1. Introduction

Renewable energy has become an important component of modern agricultural development. Agriculture depends heavily on reliable energy for irrigation, groundwater pumping, crop processing, cold storage, dairy operations, mechanisation and transportation. Traditionally, many agricultural activities have depended on subsidised electricity or diesel, creating problems of high public expenditure, fossil-fuel consumption, groundwater depletion and rural energy insecurity.

Renewable-energy technologies—particularly solar pumps, solar-powered irrigation, biomass energy, biogas, solar dryers, solar cold storage and decentralised renewable-energy plants—can connect agricultural development with energy security and environmental sustainability.

In India, the most significant policy example is the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM). Its framework supports standalone solar agricultural pumps, solarisation of existing agricultural pumps, feeder-level solarisation and decentralised renewable-energy plants. The scheme also allows farmers, farmer groups, cooperatives, panchayats, FPOs and water-user associations to participate in renewable-energy generation. (PM-KUSUM Portal)

Thus, renewable energy in agricultural development is not merely an environmental policy. It involves land law, electricity regulation, water governance, agricultural policy, environmental law, subsidy regulation, contract law and rural development.

2. Meaning and Scope

Renewable energy in agriculture refers to the use of naturally replenishing energy resources for agricultural production and related rural activities.

Major applications include:

Solar irrigation pumps

Solar-powered farm machinery

Solar dryers for agricultural products

Solar-powered cold storage

Biomass-based electricity and heating

Biogas for farms and livestock operations

Small-scale wind and hybrid renewable systems

Renewable-energy-based food processing

Solar-powered groundwater pumping

Farmer-owned renewable-energy generation and electricity sale.

The legal framework must balance three objectives:

agricultural productivity;

energy and environmental sustainability; and

protection of farmers, land and natural resources.

3. Solar Irrigation and Agricultural Development

One of the clearest connections between renewable energy and agriculture is solar irrigation.

Under PM-KUSUM, farmers can receive financial assistance for standalone solar agricultural pumps. For grid-connected agricultural pumps, solarisation allows farmers to use solar electricity for irrigation and, subject to the scheme's conditions, sell surplus electricity to the distribution company. (Ministry of New and Renewable Energy)

This changes the economic structure of agricultural irrigation. Instead of continuously purchasing diesel or relying entirely on grid electricity, the farmer can use a renewable source whose operating cost is comparatively low after installation.

The legal significance is substantial because the farmer becomes not only an agricultural consumer but potentially a producer of electricity—or "prosumer."

4. PM-KUSUM and Farmer Participation

PM-KUSUM demonstrates how renewable-energy law can directly support agricultural development.

Its principal components include:

Component A

Farmers, groups of farmers, cooperatives, panchayats, FPOs and water-user associations may establish decentralised renewable-energy power plants. Electricity may be sold to DISCOMs at a tariff determined by the relevant State Electricity Regulatory Commission. (Ministry of New and Renewable Energy)

Component B

Standalone solar agricultural pumps can be installed in areas where grid electricity is unavailable. The scheme provides central financial assistance along with state support, subject to applicable guidelines. (Ministry of New and Renewable Energy)

Component C

Existing grid-connected agricultural pumps may be solarised. The farmer can use the electricity for irrigation and may sell surplus generation to the DISCOM under the applicable framework. Feeder-level solarisation is also contemplated. (Ministry of New and Renewable Energy)

This model potentially converts agricultural land from merely a place of consumption into a site for distributed renewable-energy production.

5. Agricultural Land and Renewable-Energy Projects

A major legal issue arises when agricultural land is used for solar-energy projects.

Agricultural land is ordinarily subject to land-use restrictions. Conversion from agricultural to non-agricultural use may require statutory permission.

The Karnataka High Court considered this issue in Sri S. Someshaiah v. M/S Ravindra Energy Ltd. (2022). The court examined Section 95(10) of the Karnataka Land Revenue Act and observed that the provision creates a legal mechanism whereby an occupant of agricultural land seeking diversion for solar-power generation under the Karnataka Solar Policy can obtain the benefit of deemed permission, subject to the statutory requirements. (Indian Kanoon)

The case illustrates an important principle: renewable-energy development does not automatically eliminate agricultural land-use regulation. Instead, legislation may create specialised mechanisms to facilitate renewable-energy projects while retaining regulatory control over land.

