Depends on how you look at it.
Take a look at the chart at
<http://en.wikipedia.org/wiki/
Energy_density#Energy_density_in_energy_...>
A Zinc battery is low on the chart, while hydrocarbons are much
higher in MJ/kg and MJ/L. You see airplanes powered by hydrocarbons,
but not batteries. I think there was an experimental solar cell
powered plane a few years ago, but the weight of the solar cells
precluded any cargo to talk about.
I am thinking that gasoline and jet fuel are a higher energy
density
resource that is easier to handle, and safer than most other
products.
I agree electric is better for getting around on the ground,
assuming we are using a renewable source of energy to charge the
batteries we have to lug around to do it.

flying, and not applicable to the taste or misson statement of
most pilots.
Sonex, always coming up with something different,
(and ugly, lol) has an electric version of their bird;

and they also stuck a jet on one of these, but I never saw it fly;
http://www.youtube.com/watch?v=6gZsXvyxjQ0. Mostly it flys with
the wonderful powerplant, the Jabiru 3300 ( Aussie design), which
can be found in what is probably the number one light sport plane
in the world, the Arion Lightning, made in Tennessee.

But I digress. When I think electric, I *don't* think
airplane, because the weight factor makes it impossible
for anything other than novelity applications and speciality
flights.
I think we need something better than batteries, or
what we now think of as batteries, to store power.
Graphene, a carbon material which has been nano
engineered was supposed to be part of the revolution.
http://en.wikipedia.org/wiki/Graphene
You know, it seems that M.I.T. or someone is always
developing answers, but then you never hear much
about it after that. Like solar panels which concentrate
the light to an efficiency 100 times greater than what's
on the market, so, they are smaller and use less material.
I wish these scientists would get on the ball.
