Whoever said that “it’s not easy being green”, must have known what he or she was talking about. Of course, science has made some remarkable progress over the last decade when it comes to clean energy, but how many of those developed clean energy models have actually been integrated within the architecture of our homes and offices? (Power sockets excluded.).

We can hear you think, that stationing a big eco-friendly power plant on your rooftop would perhaps be a little too much, but somewhere in the nearby future you could consider to let nature take over the office building you work in!

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
