Governor Ed Rendell met with President Bush and other governors this morning in the White House.

The state chiefs talked about ways they can work together to secure a clean energy future for the nation. Rendell says he’s proud that Pennsylvania’s standing out as a green state.

“We are the greenest state in the union in terms of what we do as a state. Our own policies in terms of alternate vehicles, our requirement that all of our state agencies be using 20% green energy by 2010 ranked us number 12th in the union for all institutions and the greenest state in the union. That’s good news,” he told me outside today's meeting.

But the governor also added that the Pennsylvania state legislature needs to pass an energy bill in order to allow the state to be on the cutting edge of conservation. He said he doesn’t think PA can meet the demand for energy without finding new ways to conserve.

Aside from energy, the big chatter at this year’s governor’s meeting was the presidental race. In both parties, several of the leading contenders for the office of vice president are currently governors.

So, it looks like one of the governors might really be heading to the White House. Here are some of the names that are floating around….

On the Republican side Florida’s Charlie Crist has been talked about since he backed McCain before the Florida primary. And Minnesota’s Tim Pawlenty, chair of the National Governor’s Association, will host the Republican convention in his home state. Let’s not also forget Mark Sanford, South Carolina’s governor or Jon Huntsman Jr., the staunch conservative from Utah.

For the Democrats Kathleen Sebelius, governor of Kansas has been mentioned. (If you remember she delivered the Democrats' televised response to President Bush's State of the Union address.) Presidential dropout Bill Richardson of New Mexico is on the list along with Virginia’s Tim Kaine.

While Rendell is a strong supporter of Hillary Clinton he says he won’t be running for Vice President. Instead, we can expect to see him in the governor’s mansion until 2011.
