Russian energy companies begin to feel pinch as the Ukraine crisis continues and Western nations consider sanctions against Russian energy. If Ukraine's turmoil continues, the Russian economy could lose $115 billion in revenues in 2015.
Russia's Gazprom says there isn't significant risk of disruption of gas to Europe because the Russian gas giant expects to have low seasonal demand. Gazprom CEO Alexei Miller announced that Ukraine would no longer receive more gas starting in June unless it will pay for deliveries in advance.

Western sanctions on Russia over Ukraine have so far avoided targeting Russia's state-owned natural gas company Gazprom. That's largely because Europe relies heavily on Russian natural gas imports and would suffer economically if sanctions are ratcheted up in the Ukraine crisis.
The Ukraine crisis has spurred new interest in Europe finding alternatives to Russian natural gas imports. Spain is not exactly an energy powerhouse, but it could serve as a conduit to the rest of Europe for supplies of non-Russian natural gas.
