エネルギー資源の未来像

抄録

To consider the future prospect of energy resources, ultimate resources, technical and economical recoverable resources are reviewed. As the result of comparison between each reserved recoverable resource and consumption, it is suggested that the pattern of present energy consumption is unsuitable for some reserved resources and these unsuitability will increase in future.
Mean yearly maximum energy consumption per capitation is derived from historic trend of annual energy consumption in several developed countries, and it is presumed as 30×10⁶ kcal.
World energy consumption is represented as the product of mean energy consumption per capitation and world population. Thus future prospect of world population is also refered.
From the futiire prospect of world population and economical growth, it is pointed out present reserved economical recoverable resources will be consumed nearly in 2, 040.
For the human being surviving, balancing between energy consumption and reproduction sould be essential. Forestry product as the settler of solar energy will be useful for the renewable energy resource, however world wide management of forest and technology development to use resource economicaly are required.
