Energy

Benefits Ireland

The main influence of a warming climate will be reflected in a decrease in energy requirements for commercial and domestic heating in Ireland. Model results (A1B and A2 emission scenarios) suggest major savings in winter and spring heating energy of 5–10% for the period 2021–2060 and 14–20% for 2061–2100 compared to the period 1961–2000. For summer and autumn, relative changes are even larger, although changes in absolute values are comparable (16).

Vulnerabilities Ireland

The existing energy infrastructure is at significant risk from climate change (13):

  • Many of the island’s power stations and oil refinery and storage facilities are located on the coast, and therefore vulnerable to rising sea levels, storm surges and higher waves.
  • Critical infrastructure across the island, including power stations, sub-stations, gas installations and oil terminals, and below-ground facilities such as cable tunnels and basements, are at increasing risk of flooding.
  • Extreme floods will affect dam safety and operating procedures for hydro power stations.
  • Higher winter flows and summer shortages could reduce the availability of hydropower and render it less efficient.
  • Strong winter wind speeds could benefit wind power generation, but summer reductions would have the opposite effect. Turbines could also be turned off more frequently to prevent damage during extreme weather, again reducing availability.
  • Extreme winds could damage overhead power lines.
  • Demand for electricity could rise dramatically during heatwaves to power air conditioning systems, and during droughts to pump water for water supplies, waste water systems and irrigation for agriculture.
  • The ‘water–energy nexus’ – the interdependence between energy for water and waste water, and water for energy – will become increasingly complex.

Opportunities Ireland

Wind power

Wind share of total electricity consumption in Ireland was 10.1% by the end of 2010. Overall in the EU, in a normal wind year, installed wind capacity at the end of 2010 meets 5.3% of the EU’s electricity needs (11).

Ocean energy

Ireland aims to become a world leader in the harnessing of ocean energy (10).

Vulnerabilities Europe

Supply

The current key renewable energy sources in Europe are hydropower (19.8% of electricity generated) and wind. By the 2070s, hydropower potential for the whole of Europe is expected to decline by 6%, translated into a 20 to 50% decrease around the Mediterranean, a 15 to 30% increase in northern and eastern Europe and a stable hydropower pattern for western and central Europe (1,3,4). In areas with increased precipitation and runoff, dam safety may become a problem due to more frequent and intensive flooding events (5).

Climate change impacts on electricity markets in Western Europe

The expected climate changes in the 21st century are likely to have a small impact on electricity prices and production for the energy markets of Western Europe. This has been estimated by modelling three climatic effects (14):

  • changes in demand for electricity due to changes in the need for heating and cooling,
  • changes in supply of hydropower due to changes in precipitation and temperature, and
  • changes in thermal power supply due to warmer cooling water and therefore lower plant efficiency.

According to the model results each of these three partial effects changes the average electricity producer price by less than 2%, while the net effect is an increase in the average producer price of only 1%. Similarly, the partial effects on total electricity production are small, and the net effect is a decrease of 4%.

The greatest effects of climate change are found for those Nordic countries with a large market share for reservoir hydro. In these countries total annual production increases by 8%, reflecting an expected increase in inflow of water. A substantial part of the increase in Nordic production is exported; climate change doubles net exports of electricity from the Nordic countries, while the optimal reservoir capacity is radically reduced (14).

Adaptation strategies Ireland

Stop using peat for energy

In Ireland, peat has been used for centuries to warm homes and fire whiskey distilleries. Peat power peaked in the 1960s, providing 40% of Ireland’s electricity. But peat is particularly polluting. Burning it for electricity emits more carbon dioxide than coal, and nearly twice as much as natural gas. In 2016, peat generated nearly 8% of Ireland’s electricity, but was responsible for 20% of that sector’s carbon emissions. In order to lower its carbon emissions, Ireland intends tocut its peat supply for electricity by a third by 2020 and end it completely by 2027 (17).
