With the price of traditional fuel rising faster everyday, people everywhere are looking for alternatives. Electric cars were once touted as the way to save the environment and beat the cost of gasoline, but they are so expensive that very few people can afford to save money by purchasing one.

Alternative fuels have long been discussed as a way to cut fuel prices and help the environment, but with the specialized engines they require, and their inability to pass the regulation tests required by the EPA, they have been a disappointment. The more solutions that are offered to the problem of high fuel costs and dangerous emissions, the further it seems we are from a solution…until now.

There is a fuel alternative that is all that it has promised to be and more. Biodiesel is not only cost effective it is environmentally friendly, as well. Biodiesel is completely biodegradable and made from renewable resources. That means that when you use biodiesel to power the engine of your car you aren’t robbing the earth of the riches meant for your grandchildren to enjoy.

Unlike the previous vegetable oil based fuels that can only be used in modified, specially made combustion- ignition engines, biodiesel can be used in its basic form to power the everyday diesel engines on the market today. That means that a simple to make batch of biodiesel could be used to power the family car on its daily errands.

Biodiesel is registered with the EPA as a legal motor fuel meaning that it can be sold and distributed just like the gasoline you pump into your car at the gas station. Unlike traditional gasoline, biodiesel isn’t as widely available for the average consumer. It can be purchased directly from distributors and manufactures and it is sold a few select stations around the country. If you are interested in trying biodiesel in your car, your best chance of finding it is to make it yourself.

The process is surprisingly easy and the ingredients are readily available. By simply mixing lye, alcohol, and vegetable oil in the right amounts, you can great biodiesel. This economical alternative fuel is made through the simple chemical process of transesterification. During this process, the glycerin is removed from fat or vegetable oil. The process naturally leaves behind byproducts, including methyl esters, which is the chemical name for biodiesel, and glycerin, commonly used in soap production. Biodiesel is completely free of sulfur and aromatics, something that can’t be said about traditional fuels.

Batches of biodiesel can be mixed up in small or large sizes and if done effectively will end up costing about seventy cents a gallon.

Anita Van Wyk asked:


Many of us know that solar energy is good, but few really
understand why.
Therefore, I compiled a comprehensive list of solar energy
advantages and disadvantages that will enable you to make an
educated decision whether on not Solar Power is right for YOU.

Solar Energy Advantages
1. Saves you money

After the initial investment has been recovered, the
energy from the sun is practically FREE. The recovery/
payback period for this investment can be very short depending
on how much electricity your household uses. Financial
incentives are available form the government that will reduce
your cost. If your system produce more energy than you
use, your utility company can buy it from you, building up a
credit on your account! This is called net metering. It
will save you money on your electricity bill if you have one at
all. Solar energy does not require any fuel.

It’s not affected by the supply and demand of fuel and is
therefore not subjected to the ever-increasing price of
gasoline. The savings are immediate and for many years
to come. The use of solar energy indirectly reduces
health costs.

2. Environmentally friendly

Solar Energy is clean, renewable (unlike gas, oil and
coal) and sustainable, helping to protect our environment.
It does not pollute our air by releasing carbon dioxide,
nitrogen oxide, sulphur dioxide or mercury into the atmosphere
like many traditional forms of electrical generations does.
Therefore Solar Energy does not contribute to global
warming, acid rain or smog. It actively contributes to
the decrease of harmful green house gas emissions. It’s
generated where it is needed. By not using any fuel,
Solar Energy does not contribute to the cost and problems of the
recovery and transportation of fuel or the storage of
radioactive waste.

3. Independent/ semi-independent

Solar Energy can be utilized to offset utility-supplied
energy consumption. It does not only reduce your electricity
bill, but will also continue to supply your home/ business with
electricity in the event of a power outage. A Solar
Energy system can operate entirely independent, not requiring a
connection to a power or gas grid at all. Systems can therefore
be installed in remote locations (like holiday log cabins),
making it more practical and cost-effective than the supply of
utility electricity to a new site. The use of Solar
Energy reduces our dependence on foreign and/or centralized
sources of energy, influenced by natural disasters or
international events and so contributes to a sustainable
future. Solar Energy supports local job and wealth
creation, fuelling local economies.

4. Low/ no maintenance

Solar Energy systems are virtually maintenance free and
will last for decades. Once installed, there are no
recurring costs. They operate silently, have no moving
parts, do not release offensive smells and do not require you to
add any fuel. More solar panels can easily be added in
the future when your family’s needs grow.

Solar Energy Disadvantages

The initial cost is the main disadvantage of installing
a solar energy system, largely because of the high cost of the
semi-conducting materials used in building one. The
cost of solar energy is also high compared to non-renewable
utility-supplied electricity. As energy shortages are becoming
more common, solar energy is becoming more
price-competitive. Solar panels require quite a large
area for installation to achieve a good level of
efficiency. The efficiency of the system also relies on
the location of the sun, although this problem can be overcome
with the installation of certain components. The
production of solar energy is influenced by the presence of
clouds or pollution in the air. Similarly, no solar
energy will be produced during nighttime although a battery
backup system and/or net metering will solve this problem. See
www.dsireusa.org for details on how net metering allows you to
save electricity and money. As far as solar powered
cars go – their slower speed might not appeal to everyone caught
up in today’s rat race.
