Energy ratios in Finnish agricultural production

Energy intensity ratios as net energy measures of United States energy production and expenditures

In this letter I compare two measures of energy quality, energy return on energy invested (EROI) and energy intensity ratio (EIR) for the fossil fuel consumption and production of the United States. All other characteristics being equal, a fuel or energy system with a higher EROI or EIR is of better quality because more energy is provided to society. I define and calculate the EIR for oil, natu...

Agricultural Production

Agricultural production is not keeping up with the world demand for food because the human population is increasing faster than agriculture’s food production capability (Pimentel et al., 1999). Uneven distribution of food, the inability of the poor to purchase food, and political unrest also threaten world food security for human society. Currently, more than 3 billion humans worldwide are maln...
