How to cut our dependence on fossil fuels rapidly

A blog co-authored by MaREI’s Hannah Daly, Professor in Sustainable Energy at University College Cork and Jim Scheer, Head of Data and Insights at SEAI for the SEAI’s website states ‘We must all rally around the “Big 5” measures that take us 90% of the way to our 2030 obligations.’ 

Ireland is one Europe’s most fossil fuel dependent countries, a dependence that is making us less healthy, more vulnerable, and less prosperous. It is driving dangerous climate change that threatens us all. To make our energy sustainable and to reduce emissions, focussing on the most impactful solutions is more urgent than ever. The latest data and projections of greenhouse gases make it clear that Ireland is on course to breach legally binding national and international obligations unless we make a significant course correction. 

But with the myriad options available to move us away from fossil fuels, which will deliver the greatest impact, and which are likely to remain targeted niche solutions?

Just five key measures could deliver 90% of the greenhouse gas emission savings required for energy by 2030, according to Ireland’s Climate Action Plan. These “Big 5” measures are essential, no-regrets strategies. And the good news is that they are already available and well-tested, and can make our energy cleaner, more secure and more affordable.

So, what are the “Big 5”? 
  1. Wind, solar and grid 
  2. Electrify transport 
  3. Reduce unnecessary car use 
  4. Retrofit, heat pumps and district heat 
  5. Decarbonise industry
