China
coal power building boom sparks climate warning
BBC,

Building
work has restarted at hundreds of Chinese coal-fired power stations,
according to an analysis of satellite imagery.
The
research, carried out by green campaigners CoalSwarm, suggests that
259 gigawatts of new capacity are under development in China.
The
authors say this is the same capacity to produce electricity as the
entire US coal fleet.
The
study says government attempts to cancel many plants have failed.
According
to this study, there was a surge in new coal projects approved at
provincial level in China between 2014 and 2016. This happened
because of a decentralisation programme that shifted authority over
coal plant construction approvals to local authorities.
The
report says that at present China has 993 gigawatts of coal power
capacity, but the approved new plants would increase this by 25%.
China's
central government has tried to rein in this boom by issuing
suspension orders for more than 100 power plants but this analysis
suggests that these efforts have been significantly less effective
than previous news reports had indicated.
In
this study, the researchers used satellite photos to examine every
power plant that was subject to a suspension order. They found
construction ongoing at many locations.
For
instance, in September last year, China's National Energy
Administration ordered a group of plants - that together could
produce 57 gigwatts of electricity - to slow down construction. The
organisation also prohibited them from connecting to the grid in
2017.
However
the satellite data suggests that half of this capacity appears not to
have slowed down at all.
"This
new evidence that China's central government hasn't been able to stop
the runaway coal-fired power plant building is alarming - the planet
can't tolerate another US-sized block of plants to be built,"
said Ted Nace, from CoalSwarm.
"It's
not too late for the central government to fix the problem, but they
have to start cancelling projects, not just rescheduling them."
If
this extra capacity was operational, it would make it much more
difficult for the world to limit CO2.
According
to the International Energy Agency (IEA), for the world to limit
warming to below 1.75C above pre-industrial conditions, China would
have to close all its power plants that don't have carbon capture and
storage facilities within 30 years.
"Avoiding
dangerous climate change requires essentially phasing out coal plants
globally by 2045," said Christine Shearer, lead author of the
report. "China needs to begin planning for the aggressive
retirement of its existing coal fleet, not building hundreds of new
coal plants."
However,
some researchers believe that the building of these plants has more
to do with boosting the local economy in China than with boosting
emissions.
"Coal
power plants run only about half the time in China, and one could
argue the new capacity is not needed," said Glen Peters, from
the Centre for International Climate Research in Oslo, who was not
involved with the report.
"The
new coal power plant builds are most probably about keeping the
economy ticking along, particularly from a provincial government
perspective, rather than being needed for future electricity
generation."
This was ALWAYS the real situation aside from the hype and propaganda
