There are several disadvantages to using coal to generate electricity. When coal is burned, it releases lots of carbon dioxide, which is a problem because the atmosphere already has too much carbon dioxide and it is causing global warming. In addition, there are impurities in coal which result in other forms of air pollution, particularly sulfur dioxide which results in acid rain. Coal mining is also a dangerous activity that results in many deaths. And although there is a lot of coal, it is still not a renewable resource, and it will eventually run out, if we continue to burn it.
coal power can be generated at night
It takes one ton of coal to generate an average of 2500 KWH of electricity.
In some parts of the world, there is NO sun (to speak of) for as much as six months! In these areas, solar power is out of the question, unless there is a monstrously large storage system that can hold the energy during the six months of sunlight!
the good points of coal are it gives us electricity, we need to power our vehicles.Because you can reuse it but the bad thing is that it takes a long time to heat up ..... !!
if we stop using coal right now people would go crazy because their would be no electricity and we got so use to it that people say they cant live without it so coal is super important to people

The coal is used mostly to generate electricity.
no
bituminous coal
Coal power stations burn coal to heat water to produce steam, which is then used to spin electricity turbines to generate electricity. The burning coal releases carbon dioxide.Wind farms have blades which turn in the wind to spin electricity turbines to generate electricity. There are no harmful carbon dioxide emissions.
Coal is used to generate almost half of all electricity produced in the United States. Besides electric utility companies, industries and businesses with their own power plants use coal to generate electricity. Power plants burn coal to make steam. The steam turns turbines which generate electricity.
Compared to coal, an advantage of using oil to generate electricity is that generators can be taken out of use and then back into use more quickly and flexibly in response to changes in electricity demand, thereby reducing fuel usage. Coal is better suited to base load generation because of the long start-up time required, and will tend to be kept operating even when there is no demand for the electricity. However, natural gas is even more flexible than oil in this respect. A disadvantage of using oil to generate electricity is that the world's supplies of oil are limited, and electricity generation is an inappropriate use of such an adaptable fuel. Another disadvantage is that oil is a fossil fuel and its use therefore adds additional carbon dioxide to the atmosphere, contributing to the greenhouse effect and global warming.
Coal can't generate electricity by itself, but through the process of combustion, it can produce heat which can be used to produce steam that can run turbines which are connected to generators that produces electricity.
The fuel that India uses most to generate electricity is coal. Second to coal is hydro power and then natural gas resources.
