Abstract

We are now developing a system to estimate light energy loss to space using the US DMSP data and obtained many interesting results. The satellites have solar synchronous orbits with altitude around 800 km, and continuously obtain absolute flux of terrestrial surface light. City light ejected to space is mostly energy loss because the light is not sued to illuminate objects to be seen or decorated. The total amount of its energy loss in Japan estimated by us is an order of 20 billion yen. We are now estimating its loss for each cities in Japan and in the world. Further, we found a possibility to estimate energy usage of each country after obtaining a clear relation between light energy loss and electric energy usage within different areas of individual electric companies in Japan. Therefore, we would like to conclude that our continuous estimation of city light form space are and will be creating a global information of energy usage.
