Renewable Energy Hacking
How
much power is enough?
Americans love using power.
I should know. I use plenty. As a visual aid, I have next to me a
16 gallon barrel. This represents how much
gasoline my vehicle uses in just one week. Many people use
much more than this when they tank up their oversized SUVs several
times a week. This barrel would be much larger if it represented
the amount of energy (oil or otherwise) that I use to heat my house, cook
my food, heat water for a shower, and provide electricity to run my computer.
It also doesn't represent the tremendous quantity of energy needed to transport
or make the various goods I use. What is shocking is that cheap liquid
energy of this nature will become more expensive and may become unaffordable
in the decades ahead. Because oil will become more expensive, some
predict dire consequences
while others think there is no
problem at all. I have the opinion that the next few years will
be somewhere in between. It will be rough - but steps taken now might
ease our transition into a post
oil world and avoid the
end of civilization.
How big of a crisis is
this?
Depends on your time horizon.
In the next five years, petrol products will be expensive but still affordable
for most people. However in the next fifty years, major changes will
start happening. There are several areas of promising technology
that may help in the short term (the next few decades). One of them
is providing petrol products from coal using Coal
Gasification. Another short-term transition technology is Nuclear
Power. Since people much more qualified that I am are working on these
solutions, I will leave investigation of these alternatives to the reader.
This site will instead concentrate on what renewable sources could be used
for the longer term (50 years and
beyond).
What should we do now?
For my household, I have
found that conserving is still the least expensive, easiest and highest
return option to save energy. Carpooling works well as does taking
train, bus or bicycle when possible. When using an automobile, I
try to combine trips. When it comes time to replace my auto, you
can be sure that it will be one that has a much higher mileage rating than
my gas guzzling 24MPG car. Although I have a small window air conditioner
- I usually use a low
power ceiling fan I bought for $15 at Walmart. For the winter,
I use additional plastic sheeting on my windows to keep the heat in.
I have also switched to high
efficiency florescent lighting and I am now in the habit of switching
off all vampire
appliances by powerstrip when not in use. For cooking, I use
a microwave when possible instead of an electric oven. I also have a flow
reducer in my shower (not so much to save water - just to save HOT water).
All of these steps have taken a substantial bite out of my monthly utility
bill. While all of these steps will help, just conserving is unlikely
to be enough in the years ahead.
What else can be done?
In addition to conserving,
I will be exploring various renewable systems that collect energy and deliver
it in a useful form. I think of researching such systems as a personal
challenge. I will be concentrating on solutions with an emphasis
on replacing household power or household transportation. Candidate
energy systems include biodiesel, ethanol, methanol, solar and micro-woodgas.
Other systems such as hydro, tidal, biogas, geothermal and wind were eliminated
from my list for now since I don't have useful quantities of these sources
in my area. The overall goal is to find real world pitfalls of renewable
energy solutions NOW rather than LATER. Some solutions might
work - others might not. But if they don't work, I'm just a hardware
store away from fixing or abandoning the technology. In a few years,
that might not be true! By finding the problems now, the cost
of making mistakes will be much lower should I (we) need to depend on such
a technology!
Renewable energy systems
are challenging even if you're not on the 3rd world.
I am finding that small
renewable systems can be challenging to buy and maintain even for a person
in a developed country. One major problem is that once outside support
goes away, a system can become useless due to failures of hard to get parts
or lack of knowledge. In America, we like to think that a lack of
support is only a problem for 3rd world installations but many renewable
systems in the U.S. have failed for the same reason. The lesson is
that energy solutions for an area should match the knowledge, wealth and
tooling base of the area to be considered a long-term winner. I will be
trying some experiments to see if some solutions match my technology level.
Of course, your level of technology may differ.
Since I would like to maximize
interest in this subject, I will be using a rather subjective point of
view rather than the dry objective methods of most studies. If a
solution produces or saves useful quantities of power AND if it's affordable
AND if it can be maintained - I'll try to describe it in some detail.
Then, it is up to the reader to investigate further. If I clearly
don't succeed, you'll know that too - and perhaps save some time and effort
when you investigate your own future energy solutions. Peak oil will
create severe problems. But with these problems comes opportunity.
It is my hope that the seeds for solving the energy problems might be planted
now and grow to at least partial fruition before they are needed.
This site hopefully will be helpful in motivating people to pursue solutions
that work rather than just the ones that industry and government decide
to subsidize.
