We at PERC are big fans of Axios energy and climate reporter Amy Harder and her weekly “Harder Line” column. One of her recent stories discussed the need for additional outdoor heaters in restaurants to keep safe outdoor seating available through the upcoming colder months. We were particularly interested in her breakdown of the various options for portable outdoor heating, which of course includes propane. Amy reported some good insights about propane and lower emissions goals, and we couldn’t help ourselves from breaking out our green pen to add in some color commentary. Let’s keep the dialog going, Amy!