6. Judicial Treatment of Approvals for Solar Projects

The interaction between agricultural land and renewable-energy development also appears in electricity-regulatory litigation.

In Gujarat Urja Vikas Nigam Ltd. v. Gujarat Electricity Regulatory Commission (2014), the Appellate Tribunal for Electricity considered contractual and statutory approvals associated with a solar project. The case involved requirements concerning agricultural land, statutory permission and environmental/CRZ clearances. The tribunal recognised the importance of obtaining legally required approvals for development of renewable-energy projects. (Indian Kanoon)

The case demonstrates that renewable-energy projects remain subject to the broader legal framework governing land acquisition, land conversion, environmental approvals and regulatory permissions.

7. Renewable Energy and Water Governance

Solar pumps can substantially reduce the marginal cost of irrigation. However, this creates an important legal and environmental problem: cheap irrigation energy can encourage excessive groundwater extraction.

Consequently, renewable-energy policy cannot be separated from groundwater regulation.

A legal framework for solar agriculture should therefore consider:

groundwater extraction limits;

metering;

efficient irrigation;

drip and sprinkler systems;

crop diversification;

aquifer conditions;

water-user associations; and

incentives for conserving rather than merely extracting water.

The legal objective should be to ensure that replacing diesel or grid electricity with solar energy does not unintentionally accelerate groundwater depletion.

8. Renewable Energy and Farmers' Income

Renewable energy can create additional agricultural income.

Under the PM-KUSUM framework, farmers can potentially earn from electricity generated on their land. The framework also contemplates arrangements under which developers establish renewable-energy plants on farmers' land and the landowner receives lease rent. (Ministry of New and Renewable Energy)

This creates a new form of rural economic activity:

Agricultural land → renewable-energy infrastructure → electricity generation → electricity sale → additional rural income.

However, contracts must clearly address:

lease duration;

rent;

escalation;

land restoration;

liability for damage;

insurance;

termination;

access rights;

transmission infrastructure; and

responsibility for dismantling equipment.

9. Biomass and Agricultural Waste

Renewable energy in agricultural development is not limited to solar power.

Agricultural residues such as:

crop stalks,

husks,

bagasse,

animal waste, and

other organic residues

can be converted into energy.

Biogas plants can also provide energy while producing digestate that can potentially be used as an agricultural input.

The legal framework must regulate:

waste collection;

environmental standards;

emissions;

transportation;

plant safety;

electricity generation;

grid connection; and

ownership of agricultural residues.

Proper regulation can transform agricultural waste from an environmental problem into an energy resource.

10. Renewable Energy and Rural Infrastructure

Renewable energy can support agricultural infrastructure beyond irrigation.

Solar electricity can power:

cold-storage facilities;

milk chilling units;

grain dryers;

warehouses;

food-processing units;

water purification;

farm machinery; and

rural micro-enterprises.

This is particularly important where grid infrastructure is weak.

The legal framework should encourage decentralised energy systems while ensuring technical standards, consumer protection and electricity-safety requirements.

11. Contract Law and Renewable-Energy Agriculture

Agricultural renewable-energy projects frequently involve long-term contracts.

Examples include:

land leases;

power-purchase agreements;

equipment supply contracts;

operation and maintenance agreements;

financing agreements; and

agreements between farmers and developers.

Courts have therefore had to examine the relationship between contractual obligations and regulatory approvals.

For example, in JLT Energy (SAS) v. Hindustan Cleanenergy Ltd. (Delhi High Court, 2026), the court considered a solar-project contractual condition relating to conversion of agricultural land to non-agricultural use. The decision illustrates how land-use approval can become a significant contractual condition in renewable-energy project development. (Indian Kanoon)

This demonstrates the importance of conducting land and regulatory due diligence before financing or constructing a renewable-energy project.

12. Renewable Energy and Environmental Protection

Renewable energy is generally associated with environmental protection, but renewable projects themselves can create environmental impacts.

