Since the late 1990s, I've covered energy, beginning with the rise and fall of Enron -- first as a magazine writer before becoming a columnist. For more than seven years, I've been a columnist for Forbes while also expanding my coverage to include key environmental issues and emerging technologies such as microgrids. I've also done some global reporting of those same issues that touch the African and Asian regions. My work has appeared in, and by cited by, dozens of publications and broadcasts.
