My Hybrid speech

A hybrid is any vehicle that uses two or more sources of power for propulsion.

Most hybrid cars are built in the economy car mold. Compared with cars that have similar designs and features, a hybrid car can cost 25 to 30 percent more than a comparable car,

While electric cars are expensive and can double your energy bill when re-charging at home, many early adopters say they're still worth the price, since they help the environment and reduce the need for foreign oil.

The reasons why smart people do not buy Electric or Hybrid cars are: Batteries are expensive, short lived, efficiency isn’t 100 % and the electricity is not free. Going electric you won’t decrease Air Pollution because 50 % of the electricity is produced by burning COAL. By the way a Jetta Diesel, TDI for $23000 makes 40MPG. With a full tank of Chevy Volt, driving non-stop, you make 37MPG, plus $3 or more, the price of electricity you charged 16.0-kW-hr lithium-ion, the hefty 750-pound batterypack.

Electric cars actually harm the environment more than their gas-powered counterparts in many places

the report said—they may even wind up causing more carbon emissions than gas burners. In addition, electric car batteries require toxic minerals like nickel, copper, and aluminum, increasing the potential for acidification
