Why is Sarah Palin conisdered an expert on energy?

So, normally, when I hear someone in the media say something more than once, I assume it's a lie. That might be cynical, but it's worked well. And John McCain's called Sarah Palin an expert on energy more than once. It's nice to validate one's heuristics every now and then, so I decided to look for evidence that Governor Palin was an expert on energy. On her bio page at Senator McCain's campaign web site, I found

She created Alaska’s Petroleum Systems Integrity Office to oversee and maintain oil and gas equipment, facilities and infrastructure, and the Climate Change Subcabinet to prepare a climate change strategy for Alaska.
...
Governor Palin took on the oil companies and began a competitive process to construct a gas pipeline. Because of her leadership, work has begun on a $40 billion natural gas pipeline – the largest private-sector infrastructure project in North American history – to help lead our country to energy independence.

When oil and gas prices went up dramatically and the state revenues rose, Governor Palin sent a large share of that revenue directly back to the people of Alaska. She also suspended the state's fuel tax.
...
As Governor, Palin is chair of the Interstate Oil and Gas Compact Commission, a multi-state government agency that promotes the conservation and efficient recovery of domestic oil and natural gas resources while protecting health, safety and the environment. She also serves as chair of the National Governors Association (NGA) Natural Resources Committee, which is charged with pursuing legislation to ensure state needs are considered as federal policy is formulated in the areas of agriculture, energy, environmental protection and natural resource management.
...
She also served as chair and ethics commissioner of the Alaska Conservation Commission, which regulates Alaska's most valuable non-renewable resources: oil and gas. When she found corruption there, she fought it and brought the offenders to account, even though they may have been members of her own party.

I expected the least critical possible analysis of Governor Palin's background on the site, so I'm not going to criticize this. But, where's the policy expertise? She has some background in pipeline planning maybe, but energy generally? Isn't Senator McCain supposed to be Mr. Nuke? That doesn't even involve oil and gas pipelines.
