Paul Gipe

is an author, advocate, and analyst of the renewable energy industry. He has written extensively about the subject for the past four decades, receiving numerous awards for his efforts. Gipe has lectured before groups from Patagonia to Puglia, from Tasmania to Toronto, and from Halifax to Husum. He has spoken to audiences as large as 10,000 and as small as a private presentation for Vice President Al Gore. Gipe is well known for his frank appraisal of the promise and pitfalls of wind energy, including his stinging critiques of Internet wonders and the hustlers and charlatans who promote them. He led the campaign to adapt electricity feed laws to the North American market–the same policy that has stirred a renewable energy revolution in Germany.
