Joel Makower, author of the blog Two Steps Forward, makes an appearance (so to speak) on tonight’s edition of NPR’s Marketplace. The topic? Green energy as the next big thing for investors — and not because it helps out the photogenic megafauna. Check it out.

[editor’s note, by Dave Roberts] Special blog-only breaking news/sneak preview! Makower fans — and who among us doesn’t fit that description? — will be excited to hear that the man himself will soon take up residence as a regular Grist columnist. Ssssshhhh … don’t tell the non-blog-readers.
