Data for 2017 has not been compiled yet, let's look at data for 2016 and 2015
Electricity production data:
Hydroelectricity, the production of electricity in 2016 was 1,180.7 billion kWh. , and in 2015 1,111.7 billion kWh in 2016, or 19.71%;
Thermal energy, electricity production in 2016 was 4,288.6 billion kWh and 4,186.8 billion kWh in 2015, or 71.60%
Energy nuclear, electricity production in 2016 213.2 billion kWh in 2016 and 171.4 billion kWh in 2015; accounting for 3.56%
Wind power generation was 241.0 billion kWh in 2016 and 185.3 billion kWh in 2015; representing 4.02%;
Photovoltaic energy production increased from 66.2 billion kWh in 2016 to 38.5 billion kWh in 2015 (photovoltaics refers to the production of photovoltaic solar energy)
Photovoltaic energy production increased by enabout 72% year-on-year between 2016 and 2015, or about 1.11%;
Photovoltaic power generation increased by about 300% week-on-week in 2017 and 2016 , or about 3%. 2018-2020 will be the explosive period for the domestic use of photovoltaic energy production!
The impact of this proportion is as follows:
1 Wind energy is generally stronger in spring and autumn, so the amount of wind energy generated in. these two seasons will increase. Relatively high, in summer and winter, due to the weakening of wind power, wind power generation will correspondingly decrease in summer and sunny days, because the sunshine duration is long and the intensity of the solar radiation; is high. In winter and on cloudy days, photovoltaic energy production will decrease.
2. The volatility of wind and photovoltaic power generation is mainly affected par weather conditions, such as changes in wind speed, cloud cover, etc., which will lead to unstable power generation.
