Shale gas technology has closed the gap between the energy equivalent between natural gas and coal. Horizontal drilling and fracturing have increased natural gas reserves in the U.S. by as much as 40% which have lead to lower prices (more affordable) and greater less price volatility – a problem that has historically plagued the natural gas industry. Despite the progress by natural gas industry to reposition natural gas as the cleanest fossil fuel domestically available to meet U.S. energy needs, considerable hurdles are yet to be cleared and the coal lobby in the U.S. is well funded and well established.
