Switchgrass is nothing less than amazing!
BBC News reports on a new study, Grass biofuels ‘cut CO2 by 94%’.
|Producing biofuels from a fast-growing grass delivers vast savings of carbon dioxide emissions compared with petrol, a large-scale study has suggested.
A team of US researchers also found that switchgrass-derived ethanol produced 540% more energy than was required to manufacture the fuel.
One acre (0.4 hectares) of the grassland could, on average, deliver 320 gallons of bioethanol, they added.
This is good news for the United States in so many ways:
Fewer CO2 emissions – 94% is almost “carbon neutral”
540% EROEI – Growing “energy independence”
Better than corn and soy – Less need for harmful herbicides and pesticides, such as Atrazine
Native prairie grass – Improves local biodiversity
Plant once – Reduces erosion and farm fuel consumption
