Biofuel Myths vs Facts

department of energy ethanol renewable fuelsU.S. energy consumption is expected to grow 50% percent by 2030 and biofuels must continue to play a significant role to diversify our nation’'s energy sources.

As biofuel critics look to derail the efforts for developing renewable fuels, the US Department of Energy has prepared a new fact sheet that dispels a number of myths that keep being repeated. The full report is available online HERE (pdf).

MYTH: In terms of emissions, biofuels emit the same amount as gasoline or more.
greenhouse emissions gasoline ethanol
FACT: Biofuels burn cleaner than gasoline, resulting in fewer greenhouse gas emissions, and are fully biodegradable, unlike some fuel additives.

MYTH: Ethanol cannot be produced from corn in large enough quantities to make a real difference without disrupting food and feed supplies.

FACT: Corn-based ethanol is only one source of biofuel. As we address the technical hurdles associated with the efficient and cost-effective production of biofuels, ethanol will increasingly play a more significant role.

MYTH: Ethanol gasoline blends can lower fuel economy and may harm your engine.

FACT: Ethanol blends in use today have little impact on fuel economy or vehicle performance.
ethanol energy balance
MYTH: More energy goes into producing ethanol than it delivers as a fuel.

FACT: Each gallon of corn ethanol today delivers as much as 67% more energy than is used to produce it.

Great site! It's always good to get the straight scoop on biofuels. I've added you to my blogroll, check my blog out if you have time. I cover a wide range of topics; but oil, biofuels and agriculture are main staples.
