China is being the top country by thermal electricity net generation in the world. As of 2014, thermal electricity net generation in China was 3,985 billion kilowatthours that accounts for 26.74 % of the world's thermal electricity net generation. The top 5 countries (others are the United States of America, India, Japan, and Russian Federation) account for 61.85 % of it. The world's total thermal electricity net generation was estimated at 14,902.45 billion kilowatthours in 2014.
The amount of gross generation less the electrical energy consumed at the generating station(s) for station service or auxiliaries. Electricity required for pumping at pumped-storage plants is regarded as electricity for station service and is deducted from gross generation. In the conventional thermal power stations (or conventional thermoelectric) electricity is produced from the use of fossil fuels such as coal, fuel-oil or natural gas, by means of a thermodynamic cycle of water-steam. The word “conventional” is used to differentiate them from other thermal power stations, such as the nuclear or the combined cycle stations.
