ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

(i)  On October 15, 2001 Onsite Energy  Corporation (the  "Registrant")  engaged
     the accounting firm of Swenson Advisors, LLP, as its independent certifying
     accountants  for the  remainder  of the fiscal year  ending June 30,  2002,
     including  preparation of the audit and 10-K for the fiscal year ended June
     30, 2002.

(ii) On October 15, 2001, the Registrant notified Hein + Associates LLP of their
     dismissal.  Hein + Associates LLP was the independent certifying accountant
     previously engaged to audit the Registrant's  financial  statements for the
     period ended June 30, 2001.

(iii)The Registrant's  engagement of Swenson Advisors, LLP, and the dismissal of
     Hein + Associates LLP were recommended by the Registrant's  Audit Committee
     and approved by the Registrant's Board of Directors.

(iv) During the two fiscal  years ended June 30, 2000,  and June 30,  2001,  and
     through the  subsequent  interim period ended October 15, 2001, to the best
     of the  Registrant's  knowledge,  there were no  disagreements  with Hein +
     Associates  LLP  on any  matter  of  accounting  principles  or  practices,
     financial  statement  disclosure  or  auditing  scope or  procedure,  which
     disagreements  if not resolved to the satisfaction of Hein + Associates LLP
     would have caused that firm to make reference in connection with its report
     on the financial statements of the Registrant for such years.

(v)  During the two fiscal  years ended June 30, 2000,  and June 30,  2001,  and
     through the subsequent interim period ended October 15, 2001, in accordance
     with  Rule  304 (a) (1)  (iv)  and in  conjunction  with  the  audit of the
     Registrant's  financial statements for the fiscal years ended June 30, 2000
     and 2001, there were no reportable events.

(vi) The Registrant has authorized Hein + Associates LLP to respond fully to all
     inquiries of Swenson Advisors, LLP.

     Hein + Associates LLP reports on the financial statements as of and for the
     years ended June 30, 2000, and June 30, 2001, contained no adverse opinions
     or  disclaimers  of opinion and were not  modified or qualified as to audit
     scope or accounting  principles,  but did contain  modifications  as to the
     Registrant's ability to continue as a going concern.

(vii)The  Registrant  requested  that Hein + Associates  LLP furnish a letter to
     the Registrant  addressed to the Securities and Exchange Commission stating
     whether  it agrees  with the above  statements.  If Hein +  Associates  LLP
     chooses  to send such a letter,  it will be filed as an  amendment  to this
     Form 8-K within two days of receipt by the Registrant.
