Because they are a non-renewable source and is created naturally.
hydroelectric energy is free to the fuel fossil
Fossil fuels are the main source of energy for many people because they are relatively inexpensive to extract and produce large amounts of energy when burned. They are also widely available and have a long history of use, making them a familiar and convenient choice for meeting energy needs. Additionally, existing infrastructure for extracting, transporting, and using fossil fuels makes them a preferred choice for many energy systems.
Solar energy is considered better than fossil fuels because it is a renewable and clean source of energy that does not produce harmful greenhouse gas emissions, unlike fossil fuels which contribute to climate change and air pollution.
We find must source better to get energy that hurt wont earth
Oil
fossil fuels can be used as an energy source to power all vehicles and most machinery
Nuclear energy that is the source of sun energy which in turn is the source of fossil and renewable energies.
No it is its own source of energy
Chemical energy
Fossil fuels.
Fossil fuels are exhaustible. Electric energy is an alternative.
