The calorific value of 1 kilogram of ordinary coal supplied in the market is 5.8 to 6.4 kilowatt hours, and the calorific value of 1 kilogram of standard coal is 8.14 kilowatt hours. For unified comparison or statistical convenience, it is often converted into standard coal according to its calorific value. The conversion factor is: 1 kilogram of ordinary coal = 0.174 to 0.786 kilograms of standard coal, or 1 kilogram of standard coal = 1.27 to 1.40 kilograms of ordinary coal. In English, "standard coal" is called "coal equivalent" (coalequivalent). The main difference between conventional energy and new energy is that conventional energy refers to non-renewable and highly polluting energy such as coal and oil, while new energy refers to renewable, less polluting and easily accessible energy such as solar energy, wind energy, geothermal energy and biomass energy. The energy consumption elasticity coefficient refers to the ratio of energy consumption growth rate to the annual growth rate of gross national product. it can reflect a * * Or the level of regional economic and social development and energy development and utilization. 1 barrel of oil equivalent is equivalent to 6,000 cubic feet of natural gas.
