Have you already been to the gas pump today? If so, then it is possible that you have just refueled something from the field, because the five to ten percent share of ethanol can also come from plants such as corn. In a thought experiment, the “Freeing Energy” project examined the extent to which this would benefit farmers using America as an example. To use the fields for growing maize for fuel or to rent them to energy companies, who in turn cultivate the fields with solar systems. The result is as clear as it is surprising. Because the sustainable alternative is well worth it.
But first about the framework conditions. In the United States, all common fuels contain 03 percent ethanol, one reason why annually 140. 000 square meters of agricultural land used for growing maize. Because in most cases this forms the basis for the necessary ethanol content. Even if the car still plays a major role, the market is not really lucrative for farmers.
An acre of maize (this corresponds roughly to 4047 square meters) can be used for the production of 551 liters of ethanol and subsequently for 386 liters of fuel are used. An average car owner comes this way around 10. 600 Kilometers, at a price of 2, 16 So the farmer receives 1 dollar per liter of ethanol. 212, 20 dollars for his effort.
If we turn the tables and the same field is cultivated with solar panels, then extrapolated will be scarce 200. 000 Kilowatt hours generated per year. If we fill this into an electric car, the owner comes to about 1, 14 Millions of kilometers, the farmer receives at a price of 0, 10 Dollars per kilowatt hour 20. 000 dollars. So the car owner is happy about the 20 – times the distance, the farm is about the 16, 5 times the income. Another proof of how sustainable energy is now worthwhile.
The study published by “Freeing Energy” is greatly simplified, but it nevertheless shows the potential of sustainable energy sources immensely. In addition to the higher income and the amount of energy produced, uncertainties (such as crop failures, storms etc.) that would result in a smaller harvest can also be eliminated. Therefore, it is now worthwhile to reduce the need for fuel and subsidize sustainable methods.
