This study has covered many types of solar-powered air-conditioning systems that may be used as an alternative to traditional electrically powered air-conditioning systems in order to reduce energy usage. Solar adsorption air cooling is a great alternative to traditional vapor compression air-conditioning. Solar adsorption has several advantages over traditional vapor-compression systems, including being a green cooling technology which uses solar energy to drive the cycle, using pure water as an eco-friendly HFC-free refrigerant, and being mechanically simple with only the magnetic valves as moving parts. Several advancements and breakthroughs have been developed in the area of solar adsorption air-conditioners during the previous decade. However, further study is required before this technology can be put into practise. As a result, this book chapter highlights current research that adds to the understanding of solar adsorption air-conditioning technologies, with a focus on practical research. These systems have the potential to become the next iteration of air-conditioning systems, with the benefit of lowering energy usage while using plentiful solar energy supplies to supply the cooling demand.

Research to find new energy source is still an intensive work by researchers in this field. One of the energy sources with no negative impact to environment is solar energy. Solar cell is used to convert solar energy to electrical energy. The electrically powered solar cell in direct current (DC) power is not suitable for our daily office equipment since they need the alternating current (AC) power. This research has succeeded in realizing a solar cell automation tool based on Arduino Uno with input from solar energy, from which output AC voltage can be used for the needs of household appliances and office equipments. Output power of this tool is approximately 700 W, which can turn on the lights, charge the hand phones, laptops, and so forth.

The chapter will explore the growth and opportunities of small-scale local power generation and the implications for internet access for rural communities. Solar power has grown exponentially in the last decade across the world and has provided opportunities for the development of local energy communities and on microgrids across the world and in Europe.

The huge cost reductions experienced in solar and its relative mobile and flexible nature have made it a technology perfect for rural areas to develop their own sustainable source of electricity supply. The increasing rise of digital tools has coupled nicely with the advent of mass use of solar in rural areas and thus the connection between smart solar and smart villages has become increasingly a norm.

Rural communities in Europe have embraced solar technology, with many farmers using solar as a means to reduce their electricity costs and also generate new streams of income to improve their overall livelihoods. Some case studies from India, Germany, and Africa will be examined. Other experiences will also be considered, especially where double land use between solar technology and livestock has empowered rural communities.

Outside of Europe, Africa and Asia have also seen solar as a means to electrify remote rural villages. This has lead to the development of microgrids and new technologies that are less deployed in Europe, which are being rolled out for rural communities in the rest of the world. This has been particularly successful in creating smart rural communities as often digital communications have already reached these communities and thus power and telecoms are combining to provide clean and controlled power for millions in Africa. This chapter will also assess the growth of smart energy communities in non-traditional energy markets and determine what lessons we can learn from their experiences.

This chapter will examine other sources of renewable energy and the role that biogas, biomass, and others are playing in the creation of smart villages in Europe and beyond. Biomass has been the traditional tool for many rural communities to generate power and heat and thus an examination of how it now plays a role in smart villages is vital to understanding the energy transition we are experiencing in rural communities.

The environmental impact of energy supply is growing which has a significant impact on regional and global environmental issues. As a solution for this, both developed and developing nations paying attention to convert their energy productivity by using renewable energy like wind and solar energy. Sri Lankan government also aims to obtain the full amount of electricity required from local renewable sources by the year 2050 under the project called “sooryabala sangramaya” (the battle for solar energy). Currently, Sri Lanka’s power generation sector is heavily dependent on imported fuels, such as petroleum and coal, resulting in growing detrimental impacts on the country’s sustainable socioeconomic development. With the growing market of solar photovoltaic (PV) technology, Sri Lanka is turning its attention towards generating the total amount of electricity required from solar power by promoting the installation of arrays of PV panels on the rooftops of households, religious places, hotels, commercial establishments and industries. It also aims to deploy solar PV for sustainable rural development, mainly focused on uplifting people living in remote areas in the country. This chapter discusses how Sri Lanka has initiated a rooftop solar PV adoption program to lessen imported fuels’ socioeconomic and environmental impacts. Moreover, this case demonstrates that the adoption of rooftop solar PV brings many socioeconomic benefits to its consumers.

Uzbekistan easily gets 300 days of sunshine a year, and is a natural choice for development of solar technologies and their implementation. Central Asia is working together to solve critical water problems including contamination and dry wells. This chapter addresses the need to find solutions for rural populations living in the shadow of the Aral Sea disaster, with poor quality drinking water and limited infrastructure. With assistance from generous government funding, the Institute for Solar Energy is developing new point-based solar desalinization and pumping technologies. Preliminary designs are promising and government support for raw materials mining and wafer production are growing. Domestic R&D and production ensures cost-effective dissemination options. The Institute houses both research and project management for all solar technologies and expects to field test prototypes within 2–3 years. Solar energy is a growing sector in the economy of Uzbekistan.

