Low-iemperature Ti02 film fabrication based on an understanding of tne electron transpor1 will also open up the possibility for further reduction in production costs. Study of the environmental aspects of dye-sensitized solar ceds revealed that DSC is a suitaole alternative for the electric generator because of its earth-friendliness.105) Based on a Life Cycle Assessment in ISO 14040 standard, carbon dioxiae emission of the cell is estimated to be 19-47 g C02/kWh, whicn is 1/10 that of the gas power plant (450 g C02/kWh). " oxicity of Dye 3 is negligible because of its negative Ames test.106 ... 

The environmental aspects of coal combustion have been a major factor in the various processes, and the movement of the fossil fuel base away from petroleum and natural gas to coal has increased the need for effluent/pollutant control for large, fossil-fueled power plants (Argonne, 1990). Very large amounts of coal are consumed in generating electricity and the emissions from power stations and similar industrial sources represent a potential, and considerable, environmental hazard. These power plants and the accompanying flue gas desulfurization processes emit effluents, which often are pollutants, and which by mere contact with the external environment or by (generally) simple atmospheric chemical transformations, may form secondary pollutants that are more harmful than the initial effluent/pollutant.
