The most sustainable energy is the energy not used. Best way to (not) use energy is the proper design of a facility or an energy consuming system. The remaining energy needs have to be covered with energy utilisation of waste materials, renewable energy sources and, until the previous solutions are not sufficient to satisfy the energy demands, the last is the use of conventional fossil and nuclear energy sources. In terms of renewable energy, biomass has an important role today. However, there is a difference between available inputs and utilisation when considering biomass energy possibilities in rural and urban context. This paper suggests biomass energy possibilities that are recommendable in rural context: possibilities of solid biomass combustion, of liquid biofuels and of anaerobe digestion. Also important are possibilities of solid biomass combustion and wet biomass digestion for urban energy production, although with some remarks on system considerations of urban biomass. Most advanced solutions for sustainable management of biomass energy include circular systems, both in rural and urban context, as recommended.

Energy crisis in Pakistan had been brewing long before it became an important national issue with the potential to significantly affect the outcome of general elections of 2013. The looming crisis of depleting non-renewable energy sources combined with a feeble economy has lent a new urgency to the search for an energy mix which is sustainable, economically viable and environmentally least hazardous. Fossil fuels with their known adverse environmental impacts dominate the current energy mix of Pakistan. The renewable energy sources remain underutilised despite being cost effective and less hazardous for the environment. A substantial amount of literature has highlighted various dimensions of existing energy sources in Pakistan with a particular emphasis on the environmental impact, the sustainability and the efficiency of various energy sources [see Asif (2009); Basir, et al. (2013); Bhutto, et al. (2012); Mirza, et al. (2009, 2008, 2003); Muneer and Asif (2007); Sheikh (2010) for example]. This study analyses the environmental impact, economic feasibility and efficiency of various energy sources subject to various economic and noneconomic constraints. Section 2 discusses energy security by reviewing various tapped and untapped energy sources besides analysing current energy mix and its future prospects. Section 3 highlights the interaction of energy use and environment. Section 4 discusses two approaches to assess the feasibility of an energy mix: disaggregated and aggregated. The latter approach makes a multidimensional comparison of all the energy sources discussed in this study. Section 5 consists of discussion and concluding remarks.

Life Cycle Perspective

The aim of this study is to assess the environmental impact of storage systems integrated with energy plants powered by renewable sources. Stationary storage systems proved to be a valid solution for regulating networks, supporting frequency, and managing peaks in electricity supply and demand. Recently, their coupling with renewable energy sources has been considered a strategic means of exploiting their high potential since it permits them to overcome their intrinsic uncertainty. Therefore, the storage systems integration with distributed generation can improve the performance of the networks and decrease the costs associated with energy production. However, a question remains regarding the overall environmental sustainability of the final energy production. Focusing on electrochemical accumulators, the problems mainly concern the use of heavy metals and/or impacting chemical components of storage at the center of environmental hazard debates. In this paper, an environmental assessment from a life-cycle perspective of the hybrid energy systems powered by fossil and renewable sources located on two non-interconnected minor islands is presented. Existing configurations are compared with new ones obtained with the addition of batteries for the exploitation of renewable energy. The results show that, for batteries, the assembly phase, including raw material extraction, transport, and assembly, accounts for about 40% of the total, while the remaining part is related to end-of-life processes. The reuse and recycling of the materials have a positive effect on overall impacts. The results also show that the overall impact is strongly related to the actual energy mix of the place where batteries are installed, even if it is usually lower than that of the solution without the batteries. The importance of a proper definition of the functional unit in the analysis is also emphasized in this work.

This article deals with use of global energy sources and their environmental impacts. The energy sources have been split into three categories: fossil fuels (oil-coal-natural gas), renewable sources, and nuclear sources. Oil and gas are expected to continue to be important sources of energy. New efficient and cost-effective small-scale renewable energy generation options are commercially available today. The share of renewable energy sources is expected to increase very significantly. Recently, environmental problems resulting from energy production, conversion, and utilization have caused increased public awareness in all sectors of the public, industry, and government in both developed and developing countries. The environmental impact of energy use can be seen in two ways: The utilization of limited natural resources and the stress caused by environmental pollution. To combat that environmental damage, exploring and exploiting the utilization of combustible renewables and waste would be a necessary measure for decreasing the environmental impact of energy use.
