FORTUNE — Last May, 60 Minutes correspondent Lesley Stahl ran into venture capitalist Vinod Khosla at the D11 Conference in Southern California. During a brief conversation on the lawn, they discussed how clean technology is at a crossroads due to a variety of factors (political gridlock, VC-backed busts, rock-bottom natural gas prices, etc.). So when Stahl decided to pursue the story, Khosla was one of the first people her producer contacted.
Khosla agreed to be interviewed, and also to let 60 Minutes film at two portfolio companies: KiOR (KIOR), a struggling biofuels company whose footage made the final cut; and View, a promising maker of electronically-tinting glass for commercial buildings (it just raised another $100 million), whose footage was left on the editing room floor.
The decision to highlight KiOR and ignore View was in keeping with the piece’s revised focus. No longer was cleantech as a “crossroads” — a phrase used by the 60 Minutes producer in an earlier email to Khosla. Instead, it was about the cleantech “crash.”
As one might imagine, Khosla took exception to the final product. Not so much about being misled, but rather about what he considered to be numerous errors in Stahl’s reporting. Some of the mistakes were about his own activities, including how much he had personally invested in the cleantech space. Some were about how much U.S. taxpayers had lost from Department of Energy loan and grant programs.
Last Friday he sent a lengthy email to Stahl and others at CBS, arguing that the program misrepresented both his own activities and the broader cleantech sector. He also is releasing an open letter to CBS (CBS), which we are publishing below:
CBS News has not yet returned a request for comment from Fortune.
UPDATE: A CBS News spokesman has provided the following comment: “While we respect Mr. Khosla’s view, we are not in agreement with the points he makes about our story, which we began and ended with him and devoted much of to his ideas and to one of the companies he backs.”
