depending upon capacity
Just about one-half, due to losses of Energy.
4 electricity is conducted daily.
That very much depends on the cost of the coal. Question has no answer
To convert coal into coke, the coal is burned in an oxygen-depleted environment. When this happens, the impurities of the coal are burnt up but the carbon remains. This is why coke is much lighter than coal.
I am pretty sure that LESS electricity is generated with biomass, meaning that its use is not as common as coal.
Over half but not all of it
It's renewable energy. That means, if we use as much sun as we can today to produce electricity, it still all comes back tomorrow just as strong. Not like coal or oil which can only be used once. When we've burnt the coal or oil, it's gone.
Trains don't use electricity it uses coal trams use however electricity.
One third of coal's energy reaches the consumer.
Some reason you don't like coal mining? I notice you are using a computer- which is powered by electricity. You might want to see how much of the electricity that is used comes from coal before you decide you want to prevent coal mining.
1 kg of 235U = 3 000 t coal
1 year has 8766 hours, therefore a 100 watt bulb uses up 0.1 x 8766 units of electricity, that is 876.6 units. If coal was burnt to produce the energy, about 250 kg of coal (550 pounds) would be needed.
