Who offers renewable energy in Ireland?

You can reduce your environmental impact by choosing a green energy plan. Here’s how renewable energy in Ireland works and how to switch to a greener tariff.

What is renewable energy?

Renewable energy comes from sources that are constantly replenished naturally or by a process such as the sun, wind and water.

Renewables, sometimes referred to as green energy, are sustainable and include solar energy, wind energy, hydropower and geothermal energy.

Unlike coal, oil, natural gas and peat, this type of energy produces zero carbon dioxide emissions when it is generated because no fossil fuels are used to create it.

How much of Ireland’s energy is renewable?

The development of renewable energy is a key focus of Ireland’s climate change strategy.

Ireland is committed to the goal of at least 16% of its energy coming from renewables by 2020. This target, known as the ‘overall renewable energy share (RES)’ target is a mandatory target under the EU Renewable Energy Directive (RED).

To date, the overall renewable energy share in Ireland was 13.5% of gross final consumption (GFC) meaning that Ireland has not met its overall RES target yet. Learn more at Sustainable Energy Authority of Ireland (SEAI).

Which suppliers offer renewable plans?

The Commission for Regulation of Utilities (CRU) requires that energy suppliers disclose the sources they use to generate their energy each year.

The latest CRU report Fuel Mix Disclosure 2021 reveals the energy suppliers in Ireland offering 100% renewable energy.

Suppliers of 100% renewable energy

Suppliers with a fuel mix of less than 100% renewable

Where a supplier has not declared their fuel mix by March 2022, or chose not to disclose, they’ve been assigned the Residual Mix figure of 21.3% renewable.

Supplier % Renewable  
Bord Gáis Energy 41.1%  
Community Power 39.8%  
Electric Ireland 65.3%  
Glowpower Not declared  
Prepay Power Not declared  
Water Power Not declared

Aside from switching to a green tariff, the next best way to help the environment is to reduce your energy consumption. Our top energy saving tips guide is full of helpful ideas to help you conserve energy in the home.

You can also get grants to make home improvements and make your home more energy-efficient although these will often cost you more money upfront.

Renewable energy FAQs

Are renewable energy tariffs more expensive?

No, not necessarily. In the past, renewable energy tariffs were more expensive, but things have changed due to more suppliers promoting their green credentials and better infrastructure.

You can still save on your energy bills if you switch from a standard tariff to a renewable energy plan.

What is the residual fuel mix?

The Residual Mix is calculated for Ireland, for Northern Ireland, and on an All-Island basis. It’s the mix of all unclaimed electricity in the system.

It’s the sum of:

  • Any generation attributes not assigned to a supplier
  • Surplus Guarantees of Origin declared by suppliers
  • Unused/cancelled certificates which expired in the disclosure period

What is sustainable energy?

Sustainable energy describes energy that is generated from an energy source that will never deplete, like solar, wind and tidal power.
