Using renewable energy is one of the most important things that you
can do as a home owner. There are various advantages to using
renewable energy at your home. Using renewable energy can be something
that can help both you (as an individual) and the world (as a whole).
There are various options that are available to you as a home owner,
when you use renewable energy.
The most common type of renewable energy is definitely solar energy.
This energy is used to create hot water at your home and it can also
be used to generate electricity by using photovoltaic cells. Although
the energy conversion of solar power to electricity has low
efficiency, the cost of producing this energy is much more lower than
other forms of renewable energy.
The second type of renewable energy is wind energy. By using a
residential wind turbine system, you can reduce your electric bill
considerably. The wind system is constricted of a wind mill and a
turbine. As the wind blows, the kinetic energy of the wind is
transformed into electricity via wind turbine. If the wind is fast
enough, then the residential system will produce enough electricity
for your home. If the wind speed is below the required amount, then
the system will be offline and you will use electricity from your
local utility company. However, in case the wind speed is high enough
to produce more electricity then you can use at that time, you can
even sell that excess electricity to your local utility company in
For residential use, you can also use geothermal energy for your
heating needs. Although geothermal energy can not be used to produce
electricity, it can be used to efficiently heat your house. In some
geothermal systems, it is even possible to cool your house.
As you can see, using renewable energy can be very advantageous to
provide electricity to your home or to heat up your home. Although the
initial costs of your residential renewable energy system can be high,
in 10 years or so, you will have gotten back your initial investment
and you will continue to save money on your power bills. In addition,
you can avail yourself of federal incentives and most importantly your
home will gain in value when you decide to sell your home in the

Nice! Two spams from this fellow in one day.

DP, what have YOU personally done to reduce your energy demand, and
can you report the measured results???
Karma points for feel-good postings don't count.

I mostly lurk here, but this answer prompted a question that perhaps
this group can answer. I'm retired and would love to install solar
panels, but the up front cost are prohibitive. Here in Tennessee
solar is probably the way to go, since it's not windy and geothermal
is expensive in rock. I can't help but feel the people who sell solar
panels are gouging their customers. I would seriously consider
borrowing money to install solar but can't help feeling that I'm
getting taken for a ride.
Does anyone have any data on the profit margin that the people who
sell to the public make? If it cost $00 to make a panel, but they
sell it to me for $00 I feel this is unfair. If it costs $00 and
sold for $20 then the margin would be a bit more acceptable. Most
business (excluding energy) operates on margins that allow them to
stay in business and pay the stockholders a reasonable return. I just
find it hard to believe that it costs so much to make a solar panel.
Do they figure into the cost the savings the consumer might realize?

Well, let's see...
The panels at http://www.iedu.com/DeSoto/solar.html were built with
about $00 worth of materials and two man-weeks of labor. You should
apply TN labor rates, benefits, and taxes to arrive at your "fair" labor
content. Palletizing and shipping from my shop to your local dealer
shouldn't have been much over $00.
Oh yeah, my shop. The shop itself cost me $50/month and additional
storage space cost just under $50/month - let's lump it all together
and notice an $00/month rental overhead. You might be able to do better
in TN, but around here that got me 2500 ft^2 of manufacturing space
without heat, lights, toilets, or snow removal.
Inside the shop is tooling that cost in the ballpark of $0K, the most
expensive component of which is a CNC router - needed because some of
the parts of those panels just can't reasonably be manufactured any
The panels in the photo took about six years of R&D to produce. While
you're not liking the price, I'm not much liking the cost associated
with getting to the point where I could offer a first-class product.
I don't have stockholders. Good thing because they'd have lynched me
long ago - there aren't any profits anywhere in the picture. So far I'm
about $00K behind the game, and have yet to draw a paycheck from the
You can avoid the shipping costs if you buy from a local producer. :)
