article, generating electricity by burning natural gas is cheaper than burning coal if the price of gas remains below US or about $3 per 1000 cubic feet. Also in 2013, Ken Medlock, Senior Director of the Baker Institute's Center for Energy Studies, researched US shale gas break-even prices. "Some wells are profitable at $2.65 per thousand cubic feet, others need $8.10…the median is $4.85," Medlock said. Energy consultant Euan Mearns estimates that, for the US, "minimum costs [are] in the range $4 to $6 / mcf. [per 1000 cubic feet or million BTU]."Conversions "$ per MM [million] Btu multiplied by 1.025 = $ per Mcf" See also Unconventional (oil & gas) reservoir Biogas Oil sands Peak oil Tight gas Fracking Underground coal gasification References Further reading Gamper-Rabindran, Shanti, ed.
