The Clean Tech Revolution: The Next Big Growth and Investment Opportunity, is a 2007 book by Ron Pernick and Clint Wilder. They say that using clean technologies is a profitable enterprise that is moving steadily into mainstream business. Clean technologies are seen to be important for economic growth.

Pernick and Wilder highlight eight major clean technology areas: solar power, wind power, biofuels, green buildings, personal transportation, the smart grid, mobile applications (such as portable fuel cells), and water filtration. Very large corporations such as GE, Toyota and Sharp, and investment firms such as Goldman Sachs are spending billions of dollars on clean technology.
