2% of GDP is the estimate to go 100% renewables for the entire energy sector (not just electricity) for developed countries. For instance for Germany the estimate is 500 to 3000 bn EUR in total.
And this would stop global carbon emissions? What about the shipping industry, the mining industries, the fuel required to do all the shipping and mining and farming, etc. etc.?
My understanding is that nothing short of a massive, forced reduction in resource consumption will do anything to seriously slow down carbon emissions and curb climate change, if indeed it can be curbed.
