>>3724983The US leads renewable energy research by a large margin (out of the total 250 billion USD invested in 2016 for renable energy, the US contributed half of that, more than anyone country), and like I said it doesn't use it the most.
Germany has 32.70% of its total energy as renewable
Sweden has 60.21% from renewable resources
China 24.32%
UK 22.33% renewable
US 14.27% in 2017
As for pollution
China emitted 10,641,789 kt (kilotons) of carbon into the atmosphere in 2015
The US emitted 5,172,336 kt in 2015
The EU emitted 3,469,671 kt in 2015
India emitted 2,454,968 kt in 2015
The USA is the 7th highest emitter of carbon pollution on a per capita basis, and 2nd on a total emission basis. We also have the sunniest region in all of the Americas and use solar panels everywhere there, on top of also having more nuclear reactors than any other nation.
