Fraudulent caller. Just receive call from someone claiming to be from the Sustainable Energy Institute and is working with P.G.&E. The S.E.I (http://www.s-e-i.org/index.asp) was organization formed to "improve public awareness and understanding worldwide of the debates over future energy supply and demand options...". It is no longer active (2001-2006). These cats are getting VERY sophisticated, using real entities, local area code phone numbers, spoofing actual P.G.& E. phone numbers. WATCH OUT! Always ask for the name of the company who is calling. Get their information and share it!

They call the house number but never leave a message. We tend not to answer if we don't recognize the number.

Telephone terrorist.
