There would probably be many practical and financial reasons why we can't - (in this sort of time frame anyway).

For a start the Swedes were well ahead of the game. I'm by no means an expert on the subject but they have been investing hugely in researching and implementing renewables since the 1980's (at least ). In 2003, 40% of their energy was from renewables. We have some catching up just to get to that point.

The most important question is how we would finance it. The Swedes willingly pay higher taxes to fund this kind of thing. Are Irish people prepared to do the same?
