As Taiwan grows more enthusiastic over the development of renewable energy, a researcher is suggesting that the government put the brakes on traveling in that direction before more energy is wasted.
"Many studies have found that the energy devoted to produce renewable energy and biofuel has exceeded output energy," Daigee Shaw (蕭代基), president of the Chung-Hua Institution for Economic Research (CIER, 中經院), said at a press conference yesterday.
More energy is required to produce a solar cell than the cell can generate in its lifetime, Shaw said.
Attacking enthusiasm for cure-all renewable energy, Shaw said pollution and greenhouse gas emissions are still being generated during production of green energy.
Limited and unstable supplies of renewable energy, such as through wind power, solar power and hydraulic power, can hardly meet growing demand, Shaw said.
As a result, the government should review its energy policy and develop renewable energies that can yield net energy, he said.
The institution has submitted suggestions to the government for re-examining renewable energy policy. But the Cabinet insisted on a policy of pushing the installed capacity of renewable energy to 10 percent by 2010, Shaw said.
Taiwan imports more than 98 percent of its energy, and feels the pinch whenever energy prices rise.
The nation may suffer power shortages within five years unless additional generators are built, the Ministry of Economic Affairs said in June last year.
The government will favor plans for coal-fired stations when it awards contracts to build new capacity next year because they are cheaper to run and easier to supply than those fueled by gas.
"It looks like we'll have to rely on coal," Chan Wen-hong, an executive officer at the Bureau of Energy, said on Thursday.

The new projects aim to supply an extra 1,980 megawatts of capacity, enough to meet 5 percent of the nation's peak summer electricity demand. Tenders close on Dec. 5, and the government is likely to name two or three contract winners before the end of this February, Chan said.
"The choice of coal is pragmatic," Jeffrey Bor (
Gas-fired power plants are less favored because of shortages in supply and the time needed to build pipelines, he said.
A proposed 100 percent tariff on chip imports announced by US President Donald Trump could shift more of Taiwan’s semiconductor production overseas, a Taiwan Institute of Economic Research (TIER) researcher said yesterday. Trump’s tariff policy will accelerate the global semiconductor industry’s pace to establish roots in the US, leading to higher supply chain costs and ultimately raising prices of consumer electronics and creating uncertainty for future market demand, Arisa Liu (劉佩真) at the institute’s Taiwan Industry Economics Database said in a telephone interview. Trump’s move signals his intention to "restore the glory of the US semiconductor industry," Liu noted, saying that
On Ireland’s blustery western seaboard, researchers are gleefully flying giant kites — not for fun, but in the hope of generating renewable electricity and sparking a “revolution” in wind energy. “We use a kite to capture the wind and a generator at the bottom of it that captures the power,” said Padraic Doherty of Kitepower, the Dutch firm behind the venture. At its test site in operation since September 2023 near the small town of Bangor Erris, the team transports the vast 60-square-meter kite from a hangar across the lunar-like bogland to a generator. The kite is then attached by a
Foxconn Technology Co (鴻準精密), a metal casing supplier owned by Hon Hai Precision Industry Co (鴻海精密), yesterday announced plans to invest US$1 billion in the US over the next decade as part of its business transformation strategy. The Apple Inc supplier said in a statement that its board approved the investment on Thursday, as part of a transformation strategy focused on precision mold development, smart manufacturing, robotics and advanced automation. The strategy would have a strong emphasis on artificial intelligence (AI), the company added. The company said it aims to build a flexible, intelligent production ecosystem to boost competitiveness and sustainability. Foxconn
Leading Taiwanese bicycle brands Giant Manufacturing Co (巨大機械) and Merida Industry Co (美利達工業) on Sunday said that they have adopted measures to mitigate the impact of the tariff policies of US President Donald Trump’s administration. The US announced at the beginning of this month that it would impose a 20 percent tariff on imported goods made in Taiwan, effective on Thursday last week. The tariff would be added to other pre-existing most-favored-nation duties and industry-specific trade remedy levy, which would bring the overall tariff on Taiwan-made bicycles to between 25.5 percent and 31 percent. However, Giant did not seem too perturbed by the
