Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
An advantage of using coal and natural gas is that is is virtually an endless natural resource.
Coal and natural gas are great resources because they do take millions of years to replace and have a virtually endless supply.
No, relative density is relative to water. Therefore, oil with a relative density of 0.9 is 90% the density of water. Which is why oil floats on top of water. Put both in a glass to see.
Oil, Coal and Natural Gas are all Natural Resources that happen to be non-renewable fossil fuels.
Coal, Oil, and natural gas.
the countries that have deposits of coal and oil have the advantage to have coal to heat up homes, give a warming fire etc, and for countries that have oil deposits can have more petrol, cooking oil :), oil for lamps etc.
An advantage of using coal and natural gas is that is is virtually an endless natural resource.
Advantage: It may help the areas where it is being transported. Disadvantage: It is really expensive to import oil.
One advantage is: The energy that you have to put intothe solar cell is free. No oil, gas, coal, etc.
Use water and coal. :D
coal and oil come from many different places. Like coal from mines. oil from the ground.

Coal AND Oil
The advantage of using solar, wind, and hydroelectric energy is that these energy sources are environmentally friendly, and they do not run out. The disadvantage is that they are generally more expensive to implement than traditional sources of energy like oil and gas.

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.
