Finance ministers from the G-20 member nations failed to reach a consensus on how to solve the most immediate problems threatening the global economy, the <i>Wall Street Journal</i> reported. But the influential financial leaders agreed that rising global demand for energy and minerals – which could spark higher inflation – pose the most immediate problems. A paper by the International Energy Agency presented at the meeting said energy demand would grow 50% in the next 25 years. Issues like carbon taxes and greenhouse-gas emission eluded a group solution. Leaders failed to agree on the use of nuclear power to diversify energy consumption and how to reform the World Bank and the International Monetary Fund. The G-20 includes powerful developed and developing economies like the US, Japan, China and India.
