        Know all by these presents, that the undersigned hereby constitutes and
appoints Timothy J. Neumann or Anne V. Vaughan, signing singly, the
undersigned's true and lawful attorney-in-fact to:

        1.  execute for and on behalf of the undersigned, in the undersigned's
            capacity as a director of Cheniere Energy, Inc. (the "Company"),
            Forms ID 3, 4 and 5, pursuant to Section 16(a) of the Securities
            Exchange Act of 1934 and the rules thereunder, and Form 144,
            pursuant to Rule 144 under the Securities Act of 1933 and the rules
            thereunder, if required; and

        2.  do and perform any and all acts for and on behalf of the undersigned
            which may be necessary or desirable to complete and execute any such
            Form 3, Form 4, Form 5 or Form 144 and timely file such form with
            the United States Securities and Exchange Commission and any stock
            exchange or similar authority; and

        3.  take any other action of any type whatsoever in connection with the
            foregoing which, in the opinion of such attorney-in-fact, may be of
            benefit to, in the best interest of, or legally required by, the
            undersigned, it being understood that the documents executed by such
            attorney-in-fact on behalf of the undersigned pursuant to this Power
            of Attorney shall be in such form and shall contain such terms and
            conditions as such attorney-in-fact may approve in such
            attorney-in-fact's discretion.

        The undersigned hereby grants such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact shall lawfully do
or cause to be done by virtue of this power of attorney and the rights and
powers herein granted. The undersigned acknowledges that the foregoing
attorney-in-fact, in serving in such capacity at the request of the undersigned,
is not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16(a) of the Securities Exchange Act of
1934 or Rule 144 of the Securities Act of 1933.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer an officer of the Company unless earlier revoked by the
undersigned in a signed writing delivered to the foregoing attorneys-in-fact;
provided, however, this Power of Attorney will expire immediately upon the
termination of employment or consulting arrangement of any attorney-in-fact as
to that attorney-in-fact only, but not as to any other appointed
attorney-in-fact hereunder.

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of this 2nd day of August, 2010.

                                        /s/ G. A. Botta
