Pakistan heavily relies on agriculture, which accounts for 18% of its GDP and employs 42% of its labour force (World Bank, 2021). However, the agricultural sector is facing multiple challenges due to climate change, water scarcity, and energy crises (Malik et al., 2021). Frequent power outages have caused immense damage to the country's economy and created a barrier to sustainable agriculture (World Bank, 2021). To overcome the energy shortage, reduce carbon emissions, and mitigate climate change, Pakistan needs alternative sources of energy (Khan et al., 2021).

Green energy, which refers to renewable sources of energy that are environmentally friendly and sustainable, is an emerging solution to the energy crisis and can play a vital role in promoting sustainable agriculture (Renewable Energy Policy Network for the 21st Century [REN21], 2021). Solar and wind are the two main sources of green energy in Pakistan, with a solar potential of up to 2.9 million MW and an estimated wind potential of 50,000 MW (Khan et al., 2021). However, the utilization of green energy in Pakistan is still in its infancy (Khan et al., 2021).

The agriculture sector is responsible for 20% of Pakistan's total greenhouse gas emissions, making it one of the major contributors to carbon emissions in the country (Ministry of Climate Change Pakistan, 2021). The adoption of green energy in agriculture can reduce carbon emissions, mitigate climate change, and improve the energy security of the country (REN21, 2021).

To promote green energy adoption in the agriculture sector, the Pakistani government has taken several initiatives such as the Alternative Energy Development Board (AEDB) and the National Energy Efficiency and Conservation Authority (NEECA) (Khan et al., 2021). However, there is still a need for more efforts to accelerate the adoption of green energy in agriculture (Khan et al., 2021).

Sustainable agriculture, which refers to the production of agricultural products using techniques that protect the environment, public health, human communities, and animal welfare, can be promoted by the use of green energy in agriculture (Food and Agriculture Organization of the United Nations, 2021). The adoption of green energy can reduce the carbon footprint of the sector, improve energy efficiency, and provide farmers with a reliable source of energy while reducing energy costs (REN21, 2021).

This research article aims to explore the potential of green energy in promoting sustainable agriculture in Pakistan. It will examine the challenges in the adoption of green energy in agriculture, the policies required to promote its utilization, and the impact of green energy on sustainable agriculture.

Sustainable agriculture is an approach to agriculture that seeks to meet the needs of the present generation without compromising the ability of future generations to meet their needs (Pretty, 2018). One of the essential components of sustainable agriculture is the use of renewable energy sources, commonly known as green energy. Green energy is defined as energy that is generated from renewable sources, such as wind, solar, hydro, and geothermal energy, which are environmentally friendly and have low carbon emissions (Bakr et al., 2020).

Green energy transition for sustainable agriculture is based on the concept of energy justice, which is the idea that access to energy should be equitable and sustainable and that energy policies should promote social and environmental justice (Sovacool, 2021). This concept recognizes that access to energy is a fundamental human right and that access to energy services is critical for economic development, poverty reduction, and social well-being (IEA, 2021).

As the world becomes increasingly aware of the impact of climate change, the need for sustainable energy sources has become more pressing. In recent years, researchers have turned their attention to the use of renewable energy in agriculture, recognizing its potential to reduce greenhouse gas emissions and energy costs. In a literature review conducted by Parida, Iniyan, and Goic in 2011, the authors provided an overview of the various renewable energy sources that can be used in agriculture. They discussed the benefits of using renewable energy, as well as the challenges associated with its implementation.

Solar energy, in particular, has shown great promise in the agricultural sector. In a review conducted by Pathak and Solanki in 2018, the authors explored the potential of solar energy in agriculture. They discussed its various applications, such as crop drying, water pumping, and greenhouse heating, and the benefits of using solar energy, such as reducing dependence on fossil fuels and improving energy efficiency.

Wind energy has also been identified as a promising source of renewable energy in agriculture. Chen and Blaabjerg conducted a review in 2014, discussing the benefits of using wind turbines to generate electricity. They noted that wind energy can help reduce energy costs and increase energy independence, although challenges such as variability in wind speed and lack of funding must be addressed.

Biomass energy, which involves the use of crop residues and animal waste as an energy source, has also been explored as a potential source of renewable energy in agriculture. Pandey and Ramesh conducted a review in 2016, highlighting the benefits of using biomass energy, such as reducing greenhouse gas emissions and improving soil fertility.

Hydropower and geothermal energy have also been identified as potential sources of renewable energy in agriculture. Sahoo and Chandel explored the potential of hydropower in agriculture in a review conducted in 2017, while Y?ld?r?m and Çal??kan discussed the potential of geothermal energy in agriculture in a review conducted in 2019. Both reviews highlighted the benefits of using these sources of energy, as well as the challenges associated with their implementation.

Finally, in a review conducted by Bahri and Movahedi in 2017, the authors discussed the importance of energy efficiency in agriculture. They explored various technologies and practices that can be used to improve energy efficiency on farms, such as precision agriculture and renewable energy systems.

Overall, these reviews highlight the potential for renewable energy to transform the agricultural sector, reducing greenhouse gas emissions, and improving energy efficiency. However, the challenges associated with their implementation must be addressed if we are to achieve a sustainable future.
