Quotes:
Now a recent paper published May 24 in the Astrophysical Journal
postulates that if advanced extraterrestrial civilizations exist, one
reason they might be hard to detect with telescopes from our vantage
point is because their energy requirements may be relatively modest.
If their culture, technology, and population size do not need vast
amounts of power, they would not be required to build enormous
stellar-energy harvesting structures that could be detected by current
or proposed telescopes.

"Large-scale stellar-energy harvesting structures may especially be
obsolete when considering technological advances," adds Vincent
Kofman, a co-author of the paper at NASA Goddard and American
University, Washington, D.C. "Surely a society that can place enormous
structures in space would be able to access nuclear fusion or other
space-efficient methods of generating power."
