Genie Energy Ltd.

A maker of retail energy and solar power, Genie Energy resells electricity and natural gas to homes and small businesses under brands like IDT Energy and Residents Energy across roughly 19 U.S. states, while its Genie Renewables arm develops community solar projects and recycled plastic pallets. It grew out of telecom giant IDT Corporation, founded by Howard Jonas, and was spun off as its own company in 2011. Fun fact: its oil-and-gas exploration arm once reported finding a 350-meter-thick rock layer in the Golan Heights, which its geologist called far larger than the average oil discovery worldwide.
