Is the Concept of Clean Coal Realistic ?

There are a number of differing viewpoints on this subject. Ultimately, I believe at some point the way electricity is provided for with the massive scale of burning coal is doomed. But I cannot see any iota of change with a switch either gradually or more rapidly in the coming two decades and probably beyond that. Coal is going to be burned for electricity generation on a broad basis well into the 2040s and beyond. The vast majority of electricity will continue to be generated from the burning of coal in spite of what is is doing to the atmosphere and environment for a long time still. Only if there is a radical sudden change in the environment, global climate, ecosystems, and at places close to sea level will there start to be an impetus away from coal. Even if the concept of clean coal burning becomes a reality in the coming decades, global warming will hasten coal's demise over a generation or two as alternative energy sources like solar and wind become more available and inexpensive. Hopefully nuclear electricity generation will not re-emerge.
