Calculating efficiency in terms of how much energy is available from the biofuel versus how much energy was in the sunlight hitting the plants used to produce the biofuel, the efficiency of ethanol made from corn is only about 0. But is there enough biomass? And therein lies the rub. Peak Phosphate will also cause civilization to collapse Industrial farming is also limited by phosphate, which scientists estimate will last from 40 to more years.

Phosphate is mined from phosphate rock. To do that would require 15 billion metric tons of plant biomass taking up billion cubic meters bcm. Although coal and oil took millions of years to form into dense, concentrated solar power, all we had to do was extract and transport them Odum With every step required to transform a fuel into energy, there is less and less energy yield. In the United States all green plants collectively produce biomass equivalent to about 53 exajoules of energy per year from sunlight, only about half of our total fossil energy use. But is there enough biomass? Nineteenth century western farmers converted their corn into whiskey to make a profit Rorabaugh Oil is a biofuel, but nonrenewable since it took Mother Nature millions of years to brew with , pounds of plants per gallon, which is equivalent to cramming 40 acres of wheat into your gas tank every 20 miles Dukes.

Then they collapse Montgomery But ethanol was a product in search of a market, so ADM spent three decades relentlessly lobbying for ethanol to be used in gasoline. Last update Oct 23, , first [ Formerly titled: The more work left to nature, the higher the energy yield, but the longer the time required. Archer Daniels Midland ADM , a large grain processor, came up with a similar scheme in the 20th century; ethanol. The energy to haul moonshine is a tiny fraction of the energy to haul corn to distant cities after all, more of a positive EROI if you will. And therein lies the rub. The idea was interesting — atomic jets could fly for months without refueling. Fuels made from biomass are a lot like the nuclear powered airplanes the Air Force tried to build from to , for billions of dollars. The Department of Energy lists ways biomass is already being used that will compete with its use as a fuel and for electricity generation Ruth Table 3. Ethanol is an agribusiness get-rich-quick scheme that will bankrupt our topsoil. Odum says that time explains why renewable energy provides such low energy yields compared to non-renewable fossil fuels. Peak Phosphate will also cause civilization to collapse Industrial farming is also limited by phosphate, which scientists estimate will last from 40 to more years. The Dirt on Dirt. Since trucks and rail are the basis of civilization as we know it, all, most of this biomass ought to be converted to 2 diesel to keep trucks and locomotives running.
