The Ministry of Economic Affairs aims to quadruple the nation’s share of electricity from renewable sources to 90 billion kilowatt-hours (kWh) by 2030, it said yesterday, as a growing number of local enterprises set goals to achieve carbon neutrality.
Renewable energy, primarily from solar and wind sources, soared more than 80 percent to 23.8 billion kWh last year from 12.7 billion kWh in 2016, Bureau of Energy data showed.
The ministry’s announcement came after Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) on Tuesday said that it would not be able to achieve carbon neutrality by 2030 because of a scarce supply of renewable energy in Taiwan. The world’s biggest contract chipmaker joined the global corporate renewable energy initiative RE100 in 2020, committing to use only electricity from renewable sources by 2050.

“The supply of 20 million kWh is insufficient,” company chairman Mark Liu (劉德音) told shareholders during its annual general meeting.
TSMC’s overseas fabs in China and the US have reached a balance between emitting carbon and absorbing carbon emissions, Liu said.
The company reached net zero emissions by using renewable energy sources, and purchasing carbon credits and renewable energy certifications to offset emissions, the company said in its annual report.

Liu urged the government to step up its renewable energy efforts and called on state-owned Taiwan Power Co (Taipower, 台電) to increase the supply of electricity from renewable sources.
Only 10 percent of the electricity available for local businesses is sourced from renewable energy, he said.
The chipmaker operates a 12-inch fab and an 8-inch fab in China and an 8-inch fab in the US through its subsidiary WaferTech LLC. In Taiwan, it operates four 12-inch wafer gigafabs, four 8-inch wafer fabs and one 6-inch wafer fab.
TSMC also said its power consumption would continue to rise as it builds more facilities in Taiwan.
More than 75 percent of its greenhouse gas emissions come from electricity consumption, it said.
The chipmaker purchased 900 million kWh of electricity from renewable sources last year, Liu said.
In April, the company signed on to a joint procurement renewable energy program in Taiwan and a long-term renewable purchase agreement with ARK Power (誠新電力) to provide TSMC and its suppliers with 1 billion kWh per year for 20 years. TSMC would use half of that supply.
The bureau yesterday dismissed the chipmaker’s criticisms, saying that the government has liberalized the nation’s green electricity market, and that every company has full access to renewable energy from private power providers, or independent power developers.
The bureau said it respects the free-market mechanism.
Taipower is obligated to purchase renewable energy from power developers through a feed-in-tariff mechanism, the bureau said in a statement yesterday.
It also allows for supplying electricity from renewable resources to private enterprises, as energy purchase agreements with suppliers are severable contracts.
Private power suppliers are allowed to end contracts with Taipower and to sell power to new buyers, the statement said.
About 120 companies sourced 2.55 billion kWh of renewable energy last year, it said.
The New Taiwan dollar is on the verge of overtaking the yuan as Asia’s best carry-trade target given its lower risk of interest-rate and currency volatility. A strategy of borrowing the New Taiwan dollar to invest in higher-yielding alternatives has generated the second-highest return over the past month among Asian currencies behind the yuan, based on the Sharpe ratio that measures risk-adjusted relative returns. The New Taiwan dollar may soon replace its Chinese peer as the region’s favored carry trade tool, analysts say, citing Beijing’s efforts to support the yuan that can create wild swings in borrowing costs. In contrast,
Nvidia Corp’s demand for advanced packaging from Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) remains strong though the kind of technology it needs is changing, Nvidia CEO Jensen Huang (黃仁勳) said yesterday, after he was asked whether the company was cutting orders. Nvidia’s most advanced artificial intelligence (AI) chip, Blackwell, consists of multiple chips glued together using a complex chip-on-wafer-on-substrate (CoWoS) advanced packaging technology offered by TSMC, Nvidia’s main contract chipmaker. “As we move into Blackwell, we will use largely CoWoS-L. Of course, we’re still manufacturing Hopper, and Hopper will use CowoS-S. We will also transition the CoWoS-S capacity to CoWos-L,” Huang said
VERTICAL INTEGRATION: The US fabless company’s acquisition of the data center manufacturer would not affect market competition, the Fair Trade Commission said The Fair Trade Commission has approved Advanced Micro Devices Inc’s (AMD) bid to fully acquire ZT International Group Inc for US$4.9 billion, saying it would not hamper market competition. As AMD is a fabless company that designs central processing units (CPUs) used in consumer electronics and servers, while ZT is a data center manufacturer, the vertical integration would not affect market competition, the commission said in a statement yesterday. ZT counts hyperscalers such as Microsoft Corp, Amazon.com Inc and Google among its major clients and plays a minor role in deciding the specifications of data centers, given the strong bargaining power of
Nvidia Corp CEO Jensen Huang (黃仁勳) is expected to miss the inauguration of US president-elect Donald Trump on Monday, bucking a trend among high-profile US technology leaders. Huang is visiting East Asia this week, as he typically does around the time of the Lunar New Year, a person familiar with the situation said. He has never previously attended a US presidential inauguration, said the person, who asked not to be identified, because the plans have not been announced. That makes Nvidia an exception among the most valuable technology companies, most of which are sending cofounders or CEOs to the event. That includes
