FRANKFURT, Aug 14 (Reuters) - RWE remains

bullish on the U.S. market, saying the outcome of upcoming

presidential elections would not affect the market's expansion

of clean technologies.

"Regardless of the outcome, I am convinced that the

expansion of renewables there will continue at a fast pace," CEO

Markus Krebber told reporters after presenting first-half

results.

Krebber declined to comment on a recent report saying RWE

was interested in buying a minority stake in U.S. utility

Calpine.
