Ruud who invented the electric water heater (automatic storage) in 1889, founded the Ruud Manufacturing Company, which is still in operation today, and pioneered the advancement of them, in both the residential and commercial market. The Water Heater is still sometimes referred to as a geyser in the UK.

It can be astounding to recognize that only two decades ago the first electric scooter was invented—weighing nearly 250 pounds! Records show that the first patent for an electric personal transport device, an electric motorcycle by chance, was filed in late 1895 by inventor Ogden Bolten Jr. of Ohio, United States.

The first electricity-generating wind turbine was invented in 1888 in Cleveland, Ohio by Charles F. Brush. The turbine's diameter was 17 meters (50 feet), it had 144 rotor blades made of cedar wood, and it generated about 12 kilowatts (kW) of power.

The first commutator DC electric motor capable of turning machinery was invented by British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor was built by American inventor Thomas Davenport, which he patented in 1837.

The modern electric utility industry in America began with Thomas Edison's invention of the first practical light bulb in 1879. Within three years, Edison built the first “centralized” fossil fuel driven power plant at Pearl Street in New York City's financial district.

Canadian executive Thomas Ahearn put together the first electric range in 1892. In 1896, William Hadaway received the first patent for an electric stove, and by the late 1920s, these stoves began to compete with their gas counterparts.

In 1914, engineer Nathaniel B. Wales of Detroit, Michigan, introduced an idea for a practical electric refrigeration unit, which later became the basis for the Kelvinator. A self-contained refrigerator, with a compressor on the bottom of the cabinet was invented by Alfred Mellowes in 1916.

The first heating pad was called “El Warmo.” It was invented in 1911 by a man named Earl Richardson in Ontario, Canada. He was a worker for the local utility company in their area. He was an ingenious man who likes to experiment on things. In fact, he also invented other household items that we still use today.

The name "transformer" was created by Bláthy. In 1885 the ZBD model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (ZBD comes from the initials of their names). In the autumn of 1889 he patented the AC watt-meter.
