Renewable Energy
What is Renewable Energy?
Renewable energy is energy generated from naturally replenishing resources such as sunlight, wind, water, biomass and geothermal heat, which are not depleted when used.
In agriculture, renewable energy refers specifically to on-farm or rural energy systems that harness natural processes or biological materials to produce sustainable power while reducing reliance on fossil fuels.
Unlike coal, oil or natural gas, renewable energy sources regenerate continuously and produce significantly lower greenhouse gas emissions.
Within farming and agribusiness, renewable energy plays a central role in achieving decarbonisation, energy security and diversified farm income.
Types of Renewable Energy in Agriculture
Agriculture contributes to and benefits from several forms of renewable energy:
1. Bioenergy
Energy derived from organic materials such as crop residues, manure and food waste.
Includes:
Biogas
Biomethane
Biofuels
2. Solar Energy
Photovoltaic (PV) panels installed on farm buildings or land to generate electricity.
3. Wind Energy
Onshore wind turbines located on agricultural land.
4. Hydropower
Small-scale hydro systems using flowing water on rural estates.
5. Biomass
Combustion of organic material (e.g. woodchip, crop waste) for heat and power.
Why Renewable Energy Matters in Agriculture
Climate Change Mitigation - Reduces greenhouse gas emissions and supports Net Zero commitments.
Energy Independence- Farms can generate their own electricity and reduce energy costs.
Income Diversification - Energy export to the grid creates new revenue streams.
Circular Economy - Converts agricultural waste into valuable energy resources.
Policy Alignment - Supports UK, EU and global renewable energy targets.
Renewable Energy in the UK
The UK agricultural sector plays a significant role in renewable energy production, particularly through:
UK policy drivers include:
Agriculture is increasingly recognised as both a food producer and an energy producer.
Net Zero 2050 targets
Renewable energy incentives
Environmental Land Management (ELM) schemes
Sustainable Farming Incentive (SFI) frameworks
Farm-based anaerobic digestion
Biomethane grid injection
Solar installations on farm buildings
Onshore wind projects
Biomass heating systems
Renewable Energy in Europe, USA & Globally
Europe
The European Union promotes renewable energy under the Renewable Energy Directive and Green Deal strategy, with strong investment in agricultural biogas and solar expansion.
United States
The USDA supports rural renewable energy projects through funding programmes such as the Rural Energy for America Program (REAP). Renewable natural gas and solar installations are rapidly expanding in US agriculture.
Global
Organisations such as the International Renewable Energy Agency (IRENA), FAO and World Bank promote renewable energy as essential to climate resilience, rural development and food system sustainability.
Renewable Energy vs Fossil Fuels
Feature | Renewable Energy | Fossil Fuels |
|---|---|---|
Resource Source | Naturally replenishing | Finite underground reserves |
Carbon Emissions | Low / near-neutral | High |
Sustainability | Long-term | Depleting |
Agricultural Role | Waste-to-energy, solar, wind | Traditional fuel dependency |
Climate Impact | Supports Net Zero | Drives climate change |
Renewable energy regenerates.
Fossil fuels deplete.
Renewable Energy vs Low-Carbon Energy
Feature | Renewable Energy | Low-Carbon Energy |
|---|---|---|
Source | Naturally replenishing | May include non-renewable sources |
Examples | Solar, wind, biogas | Nuclear, renewables |
Sustainability | Inherently renewable | Low emissions but not always renewable |
All renewable energy is low-carbon.
Not all low-carbon energy is renewable.

Frequently Asked Questions (FAQs) on Renewable Energy
What is renewable energy in simple terms?
Renewable energy is energy produced from natural sources that are continuously replenished, such as sunlight, wind and organic waste.
How does agriculture produce renewable energy?
Farms produce renewable energy through anaerobic digestion, solar panels, wind turbines and biomass systems.
Is renewable energy important for farming?
Yes. It reduces energy costs, lowers emissions and creates additional income opportunities.
What is the difference between renewable energy and green energy?
Renewable energy comes from replenishable sources. Green energy typically refers to renewable sources with minimal environmental impact.
Can farms become energy self-sufficient?
Many farms now generate enough renewable energy to meet their own needs and export surplus electricity or gas to the grid.
Does renewable energy help achieve Net Zero?
Yes. Renewable energy reduces fossil fuel dependence and lowers greenhouse gas emissions, supporting national and global Net Zero targets.
