So in the industrialized world, we built walls that protect us from the externalities of our energy use; we can afford to clean up acute environmental disasters; and we can also afford to adapt to chronic conditions like climate change.

The only way they're going to lift themselves out of energy poverty is by adapting fuels that are more efficient, that are less expensive, that are better for human health, better for the environment and that are more productive.

The prescriptions to solve energy poverty seems pretty straightforward: you develop these technologies that have a great return on investment, and people should be snatching them up.

The first time I ever went down to Haiti was in August of 2008, sort of on a whim, and I was fielding surveys in the rural south of the country to assess the extent of energy poverty.

So I didn't make the sale, but I did learn a really important lesson, which is that technology, products, were not going to end energy poverty.

Specifically, there are two types of access that are going to end energy poverty: there's physical access, and there's financial access.

What we need for ending energy poverty are last-mile retailers that bring these clean energy products to the people.

We all know that clean energy products, technologies, tend to be characterized by higher upfront costs, but very low operating costs.

But you're going to severely diminish the value proposition of your clean energy product if you expect somebody in Haiti to go out, get a microloan, go back to the retailer, and then buy the clean energy product.

So the prescription to end energy poverty is much more complicated than simply products.

We need to redirect cash flows that are going now from the diaspora in the United States through Western Union wire transfers in cash directly into clean energy products that can be delivered to or picked up by their friends or family in Haiti.

We see cities, we see oil fields, you can even make out fishing fleets in the sea, that we are dominating much of our planet, and mostly through the use of energy that we see here at night.

Usually when we think about the atmosphere, we think about climate change and greenhouse gases, and mostly around energy, but it turns out agriculture is one of the biggest emitters of greenhouse gases too.

So more people, eating more stuff, and richer stuff, and of course having an energy crisis at the same time, where we have to replace oil with other energy sources that will ultimately have to include some kinds of biofuels and bio-energy sources.

You heard the discussion about the journey through energy, or the journey through social design, or the journey in the coming and saying, "Why aren't there any women on this platform?"

How? Well according to Einstein's math, if space is uniformly filled with an invisible energy, sort of like a uniform, invisible mist, then the gravity generated by that mist would be repulsive, repulsive gravity, which is just what we need to explain the observations.

When the astronomers worked out how much of this dark energy must be infusing space to account for the cosmic speed up, look at what they found.

So hold the mystery of the dark energy in the back of your mind as I now go on to tell you three key things about string theory.

So particle masses, the strengths of forces, and most importantly, the amount of dark energy would be determined by the shape of the extra dimensions.

So if we knew the shape of the extra dimensions, we should be able to calculate these features, calculate the amount of dark energy.

And this radical proposal has a profound impact on this mystery: the amount of dark energy revealed by the Nobel Prize-winning results.

Because you see, if there are other universes, and if those universes each have, say, a different shape for the extra dimensions, then the physical features of each universe will be different, and in particular, the amount of dark energy in each universe will be different.

Which means that the mystery of explaining the amount of dark energy we've now measured would take on a wholly different character.

In this context, the laws of physics can't explain one number for the dark energy because there isn't just one number, there are many numbers.

It's that the right question to ask is, why do we humans find ourselves in a universe with a particular amount of dark energy we've measured instead of any of the other possibilities that are out there?

Because those universes that have much more dark energy than ours, whenever matter tries to clump into galaxies, the repulsive push of the dark energy is so strong that it blows the clump apart and galaxies don't form.

And in those universes that have much less dark energy, well they collapse back on themselves so quickly that, again, galaxies don't form.

So we find ourselves in a universe with the particular amount of dark energy we've measured simply because our universe has conditions hospitable to our form of life.

The point is, when it comes to universes and the dark energy that they contain, it may also be the right kind of reasoning.

And we find ourselves in one universe instead of another simply because it's only in our universe that the physical features, like the amount of dark energy, are right for our form of life to take hold.
