Fun Fact: In the first half of the 20th Century, Ireland's electricity was mostly from renewable energy sources.
Well, to be pedantic, source singular.
The Ardnacrusha Hydroelectric Dam, completed in 1929, was the largest Hydroelectric Dam in the world at the time, and generated enough electricity to supply the entire country.
By 1935, thanks to rapid expansion of the Irish electrical grid to reach more of the population, it had dropped to 80% of Ireland's electrical output.
Nowadays, it supplies only 2% of the nation's electricity consumption. As not every river is the Shannon, there aren't a lot of other hydroelectric dams around the country, and the most viable route for renewable energy here going forward is wind.
