HOUSTON, Feb 14 (Reuters) - Former U.S. Federal Reserve Chairman Alan Greenspan on Thursday said the U.S. economy is "clearly on the edge" of a recession.

Greenspan said the economy will continue to erode until there is a stabilization of U.S. housing prices.

"We have a long way to go" before housing prices hit a bottom, Greenspan told energy executives at the CERA conference.

High oil prices are dragging on the economy, but the fact that they haven't done more damage shows its resiliency.

"It's a burden now," Greenspan said. He added that it's "quite remarkable" that the U.S. economy is "able to do reasonably well" with oil prices near historic highs.

Crude oil futures hit above $95 a barrel on Thursday and went above $100 in early January.

Greenspan again -- as he had last month -- said that the likelihood of the U.S. economy going into recession was "50 percent or better."
