You don't deserve to be downvoted for your statement, as it is correct- coal plants can function 34/7, unlike most other green sources other than geothermal.

Of course, gas plants can also function continuously, and for baseline, nothing beats nuclear. But burning gas for energy is far better than just releasing it unburned in to the air, or flaring it for no productive purpose.

As we get more large-scale batteries online, the variable output of things like wind and solar will matter less, and they will be able to provide an ever-increasing percentage of our energy mix. This is well underway, but it is a huge task that will take a long time to complete.
