Alternative energy in the form of wind-power has long been touted for Ireland but frankly the building of these windmills strikes me as window dressing. The power output is low relative to the environmental noise and sight pollution involved in their construction.
I would disagree. Turbine technology is improving very quickly, with the most powerful turbine currently available rated 6MW, and more typical turbines 1-2MW. In addition these can reach 40% capacity in Ireland compared to 20% in mainland Europe. So if it is commercially viable to erect these things in Austria (at 20% capacity); it must be (it is) very lucrative to build them in Ireland. Combine with more pumped storage schemes Ireland could easily generate enough power for the whole country.
At the moment Ireland already has a total installed capacity of 600MW from wind energy. That is the same as Tarbert (the third largest power plant in Ireland). Airtricity alone (who only make up a 25% share of wind energy in ireland at the moment) has planning permission granted for an additional 200MW. Other companies have p.p for many more wind farms also.
Also we could utilise offshore far more - the Arklow bank only has seven 3.6MV turbines and already produces 25MV - imagine if they actually did build the 200 of them that was planned at first? That would be 720MW of power capacity - all off shore and largely out of sight. Our famous Moneypoint only produces 900MW and manages to power nearly 20% of the country. So in theory self sufficency could be achieved by:
- Actually finishing the Arklow Bank
- Building 4-5 more major offshore windfarms
- Completeing all existing planning-permission-granted windfarms; no more than that needed!
- Building 2 or 3 more pumped storage schemes
If you did that we would hit about 100% supply (after allowing for 40% max operating capacity; and the increase in demand over next few years). If implemented, our landscape would not alter much from today and visual pollution would be no worse than today really.
Now imagine if we built 10 offshore farms of 250 5MW turbines each? And doubled on-shore capacity? And used solar, hydro, and wave power also? Obviously one can only speculate and dream - but seriously the potential exists for us to export perhaps 3 times our own needs. Thats billions and billions of euros worth of green power, thousends of new jobs, important export earnings leading to a very favorable balance of trade, more tax receipts of course, energy security, and a huge amount of interenational respect, admiration and prestige.
One last thing... image thirty 300 6MW turbine farms offshore, quadruppling existing onshore turbine numbers and replaceing existing farms with far more efficent and powerful turbines... i'm far too enthusiastic and of course its all a dream, never likely to be a reality - but it really really really could be!
