The amount of "Energy use" is now an essential indicator and is closely relevant for climate change problem, because the use of energy brings carbon dioxide emissions. Of course the amount of "carbon dioxide emissions" is also valuable. For considering these indices, we consider these matters by indices such as "per capita" and "per 1$ GDP". Using the data, we make vector field of two indexes on the scatter diagram. This idea makes two points of support for understanding the data, one is visual support and the other is support for constructing mathematical models. For constructing the vector field, we apply Kernel density estimation and Geographically Weighted Regression. We show vector fields of energy use and carbon emissions, and using our diagram, we examine of the global flow of indexes. Moreover, we discuss the method and the result of forecast amounts of indexes using the vector field. In the result of data analysis, we show vector field of these indices by 120 countries during period of 1990 and 2005. Keywords: Energy Use（エネルギー利用量）, Carbon Emissions（炭素排出量）, Scatter Graph（散布図）, Vector Field（ベクトル場）, Adaptive Spatial Kernel（適合的空間カーネル）
