This just makes you wonder why Switchgrass isn't higher on the list in the US for making Ethanol than corn is.
Switchgrass Yields Five Times More Energy Than is Used to Grow it
A new study by the University of Nebraska's Kenneth Vogel has shown that
switchgrass, a prairie grass found alongside the borders of many fields,
yields 540% more energy than is used to grow it.
******* SKIP ******
That impressive 540% figure compares quite favorably to the
93% return on soybean biodiesel and (measly) 25% return on corn ethanol. Emissions
produced from using switchgrass bioethanol would be
roughly 94% lower than those from gasoline - making it almost carbon neutral
Why these findings aren't in the headlines more or being talked about on the media more is beyond me (not really).
Here is an energy source that produces 540% more energy than it takes to grow and process it and is
ALMOST carbon neutral, and yet you hear
VERY little about it!
