For Immediate Release Austin, Texas — (Business Wire) February 14, 2008 — Sustainable Energy Development, Inc. (Pink Sheets: SEGV.PK) (the “Company”) is pleased to announce that Alex Tawse has been appointed as the Company’s President & Chief Executive Officer effective immediately. Mr. Tawse’s responsibilities include running the Company on a day–to-day basis and furthering growth through acquisition.

The Company aims to provide new technology to the domestic oil and gas industry as well as acquire profitable existing independent oil and gas drilling and service companies. It will develop portable, flexible drilling technologies that will allow service delivery to previously inaccessible areas as well as provide technology options to customers who desire a smaller ecological footprint during the drilling process. Mr. Tawse has focused his latest efforts on identifying a potentially lucrative merger candidate.  This candidate has a particularly useful patent pending that supports the new direction of the Company.  In order to effectuate this merger, the Board is considering a reverse split.  The Board believes that the merger and reverse split are necessary stepping-stones towards an upgrade of listing status to Over the Counter Bulletin Board (OTCBB).

Commenting on his appointment, Mr. Tawse stated: "Being appointed President and CEO is a great honor, however, it means little unless we focus on returning value to our shareholders.  The Company has given me full authority to find new sources of capital, bring in talented employees, and close deals on merger candidates that will improve overall company value.  I appreciate the continued support from all of our shareholders moving forward during this period of transition."
