“Coal-fired power stations emit over 10 Gt of carbon dioxide each year,[4] about one fifth of world greenhouse gas emissions, so are the single largest cause of climate change”
The counter factual; if the 60% of electricity coming form wind or sunshine at this instant was from coal, then 10 Gt of carbon dioxide each year becomes 20/30/40/50 Gt of carbon dioxide each year and global emmisions are significantly more than what they are now.

Purely hypothetical, but it is where we were.
