Europe: More Coal, Then Less

Europe’s continuing drive toward sustainable energy does not rule out a new generation of coal power plants to replace those scheduled to close by 2015.


Technology Converts Flue Gases to Jet Fuel

A new technology promises major advantages for coal-fired power plants, steel mills, and other industries that produce flue gases—and it could quell concerns about the increased use of arable land and food prices related to the production of ethanol.


Ukraine Looks Beyond Russian Gas

For years, tensions have been brewing between Russia, which provides about a quarter of the natural gas consumed in the European Union (EU), and neighboring Ukraine, a country through which 80% of those exports travel via pipeline.


Will U.S. Natural Gas Inventories Hit Their Caps This Fall?
