The Power Density of Ethanol from Brazilian Sugarcane
- Andrew R.B. FergusonAffiliated with
The power density of ethanol produced from sugarcane in Brazil is about 2.9 kW/ha. That is equivalent to capturing a little more than a thousandth part of solar radiation, and is also a little more than a thousandth part of the power density we are used to from oil and gas. So ineffective is 2.9 kW/ha, that about 5 million ha of land would have to be put down to sugarcane every year just to satisfy the increase in transportation energy demand that results from the annual expansion of population in the U.S.A.
