Fossil fuels → important → largest sources of energy for electricity generation
Appliances such as:
- air con
- water heaters
- refrigerators → consume a lot of electricity
Some modes of transport also powered by electricity, while others directly powered by fossil fuels.
Fossil Fuels → formed from decaying plants and animals from millions of years ago.
- are mainly organic compounds that contain only carbon and hydrogen → known as Hydrocarbons Main Note
When fossil fuels burnt in presence of oxygen → main products formed → are and water.
- this exothermic reaction → known as Combustion Exothermic and Endothermic Reactions
- thermal energy generated from combustion of fossil fuels can be converted to other forms of energy.
Crude oil + natural gas → common forms of fossil fuels.
