China plans to upgrade its energy structure to cut carbon emissions and reduce costs in transmission of power, Shanghai Daily learned yesterday at the green technology seminar of the China International Industry Fair.
China National Offshore Oil Corp is developing a rig that is able to work in over 3,000-meter-deep water as deep-sea oil is expected to account for 60 percent of energies China will get from the ocean crude in the coming five years, said Zeng Hengyi, vice chief engineer of the company.
Being able to do so would slash China's energy costs by lessening the nation's reliance on import of crude, which in September grew 18 percent year on year, making China the largest crude importer globally.
CNOOC is also trying to use nuclear power to exploit oil sources, which would lower carbon emissions in the procedure, Zeng said.
China also plans to develop a more scattered power station layout, which officials call a "distributed generation system," to enhance power transmission efficiency while helping more areas get access to electricity, said Yu Yixin, an academician at the Chinese Academy of Engineering.
China has long suffered energy waste as it transmits electricity from the west, which has abundant coal, to the eastern parts of the country.
"Although east China lacks coal, it has more wind and sunshine," Yu said. "It enables the nation to build power stations using diversified resources in more areas."
Without the energy waste in the long-distance transmission, the "electricity utilization rate would be tripled from the conventional way," Yu said. "More areas can use the power generated locally and enjoy cheaper costs and cleaner energy."
By 2020, it is envisaged that Chinese would pay 0.80 yuan (12 U.S. cents) for per kilowatt-hour electricity, below the 1 yuan per kWh on average presently. By 2030, the price would be below 0.60 yuan per kWh.
