I hate to tell you, you are wrong but you are wrong.
Brazil is a great climate for growing Sugar Cane.
However, temperate regions are still very productive, note that the American Midwest is one of the bread baskets of the world. You over look the fact that biomass, such as corn stover (Stalks, Cobs, Shucks), Newspapers, wood waste, straw (wheat, grass, rice, etc.) can be converted to sugars through a relatively cheap process using sulphuric acid or specially manufactured enzymes.
The following table gives alcohol yield per ton of and per acre of several different crops.
Alcohol Yield per ton
Material Gallons Wheat..........85.0 Corn ..........84.0 Buckwheat......83.4 Raisins........81.4 Grain Sorghum..79.5 Rice rough.....79.5 Barley.........79.2 Dates, Dry.....79.0 Rye............78.8 Prunes, dry....72.0 Molasses.......70.4 Sorghum cane...70.4 Oats...........63.6

Dried biomass has a heating value of 5000-8000 Btu/lb. with virtually no ash or sulfur produced during combustion. About 6% of contiguous United States land area put into cultivation for biomass could supply all current demands for oil and gas. And this production would not add any net carbon dioxide to the atmosphere.[2]
One ton of dry biomass such as newsprint, dry wood, straw, nut shells, etc. yields about 100 gallons of ethanol.
Utilization of timber, farm and municipal waste products can more than supply the US with enough ethanol to replace all petroleum used in the US. r |
