the coal is burnt to boil water which is used to spin a giant coil of wire through a pully and wallah you have eletricity
Electricity is generated in power plants; those power plants need some energy source. One option for such an energy source is fossil fuel like coal, oil, and natural gas.
2,000,000,000(2 trillion) watts
In the US, 49 percent of total production of electricity
A lot
yes
coal power can be generated at night
Over half but not all of it
COAL
The US had an abundance of coal and natural gas. It is estimated that 50% of the electricity generated in the US was from coal through burning fossil fuels.
1 tonne of coal produce 1.83 tonnes of carbon dioxide when burned 1 tonne of coal generates 2.4 MWhours 0.416 tonne of coal generates 1 MWh 0.416 tonne of coal times 1.83 tonnes of CO2/tonne of coal = 0.7625 tonnes of CO2 are produced from 1 MWh of electricity generated by coal
is eletricity safe
About 1500 tons of coal
