This discusses why solar energy film will be very useful in the comming years. This film is more efficent. Also new testing are being done to put solar film on roofs.
Solar Energy is already being harnessed in many part of the world and it has the potential to provide several times the current world energy consumption if properly exploited.

It's neat to see a multi-disciplinary firm working toward a focused, yet multi-faceted, goal. As a landscape architecture major, this is a field that I could see myself pursuing.
