Advantages and Disadvantages of Fossil

FuelsJessica, Myah and Abdullah

How much coal is required to run 100-Watt bulb, 24 hours a day, for one year?

Light Bulb’s Power = 0.1 kW (100/1000)

Number of hours in a year = 8,760 hours (365*24)

Total energy in a year = 876 kW (8,760*0.1)

Thermal energy content of coal = 6,150 kWh/ton

Thermal energy of coal to electricity = 40%

Electricity generated = 2,460 (0.4 *6,150)

Coal required = 325 kg (876/2,460 = 0.357 tons)

Advantages

Formed from fossilized plants and animals, making it easy to find.

Generates huge amounts of electricity. Power plants using fossil fuels can be almost

anywhere.

Disadvantages

Non- renewable resource Releases gases into atmosphere Won’t always be available Pollution and acid rain
