Natural gas was the origin of the crisis in Ukraine. It is in Russia’s interest to keep Ukraine and Europe hooked on Russian gas at prices just low enough to quash incentives to drill and frack for shale gas. Russia’s state-run news and propaganda outlets have for years disseminated articles critical of fracking and supported opponents of the technique. Now with Yanukovich gone it’s as if Putin has taken the Crimea as a kind of hostage — collateral to hold against what Ukraine owes Russia for gas. The desperation of Putin’s actions underscore the threat that shale gas development really does pose to Russia’s gas-fueled diplomacy. --Christopher Helman, Forbes, 4 March 2014
