Cold weather blasted parts of the U.S. and rendered millions in Texas without power amid the freeze. The weather fostered demand for fuel while simultaneously threatening to hamstring oil production in the state. More than 4.1 million people woke up without power in Texas, according to poweroutage.us., as record low temperatures brought a demand for power that the state's electric grid cannot handle. The areas hardest hit by the outages were around Galveston and Houston.
