Hawaii has unveiled plans to be first in the nation to roll out electric car stations statewide — a move the governor hailed as a major step toward weaning the islands off oil. Hawaii imports foreign oil for almost 90 percent of its energy needs. One-third of that oil is used to power cars and buses on island streets. Gov. Linda Lingle said Tuesday the program would help Hawaii meet its goal of slashing fossil fuel use 70 percent by 2030. “This is the preferred future,” Lingle said at a press conference.
