A handful of different makes and models of electric cars are exhibited in Chicago.

1897
The first electric taxis hit the streets of New York City early in the year. The Pope Manufacturing Company of Connecticut becomes the first large-scale American electric automobile manufacturer.

1899
Believing that electricity will run autos in the future, Thomas Alva Edison begins his mission to create a long-lasting, powerful battery for commercial automobiles. Though his research yields some improvements to the alkaline battery, he ultimately abandons his quest a decade later.

1900
The electric automobile is in its heyday. Of the 4,192 cars produced in the United States 28 percent are powered by electricity, and electric autos represent about one-third of all cars found on the roads of New York City, Boston, and Chicago.

Henry Ford introduces the mass-produced and gasoline-powered Model T, which will have a profound effect on the U.S. automobile market.

1912
Charles Kettering invents the first practical electric automobile starter. Kettering's invention makes gasoline-powered autos more alluring to consumers by eliminating the unwieldy hand crank starter and ultimately helps pave the way for the electric car's demise.

1920
During the 1920s the electric car ceases to be a viable commercial product. The electric car's downfall is attributable to a number of factors, including the desire for longer distance vehicles, their lack of horsepower, and the ready availability of gasoline.

1966
Congress introduces the earliest bills recommending use of electric vehicles as a means of reducing air pollution. A Gallup poll indicates that 33 million Americans are interested in electric vehicles.

1970s
Concerns about the soaring price of oil -- peaking with the Arab Oil Embargo of 1973 -- and a growing environmental movement result in renewed interests in electric cars from both consumers and producers.

Vanguard-Sebring's CitiCar makes its debut at the Electric Vehicle Symposium in Washington, D.C. The CitiCar has a top speed of over 30 mph and a reliable warm-weather range of 40 miles. By 1975 the company is the sixth largest automaker in the U.S. but is dissolved only a few years later.

1975
The U.S. Postal Service purchases 350 electric delivery jeeps from AM General, a division of AMC, to be used in a test program.

Congress passes the Electric and Hybrid Vehicle Research, Development, and Demonstration Act. The law is intended to spur the development of new technologies including improved batteries, motors, and other hybrid-electric components.

1988
Roger Smith, CEO of G.M. , agrees to fund research efforts to build a practical consumer electric car. G.M. teams up with California's AeroVironment to design what would become the EV1, which one employee called "the world's most efficient production vehicle." Some electric vehicle enthusiasts have speculated that the EV1 was never undertaken as a serious commercial venture by the large automaker.

1990
California passes its Zero Emission Vehicle (ZEV) Mandate, which requires two percent of the state's vehicles to have no emissions by 1998 and 10 percent by 2003. The law is repeatedly weakened over the next decade to reduce the number of pure ZEVs it requires.
