Justin Hall- Tipping: Freeing energy from the grid

I think that Justin Hall's ideas are pretty interesting he is saying basically that there should be a way to use our energy without harming our environment, and that there should be a way to conserve water, He made good points to back up his statements like the little child who died of thirst, plus he showed infrared devices that would allow us to save the energy that everybody in the world has to live with. If we don't start doing something about these two problems then we are going to run out of water and are not going to have any sort of energy.
