{{main|Engine-generator}}
An ''engine-generator'' is the combination of an electrical generator and an [[engine]] ([[wikt:prime mover|prime mover]]) mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used, and there are even hybrid diesel-gas units, called dual-fuel units. Many different versions of engine-generators are available – ranging from very small portable [[petrol]] powered sets to large turbine installations. The primary advantage of engine-generators is the ability to independently supply electricity, allowing the units to serve as backup power sources.<ref>{{cite web|url=http://www.wpowerproducts.com/blog/hurricane-preparedness-protection-provided-by-power-generators |title=Hurricane Preparedness: Protection Provided by Power Generators &#124; Power On with Mark Lum |publisher=Wpowerproducts.com |date=10 May 2011 |access-date=2012-08-24}}</ref>
