Subject: Why not use electricity directly, not fuel cells to power cars?

Doing a special report for school about alternative energy for vehicles.  
Research says creating hydrogen is difficult, expensive, dangerous.  And then, 
all it does is power the electric motor in a car.  Then why not go directly 
from electricity that's already being generated (and create more sources for 
that: like wind, solar) to power an electric motor in a car?  Why the extra 
step?  We had an electric car.  It was great.
