Study on Emission of Environmental Load in Photovoltaic Power Generation

摘要

Although Japan consumes huge energy, in the ratio which it supply at home among the energy resources which it supply as a primary energy, an energy self-sufficiency rate is only about 5%.This is a remarkable low level as compared with main advanced nations, it is shown that Japan is not blessed with a fossil fuel resource, and the present condition is that the improvement in a self-sufficiency rate has been a subject. And, the correspondence to a global warming issue is called for globally in recent years, and it has been a subject that the amount of excretions of the environmental impact of an energy sector reduces the amount of excretions of the environmental impact especially in an energy sector according to the sector of the amount of excretions of an environmental impact for Japan which occupies most GHGs. Then, its attention is paid to the renewable energy for which the consumption of primary energy utilized the natural energy few. Sunlight energy attracts attention also in it. However, the present condition is that a precise does not evaluate the amount of excretions of the environmental impact of a solar cell. Then, this study is the purpose about evaluating the amount of emission of photovoltaic power generation detailed.
