"Green Definition": the first TV resolution that can decrease the energy consumption of your TV. Without downloads, apps or navigating through complicated menus, Green Definition gives to customers the power to save energy just by watching TV.

Green Definition can change the standards of the industry about energy saving solutions, and even change the way we produce entertainment content and advertising. E.g.: adverts about energy conscious cars could be aired only in Green Definition, to reinforce its concept.

To make a content in Green definition, we developed a dotted mesh that turns off half of the pixels from your TV, to be applied directly over content's archives. For consumers, the losses on quality are little: the mesh creates the optical illusion of a slightly less exposed image, that's perfect to be broadcast at night time.

The amount of money needed to air a content in Green Definition is the same amount of money needed to air a content in HD.

The technology is in the final stage of development, ready to be aired in the next few months with consistency.

Green Definition was tested by UL, the most seasoned certification company in the world, and the results were astounding: the technology has the capacity to decrease up to 54% of energy consumption on some TV models.

If every Latin America subscriber of National Geographic watched 1 hour of Green Definition per month, we could save up to 5,4 million KWH. That's enough energy to:

Power the whole country of Congo for 2 days.

Maintain 2043 people for an year.

Run 18 billion of searches on the web.

Keep a led lamp on for over 100.000 years.

and much more.

Content in Green Definition is already been commercialized by Nat Geo, achieving high interested from advertisers and other brands.

And for our consumers, it's a little trade on brightness for a better world. And for a slightly lower electricity bill: 1 hour watched in green definition save enough energy for you to keep a led lamp for 15 hours on your house.

But the most important: with Green Definition, National Geographic's brand philosophy finally can be reflected on one of our most important assets: our channel.

Green Definition is a simple low-cost technology that can change the way content is broadcasted by TV Channels. For the first time ever, National Geographic was able to broadcast a content that can save energy and requires no action from our telespectator to work. Consumers don't need to download an app, or navigate through complicated TV menus: to save energy and contribute to a more sustainable world, all they have to do is watch TV.

Televisions use between 5 and 8 percent of the world's residential electricity. According to SEAD, this amounts to 168 terawatt-hours of electricity use annually, producing 27 megatons of carbon dioxide emissions. And while reducing energy consumption is a on going debate for TV manufacturers, Broadcasters have never entered this discussion.

But for National Geographic, the preservation of Earth and a more sustainable way of life are priority subjects - and this lead to a thought: what could a TV channel do to make its content more environment friendly?

The answer was simple: we needed to turn National Geographic in to the first TV channel that can save energy just by being watched.
