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.

     with  Rule  304 (a) (1)  (iv)  and in  conjunction  with  the  audit of the

     scope or accounting  principles,  but did contain  modifications  as to the

     Form 8-K within two days of receipt by the Registrant.
