Electricity, for instance, is viewed as a connection to the "World", the "English", or "Yankees" (the outside world). The use of electricity also could lead to the use of household appliances, which would complicate the Amish tradition of a simple life, and introduce individualist competition for worldly goods that would be destructive of community. However, in certain Amish groups, electricity can be used in very specific situations. In some groups, for example, electricity can be produced without access to outside power lines.
Twelve-volt batteries are acceptable to these groups. Electric generators can only be used for welding, recharging batteries, and powering milk stirrers. The reasoning behind the twelve-volt system is that it limits what an individual can do with the electricity and acts as a preventive measure against potential abuses. Most twelve-volt power sources cannot generate enough current to power what are viewed as worldly, modern appliances such as televisions or hair dryers. In certain situations, outdoor electrical appliances may be used: lawn mowers (riding and hand-pushed) and string trimmers, for example. Many Amish families have non-electric versions of vital appliances, such as kerosene-powered refrigerators.
