Key Takeaways
- Diesel-powered tubewells and lift pumps have declined by 36% since 2004.
- Solar units now account for 52% of all farm irrigation power sources.
- Punjab leads the transition with solar powering 862,238 tubewells.
For more than half a century, diesel engines have been the primary source of power for Pakistani agriculture. However, this era is coming to an end as solar energy has replaced diesel in farm irrigation. According to the 7th Agricultural Census 2024 by the Pakistan Bureau of Statistics, the number of diesel-powered tubewells and lift pumps has fallen from 833,953 units in 2004 to 530,500 today, a decrease of 36%. Over this period, the total fleet of tubewells and lift pumps nearly doubled, increasing by 97% to 1.83 million units.
The shift towards solar power is significant. Solar-powered units did not appear in the 2004 machinery census but now account for a majority of farm irrigation systems. With 959,865 solar-powered tubewells and lift pumps, solar energy has become the single largest power source, making up 52% of all units.
Punjab province is at the forefront of this transition. Solar now powers 862,238 tubewells in Punjab against 331,059 running on diesel. In Sindh, solar tubewells outnumber diesel ones by a margin of 36,246 to 25,017.
While the shift towards solar is clear, diesel remains dominant in certain regions. In Balochistan, diesel still powers more than eight out of ten tubewells, with 123,495 units running on fuel compared to 151,394 total tubewells. Khyber Pakhtunkhwa also retains a majority of its tubewells powered by diesel, with 33,834 diesel-powered tubewells out of 61,063.
The transition from diesel to solar is driven by economic factors. Diesel pumps require daily fuel costs, whereas solar installations are one-time investments that provide free water pumping. As diesel prices have risen year after year, the financial advantage of solar has become increasingly apparent. The economics behind this shift underscore its significance for both farmers and the country’s energy landscape.
The quiet death of the diesel pump is a significant energy transition in Pakistan, cutting fuel import bills and shielding farmers from price shocks. It also lowers daily costs associated with growing food. However, it leaves some remote areas without reliable electricity, where diesel remains essential for deep wells in districts lacking grid access.
