Joseph Romm is a Ph.D in physics from M.I.T. "Dr. Joseph Romm is a leading expert on hydrogen, fuel cells, and advanced transportation technologies."
Here is a link to Joseph Romm's bio. Here is a link to his blog.
Read the bio and you will see a frequent theme: Joseph Romm has made a big career in ideologically motivated activism, has written tons of words (for the environment), has published tons of books and articles.
Has he invented any useful device ? Is he doing any scientific work ? Any tangible, physical gadget? Any real solution ? Has he worked in some team that produced tangible solutions? Has he advanced theoretical knowledge ?
Nope, just public relations and ideological advocacy. (Also government administration jobs). He has produced words, words, words.
Words matter, writing is a respectable profession. But for a scientist, for a Ph.D. holder in physics from M.I.T. this is disappointing. But this is typical of today's "scientists".
The truth is - real scientists, real, ground breaking, scientists and engineers are a very rare breed. Most of the people calling themselves "scientists" and parading impressive titles are nothing of the sort.
(If he has produced something useful besides words I apologize. It wasn't mentioned in his bio.)
