    Though Thomas Davenport was among the first to install an electric motor into a vehicle, an electric car in the conventional sense was not developed until 1890 or 1891, by William Morrison of Des Moines, Iowa; the vehicle was a six-passenger wagon capable of reaching a speed of 14 miles per hour (23 km/h). It was not until 1895 that Americans began to devote attention to electric vehicles, after A.L. Ryker introduced the first electric tricycles to the U.S., by that point, Europeans had been making use of electric tricycles, bicycles, and cars for almost 15 years. Many innovations followed, and interest in motor vehicles increased greatly in the late 1890s and early 1900s. In 1897, electric vehicles found their first commercial application as a fleet of electrical New York City taxis, built by the Electric Carriage and Wagon Company of Philadelphia, was established. Electric cars were produced in the U.S. by Anthony Electric, Baker, Columbia, Anderson, Edison, Studebaker, Riker, and others during the early 20th century. In 1917, the first gasoline-electric hybrid car was released by the Woods Motor Vehicle Company of Chicago. The hybrid was a commercial failure, proving to be too slow for its price, and too difficult to service.

    Due to technological limitations and the lack of transistor-based electric technology, the top speed of these early electric vehicles was limited to about 32 km/h (20 mph). Despite their relatively slow speed, electric vehicles had a number of advantages over their early-1900s competitors. They did not have the vibration, smell, and noise associated with gasoline cars. Changing gears on gasoline cars was the most difficult part of driving, and electric vehicles did not require gear changes. While steam-powered cars also had no gear shifting, they suffered from long start-up times of up to 45 minutes on cold mornings. The steam cars had less range before needing water than an electric car's range on a single charge. Electric cars found popularity among well-heeled customers who used them as city cars, where their limited range proved to be even less of a disadvantage. The cars were also preferred because they did not require a manual effort to start, as did gasoline cars which featured a hand crank to start the engine. Electric cars were often marketed as suitable vehicles for women drivers due to this ease of operation; in fact, early electric cars were stigmatized by the perception that they were "women's cars", leading some companies to affix radiators to the front to disguise the car's propulsion system.

    Acceptance of electric cars was initially hampered by a lack of power infrastructure, but by 1912, many homes were wired for electricity, enabling a surge in the popularity of the cars. At the turn of the century, 40 percent of American automobiles were powered by steam, 38 percent by electricity, and 22 percent by gasoline. 33,842 electric cars were registered in the United States, and America became the country where electric cars had gained the most acceptance. While basic electric cars cost under $1,000 (in 1900 dollars, roughly $26,000 today), most early electric vehicles were massive, ornate carriages designed for the upper-class customers that made them popular. They featured luxurious interiors, replete with expensive materials, and averaged $3,000 by 1900 (roughly $78,000 today). Sales of electric cars peaked in 1912.

    In order to overcome the limited operating range of electric vehicles, and the lack of recharging infrastructure, a exchangeable battery service was first proposed as early as 1896. The concept was first put into practice by Hartford Electric Light Company through the GeVeCo battery service and initially available for electric trucks. The vehicle owner purchased the vehicle from General Electric Company (GVC) without a battery and the electricity was purchase from Hartford Electric through an exchangeable battery. The owner paid a variable per-mile charge and a monthly service fee to cover maintenance and storage of the truck. Both vehicles and batteries were modified to facilitate a fast battery exchange. The service was provided between 1910 to 1924 and during that periord covered more than 6 million miles. Beginning in 1917 a similar successful service was operated in Chicago for owners of Milburn Light Electric cars who also could buy the vehicle without the batteries.

    Hmm.... It appears there are no forecasts for this. It seems that energy futures analysis is being complicated, mostly by transitory geo-political issues, and overly hyped environmental issues. The things we are fairly certain will happen: 1) Petroleum will still exist, and should be near current values. 2) Biofuels will see an increased use, with additional farmland being pressed into service. 3) Despite government efforts to push hydrogen fueled vehicles, the technology has already reached its maximum potential, and will fail for various economic, environmental, and physical reasons. The idea of a hydrogen fueled car will become something of a throw-back, just like personal air vehicles and the robotic kitchen. 4) Additional research, and the trials of time, will show that the hysteria over global warming was largely unjustified. Some policies may be in place to limit CO2, but they will not be as extreme as what currently exists. New oil sources will be opened to drilling, and formerly "depleted" sources will be revisited. 5) With lighter body materials and slightly more advanced batteries, electric (battery) vehicles may see an increase in range towards 200 miles, with a recharge time of a few hours. However, they will still cost about the same, in comparison to combustion vehicles. The problems are that we have no ideas when the public opinions and government policies will change. We know they will change, but the number of electric cars will be influenced by when, which will be influenced by who wins elections and what-not. For example, if Republicans maintain a strong presence in Congress and keep the Presidency, then it is likely that government will have a largely "hands-off" approach. This will leave the industry at the will of market forces, which will favor the continued use of combustion vehicles, well into 2030, although many multi-car families may start buying electric commuting cars. If Democrats gain control of Congress and the Presidency, they will move government to being much more intrusive. Large sums of money will be spent on a hydrogen infrastructure (which will ultimately go unused), and new oil finds will remain untapped, drastically increasing the price of oil. In an attempt to reduce the price, they will drain the strategic reserve, setting the United States up for an energy catastrophe. They will also implement a carbon credit trading scheme which will further increase the cost of energy. The end result is that gasoline will reach roughly $6 per gallon by 2012, and $10 per gallon by 2016. People will rapidly adopt electric cars at that time. Inevitably, people are not stupid, and will recognize the failures of the Democrat Congress and President, and they will be replaced with Republicans who will counter many of the destructive policies. Gasoline will rapidly drop back to $4 - $5 per gallon. However, people will probably continue to use electric cars for their normal commuting, although the number on the road will decline starting from 2018. So you see, there are two scenarios which have drastically different outcomes. In one scenario, market forces cause a gradual adoption, while in the other scenario, government interference will cause a rapid adoption followed by a decline as market forces are reasserted. The thing you really need to focus on though, is that in 2030 the energy sources will be pretty much the same as they are today, but with more potential for biofuels. Battery powered vehicles will also have the same disadvantages as they have today. Similar market forces usually mean a similar outcome.
