There's a wide range of folks out there with different motivations and different abilities to fund activities. That's where the challenge comes from. You need to stimulate people to do something.
My particular business is lighting. The LED technology has been truly transformational in our industry. You have energy efficiency gains in the range of 50% to 90% just from introducing the technology.
There are, however, other benefits. We did a school a number of years back into which we introduced dimmable lighting, which comes free with LED technology and fixtures, and the teachers just loved it. As a result, schools in that district followed that standard, just because there was something new that benefited their ability to present material on screens in a classroom.
That's just one example. There are so many innovations possible.
