Leonardo DiCaprio's National Geographic documentary Before The Flood premiered two days ago and in case you missed it, you can watch it for free on YouTube.
The entire documentary talks about the fossil fuel industry and the effect it has on our planet, explains the devastating consequences, and tries to find a solution for inevitable climate change, who's effects we are already witnessing.
Elon Musk appears in the documentary (he also appeared in Racing Extinction, which you should watch if you haven't already) and leads DiCaprio trough Tesla's Gigafactory in Nevada.
Musk explains that the Gigafactory isn't built just to manufacture lithium-ion batteries, but he hopes is will serve as a template for how others could contribute to converting the world to clean energy.
It's no news that Musk's companies are working on exactly that. With Tesla Motors and SolarCity, he is already making huge changes in the world and even more important, he's setting an example.
Musk explained that the batteries are the future.
Batteries are critical to a sustainable energy future. The advantage of solar and batteries is that you can avoid building electricity plants at all, so you can be a remote village and have solar panels that charge a batter pack that supplies power to the whole village, without ever having to run thousands of miles of high-voltage cables all over the place.
What's even more interesting, Musk said they did a calculation to see what would it take to transition the entire world to sustainable energy.
We actually did the calculations to figure out what it would take to transition the whole world to sustainable energy. You'd need 100 Gigafactories.
Of course, Musk has no intention of building those factories himself, although we can expect at least another Tesla Gigafactory. But, Musk hopes he will encourage others to follow his path and start building factories that would have a huge impact on the well-being of our planet.
