New York needs more gas.

That’s what experts told Gov. Cuomo yesterday in the wake of Hurricane Sandy, saying a “robust strategic fuel reserve” would help prevent the chaos wrought by fuel shortages in the days after the storm last year.

Cuomo — taking recommendations from disaster- response panels he formed after Sandy — said he was open to the idea, but that the cost and feasibility of creating such a large fuel reserve for gas-guzzling New York remains an obstacle.

“As always in this building, it’s about the cost,” Cuomo said at the Capitol. “We consume a tremendous amount of fuel, so to have a meaningful reserve, you’re not talking about a couple of cans of gas in the garage, you’re talking about a very large undertaking.”

After the hurricane hit, New Yorkers faced massive lines at the few gas stations with power on and fuel to sell — a crisis Cuomo’s panel said could be minimized with fuel reserves and backup generators.

“It’s not just a question of emergency responders getting to where the emergency is,” said Irwin Redlener, director of the National Center for Disaster Preparedness at Columbia University and co-chair of one of the panels. “It also has a lot to do with a functioning supply chain for food, medicine and other supplies.”

Redlener declined to put a ballpark figure on the cost of a reserve.

Among other recommendations were requiring gas stations in key areas to have backup generators and , a geographically-targeted text-messaging system, a central online hub for disaster information and more National Guard training.
