My googlefu fails me..

I recall watching one of the Ted talks on renewable energy. The fellow speaking started with talking about how many solar panels would need to be installed every hour for the next 20 years, wind tubines, etc.. And I think that was just to meet current demand.

Anyway.. I can't find it. Does anyone know anything about this? Either the speaker or a direct link?

I'm sure that when you notice someone has replied to your thread, you're going to think "Oh, someone must have answered my question!". Three days of waiting, and all you get is this. Sad, isn't it?

Thanks BoomerD, but I went through that list. The thing is I'm not sure the entire lecture was about solar energy, I don't recall the main topic. The introduction had mentioned the near impossibility of installing just solar/wind to cover current demand.

Ok.. I started this post about an hour ago... I found it. It's a bit different from what I recall but it's Saul Griffith on Pop!Tech

Massive paraphrasing..
To maintain 450 ppm carbon in the atmosphere (we're in the mid 300 range currently)
- 100 Sq. meters of solar cells per second for the next 25 years.
- 50 sq. meters of mirrors per second for solar/steam power(for 25 years)
- wind.. 1 massive (300 ft.) turbine every 5 minutes.
- Nuclear.. one 3 gigewatt plant per week.
- geothernal, biofuel, on and on.

The entire talk is interesting, but the above comes at the -09:00-ish minute point, for those interested.
