Degree in physics from Oxford University, MBA from Harvard Business School
Ratings, Awards and Recognition
We cut the carbon dioxide emissions of our 5300sf 1970's house by 43 tons per year getting us to a year round zero-carbon footprint. We are not only saving money, our bills (for heating oil and electricity) are down $11,500 a year, but we are earning a 15% return on our investment. That's 15% after tax and with no volatility. Much better than my stock and bond investments! For more information, check out www.greenzerocarbonhome.com.
