SEAI Geothermal Atlas modelled subsurface temperatures at 5,000m depth in degrees Celcius. The borehole temperature map at 5,000m depth has been modelled with temperatures calculated only from geothermal gradients in boreholes that reached 500m. The unavailability of data at depths below 2,500m means the data used in this map are of necessity only an indication of the possible temperatures that may be encountered at this depth.

SEAI Geothermal Atlas modelled subsurface temperatures at 500m depth in degrees Celcius. The borehole temperature map at 500m depth has been modelled from measured and calculated temperatures in 75 boreholes in counties throughout the Republic of Ireland and Northern Ireland. The modelled data have been produced from boreholes that reached 500m, together with temperatures calculated from geothermal gradients in boreholes that reached 300m.

SEAI Geothermal Atlas modelled subsurface temperatures at 10m depth in degrees Celcius.

This annual publication from the Sustainable Energy Authority of Ireland (SEAI) presents national energy statistics on energy production and consumption in Ireland over the period 1990 – 2014. Specifically, the report presents energy trends and underlying drivers as well as discussing sectoral energy consumption and how energy trends relate to Government and EU renewable energy targets. Timely and reliable energy statistics underpin evidence-based decision making. To this end, this publication presents a comprehensive overview of energy supply and demand in Ireland in order to inform Government policy and the wider energy debate. The information in the report is based on an energy balance for the country which shows the flow of energy from production, transformation and energy sector own use through to final consumption in different sectors of the economy. The energy balance is the starting point for the construction of various indicators of energy consumption (for example consumption per unit of GDP), of energy efficiency and also of other areas of national interest such as energy-related greenhouse gas (GHG) emissions. The data in the energy balance is based on monthly and annual surveys received from approximately 300 organisations including energy producers, import/export companies and energy supply companies. In addition, SEAI uses this data to fulfil Ireland’s energy statistics reporting obligations to Eurostat, under the EU Energy Statistics Regulation (1099/2008 EC), and to the International Energy Agency (IEA) through the completion of upwards of one hundred annual, quarterly, monthly and ad hoc questionnaires each year. The energy balance develops continuously as new methods and methodologies become available. This ensures that the best information is available. The main changes related to the period 1990 – 2014 are presented in this report and are described later. A companion publication, Energy Statistics – 2015 Report, is also available, presenting the background data for the analysis contained herein. Additionally, Energy in Ireland Key Statistics is available, which summaries Ireland’s energy statistics in a concise pocket-sized booklet. It is intended that these publications serve as resources for policymakers, analysts and researchers with an interest in energy use in Ireland.

SEAI Geothermal Atlas modelled subsurface temperatures at 100m depth in degrees Celcius. The borehole temperature map at 100m depth has been modelled from measured temperatures in 94 boreholes in 22 counties throughout the Republic of Ireland and Northern Ireland.

SEAI Geothermal Atlas modelled subsurface temperatures at 1,000m depth in degrees Celcius. The borehole temperature map at 1,000m depth has been modelled from measured and calculated temperatures in 72 boreholes in counties throughout the Republic of Ireland and Northern Ireland. The modelled data have been produced from boreholes that reached 1,000m together with temperatures calculated from geothermal gradients in boreholes that reached 300m.

The Marine Energy Supply Chain Database provides a list of companies and services for the marine renewable energy sector in Ireland. The companies listed in the database provide services to the wind, wave and tidal energy sectors covering areas from initial development and design through to deployment and operation.

SEAI Geothermal Atlas modelled subsurface temperatures at 2,500m depth in degrees Celcius. The borehole temperature map at 2,500m depth has been modelled from 2 measured and 47 calculated temperatures in 49 boreholes in counties throughout the Republic of Ireland and Northern Ireland. The modelled data have been produced from the 2 boreholes that reached 2,500m, together with temperatures calculated from geothermal gradients in boreholes that reached 500m. As most of the temperatures used in this modelling are calculated, more caution must be used in the interpretation.
