Human population has always been advocated to use exosomatic energy, exist in abundance in Mother Nature. As of today world's population has reached to 7.1 billion, which will be exceeding 8.0 billion by 2050. To fulfill the energy demand of increasing population, world existing energy should be increased by >50% by 2050. The question is do we have enough energy resources to meet the future energy demand? Secondly, the use of reserved gas, oil, coal and other carbon-based energy sources would continue to emitgreenhouse gases which are estimated to warm up the world by 2°C by 2020, raising the sea level which will dwindle the world cultivable land. This paradigm shift has called foreffective, sensitive and advanced technologies dealing with the production, harvesting, conversion and distribution of renewable energy to meet the future energy needs. This paper has highlighted the potential applications of carbon nanotube (CNT) based composites to harvest the unlimited solar energy into electrical, mechanical and other forms of useful energy for human benefits. The competitive performances of CNTs in solar cells would build multibillion dollar energy market using green chemistry principles, reducing green house emission and ensuring enough energy for the future generations.

Nepal could rely on its huge renewable energy potentials to meet its energy demand sustainably. Also, renewable energy sources are considered by several national policy makers and international organizations as an engine for socio-economic development of the country, which can provide access to electricity to everybody and stimulate economic activity and economic growth. Several efforts were taken by the national government to stimulate deployment of renewable energy electricity generation capacities. However, the country is still not able to cover its energy needs with renewable energy despite decades of efforts for their deployment. The assumption of this research was that uncertainty in energy policy and planning gaps in Nepal are connected with the dominance of a limited number of discourses and ignorance of other voices which might be helpful. Nowadays, evidence exists that a multi-stakeholder and multi-sector perspective is extremely important for sustainable development. We provide evaluation of various perspectives, including technical, social, economic, environmental, and political. We collect empirical data in frames of a comprehensive stakeholders’ process in Nepal. The stakeholders’ preferences are analyzed through various methods of decision support sciences such as multi criteria decision analysis. To fast track hydropower development, the government has classified them into five categories based on their generation capacity. Assessment of each category and their collective comparison on multiperspectives has never been tried. Hence, such an assessment leading towards their prioritization is the objective of the study. It may help to identify a suitable strategy or policy to maximize national benefits. The study carried within the framework of five alternatives (categories) of hydropower schemes and nine different hydropower perspectives applicable in Nepalese context. The scoring method based is on secondary source evidence is applied for assessment. The study ranks medium schemes (25 to 100 MW) as best in Nepalese context.

Energy is considered as a key source for the future and plays a pivotal role in its socioeconomic development by raising the standard of living and the quality of life, not only for India but also for the world. In view of the scarce fossil fuel reserves, solar energy is one of the important sources of renewable energy used in India because of the suitable climate conditions. It receives about 5485.17 Wh/m2day of solar insolation with an annual total of about 19, 74, 661.2 Wh/m2. Except for the monsoon months, solar radiation incidence is very encouraging, from the application point of view. For the efficient functioning and better performance of solar energy device, the information of solar radiation and its components at particular location is very essential for designing the solar energy devices. Therefore, over the years, several empirical correlations have been developed in order to estimate the more appropriate solar radiation in India as well as around the world. Here we present a review of different solar radiation models which predict global solar radiation and discussed the long-term plan to meet future energy demand with renewable energy due to economy growth.

Energy plays a pivotal role in ensuring economic growth, social equity and live-able environment. In this regard, the non-renewable or conventional source of energy such as oil, gas and coal continue to supply the energy demand throughout the world. Nevertheless, as the awareness of the international society towards the protection and preservation of the global environment is rapidly growing, the utilization of energy resources has been gradually shifted from the non-renewable to renewable ones. Observing the international developments in the field of energy, further international legal instruments is required to be able to regulate renewable energy activities undertaken by the countries today. Although there have been a number of rules in international law, but until recently, most of these regulations is still not legally binding. Moreover, to achieve world order that uses renewable energy, international law also had to resolve some fundamental issues, namely the issue of state sovereignty and energy security.

