I don't know about all of them, but at least 3 of those photos are of places on Whidbey Island. (Vol I, II, and IV)

Does electricity work the same way on Whidbey Island as in the rest of the world?

Depends which way the tide is flowing and whether Whidby Island Naval Air Station has paid its electrical bill.

I think electrical polarity is reversed in the Southern Hemisphere due to the Coriolus Effect.

Absolutely, We have to turn the light switch off to get light to work down here. And even then, the light doesn't come "out" of the lamp, it gets sucked into the lamp.
We turn our Televisions upside down to get the right way up picture.

Alan, you need to get a new TV. The new smaller ones (Sharp plasma) have that option on their remotes just for the guys down under.

This sounds like a good place to expand on the dark sucker theory. Lamps really don't emit light they are actually dark suckers rated by the amount of darknes they can suck up. The more dark suckers you place in any given dark area, the less darkness will be maintained. The sun is the ultimate Dark Sucker. LOL.
I think that this theory may have come from down under. The dark side of the world.

It sounds like a black hole to me.

Oh that's right, a black hole sucks up the light.

So, it must be a white hole.

“Black holes do not obliterate information about things which fall into them, but mangle information instead. So says Stephen Hawking, backtracking on his own theory about black holes after 30 years.
The physicist was forced to concede a bet he made with American theoretical physicist John Preskill in 1997 as he unveiled his new theory on Wednesday. Preskill had doubted Hawking's theory that black holes destroy everything that falls into them. Hawking now says information can escape from within them...”
