Abstract
Recently, not only in the advanced country but also in the developing country, the energy demand has increased a developing economy. It is impossible to fill all energy demand by a current fossil fuel. And, in the use of the fossil fuel, there is a problem on the environment to exhaust a lot of carbon dioxides which are the one of the factors of global warming. According to such a trend, the renewable energy as the photovoltaic and wind power generation is remarkable. The use of renewable energy is promoted in not only Europe and Japan, but also East Asia. The renewable energy is a regional distributed one, and its generation site is a compact scaled one. The regional distributed energy is produced and consumed in the community, so we need to suggest/consult considering to the characteristics of an individual region. Our geological engineers have grasped the characteristics at region, thus, we will also resolve the renewable energy problem at community.
