To put it into prospective, the Marcellus Shale is 141 TCFG.
96 TCF is like 3 years of current 33.3 TCF per year we burn to the sky
Electric Power ~13.1 Tcf ~40%
Industrial ~10.6 Tcf ~32%
Residential ~4.5 Tcf ~14%
Commercial ~3.3 Tcf ~10%
Transportation & Pipeline Fuel ~1.3 Tcf ~4%
~17 Years Left (Proved Reserves Only): The U.S. Energy Information Administration (EIA) reports that the U.S. has about 583.9 Tcf of dry “proved reserves”. These are deposits already discovered and highly profitable to drill at current market prices and technology
