Renewable Energy Generating Efficiency

02/18/21

Total accumulated power generation of wind power and solar photovoltaics in 2020 is 8,066,489,848 kWh. According to the latest release of the Energy Bureau's 2019 annual carbon emission coefficient is 0.509 kg CO2 /degree, it can reduce 4,105,843 metric tons of CO2 emissions, which is about 414,732 hectares of afforestation benefits. Because it does not require fuel for power generation, it is equivalent to 2,016,622 kiloliter of fuel oil or 2,984,601 metric tons of coal-fired or 1,330,971 metric tons of gas-fired units.

Note:
  1. Shall be updated when the Bureau of Energy has published power emission factor of the year. According to power emission factor of 2020,JUN published by the Bureau of Energy: CO2 emission of around 0.509 kg per kWh.
  2. For wind power and solar photovoltaics power generation, every kWh can reduce 0.25 kg of fuel burnt, 0.37 kg of coal burnt, or 0.165 kg of gas burnt.
  3. Forestation benefits are based on the commissioned research of Forestry Bureau, Council of Agriculture. In 2010, it is estimated that fixed annual CO2 emission per HA of forest is 9.9 mt.
  4. Average household monthly energy consumption in 2020 is around 300 kWh, the power generated can supply the use of approximately 2,240,000 families for a year.
