- "The solar-power market offers perhaps one of the greatest opportunities among its clean-tech peers. Not only is the worldwide solar market growing by 30% to 50% per year, but the same technologies that enabled the semiconductor and computer revolution are now being leveraged in the solar market." – Ron Pernick and Clint Wilder.

- "Today’s green buildings use some 30% less energy than their comparably sized nongreen counterparts (some save much more), and they’re generally brighter, healthier, and more aesthetically pleasing. Often built with little or no additional up-front cost, green offices, for instance, pay back not only in energy savings but also in greater employee retention, attendance, and productivity." – Ron Pernick and Clint Wilder. The Clean Tech Revolution, 2007, p. 21.
