As of 2016 35% of our production came from Natural Gas vs 30% from Coal. So if anything we're natural gas based now.

That being said, I think you're on the right path as only 35% came from renewables (15%) or nuclear (20%).

So the 1% is accurate if the power generation remains static but renewables and nuclear are growth sectors. A bunch of reactors are allegedly coming online in the next decade. Wind and Solar are also growing quickly.
