Can coal be clean?

Clean coal, no it still gets my hands dirty. Not funny. The combustion of any carbon containing fuel produces among other things
CO2. While it may be too late I think we should try to reduce our
CO2 production from ancient storage in the ground as much as possible. No matter how we burn coal or use it to produce other
hydrocarbon fuels the result is the same, more CO2 into the
atmosphere. Sequestered CO2 while possible costs more than non
carbon energy sources. We overlook nuclear energy because of a few
accidents, not accidents but criminal action by the operators and
builders of the nuclear power plant. The nuclear power plants in the
U.S.A. are inefficient outmoded and often poorly built. The so
called waste is recyclable usable isotopes. The design only uses
about 5% of the energy in the uranium fuel. There are new designs
that can use 95% of that energy. To be useful solar, wind, wave,
tidal energy need a storage system to provide 24/7 energy supply.
Major dam systems could be used for this storage. the generating
equipment is already in place. Just add the pipe lines and pumping
equipment and then solar and it's byproducts, wind etc, would become
a real usable energy source.
