The world is at a pivotal crossroad in energy choices. There is a strong sense that our use of energy must be more sustainable. Moreover, many also broadly agree that a way must be found to rely increasingly on lower carbon energy sources. However, no single or clear solution exists on the means to carry out such a shift at either a national or international level. Traditional energy planning (when done) has revolved around limited cost projections that often fail to take longer term evidence and interactions of a wider set of factors into account. The good news is that evidence does exist on such change in case studies of different nations shifting toward low-carbon energy approaches. In fact, such shifts can occur quite quickly at times, alongside industrial and societal advance, innovation, and policy learning. These types of insights will be important for informing energy debates and decision-making going forward. Low Carbon Energy Transitions: Turning Points in National Policy and Innovation takes an in-depth look at four energy transitions that have occurred since the global oil crisis of 1973: Brazilian biofuels, Danish wind power, French nuclear power, and Icelandic geothermal energy. With these cases, Dr. Araújo argues that significant nationwide shifts to low-carbon energy can occur in under fifteen years, and that technological complexity is not necessarily a major impediment to such shifts. Dr. Araújo draws on more than five years of research, and interviews with over 120 different scientists, government workers, academics, and members of civil society in completing this study. Low Carbon Energy Transitions is written for for professionals in energy, the environment and policy as well as for students and citizens who are interested in critical decisions about energy sustainability. Technology briefings are provided for each of the major technologies in this book, so that scientific and non-scientific readers can engage in more even discussions about the choices that are involved.

The production of primary aluminum is an energy-intensive industry which produces large amounts of direct and indirect greenhouse gas emissions, especially from electricity consumption. Carbon Emissions Constrained Energy Planning proved to be an efficient tool for reducing energy-related greenhouse gas emissions. This study focuses on energy planning constrained by CO2 emissions and determines the required amount of CO2 emissions from electricity sources in order to meet specified CO2 emission benchmark. The study is demonstrated on and applied to specific aluminum products, aluminum slugs and aluminum evaporator panels. Three different approaches of energy planning are considered: (i) an insight-based, graphical targeting approach, (ii) an algebraic targeting approach of cascade analysis, and (iii) an optimization-based approach, using a transportation model. The results of the three approaches show that approximately 2.15 MWh of fossil energy source should be replaced with a zero-carbon or 2.22 MWh with a low-carbon energy source to satisfy the benchmark of CO2 emissions to produce 1 t of aluminum slug; however, this substitution results in higher costs. This study is the first of its kind demonstrated on and applied to specific aluminum products, and represents a step forward in the development of more sustainable practices in this field.

The prospects of biogas as a major energy option to alleviate the energy needs in Africa is huge based on its teeming population. However, the main source of biogas i.e. human excretal is being neglected, thereby loosing resource worth 500 MW of electricity. This research is geared towards estimating the accruable biogas that can be harnessed in a typical student hostel in a developing country. The data was collected at the main chamber of the hostel. The estimation of the optimized state of methane, hydrogen sulphide and carbon dioxide is given as 12%, 0.94% and 4.42% respectively. It was also affirmed that the algae growth on the walls of the sewage line is responsible for the low carbon dioxide values. Also, it was reported that the production of hydrogen sulphide gas is predictable, as it is not directly related to the concentration of microorganism in the sewage chamber. This research gives an eye-opener on biogas wastage in developing countries

Unlike developing countries, advanced economies combine top-down and bottom-up approach for strategic planning and consider energy policy in the wider scope of spatial planning. In order to better align planning policies in different sectors, the authorities have transferred decision making from the central government to the local communities. This paper provides a brief overview of the London’s strategic spatial and energy policies, examining how they fit within more general visions and objectives. Past and future approaches to the spatial and energy planning were also analysed, with respect to the legal documents that supported actions of different government levels. This paper presents decentralised energy planning and supply in London, highlighting the significance of experience and lessons learned in the development of decentralised energy options for developing countries, willing to engage their resources to contribute to a low carbon economy in accordance with their financial and other possibilities.
