Wind energy has the potential to supply electricity across the world. Unlike other sources of electricity that require fuel in processing plants, wind energy generates electricity through wind, which is free from emissions.

Turbines can be used to generate electricity from wind. By harnessing wind energy, farmers can often cover all their energy and create a surplus that can be injected into the grid. 

Why should farmers consider on-farm wind energy?

Wind energy has negligible adverse effects on the environment as wind turbines do not emit carbon or other air pollutants and do not require water for cooling.

The following video provides general facts about renewable energy in Ireland.

What are the considerations for wind power development?

The following considerations should be taken into account for wind energy development on a farm.

  • The turbine must not be attached to a building
  • Only one turbine per site.
  • Total height must not exceed 20m and roto diameter must not exceed 8m
  • A 3m minimum clearance is required between the ground and the lowest point of the blades.
  • Noise levels must not exceed 43db(A) at the nearest inhabited dwelling.

Economic and Environmental Benefits

The economic benefits and emission reduction of investing in a wind turbine for a typical 93-cow herd are summarised in the Table below.

Research at Farm Zero C

At FZC, a holistic approach to farm energy is being used which includes the use of renewable energy and efficient use of energy on the farm. The farm uses a 15kW power wind turbine combined with a 15kW PV system. The objective is for the farm to have all energy coming from renewable sources.

Other Research

Key findings  from previous research on wind energy include:

  •  To help farmers decide on potential farm technologies for energy, a collaboration between Teagasc, the Sustainable Energy Authority of Ireland (SEAI), and the Cork Institute of Technology developed the National Agricultural Energy Optimisation Tool.
  • Wind generation has the potential to displace more expensive sources such as gas or coal-fired power stations or imports, reducing prices in the market (KPMG, 2021).
  • The deployment of wind generation in Ireland avoided 33 million tonnes of power sector CO2 emissions between 2000 and 2020 ( SEAI, 2021).
