There she was, winning Eurovision and taking the crown for Ukraine, back in 2004:
But what has Ruslana been up to since? It turns out that, while she still does the semi-naked dancey shout ostpop, she's now doing it with a political message, campaigning to reduce Ukraine's dependence on natural gas. It's not so much a carbon footprint issue as worries about Putin's control of the gas pipe, naturally.
So far, though, she's doing it all metaphorically:
It triumphs over a synthetic world, dependent on synthetic energy. In the video version, that world is represented by a pale, metallic-looking woman who gets her strength from a giant machine. She's transformed, though, into a kind of Wild Energy woman, reminiscent of Xena the warrior princess.
There's a worry that the issue isn't stimulating enough for young Ukranians; perhaps something a bit more direct might be helpful?
