Ireland’s energy landscape is at a crossroads, with progress accelerating in some areas while challenges remain in others. SEAI’s Energy in Ireland 2024 Report paints a picture of a nation making strides in renewable energy deployment, but facing critical obstacles that demand immediate and bold action. For solar energy in particular, the opportunities to lead the charge are immense.
Milestones in Renewable Energy
2023 was a landmark year for Ireland’s energy transition. Key achievements included:
Solar’s Breakthrough Moment: Solar energy saw a 335% increase in generation, with utility-scale solar farms driving this growth. For the first time, large-scale solar farms produced more electricity than all rooftop installations combined. Solar photovoltaic (PV) now plays a vital role in balancing Ireland’s renewable energy mix, complementing wind generation during the sunnier months.
Record Renewable Contributions: Renewables accounted for 14.1% of primary energy, the highest proportion to date. Wind remained dominant, generating 11.7 TWh, while solar PV rapidly expanded.
Electricity Emission Reductions: A 22% decrease in electricity-related emissions highlights the growing impact of renewables and the benefit of low-carbon electricity imports.
Challenges in the Transition
While these achievements are noteworthy, the report underscores persistent hurdles:
Fossil Fuel Dependency: Despite renewable progress, fossil fuels still account for 82.7% of Ireland’s energy. Transport and heat sectors remain especially reliant, with 94% of transport energy coming from fossil sources.
Growing Demand on the Grid: Electricity demand rose by 4.1% in 2023, driven primarily by commercial services and data centres, which now consume over 20% of all electricity.
Grid Infrastructure Limitations: Ireland’s grid infrastructure is increasingly strained, unable to keep pace with the rising contribution of renewables, particularly solar and wind. This limits the capacity for further renewable integration and hampers the potential of microgeneration from rooftop solar.
Why Solar is Ireland’s Brightest Opportunity
Solar energy is emerging as one of Ireland’s most promising renewable solutions. In addition to its rapid growth, solar offers unique benefits:
Balancing Seasonal Generation: Solar PV generates the most electricity during summer, complementing wind energy, which peaks in winter. This seasonal synergy reduces reliance on fossil fuels year-round.
Unlocking Rooftop Potential: Rooftop solar installations represent an untapped opportunity for households and businesses to contribute to the clean energy mix while reducing their energy costs.
Enhancing Energy Independence: By diversifying energy sources, solar reduces dependence on imported fuels, ensuring a more secure energy future.
However, unlocking solar energy’s full potential requires targeted actions, including grid upgrades, streamlined permitting processes for solar farms, and expanded supports for rooftop installations.
The Path Forward: What Needs to Change
As we approach the end of Ireland’s first national carbon budget (2021–2025), there is no time to waste. SEAI’s report highlights three critical priorities:
Invest in Grid Infrastructure: The grid must be modernised and expanded to handle increased renewable generation, especially from solar and wind. Enhanced interconnection and storage solutions are essential to balance supply and demand, reduce curtailment, and maximise renewable integration.
Scale Up Solar Energy Deployment: From utility-scale solar farms to rooftop PV systems, Ireland must continue to accelerate solar adoption. Introducing new incentives and streamlining processes will help solar reach its full potential.
Empower Energy Consumers: Expand support for microgeneration and solar panel adoption for homes, businesses, and farms. With the right policies, Ireland’s citizens can become active participants in the energy transition.
Why 2025 is a Turning Point
2025 has the potential to be a defining year in Ireland’s energy journey. Decisive action now will set the stage for meeting 2030 goals, including a renewable energy share of 43%, and achieving sectoral emission ceilings.
Solar energy has the power to tip the balance. By integrating solar more effectively, supported by a robust grid and proactive policies, Ireland can lead the way in sustainable energy.
A Collaborative Effort
The transition to renewable energy is a shared responsibility. Ireland has the technology and resources to succeed, but it will take collaboration from individuals, businesses, and policymakers to make it happen. Whether it’s adopting rooftop solar, advocating for better energy policies, or investing in renewable technologies, every action counts.
Let’s make 2025 the tipping point for solar energy in Ireland. Together, we can power a cleaner, greener future.
