Sustainable Energy Technologies Ltd.: Notice of Insider Options Granted and Other Matters

CALGARY, ALBERTA--(Marketwire - Aug. 14, 2009) - Sustainable Energy Technologies Ltd. (TSX VENTURE:STG) ("Sustainable Energy" or the "Company") announced today that, subject to regulatory approval, it has granted options to its officers and directors to acquire up to 4.3 million shares of the Company. The options, which are generally to be earned as to 1/3 per year, over the next three years, are exercisable at a price of $0.15 per share. Options granted to the CEO are subject to certain performance conditions. The options are granted pursuant to the Company's Stock Option Plan approved at the Annual General and Special Meeting of the Company held July 30, 2009.

The Company also announced that it has retained the services of Renmark Financial Communications Inc. to assist with the Company's investor relations activities at a fee of $7,000 per month. Renmark Financial Communications does not have any interest, directly or indirectly, in Sustainable Energy Technologies or its securities, nor does it have any right or intent to acquire such an interest.

The Company noted that all matters submitted for approval at the Annual and Special General Meeting were approved by more than the requisite majority of the shareholders. These included certain changes to the articles and by-laws arising out of the previously completed private placement and amendment of the terms of warrant issued on the financing to permit such warrants to be exercised for voting common share instead of non-voting common shares.

The Company also noted that former member of the Board, Cliff James did not stand for election as a director of the Company. "Cliff has provided valuable counsel to the Company for many years, often in very difficult circumstances. He has been a good friend of Sustainable Energy and he will be missed." said Michael Carten, Chairman and CEO of the Company.
