How solar energy got so cheap, and why it's not everywhere (yet)

A lot speaks for solar energy. It's clean, renewable – and now even cheaper than energy from fossil fuels like coal or natural gas. Sounds pretty great, right? But it only makes up a tiny bit of global electricity production. Why don't we use a lot more of it yet?

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.
