"Japan's LNG imports soared 11.2 percent to a record high of 87.31 million tonnes in 2012, driven by an increased need for fuel to generate electricity after the
nuclear sector was hit by the Fukushima crisis, government data showed on Thursday."
"Japan paid a record price for crude at $114.90 per barrel last year, compared with $108.65 in 2011."
This goes to what you were saying. There may be alternative energy sources for some countries, but for some, the only way to go is nuclear. Japan is indeed trying to restart most (they've restarted 2) of their reactors, despite the intense protest against doing so. But their fuel costs have caused them to go from a net exporter country to a net importer country. And now they are screwed.
Even if they're increasing LNG, they're still burning coal and oil. All of these pollute, and the dirtier they are, the more people they kill, more than thousands per year. Nuclear kills no one, probably because we are so paranoid about it.
