mpweiherSeven countries now generate 100% of their electricity from renewable energy

Specifically Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia and the Democratic Republic of Congo.
Not to downplay the positive steps that are being taken towards using renewable energy worldwide, but one must point out that all those countries except one are almost exclusively using hydroelectric power, whose availability at such scale is a geographical lottery. As for Iceland, which also relies mostly on hydroelectric power but not in such great a proportion, it makes up for it thanks to easy and abundantly available geothermal power (which, though environmentally friendly, is arguably not technically renewable).
Well yes, hydro and geothermal are the easiest (and earliest perfected) renewable sources to provide consistent base load. It would be odd if the first countries to achieve fully renewable power weren’t making use of those technologies.
Other countries will have to be more reliant on interconnects, diverse renewable mixes and batteries. Luckily this is now almost always cheaper and more secure than fossil fuels and the trend lines point towards that continuing to be more and more true over time.
