Information is at our fingertips and all we have to do, as individuals and as a society, is reach out and grasp whatever we need. Why then are we continuously ignoring what is laid in plain sight, in the simplest of terms and sticking to our traditional ways when we need to change? It is as simple as that!
We need alternatives to the fuel we consume so rapidly. We have alternatives to both gasoline and petroleum diesel in the forms of ethanol and biodiesel. We have the technology to make these products and we can gain the education needed to encourage the use of these products in a very short time so that everyone knows the benefits and is willing to make the change.
In short, ethanol is a mixture of alcohol and gasoline and at gas stations the E85 mixture that is sold, means that there is 85% Ethanol Alcohol and only 25% gasoline. Some vehicles are being manufactured to run on pure alcohol, but not many as of yet. Typically, here in the United States, ethanol is derived from corn and therefore is a competitor for food. However in foreign countries, such as Sweden, it is made from bio-waste.
Biodiesel is similar in this aspect to ethanol. It can be derived from new or used ingredients. It is however different in that it is vegetable oil not alcohol. Uncooked or unused oil is typically easier to work with to produce biodiesel but it is more expensive and competes with food sources.
Meanwhile, used oil is harder to get but is better in that it is using a waste-product as fuel, is not competing with the production of crop quantities and many consumers are demanding that their biodiesel be from recycled sources.
At most gas/service stations the diesel that is sold is strictly Petroleum diesel and in some states, such as California, up to 5% biodiesel can be mixed with 95% diesel and it’s still be labeled as diesel. Most diesel-ran vehicles can run on biodiesel up to B20 (20% biodiesel, 80% diesel) without any alterations needed.
Biodiesel must be tested to meet government regulations in order to be commercially sold and must pass the ASTM D6751 test to meet diesel standards.
The economic market is that the subsidized products of gasoline and diesel are first, followed by ethanol, then biodiesel. Hydrogen as a fuel is still a long way in the future and is a product of a fuel, not its own source. Typically commercial biodiesel is the most expensive, while homemade is cheaper every time.
“Tax carbon. Fuel choice is a function of policy. We fight wars to keep gas prices low – that’s a policy decision.”
Estill has been making biodiesel since 2002. His first book entitled, Biodiesel Powers; the Passion, the People and the Politics of the Next Renewable Fuel, was released in 2005. He answers my question of what the future holds by predicting,
“Biodiesel will be made from oils that are currently wasted as more people realize its value and necessity.”
Another practicing professional of biodiesel manufacturing, Jamie Lutch of Simple Fuels, responded to my inquiries of what the future in fuel holds and how to get more people actively using alternative types by saying,
“Better education about what they [biofuels] are and their place in the modern energy economy.”
He agrees with Estill and emphasizes that to change the energy policy people must,
“Use and demand renewable fuels from the consumer end.”
Both of these companies discuss how they are unique in the industry by using locally recycled feedstock [waste-oil] and distributing that fuel back to their own local areas. This is compared to large oil companies that go world-wide to bring back needed resources of fuel.
They do encourage that people begin making their own biodiesel if capable. Estill responded,
“It’s a fabulous idea. It’s the best way possible to promote conservation.”
Lutch wasn’t as optimistic but replied,
“Some people can and should, others can’t and shouldn’t.”
