Newswise — UAB’s Andreas Rauterkus, Ph.D., assistant professor of business who specializes in finance, says if nuclear power is out in Japan, it's going to have to be replaced by something. Rauterkus believes Japan will have to buy more fuel, oil in particular, which will in turn make the cost per barrel increase. Rauterkus can be reached for comment on the potential for gas price increases and other economic effects from the disaster in Japan.
