KPMG in conjunction with Red C conducted this broad survey of Irish people and their attitudes to all elements of the energy transition.
Ireland’s energy transition featured prominently in national discourse throughout 2025, reflecting both landmark progress and rising challenges.
Major national milestones such as record solar PV and onshore wind generation were achieved, yet challenges persisted, such as extensive planning delays, grid capacity constraints, and surging power demand from electrification and data centre demand.
For the third year, our research analyses Irish attitudes to all elements of the energy transition. It explores public sentiment, behaviours, and barriers related to climate action, renewable energy, and the energy transition.
The findings present a nuanced picture. While strong majorities continue to support the development of renewable infrastructure and show willingness to adopt energy efficient behaviours, there is a subtle erosion in climate concern and rising scepticism about Ireland’s ability to meet its decarbonisation ambitions with rising awareness of the financial and delivery challenges of renewable infrastructure.
Mobilising people, government, and industry stakeholders will be vital, in addition to decisive political leadership to effectively communicate the benefits of the energy transition to Ireland’s energy security and independence.
