From the perspective of energy security and environmental sustainability, highly effective uses for fossil fuel in energy industries are demanded. Power plants having integrated gasification combined cycle (IGCC) with advanced configurations are being developed worldwide to use coal and biomass more efficiently and thus cleanly. Gasification forms the major component within the IGCC systems and has the best fuel flexibility of any of the advanced technologies for power production, with the current technology well adapted to use biomass and other low-value feedstock that have high-ash residues (Liu and Niksa, 2004). Gasification also provides an opportunity to control and reduce gaseous pollutant emissions, and a lowest cost approach to concentrate the carbon dioxide at high pressure to facilitate sequestration (Trapp, 2005).

Environmental problems have become more apparent through a continuously growing range of pollutants, hazards, and ecosystem degradation over wider areas. Although the most significant air pollution problems were acid precipitation, stratospheric ozone depletion, and global climate change, the focus has been on global warming due to drastic increase in greenhouse gas emissions and their immediate results through catastrophic climate changes/events.

The conversion of energy is directly related to the pollution in terms of greenhouse gas emission caused by the power plants. The major greenhouse gases like carbon dioxide and carbon monoxide are causing global warming to the environment and hence there is a need to find out alternatives to produce energy in an environmentally benign way. The photovoltaic technology, amongst the others, is one that can be a novel alternative to this problem.

The decline of the world's fossil energy supply, the increase in energy consumption, and the continuous trend of global warming caused by greenhouse gas emissions enforce innovation and research efforts toward the implementation of a global economy based on renewable energy. As mentioned in many sources (e.g., Baneman, 2008), with the increasing price of fossil fuels and augmenting taxes placed by governments on emissions, renewable energies will become progressively competitive.

Energy is a mainstay of an industrial society. It is, therefore, not surprising that many important organizations have attempted to analyze the future need for energy and the availability of various energy sources. Energy consumption growth is closely linked to population growth, although changes in life styles and efficiency improvement have a substantial influence on the per capita annual consumption. The structure of population and the share between urban and rural populations also affect energy demand (Torjman and Shaaban, 1998).

Since historical times mankind is dependent on the use of fossil fuels. The exploitation and use of fossil fuel grew exponentially in the last two centuries when world experienced the industrial development. This period was characterized by extensive combustion of petroleum, natural gas, coal and as a consequence there are produced visible unbalances in the natural environment, especially due to the associated CO2 emissions.

In this paper, the exergy interactions, environmental impact in terms of CO 2 mitigation, and the economics of small-capacity concentrated solar power-driven heat engines for power and heat generation are analysed for residential applications. Starting from a base case study that assumes mass production in Ontario, it is shown that the investment in such a system, making use of a heat engine and having 9m 2 of aperture area, could be about CN$10000 for a peak electrical efficiency of 18% and thermal efficiency of 75%. The average CO 2 mitigation due to combined savings in electricity and heat is ∼0.3kgCO 2kWh -1, a figure 3-4 times larger than for photovoltaic panels. If 25% government subsidy to the investment is provided, the payback period becomes 21.6 years. Additionally, if the financing benefits from a feed-in-tariff program (at 25% electrical sell-back to the grid) and deductions from CO 2 tax are realized, then the payback time drops to 11.3 years. These results are obtained for a conservative scenario of 5.5% annual incremental increase in energy price. For the moderate consideration of all factors, it is shown that within the financial savings over the entire lifecycle, 7% are due to carbon tax, 30% are due to electrical production and the largest amount, 63%, is the result of reducing the natural gas heating capacity with solar heating from the proposed system. © 2011 John Wiley & Sons, Ltd.

Global warming, which is a specific case of global climate change, refers to the increase in the average temperature of the atmosphere and oceans in recent decades, and the projected continuation of this increase. The drivers of climate change are seen as: changes in the atmospheric concentrations of GHGs and aerosols, land cover, and solar radiation (IPCC, 2007). According to the Intergovernmental Panel on Climate Change (IPCC, 2007), most of the increase in global average temperatures since the mid-20th century is linked to the observed increase in the anthropogenic GHG concentrations.

Global warming is considered a problem caused by combined worldwide greenhouse gases (GHG) emissions. Many greenhouse gases occur naturally as a result of Earth's geological, hydrological, and biological cycles. They include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). In addition, other photochemically important gases, such as carbon monoxide (CO), oxides of nitrogen (NOx), and non-methane volatile organic compounds (NMVOCs), while they do not function as greenhouse gas, contribute indirectly to the greenhouse effect (Anonymous, 1998; ICF, 2007).

As the world proceeds into the 21st century, international dimensions of environmental problems have become more apparent and increasingly important. Globalization of the economy, emergence of worldwide communication and information networks, and rapid development of bio- and nanotechnologies all have important consequences for the environment. One may expect that by the middle of this century about 10 billion people will be placing stresses on the world's natural resources which will lead to further environmental problems (Dincer 2003). In fact, future environmental problems arise not only from the exhaustion of natural resources but also from how those resources are consumed. New technologies can and will lessen damaging environmental impacts if they are employed wisely, guided by the market system under some main pillars, such as better efficiency, better cost-effectiveness, better use of energy resources, better environment, better energy security, and better sustainable development.
