Fossil fuels are deacyed plant matter from millions of years ago. The source of energy in the fuel is the carbon.
When plants grow they use carbon dioxide from the atmosphere and they separate the carbon from the oxygen by photosynthesis, which uses the Sun's energy directly because separating the atoms of carbon and oxygen requires energy. The carbon is used to make plant tissues while the oxygen is mostly emitted as a waste product.
But when the fuel is burned, the carbon is recombined with oxygen to produce carbon dioxide, and the formation of the chemical bonds beween the atoms releases energy as heat. This energy is the energy that was originally absorbed from the Sun all those millions of years ago.
So the Sun is the original source of energy for fossil fuels, but the energy was taken 50-100 million years ago and the amount being burned now produces too much CO2 for the Earth to deal with properly.
What else can I help you with?
What is the original source of energy for hydroelectricity?
The original source of energy for hydroelectricity is the gravitational potential energy of water stored in dams or reservoirs. When this water is released and flows through turbines, it generates mechanical energy, which is then converted into electrical energy.
What original source of energy is a tree?
A tree's original source of energy is sunlight, which it converts through photosynthesis into chemical energy stored in sugars. This process allows trees to grow, produce oxygen, and sustain themselves.
Animals get energy from the food they eat What is the original source of this energy?
The original source of energy for animals is the sun. Through the process of photosynthesis, plants convert sunlight into energy stored in carbohydrates, which animals then consume to obtain energy for their own metabolic processes.
Which type of energy is stored in fossil fuels?
Chemical energy is stored in fossil fuels, resulting from the organic matter that underwent decomposition over millions of years. This energy is released when the fossil fuels are burned or combusted.
What is the source for elastic energy?
Elastic energy is stored in an object when it is deformed or stretched. This energy is due to the potential energy stored in the bonds between atoms or molecules within the object, which can be released when the object returns to its original shape.
Where is the original source of energy stored?
ATP
Where is the energy source of fossil fuels found?
It comes from sunlight originally, since plants formed the original organic molecules. When dead plants and animals were buried, compressed, and heated, their products (coal, oil, gas) retained the chemical energy stored in their molecules millions of years earlier.
What is the original source of energy for hydroelectricity?
The original source of energy for hydroelectricity is the gravitational potential energy of water stored in dams or reservoirs. When this water is released and flows through turbines, it generates mechanical energy, which is then converted into electrical energy.
What are speed boats powered by?
A fossil fuel or wood. This is burnt to make heat and the heat boils water to make steam. The steam pressure is used to push things.However the original source of energy was the heat of the Sun (stored in the fossil fuel or wood).
What original source of energy is a tree?
A tree's original source of energy is sunlight, which it converts through photosynthesis into chemical energy stored in sugars. This process allows trees to grow, produce oxygen, and sustain themselves.
What is the main source of energy on the earth?
The main source is fossil fuels, but their energy is actually stored solar energy from long ago plants. The vast majority of energy expressed on the planet comes from the Sun.
The type of energy stored by fossil fuels is?
electromagnetic energy
Animals get energy from the food they eat What is the original source of this energy?
The original source of energy for animals is the sun. Through the process of photosynthesis, plants convert sunlight into energy stored in carbohydrates, which animals then consume to obtain energy for their own metabolic processes.

Elastic energy is stored in an object when it is deformed or stretched. This energy is due to the potential energy stored in the bonds between atoms or molecules within the object, which can be released when the object returns to its original shape.
What is the energy stored in fossil fuels such as coal?
Chemical potential energy
Is kinetic energy stored by fossil fuels?
No. Fossil fuels store chemical energy. It is this chemical energy we tap by using them for fuels.
