The grid is vulnerable as a system. We have to stop always thinking
about being connected to or relying on the utility grid. Think in terms
of building an independant 12 volt DC system (low voltage) for the
average dwelling to operate independant of the grid by charging
batteries from solar or wind and utilizing the energy real time or
later from the batteries. It seems everyone has visions of large
expensive rooftop systems but starting small and building up over time
will reduce the utility bill by substitution.
We need to be energy independant on a small scale as well as looking at
the big picture. Small systems can easily run lights, TV’s, radios,
even a small refridgerator for essentials. You would still need the
grid power for large loads like heat, large refridgerators, etc but you
can have a seperate system to rely on if you suffer some calamity.
With the advent of the “smart” grid, you dont want to be connected to
the grid. Remember, the wires are antennas as well as conducting
electricity. We owe our reliance on a large electrical system to
Nickolai Tesla who developed high voltage alternating current power
systems that won out over Thomas Edisons Direct Current system around
the turn of the last century. The idea was to minmize power loss over
long distances. Therefore we should all promote local or household Low
voltage DC solar or wind systems to reduce the use of grid power and
for much better reliability.
Through the years I have built a very economical system comprised of
several solar panels with a capacity of about 130 watts that
automatically charge 6 large deep cycle and regular batteries from
which I operate some radios , lights and in the event of loss of
utility power, a small refridgerator. I also have a couple of cheap
store bought DC to AC inverters if I need to operate an AC device,
Solar panels have come down in price dramatically and production
capabity is expanding, so start now. Think independant and start small
instead of suffering mega system price hesitance.
A world of 12 volt dc devices are available from hardware, marine,
automotive and internet sources. You just have to start.
Be the first on your block to confuse the lineman who show up during a
power failure. I did.
I posted the above text on the new york times "Green Inc" energy blog
back on september 23, 2009 as a comment to an article regarding solar
power in africa. The internal discharge in a deep cycle battery is only
about 50 milliamps which I consider insignificant.
I dont want to be connected to the grid which I consider "STUPID" and
you dont either. Dont follow, think for yourselves.
Think about this..... brain waves operate up to about 20 cycles per
second, imagine what 60 cycles is doing to you and the world.
