That was my point No7, there are issues. BlackAndAmberGambler puts up a post, admittedly a bit flippant but relevant nonetheless. Whether true or not, it has been suggested that the reason for Spain's blackout was relying totally on renewable energy. Something they were apparently bragging about only a week before.
His post was met with dismissive responses and Shoot Spiderman's reply suggesting because renewables are used in the countries he listed, BAAG's comment was without any merit. So I checked them out because posting a list of countries that are using 100% renewable energy is only half the story.
I'm not against renewables, far from it, but the attitude on here towards opposing views rears it's head again. No acceptance that, at this stage, totally relying on renewables is a risky strategy.
