'Polar vortex' cold weather pushes energy costs up

The price of oil rose to near $94 a barrel Tuesday as unusually cold weather in the U.S. was expected to fuel demand in the world's largest market for energy.

By mid-afternoon in Europe, benchmark U.S. oil for February delivery was up 42 cents to $93.85 a barrel in electronic trading on the New York Mercantile Exchange. On Monday, the contract fell 53 cents to settle at $93.43 a barrel.

Crude prices were bolstered by the cold wave in the U.S., the world's top oil consumer, as consumption of heating oil is expected to surge.

Record cold snap

Dangerously cold polar air snapped decades-old records, spreading Tuesday from the Midwest to southern and eastern parts of the U.S. and eastern Canada. Many cities came to a virtual standstill, with flights cancelled and schools and businesses shuttered due to the severe cold.

Forecasters said some 187 million people could feel the effects of the "polar vortex" by the time it spreads across the country.

Prices were also supported by continuing uncertainty about Libya's crude exports. Nearly three years after the start of the civil war that ousted Moammar Gadhafi, strikes and protests in the oil industry and conflicts between the government and regional militias have kept output at a fraction of its earlier level of around 1.5 million barrels a day.

However, even with the uncertainty in Libya, Iraq and other key oil producers, global supplies are expected to remain ample, keeping crude prices under pressure.

"Despite these troubles, the supply outlook is robust," said the Kilduff Report edited by Michael Fitzpatrick. "A test of $92 will likely occur this week, with more losses to follow."

Brent crude, used to set prices for international varieties of crude, was up 47 cents to $107.20 on the ICE Futures exchange in London.
