Advantages:-
1. coal is cheap to buy( not all but some varieties)
2. it serves as a fuel in industries and hence is very important
3. it can be used to generate electricity
4.powdered coal has been liquified by using hydrogen under high pressure. this liquid coal is mainly used to power ships
5.it can be used as a good reducing agent (for producing iron and steel)
6.it burns without smoke.
disadvantages-
1. it is non-renewable resource
2. it emits harmful gases (mostly carbon dioxide (CO2)) which cause both pollution and global warming
3.it is a bad conductor of heat and electricity
4. one of the gas emitted is carbon monooxide. This is highly poisonous and even 1% of it consumed can cause death
5.it takes thousands of years to form
6. it cannot be recycled
It keeps me in a job !!
The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs electric motors and it's only emission is water vapour. The disadvantages of using hydrogen fuel cells is that hydrogen does not occur naturally on Earth and thus is not an energy source. It takes a great deal of energy to extract Hydrogen from water. Hope this helps! :)

Uranium is very important as a nuclear fuel for nuclear power plants. But uranium is toxic and radioactive.
Coal is not a suitable automotive fuel as:It is not compatible with internal combustion enginesRequires complex handling and combustion systemsProduces solid wasteHas no distribution system at the user levelContains sulfur compoundsEmits radiationRequires continuous firing - no off on on capacity
an advantage is that it will only cost 50p a gallon a disadvantage is that it will really smell
There are quite a few advantages and disadvantages of fuel price hikes. One disadvantage is that less fuel is purchased bringing in less money.
The advantages are that u can get to places faster. the disadvantages are it pollutes and wastes money on fuel.
advantages , it costs a bit less than petrol disavantages: burns alot we love k.k and that does not burn any fuel
diasadvantages... low efficiency
what are the disadvantages of land transport?Disadvantages: Land transport is slower.Destinations are more limited.Runs on more fuel, if using a land vehicle.Advantages: Land transport is safer than sea transport.
