That's what Germany did, but such intermittent renewables can't power an industry-heavy country by themselves for obvious reasons (e.g. the sun tends to set at night)
No matter how much renewables capacity you want to install, you always need a controllable and reliable source for the baseload : that will be either coal, gas, hydro or nuclear. Only two of those are low carbon btw.
So let's see :
- Germany doesn't have the geography for hydro (unlike say, Norway).
- They don't want nuclear because politics.
- They became partly reliant on Russian gas, an extraordinary geopolitical own goal (and hilariously, sold by a Greenpeace-affiliated energy company as "green gas")
- The only other solution left is coal, lots of coal. That's what Germany has been doing despite political promises to phase it out.
The two main end results of this policy are :
- Germany has some of the worst CO2 emissions per kWh produced of large European countries. As I write this, it's emitting 23 times more than France (the poster child for nuclear) per kWh. Source : https://app.electricitymaps.com/map
- An estimated 22.900 premature deaths every year across the EU from coal-fired power plants. Germany's plants cause an estimated 2490 premature deaths per year in neighbouring countries alone. Source : https://caneurope.org/report-europe-s-dark-cloud-coal-burnin...
Imagine if France had a nuclear incident causing 2490 deaths in neighbouring countries, every year ?
Nuclear is like air travel : spectacular when it fails, but much safer than all other modes of transportation.
