High energy prices have helped drive innovations in both renewable and non-renewable energy technologies. In this latest edition of Graphic Intelligence, we see the growth in patent applications for these technologies over time (as a share of all patent applications). What this chart suggests is that energy prices can make a big difference in the amount of patents being generated. But it also begs the question; what role can carbon pricing play in developing low-emission technologies? 

To read more about how governments should be implementing low-emission policies, read, A Blueprint for Going Green: The Best Policy Mix for Promoting Low-Emission Technology by David Popp.
