^Why aren't we solar powered yet and can't be for some time to
come (by Kenneth Udut but you can use it freely)
The trouble though is this:
http://notrickszone.com/2014/03/25/analysis-shows-solar-modules-cause-more-greenhouse-gas-emissions-than-modern-coal-power-plants/
Our current style of production of solar panels creates more
greenhouse gases even than coal.
"The passage of time does not change the inherent differences
between different types of fuels. Oil is still the fuel of
preference for long-distance travel, because (a) it is energy
dense so it fits in a relatively small tank, (b) it is a liquid,
so it is easy to dispense at refueling stations, and (c) we are
now set up for liquid fuel use, with a huge number of cars and
trucks on the road which use oil and refueling stations to serve
these vehicles. Also, oil works much better than electricity for
air transport."

The energy density of oil is very hard to beat.
Without the right kind of batteries/fuel cells at the right
price, and without manufacturing methods that aren't worse than
current methods; PLUS the fact that consumers (residential and
commercial) need to get the value out of their current purchases
(which will take at least a generation) - adaption of solar
energy will take some time.
Conversion of airplanes to solar will be the "killer app". It
has to have the raw power.
We're not there yet.
There's a lot we can do to help... but a worldwide conversion to
solar is more than having the right amount of solar panels.
Not everything runs off of a cord.
