The United States will overtake Saudi Arabia as the world’s leading oil producer by about 2017 and will become a net oil exporter by 2030, according to a report released Monday by the International Energy Agency.

That increased oil production, combined with new US policies to improve energy efficiency, means that the United States will become ‘‘all but self-sufficient’’ in meeting its energy needs in about two decades — a ‘‘dramatic reversal of the trend’’ in most developed countries, the report says.
