We need to consider offshore drilling as an alternative to foreign oil, according to U.S. Senator Herb Kohl (D-WI).
However, he says it's not the complete answer to our problems. He says we also need to look at increasing production and explore the expanded use of renewable energy sources. Kohl says it's clear we don't have enough fossil fuels to take care of demand in this country.
Still, the Senator says the U.S. is right to at least have offshore drilling on the table as an option.
Kohl says he's optimistic the nation's dependence on oil will be greatly reduced in the next 10 to 15 years.
