Renewable energy could make fossil fuels cheaper 
The International Energy tells us that sufficient progress in moving
to renewable energy could make fossil fuels cheaper.
That is true, but the IEA does not seen to realize that that would be
a deadly trap for society.  The lower price would threaten to entice
people to move back to, or continue using, fossil fuels and continue
driving the world into climate mayhem.
The disadvantage of fossil fuels is not expense or scarcity.  It is the
harm they do by producing CO2.  A suitable carbon tax could make sure
these fuels continue becoming more expensive, so that humanity would continue to reduce its use of them.
