It's one of the findings of a new report which outlines what actions local authorities are taking to tackle climate change
This report from the Local Government Management Agency found 21 councils activated flood emergency response plans on 82 occasions between 2014 and 2018.
In this time, 101 million was spent on clean up, road repairs and disaster recovery.
In terms of energy efficiency, 20 local authorities spent a combined 120 million euro in projects from 2011 to 2017.
They claim 60 thousand tonnes of carbon dioxide was prevented through the various measures.
The report also says going forward, councils are committed to other measures such as more electric charging points.
They say its important better infrastructure for electric cars is vital if plans to ban the sale of new petrol or diesel cars by 2030 can be achieved.
