DEFINITION OF FARM POWER. Farm power is an essential input in agriculture for timely field operations for increasing the production and productivity of the land. Farm power is used for operating different types of machinery like tillage, planting, plant protection, harvesting and threshing machinery, and other stationary jobs like operating irrigation equipment, …

The relatively dilute nature of wind and solar mean that harnessing them is very materials-intensive – many times that from energy-dense sources. Wind turbines have developed greatly in recent decades, solar photovoltaic technology is much more efficient, and there are improved prospects of harnessing the energy in tides and waves.

This mechanical operation consumes the energy, and size reduction is merely a result of this energy consumption. This viewpoint is reasonably valid for tumbling mills where energy input tends to be constant and the proportion of the energy that is usefully consumed in particle breakage is low (<10%).

Energy recovery. Energy recovery is a waste treatment process that generates energy in the form of electricity, heat or fuel. Energy recovery is a preferable waste handling process than sending to landfill. However, it should be considered as one of the last options at the end of life, after reuse, refurbishing and recycling.
