Wood is the original alternative renewable energy source
Why not wood for energy? It's the original renewable energy source and
has been used since "fire" was first discovered. Today's woodburning
stoves are very efficient and can also be very attractive.
Wood stoves come in a wide variety of styles. Those that are installed
in the main living areas are generally very pleasing to the eye as well
as being very energy efficient. They come in both free standing styles
and also as fireplace inserts. Many have built-in "windows" to allow
viewing of the fire without comprimising their efficiency or safety.
The ones that are installed in the basement are generally not designed
to be as visually attractive, but instead are made to be used either
the as the primary heating source or as a supplimental source of heating.
They usually are installed in parallel with the original heating plant
so that they can easily be switched back and forth. Another variation
is to locate the wood stove outside in a separate, detached enclosure
completely separate from the living area. This is particularily
appealing to those that may be concerned about any fire danger that
may be associated with wood burning stoves. Of course, this requires
extra expense in bringing the heat back into the living area. It's
usually accomplished by heating water and then pumping that back into
the home for heating there. This is naturally less efficient, but some
are willing to sacrifice that for increased peace of mind on the side
of their safety concerns.
However you look at it, there's a very large source of completely
renewabe energy producing material in the form of wood. There have
been studies done in the state of Michigan that showed that all of the
energy requirements for the entire state could be supplied without
ever cutting down even one tree! There are so many trees down in that
state's forests from storms and other natural causes that just those
already downed trees could be harvested and used to supply all the
energy needed to meet their current demand!
Of course, we're primarily dealing with what are referred to as
"airtight" stoves. We're not concerned with the cheap "Franklin" style
stoves that do burn wood, but don't give much heat back into the living
area. Most of the heat from these simply goes up the chimney and use a
lot of wood inefficiently. Forget those. The good "airtight" stoves
come in many sizes and shapes. Generally speaking, the smaller ones
work well, but don't have big enough fire boxes to be very practical
for serious heating of large areas. They only burn for about 4-8 hours
and require a lot of tending to keep them burning hot. I recommend
getting one with a medium to large firebox. They can use larger logs
and can be "stacked" to burn overnight without tending.
Another interesting idea is the "Pellet" burning stoves. They can be
set up to burn for days without tending with their optional automatic
feeding systems. The drawback is that you can't "harvest" these pellets
in your own woods. They must be purchased from a retail outlet at the
going market rates. A variation of this idea uses dried corn kernels
which are much less expensive and burn very well. They have the
disadvantage of causing many more "jams" that stop the automatic
feeding of the stove. However, if you're already a corn farmer or have
enough land to grow your own, this is certainly a very practical way
to go if you don't mind clearing an occaisional jamming of the feeder
system. And, of course, this is also a renewable source of energy.
As you can see, I really like the wood stove as a very efficient and
inexpensive form of alternative energy for creating heat. Also, once
again in the State of Michigan, there has been some research into
using wood to fire boilers for creating steam to turn turbines for
electric generating plants. These preliminary studies concluded that
a very significant percentage of the state's electric power needs
could be produced using wood as the energy source. This involved a
unique system of using wood "chips" to be used to make a very efficient
and hot fire to create the steam. It's a very interesting idea that
never got very far primarily due to the fact that fossil fuels remain
relatively inexpensive.
There's one other very nice advantage to using wood for heating your
home. It provides a very pleasing atmosphere and it gives off a
steady source of heat. You don't have the ups and downs of forced air
heating that can be uncomfortable and irritating. The steady supply of
warm air from your wood stove is very comfortable and reassuring. And,
there's nothing like looking into the fire and seeing all the interesting
shapes and glows that are so relaxing. There's nothing like coming in
from the cold outside and kicking back with your shoes off and soaking
up the heat from the fire!
