Nuclear energy is a distant prospect – wind and solar are here now

Sceptics don’t outright deny climate change but dismiss solutions as unrealistic

Sadhbh O’Neill, Irish Times 26th Feb 2026

Recent commentary on Ireland’s energy system is a reminder that not everyone is comfortable with change.

For people unconvinced by the potential of renewable energy to provide all our energy needs, the focus of energy policy should still be on large-scale sources of generation, as it was in the glory days of the ESB when it ran everything (and it took up to 18 months to get a grid connection).

Amid nostalgia for a simpler past, there are still voices making the case that fossil fuels and nuclear energy should form the backbone of the grid. This case is made on the basis that renewables can only match demand up to a certain point due to their intermittency, low energy densities and the challenges of integrating them into the grid.

And it is always hard to make the case for energy efficiency and demand management when fossil fuels, on paper at least, are plentiful, and there is no sign yet of the big energy producers slowing down extraction or divesting from fossil energy………………………………………………..

With regard to nuclear energy, there is a lot of interest in small modular reactors (SMRs), which, at approximately 400MW generating capacity, would be much more appropriate in scale for Irish electricity needs. The problem with nuclear energy is that traditional power plants, at about 1.3GW, are too individually large for Ireland, not to mention the likelihood of a nuclear plant taking decades to secure the required approvals and get built.

The ESB in its 2025 Emerging Technology Insights report notes that SMRs remain unproven due to a lack of demonstration projects. None of the SMR projects to date will have a demonstration plant completed before 2030.

Given that we are just four years away from key climate deadlines, nuclear power is so unrealistic in the context of what we need to do right now that it might as well be irrelevant.

The SEAI Energy in Ireland 2025 report highlights that Ireland needs proven, immediate solutions to avoid missing its second carbon budget (2026–2030). Luckily for Ireland, we have abundant renewable resources, which have never been so cheap to develop.

Renewable energy costs have come down so fast and by so much that even when you factor in the grid upgrades required, in 90 per cent of the world they outcompete new fossil fuel infrastructure easily, including the US. This is because wind and solar technologies are proven, scalable and cost-competitive over the long run, making them more attractive to investors…………………………………………. https://www.irishtimes.com/environment/climate-crisis/2026/02/26/nuclear-energy-is-a-distant-prospect-wind-and-solar-are-here-now/
