Why is it a photovoltaic generation now?
“Photovoltaic generation” that can be introduced even by “Love and earth Expo”. It is said, “Earth friendly electric power”. However, why will photovoltaic generation now?What feature do you exist?
In the global warming conference, Japan is aiming at six-percent reduction of carbon dioxide (compared with 1990) by 2010. However, industry, the public welfare, and it transports it in Japan ･･･ The energy consumed in each field keeps increasing every year. Then, a fundamental review of the energy resource is done with the reduction in the consumption energy ,in a word, conservation of energy between rapids now. Then, being paid attention is a photovoltaic generation. 0 when exhaust of carbon dioxide that is one of factors of global warming for photovoltaic generation generates electricity. It is exactly ideal [kuri-nenerugi-]. Carbon dioxide is exhausted by a chemical, young consumption such as oil. For instance, oil accounts for 52.4 percent in Japan according to comprehensive energy statistics in fiscal year 1998. Coal is 16.4 percent, the natural gas is 12.3 percent, and primitive power is 13.7 percent. In addition, water power and the terrestrial heat are 4.1 percent.
In the current state of such chemical fuel dependence of Japan, environmental problems such as carbon dioxide alone are not problems. It has misgivings about the dryness of natural resources including oil in the near future. When the acceptable [to] years of the energy resource are long, the forecast coal is estimated to be 212 years by ..uranium.. 64 years of 62 ..natural gas.. years of 43 years oil. “Sunlight” that is the energy source of the respect and the photovoltaic generation is infinities.
The conversion to the photovoltaic generation is immediately urged only now though the problem of cost when introducing it still remains.
