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 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 . Keywords Brazil sugarcane ethanol power density Introduction In an eleven page paper Sugarcane and Energy the relationship between sugarcane and energy has been covered in considerable detail Ferguson 1999 however it may be useful to make available a more concise summary of this essential question what is the power density of ethanol from sugarcane The question needs to be asked since one great .
