History of Coal in America. North American Indians used coal long before the first settlers arrived in the New World. Hopi Indians, who lived in what is now Arizona, used coal to bake the pottery they made from clay. European settlers discovered coal in North America during the first half of the 1600s.
Electrical outlets in The Islands Of The Bahamas are 60 cycles/120 volts, which is compatible with all US appliances. British and European appliances require a flat two-pin adaptor and 220-volt converter.
The United States is one of the few countries still operating on 120 VAC outlets. Many countries in the European Union have switched to 240 VAC for their standard outlets. Some countries use less; Japan makes use of 100 VAC outlets.
