Madam, – The opinion of two of Ireland’s leading energy economists on the impact of wind energy on energy prices is, according to Dick Keane (December 22nd), delusional.
Unfortunately, his own assertions are just that.
Mr Keane has neglected to recognise in his analysis that when wind power is generated it displaces fossil fuel use. This is not just a direct saving but also reduces the economy’s exposure to fuel price increases.
Further, his claim that wind generation in Ireland is limited when we need it most and thus must be backed 100 per cent by conventional generation is just wrong. In fact winds are strongest during the winter in Ireland.
Additionally, it is windier here during the day than it is at night. This correlates nicely with electricity demand in Ireland. The outcome is that wind capacity can replace a substantial amount of fossil fuel generation plant.
The impact of wind generation on the future electricity price is uncertain.
What is certain is that if we can meet our wind energy targets we will slash our CO2 emissions. Moreover, with increasing renewable energy we make the case for electric vehicles stronger and stronger. – Yours, etc,
