Renewable Energy, Solar Energy
Farmers switched from diesel to solar panels in Pakistan and started running irrigation pumps at a much lower cost. The relief on the wallet came quickly, especially for those who depended on expensive fuel or an unstable power grid to water their crops.
The information was published by Reuters, an international news agency with economic and environmental coverage, on October 2, 2025. The case shows an unexpected effect of solar energy in the field: the technology became more accessible, but it also facilitated the extraction of water hidden underground.
This water is called groundwater. It is stored below the soil and acts as a natural reserve. When many pumps draw this water for longer, the level can drop and put the field on alert.
Migrant workers left the world’s largest renewable energy park in India after extreme heat, 12-hour shifts, delayed wages, and poor accommodations at a site that still promises to supply 18 million homes.
Taiwanese fishermen accepted offshore wind turbines in the name of clean energy, but now they say that old routes have disappeared, fish have decreased, and income has become uncertain on the coast.
Europe wants to hold onto the black powder from used batteries because this dark residue contains valuable metals, can supply up to 1 million electric cars per year, and has become an industrial dispute.

The change appears in the routine of farmers like Karamat Ali, 61 years old, a rice producer in the Punjab province. He started using solar panels to operate a tube well, which is a system consisting of a well and a motorized pump to draw groundwater.
Previously, this type of irrigation relied more on diesel or grid electricity. With solar panels, the farmer can use sunlight to activate the pump and bring water to the crops.
In practice, irrigation becomes easier and cheaper. The producer spends less energy, has more freedom to water the crops, and reduces fuel dependency.
The problem arises exactly at this point. When pumping water becomes almost free, many farmers start irrigating for longer. What seems like a solution for the energy bill can turn into pressure on the groundwater reserve.
The advancement of solar pumps in the Pakistani countryside has gained scale. The country already had about 650,000 solar tube wells in 2025, a number that shows how solar energy has ceased to be a small alternative and has become part of rural irrigation.
These wells are important because they draw water from the underground. In agricultural regions, they help keep crops alive when surface water is not enough or when traditional irrigation does not meet the demand.
But the equation changes when thousands of pumps work for longer periods. An isolated farmer may not seem like a risk. Many wells operating simultaneously can lower the groundwater level in an entire region.
Therefore, the warning is not about the solar panels themselves. The central issue is the use of water without sufficient control, in a country where agriculture heavily depends on irrigation.
Rice is a crop that requires a lot of water. When irrigation becomes cheaper, planting rice can become more attractive for farmers seeking to improve production.
In Pakistan, rice areas grew 30% between 2023 and 2025. This growth increased the pressure on irrigation pumps and on the groundwater used to sustain the plantations.
Solar energy helped the farmer reduce expenses, but it also removed part of the natural limit imposed by the cost of diesel. If before the fuel weighed on the decision to irrigate, now the sun allows the pump to be activated with less immediate concern.
This is the point that draws attention: the same technology that reduces expenses can increase the consumption of a reserve that takes time to replenish.
Reuters, an international news agency with economic and environmental coverage, brought the central numbers about the pressure underground. Between 2020 and 2024, zones of severe groundwater depletion in parts of Punjab more than doubled in size.
Severe depletion means that water is getting lower in critical areas. For the farmer, this can mean less efficient wells, the need to seek water deeper, and greater risk for future production.
The alert is silent because groundwater does not appear on the surface. The field may seem productive for a while, while the reserve below the ground decreases.
When the problem appears strongly, recovery can be difficult. Rain and rivers can help replenish some of the water, but this process does not happen at the same speed as the withdrawal made by thousands of pumps.
The case of Pakistan does not place solar energy as an enemy of agriculture. Solar panels reduce costs, help rural producers, and can decrease dependence on expensive fuels.
The problem lies in water use. Without clear rules, sufficient measurement, and withdrawal control, the solar pump can function like an open tap over a reserve that is not infinite.
To understand simply, just imagine groundwater as a water tank hidden in the soil. If many people withdraw water every day and little water returns inside, at some point the level drops.
Therefore, the debate needs to unite clean energy and water management. The solar pump solves part of the cost, but it does not solve the natural limit of the underground reserve alone.
Solar energy entered the Pakistani field as an economic solution for farmers pressured by expensive diesel and unstable energy. The technology improved irrigation and made pumping more accessible.
At the same time, the expansion of rice crops and the increased use of solar tube wells have increased pressure on groundwater. The red alert arises from this combination of immediate economy and hidden environmental risk.
The lesson is clear: clean technology needs to go hand in hand with water use control. Without this, the economy in irrigation can demand a high price on the future of crops.
In Pakistan, the sun helped the farmer spend less, but also showed that the water underground needs to be treated as a limited resource, not as an endless reserve.
If solar energy makes irrigation cheaper, who should control the use of groundwater: the farmer, the government, or both together? Leave your opinion and share this discussion.
