Lightning

The perpetually dark skies of Lightning were caused by extreme air pollution, but now the frequent bolts of electricity which hammer down from the sky are harnessed and put to use by innovative power companies. The total power generated in the efficient recycling facilities exceeds 10 million giga-watts. The output is so great, in fact, that Lightning now exports its excess power to neighboring planets. So far, it has only been featured in F-Zero GX.
