Electrical Plan
Objective
Choose
an alternative electrical power system
Many "survivalists" are preaching that you
should prepare for a total-long term (years) loss of the power grid.
While that potential exists, it is a very remote possibility. Even
with a full economic collapse, the federal government cannot maintain
control without maintaining the electric and water infrastructures.
Historically, governments have always taken actions that ensures their
control until the bitter end. Given that bureaucracies and
governments have an very strong survival instinct, expect a
nationalization of the power and water systems because they know that
without these systems, the government will cease to function.
Living with no electrical power can be very
difficult for even just a few days. Most people will not be able
to create an off-the-grid power system for a long term (months)
condition. Unless they use significantly less electricity than they do
today.
For the large majority, having a temporary
backup system to provide some power during an short term (2 weeks)
outage is much more realistic option and time frame. Questions to
consider:
A gas generator uses about 1 gallon of
fuel per hour ... how much fuel can you store?
A solar/battery system for a normal full
house load costs over $50,000... what is the smallest solar/battery
system you need that you can afford?
What can you buy to replace traditionally
powered items that can be run on rechargeable batteries or a 12 volt
system? (i.e. TV, Radios, 12 volt DC powered refrigerator)
You may be surprised that you can get by
with very little electrical power if you:
1. Cook without 220volt AC
electricity
2. Heat without electricity
3. Wash and dry clothes without electricity
4. Heat water without electricity
That leaves a very low power generation need
for:
1. DC powered refrigeration
2. Low voltage lighting
3. DC powered security systems
4. Small DC Powered fans to circulate air
5. Cooking with a portable inductive cook top
OPTIONS/Alternatives - Choose how you will respond to
loss of commercial electrical power
1. Prepare for living without any
electricity or,
2. Have battery powered equipment for
lighting, cell phone, etc, or
2. Have equipment for providing some
electricity - small solar units with battery storage, or
3. Have fuel-limited full-power back
up system - propane, gas or diesel generators, or
4. Have a full power solar, wind or
mini-hydro system (battery storage system required)
Cyclic Use of Backup Gas Power Systems
While having an alternate source of electrical power 24/7 is
possible, the expense of installing a full, renewable energy system is
beyond the reach of most people. Consider how much power you
actually need and for what purposes. If you have a backup, gas or
propane powered
electrical generator you would need a large volume of fuel to run 24
hours a day for even ten days (one gallon per hour x 10 days). Instead consider using your
gas generator
for only two to three hours a day to keep you refrigerator and freezer
at optimal temperatures for food and medication preservation and for low
power cooking. Lighting can be provided by lanterns, rechargeable
lighting equipment or candles. Use an induction cook top to heat
water for cooking and bathing. Using this method will also extend the
life of a backup generator. Installing additional insulation to
the outside of freezers and refrigerators will greatly reduce the rise
in internal temperatures when power is off.
Home-Based Electrical Generation
Systems
-
SOLAR PV (photo-voltaic) - determine the
minimum needed and then add 10% - consider getting several portable
systems - redundancy is important. DO NOT use these systems until
you need them. The batteries and electrical control systems will
wear out at some point, so have the small solar systems ready but not
worn-out when you really need them.
-
WIND POWERED GENERATORS - very few places in
U.S. are suited for this type of power generation. You will need storage
batteries the same as solar systems. Moving parts means higher
potential for wear & tear.
-
MINI-HYDRO POWERED GENERATORS - a 365 day free
flow of water down hill is needed for this system to generate even small
amounts of power. Battery storage system is required.
-
GAS POWERED GENERATORS - Tri-fuel generators
are best - Plan for about 1 gallon and hour fuel consumption. Gas
generators need maintenance (valve adjustments) after about 300 hours of
operation. Consider having two 3KW tri-fuel generators. One
on-line and one available when first generator needs repair. 3K won't
run a central Heating & AC unit, but will provide most all of your 110
volt AC needs including refrigerator.
-
SMALL SOLAR BATTERY CHARGERS - Consider having
several to charge batteries.
-
RECHARGEABLE BATTERIES - need power source
such as solar chargers. Have at least 4 sets of batteries for each
battery powered piece of equipment.
-
VEHICLE POWER - can be used to recharge
batteries, but any high load system has potential to over-load and burnout
your car's alternator.
