As has been publicized, we don't have the grid capacity to support
much in the way of all electric cars. The same is true for Hydrogen.
It's either produced from fossil fuels with a lot of polluting
byproducts or takes a whale of a lot of electrical energy to produce
from water.

When/if worldwide photovoltaic production ever meets consumer demand,
you are going to see an enormous increase in solar power
installations, not only in commercial buildings, but residences as
well. Today, the excess electricity generated by a home's
photovoltaic power generating system is used to turn the electric
utility meter backwards. As electrically powered vehicles become more
mainstream, that excess solar power could be used to directly charge
vehicle batteries or for hydro-electrolysis to generate hydrogen gas
for fuel.

Side benefits of residential solar power generation are the peace of
mind inherent in the redundancy of distributed (as opposed to central)
power generation and the resulting robustness against massive power
outages due to a cascade of equipment outages triggered by a
single-source failure, the ability to "thumb the eye" of oil
robber-barons, the reduction in the production of pollutants,
insurance against the inevitable increases in the price of energy, and
virtue of abandoning 19th century technology for a more enlightened
solution.

Alcohol is an interim solution with the hybrid being by far the most
economical and quickest to implement of the interim solutions.

As for grid capacity we are rapidly coming to the point of real time
usage monitoring with remote setback of heating and air conditioning.
Here with peak rates of about 10 cents per KWH we wouldn't see the
savings of those fortunate souls paying 38 cents during peak demand
out in the Republik of Kalafornia.

OTOH solar panels don't do us much good either.

Why? Photovoltaic panels are able to convert infrared isolation even
on cloudy days.
