Navi Radjou : Creative problem-solving in the face of extreme limits

Navi Radjou TEDGlobal 2014  (transcript)
Creative problem-solving in the face of extreme limits
Summary
Every year, 5th of June is World Environment Day (WED) thus my teacher gave me a great article to study English.

In the article, the speaker introduces creative ways to solve our energy problems that face extreme limits and I think that the important words are frugal innovation and ingenuity.

Frugal innovation is the ability to create more economic and social value using fewer resource. It means that we have to use our energy resources with more frugality. We can't do what we don't use energies thus frugal innovation is important.
Ingenuity is the quality of being clever, original, and inventive. It means that we have to more think about reducing energy usage and it's needed more ingenuity.
Some areas of the world, even developing countries,  use telemedicine 1),
mobile payments 2) and clean energy 3) instead of building expensive hospitals and banks. However, a lot of areas of the world, especially developed countries use tons of natural resources to create ever more complex products, though, people won't be able to continue buying those because of expensive, will run out of energies, and existing products and services won't be needed by customers soon.

The conclusions that the speaker gave the point of creative problem-solving are simple, same and small. It means that complex functions, new products, and being widely big are needed tons of natural resources. This is the key to Frugal innovation, 3S is named by me, though.
