The 2 biggest factors affecting fuel economy are1 ) driving
habits and 2) engines not in tune. Together, these factors can
cut your gas mileage by 10 to 20 % !
So called "jackrabbit "starts
waste tons of gas, as it takes much more fuel to accelerate than to
maintain a "cruising speed" that is constant. Slow, gradual
accelerations can also save wear and tear on brakes as well as
stretching your gas dollar significantly farther. In addition, slower
cruising speeds can save 20 to 30% of your fuel, as wind resistance
increases exponentially, , meaning that you can get much better fuel
economy at slower speeds in the 55 to 60 mile per hour range instead of
blasting down the road at speeds in excess of 75miles an hour. Most
drivers are completely unconscious of ther use of the gas pedal, but
with practice, it is easy to change your driving habits and save 10% on
your gas bill.
The single biggest culprit robbing you of fuel could
be a dirty air filter, when it comes to engine tune up.. Dirty air
filters block airflow, causing the engine to run on a "richer" mixture
of fuel , using more fuel to travel the same distance. Dirty
air filters also rob you of engine performance, making performance more
sluggish. When you stop at a service station to get your oil checked,
ask them to also check your air cleaner if it has been awhile since
your last tuneup. If it is dirty, they cost around 10 dollars in most
cases and will save lots of fuel. Vermonters who drive on lots of back
roads will get their air cleaner dirty quicker. top of page
Windows 101
I
worked for a home improvement company for 3 years which specialized in
triple pane windows.In the course of my employment visited over a
thousand homes in Vermont , so I saw lots of windows.The majority of
them were very inefficient and notorious heat losers.
Here are some window basics, as the average Vermonter needs to know a few things about windows.
!)
According to HUD research, windows are the biggest energy wasters in
the average home. Single pane windows can lose heat at nearly 30, 000
BTUs per sq. foot! That's like having a hole in your wall. Its no
wonder larger and older victorian homes can use between 1000 and 2000
gallons of heating oil a year.
2) Windows lose heat 3 ways:
a) drafts (air infiltration) b) radiation directly through the glass ( because glass has virtually no insulation value). c) conduction through the frame.
3) Most
"thermopane" windows made by major window manufacturers such
as Andersen and Harvey are double pane windows made for the
"one size fits all market", which includes areas which do not have long
and severe winters like we do in Vermont.
These windows are not nearly as efficient (even with a low e coating and argon gas the r factor is between 3 and 4. The u factor is similar).
R factor measures center glass whereas u factor measures overall
performance, including the casing. By comparison, the Windows I sold
were rated R9 and had a U factor of 1.9 With u factor the lower the
number the better, which is the opposite of R factor.
The
triple pane windows I sold also had 2 low e coatings and the 2
hermetically sealed chambers were filled with Krypton gas (denser than
air and therefore a better insulator than just a dead air space ).
Bottom
line is that practically speaking, windows are holes in the wall, and
there are only 2 ways to effectively plug the hole . You can board up
the window or u can install triple pane windows with low e coatings and
argon or krypton gas (These gasses are inert and non toxic, and exist
naturally in the atmosphere, along with oxygen ( 18%) nitrogen (78%)
and 2% inert gasses, such as argon and krypton.
4) Windows MUST
be properly installed no matter what type they are . This means that
the casing must be stuffed with insulation and the window must have a
correct "fit,"as well as properly calked. Lots of do it
your-selfers try to to "fudge" the installation of windows
that were not correct size, due to mistakes in measuring or
manufacturing, but they were in love with that low price, so they went
ahead and installed brand new windows which did not function properly
(sort of counterproductive ).
How much can triple pane
replacement windows actually cut heating bills? I make no claims, but
my customers do, and so do the companies that manufacture triple pane
(The only companies that make any specific claim, as opposed to
manufacturers of double pane windows that absolutely never make a
specific claim.)
And just how good are these windows? My
customers themselves claim between 30 and 60 % heat savings!
That's right, and if u don't believe that these people have made such
claims, you can call C.Js Home Improvement 802-864-2284 and ask for a
referral. C.Js has hundreds of references from Vermonters who saved
their butts( in more ways than one) by installing triple pane windows. top of page
Solar power Primer
Solar
power is really nothing new. The Romans had solar heat operating
on the very same principals of todays solar thermal systems.
"Solar Power" really breaks down into 2 general categories.
