In Agriculture
Energy Efficiency
As the agricultural sector accounts for less than 5% of Türkiye’s total energy consumption, it does not occupy as prominent a place in energy efficiency regulations as the transport, industry and residential sectors. However, with the rapid development of technology, energy consumption in the agricultural sector is increasing faster than the national economy.
In addition, animal waste, the use of nitrogen fertilisers, diesel consumption in tractors, and the use of electricity and heat in greenhouses and animal shelters also contribute to greenhouse gas emissions from the agricultural sector.
In this context, many countries have launched initiatives on energy efficiency in agriculture and invested in efficient practices and technologies.
Energy use in the agricultural sector can be considered under two headings, direct and indirect energy use, in both crop and livestock production.
- Using geothermal energy for soil improvement, drying agricultural products, heating soil in open agricultural areas, fish farming and mushroom production
- Using solar energy for applications such as greenhouse climate control, product drying and soil disinfection
- Using all suitable forms of agricultural waste to produce gas, including biogas, and electricity, thereby recovering a significant proportion of the energy used in production
- Using natural chambers formed in soft rock structures as cold storage facilities and minimising the electricity required for cooling
- Automating the management of heating, cooling, ventilation and lighting systems in large barns, sheepfolds and animal shelters, and considering passive solar systems, heat pump applications and rooftop solar panels
Electricity is used where irrigation is carried out through pumping. Even where water is conveyed naturally to agricultural production areas through gravity fed lines, fossil fuel or electric pumps may still be required to distribute it from the edge of the field across the land. In many applications, water must also be pumped from underground to the surface before irrigation can take place.
In Türkiye, which is experiencing water stress, groundwater levels have fallen in many basins in recent years, increasing well depths. Pumping water from greater depths can significantly increase electricity consumption. This results in higher electricity bills and input costs and reduces the profitability of agricultural production.
Although this is not a direct energy regulation, using drip irrigation systems instead of conventional irrigation systems makes it possible to reduce both water and electricity consumption.
Improving the energy efficiency of electrically powered or diesel powered pumps is another important measure that can be taken in irrigation. Initial steps include determining the required pump load, selecting appropriately sized pumps and, where necessary, equipping them with speed control devices or variable speed drives.
Pumps powered entirely by solar energy, or hybrid pumps supported by solar energy, can also deliver considerable energy savings, particularly in areas with high solar potential, such as the southern provinces.
- Selecting engine power according to actual needs and setting tyre pressure correctly
- Ensuring that the capacities of the transport vehicle and auxiliary equipment are compatible
- Distributing loads evenly
- Regularly monitoring oil and fuel consumption and carrying out periodic maintenance
Tractors with electronic infrastructure, including tractors using CAN bus protocols, equipment compatible with smart agricultural technologies and digital monitoring systems are also expected to support energy efficiency more broadly. Electric tractors are expected to become a more energy efficient option in the medium and long term.
