Growing demand, inefficiency blamed
for China's shortage of energy supply
by Jiang Guocheng
BEIJING, June 13 (Xinhuanet) -- Accelerating development of power-intensive machinery, auto, steel and manufacturing sectors, the growing pace of urbanization and low energy efficien cy are blamed for China's extensive shortage of
energy, which may worsen before 2020.
An industrial report
of the State Information Center with the National Bureau of Statistics forecasts
China will face a more severe power shortage this year than it did in 2003. A
total of 24 provincial areas imposed power brownouts in the past few
months.
In an exclusive interview with Xinhua earlier this
week, Xu Dingming, a leading official with the Energy Bureau of the State
Development and Reform Commission, said China's output of primary energy was
equal to 1.603 billion tons of standard coal last year, up 11 percent over the
previous year.
But demand outpaced supply as shortages of
coal, power and oil were reported in many areas of China, whose economy grew by
9.1 percent last year, and over 7 percent in the two years before
2003. Growing
demand
Last year saw many coal-fired power plants
in China sound the alarm bell of running out of coal, and 22 provincial areas
imposed brownouts due to power shortage. China produced 170 million tons of
crude oil and imported about 100 million tons of crude and refined
oil.
Xu said China is now in the middle stage of
industrialization phase characterized by faster development of energy-extensive
machinery, auto, iron and steel sectors.
Urban residential
consumption of energy also rose dramatically due to the country's fast pace of
urbanization and improved standard of living.
Statistics
from the Ministry of Construction show that from 1978 to 2002, the level of
urbanization in China increased from 17.92 percent to 39.1 percent. By the end
of 2002, there were 660 cities and 20,600 towns in China with a combined
population of 502 million.
A growing number of the urban
residents have more spacious houses, more electronic consumer goods and cars,
which push up the per-capita consumption of energy, said Xu.
The per-capita energy consumption for urban residents is 250 percent more than
that of their rural cousins, said Xu.
Meanwhile, overseas
investors are relocating their processing and manufacturing sectors, especially
the manufacturing sector characterized by high energy consumption, to China,
further overstraining the country's energy supply.
Excessive
investment in the country's iron and steel, electrolytic aluminum, and cement
sectors has been another contributing factor of the power shortage, said the
official.
Energy
inefficiency
Low energy efficiency remains a
problem for China as its comprehensive energy efficiency stands at 33
percent, 10 percentage points lower than that of developed countries, and
China's energy consumption for per-unit output value is twice as much as
that of developed countries, said Xu.
A survey conducted by
China's power sector shows its coal-fired power plants and power transmission
companies would save an equivalent of 120 million tons of standard coal if their
energy efficiency was raised to the advanced level of developed
countries.
Wang Guangtao, minister of construction, said
energy consumption of buildings in China is double or triple that of developed
countries of comparable climate.
Experts estimate that if
new buildings and existing buildings in China all conform to advanced energy
conservation standards by 2020, their energy consumption would drop by an
equivalent of 335 million tons of standard coal per year, compared with doing
nothing at all. That's about one fifth of China's annual energy
consumption.
The shortage signals
more problems than it appears, such as the country's worsening pollution due to
growing consumption of coal, and energy security, said Xu.
Worsening pollution from burning coal
Xu said China's energy sector has to face two
major challenges as growing energy supply will pose pressure on the environment
and low energy efficiency has become a major constraint on the expansion of the
energy sector and sustainable social and economic problems. Coal accounts for 80
percent of the country's energy consumption.
China
discharged 19.27 million tons of sulfur dioxide in 2002, 90 percent of which
came from burning coal, and 200 million tons of ash and solid
waste.
The country's environmental watchdog said the amount
of sulphur dioxide resulted in acid rain pollution in one third of the country,
causing billions of dollars in economic losses.
But China's
energy demand in 2020 is projected at 3 billion tons of standard coal, almost
double that of its output for 2003, which means pollution arising from
coal-burning would worsen accordingly, putting further pressure on the country's
water resources and transporting system.
Based on
China's current coal production plans and decrease of producing capacity of
existing coal mines, officials said the country's coal supply would be at least
100 million tons short of demand by 2010, and the shortage would jump to 600
million tons by 2020.
Efforts to increase supply,
save energy
In order to ease the current energy shortage, the Chinese
government decided earlier this month on a package of measures to deal with the
issue, such as curbing blind investment and wasteful duplications in some
industries and cutting irrational demand, improving coal supply for areas
suffering from power shortage, accelerating construction of energy and transport
projects to expand supply and improving efficiency of energy
consumption.
Officials and experts said China's power
shortage would ease in 2005 and disappear in 2006 due to increased energy
supply, but the balance between the supply and demand would not last long if
China failed to boost supplies.
More than 200 billion yuan
(about 24.1 billion US dollars) of capital went to the construction of power
generating projects in 2003, almost equaling the amounts of 2001 and 2002
combined.
Zhou Heliang, executive vice president of the
China Electrotechnical Society (CES), said that China's installed power
generating capacity would experience big growth from now to
2020.
He said China had 380 million kilowatts of installed
power generating capacity by the end of 2003. The level might exceed 450 million
kilowatts by 2005, 650 million kilowatts by 2010 and around 950 million
kilowatts by 2020.
A week-long nationwide campaign to
educate the public about methods to save energy, sponsored by a number of
government agencies, started on June 6. Among these methods, citizens are
advised to unplug their electrical appliances if they would lay idle for a long
period, avoiding power consumption from the standby mode.
Deliberations on energy efficiency in buildings have surfaced and some cities
have taken steps in this direction.
Shanghai has taken the
lead in the reform. Design and construction of new residential buildings and
public buildings in the country's biggest industrial city must comply with
energy conservation standards as of 2006. Enditem |