First, is Solar thermal, a technology which is very simple and
suitable for application in Vermont , which uses heat collectors, which
then store, and then transmit heat energy . Solar thermal collectors
are extremely simple compared to solar photvoltaic, and self reliant
Vermonters can in many cases, design and build a solar thermal system
with locally available materials, on a low budget (see self -help
section) Solar thermal systems are either passive, with no moving
parts, or active, when pumps and other mechanical components are added
to the system.
Second:
Solar Photovoltaic, cells convert sunlight directly to electricity.
Traditionally expensive and difficult to manufacture, Solar cells have
typically been made from Silicon, manufactured in wafers. Recent
breakthroughs in so called "Thin Film" technology have made it
feasible to directly incorporate cells as part of an integerated
roofing material, creating a dual use product, which is therefore,
inherently efficent as well as much more affordable.
In either
case, Vermonters could benefit greatly by making their own energy,
putting money in their pockets in the process, and stimulating the
local economy. In the present situation, every dollar which hits the
gas pump or heating oil bill leaves the Vermont economy to make out of
state, as well as out of country entities even richer, at our
expense! Vermonters who are served by Green Mountain Power
(roughly 25% of the state,) can actually get paid a 6cts per killowat
hr premium to produce their own electricity above the current net
metering rate of 12 ,5 cts per killowat hour . This means that anytime
during peak sun hours, which is, in many cases when many people are not
home and home usage is low, they can put money in their pockets in the
form of a substantial reduction of their electric bill, without having
to purchase batteries to store electricity, traditionally the
weak as well as most expensive point in solar electric systems.
With
the already steep and ever increasing electric bills vermonters already
face solar electric is theoretically feasible right now, from a
strictly economic payback point of view.
The problem is, most
cannot afford the initial investment required, as they are
between a rock and a hard place, so to speak, namely already too
strapped by fuel bills , both for home and car. That is why part of my
"Rainy Day Proposal "is modeled after San Francisco's recent
announcement to provide a solar subsidy to every homeowner, as well as
businesses, in order to jump start solarelectric power production.
But I also believe that this is the only "economic stimulus program
"that will actually work! top of page
Solar Myths and Realities
I have often heard people say that solar power doesn't "work " in
Vermont. It' s as if they said that a solar cell knows the minute it
crosses state lines and shuts itself off. Well, N.E.K. jokes
aside , solar power could provide much more power to Vermont homes and
businesses, than our politicians seem to believe, when they call for
such puny so called goals of 10 or 20 percent local self
reliance sometime in the mid century. Berlin has a
reputation for being a leader in solar applications, with extensive use
of both photovoltaic as well as solar thermal systems, at the same time
that they also have a reputation for having lots of cloudy weather,
even more so than Vermont. Obviously Germany Knows something that we
don't know in Vermont, that namely, these aforementioned technologies
can actually provide 50% or more of energy needs .
Here’s why: If every home and business in Vermont were retrofitted ,
where possible, with solar thermal technology for both heating and hot
water, we could indeed cut our bills in half, and that's with out a
window conversion to triple pane!
As for triple pane windows,
since the average home losses 70 percent of their heat from windows
that aren't much better than holes in the wall , simply by plugging the
holes with triple pane windows (see section on triple
pane windows and heat savings of 30 to 60 percent) , WITHOUT A SOLAR
RETROFIT YOU COULD SAVE BETWEEN 30 AND 60 PERCENT ON YOUR HEATING
BILL
The fact is, that if we applied both approaches we could
save far more than anyone has dreamed possible. But the more you study
the concept of efficiency and apply it to our specific energy crisis,
the more one starts to realize how incredibly inefficient we are as
people when it comes to energy consumption. The
underlying business application of the word efficiency boils down to
this: more efficiency = more productivity. More
productivity means more money in our pockets So, if we were to think of
our energy consumption from a business standpoint, the more efficient
we become as energy consumers, the more money we put in our pockets to
spend for other things we need. I This is also one of the keys to
my economic stimulus plan. Ironically, part of the equation is for us
to move in the direction of becoming more as PRODUCERS of
energy than as passive recipients ie: CONSUMERS! top of page
Improper
tire inflation (under-inflation) can reduce gas mileage, but not by
nearly as much as the previously mentioned factors. Sometimes tires are
over -inflated on the mistaken notion that it will improve fuel
economy. All you accomplish, besides making your car less stable is
premature wear of the center tread, and since tires are a petrochemical
product, you will waste your tires needlessly. Cold
weather starting tips: Get your battery tested in the fall, if it is
weak, replace it. At 0 degrees Fahrenheit, a new battery can lose 50%
of its charge, and more in sub-zero weather. In addition, your engine
oil is much thicker, making it harder to start the car. Engine block
heaters which attach to the oil pan (the flat - bottom part of the
motor) with a magnet can help a great deal, by keeping engine oil warm,
and making it much easier for the "starter motor" to turn the engine
and start the car. If you are mechanically self-reliant, you might
try removing the battery and bringing it inside to keep it warm
overnight. . If you do this, make sure to wear safety glasses and
protective gloves, and do not put the battery next to your wood stove,
either. Ether, also known as "starting fluid" can be helpful, but it
can also damage the motor, or cause an engine intake fire, if you have
already "flooded" your engine attempting to start it. If you do
use starting fluid, spray a very small amount in the opening of the air
cleaner, and if it still doesn't start, you need a tune-up. top of page
Do it Yourself solar primer. There
is good news for self reliant Vermonters, and that is, that those who
posess basic home improvement skills, namely carpentry and plumbing ,
can actually build their own solar hot water system, using recycled
materials, for as little as a few hundred dollars!
