Advantages and Disadvantages of Fossil
Fuels
Jessica, 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
