-Energy conersions always imply energy losses. Converting energy from one from into another is necessary for utilising energy. For instance, in lift irrigation:&nbsp;A diesel engine converts chemical energy of oil into mechanical energy for powering the shaft of a pump. This pump then converts shaft power into potential energy of water by&nbsp;bringing the water to a higher height. Energy conversion is also necessary for energy generation: A solar&nbsp;PV cell generates energy by converting radiation energy into electricity. Within the conversion a share of energy is lost. This leads to the concept of [[Energy Efficiency Introduction|energy effifiency]].<ref>GIZ, Energy Efficiency. http://www.giz.de/expertise/html/13356.html</ref><br/>

 Energy efficiency can lead to ecological and economic win-win situations. Lower costs for industry increase both competitiveness and job security. Also private households benefit, an impact that particularly benefits the poorer segments of a community, who frequently spend a disproportionately large portion of their income on energy. Further, everyone benefits from the positive effects on the climate and environment that result from lower greenhouse gas emissions and the reduced consumption of natural resources ([http://www.giz.de/expertise/html/13356.html GIZ, Energy Efficiency]).<br/>
-Energy efficiency measures must target areas where energy is actually “consumed”: energy production, transmission and distribution, buildings, industry, private households, municipal facilities, and the transport sector. One key sector is the agriculture and food sector, which consumes about 30% of the global energy<ref name="FAO, 2011: “Energy-smart” food for people and climate – Issue Paper: http://www.fao.org/docrep/014/i2454e/i2454e00.pdf">FAO, 2011: “Energy-smart” food for people and climate – Issue Paper: http://www.fao.org/docrep/014/i2454e/i2454e00.pdf </ref>.
