We can do a lot for the planet by changing how we generate electric power.
But that's not the kind of power Richard Heinberg, fellow of the Post Carbon Institute, writes about in his latest book. Power: Limits and Prospects for Human Survival is about the ways in which people wield power over one another and nature, and more.
The accumulation of power has brought humans to the point where they are capable of ending life on the planet, or most of it, anyway.
Richard Heinberg joins us to flesh out the thinking on power and its use, and how humans might change their ways.
