Germany's multiplied the share of its power coming from renewables several times over since the Chernobyl disaster pushed the issue to the forefront.
It's certainly possible to do in Germany. Many like to claim that this is not so in Ireland.
Any evidence for that?
This is vastly important economically, as a renewable resource has zero fuel cost going forward. Ireland currently has very weak national hydrocarbon resources, and our continued ability to reliably purchase them externally is extremely dubious.
So moving towards a zero-fuel-cost energy mix is priority number one.
That said, I'm open to honest views as to why Germany's success is impossible to replicate here. Especially since we have the power to learn from Germany's errors, like its unwise focus on PV solar in a cloudy country. I don't think it's necessarily beyond our power to avoid such obvious mistakes. Less obvious errors are inevitable, of course. But clearly the worst error is the notion of sticking to the status quo of hoping really hard that there isn't another financial crisis which makes oil imports less affordable.
