$this->bbcode_second_pass_quote('', 'W')here you going to get the electricity from? Natural gas is already peaking here in NA and can't readily be transported across oceans, at least not at the scale we need.
At best, you have a coal powered car.
Matt, I'm surprised at you.
One of the first things we have to do is use energy more efficiently.
Electric vehicles are some of the most efficient vehicles on the road.
Our Solectria Force uses less than 200Wh/mile from the wall.
For comparison, a Prius is using around 700Wh/mile and that is one of
the most efficient gas cars (with significant energy efficiency gains from
using electric components in the drivetrain). In contrast, a
fleet-average gas car is using about 1700Wh/mile.
So simply switching to electric drive can vastly reduce our energy usage.
Also, oil refining is a huge electricity consumer, certainly here in CA.
Remove the need for, or availability of, all that oil and we have a huge
number of miles available for EV driving. On top of that, PG&E and
other utilities have surplus capacity at night which is when EVs are
typically recharged. That's why we pay half-price after midnight for
our kWhs. Of course switching to an EV also opens up the possibility
of "fuelling" your car from renewable sources. Many EV'ers that I know
already power their EVs (and their homes) via PV on their house roof.
It's being done now. OK, so we need to scale up but this is happening all
around you, locally, with today's technology and regular people who think
it makes economic sense right now.