Thats right, a simple solar thermal hot water system can be built
relatively easily for those who already posess basic skills, and the
ability to recycle a "decomissioned "electric hot water heater. Usually
the only thing that is wrong with a malfunctioning electric hot water
heater is that the heating element is burned out. But since you are
only using the hot water heater to store water, as the sun will brovide
the heat, these former appliances can actually gain new life and
usefulness, and recycling manufactured products is also a great way to
save energy, as a considerable ammount of energy was "invested" into
the manufacturing process (This is why it is also desirable to
recycle ALL MANUFACTURED GOODS WHEN FEASIBLE ) There are several very good websites which offer free information, as well as actual design plans for such systems. builditsolar.com
has lots of comprehensive general info explaining the various types of
solar heating designs that are now available. motherearthnews.com
also has interesting and low budget do it yourself plans for a "solar
heat grabber" as well as a plan to actually recycle storm windows,and
turn them into solar heat collectiors, for pennies. There is also
a site which is actually an on line advertisement for a manual for do
it yourselfers which costs 49 dollars. It might be worth the money, but
not necessary if you have a tight budget, as these sites I reviewed
have lots of free info as well as free plans.
Bottom line is, that many self reliant Vermonters can significantly cut
their utility bills by becoming energy producers instead of helpless
consumers, at the mercy of out of state forces controlling the price of
oil. THE COMBINATION OF TRIPLE PANE WINDOWS, PROPER INSULATION,
AND SOLAR THERMAL HEATING COULD CUT OUR OIL BILL BY 50% or more, and
may in fact be the only real solution to the situation we are in now.
By the way, for those who are more self reliant, please give your
neighbors some help getting thru this winter IF YOU CAN , by
volunteering to help a neighbor in need, especially if they are senior
citizens. All it takes is a little recycling, a small ammount of
dollars,and a weekend volunteered to help your community get thru this
winter. And for those who are not able to "do it
yourself" see my rainy day proposal , specifically the solar
grant program I am proposing, inspired by a similar approach taken
in San Francisco, which gives 5000 dollar grants to residences to
do solar heating retrofits. Anyone who has any good
ideas to share in the Winter survival tips section,is encouraged
to contribute an article for the site. Also, please tell others about
the "Rainy Day Prorpsal" and direct them to my website. Let
EVERYONE be a community organizer. By doing so, we can
create the necessary political pressure to wake up our so called
"leaders" who seem to be relatively clueless at best regarding our
current energy dilemna, even if they are well- intentioned. "When the people lead, the leaders will follow".
If
your Town, Community group, school or church would like to learn more
about solar power , including a do -it yourself low budget section,
please contact me. I am willing to come to your community to conduct
workshops. I am offering to teach , with the help of my staff ,
workshops to help Vermonters "go solar" by providing practical
information including low- budget solutions, In this
way,communities can learn to harness the sun, as well as our
future. My email is jerrypilot2000@yahoo.com
Homesharing is really a self explanatory term in the context of a winter fuel oil crisis. What
I am suggesting, specifically, is that each family, or household team
up with another and take turns trading off as hosts of a "slumber
party". In this way, the thermostat can be turned down (to only the
point necessary to prevent pipes from freeszing), when you are at your
friends house. They , in turn can enjoy the same savings when it is
your turn to "host" the party. I suggest that people
bring musical instruments, or DVDs, or anything appropriate, to help
pass the time. Parents can organize study groups, pooling their
resources in a collective effort to get the homework done. \ Its
going to be a tough winter, but maybe its possible to have some fun in
the process of neighborly efforts to cooperate collectively!
