Saving energy?

From Kompas

Two years ago when I went abroad I was proud of the Soekarno-
Hatta International Airport. It looked magnificent. During my
stay abroad and after visiting many countries, I still felt that
Soekarno-Hatta airport was wonderful.

But I was disappointed when I returned from overseas after two
years. I didn't find the same magnificent airport. Some parts of
the airport area were poorly lit. Moreover the arrival hall is
separated from the greeting area by a material which is not
transparent as it was before. On the way out of the airport all
lamps along the road were out. What does this mean? Is it for
economical consideration?
