We can easily get rid of coal, that's just stable baseline load.

The tricky part is that gas is currently needed to regulate the variability of renewables, to match to demand. We will need some big advancements and adoption in battery storage to replace gas entirely.

There is a thing called the "duck curve" where Solar drops off shortly before peak usage hours, this leads to massive ramp rates needed as demand increases and solar supply drops off. Currently, we see a lot of Gas units turned on just for their ramp speed, and turned off after an hour, very inefficient.

The EU is also helped by being a larger energy collective, less inefficiencies from having seperate utilities like parts of the US.
