Some time ago, many places cut electricity, after a series of measures, recently the coal reserves of the national power plant exceeded 100 million tons, 100 million tons is enough for us to use for a few days.
With the current coal consumption of one ton of coal, it can generate about 3,000 degrees of electricity.
One kWh of electricity = 1KW•h = 3600KJ.
One kilogram standard coal calorific value = 29.3 MJ
So theoretically, 1 kilogram of coal can generate about 8.14 degrees of electricity.
But in fact, the utilization rate is not so high, only about thirty percent, 1 kilogram of coal can generate about 3 degrees more, according to 3 degrees, a ton of coal can generate 3000 degrees.
A family's electricity consumption is calculated as 20 degrees a day, and one ton of coal can supply 150 families for a day.
The country needs 2.7 million tons of electricity a day on a scale of 400 million households.
Therefore, 100 million tons is enough for all households in the country for 148 days and more than 3 months.
In fact, the residential electricity consumption is only a small part, accounting for about one-tenth of all electricity consumption, so the above number needs to be divided by 10, that is, 148 / 10 = 14.8 days, more than half a month.
It can be seen from this that the coal stock of power plants is still relatively abundant, in addition to wind power, photovoltaics, nuclear power and so on.
