Washington State Ferries — Second-Largest Ferry Network — Switching From Diesel To Batteries | CleanTechnica
“Ian Sterling, public information officer for Washington State Ferries, said the move would cut the cost and pollution caused by the current annual consumption of almost 20 million gallons of diesel across a fleet of 22 vessels ferrying 25 million people a year,” Greentech Media reports.
“The government-owned ferry operator’s annual fuel consumption is on par with that of a ‘midsize airline,’ he said, making it the state’s biggest diesel polluter.”
Sterling added that switch to batteries is “not just because the governor said [to do] it.” It makes financial sense. “But even if you’re not an environmentalist, this is a good idea for the taxpayer because we expect it to pay for itself relatively quickly, based on the price of fuel. It saves millions of dollars annually.”
