GRE companies purchase electricity and natural gas in the wholesale markets which it resells to residential and small business customers in New York, New Jersey, New Hampshire, Pennsylvania, Connecticut, Ohio, Rhode Island, Illinois, Massachusetts, Maine, Delaware, Texas, Maryland, and Washington, DC.

[13][14][15] In February 2013, Israeli authorities awarded Afek Oil and Gas an exclusive 36-month petroleum exploration license to a 153-square-mile (400 km2) plot in the Israeli-occupied Golan Heights, which the UN recognizes to be Syrian territory.

[16][17][18][19] Afek subsequently conducted above-ground geophysical tests and based on its preliminary analysis, has applied for a ten well exploratory drilling program.

[20] South of Katzrin in the southern Golan Heights in 2015, Afek discovered a substantial amount of oil and natural gas reserves which would make Israel energy self-sufficient.

[a][21][22][23] The company had drilled a series of exploratory wells including Ness-5, just northwest of the Avnei Eitan and Nov moshavim and south of Kibbutz Natur and the town of Katzrin; Ness-3, near the Bnei Yehuda industrial area; Ness-6, located near the entrance of Moshav Kanaf, just southeast of Gamla;[24] and Ness 10 north of the Sheikh-Ali Fault.

In November 2017, the company announced that it suspended its exploratory drilling program as the well's target zone does not contain commercially producible quantities of oil or natural gas.

[29] The lease comprised a tract of 160 acres (65 ha), and was granted for an initial term of 10 years with the possibility of up to a 5-year extension upon proof of diligent progress toward commercial production.

In July 2011, the company received a one-year extension of a three-year license to explore oil shale resources on 238 square kilometres (92 sq mi) in Israel's Shefela region.

[33] By the time of the committee ruling most of the staff of IEI, including Chief Scientist Harold Vinegar, had moved to work at the sister company, Afek.

Residents of the local community of Adullam and their supporters led the campaign to stop the IEI work, citing both the environmental damage and the questionable economic value of the project.
