EXHIBIT 99.1

December 9, 2008
Dear AE Biofuels Shareholders,
As we approach year-end, I would like to give a brief update on the status of AE Biofuels, Inc. (the Company) and its subsidiaries, as well as highlight some of the key projects planned for 2009.
In 2006 and 2007, the Company raised approximately $34 million in equity to fund its business plan.  In 2008, the Company made substantial progress in executing against its plans, highlighted by the following events:
India
· We completed our first biodiesel plant in Kakinada, India, which has a nameplate capacity of 50 million gallons per year (MGY). We plan to expand our biodiesel capacity at this plant to 100 MGY in 2009.
· In October we received our factory license to produce and sell biodiesel for both domestic use and for export internationally and we commenced sales in November 2008.
· We have recently signed an agreement to provide the Kakinada plant with a working capital line of credit, which will fund plant operations at full capacity.
· In addition, the Company is also negotiating additional biodiesel sales at favorable profit margins.	The Company’s biodiesel production facility in Kakinada, India.
· In October, the Company appointed Sanjeev Gupta as President of our Indian subsidiary.  A two-year member of the AE Biofuels team, Mr. Gupta is a former Nabisco executive in India and recently served as the president of a $250 million global specialty chemicals supplier.
· Glycerin is the primary byproduct of biodiesel production.  We are in the process of constructing a glycerin refinery and pre-treatment facility at our plant in Kakinada, which we expect to complete in the first quarter of 2009.  This refinery will enable our plant to sell refined glycerin at a significantly higher price than crude glycerin and is expected to provide additional positive cash flow from the Kakinada facility.

United States
· The 2007 Energy Security Act mandates 100 million gallons of cellulosic ethanol in 2010, growing to 16 billion gallons by 2022.  In August 2008, we opened the first integrated cellulose and starch ethanol commercial demonstration facility in the United States. Our 9,000 square foot demonstration plant is capable of producing ethanol from a variety of feedstock sources, including grasses, wheat straw, corn, corn stover (corn stalks), and bagasse (sugar cane stalks). Our integrated technology addresses the immediate need for commercially viable uses of non-food feedstocks to complement existing sources to meet the worldwide demand for ethanol as a transportation fuel.
· Our strategy for the commercialization of our integrated cellulose and starch process includes: (i) acquiring existing starch (corn) plants and retrofitting them with our technology; (ii) establishing joint ventures with existing ethanol plants (including corn ethanol plants in the U.S. and sugarcane ethanol plants in Brazil and India); (iii) constructing and operating standalone cellulosic ethanol facilities; and (iv) licensing our proprietary technology to ethanol plants in the U.S., Brazil and India.

In October 2008, we negotiated the terms for the acquisition of the profitable operating ethanol production and distribution businesses of Renova Energy plc, a London-based public company previously listed on the AIM Exchange which filed for Chapter 11 on June 30, 2008.  This acquisition, which is expected to close in the first calendar quarter of 2009, will give AE Biofuels an operating 10 MGY ethanol production facility and fifteen ethanol production distribution terminals generating revenues at an annual run rate of approximately $70 million.  At closing, AE Biofuels expects to acquire 72.5% of the equity ownership in Renova’s operating businesses and expects to receive a five-year option to purchase the remaining 27.5% of the equity ownership for $3 million.  The acquisition is scheduled to be funded by up to $31 million of debt provided by current and new lenders.  We plan to convert the Renova ethanol production facility into an integrated cellulose/starch ethanol plant as a demonstration of profitable cellulosic ethanol production at commercial volumes. This transaction is subject to bankruptcy court approval and completion of financing by AE Biofuels.
