Look at this giant LED display, all of those LEDs are using sun energy which is gathered each day. You can find this giant LED all near the site of the 2008 Olympic Games, the Xicui entertainment complex in Beijing, China.
They plan to turn on and go live this month, it will display various video of installations and performances by various artists. Hopefully the sun keeps shining during that day, otherwise, won’t be able to see any performances.
