Tom Konrad is a financial analyst, freelance writer, and policy wonk specializing in renewable energy and energy efficiency. He manages green stock market portfolios, and promotes clean energy by testifying before legislators and regulators on energy policy. He writes articles about investing in clean energy for AltEnergyStocks.com, and about energy policy and economics on CleanEnergyWonk.com. He is a Chartered Financial Analyst (CFA) charterholder, and has a Ph.D. in mathematics from Purdue University, where he wrote his thesis on Complex Dynamics, a branch of chaos theory. His study of chaos theory led to his conviction that knowing the limits of our ability to predict is much more important than predictions themselves, a lesson he applies to both climate science and the financial markets.
