I think it's a phenomenon that is not isolated to renewable energy but to environmental products generally. It's very difficult to ask people to pay a premium for a social good, but I believe you have to start somewhere.
There is a meaningful percentage of people who are prepared to do it today. If you roll the clock forward for 10 or 20 years, I think it will become increasingly the norm to make environmental decisions. I think what you're seeing is just the early phases of a curve that will continue to grow.
