It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years. Hydroelectric plants have the advantage of being long-lived and many existing plants have operated for more than 100 years.

Since over half of GE's revenue is derived from financial services, it is arguably a financial company with a manufacturing arm. It is also one of the largest lenders in countries other than the United States, such as Japan. Even though the first wave of conglomerates (such as ITT Corporation, Ling-Temco-Vought, Tenneco, etc.) fell by the wayside by the mid-1980s, in the late 1990s, another wave (consisting of Westinghouse, Tyco, and others) tried and failed to emulate GE's success.[citation needed]
In what decade did ITT Corporation get founded?

The Neolithic 1 (PPNA) period began roughly 10,000 years ago in the Levant. A temple area in southeastern Turkey at Gobekli Tepe dated around 9,500 BC may be regarded as the beginning of the period. This site was developed by nomadic hunter-gatherer tribes, evidenced by the lack of permanent housing in the vicinity and may be the oldest known human-made place of worship. At least seven stone circles, covering 25 acres (10 ha), contain limestone pillars carved with animals, insects, and birds. Stone tools were used by perhaps as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9,500 to 9,000 BCE have been found in Jericho, Israel (notably Ain Mallaha, Nahal Oren, and Kfar HaHoresh), Gilgal in the Jordan Valley, and Byblos, Lebanon. The start of Neolithic 1 overlaps the Tahunian and Heavy Neolithic periods to some degree.[citation needed]