DC Battery Banks
Alternate power systems, powered by solar collectors and
wind generators, rely on power being stored in a battery bank.
Huge inefficiencies are encountered when converting DC power to AC.
An "inverter" is required. A large advantage is gained when
electrical loads are run directly from the battery bank without
converting to AC. This requires having special DC lighting and DC
powered appliances. While DC lighting and appliances are more
costly, the benefit is being able to have a significantly smaller
battery bank as well as a smaller solar collection system (less costly).
There will be some loads that cannot be converted, however using an
single, smaller inverter (designed for use in vehicles) for each of
these - such as cordless phone bases, TVs and microwaves - will prevent
the failure of a single, full-system inverter from disabling your entire
electrical system.
Lower Your
Electrical Requirements
If you plan to install a home-based
electrical power generation system, lowering the overall electrical load
will allow you to have a smaller, less expensive system.
1. Install low power fluorescent light
bulbs or Low-voltage DC lights
2. Use propane to power your water heater,
clothes dryer (heat) and refrigerator or have a 12 volt DC refrigerator
ready to use.
3. Exchange old appliances for energy
efficient models
4. Use
inductive cook
tops (portable and fixed)
5. Use pressure-cookers to speed up
cooking time to use less electrical energy - up to 90% less power or
gas/wood fuel.
6. To make solar power generation
system electrical power use more efficient, use DC powered refrigerators
and other appliances. Also consider installing low-voltage DC
lighting.
7. Implement a non-electrical
alternate heating and cooking plan.
Home-based Electrical
System Choices
Micro-Hydro Systems
There are currently many small micro-hydro systems on the market for home
use. If you have a good stream close by with even a moderate drop in
elevation, this may be an excellent choice.
Solar Generation
Solar electrical systems are the most expensive systems but the have
no moving parts, make no noise, are allowed by building codes nationwide
and can be mounted on your roof or on a motor-swivel system that tracks
the sun. Look for significant improvements and lower costs in the next few
years as new materials technology is integrated into the production of
solar PV cells.
Wind
If you live in an area with more than average windy days and an
average annual wind speeds of at least 9 miles per hour you can
realistically consider a wind power generator. It will have to be
mounted atop a tall tower that is not blocked from the wind by trees,
hills or buildings. Possible problems include: Some jurisdictions,
restrict the height of structures allowed in residential areas. Your
neighbors might object to a wind machine that blocks their view, or they
might be concerned about noise.
Gas Powered Generators
This category includes generators powered by gasoline, diesel, natural
gas and
propane. While appropriate for short term solutions, if the crisis
devolves to a serious breakdown of the electrical power infrastructure,
you will find it hard or impossible to replace your fuel supplies. Hydro-carbon
fueled generators are good for short term events and will provide you some
extra time to transition into a non-electric life style. Check local
ordinances to know how much on-site fuel you can store. Consider
purchasing a tri-fuel generator which can use gasoline, propane or
natural gas.
Fuel Load: A typical portable 8 kilowatt gas generator uses about a
gallon an hour at 85% load. Propane fuel for your electrical
generator is a good option for several reasons. First, you store
your own supply on-site (natural gas supplies could be interrupted) and
propane is easier to store, cheaper and lasts forever. Gasoline and
diesel require treatment for long-term storage.
Extending Your Power
Being able to ration whatever emergency electrical power you have will
be a great benefit. Use compact fluorescent bulbs instead of
incandescent ones. Your electrical lighting load will drop by about
60%. Unplug and open the breakers for all 220 volt loads like your water
heater, clothes dryer, stove and oven. Evaluate carefully what electrical loads you really need. If
you are making long term preparations, consider installing low-voltage DC
powered lighting and appliance throughout your home for a much lower electrical
load. Using DC powered appliances removes the need for an
inefficient "inverter" between storage batteries and the appliances
resulting in much less power drain on your battery bank..
Batteries
Powering your emergency radio, flashlights and other equipment is
essential. Be sure you keep a large rotating stock of all size
batteries you need. Not all batteries are created equal. Don't
rely on rechargeable batteries unless you have a way to recharge them
during a power outage. Routinely buy extra batteries every month and
mark their date of purchase on the package. Keep them in a cool dry
place. For convenience, buy electronic and equipment that requires
AA batteries. Having to keep up with several different sizes can be
a drag. Keep it simple. Batteries like Duracell can last
several years in their package
