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.

Currently, 80% of global energy is supplied by carbon-based fossil fuels, which has led to concerns over the environmental impact of increasing atmospheric CO2 levels and has sparked ever-growing interest in renewable energy sources.

In The Beginning

Energy transition from a carbon energy driven world to a decarbonized world (H2) is essential for the living for our next generations. Our existing energy source with contents in the beginning (1850) nearly only the element C are used with all their consequences for the burning process and environmental impact. Nowadays the C element in our present energy sources are getting less and less. The environmental impact using fossil energy is huge and with the climate change more and more deadly for the inhabitants on the earth. Producing H2 as a sustainable and renewable energy is only possible using renewable energy sources like PV, Wind, Hydro, Biomass. With today's technology and the constant falling energy prices since the last 20 years H2 is now an alternative secondary energy source for a substitute for fossil sources. Using H2 will give new and unique business advantages. With these business advantages, new and innovative business models can be designed and developed. These novel approaches can be very sensitive to external influences. This destructives situations are making these BM very fragile. Finding ways to stabilize these on a long term without aid from the outside the key for success are new innovative technologies and new innovative BM.

Comprehensive environmental impact assessments of buildings and construction as a whole consider the preparation of construction and finishing materials, their transportation, the process of erecting buildings, long-term operations—including the consumption of electricity, water, and fuels—and the management of the waste generated during the demolition of facilities. In terms of the above-mentioned elements, the most negative environmental impact on a building’s life cycle is in its exploitation stage. In order to reduce this impact, modern sustainable construction uses renewable energy sources. In the area of the Polish building market, analyses of CO2 emissions, the application of LCAs for building materials, and assessments of the social impacts of modern buildings are still very limited. The aim of this study is to evaluate the environmental life cycles and social costs of the CO2 emissions of single-family residential buildings, in which four different systems providing energy (heat and electricity) from renewable and nonrenewable sources are used. In this research, it was found that the annual CO2 emissions per square meter of building surface area in the analyzed objects were in the range of 30 to 176 kg CO2. The greatest contributor to the environmental effects was energy consumption (58% to 90%). The CO2 analysis conducted showed that facilities that use a heat pump are characterized by an environmental effect that is six times lower than that of facilities that are powered by coal combustion and electricity from the network. Similarly, the social costs associated with CO2 emissions were significantly lower in the case of the use of renewable energy sources.