Abstract. Increasing the production of clean and environmentally friendly energy has become one of the world agendas as a strategic effort in dealing with long-term climate change. Seeing the potential of the energy produced, the ease in the installation process, with the small risk of harm generated, solar energy has received significant attention from many countries in the world. The potential for solar energy in Indonesia alone reaches 207 GWp, but only 145.81 MWp has been utilized. Currently, the Indonesian government has set a target to build a Solar Power Plant capacity in 2025 of 6.5 GWh. Urban areas are areas with higher energy demand than rural areas, but the availability of vacant land in urban areas is very minimal for installing solar power plants. Therefore, rooftop solar PV(Photovoltaic) can be a solution in dense areas such as cities. Good planning by looking at the potential resources and energy needs in spatial is needed to manage and utilize energy optimally and sustainably in urban areas. This study aims to develop a geospatial assessment for plan smart energy city that uses rooftop solar PV's potential energy in every building that is effective and efficient. The novelty in the analysis of the distribution of the potential for rooftop solar PV development in urban areas integrates meteorological and spatial aspects and socio-economic aspects. Integration of multi-dynamic spatial data uses in determining the rooftop solar PV construction location, such as meteorological data for solar energy potential, increasing energy needs of each building, and socio-economy data. The data source used comes from statistical data and remote sensing data. The analysis will be carried out temporally (2008, 2013, and 2018) to see the pattern of changes in aspects used in a certain period so that the development plan can be carried out more optimally. This research's output is the formation of a priority analysis of solar PV rooftop construction in urban areas, especially the city of Bandung. The result of energy can also produce by the construction of rooftop solar PV in a potential area. This research is expected to be utilized by policymakers to develop renewable energy in the city of Bandung and increase community participation in switching to renewable energy.

The Aluminum Industry

This paper is an ethnographic exploration of the volcanic landscapes of Iceland, where the extraction of geothermal energy for the production of aluminum is triggering anthropogenic earthquakes. As the aluminum industry seeks to decarbonize their industrial infrastructure, they are increasingly looking to renewable energy havens, such as Iceland, to supply their expansive energy needs. While this paper is partly about understanding the forms of politics at stake in decarbonizing modernity’s infrastructures, it is more specifically concerned with the temporal politics of anthropogenic earthquakes in the Hengill volcanic zone in the south west of the country. The paper takes up the perspective of geologists tasked with analyzing the emergence of these new earthquake forms, as well as locals from a small town in the vicinity who are learning to live with them. While focusing on the conflict that has ensued in the wake of earthquake production, the article pays particular attention to the importance of acceleration––both economic and geologic––in their making. This leads to an analysis of how alternate temporal renderings of anthropogenic earthquakes invoke competing claims about the future. Anticipating the future, the paper argues, is a form of temporal politics through which the various actors either legitimize, or protest against, these volcanic interventions.

The Impact

Since the turn of the century, gas has been highlighted as the transition fuel to a lower emissions world, and, in 2011, the International Energy Agency published a special report entitled ‘Are we entering the golden age of gas’, which indicated that gas use could rise by over 50% to provide more than 25% of world energy demand by 2035. Even though gas use has risen in tandem with the increase in renewable energy, over the past decade, coal has been the fastest growing fuel because developing countries choose cheap power to provide their growing energy needs. Gas has been, and continues to be, subject to a green, cheap squeeze; squeezed by cleaner renewables on the one hand, and cheaper coal on the other. This paper will look at the impact that increasing amounts of renewable energy has on existing power generation and supply systems, and provide insights into the potential range of outcomes in emission levels, and the need to not only discuss renewable energy target, but to also understand the total energy mix, and the need to reposition gas from a transition fuel to the natural long-term companion of renewables.

Since the emergence of the industrial revolution, the use of energy resources has increased considerably, particularly non renewable (coal, oil and gas), so these resources are no longer sufficient to cover the different energy needs, and this has become a challenge to the energy independance of many gouvernment now and in the future. This has caused the world to scramble for other ways to satisfy these needs in which the results of scientific research and development envolved from alternative uses of old energy sources and named green economy, and many think about the future of energy despite the barriers that still hinder the general application of this type of economy. Energy consumption in Algeria is focused almost entirely on fossil fuels, hydrocarbons, and gas in particular. In recent years, Algeria is deciding to move intro the green economy, the unique solution for meeting future energy requirements and helping reduce environmental risks.

Energy demand continues to grow with the world’s burgeoning population. Meeting energy needs through renewable sources allows for market growth with limited environmental impact, but sourcing constraints can limit production, creating industrial and environmental problems. The exploitation of end-of-use and end-of-life photovoltaic (PV) options that are traditionally treated as waste offers a valuable opportunity to support renewable energy market growth with fewer sourcing constraints and minimal environmental impacts, but this circular investment has not yet been broadly implemented, nor is broad guidance widely available to aid its implementation. From a business perspective, this paper discusses the technical issues, assesses the anticipated market growth issues, and proposes a combination of circular economy, industrial ecology, and process integration principles to contribute a theoretically supported, practical framework to improve the management of end-of-use/life PV products and support renewable energy market growth.
