Overview • Context • Irish energy trends • Irish energy options • Irish energy scenarios • Conclusions
Context “The trouble is that no realistic technological, economic and political strategies for the warding off of the impacts of a decline in conventional oil supply are in sight.” Society of Danish Engineers and the Danish Board of Technology (2004)

Context summary • We are not meeting our climate change commitments • Fossil fuel prices are volatile and rising for the forseeable future, threatening the economy • While demand for oil continues to increase unabated, a peak in oil production is imminent

Overview • Context • Irish energy trends • Irish energy options • Irish energy scenarios • Conclusions
Irish energy options – coal? • Large coal reserves worldwide, but ultimately not sustainable • Coal is greenhouse gas intensive • Large-scale sequestering of CO2 is still in the concept stage • Coal cannot easily replace transport fuels • Conclude: coal can only aid the transition toward energy sustainability, along with oil and gas
Irish energy options – nuclear? • Concerns about waste disposal, cost, security, construction time • In Ireland nuclear electricity generation appears to be socially unacceptable • The European Nuclear Society (euronuclear.org) states that “all 439 world-wide operated nuclear power plants can be supplied for several decades” with world uranium reserves, i.e. nuclear develop-ment is fuel supply limited just like fossil fuels • Conclude: nuclear fission will not aid the transition toward energy sustainability in Ireland
Irish energy options – renewables? • Cost concern • Grid integration concern – supply variability and availability (actually a cost concern) • Huge indigenous renewable energy resource (see next slide) • Virtually no greenhouse gas emissions • Will not be affected by fossil fuel price volatility • Conclude: renewable energy presents the only known possibility for energy sustainability in Ireland

Overview • Context • Irish energy trends • Irish energy options • Irish energy scenarios • Conclusions
Irish energy scenarios • Fossil fuel prices are volatile and increasing • We are one of the world’s highest contributors to global warming on a per capita basis • Ireland presently imports 90% of its energy • Ireland has a massive indigenous RE resource, that is available at reasonable cost • There is presently no other commercial technology that can ultimately replace fossil fuels • Conclude: It is a prudent and conservative policy for Ireland to embark on a substantial renewable energy development programme.
Irish energy scenarios • We will use everything available, but “wind, wave and wood” will be our primary energy sources • For electricity: wind and wave • For heat: bioenergy (wood) and heat pumps • For transport: electric vehicles, with some biofuels
Irish energy scenarios • Can the economy sustain the capital investment required? • What is the time frame over which we must make this transition? • This is has been investigated using the ECCO model of the Irish economy (www.energyscenariosireland.com)
Irish energy scenarios • ECCO Model results: • Business-as-usual will not work, whether the oil peak is now or in 2030 • If we launch a substantial national programme for energy sustainability, the economy can cope with the capital investment required, but only if the oil peak is later rather than sooner • Our options appear limited
Irish energy scenarios “If the time horizon for the impending peak in the production of cheap conventional oil is as short as one or two decades or less, the problems involved in handling the situation are of a specific, practical nature. Therefore, economic policies should not rely on general, theoretical assumptions that technological progress will ensure sufficient supplies of oil or substitutes for oil.” Society of Danish Engineers and the Danish Board of Technology (2004)
Overview • Context • Irish energy trends • Irish energy options • Irish energy scenarios • Conclusions
Conclusions • We need urgent actions, such as: • Large-scale energy conservation • Large-scale development of onshore and offshore wind energy • Large-scale development of bioenergy • Large-scale development of wave energy • Interconnection with Britain and Europe
Conclusions • More urgent actions: • Inclusion of aeroderivative gas turbines in the generation mix • Large-scale development electricity storage facilities • Development of the grid to allow substantial generation in the west of the country • Large-scale demand-side management
Conclusions • The fossil fuel era can only be regarded as a useful but very brief period in human history • Irish energy policy has not yet accounted for the crucial factor of the approaching oil peak
Conclusions • The price of energy is set to rise for the foreseeable future as fossil fuels decline • This threat creates an opportunity for renewable energy, which offers the only known possibility for energy sustainability • A renewable energy future is desirable, possible and inevitable
