They don't have to be. Some fuels are fossil fuels, which are rapidly disappearing right now. Some examples of fossil fuels are oil, which we use for gas, and coal, which we use for heat and electricity. But fossil fuels take millions of years to make more, so we are rapidly using up the fossil fuels of the world.
What else can I help you with?
How do fossil fuels store energy?
Fossil fuels contain the chemical energy that plants and algae obtained from sunlight and then stored in sugars. Just as energy chemical energy is stored in sugars, chemical energy is stored in fossil fuels. All it takes to release it is enough heat and oxygen to cause the fuel to burn.
How does chemical energy convert into thermal energy?
When chemical bonds are broken during a chemical reaction, it releases the energy stored in those bonds as heat. This heat energy raises the temperature of the surroundings, converting chemical energy into thermal energy.
Are all fuels solid?
No, not all fuels are solid. Fuels can exist in different states - solid, liquid, or gas. Examples of liquid fuels include gasoline and diesel, while examples of gaseous fuels include natural gas and hydrogen.
Does all the energy start out as chemical energy?
No, our energy sources started from the sun (nuclear fusion) which made vegetation grow which turned into fossil fuels, or from stellar events which formed uranium. Then there are energy sources like wind, wave, and tidal, that are driven by the sun's energy, and direct solar energy. When we use fossil fuels, we are using a chemical reaction to release the energy contained in the fuel, but the original formation of the fossil fuel was driven by the sun. Energy from uranium is not chemical at all. Hydro power also depends on rainfall as the source of the energy, and that is caused by the sun's effect on the weather.
How can chemical energy be a bad thing?
Ask the fire brigade! If chemical energy is released too quickly it can be incredibly dangerous. The frequent bushfires of Australia and the recent forest fires in California are good examples. Chemical energy is also responsible for every explosion and shooting (except air guns etc.) there has ever been. On a different level, the chemical energy of fossil fuels is constantly at the centre of conflict and war. However, unless we want to starve to death, chemical energy is not something we can afford to dispense with. chemical energy is responsible for the corrosion of all metallic elements. This will cause a failure of the infrastructure of a country, if left unchecked.
All fuels are stores of?
Chemical energy
What are the examples of chemical energy?
Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction or to transform other chemical substances. Examples of chemical energy are: the digestive process, batteries, photosynthesis, burning gasoline, burning wood, using TNT, fire works, putting salt on a slug, alcohol, fermentation, and rusting.
When fuels are burnt the chemical energy changes to what?
When fuels are burned, the chemical energy in the fuels is converted into heat energy and light energy. This process releases energy stored in the chemical bonds of the fuel molecules, resulting in heat and light as byproducts.
What fuels release chemical energy when they are used?
Coal, gas,oil, and wood. All of these are burned (oxidized in air), which releases the chemical energy stored within its chemical bonds.

How does chemical energy convert into thermal energy?
When chemical bonds are broken during a chemical reaction, it releases the energy stored in those bonds as heat. This heat energy raises the temperature of the surroundings, converting chemical energy into thermal energy.
Where did the fossil fuels get there energy?
Ultimately, all energy only comes from the Sun. This is how the energy is transferred: Sun>plants>animals. Therefore, fossil fuels obtain their energy from plants itself and animals when they've consumed plants.
Are all fuels solid?
No, not all fuels are solid. Fuels can exist in different states - solid, liquid, or gas. Examples of liquid fuels include gasoline and diesel, while examples of gaseous fuels include natural gas and hydrogen.
What are the nonrenewable fuels start with the sun as there primary source of energy?
Nonrenewable fuels that start with the sun as their primary source of energy are fossil fuels. These fuels are created from organic materials that have been subjected to high pressure and heat over millions of years, which originally derived their energy from the sun. Examples include coal, oil, and natural gas.
What is the source of all energy?
The Sun is the primary source of energy for most living organisms on Earth. Solar energy is converted into chemical energy through processes like photosynthesis, which then fuels the food chain.
