LAS VEGAS (Reuters) - Senate Majority Leader Harry Reid on Tuesday said the Senate would return for a "mopping up" session after the November election, and that he hoped to find support for a national renewable energy standard by year end.

Reid, speaking at an alternative energy conference he hosts annually in Las Vegas, also said he had at least one Republican senator ready to vote for a small business jobs bill when Congress returns to work next week.

Democrats have been focused on freeing up credit and giving tax breaks to small businesses in a $30 billion plan which tops Reid's agenda.

"This is not just pie in the sky. I've got commitments from at least one Republican to support us on this. This will be good," he told reporters.

"And remember, we still are going to be in Congress, working, after the election. I've committed to a lame duck. There are things that we have to do. There is a lot of mopping up to do when we come back after the election," he said.

Still, passing any major legislation this year may be difficult with Republicans eyeing gains in the elections.

Speakers at the renewable energy conference bemoaned the lack of national energy policy, and some in particular called for a renewable energy standard that would force utilities to get a portion of their energy supplies from sources like solar and wind.

The measure was not included in the pared-down energy bill Reid introduced in late July.

"In this energy situation I need to get a handful of Republicans, and I haven't been able to do that. I hope that we can do that before the end of the year," he said.
