaic thermal (PV/T) system. These systems can produce electrical and thermal energy simultaneously and within same area. The thermal collector serves to cool down the PV surface temperature, which negatively affects the PV efficiency, to reclaim the efficiency or bring it back close to standard testing conditions value. Moreover, the thermal collector will convey this heat using a working fluid and extract it as thermal energy. On the other hand, the electrical power generated from the PV can be utilized in standalone or grid-connected configuration. Moreover, the book presents a novel PV/T collector which can utilize nanofluids and nano-Phase Change Material (PCM) to enhance its performance in tropical climate conditions. The methods used to develop the heat transfer and energy balance equations are presented as well.
