Total energy consumption fell by 8.8%.
There was a sharp drop in energy consumption in Ireland in 2020, as the country spent much of the year in high-level Covid 19 restrictions.
The Sustainable Energy Authority of Ireland has published is 2020 National Energy Balance report.
It finds the energy related CO2 emissions, including international aviation, fell by 11.5%, or 4.3 million tonnes, last year.
The SEAI says this is "the most significant annual reduction since the height of the economic recession in 2009."
The primary driver of this reduction was lower consumption of oil products for transport, which is mainly attributable to the change in national and international travel patterns due to public health measures.
Dr. Denis Dineen is Energy Statistics Analyst at the SEAI.
He joined Clem Ryan on Monday's edition of Kildare Today.

The figures for 2020 show:
- Total energy consumption fell by 8.8% against a backdrop of a 5.4% contraction of the economy.
- Total transport energy use was down by over a quarter (26%).
- Oil-product use decreased by 16.5% - the largest annual reduction observed to date.
- The single largest reduction in oil-product use was the two-thirds drop in jet kerosene use for international aviation (64.3%).
- Consumption of road diesel and petrol were down 13.6% and 25.9%, respectively.
- Peat use fell by a third, mainly due to a halving of peat for electricity generation.
- The CO2 intensity of electricity improved by 8.1%, due to more renewable generation and less use of peat.
