between 1882 and 1886 schuyler wheeler invented a fan powered by electricity. it was commercially marketed by the american firm crocker & curtis electric motor company. in 1882, philip diehl developed the world's first electric ceiling fan. during this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 20th century.

meanwhile, electric ceiling fans became very popular in other countries, particularly those with hot climates, such as india and the middle east, where a lack of infrastructure and/or financial resources made energy-hungry and complex freon-based air conditioning equipment impractical. in 1973, texas entrepreneur h. w. (hub) markwardt began importing highly efficient ceiling fans to the united states that were manufactured in india by crompton greaves, ltd. crompton greaves had been manufacturing ceiling fans since 1937 through a joint venture formed by greaves cotton of india and crompton parkinson of england, and had perfected the world's most energy efficient ceiling fans thanks to its patented 20 pole induction motor with a highly efficient heat-dissipating cast aluminum rotor. these indian manufactured ceiling fans caught on slowly at first, but markwardt's encon industries branded ceiling fans (which stood for energy conservation) eventually found great success during the energy crisis of the late 1970s and early 1980s, since they consumed far less energy (under 70 watts of electricity) than the antiquated shaded pole motors used in most other american made fans. the fans became very effective energy saving appliances for residential and commercial use by supplementing expensive air conditioning with a cooling wind-chill effect. fans used for comfort create a wind chill by increasing the heat transfer coefficient, but do not lower temperatures directly.