Large solar installations may involve:

land-use change;

biodiversity impacts;

drainage alteration;

habitat fragmentation;

transmission infrastructure; and

visual and ecological impacts.

Therefore, the principle of sustainable development requires renewable-energy expansion to be undertaken consistently with environmental safeguards.

Renewable energy should not be treated as automatically exempt from environmental law simply because it reduces carbon emissions.

13. Important Case Law

1. Sri S. Someshaiah v. M/S Ravindra Energy Ltd. (2022)

Issue: Conversion/diversion of agricultural land for solar-power generation.

Principle: The Karnataka statutory framework provided a mechanism for diversion of agricultural land for solar-power generation, demonstrating how land law can be adapted to facilitate renewable-energy development. (Indian Kanoon)

Significance: The case connects agricultural land regulation directly with renewable-energy development.

2. Gujarat Urja Vikas Nigam Ltd. v. Gujarat Electricity Regulatory Commission (2014)

Issue: Regulatory approvals and contractual requirements concerning a solar-energy project.

Principle: Renewable-energy projects remain subject to applicable statutory permissions and regulatory requirements, including those relating to land and environmental matters. (Indian Kanoon)

Significance: It demonstrates the importance of regulatory compliance in renewable-energy investment.

3. Sampelly Satyanarayan Rao v. Indian Renewable Energy Development Agency Ltd. (2016)

The Supreme Court considered issues concerning the financing of a renewable-energy project involving IREDA. The case illustrates the importance of financial and contractual regulation in renewable-energy development. (Indian Kanoon)

Its broader significance is that renewable-energy development requires not only environmental and electricity regulation but also enforceable financial and contractual structures.

14. Challenges

Despite its advantages, renewable energy in agriculture presents several challenges.

A. Groundwater depletion

Solar pumps can make irrigation inexpensive, potentially increasing groundwater extraction.

B. Land-use conflicts

Large solar projects can compete with agricultural and ecological land uses.

C. Financing

Farmers may lack sufficient capital to finance renewable-energy installations despite subsidies.

D. Grid integration

Large-scale distributed generation requires appropriate distribution infrastructure and metering.

E. Maintenance

Solar pumps and other renewable-energy systems require technical maintenance and replacement of components.

F. Contractual inequality

Small farmers may have weaker bargaining power when negotiating long-term land leases with commercial developers.

G. Regulatory fragmentation

Agricultural, electricity, land, water and environmental authorities may impose overlapping requirements.

15. Legal Principles for Sustainable Agricultural Renewable Energy

A comprehensive legal framework should incorporate the following principles:

Sustainable development

Inter-generational equity

Polluter-pays principle

Precautionary principle

Farmer participation

Fair compensation and transparent contracts

Groundwater conservation

Protection of agricultural productivity

Environmental impact assessment

Access to clean and affordable energy

The objective should not simply be to maximise renewable-energy capacity. It should be to create an integrated system in which energy security, agricultural productivity, farmer income and environmental protection reinforce one another.

16. Conclusion

Renewable energy is increasingly becoming a structural component of agricultural development. Solar irrigation, decentralised renewable-energy generation, biomass, biogas and renewable-powered agricultural infrastructure can reduce dependence on fossil fuels while improving energy access and potentially creating additional income for farmers.

India's PM-KUSUM framework illustrates this transition particularly clearly: farmers can receive support for solar pumps, solarise existing agricultural pumps and participate in decentralised renewable-energy generation. (PM-KUSUM Portal)

The case law demonstrates that this development operates within a broader legal architecture involving land conversion, environmental approvals, electricity regulation, contracts and project finance. S. Someshaiah demonstrates the importance of agricultural land-conversion law, while Gujarat Urja Vikas Nigam highlights the continuing importance of statutory approvals for solar projects. (Indian Kanoon)

Ultimately, the future of renewable energy in agriculture depends on an integrated legal approach. The law must encourage clean-energy investment while preventing groundwater depletion, protecting agricultural land, ensuring fair treatment of farmers and maintaining environmental safeguards. Properly designed, renewable-energy law can therefore become an important instrument for sustainable agricultural transformation and rural economic development.
