Corn as Biomass Electricity 22x More Efficient Than Ethanol

Cheap fossil fuel has allowed us to waste the majority of our energy, filling the planet with pollution and waste heat. Our car engines are only 25% efficient and coal power plants are not much better. Corn ethanol is one of the worst wastes of biomass: An acre of corn produces about 330 gallons/year if you cook it using fossil fuel.

Use the ethanol as a heat source and the net yield drops to 214 gallons/year. Car gas mileage is 30% lower with ethanol. At 25 miles/gallon we can only drive 25 X 214 = 5350 miles per year on an acre of corn.

If we take that same acre of corn and burn it to make electricity to charge an electric car, we will be able to drive the car 22 times as far! About 117,096 miles per year!
