Embracing a non-nuclear future
By Winston Dang 陳重信
On March 24, Democratic Progressive Party (DPP) presidential primary candidate
Tsai Ing-wen (蔡英文) announced her support for an energy policy that would turn
Taiwan into a “nuclear-free homeland” by 2025.
For those politicians who think nuclear reactors are so safe that we can cuddle
them while we sleep, Tsai’s no-nukes policy is just as scary as any earthquake
or nuclear emergency. These politicians keep saying that construction on the
Fourth Nuclear Power Plant cannot be halted, because the cost of doing so would
be more than NT$270 billion (US$9.23 billion). They warn that the price of
electricity would go up and that the energy supply for Taiwan’s industrial
sector would be a third short of what is needed — but this figure is wrong.
According to data released by the Bureau of Energy (能源局) in December 2009,
nuclear plants only contribute 8.7 percent of Taiwan’s total power supply, not
much more than liquefied natural gas at 8.4 percent. If the proportion of
Taiwan’s total electricity generation derived from renewable sources could be
raised from the present 4 percent to 25 percent or more by 2025, there is no
reason why Tsai’s plan to phase out nuclear power by that date could not be
achieved. Her proposal is in tune with the New Apollo Project proposed by the US
Apollo Alliance, which aims to produce 25 percent of that country’s power from
renewable sources by 2025. It is quite possible that Taiwan could achieve the
same goal that US President Barack Obama endorsed two years ago — to generate
100 percent of electricity from renewable sources by 2050. If the US can do it,
so can Taiwan.
Energy policy is a matter of supply and demand. In February, 2008, I led a tour
group on a visit to Beckerich, a small agricultural town in western Luxembourg
that has just 2,000 residents. The town uses cow and horse manure blended with
sawdust to produce methane through anaerobic digestion, and it has improved
electricity -transmission efficiency to more than 95 percent. In addition, every
home has solar panels on the roof that provide power for lighting and heating —
even in winter. The town has achieved an impressive 87 percent self-sufficiency
in energy. The scheme solves the problem of manure disposal by turning it into a
cheap source of bioenergy. As a bonus, many tourists visit Beckerich to learn
about its environmentally friendly innovations.
In 1985, the Danish parliament passed a resolution that nuclear power plants
would not be built in the country. Danish Minister for Climate and Energy Connie
Hedegaard is a strong advocate of energy efficiency and sustainable energy. By
raising the price of gasoline and imposing a tax on carbon dioxide emissions,
Denmark has taken energy-saving policy to the household level.
While Denmark’s energy consumption has remained flat, its economy has grown at a
respectable rate (GDP grew by 38.2 percent from 1990 to last year) and it has
relatively low unemployment at a bit more than 4 percent.
In 2007, between 16 percent and 18 percent of Denmark’s energy came from solar
and wind power, and that proportion is rising. Notably, Denmark has solved the
problem of effluent produced by its 25 million pigs by using it to generate
electricity and produce organic fertilizer.
There is no reason why the same could not be done in Taiwan, with its 6 million
to 7 million pigs. People might think of effluent and dung from pigs, cows and
horses as being without value, but put in the right place and used in the right
way they become precious energy resources.
All four of Taiwan’s nuclear power stations are included in the list of the
world’s most dangerously located plants. In 2005, a World Bank survey on
worldwide natural disaster risk found that Taiwan may be the most -vulnerable
place on Earth to natural hazards, with 73 percent of its land and population
exposed to three or more hazards and 90 percent of its population living in
areas at high relative risk of death from two or more hazards.
In addition, the frequency of extreme weather events has increased over the past
few years and they are becoming increasingly severe. Typhoon Morakot in 2009 and
Typhoon Megi last year brought some of the strongest winds and heaviest rain
that Taiwan has experienced in many decades. Taiwan is a high-risk area and that
risk is likely to increase in future.
On March 11, Japan’s Fukushima Prefecture was struck by a three-in-one disaster
— a magnitude 9.0 earthquake, which generated a tsunami, which in turn caused
explosions at a nuclear power plant. If we add the volcanic eruptions, gales and
heavy rainfall that have happened since then, it has been a six-in-one disaster.
It’s a rare combination, but it has happened all the same and the government has
to find a way to respond.
Could climate change and global warming lead to death and destruction on a mass
scale in Taiwan?
The local economy is driven by exports; should Taiwan ever be hit by a multiple
calamity including a nuclear disaster, it would set our economy back 50 years.
In light of the ongoing nuclear disaster in Japan, mankind needs to rethink the
concepts that underpin risk analysis in nuclear security. When assessing risk,
we must take into account the worst-case scenario of a three-in-one or even a
six-in-one disaster, where several kinds of disaster strike the same area at the
same time, and we have to reassess risks accordingly. Following the events in
Fukushima, no one in the world dares call himself an expert on nuclear safety,
because the old methods of risk assessment and the old ways of considering
environmental factors all have to change. Given that nobody dares claim that
they know how to judge the risk of a six-in-one disaster including an earthquake
and a nuclear accident, who can be convinced by talk of strict nuclear safety
measures. Who believes now that man can always conquer nature?
US authorities have already incorporated climate change factors among national
security concerns, but what about Taiwan? At a time when countries around the
world are starting to take measures in response, the question is would Taiwan be
prepared in the event of a nuclear disaster?
Following the March 11 earthquake in Japan, opinion polls in Taiwan show strong
public support for the idea of a nuclear-free homeland. In fact, Article 23 of
the 2002 Basic Environment Act (環境基本法) stipulates that: “The government shall
establish plans to gradually achieve the goal of becoming a nuclear-free
country. The government shall also strengthen nuclear safety management and
control, protections against radiation and the management of radioactive
materials and monitoring of environmental radiation, to safeguard the public
from the dangers of radiation exposure.”
Following the disaster in Japan, Germany took the lead in closing down older
nuclear power stations and many other countries have called a halt to the
construction of new ones. Countries around the world are reconsidering their
nuclear power policies and questioning whether they really need nuclear power in
view of the risks. Non-nuclear policy proposals that have been set aside for
years are being discussed once more.
In Taiwan, Tsai’s proposal for a nuclear-free homeland by 2025 is just a quiet
reminder of a policy orientation that already exists in law. The question now is
whether President Ma Ying-jeou (馬英九) will proceed in accordance with the law or
ignore it?