This case discusses the journey of SELCO Foundation, a Bengaluru based not-for-profit organization. It provides key learning and insights for social transformation and poverty alleviation. With the vision of “creating inclusive development pathways that were socially and environmentally sustainable,” the Foundation fostered and scaled ecosystems for democratization of access to clean energy and sustainable solutions for the marginalized communities. Using decentralized renewable energy (DRE), SELCO’s initiatives had established linkages between SDG7 (Affordable and Clean Energy) and SDG3 (Good Health and Well-being), SDG4 (Quality Education), SDG8 (Decent Work and Economic Growth), and SDG11 (Sustainable Cities and Communities). Throughout its journey, it continuously challenged normative development paradigms and perceptions about gender issues, poverty, and sustainability as a whole through a people-centric approach; empowering individuals, communities, and institutions. The recent COVID-19 pandemic landed a massive blow to the country’s socioeconomic structure. SELCO Foundation’s teams deployed in remote locations for livelihood interventions programs had faced a multitude of challenges due to COVID-19 lockdown. As a response to COVID-19 crisis, SELCO Foundation rallied its resources to support relief efforts across India. It leveraged its expertise in energy by deploying a pan India network of grass-root partners; community-sourced innovations to ramp-up last mile healthcare infrastructure, build community resilience programs, and strengthen existing capabilities. Leveraging sustainable solutions as a medium, SELCO’s transformative work extended beyond access to clean energy, and sought to address complex issues such as healthcare, education, reduction in drudgery in manual jobs, creating opportunities for dignified work and more. Through this case study, this chapter discusses the emergence, journey, and initiatives of SELCO Foundation. It explores a practice-based pedagogy of social transformation, and challenges faced in ecosystem building during the times of the pandemic. The chapter initiates a discussion for a way forward for the social enterprise in times of uncertainties and stringencies in order to continue impacting underprivileged lives to the best.

This chapter seeks to place the Paris agreement on anthropogenic greenhouse gases (COP21) in a wider picture on how the global solar photovoltaic (PV) market has been created and shaped over decades. The chapter discusses the role of solar PV actors, as well as other actors in the market-shaping process. The aim is to show how the COP21 can be interpreted in a wider historical perspective.

The chapter builds on expert interviews conducted after the COP21, as well as secondary data on historical studies on evolution of solar energy markets in various countries.

Although scientists and entrepreneurs have been important in creating and shaping the global solar PV market, it is noted that other actors have also had an influence on the market development. Particularly, politicians are seen as playing a crucial role through legislation and funding. Unfortunately for the solar PV market, support has fluctuated over time. The COP21 provides a clear pathway for positive support, and it is expected to bind governments for pro-solar politics even during low prices of fossil fuels and economic downturn.

The chapter provides an overview of what has happened in the history of global solar PV market. It gives reasoning as to why the COP21 is important in securing support for the solar PV market. Thus, it can provide reasoning as to why the COP21 can make a difference.

This is the first academic study that portrays the COP21 against historical evolution of the global solar PV market.

Reviews the environmental improvements that may be conferred through the adoption of alternative aviation fuels and new airframe, engine and navigation technologies.

Although aeronautical technologies have evolved considerably since the earliest days of powered flight, the aviation industry is now reaching a point of diminishing returns as growing global consumer demand for air transport outstrips incremental improvements in environmental efficiency. The chapter describes some of the technological interventions that are being pursued to improve aviation’s environmental performance and discusses the extent to which these innovations will help to deliver a more sustainable aviation industry.

Energy consumption in transportation accounted for over 29% of total final consumption (TFC) of energy and 65% of global oil usage, and it is highly connected to mobility. Mobility is essential for access to day-to-day activities such as education, leisure, healthcare, business activities, and commercial and industrial operations. This study examines the energy consumption for the transport industry, and the level of renewable energy development in some selected Sub-Saharan African (SSA) nations. This study relied on previous publications of government, reports and articles related to the subject matter. Vehicle ownership is fast increasing, particularly in cities. Still, it begins at a relatively low level because the area is home to countries with the lowest ownership rates worldwide. In its current state, the energy sector faces significant challenges such as inadequate and poorly maintained infrastructure, dealing with increasing traffic congestion in cities, large-scale imports of used vehicles with poor emission standards that affect air quality in cities, a lack of safe and formally operated public transportation systems, and inadequate consideration for women and disabled mobility needs. Motorcycle and tricycle are dominating the rural areas, accounting for a substantial amount of this growth. Aviation is the largest non-road user of energy, and this trend is predicted to continue through 2040 as Gross Domestic Product (GDP) grows and urbanisation expands. This study revealed the energy consumption for the transport industry, and the level of renewable energy development in some selected SSA. Rail and navigation lag behind current global levels. The usage of biofuel and rail transport was recommended.
