Energy Scenarios Ireland 2.0: Enlightened Transition

THIS IS A DRAFT - SOME STATISTICS MISSING!

Motto: "I can see clearly now' (the rain has gone!)

The economy bounces back, driven by investment in low energy infrastructure changes, renewables and development and sales of technology to make energy efficiency painless. 50% of the resources of the country are used for the transition to an ultra-low carbon economy, a future similar to that of the UK's rebuilding program after the 2nd World War. (?what proportion were used by the building boom??). The key energy assumption is that overall energy use remains level with rapid gains in efficiency meeting increasing demand. There is a rapid move from oil and gas to electricity and a rapid increasing in renewables both for supply to the grid and for own use. Additional interconnectors allow us to buy and supply to the EU electricity market.

This is an optimistic scenario that explores the idea that the loss of the construction sector could be replaced with long and short-term investment in a move to sustainable energy. This includes not just renewable generation, energy storage and energy efficiency technology but also the mechanisms to encourage a swift switch from fossil fuels to renewables.

To enter this scenario, we believe a short sharp shock is required in order for us to understand our vulnerability and the urgent necessity of securing our energy supply. In this scenario an explosion of the gas pipeline in Poland just before Christmas 2008 is the trigger. This gives focus to those trying to resolve the economic crisis - rather than trying to fix the problem, they put in place structures that will enable a more desirable future.

In this scenario, we recognise that the future for energy in Ireland is electricity. A significant proportion of transport and home heating will come from electricity so while overall energy use declines in the short term as we use it more effectively, the requirement for electricity grows. We focus our attention on our strengths which is wind primarily and potentially wave and tidal. Biofuel production is increased but is a niche market for agriculture and commercial road transport. By building high capacity interconnectors to Europe (and potentially North Africa) we sell wind at times of plenty and purchase electricity from Europe to boost supply at other times.

The government has set a figure of 30% of our electricity from wind by 2020. In 2006 our capacity was 5.5GW and we used 24 billion kilowatts in 2006. As wind is intermittent, to reach 33% of our electricity from renewables, mostly from wind, we will require three times that in capacity or roughly 6GW of wind. If each windmill is 1GW (although larger ones are being built) and we have almost 1GW already installed, that will be 5000 windmills or 417 per year or 8 per week, every week, until then. In this scenario we go all out for wind building both onshore and offshore wind and the first policy to facilitate this is to create a real-time pricing market to encourage use of electricity when it is cheap (windy) and shift loads when it is expensive. In order to encourage support for installations by local people, all planning includes a sinking fund for the decommissioning of the turbines at end of life.

While Ireland cannot act unilaterally, we can seek to be a leader in creating a secure economy with stable energy prices and a plentiful supply of electricity.

Key Characteristics

Energy is expensive but stable is supply and price.
Labour is expensive
Credit is cheap
Raw materials are increasingly expensive
Transport is more expensive
Globalisation of some goods/services no longer beneficial.
Success measures are long term
The future is an electron economy

Risks

Worldwide recession stops projects.
Continued shortage of credit prevents rapid investment.
Persistence of Business as Usual view of the future makes change slow and difficult to implement
High capacity interconnector to EU important for this scenario so timing of supergrid is critical.
Changes are not rolled out in a coordinated way. eg. if public transport is not an option people must continue to use the car. Until real-time pricing comes into effect, wind cannot be increased.
