The book starts with an overview of the role of cities in climate change and environmental pollution worldwide, followed by the concept description of smart cities and their expected features, focusing on green technology innovation.

This book explores the energy management strategies required to minimize the need for huge investments in high-capacity transmission lines from distant power plants. A new range of renewable energy technologies modified for installation in cities like small wind turbines, micro-CHP and heat pumps are described. The overall objective of this book is to explore all the green and smart technologies for designing green smart cities.

1.1 Introduction

There has been a remarkable growth in the percentage of the world’s population living in urban areas. Presently, almost 55% of the world’s population lives in urban areas and it is expected that the urban population will account for 66% of the world’s population by 2050 (United Nations 2018). Significant advancements in society and a deficiency of resources in rural areas have led to a continous migration of the rural population to urban areas. Table 1.1 presents the projected growth rate of the world’s population from 2020 to 2050, including the urban population percentage. Figure 1.1 shows the percentage of the urban population in the ten most populated countries. This expansion into urban areas requires the optimization of available resources (such as electricity, water, housing and transportation) to meet the needs of citizens. Therefore, emerging technologies such as artificial intelligence, cognitive technology, Internet of Things, machine learning and cloud computing are now being used in a significant manner to convert cities into “smart cities”. Energy-efficient green communication and seamless networking are very important pillars of smart city construction, and connect the different essential elements of smart cities. This chapter aims to provide a brief definition of smart cities and to summarize the various emerging technologies which play a vital role in smart cities.

(Shahidehpour et al. 2018).

Over the past 50 years, the average growth rate of the world’s population has been almost 1.2% per year (Roser et al. 2013). The urban area population has continuously surpassed the rural area population and it is expected that this will continue, with the urban population accounting for 68.5% of the total population by 2050 (Mensah et al. 2019). Therefore, the present scenario is one of greater urbanization. There are many benefits of urbanization but it also brings many challenges. Increased urbanization means increased demand for various resources such as electricity, water, transportation, sanitation and infrastructure, as well as healthcare, public services and education. The urbanization process also plays a key role in environmental degradation on a local, regional and global level.

At the present time, the conversion of digital cities into smart cities is a major issue of concern for many countries. Intelligent and digital cities are those which are technology-oriented but a city becomes “smart” when it is organized, interconnected, self-repairing, self-decision-taking and healthy. In the literature, various models and explanations have been put forward for smart city description (Wenge et al. 2014). Figure 1.2 presents a layered architecture model for a smart city. This model consists of seven layers of a smart city, in which each layer plays a very important role. A central role is performed by the third layer (i.e. the communication and networking layer). The first layer is infrastructure, which consists of roads, buildings, the electricity grid and parking.

The communication and networking layer facilitates and supports the different forms of communication such as voice, text, data, video, multimedia and real-time services from a personal area network (PAN) to a wide area network (WAN). A question that emerges is how communication and networking provid...
