I will believe it when I see it. The only countries with both cheap and clean electricity are those that built out extensive nuclear or got lucky enough to have access to other forms of cheap base load like hydro / geothermal.
As an Australian I can say that for me personally the free energy periods have been amazing and are an example of the functional free markets making life better for the average person.
Here in Queensland the state owns the regional electricity company, Ergon. ∴ most of what they do that doesn't generate money (such as doing free electricity rather than charging for it) is taxpayer-funded.
