Document Summary
Modern agriculture is getting more and more productive at getting the most out of one hectare of land. We are currently able to supply everyone with food, a success on its own. Takes 8 kg"s of feed to produce 1 kg of beef, 4 kg"s to produce 1 kg of pork, 2. 5 kg"s to produce 1 kg of chicken or eggs. Net energy = total amount of high quality energy available from a resource minus the energy needed to find, extract, process, and get the energy to the consumer. Solar energy: directly or indirectly through wind, hydropower. Commercial energy: most comes from nonrenewable energy resources ex fossil fuels.
