What is energy efficiency & conservation?

Energy efficiency and conservation are irreplaceable in sustainable farming. Efficiency refers to the efficient use of consumed energy, while conservation to the reduction of total energy usage. By energy, we mean mainly the electricity used by devices and machines and the fossil fuels used for engines and heating.

Farmers use energy on the field while operating tractors, pumps, combines, and in the barn to power grain driers, silos, etc. Livestock farming requires energy to power the dairy equipment and provide heat/cooling for the animals and lighting.

For energy conservation, farmers may reduce the unnecessary use of the equipment and operate according to the manufacturers. For example, a tractor’s engine is more efficient in a specific rev range. In addition, keeping the engine running at idle consumes redundant energy. Farmers, to achieve energy efficiency, may invest in new equipment. Replacing old gasoline or diesel engines with new technology engines would limit fuel consumption.
