In the "National Plan for Energy Saving and Carbon Reduction" mentioned under "CO2 and energy targets," the goal for energy consumption from "low-carbon sources" is to increase the percentage from 40% to 55% in 2025.

Further In March 2022, the Taiwan government published "Taiwan's Pathway to Net-Zero Emissions in 2050," which provides the action pathway to achieve the policy goal of 2050 net-zero emissions. It is based on the four major transition strategies, "energy transition," "industrial transition," "lifestyle transition" and "social transition," as well as the two governance foundations of "technology R&D" and "climate legislation," and is supplemented by "12 key strategies." It aims to develop action plans for key areas of expected growth with regard to energy, industrial and life transition to implement net-zero transition goals. The policy goals are ambitious, including the following:

• By 2050, 100% of new buildings and more than 85% of existing buildings will be nearly zero-carbon buildings.
• By 2050, 60%-70% of total power generation should come from renewable energy.

The main investments, including industrial developments, are focused on wind and solar power generation facilities. The plan is to encourage commercial sectors to set up offshore wind turbines with a capacity of 3,000 megawatts before 2030, so that the sum capacity will reach 4,200 megawatts together with the onshore generators. As of the end of 2023, wind turbines with a total capacity of around 2,250 megawatts had been installed. As for solar energy, the plan is mainly to promote solar panels on the roofs of private buildings and factories so that solar energy may reach 20,000 megawatts in 2025. By the end of 2023, it had reached an installed capacity of around 12,220 megawatts.

Aside from wind and solar energy, other goals for renewable sources include hydroelectric power generation of 2,200 megawatts with a capacity of 3,350 megawatts, biomass power generation of 950 megawatts, and geothermal power generation of 200 megawatts in 2030.

Although there are national targets for renewable sources, there is no specific goal or quantified target set up for buildings.
