The document discusses electric vehicles including the 2013 Tesla Model S, 2013 Scion iQ EV, 2013 Honda Fit EV, and 2013 Nissan Leaf. It provides the developer and average cost for each vehicle. Advantages of electric cars are that they emit no CO2, have relatively low fuel costs of $1.05 for every 25 miles, can refuel at any outlet, use a renewable resource, and rely less on fossil fuels. Necessary infrastructure upgrades include improving electrical grids and developing faster charging methods. Disadvantages include the need for many infrastructure changes, some consumer reluctance, and limited long-distance travel due to charging needs. The government can provide loans and incentives to promote electric vehicles.
