In this episode of the podcast, I speak to Abraham Cambridge. Abe is the founder and CEO of The Sun Exchange, which is an online solar energy marketplace. In short, the company provides a platform to buy solar panels in the sunniest places on earth. When the panels produce electricity, the owners receive payment in bitcoin. In Abe’s words, the company acts as a market maker between solar panel manufacturers, installers, buyers and customers.

It’s a great model, because the work they do is accelerating the transition to clean energy while also helping communities and businesses access cheap energy – and also providing a good return on investment for the people providing the capital.

The Sun Exchange bypasses the traditional networks of energy and finance using a few innovative new technologies, including bitcoin. And in our conversation, we assume a bit of knowledge about bitcoin. So, if you’re not familiar with it, I can highly recommend doing some reading. I’ve found that learning about bitcoin is actually a great way to learn about the world in general. Because you will touch on topics like history, economics, finance, cryptography, computer science, game theory and psychology.

Here are a couple of resources I’ve found useful for understanding the history and technical aspects of Bitcoin:

* Digital Gold – Nathaniel Popper* The Bitcoin Standard – Saifedean Ammous* The Internet of Money – Andreas Antonopoulos* The following video by 3blue1brown:

* Taylor Pearson has collated more bitcoin resources here* As has Jameson Lopp, here

And finally, more bitcoin resources, as well as links to all the books and websites we mention in the episode, can be found in the show notes below.
