PSE&G, New Jersey's largest utility, said on Tuesday it would buy hybrid vehicles over the next decade to replace 1,300 vehicles, or nearly one-third of its fleet, Associated Press reports. The utility will invest in hybrid cars and light trucks, hybrid “bucket truck” prototypes, electric-drives and alternative fuels. The effort should reduce the carbon dioxide output of Public Service Electric & Gas by 81,000 tons over the period, the utility said. PSE&G said it will become one of the first U.S. utilities to use hybrid aerial lifts, known as bucket trucks, which allow utility workers to assess and repair power lines. The new hybrid trucks were recently introduced to the market with limited availability, but PSE&G is scheduled to receive two later this year.
